Social cognitive neuroscience

 
Social cognitive neuroscience is the scientific study of the biological processes underpinning social cognition. Specifically, it uses the tools of neuroscience to study "the mental mechanisms that create, frame, regulate, and respond to our experience of the social world". Social cognitive neuroscience uses the epistemological foundations of cognitive neuroscience, and is closely related to social neuroscience. Social cognitive neuroscience employs human neuroimaging, typically using functional magnetic resonance imaging (fMRI). Human brain stimulation techniques such as transcranial magnetic stimulation and transcranial direct-current stimulation are also used. In nonhuman animals, direct electrophysiological recordings and electrical stimulation of single cells and neuronal populations are utilized for investigating lower-level social cognitive processes.

History and methods

The first scholarly works about the neural bases of social cognition can be traced back to Phineas Gage, a man who survived a traumatic brain injury in 1849 and was extensively studied for resultant changes in social functioning and personality. In 1924, esteemed psychologist Gordon Allport wrote a chapter on the neural bases of social phenomenon in his textbook of social psychology. However, these works did not generate much activity in the decades that followed. The beginning of modern social cognitive neuroscience can be traced to Michael Gazzaniga's book, Social Brain (1985), which attributed cerebral lateralization to the peculiarities of social psychological phenomenon. Isolated pockets of social cognitive neuroscience research emerged in the late 1980s to the mid-1990s, mostly using single-unit electrophysiological recordings in nonhuman primates or neuropsychological lesion studies in humans. During this time, the closely related field of social neuroscience emerged in parallel, however it mostly focused on how social factors influenced autonomic, neuroendocrine, and immune systems. In 1996, Giacomo Rizzolatti's group made one of the most seminal discoveries in social cognitive neuroscience: the existence of mirror neurons in macaque frontoparietal cortex. The mid-1990s saw the emergence of functional positron emission tomography (PET) for humans, which enabled the neuroscientific study of abstract (and perhaps uniquely human) social cognitive functions such as theory of mind and mentalizing. However, PET is prohibitively expensive and requires the ingestion of radioactive tracers, thus limiting its adoption.

In the year 2000, the term social cognitive neuroscience was coined by Matthew Lieberman and Kevin Oschner, who are from social and cognitive psychology backgrounds, respectively. This was done to integrate and brand the isolated labs doing research on the neural bases of social cognition. Also in the year 2000, Elizabeth Phelps and colleagues published the first fMRI study on social cognition, specifically on race evaluations. The adoption of fMRI, a less expensive and noninvasive neuroimaging modality, induced explosive growth in the field. In 2001, the first academic conference on social cognitive neuroscience was held at University of California, Los Angeles. The mid-2000s saw the emergence of academic societies related to the field (Social and Affective Neuroscience Society, Society for Social Neuroscience), as well as peer-reviewed journals specialized for the field (Social Cognitive and Affective Neuroscience, Social Neuroscience). In the 2000s and beyond, labs conducting social cognitive neuroscience research proliferated throughout Europe, North America, East Asia, Australasia, and South America.

Starting in the late 2000s, the field began expand its methodological repertoire by incorporating other neuroimaging modalities (e.g. electroencephalography, magnetoencephalography, functional near-infared spectroscopy), advanced computational methods (e.g. multivariate pattern analysis, causal modeling, graph theory), and brain stimulation techniques (e.g. transcranial magnetic stimulation, transcranial direct-current stimulation, deep brain stimulation). Due to the volume and rigor of research in the field, the 2010s saw social cognitive neuroscience achieving mainstream acceptance in the wider fields of neuroscience and psychology.

Functional anatomy

Much of social cognition is primarily subserved by two dissociable macro-scale brain networks: the mirror neuron system (MNS) and default mode network (DMN). MNS is thought to represent and identify observable actions (e.g. reaching for a cup) that are used by DMN to infer unobservable mental states, traits, and intentions (e.g. thirsty). Concordantly, the activation onset of MNS has been shown to precede DMN during social cognition. However, the extent of feedforward, feedback, and recurrent processing within and between MNS and DMN is not yet well-characterized, thus it is difficult to fully dissociate the exact functions of the two networks and their nodes.

