Emotion

From Wikipedia, the free encyclopedia

Emotion is any conscious experience characterized by intense mental activity and a certain degree of pleasure or displeasure. Scientific discourse has drifted to other meanings and there is no consensus on a definition. Emotion is often intertwined with mood, temperament, personality, disposition, and motivation. In some theories, cognition is an important aspect of emotion. Those acting primarily on the emotions they are feeling may seem as if they are not thinking, but mental processes are still essential, particularly in the interpretation of events. For example, the realization of our believing that we are in a dangerous situation and the subsequent arousal of our body's nervous system (rapid heartbeat and breathing, sweating, muscle tension) is integral to the experience of our feeling afraid. Other theories, however, claim that emotion is separate from and can precede cognition. Consciously experiencing an emotion is exhibiting a mental representation of that emotion from a past or hypothetical experience, which is linked back to a content state of pleasure or displeasure. The content states are established by verbal explanations of experiences, describing an internal state.

Emotions are complex. According to some theories, they are states of feeling that result in physical and psychological changes that influence our behavior. The physiology of emotion is closely linked to arousal of the nervous system with various states and strengths of arousal relating, apparently, to particular emotions. Emotion is also linked to behavioral tendency. Extroverted people are more likely to be social and express their emotions, while introverted people are more likely to be more socially withdrawn and conceal their emotions. Emotion is often the driving force behind motivation, positive or negative. According to other theories, emotions are not causal forces but simply syndromes of components, which might include motivation, feeling, behavior, and physiological changes, but no one of these components is the emotion. Nor is the emotion an entity that causes these components.

Emotions involve different components, such as subjective experience, cognitive processes, expressive behavior, psychophysiological changes, and instrumental behavior. At one time, academics attempted to identify the emotion with one of the components: William James with a subjective experience, behaviorists with instrumental behavior, psychophysiologists with physiological changes, and so on. More recently, emotion is said to consist of all the components. The different components of emotion are categorized somewhat differently depending on the academic discipline. In psychology and philosophy, emotion typically includes a subjective, conscious experience characterized primarily by psychophysiological expressions, biological reactions, and mental states. A similar multicomponential description of emotion is found in sociology. For example, Peggy Thoits described emotions as involving physiological components, cultural or emotional labels (anger, surprise, etc.), expressive body actions, and the appraisal of situations and contexts.

Research on emotion has increased significantly over the past two decades with many fields contributing including psychology, neuroscience, endocrinology, medicine, history, sociology, and computer science. The numerous theories that attempt to explain the origin, neurobiology, experience, and function of emotions have only fostered more intense research on this topic. Current areas of research in the concept of emotion include the development of materials that stimulate and elicit emotion. In addition PET scans and fMRI scans help study the affective processes in the brain.

"Emotions can be defined as a positive or negative experience that is associated with a particular pattern of physiological activity." Emotions produce different physiological, behavioral and cognitive changes. The original role of emotions was to motivate adaptive behaviors that in the past would have contributed to the survival of humans. Emotions are responses to significant internal and external events.

Etymology, definitions, history and differentiation

Sixteen faces expressing the human passions-coloured engraving by J. Pass, 1821, after Charles Le Brun

The word "emotion" dates back to 1579, when it was adapted from the French word émouvoir, which means "to stir up". The term emotion was introduced into academic discussion as a catch-all term to passions, sentiments and affections. The word emotion was coined in the early 1800s by Thomas Brown and it is around the 1830s that the modern concept of emotion first emerged. "No one felt emotions before about 1830. Instead they felt other things - "passions", "accidents of the soul", "moral sentiments" - and explained them very differently from how we understand emotions today."

According to one dictionary, the earliest precursors of the word likely dates back to the very origins of language. The modern word emotion is heterogeneous In some uses of the word, emotions are intense feelings that are directed at someone or something. On the other hand, emotion can be used to refer to states that are mild (as in annoyed or content) and to states that are not directed at anything (as in anxiety and depression). One line of research thus looks at the meaning of the word emotion in everyday language and this usage is rather different from that in academic discourse. Another line of research asks about languages other than English, and one interesting finding is that many languages have a similar but not identical term In anthropology, an inability to express or perceive emotion is sometimes referred to as alexithymia.

Emotions have been described by some theorists as discrete and consistent responses to internal or external events which have a particular significance for the organism. Emotions are brief in duration and consist of a coordinated set of responses, which may include verbal, physiological, behavioral, and neural mechanisms. Psychotherapist Michael C. Graham describes all emotions as existing on a continuum of intensity. Thus fear might range from mild concern to terror or shame might range from simple embarrassment to toxic shame. Emotions have also been described as biologically given and a result of evolution because they provided good solutions to ancient and recurring problems that faced our ancestors. Moods are feelings that tend to be less intense than emotions and that often lack a contextual stimulus.

Emotion can be differentiated from a number of similar constructs within the field of affective neuroscience:
  • Feelings are best understood as a subjective representation of emotions, private to the individual experiencing them.
  • Moods are diffuse affective states that generally last for much longer durations than emotions and are also usually less intense than emotions.
  • Affect is an encompassing term, used to describe the topics of emotion, feelings, and moods together, even though it is commonly used interchangeably with emotion.
In addition, relationships exist between emotions, such as having positive or negative influences, with direct opposites existing. These concepts are described in contrasting and categorization of emotions. Graham differentiates emotions as functional or dysfunctional and argues all functional emotions have benefits.

Components

In Scherer's components processing model of emotion, five crucial elements of emotion are said to exist. From the component processing perspective, emotion experience is said to require that all of these processes become coordinated and synchronized for a short period of time, driven by appraisal processes. Although the inclusion of cognitive appraisal as one of the elements is slightly controversial, since some theorists make the assumption that emotion and cognition are separate but interacting systems, the component processing model provides a sequence of events that effectively describes the coordination involved during an emotional episode.
  • Cognitive appraisal: provides an evaluation of events and objects.
  • Bodily symptoms: the physiological component of emotional experience.
  • Action tendencies: a motivational component for the preparation and direction of motor responses.
  • Expression: facial and vocal expression almost always accompanies an emotional state to communicate reaction and intention of actions.
  • Feelings: the subjective experience of emotional state once it has occurred.

Classification

A distinction can be made between emotional episodes and emotional dispositions. Emotional dispositions are also comparable to character traits, where someone may be said to be generally disposed to experience certain emotions. For example, an irritable person is generally disposed to feel irritation more easily or quickly than others do. Finally, some theorists place emotions within a more general category of "affective states" where affective states can also include emotion-related phenomena such as pleasure and pain, motivational states (for example, hunger or curiosity), moods, dispositions and traits.

The classification of emotions has mainly been researched from two fundamental viewpoints. The first viewpoint is that emotions are discrete and fundamentally different constructs while the second viewpoint asserts that emotions can be characterized on a dimensional basis in groupings.

Basic emotions

Examples of basic emotions

For more than 40 years, Paul Ekman has supported the view that emotions are discrete, measurable, and physiologically distinct. Ekman's most influential work revolved around the finding that certain emotions appeared to be universally recognized, even in cultures that were preliterate and could not have learned associations for facial expressions through media. Another classic study found that when participants contorted their facial muscles into distinct facial expressions (for example, disgust), they reported subjective and physiological experiences that matched the distinct facial expressions. His research findings led him to classify six emotions as basic: anger, disgust, fear, happiness, sadness and surprise. Later in his career, Ekman theorized that other universal emotions may exist beyond these six. In light of this, recent cross-cultural studies led by Daniel Cordaro and Dacher Keltner, both former students of Ekman, extended the list of universal emotions. In addition to the original six, these studies provided evidence for amusement, awe, contentment, desire, embarrassment, pain, relief, and sympathy in both facial and vocal expressions. They also found evidence for boredom, confusion, interest, pride, and shame facial expressions, as well as contempt, interest, relief, and triumph vocal expressions.

Robert Plutchik agreed with Ekman's biologically driven perspective but developed the "wheel of emotions", suggesting eight primary emotions grouped on a positive or negative basis: joy versus sadness; anger versus fear; trust versus disgust; and surprise versus anticipation. Some basic emotions can be modified to form complex emotions. The complex emotions could arise from cultural conditioning or association combined with the basic emotions. Alternatively, similar to the way primary colors combine, primary emotions could blend to form the full spectrum of human emotional experience. For example, interpersonal anger and disgust could blend to form contempt. Relationships exist between basic emotions, resulting in positive or negative influences.

Multi-dimensional analysis

Two dimensions of emotion

Through the use of multidimensional scaling, psychologists can map out similar emotional experiences, which allows a visual depiction of the "emotional distance" between experiences. A further step can be taken by looking at the map's dimensions of the emotional experiences. The emotional experiences are divided into two dimensions known as valence (how negative or positive the experience feels) and arousal (how energized or enervated the experience feels). These two dimensions can be depicted on a 2D coordinate map. This two-dimensional map was theorized to capture one important component of emotion called core affect. Core affect is not the only component to emotion, but gives the emotion its hedonic and felt energy.

The idea that core affect is but one component of the emotion led to a theory called “psychological construction.” According to this theory, an emotional episode consists of a set of components, each of which is an ongoing process and none of which is necessary or sufficient for the emotion to be instantiated. The set of components is not fixed, either by human evolutionary history or by social norms and roles. Instead, the emotional episode is assembled at the moment of its occurrence to suit its specific circumstances. One implication is that all cases of, for example, fear are not identical but instead bear a family resemblance to one another.

Theories

Ancient Greece, Ancient China, the Islamic Golden Age, and the Middle Ages

Theories about emotions stretch back to at least as far as the stoics of Ancient Greece and Ancient China. In China, excessive emotion was believed to cause damage to qi, which in turn, damages the vital organs. The four humours theory made popular by Hippocrates contributed to the study of emotion in the same way that it did for medicine.

During the Islamic Golden Age, Persian polymath Avicenna theorized about the influence of emotions on health and behaviors, suggesting the need to manage emotions. Western philosophy regarded emotion in varying ways. In stoic theories it was seen as a hindrance to reason and therefore a hindrance to virtue. Aristotle believed that emotions were an essential component of virtue. In the Aristotelian view all emotions (called passions) corresponded to appetites or capacities. During the Middle Ages, the Aristotelian view was adopted and further developed by scholasticism and Thomas Aquinas in particular. There are also theories of emotions in the works of philosophers such as René Descartes, Niccolò Machiavelli, Baruch Spinoza, Thomas Hobbes, and David Hume. In the 19th century emotions were considered adaptive and were studied more frequently from an empiricist psychiatric perspective.

Evolutionary theories

19th century
Perspectives on emotions from evolutionary theory were initiated during the mid-late 19th century with Charles Darwin's 1872 book The Expression of the Emotions in Man and Animals. Darwin argued that emotions actually served a purpose for humans, in communication and also in aiding their survival. Darwin, therefore, argued that emotions evolved via natural selection and therefore have universal cross-cultural counterparts. Darwin also detailed the virtues of experiencing emotions and the parallel experiences that occur in animals. This led the way for animal research on emotions and the eventual determination of the neural underpinnings of emotion.
Contemporary
More contemporary views along the evolutionary psychology spectrum posit that both basic emotions and social emotions evolved to motivate (social) behaviors that were adaptive in the ancestral environment. Current research suggests that emotion is an essential part of any human decision-making and planning, and the famous distinction made between reason and emotion is not as clear as it seems. Paul D. MacLean claims that emotion competes with even more instinctive responses, on one hand, and the more abstract reasoning, on the other hand. The increased potential in neuroimaging has also allowed investigation into evolutionarily ancient parts of the brain. Important neurological advances were derived from these perspectives in the 1990s by Joseph E. LeDoux and António Damásio.

Research on social emotion also focuses on the physical displays of emotion including body language of animals and humans. For example, spite seems to work against the individual but it can establish an individual's reputation as someone to be feared. Shame and pride can motivate behaviors that help one maintain one's standing in a community, and self-esteem is one's estimate of one's status.

Somatic theories

Somatic theories of emotion claim that bodily responses, rather than cognitive interpretations, are essential to emotions. The first modern version of such theories came from William James in the 1880s. The theory lost favor in the 20th century, but has regained popularity more recently due largely to theorists such as John Cacioppo, António Damásio, Joseph E. LeDoux, and Robert Zajonc who are able to appeal to neurological evidence.

James–Lange theory

In his 1884 article William James argued that feelings and emotions were secondary to physiological phenomena. In his theory, James proposed that the perception of what he called an "exciting fact" directly led to a physiological response, known as "emotion." To account for different types of emotional experiences, James proposed that stimuli trigger activity in the autonomic nervous system, which in turn produces an emotional experience in the brain. The Danish psychologist Carl Lange also proposed a similar theory at around the same time, and therefore this theory became known as the James–Lange theory. As James wrote, "the perception of bodily changes, as they occur, is the emotion." James further claims that "we feel sad because we cry, angry because we strike, afraid because we tremble, and either we cry, strike, or tremble because we are sorry, angry, or fearful, as the case may be."

An example of this theory in action would be as follows: An emotion-evoking stimulus (snake) triggers a pattern of physiological response (increased heart rate, faster breathing, etc.), which is interpreted as a particular emotion (fear). This theory is supported by experiments in which by manipulating the bodily state induces a desired emotional state. Some people may believe that emotions give rise to emotion-specific actions, for example, "I'm crying because I'm sad," or "I ran away because I was scared." The issue with the James–Lange theory is that of causation (bodily states causing emotions and being a priori), not that of the bodily influences on emotional experience (which can be argued and is still quite prevalent today in biofeedback studies and embodiment theory).

Although mostly abandoned in its original form, Tim Dalgleish argues that most contemporary neuroscientists have embraced the components of the James-Lange theory of emotions.
The James–Lange theory has remained influential. Its main contribution is the emphasis it places on the embodiment of emotions, especially the argument that changes in the bodily concomitants of emotions can alter their experienced intensity. Most contemporary neuroscientists would endorse a modified James–Lange view in which bodily feedback modulates the experience of emotion." (p. 583)

Cannon–Bard theory

Walter Bradford Cannon agreed that physiological responses played a crucial role in emotions, but did not believe that physiological responses alone could explain subjective emotional experiences. He argued that physiological responses were too slow and often imperceptible and this could not account for the relatively rapid and intense subjective awareness of emotion. He also believed that the richness, variety, and temporal course of emotional experiences could not stem from physiological reactions, that reflected fairly undifferentiated fight or flight responses. An example of this theory in action is as follows: An emotion-evoking event (snake) triggers simultaneously both a physiological response and a conscious experience of an emotion.

Phillip Bard contributed to the theory with his work on animals. Bard found that sensory, motor, and physiological information all had to pass through the diencephalon (particularly the thalamus), before being subjected to any further processing. Therefore, Cannon also argued that it was not anatomically possible for sensory events to trigger a physiological response prior to triggering conscious awareness and emotional stimuli had to trigger both physiological and experiential aspects of emotion simultaneously.

Two-factor theory

Stanley Schachter formulated his theory on the earlier work of a Spanish physician, Gregorio Marañón, who injected patients with epinephrine and subsequently asked them how they felt. Marañón found that most of these patients felt something but in the absence of an actual emotion-evoking stimulus, the patients were unable to interpret their physiological arousal as an experienced emotion. Schachter did agree that physiological reactions played a big role in emotions. He suggested that physiological reactions contributed to emotional experience by facilitating a focused cognitive appraisal of a given physiologically arousing event and that this appraisal was what defined the subjective emotional experience. Emotions were thus a result of two-stage process: general physiological arousal, and experience of emotion. For example, the physiological arousal, heart pounding, in a response to an evoking stimulus, the sight of a bear in the kitchen. The brain then quickly scans the area, to explain the pounding, and notices the bear. Consequently, the brain interprets the pounding heart as being the result of fearing the bear. With his student, Jerome Singer, Schachter demonstrated that subjects can have different emotional reactions despite being placed into the same physiological state with an injection of epinephrine. Subjects were observed to express either anger or amusement depending on whether another person in the situation (a confederate) displayed that emotion. Hence, the combination of the appraisal of the situation (cognitive) and the participants' reception of adrenaline or a placebo together determined the response. This experiment has been criticized in Jesse Prinz's (2004) Gut Reactions.

Cognitive theories

With the two-factor theory now incorporating cognition, several theories began to argue that cognitive activity in the form of judgments, evaluations, or thoughts were entirely necessary for an emotion to occur. One of the main proponents of this view was Richard Lazarus who argued that emotions must have some cognitive intentionality. The cognitive activity involved in the interpretation of an emotional context may be conscious or unconscious and may or may not take the form of conceptual processing.

Lazarus' theory is very influential; emotion is a disturbance that occurs in the following order:
  1. Cognitive appraisal—The individual assesses the event cognitively, which cues the emotion.
  2. Physiological changes—The cognitive reaction starts biological changes such as increased heart rate or pituitary adrenal response.
  3. Action—The individual feels the emotion and chooses how to react.
For example: Jenny sees a snake.
  1. Jenny cognitively assesses the snake in her presence. Cognition allows her to understand it as a danger.
  2. Her brain activates adrenaline gland which pumps adrenaline through her blood stream resulting in increased heartbeat.
  3. Jenny screams and runs away.
Lazarus stressed that the quality and intensity of emotions are controlled through cognitive processes. These processes underline coping strategies that form the emotional reaction by altering the relationship between the person and the environment.

George Mandler provided an extensive theoretical and empirical discussion of emotion as influenced by cognition, consciousness, and the autonomic nervous system in two books (Mind and Emotion, 1975, and Mind and Body: Psychology of Emotion and Stress, 1984.

There are some theories on emotions arguing that cognitive activity in the form of judgments, evaluations, or thoughts are necessary in order for an emotion to occur. A prominent philosophical exponent is Robert C. Solomon (for example, The Passions, Emotions and the Meaning of Life, 1993). Solomon claims that emotions are judgments. He has put forward a more nuanced view which response to what he has called the ‘standard objection’ to cognitivism, the idea that a judgment that something is fearsome can occur with or without emotion, so judgment cannot be identified with emotion. The theory proposed by Nico Frijda where appraisal leads to action tendencies is another example.