Mirror neuron system (MNS)

Mirror neurons, first discovered in macaque frontoparietal cortex, fire when actions are either performed or observed. In humans, similar sensorimotor "mirroring" responses have been found in the brain regions listed below, which are collectively referred to as MNS. The MNS is has been found to identify and represent intentional actions such as facial expressions, body language, and grasping. MNS may encode the concept of an action, not just the sensory and motor information associated with an action. As such, MNS representations have been shown to be invariant of how an action is observed (e.g. sensory modality) and how an action is performed (e.g. left versus right hand, upwards or downwards). MNS has even been found to represent actions that are described in written language.

Mechanistic theories of MNS functioning fall broadly into two camps: motor and cognitive theories. Classical motor theories claim that abstract action representations arise from simulating actions within the motor system, while newer cognitive theories propose that abstract action representations arise from the integration of multiple domains of information: perceptual, motor, semantic, and conceptual. Aside from these competing theories, there are more fundamental controversies surrounding the human MNS – even the very existence of mirror neurons in this network is debated. As such, the term "MNS" is sometimes eschewed for more functionally defined names such as "action observation network", "action identification network", and "action representation network".

Premotor cortex

The macaque premotor cortex was the location of the first discoveries of mirror neurons. The premotor cortex is associated with a diverse array of functions, encompassing low-level motor control, motor planning, sensory guidance of movement, along with higher level cognitive functions such as language processing and action comprehension. The premotor cortex has been found to contain subregions with unique cytoarchitectural properties, the significance of which is not yet fully understood. In humans, sensorimotor mirroring responses are also found throughout premotor cortex and adjacent sections of inferior frontal gyrus and supplementary motor area.

Visuospatial information is more prevalent in ventral premotor cortex than dorsal premotor cortex. In humans, sensorimotor mirroring responses extend beyond ventral premotor cortex into adjacent regions of inferior frontal gyrus, including Broca's area, an area that is critical to language processing and speech production. Action representations in inferior frontal gyrus can be evoked by language, such as action verbs, in addition to the observed and performed actions typically used as stimuli in biological motion studies. The overlap between language and action understanding processes in inferior frontal gyrus has spurred some researchers to suggest overlapping neurocomputational mechanisms between the two. Dorsal premotor cortex is strongly associated with motor preparation and guidance, such as representing multiple motor choices and deciding the final selection of action.

Intraparietal sulcus

Classical studies of action observation have found mirror neurons in macaque intraparietal sulcus. In humans, sensorimotor mirroring responses are centered around the anterior intraperietal sulcus, with responses also seen in adjacent regions such as inferior parietal lobule and superior parietal lobule. Intraparietal sulcus has been shown to more sensitive to the motor features of biological motion, relative to semantic features. Intraparietal sulcus has been shown to encode magnitude in a domain-general manner, whether it be the magnitude of a motor movement, or the magnitude of a person's social status. Intraparietal sulcus is considered a part of the dorsal visual stream, but is also thought to receive inputs from non-dorsal stream regions such as lateral occipitotemporal cortex and posterior superior temporal sulcus.

Lateral occipitotemporal cortex (LOTC)

LOTC encompasses lateral regions of the visual cortex such as V5 and extrastriate body area. Though LOTC is typically associated with visual processing, sensorimotor mirroring responses and abstract action representations are reliably found in this region. LOTC includes cortical areas that are sensitive to motion, objects, body parts, kinematics, body postures, observed movements, and semantic content in verbs. LOTC is thought to encode the fine sensorimotor details of an observed action (e.g. local kinematic and perceptual features). LOTC is also thought to bind together the different means by which a specific action can be carried out.