It has also been suggested that emotions (affect heuristics, feelings and gut-feeling reactions) are often used as shortcuts to process information and influence behavior. The affect infusion model (AIM) is a theoretical model developed by Joseph Forgas in the early 1990s that attempts to explain how emotion and mood interact with one's ability to process information.
Perceptual theory
Theories dealing with perception either use one or multiples perceptions in order to find an emotion (Goldie, 2007). A recent hybrid of the somatic and cognitive theories of emotion is the perceptual theory. This theory is neo-Jamesian in arguing that bodily responses are central to emotions, yet it emphasizes the meaningfulness of emotions or the idea that emotions are about something, as is recognized by cognitive theories. The novel claim of this theory is that conceptually-based cognition is unnecessary for such meaning. Rather the bodily changes themselves perceive the meaningful content of the emotion because of being causally triggered by certain situations. In this respect, emotions are held to be analogous to faculties such as vision or touch, which provide information about the relation between the subject and the world in various ways. A sophisticated defense of this view is found in philosopher Jesse Prinz's book Gut Reactions, and psychologist James Laird's book Feelings.
Affective events theory
Affective events theory is a communication-based theory developed by Howard M. Weiss and Russell Cropanzano (1996), that looks at the causes, structures, and consequences of emotional experience (especially in work contexts). This theory suggests that emotions are influenced and caused by events which in turn influence attitudes and behaviors. This theoretical frame also emphasizes time in that human beings experience what they call emotion episodes— a "series of emotional states extended over time and organized around an underlying theme." This theory has been utilized by numerous researchers to better understand emotion from a communicative lens, and was reviewed further by Howard M. Weiss and Daniel J. Beal in their article, "Reflections on Affective Events Theory", published in Research on Emotion in Organizations in 2005.

Situated perspective on emotion

A situated perspective on emotion, developed by Paul E. Griffiths and Andrea Scarantino, emphasizes the importance of external factors in the development and communication of emotion, drawing upon the situationism approach in psychology. This theory is markedly different from both cognitivist and neo-Jamesian theories of emotion, both of which see emotion as a purely internal process, with the environment only acting as a stimulus to the emotion. In contrast, a situationist perspective on emotion views emotion as the product of an organism investigating its environment, and observing the responses of other organisms. Emotion stimulates the evolution of social relationships, acting as a signal to mediate the behavior of other organisms. In some contexts, the expression of emotion (both voluntary and involuntary) could be seen as strategic moves in the transactions between different organisms. The situated perspective on emotion states that conceptual thought is not an inherent part of emotion, since emotion is an action-oriented form of skillful engagement with the world. Griffiths and Scarantino suggested that this perspective on emotion could be helpful in understanding phobias, as well as the emotions of infants and animals.

Genetics

Emotions can motivate social interactions and relationships and therefore are directly related with basic physiology, particularly with the stress systems. This is important because emotions are related to the anti-stress complex, with an oxytocin-attachment system, which plays a major role in bonding. Emotional phenotype temperaments affect social connectedness and fitness in complex social systems (Kurt Kortschal 2013). These characteristics are shared with other species and taxa and are due to the effects of genes and their continuous transmission. Information that is encoded in the DNA sequences provides the blueprint for assembling proteins that make up our cells. Zygotes require genetic information from their parental germ cells, and at every speciation event, heritable traits that have enabled its ancestor to survive and reproduce successfully are passed down along with new traits that could be potentially beneficial to the offspring.

In the five million years since the lineages leading to modern humans and chimpanzees split, only about 1.2% of their genetic material has been modified. This suggests that everything that separates us from chimpanzees must be encoded in that very small amount of DNA, including our behaviors. Students that study animal behaviors have only identified intraspecific examples of gene-dependent behavioral phenotypes. In voles (Microtus spp.) minor genetic differences have been identified in a vasopressin receptor gene that corresponds to major species differences in social organization and the mating system (Hammock & Young 2005). Another potential example with behavioral differences is the FOCP2 gene, which is involved in neural circuitry handling speech and language (Vargha-Khadem et al. 2005). Its present form in humans differed from that of the chimpanzees by only a few mutations and has been present for about 200,000 years, coinciding with the beginning of modern humans (Enard et al. 2002). Speech, language, and social organization are all part of the basis for emotions.

Neurocircuitry

Based on discoveries made through neural mapping of the limbic system, the neurobiological explanation of human emotion is that emotion is a pleasant or unpleasant mental state organized in the limbic system of the mammalian brain. If distinguished from reactive responses of reptiles, emotions would then be mammalian elaborations of general vertebrate arousal patterns, in which neurochemicals (for example, dopamine, noradrenaline, and serotonin) step-up or step-down the brain's activity level, as visible in body movements, gestures and postures. Emotions can likely be mediated by pheromones.

For example, the emotion of love is proposed to be the expression of paleocircuits of the mammalian brain (specifically, modules of the cingulate gyrus) which facilitate the care, feeding, and grooming of offspring. Paleocircuits are neural platforms for bodily expression configured before the advent of cortical circuits for speech. They consist of pre-configured pathways or networks of nerve cells in the forebrain, brain stem and spinal cord.

The motor centers of reptiles react to sensory cues of vision, sound, touch, chemical, gravity, and motion with pre-set body movements and programmed postures. With the arrival of night-active mammals, smell replaced vision as the dominant sense, and a different way of responding arose from the olfactory sense, which is proposed to have developed into mammalian emotion and emotional memory. The mammalian brain invested heavily in olfaction to succeed at night as reptiles slept—one explanation for why olfactory lobes in mammalian brains are proportionally larger than in the reptiles. These odor pathways gradually formed the neural blueprint for what was later to become our limbic brain.


Emotions are thought to be related to certain activities in brain areas that direct our attention, motivate our behavior, and determine the significance of what is going on around us. Pioneering work by Broca (1878), Papez (1937), and MacLean (1952) suggested that emotion is related to a group of structures in the center of the brain called the limbic system, which includes the hypothalamus, cingulate cortex, hippocampi, and other structures. More recent research has shown that some of these limbic structures are not as directly related to emotion as others are while some non-limbic structures have been found to be of greater emotional relevance.

In 2011, Lövheim proposed a direct relation between specific combinations of the levels of the signal substances dopamine, noradrenaline and serotonin and eight basic emotions. A model was presented where the signal substances form the axes of a coordinate system, and the eight basic emotions according to Silvan Tomkins are placed in the eight corners. Anger is, according to the model, for example produced by the combination of low serotonin, high dopamine and high noradrenaline.

Prefrontal cortex

There is ample evidence that the left prefrontal cortex is activated by stimuli that cause positive approach. If attractive stimuli can selectively activate a region of the brain, then logically the converse should hold, that selective activation of that region of the brain should cause a stimulus to be judged more positively. This was demonstrated for moderately attractive visual stimuli and replicated and extended to include negative stimuli.

Two neurobiological models of emotion in the prefrontal cortex made opposing predictions. The Valence Model predicted that anger, a negative emotion, would activate the right prefrontal cortex. The Direction Model predicted that anger, an approach emotion, would activate the left prefrontal cortex. The second model was supported.

This still left open the question of whether the opposite of approach in the prefrontal cortex is better described as moving away (Direction Model), as unmoving but with strength and resistance (Movement Model), or as unmoving with passive yielding (Action Tendency Model). Support for the Action Tendency Model (passivity related to right prefrontal activity) comes from research on shyness and research on behavioral inhibition. Research that tested the competing hypotheses generated by all four models also supported the Action Tendency Model.

Homeostatic/primordial emotion

Another neurological approach proposed by Bud Craig in 2003 distinguishes two classes of emotion: "classical" emotions such as love, anger and fear that are evoked by environmental stimuli, and "homeostatic emotions" – attention-demanding feelings evoked by body states, such as pain, hunger and fatigue, that motivate behavior (withdrawal, eating or resting in these examples) aimed at maintaining the body's internal milieu at its ideal state.

Derek Denton calls the latter "primordial emotions" and defines them as "the subjective element of the instincts, which are the genetically programmed behavior patterns which contrive homeostasis. They include thirst, hunger for air, hunger for food, pain and hunger for specific minerals etc. There are two constituents of a primordial emotion--the specific sensation which when severe may be imperious, and the compelling intention for gratification by a consummatory act."

Disciplinary approaches

Many different disciplines have produced work on the emotions. Human sciences study the role of emotions in mental processes, disorders, and neural mechanisms. In psychiatry, emotions are examined as part of the discipline's study and treatment of mental disorders in humans. Nursing studies emotions as part of its approach to the provision of holistic health care to humans. Psychology examines emotions from a scientific perspective by treating them as mental processes and behavior and they explore the underlying physiological and neurological processes. In neuroscience sub-fields such as social neuroscience and affective neuroscience, scientists study the neural mechanisms of emotion by combining neuroscience with the psychological study of personality, emotion, and mood. In linguistics, the expression of emotion may change to the meaning of sounds. In education, the role of emotions in relation to learning is examined.

Social sciences often examine emotion for the role that it plays in human culture and social interactions. In sociology, emotions are examined for the role they play in human society, social patterns and interactions, and culture. In anthropology, the study of humanity, scholars use ethnography to undertake contextual analyses and cross-cultural comparisons of a range of human activities. Some anthropology studies examine the role of emotions in human activities. In the field of communication sciences, critical organizational scholars have examined the role of emotions in organizations, from the perspectives of managers, employees, and even customers. A focus on emotions in organizations can be credited to Arlie Russell Hochschild's concept of emotional labor. The University of Queensland hosts EmoNet, an e-mail distribution list representing a network of academics that facilitates scholarly discussion of all matters relating to the study of emotion in organizational settings. The list was established in January 1997 and has over 700 members from across the globe.

In economics, the social science that studies the production, distribution, and consumption of goods and services, emotions are analyzed in some sub-fields of microeconomics, in order to assess the role of emotions on purchase decision-making and risk perception. In criminology, a social science approach to the study of crime, scholars often draw on behavioral sciences, sociology, and psychology; emotions are examined in criminology issues such as anomie theory and studies of "toughness," aggressive behavior, and hooliganism. In law, which underpins civil obedience, politics, economics and society, evidence about people's emotions is often raised in tort law claims for compensation and in criminal law prosecutions against alleged lawbreakers (as evidence of the defendant's state of mind during trials, sentencing, and parole hearings). In political science, emotions are examined in a number of sub-fields, such as the analysis of voter decision-making.

In philosophy, emotions are studied in sub-fields such as ethics, the philosophy of art (for example, sensory–emotional values, and matters of taste and sentimentality), and the philosophy of music (see also Music and emotion). In history, scholars examine documents and other sources to interpret and analyze past activities; speculation on the emotional state of the authors of historical documents is one of the tools of interpretation. In literature and film-making, the expression of emotion is the cornerstone of genres such as drama, melodrama, and romance. In communication studies, scholars study the role that emotion plays in the dissemination of ideas and messages. Emotion is also studied in non-human animals in ethology, a branch of zoology which focuses on the scientific study of animal behavior. Ethology is a combination of laboratory and field science, with strong ties to ecology and evolution. Ethologists often study one type of behavior (for example, aggression) in a number of unrelated animals.

History

The history of emotions has become an increasingly popular topic recently, with some scholars arguing that it is an essential category of analysis, not unlike class, race, or gender. Historians, like other social scientists, assume that emotions, feelings and their expressions are regulated in different ways by both different cultures and different historical times, and the constructivist school of history claims even that some sentiments and meta-emotions, for example Schadenfreude, are learnt and not only regulated by culture. Historians of emotion trace and analyse the changing norms and rules of feeling, while examining emotional regimes, codes, and lexicons from social, cultural, or political history perspectives. Others focus on the history of medicine, science, or psychology. What somebody can and may feel (and show) in a given situation, towards certain people or things, depends on social norms and rules; thus historically variable and open to change. Several research centers have opened in the past few years in Germany, England, Spain, Sweden, and Australia.

Furthermore, research in historical trauma suggests that some traumatic emotions can be passed on from parents to offspring to second and even third generation, presented as examples of transgenerational trauma.

Sociology

A common way in which emotions are conceptualized in sociology is in terms of the multidimensional characteristics including cultural or emotional labels (for example, anger, pride, fear, happiness), physiological changes (for example, increased perspiration, changes in pulse rate), expressive facial and body movements (for example, smiling, frowning, baring teeth), and appraisals of situational cues. One comprehensive theory of emotional arousal in humans has been developed by Jonathan Turner (2007: 2009). Two of the key eliciting factors for the arousal of emotions within this theory are expectations states and sanctions. When people enter a situation or encounter with certain expectations for how the encounter should unfold, they will experience different emotions depending on the extent to which expectations for Self, other and situation are met or not met. People can also provide positive or negative sanctions directed at Self or other which also trigger different emotional experiences in individuals. Turner analyzed a wide range of emotion theories across different fields of research including sociology, psychology, evolutionary science, and neuroscience. Based on this analysis, he identified four emotions that all researchers consider being founded on human neurology including assertive-anger, aversion-fear, satisfaction-happiness, and disappointment-sadness. These four categories are called primary emotions and there is some agreement amongst researchers that these primary emotions become combined to produce more elaborate and complex emotional experiences. These more elaborate emotions are called first-order elaborations in Turner's theory and they include sentiments such as pride, triumph, and awe. Emotions can also be experienced at different levels of intensity so that feelings of concern are a low-intensity variation of the primary emotion aversion-fear whereas depression is a higher intensity variant.

Attempts are frequently made to regulate emotion according to the conventions of the society and the situation based on many (sometimes conflicting) demands and expectations which originate from various entities. The emotion of anger is in many cultures discouraged in girls and women (expression of anger is also discouraged in men because a man is seen as a threat if he shows anger, which causes people to avoid him or treat him as a danger - particularly women), while fear is discouraged in boys and men. Expectations attached to social roles, such as "acting as man" and not as a woman, and the accompanying "feeling rules" contribute to the differences in expression of certain emotions. Some cultures encourage or discourage happiness, sadness, or jealousy, and the free expression of the emotion of disgust is considered socially unacceptable in most cultures. Some social institutions are seen as based on certain emotion, such as love in the case of contemporary institution of marriage. In advertising, such as health campaigns and political messages, emotional appeals are commonly found. Recent examples include no-smoking health campaigns and political campaigns emphasizing the fear of terrorism.

Sociological attention to emotion has varied over time. Émile Durkheim (1915/1965) wrote about the collective effervescence or emotional energy that was experienced by members of totemic rituals in Australian aborigine society. He explained how the heightened state of emotional energy achieved during totemic rituals transported individuals above themselves giving them the sense that they were in the presence of a higher power, a force, that was embedded in the sacred objects that were worshipped. These feelings of exaltation, he argued, ultimately lead people to believe that there were forces that governed sacred objects.

In the 1990s, sociologists focused on different aspects of specific emotions and how these emotions were socially relevant. For Cooley (1992), pride and shame were the most important emotions that drive people to take various social actions. During every encounter, he proposed that we monitor ourselves through the "looking glass" that the gestures and reactions of others provide. Depending on these reactions, we either experience pride or shame and this results in particular paths of action. Retzinger (1991) conducted studies of married couples who experienced cycles of rage and shame. Drawing predominantly on Goffman and Cooley's work, Scheff (1990) developed a micro sociological theory of the social bond. The formation or disruption of social bonds is dependent on the emotions that people experience during interactions.

Subsequent to these developments, Randall Collins (2004) formulated his interaction ritual theory by drawing on Durkheim's work on totemic rituals that was extended by Goffman (1964/2013; 1967)] into everyday focused encounters. Based on interaction ritual theory, we experience different levels or intensities of emotional energy during face-to-face interactions. Emotional energy is considered to be a feeling of confidence to take action and a boldness that one experiences when they are charged up from the collective effervescence generated during group gatherings that reach high levels of intensity.

There is a growing body of research applying the sociology of emotion to understanding the learning experiences of students during classroom interactions with teachers and other students (for example, Milne & Otieno, 2007; Olitsky, 2007; Tobin, et al., 2013; Zembylas, 2002). These studies show that learning subjects like science can be understood in terms of classroom interaction rituals that generate emotional energy and collective states of emotional arousal like emotional climate.

Apart from interaction ritual traditions of the sociology of emotion, other approaches have been classed into one of 6 other categories (Turner, 2009) including:
  1. evolutionary/biological theories,
  2. symbolic interactionist theories,
  3. dramaturgical theories,
  4. ritual theories,
  5. power and status theories,
  6. stratification theories, and
  7. exchange theories.
This list provides a general overview of different traditions in the sociology of emotion that sometimes conceptualise emotion in different ways and at other times in complementary ways. Many of these different approaches were synthesized by Turner (2007) in his sociological theory of human emotions in an attempt to produce one comprehensive sociological account that draws on developments from many of the above traditions.

Psychotherapy and regulation

Emotion regulation refers to the cognitive and behavioral strategies people use to influence their own emotional experience. For example, a behavioral strategy in which one avoids a situation to avoid unwanted emotions (trying not to think about the situation, doing distracting activities, etc.). Depending on the particular school's general emphasis on either cognitive components of emotion, physical energy discharging, or on symbolic movement and facial expression components of emotion, different schools of psychotherapy approach the regulation of emotion differently. Cognitively oriented schools approach them via their cognitive components, such as rational emotive behavior therapy. Yet others approach emotions via symbolic movement and facial expression components (like in contemporary Gestalt therapy).

Cross-cultural research

Research on emotions reveals the strong presence of cross-cultural differences in emotional reactions and that emotional reactions are likely to be culture-specific. In strategic settings, cross-cultural research on emotions is required for understanding the psychological situation of a given population or specific actors. This implies the need to comprehend the current emotional state, mental disposition or other behavioral motivation of a target audience located in a different culture, basically founded on its national political, social, economic, and psychological peculiarities but also subject to the influence of circumstances and events.

Computer science

In the 2000s, research in computer science, engineering, psychology and neuroscience has been aimed at developing devices that recognize human affect display and model emotions. In computer science, affective computing is a branch of the study and development of artificial intelligence that deals with the design of systems and devices that can recognize, interpret, and process human emotions. It is an interdisciplinary field spanning computer sciences, psychology, and cognitive science. While the origins of the field may be traced as far back as to early philosophical enquiries into emotion, the more modern branch of computer science originated with Rosalind Picard's 1995 paper on affective computing. Detecting emotional information begins with passive sensors which capture data about the user's physical state or behavior without interpreting the input. The data gathered is analogous to the cues humans use to perceive emotions in others. Another area within affective computing is the design of computational devices proposed to exhibit either innate emotional capabilities or that are capable of convincingly simulating emotions. Emotional speech processing recognizes the user's emotional state by analyzing speech patterns. The detection and processing of facial expression or body gestures is achieved through detectors and sensors. The pioneer F-M Facial Action Coding System 2.0 (F-M FACS 2.0)  was created in 2017 by Dr. Freitas-Magalhães, and presents about 2,000 segments in 4K, using 3D technology and automatic and real-time recognition.