Default mode network (DMN)

The default mode network (DMN) is thought to process and represent abstract social information, such as mental states, traits, and intentions. Social cognitive functions such as theory of mind, mentalizing, emotion recognition, empathy, moral cognition, and social working memory consistently recruit DMN regions in human neuroimaging studies. Though the functional anatomy of these functions can differ, they often include the core DMN hubs of medial prefrontal cortex, posterior cingulate, and temporoparietal junction. Aside from social cognition, the DMN is broadly associated with internally directed cognition. The DMN has been found to be involved in memory-related processing (semantic, episodic, prospection), self-related processing (e.g. introspection), and mindwandering. Unlike studies of the mirror neuron system, task-based DMN investigations almost always use human subjects, as DMN-related social cognitive functions are rudimentary or difficult to measure in nonhumans. However, much of DMN activity occurs during rest, as DMN activation and connectivity are quickly engaged and sustained during the absence of goal-directed cognition. As such, the DMN is widely thought the subserve the "default mode" of mammalian brain function.

The interrelations between social cognition, rest, and the diverse array of DMN-related functions are not yet well understood and is a topic of active research. Social, non-social, and spontaneous processes in the DMN are thought to share at least some underlying neurocomputational mechanisms with each other.

Medial prefrontal cortex (mPFC)

Medial prefrontal cortex (mPFC) is strongly associated with abstract social cognition such as mentalizing and theory of mind. Mentalizing about others activates much of the mPFC, but dorsal mPFC appears to be more selective for information about other people, while the middle mPFC may be more selective for information about the self.

Ventral regions of mPFC, such as ventromedial prefrontal cortex and medial orbitofrontal cortex, are thought to play a critical role in the affective components of social cognition. For example, ventromedial prefrontal cortex has been found to represent affective information about other people. Ventral mPFC has been shown to be critical in the computation and representation of valence and value for many types of stimuli, not just social stimuli.

The mPFC may subserve the most abstract components of social cognition, as it is one of the most domain general brain regions, sits at the top of the cortical hierarchy, and is last to activate during DMN-related tasks.

Posterior cingulate cortex (PCC)

Abstract social cognition recruits a large area of posteromedial cortex centered around posterior cingulate cortex (PCC), but also extending into precuneus and retrosplenial cortex. The specific function of PCC in social cognition is not yet well characterized, and its role may be generalized and tightly linked with medial prefrontal cortex. One view is that PCC may help represent some visuospatial and semantic components of social cognition. Additionally, PCC may track social dynamics by facilitating bottom-up attention to behaviorally relevant sources of information in the external environment and in memory. Dorsal PCC is also linked to monitoring behaviorally relevant changes in the environment, perhaps aiding in social navigation. Outside of the social domain, PCC is associated with a very diverse array of functions, such as attention, memory, semantics, visual processing, mindwandering, consciousness, cognitive flexibility, and mediating interactions between brain networks.

Temporoparietal junction (TPJ)

The temporoparietal junction (TPJ) is thought to be critical to distinguishing between multiple agents, such as the self and other. The right TPJ is robustly activated by false belief tasks, in which subjects have to distinguish between others' beliefs and their own beliefs in a given situation. The TPJ is also recruited by the wide variety of abstract social cognitive tasks associated with the DMN. Outside of the social domain, TPJ is associated with a diverse array of functions such as attentional reorienting, target detection, contextual updating, language processing, and episodic memory retrieval. The social and non-social functions of the TPJ may share common neurocomputational mechanisms. For example, the substrates of attentional reorientation in TPJ may be used for reorienting attention between the self and others, and for attributing attention between social agents. Moreover, a common neural encoding mechanism has been found to instantiate social, temporal, and spatial distance in TPJ.

Superior temporal sulcus (STS)

Social tasks recruit areas of lateral temporal cortex centered around superior temporal sulcus (STS), but also extending to superior temporal gyrus, middle temporal gyrus, and the temporal poles. During social cognition, the anterior STS and temporal poles are strongly associated with abstract social cognition and person information, while the posterior STS is most associated with social vision and biological motion processing. The posterior STS is also thought to provide perceptual inputs to the mirror neuron system.

Other regions

There are also several brain regions that fall outside the MNS and DMN which are strongly associated with certain social cognitive functions.

Ventrolateral prefrontal cortex (VLPFC)

The ventrolateral prefrontal cortex (VLPFC) is associated with emotional and inhibitory processing. It has been found to be involved in emotion recognition from facial expressions, body language, prosody, and more. Specifically, it is thought to access semantic representations of emotional constructs during emotion recognition. Moreover, VLPFC is often recruited in empathy, mentalizing, and theory of mind tasks. VLPFC is thought to support the inhibition of self-perspective when thinking about other people.

Insula

The insula is critical to emotional processing and interoception. It has been found to be involved in emotion recognition, empathy, morality, and social pain. The anterior insula is thought to facilitate feeling the emotions of others, especially negative emotions such as vicarious pain. Lesions of the insula are associated with decreased empathy capacity. Anterior insula also activates during social pain, such as the pain caused by social rejection.

Anterior cingulate cortex (ACC)

The anterior cingulate cortex (ACC) is associated with emotional processing and error monitoring. The dorsal ACC appears to share some social cognitive functions to the anterior insula, such as facilitating feeling the emotions of others, especially negative emotions. The dorsal ACC also robustly activates during social pain, like the pain caused by being the victim of an injustice. The dorsal ACC is also associated with social evaluation, such as the detection and appraisal of social exclusion. The subgenual ACC has been found to activate for vicarious reward, and may be involved in prosocial behavior.

Fusiform face area (FFA)

The fusiform face area (FFA) is strongly associated with face processing and perceptual expertise. The FFA has been shown to process the visuospatial features of faces, and may also encode some semantic features of faces.

Social behavior

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Social_behavior
 
Social behavior is behavior among two or more organisms within the same species, and encompasses any behavior in which one member affects the other. This is due to an interaction among those members. Social behavior can be seen as similar to an exchange of goods, with the expectation that when you give, you will receive the same. This behavior can be effected by both the qualities of the individual and the environmental (situational) factors. Therefore, social behavior arises as a result of an interaction between the two—the organism and its environment. This means that, in regards to humans, social behavior can be determined by both the individual characteristics of the person, and the situation they are in.

A group of women gathered around, talking. This is an example of social behavior.
 
A major aspect of social behavior is communication, which is the basis for survival and reproduction. Social behavior is said to be determined by two different processes, that can either work together or oppose one another. The dual-systems model of reflective and impulsive determinants of social behavior came out of the realization that behavior cannot just be determined by one single factor. Instead, behavior can arise by those consciously behaving (where there is an awareness and intent), or by pure impulse. These factors that determine behavior can work in different situations and moments, and can even oppose one another. While at times one can behave with a specific goal in mind, other times they can behave without rational control, and driven by impulse instead.

There are also distinctions between different types of social behavior, such as mundane versus defensive social behavior. Mundane social behavior is a result of interactions in day-to-day life, and are behaviors learned as one is exposed to those different situations. On the other hand, defensive behavior arises out of impulse, when one is faced with conflicting desires.

The Development of Social Behavior

Social behavior constantly changes as one continues to grow and develop, reaching different stages of life. The development of behavior is deeply tied with the biological and cognitive changes one is experiencing at any given time. This creates general patterns of social behavior development in humans. Just as social behavior is influenced by both the situation and an individual's characteristics, the development of behavior is due to the combination of the two as well—the temperament of the child along with the settings they are exposed to.

Culture (parents and individuals that influence socialization in children) play a large role in the development of a child's social behavior, as the parents or caregivers are typically those who decide the settings and situations that the child is exposed to. These various settings the child is placed in (for example, the playground and classroom) form habits of interaction and behavior insomuch as the child being exposed to certain settings more frequently than others. What takes particular precedence in the influence of the setting are the people that the child must interact with—their age, sex, and at times culture.

Emotions also play a large role in the development of social behavior, as they are intertwined with the way an individual behaves. Through social interactions, emotion is understood through various verbal and nonverbal displays, and thus plays a large role in communication. Many of the processes that occur in the brain and underlay emotion often greatly correlate with the processes that are needed for social behavior as well. A major aspect of interaction is understanding how the other person thinks and feels, and being able to detect emotional states becomes necessary for individuals to effectively interact with one another and behave socially.