Notable theorists


In the late 19th century, the most influential theorists were William James (1842–1910) and Carl Lange (1834–1900). James was an American psychologist and philosopher who wrote about educational psychology, psychology of religious experience/mysticism, and the philosophy of pragmatism. Lange was a Danish physician and psychologist. Working independently, they developed the James–Lange theory, a hypothesis on the origin and nature of emotions. The theory states that within human beings, as a response to experiences in the world, the autonomic nervous system creates physiological events such as muscular tension, a rise in heart rate, perspiration, and dryness of the mouth. Emotions, then, are feelings which come about as a result of these physiological changes, rather than being their cause.

Silvan Tomkins (1911–1991) developed the Affect theory and Script theory. The Affect theory introduced the concept of basic emotions, and was based on the idea that the dominance of the emotion, which he called the affected system, was the motivating force in human life.

Some of the most influential theorists on emotion from the 20th century have died in the last decade. They include Magda B. Arnold (1903–2002), an American psychologist who developed the appraisal theory of emotions; Richard Lazarus (1922–2002), an American psychologist who specialized in emotion and stress, especially in relation to cognition; Herbert A. Simon (1916–2001), who included emotions into decision making and artificial intelligence; Robert Plutchik (1928–2006), an American psychologist who developed a psychoevolutionary theory of emotion; Robert Zajonc (1923–2008) a Polish–American social psychologist who specialized in social and cognitive processes such as social facilitation; Robert C. Solomon (1942–2007), an American philosopher who contributed to the theories on the philosophy of emotions with books such as What Is An Emotion?: Classic and Contemporary Readings (Oxford, 2003); Peter Goldie (1946–2011), a British philosopher who specialized in ethics, aesthetics, emotion, mood and character; Nico Frijda (1927–2015), a Dutch psychologist who advanced the theory that human emotions serve to promote a tendency to undertake actions that are appropriate in the circumstances, detailed in his book The Emotions (1986); Jaak Panksepp (1943-2017), an Estonian-born American psychologist, psychobiologist, neuroscientist and pioneer in affective neuroscience.

Influential theorists who are still active include the following psychologists, neurologists, philosophers, and sociologists:

Dual diagnosis

From Wikipedia, the free encyclopedia

Dual diagnosis (also called co-occurring disorders, COD, or dual pathology) is the condition of suffering from a mental illness and a comorbid substance abuse problem. There is considerable debate surrounding the appropriateness of using a single category for a heterogeneous group of individuals with complex needs and a varied range of problems. The concept can be used broadly, for example depression and alcoholism, or it can be restricted to specify severe mental illness (e.g. psychosis, schizophrenia) and substance misuse disorder (e.g. cannabis abuse), or a person who has a milder mental illness and a drug dependency, such as panic disorder or generalized anxiety disorder and is dependent on opioids. Diagnosing a primary psychiatric illness in substance abusers is challenging as drug abuse itself often induces psychiatric symptoms, thus making it necessary to differentiate between substance induced and pre-existing mental illness.

Those with co-occurring disorders face complex challenges. They have increased rates of relapse, hospitalization, homelessness, and HIV and hepatitis C infection compared to those with either mental or substance use disorders alone.

Differentiating pre-existing and substance induced

The identification of substance-induced versus independent psychiatric symptoms or disorders has important treatment implications and often constitutes a challenge in daily clinical practice. Similar patterns of comorbidity and risk factors in individuals with substance induced disorder and those with independent non-substance induced psychiatric symptoms suggest that the two conditions may share underlying etiologic factors.

Drug abuse, including alcohol and prescription drugs, can induce symptomatology which resembles mental illness, which can make it difficult to differentiate between substance induced psychiatric syndromes and pre-existing mental health problems. More often than not psychiatric disorders among drug or alcohol abusers disappear with prolonged abstinence. Substance induced psychiatric symptoms can occur both in the intoxicated state and also during the withdrawal state. In some cases these substance induced psychiatric disorders can persist long after detoxification, such as prolonged psychosis or depression after amphetamine or cocaine abuse. Abuse of hallucinogens can trigger delusional and other psychotic phenomena long after cessation of use and cannabis may trigger panic attacks during intoxication and with use it may cause a state similar to dysthymia. Severe anxiety and depression are commonly induced by sustained alcohol abuse which in most cases abates with prolonged abstinence. Even moderate sustained use of alcohol may increase anxiety and depression levels in some individuals. In most cases these drug induced psychiatric disorders fade away with prolonged abstinence. A protracted withdrawal syndrome can also occur with psychiatric and other symptoms persisting for months after cessation of use. Among the currently prevalent medications, benzodiazepines are the most notable drug for inducing prolonged withdrawal effects with symptoms sometimes persisting for years after cessation of use.

Prospective epidemiological studies do not support the hypotheses that comorbidity of substance use disorders with other psychiatric illnesses is primarily a consequence of substance abuse or dependence or that increasing comorbidity is largely attributable to increasing use of substances. Yet emphasis is often on the effects of substances on the brain creating the impression that dual disorders are a natural consequence of these substances. However addictive drugs or exposure to gambling will not lead to addictive behaviors or drug dependence in most individuals but only in vulnerable ones, although, according to some researchers, neuroadaptation or regulation of neuronal plasticity, and molecular changes, may alter gene expression in some cases and subsequently lead to substance use disorders.

Research instruments are also often insufficiently sensitive to discriminate between independent, true dual pathology, and substance-induced symptoms. Structured instruments, as Global Appraisal of Individual Needs - Short Screener-GAIN-SS and Psychiatric Research Interview for Substance and Mental Disorders for DSM-IV-PRISM, have been developed to increase the diagnostic validity. While structured instruments can help organize diagnostic information, clinicians must still make judgments on the origin of symptoms.

Prevalence

Comorbidity of addictive disorders and other psychiatric disorders, i.e., dual disorders, is very common and a large body of literature has accumulated demonstrating that mental disorders are strongly associated with substance use disorders. The 2011 USA National Survey on Drug Use and Health found that 17.5% of adults with a mental illness had a co-occurring substance use disorder; this works out to 7.98 million people. Estimates of co-occurring disorders in Canada are even higher, with an estimated 40-60% of adults with a severe and persistent mental illness experiencing a substance use disorder in their lifetime.

A study by Kessler et al. in the United States attempting to assess the prevalence of dual diagnosis found that 47% of clients with schizophrenia had a substance misuse disorder at some time in their life, and the chances of developing a substance misuse disorder was significantly higher among patients suffering from a psychotic illness than in those without a psychotic illness.

Another study looked at the extent of substance misuse in a group of 187 chronically mentally ill patients living in the community. According to the clinician's ratings, around a third of the sample used alcohol, street drugs, or both during the six months before evaluation.

Further UK studies have shown slightly more moderate rates of substance misuse among mentally ill individuals. One study found that individuals suffering from schizophrenia showed just a 7% prevalence of problematic drug use in the year prior to being interviewed and 21% reported problematic use some time before that.

Wright and colleagues identified individuals with psychotic illnesses who had been in contact with services in the London borough of Croydon over the previous 6 months. Cases of alcohol or substance misuse and dependence were identified through standardized interviews with clients and keyworkers. Results showed that prevalence rates of dual diagnosis were 33% for the use of any substance, 20% for alcohol misuse only and 5% for drug misuse only. A lifetime history of any illicit drug use was observed in 35% of the sample.

Diagnosis

Substance use disorders can be confused with other psychiatric disorders. There are diagnoses for substance-induced mood disorders and substance-induced anxiety disorders and thus such overlap can be complicated. For this reason, the DSM-IV advises that diagnoses of primary psychiatric disorders not be made in the absence of sobriety (of duration sufficient to allow for any substance-induced post-acute-withdrawal symptoms to dissipate) up to 1 year.

Treatment

Only a small proportion of those with co-occurring disorders actually receive treatment for both disorders. Therefore, it was argued that a new approach is needed to enable clinicians, researchers and managers to offer adequate assessment and evidence-based treatments to patients with dual pathology, who cannot be adequately and efficiently managed by cross-referral between psychiatric and addiction services as currently configured and resourced. In 2011, it was estimated that only 12.4% of American adults with co-occurring disorders were receiving both mental health and addictions treatment. Clients with co-occurring disorders face challenges accessing treatment, as they may be excluded from mental health services if they admit to a substance abuse problem, and vice versa.

There are multiple approaches to treating concurrent disorders. Partial treatment involves treating only the disorder that is considered primary. Sequential treatment involves treating the primary disorder first, and then treating the secondary disorder after the primary disorder has been stabilized. Parallel treatment involves the client receiving mental health services from one provider, and addictions services from another.

Integrated treatment involves a seamless blending of interventions into a single coherent treatment package developed with a consistent philosophy and approach among care providers. With this approach, both disorders are considered primary. Integrated treatment can improve accessibility, service individualization, engagement in treatment, treatment compliance, mental health symptoms, and overall outcomes. The Substance Abuse and Mental Health Services Administration in the United States describes integrated treatment as being in the best interests or clients, programs, funders, and systems. Green suggested that treatment should be integrated, and a collaborative process between the treatment team and the patient. Furthermore, recovery should to be viewed as a marathon rather than a sprint, and methods and outcome goals should be explicit.