As the child continues to gain social information, their behavior develops accordingly. One must learn how to behave according to the interactions and people relevant to a certain setting, and therefore begin to intuitively know the appropriate form of social interaction depending on the situation. Therefore, behavior is constantly changing as required, and maturity brings this on. A child must learn to balance their own desires with those of the people they interact with, and this ability to correctly respond to contextual cues and understand the intentions and desires of another person improves with age. That being said, the individual characteristics of the child (their temperament) is important to understanding how the individual learns social behaviors and cues given to them, and this learnability is not consistent across all children.

Patterns of Development Across the Lifespan

When studying patterns of biological development across the human lifespan, there are certain patterns that are well-maintained across humans. These patterns can often correspond with social development, and biological changes lead to respective changes in interactions.

In pre and post-natal infancy, the behavior of the infant is correlated with that of the caregiver. In infancy, there is already a development of the awareness of a stranger, in which case the individual is able to identify and distinguish between people.

Come childhood, the individual begins to attend more to their peers, and communication begins to take a verbal form. One also begins to classify themselves on the basis of their gender and other qualities salient about themselves, like race and age.

When the child reaches school age, one typically becomes more aware of the structure of society in regards to gender, and how their own gender plays a role in this. They become more and more reliant on verbal forms of communication, and more likely to form groups and become aware of their own role within the group.

An adult and infant
 
By puberty, general relations among same and opposite sex individuals are much more salient, and individuals begin to behave according to the norms of these situations. With increasing awareness of their sex and stereotypes that go along with it, the individual begins to choose how much they align with these stereotypes, and behaves either according to those stereotypes or not. This is also the time that individuals more often form sexual pairs.

Once the individual reaches childrearing age, one must begin to undergo changes within the own behavior in accordance to major life-changes of a developing family. The potential new child requires the parent to modify their behavior to accommodate a new member of the family.

Come senescence and retirement, behavior is more stable as the individual has often established their social circle (whatever it may be) and is more committed to their social structure.

Neural and Biological Correlates of Social Behavior

Neural Correlates

Rhesus monkey
 
Anatomical location of the amygdala
 
With the advent of the field social cognitive neuroscience came interest in studying social behavior's correlates within the brain, to see what is happening beneath the surface as organisms act in a social manner. Although there is debate on which particular regions of the brain are responsible for social behavior, some have claimed that the paracingulate cortex is activated when one person is thinking about the motives or aims of another, a means of understanding the social world and behaving accordingly. The medial prefrontal lobe has also been seen to have activation during social cognition  Research has discovered through studies on rhesus monkeys that the amygdala, a region known for expressing fear, was activated specifically when the monkeys were faced with a social situation they had never been in before. This region of the brain was shown to be sensitive to the fear that comes with a novel social situation, inhibiting social interaction.

Another form of studying the brain regions that may be responsible for social behavior has been through looking at patients with brain injuries who have an impairment in social behavior. Lesions in the prefrontal cortex that occurred in adulthood can effect the functioning of social behavior. When these lesions or a dysfunction in the prefrontal cortex occur in infancy/early on in life, the development of proper moral and social behavior is effected and thus atypical.

Biological Correlates

A prairie vole
 
Along with neural correlates, research has investigated what happens within the body (and potentially modulates) social behavior. Vasopressin is a posterior pituitary hormone that is seen to potentially play a role in affiliation for young rats. Along with young rats, vasopressin has also been associated with paternal behavior in prairie voles. Efforts have been made to connect animal research to humans, and found that vasopressin may play a role in the social responses of males in human research.

Oxytocin has also been seen to be correlated with positive social behavior, and elevated levels have been shown to potentially help improve social behavior that may have been suppressed due to stress. Thus, targeting levels of oxytocin may play a role in interventions of disorders that deal with atypical social behavior.