Although many patients may reject medications as antithetical to substance-abuse recovery and side effects, they can be useful to reduce paranoia, anxiety, and craving. Medications that have proven effective include opioid replacement therapies, such as lifelong maintenance on methadone or buprenorphine, to minimize risk of relapse, fatality, and legal trouble amongst opioid addicts, as well as helping with cravings, baclofen for alcoholics, opioid addicts, cocaine addicts, and amphetamine addicts, to help eliminate drug cravings, and clozapine, the first atypical antipsychotic, which appears to reduce illicit drug use amongst stimulant addicts. Clozapine can cause respiratory arrest when combined with alcohol, benzodiazepines, or opioids, so it is not recommended to use in these groups.

Theories of dual diagnosis

There are a number of theories that explain the relationship between mental illness and substance abuse.

Causality

The causality theory suggests that certain types of substance abuse may causally lead to mental illness.

There is strong evidence that using cannabis can produce psychotic and affective experiences. When it comes to persisting effects, there is a clear increase in incidence of psychotic outcomes in people who had used cannabis, even when they had used it only once. More frequent use of cannabis strongly augmented the risk for psychosis. The evidence for affective outcomes is less strong. However, this connection between cannabis and psychosis does not prove that cannabis causes psychotic disorders. The causality theory for cannabis has been challenged as despite explosive increases in cannabis consumption over the past 40 years in western society, the rate of schizophrenia (and psychosis in general) has remained relatively stable.

Attention-deficit hyperactivity disorder

One in four people who have a substance use disorder also have attention-deficit hyperactivity disorder, which makes the treatment of both conditions more difficult. ADHD is associated with an increased craving for drugs. Having ADHD makes it more likely that an individual will initiate substance misuse at a younger age than their peers. They are also more likely to have a poorer outcome, such as longer time to remission, and increased psychiatric complications from substance misuse. While generally stimulant medications do not seem to worsen substance misuse, they are known to be abused in some cases. Psychosocial therapy and/or nonstimulant medications and extended release stimulants are ADHD treatment options that reduce these risks.

Autism spectrum disorder

Unlike ADHD, which significantly increases the risk of substance use disorder, autism spectrum disorder has the opposite effect of significantly reducing the risk of substance abuse. This is because introversion, inhibition and lack of sensation seeking personality traits, which are typical of autism spectrum disorder, protect against substance abuse and thus substance abuse levels are low in individuals who are on the autism spectrum. However, certain forms of substance abuse, especially alcohol abuse, can cause or worsen certain neuropsychological symptoms which are common to autism spectrum disorder, such as impaired social skills due to the neurotoxic effects of alcohol on the brain, especially the prefrontal cortex area of the brain. The social skills that are impaired by alcohol abuse include impairments in perceiving facial emotions, prosody perception problems and theory of mind deficits; the ability to understand humour is also impaired in alcohol abusers.

Gambling

The inclusion of behavioral addictions like pathological gambling must change our way of understanding and dealing with addictions. Pathological (disordered) gambling has commonalities in clinical expression, etiology, comorbidity, physiology and treatment with substance use disorders (DSM-5). A challenge is to understand the development of compulsivity at a neurochemical level not only for drugs.

Past exposure to psychiatric medications theory

The past exposure theory suggests that exposure to psychiatric medication alters neural synapses, introducing an imbalance that was not previously present. Discontinuation of the drug is expected to result in symptoms of psychiatric illness which resolve once the drug is restarted. This theory suggests that while it may appear that the medication is working, it is only treating a disorder caused by the medication itself. New exposure to psychiatric medication may lead to heightened sensitivity to the effects of drugs and alcohol, which has a deteriorating effect on the patient.

Self-medication theory

The self-medication theory suggests that people with severe mental illnesses misuse substances in order to relieve a specific set of symptoms and counter the negative side-effects of antipsychotic medication.

Khantizan proposes that substances are not randomly chosen, but are specifically selected for their effects. For example, using stimulants such as nicotine or amphetamines can be used to combat the sedation that can be caused by higher doses of certain types of antipsychotic medication. Conversely, some people taking medications with a stimulant effect such as the SNRI antidepressants Effexor (venlafaxine) or Wellbutrin (bupropion) may seek out benzodiazepines or opioid narcotics to counter the anxiety and insomnia that such medications sometimes evoke.

Some studies show that nicotine administration can be effective for reducing motor side-effects of antipsychotics, with both bradykinesia (stiff muscles) and dyskinesia(involuntary movement) being prevented.

Alleviation of dysphoria theory

The alleviation of dysphoria theory suggests that people with severe mental illness commonly have a negative self-image, which makes them vulnerable to using psychoactive substances to alleviate these feelings. Despite the existence of a wide range of dysphoric feelings (anxiety, depression, boredom, and loneliness), the literature on self-reported reasons for use seems to lend support for the experience of these feelings being the primary motivator for drug and alcohol misuse.

Multiple risk factor theory

Another theory is that there may be shared risk factors that can lead to both substance abuse and mental illness. Mueser hypothesizes that these may include factors such as social isolation, poverty, lack of structured daily activity, lack of adult role responsibility, living in areas with high drug availability, and association with people who already misuse drugs.

Other evidence suggests that traumatic life events, such as sexual abuse, are associated with the development of psychiatric problems and substance abuse.

The supersensitivity theory

The supersensitivity theory proposes that certain individuals who have severe mental illness also have biological and psychological vulnerabilities, caused by genetic and early environmental life events. These interact with stressful life events and can result in either a psychiatric disorder or trigger a relapse into an existing illness. The theory states that although anti-psychotic medication can reduce the vulnerability, substance abuse may increase it, causing the individual to be more likely to experience negative consequences from using relatively small amounts of substances. These individuals, therefore, are "supersensitive" to the effects of certain substances, and individuals with psychotic illness such as schizophrenia may be less capable of sustaining moderate substance use over time without experiencing negative symptoms.

Although there are limitations in the research studies conducted in this area, namely that most have focused primarily on schizophrenia, this theory provides an explanation of why relatively low levels of substance misuse often result in negative consequences for individuals with severe mental illness.

Avoiding categorical diagnosis

Current nosological approach does not provide a framework for internal (sub-threshold symptoms) or external (comorbidity) heterogeneity of the different diagnostic categories. The prevailing "Neo-Kraepelinian" diagnostic system solely accounts for a categorical diagnosis, therefore not allowing for the possibility of dual diagnosis. There has been substantial criticism to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), due to problems of diagnostic overlap, lack of clear boundaries between normality and disease, a failure to take into account findings from novel research and the lack of diagnostic stability over time.

History

The traditional method for treating patients suffering from dual diagnosis was a parallel treatment program. In this format, patients received mental health services from one clinician while addressing their substance abuse with a separate clinician. However, researchers found that parallel treatments were ineffective, suggesting a need to integrate the services addressing mental health with those addressing substance abuse.

During the mid-1980s, a number of initiatives began to combine mental health and substance abuse services in an attempt to meet this need. These programs worked to shift the method of treatment for substance abuse from a confrontational approach to a supportive one. They also introduced new methods to motivate clients and worked with them to develop long-term goals for their care. Although the studies conducted by these initiatives did not have control groups, their results were promising and became the basis for more rigorous efforts to study and develop models of integrated treatment.

Can Science Fiction Save the World?

James Gunn, the last surviving author of the genre’s Golden Age, believes it can help, anyway.

Can Science Fiction Save the World?

There was once a time when robots roamed the surface of Mercury, when a shape-shifting alien emerged from the ice of Antarctica, and when a galactic empire of 25 million planets spanned the Milky Way. It was called the “Golden Age” of science fiction, the period from the late 1930s to the late 1940s, when pioneering authors such as Isaac Asimov and Robert A. Heinlein wrote their first mind-bending stories. And though newer literary movements have mutated sci-fi’s DNA since then, the last surviving storyteller of the Golden Age—95-year-old James Gunn—is still writing.

A longtime resident of Lawrence, Kansas, Gunn started writing short stories in 1948 for the panoply of magazines that catered to science-fiction fans in the postwar years, including Amazing Stories, Astounding Science Fiction (now known as Analog), and Galaxy. Over the following decades he authored dozens of books; his 1962 novel The Immortals was turned into a television series, and his 1972 masterpiece The Listeners inspired many researchers to join the search for extraterrestrial intelligence. But perhaps Gunn’s greatest accomplishment was making science fiction more respectable. As a professor at the University of Kansas, he established a center for studying the genre and wrote several books that recounted its history.

Gunn’s motto is, “Let’s save the world through science fiction,” and he takes it seriously. Many of the Golden Age writers, he says, had a missionary impulse. By portraying interstellar spaceflight and strange aliens and powerful machines, they tried to steer us past the hazards of the mid-20th century and offer hope for a brighter future. During the 1940s Gunn found inspiration from what he calls “the great foursome” of Golden Age sci-fi: Asimov, Heinlein, Theodore Sturgeon and A.E. van Vogt. “They covered the whole spectrum of science fiction at the time,” Gunn says. “I learned from all of them.”

The man who published all these authors and ushered in the Golden Age was John W. Campbell, who became editor of Astounding Science Fiction in 1937. (He also wrote Who Goes There?—the novella about the alien in Antarctica—which became the classic sci-fi film The Thing From Another World.) Campbell urged the magazine’s writers to move away from the silly Buck Rogers adventures that had previously dominated the genre and concentrate instead on the intelligent exploration of futuristic ideas. Several of Heinlein’s novels were serialized in Astounding, and Asimov’s stories about robots and galactic empires were later collected in I, Robot and the Foundation series. Gunn’s earliest stories were in the same vein; some of them focused on the challenge of communication between alien species, a theme he returned to in The Listener.

In the 1950s, many of the sci-fi magazines went belly-up, and the best writers in the genre turned to investigating the sociology of the future, as Ray Bradbury did in Fahrenheit 451 and Gunn did in The Joy Makers, which imagines a society geared to maximize human happiness. In the 1960s and 1970s, so-called New Wave writers such as Harlan Ellison and Ursula K. Le Guin pushed science fiction into more literary and experimental terrain. After 1980 the readership of the remaining sci-fi magazines declined, but there was a big jump in the number of science fiction books published each year. “When I started, we could read everything that was published,” Gunn says. “Now the field has become much larger and far more diverse.”

Through it all, Gunn kept churning out novels, short-story collections, anthologies, and histories. Last year, Tor Books published the third novel in his Transcendental trilogy, which features a spaceship called the Geoffrey and a group of human and alien travelers who tell each other stories, like the pilgrims in Chaucer’s Canterbury Tales. Gunn says the most important new sci-fi trend is the rise of so many great women writers, which he believes is changing the genre for the better. “Science fiction makes people more willing to think boldly and broadly,” Gunn says. “It’s good for the human species.”

Alcoholism in family systems

From Wikipedia, the free encyclopedia
 

Alcoholism in family systems refers to the conditions in families that enable alcoholism, and the effects of alcoholic behavior by one or more family members on the rest of the family. Mental health professionals are increasingly considering alcoholism and addiction as diseases that flourish in and are enabled by family systems. Family members react to the alcoholic with particular behavioral patterns. They may enable the addiction to continue by shielding the addict from the negative consequences of their actions. Such behaviors are referred to as codependence. In this way, the alcoholic is said to suffer from the disease of addiction, whereas the family members suffer from the disease of codependence. While it is recognized that addiction is a family disease, affecting the entire family system, "the family is often ignored and neglected in the treatment of addictive disease." Each individual member is affected and should receive treatment for their own benefit and healing, but in addition to benefitting the individuals themselves, this also helps to better support the addict/alcoholic in his/her recovery process. "The chances of recovery are greatly reduced unless the co-dependents are willing to accept their role in the addictive process and submit to treatment themselves." "Co-dependents are mutually dependent on the addict to fulfill some need of their own."  For example, if the "Chief Enabler" (the main enabler in the family) will often turn a blind eye to the addict's drug/alcohol use as this allows for the enabler to continue to play the victim and/or martyr role, while allowing the addict to continue his/her own destructive behavior. Therefore, "the behavior of each reinforces and maintains the other, while also raising the costs and emotional consequences for both."

Alcoholism is one of the leading causes of a dysfunctional family. "About one-fourth of the U.S. population is a member of family that is affected by an addictive disorder in a first-degree relative."  As of 2001, there were an estimated 26.8 million children of alcoholics (COAs) in the United States, with as many as 11 million of them under the age of 18. Children of addicts have an increased suicide rate and on average have total health care costs 32 percent greater than children of nonalcoholic families.

According to the American Psychiatric Association, physicians stated three criteria to diagnose this disease: (1) physiological problems, such as hand tremors and blackouts, (2) psychological problems, such as excessive desire to drink, and (3) behavioral problems that disrupt social interaction or work performance.

Adults from alcoholic families experience higher levels of state and trait anxiety and lower levels of differentiation of self than adults raised in non-alcoholic families. Additionally, adult children of alcoholics have lower self-esteem, excessive feelings of responsibility, difficulties reaching out, higher incidence of depression, and increased likelihood of becoming alcoholics.

Parental alcoholism may affect the fetus even before a child is born. In pregnant women, alcohol is carried to all of the mother’s organs and tissues, including the placenta, where it easily crosses through the membrane separating the maternal and fetal blood systems. When a pregnant woman drinks an alcoholic beverage, the concentration of alcohol in her unborn baby’s bloodstream is the same level as her own. A pregnant woman who consumes alcohol during her pregnancy may give birth to a baby with Fetal Alcohol Syndrome (FAS).[11] FAS (fetal alcohol syndrome) is known to produce children with damage to the central nervous system, general growth and facial features. The prevalence of this class of disorder is thought to be between 2–5 per 1000.

Alcoholism does not have uniform effects on all families. The levels of dysfunction and resiliency of the non-alcoholic adults are important factors in effects on children in the family. Children of untreated alcoholics score lower on measures of family cohesion, intellectual-cultural orientation, active-recreational orientation, and independence. They have higher levels of conflict within the family, and many experience other family members as distant and non-communicative. In families with untreated alcoholics, the cumulative effect of the family dysfunction may affect the children's ability to grow in developmentally healthy ways.

Family roles

The role of the "Chief Enabler" is typically the spouse, significant other, parent, or eldest child of the alcoholic/addict. This person demonstrates "a strong tendency to avoid any confrontation of the addictive behavior and a subconscious effort to actively perpetuate the addiction." The "Chief Enabler" also often doubles as the "Responsible One," or "Family Hero" another role assumed by family members of the alcoholic/addict. Both the "Chief Enabler" and "Responsible One" (aka "Model Child") will take "over [the alcoholic/addict's] roles and responsibilities." For example, a parent might pay for expenses and take over responsibilities (i.e. car payments, the raising of a grandchild, provide room and board, etc.), while a child may provide care for their siblings, become the "peace keeper" in the home, take on all the chores and cooking, etc. A spouse or significant other may overcompensate by providing all the care to the children, being the sole financial contributor to the household, covering up or hiding the addiction from others, etc. This role often receives the most praise from non-family members, causing the individual to struggle to see that it is an unhealthy role which contributes to the addict/alcoholic's disease as well as the family's disfunction.

Another role is that of the "Problem Child" or "Scapegoat." This person "may be the only [one] clearly seen as having a problem" outside of the actual addict/alcoholic. These children (or adult children of the alcoholic(s)) "gets blamed for everything; they have problems at school, exhibit negative behavior, and often develope drug or alcohol problems as a way to act out. Their behavior demands whatever attention is available from parents and siblings." This often "takes the focus off the parental alcohol problem," and the child can be the "scapegoat" under the myth that his/her behavior fuels the parent's drinking/using. However, this child draws attention from outsiders which may contribute to the recognition of the family alcohol problem by outsiders.

The "Lost Child" role is identified in this system through children that are "withdrawn, 'spaced-out,' and disconnected from the life and emotions around them." They often avoid "any emotionally confronting issues, [and so are] unable to form close friendships or intimate bonds with others."

Other children, "trivialize things by minimizing all serious issues as an avoidance strategy [and] are well liked and easy to befriend but are usually superficial in all relationships, including those with their own family members." These children are known as the "Mascot" or "Family Clown." 

Prevalence

Based on the number of children with parents meeting the DSM-V criteria for alcohol abuse or alcohol dependence, in 1996 there were an estimated 26.8 million children of alcoholics (COAs) in the United States of which 11 million were under the age of 18. As of 1988, it was estimated that 76 million Americans, about 43% of the U.S. adult population, have been exposed to alcoholism or problem drinking in the family, either having grown up with an alcoholic, having an alcoholic blood relative, or marrying an alcoholic. While growing up, nearly one in five adult Americans (18%) lived with an alcoholic. In 1992, it was estimated that one in eight adult American drinkers were alcoholics or experienced problems as consequences of their alcohol use.

Familiality

Children of alcoholics (COAs) are more susceptible to alcoholism and other drug abuse than children of non-alcoholics. Children of alcoholics are four times more likely than non-COAs to develop alcoholism. Both genetic and environmental factors influence the development of alcoholism in COAs.

COAs perceptions of their parents drinking habits influence their own future drinking patterns and are developed at an early age. Alcohol related expectancies are correlated with parental alcoholism and alcohol abuse among their offspring. Problem solving discussions in families with an alcoholic parent contained more negative family interactions than in families with non-alcoholics parents. Several factors related to parental alcoholism influence COA substance abuse including stress, negative affect and decreased parental monitoring. Impaired parental monitoring and negative affect correlate with COAs associating with peers that support drug use.

After drinking alcohol, sons of alcoholics experience more of the physiological changes associated with pleasurable effects compared with sons of non-alcoholics, although only immediately after drinking.

Compared with non-alcoholic families, alcoholic families demonstrate poorer problem-solving abilities, both among the parents and within the family as a whole. These communication problems many contribute to the escalation of conflicts in alcoholic families. COAs are more likely than non-COAs to be aggressive, impulsive, and engage in disruptive and sensation seeking behaviors. Alcohol addiction is a complex disease that results from a variety of genetic, social, and environmental influences. Alcoholism affected approximately 4.65 percent of the U.S. population in 2001–2002, producing severe economic, social, and medical ramifications (Grant 2004). Researchers estimate that between 50 and 60 percent of alcoholism risk is determined by genetics (Goldman and Bergen 1998; McGue 1999).This strong genetic component has sparked numerous linkage and association studies investigating the roles of chromosomal regions and genetic variants in determining alcoholism susceptibility.

Marital relationships

Alcoholism usually has strong negative effects on marital relationships. Separated and divorced men and women were three times as likely as married men and women to say they had been married to an alcoholic or problem drinker. Almost two-thirds of separated and divorced women, and almost half of separated or divorced men under age 46 have been exposed to alcoholism in the family at some time.

Exposure was higher among women (46.2 percent) than among men (38.9 percent) and declined with age. Exposure to alcoholism in the family was strongly related to marital status, independent of age: 55.5 percent of separated or divorced adults had been exposed to alcoholism in some family member, compared with 43.5 percent of married, 38.5 percent of never married, and 35.5 percent of widowed persons. Nearly 38 percent of separated or divorced women had been married to an alcoholic, but only about 12 percent of currently married women were married to an alcoholic.

Children

Prevalence of abuse

Over one million children yearly are confirmed as victims of child abuse and neglect by state child protective service agencies. Substance abuse is one of the two largest problems affecting families in the United States, being a factor in nearly four-fifths of reported cases. Alcoholism is more prevalent among child abusing parents. Alcoholism is more strongly correlated to child abuse than depression and other disorders.

Adoption plays only a slight role in alcoholism in the family. Studies were done comparing children who were born into a family with an alcoholic parent and raised by adoptive (non-alcoholic) parents as compared to children born to non-alcoholic parents and raised by adopted alcoholic parents. The results (in US and Scandinavian studies) were that those adopted children born of an alcoholic parent (and adopted by non-alcoholic parents ) developed alcoholism at higher rates as adults.

Correlates

Children of alcoholics exhibit symptoms of depression and anxiety more than children of non-alcoholics. COAs have lower self-esteem than non-COAs from childhood through young adulthood. Children of alcoholics show more symptoms of anxiety, depression, and externalizing behavior disorders than non-COAs. Some of these symptoms include crying, lack of friends, fear of going to school, nightmares, perfectionism, hoarding, and excessive self-consciousness.

Many children of alcoholics score lower on tests measuring cognitive and verbal skills than non-COAs. Lacking requisite skills to express themselves can impact academic performance, relationships, and job interviews. The lack of these skills do not, however, imply that COAs are intellectually impaired. COAs are also shown to have difficulty with abstraction and conceptual reasoning, both of which play an important role in problem-solving academically and otherwise.

In her book Adult Children of Alcoholics, Janet G. Woititz describes numerous traits common among adults who had an alcoholic parent. Although not necessarily universal or comprehensive, these traits constitute an adult children of alcoholics syndrome (cf. the work of Wayne Kritsberg).

Coping Mechanism

Suggested practices to mitigate the impact of parental alcoholism on the development of their children include:
  • Maintaining healthy family traditions and practices, such as vacations, mealtimes, and holidays
  • Encouraging COAs to develop consistent, stable, relationships with significant others outside of the family.
  • Planning non-drinking activities to compete with alcoholic behaviour and tendencies.

Resilience

Professor and psychiatric Dieter J. Meyerhoff state that the negative effects of alcohol on the body and on health are undeniable, but we should not forget the most important unit in our society that this is affects the family and the children. The family is the main institution in which the child should feel safe and have moral values. If a good starting point is given, it is less likely that when a child becomes an adult, has a mental disorder or is addicted to drugs or alcohol. According to the American Academy of Child and Adolescent Psychiatry (AACAP) children are in a unique position when their parents abuse alcohol. The behavior of a parent is the essence of the problem, because such children do not have and do not receive support from their own family. Seeing changes from happy to angry parents, the children begin to think that they are the reason for these changes. Self-accusation, guilt, frustration, anger arises because the child is trying to understand why this behavior is occurs. Dependence on alcohol has a huge harm in childhood and adolescent psychology in a family environment. Psychologists Michelle L. Kelley and Keith Klostermann describe the effects of parental alcoholism on children, and describe the development and behavior of these children. Alcoholic children often face problems such as behavioral disorders, oppression, crime and attention deficit disorder, and there is a higher risk of internal behavior, such as depression and anxiety. Therefore, they are drinking earlier, drinking alcohol more often and are less likely to grow from moderate to severe alcohol consumption. Young people with parental abuse and parental violence are likely to live in large crime areas, which may have a negative impact on the quality of schools and increase the impact of violence in the area. Paternity alcoholism and the general parental verbal and physical spirit of violence witnessed the fears of children and the internalization of symptoms, greater likelihood of child aggression and emotional misconduct. Research on alcoholism within families has leaned towards exploring issues that are wrong in the community rather than potential strengths or positives. When researchers conduct research that helps communities, it can be easier for community members to identify with the positives and work towards a path of resilience. Flawed research design in adult children of alcoholics (ACOA) research showed ACOAs were psychologically damaged. Some flawed research designs include using ACOAs as part of the control group and comparing them to other ACOAs within the same study. This may have caused some limitations in the study that were not listed. When comparing ACOAs to other ACOAs, it is difficult to interpret accurate results that show certain behaviors in the group studied. Research that has been conducted more recently has used control groups with non-ACOAs to see whether the behaviors align with prior research. This research has shown that behaviors were similar between non-ACOAs and ACOAs. An 18-year-long study compared children of alcoholics (COA) to other COAs. In failing to use non-COAs as controls, we miss an opportunity to see if the negative aspects of a person are related to having an alcoholic parent, or are they just simply a fact of life. For example, in Werner’s study, he found that 30% of COAs were committing serious delinquencies. This data would have been more usable if they had viewed the percentage of those committing crimes when compared to non-ACOAs. In a study conducted in a midwestern university, researchers found that there was no significant difference between ACOA and non-ACOA students. One of the main differences was the student’s views on how they connect their past experiences with their current social-emotional functioning. Students who were ACOAs did not demonstrate issues with their perspective on their interpersonal issues any more than the non-ACA students. However, this study did show that there were other underlying problems in the family structure that may attribute to the perception of not being well adjusted in life.

Due to the flawed research that has been conducted in the past, many stereotypes have followed ACOAs. ACOAs have been identified as having a variety of emotional and behavioral problems, such as sleep problems, aggression and lowered self-esteem. When it comes to being a COA or ACOA, there is still hope. Results showed that a supportive and loving relationship with one of the parents can counterbalance the possible negative effects of the relationship with the alcoholic parent. When there is one alcoholic parent in the household, it helps if the child relies on other family members for support. It may be the second parent, siblings or members of the extended family. Having other supportive family members can help the child feel like s/he is not alone. Younger generations of ACOAs scored more positively, in terms of coping mechanisms. This may be due to fact that alcoholism is seen more as an illness nowadays, rather than a moral defect. There has been less victim blaming of alcoholism on parent’s, because it has now been declared a disease rather than a behavioral problem. Studies show that when ACOAs use positive coping mechanisms, it is related to more positive results. When an ACOA approaches their issues, rather than avoids them, it often relates to having a positive outlook. Studies have shown that ACOAs and COAs have more compulsive behaviors that may cause the need for higher achievement. Some ACOAs have shown that the only way to survive is to fend for themselves. This causes a sense of independence that helps them become more self-reliant. Because they perceive that independence and hard work as necessary, ACOAs develop a sense of survival instinct.

Implications for Counselors

Counselors serving ACOAs need to be careful to not assume that the client’s presenting problems are due solely to the parent’s alcoholism. Exploring the ACOAs life events, such as the number of alcoholic parents, length of time the client lived with the alcoholic parent, past interventions, and the role of extended family may help in determining what the correct method of intervention may be.

Many factors can affect marital and/or parenting difficulties, but there has not been any evidence found that can link these issues specifically to ACOAs. Research has been conducted to try to identify issues that arise when someone is a COA. It has been hard to isolate these issues solely to the fact that the child’s parents are alcoholics. Other behaviors need to be studied, like dysfunctional family relationships, childhood abuse and other childhood stressors and how they may contribute to things like depression, anxiety and bad relationships in ACOAs.

Counselors serving ACOAs can also help by working on building coping mechanisms such as creating meaningful relationships with other non-alcoholic family members. Having other family members who are supportive can help the ACOA feel like they are not alone. Counselors can also provide some psycho-education on alcoholism and its effects on family members of alcoholics. Research shows that ACOAs feel less like blaming their parents for their alcoholism after learning that alcoholism is a disease, rather than a behavior.

Pregnancy

Prenatal alcohol-related effects can occur with moderate levels of alcohol consumption by non-alcoholic and alcoholic women. Cognitive performance in infants and children is not as impacted by mothers who stopped alcohol consumption early in pregnancy, even if it was resumed after giving birth.

An analysis of six-year-olds with alcohol exposure during the second-trimester of pregnancy showed lower academic performance and problems with reading, spelling, and mathematical skills. 6% of offspring from alcoholic mothers have Fetal Alcohol Syndrome (FAS). The risk an offspring born to an alcoholic mothers having FAS increases from 6% to 70% if the mother's previous child had FAS.

People diagnosed with FAS have IQs ranging from 20–105 (with a mean of 68), and demonstrate poor concentration and attention skills. FAS causes growth deficits, morphological abnormalities, mental retardation, and behavioral difficulties. Among adolescents and adults, those with FAS are more likely to have mental health problems, dropping out or be suspended from schools, problems with the law, require assisted living as an adult, and problems with maintaining employment.