Along with vasopressin, serotonin has also been inspected in relation to social behavior in humans. It was found to be associated with human feelings of social connection, and we see a drop in serotonin when one is socially isolated or has feelings of social isolation. Serotonin has also been associated with social confidence.

Affect and Social Behavior

Positive affect (emotion) has been seen to have a large impact on social behavior, particularly by inducing more helping behavior, cooperation, and sociability. Studies have shown that even subtly inducing positive affect within individuals caused greater social behavior and helping. This phenomenon, however, is not one-directional. Just as positive affect can influence social behavior, social behavior can have an influence on positive affect.

Electronic Media and Social Behavior

Social behavior has typically been seen as a changing of behaviors relevant to the situation at hand, acting appropriately with the setting one is in. However, with the advent of electronic media, people began to find themselves in situations they may have not been exposed to in everyday life. Novel situations and information presented through electronic media has formed interactions that are completely new to people. While people typically behaved in line with their setting in face-to-face interaction, the lines have become blurred when it comes to electronic media. This has led to a cascade of results, as gender norms started to merge, and people were coming in contact with information they had never been exposed to through face-to-face interaction. A political leader could no longer tailor a speech to just one audience, for their speech would be translated and heard by anyone through the media. People can no longer play drastically different roles when put in different situations, because the situations overlap more as information is more readily available. Communication flows more quickly and fluidly through media, causing behavior to merge accordingly.

An example of helping behavior
 
Media has also been shown to have an impact on promoting different types of social behavior, such as prosocial and aggressive behavior. For example, violence shown through the media has been seen to lead to more aggressive behavior in its viewers. Research has also been done investigating how media portraying positive social acts, prosocial behavior, could lead to more helping behavior in its viewers. The general learning model was established to study how this process of translating media into behavior works, and why. This model suggests a link between positive media with prosocial behavior and violent media with aggressive behavior, and posits that this is mediated by the characteristics of the individual watching along with the situation they are in. This model also presents the notion that when one is exposed to the same type of media for long periods of time, this could even lead to changes within their personality traits, as they are forming different sets of knowledge and may be behaving accordingly.

In various studies looking specifically at how video games with prosocial content effect behavior, it was shown that exposure influenced subsequent helping behavior in the video-game player.[23] The processes that underlay this effect point to prosocial thoughts being more readily available after playing a video game related to this, and thus the person playing the game is more likely to behave accordingly. These effects were not only found with video games, but also with music, as people listening to songs involving aggression and violence in the lyrics were more likely to act in an aggressive manner. Likewise, people listening to songs related to prosocial acts (relative to a song with neutral lyrics) were shown to express greater helping behaviors and more empathy afterwards. When these songs were played at restaurants, it even led to an increase in tips given (relative to those who heard neutral lyrics).

Aggressive and Violent Behavior

Aggression is an important social behavior that can have both negative consequences (in a social interaction) and adaptive consequences (adaptive in humans and other primates for survival). There are many differences in aggressive behavior, and a lot of these differences are sex-difference based.

Verbal, Coverbal, and Nonverbal Social Behavior

Verbal and Coverbal Behaviors

An example of hand gestures and facial expression accompanying speech.
 
Although most animals can communicate nonverbally, humans have the ability to communicate with both verbal and nonverbal behavior. Verbal behavior is the content one's spoken word. Verbal and nonverbal behavior intersect in what is known as coverbal behavior, which is nonverbal behavior that contribute to the meaning of verbal speech (i.e. hand gestures used to emphasize the importance of what someone is saying). Although the spoken words convey meaning in and of themselves, one cannot dismiss the coverbal behaviors that accompany the words, as they place great emphasis on the thought and importance contributing to the verbal speech. Therefore, the verbal behaviors and gestures that accompany it work together to make up a conversation. Although many have posited this idea that nonverbal behavior accompanying speech serves an important role in communication, it is important to note that not all researchers agree. However, in most literature on gestures, we see that unlike body language, gestures can accompany speech in ways that bring inner thoughts to life (often thoughts unable to be expressed verbally). Gestures (coverbal behaviors) and speech occur simultaneously, and develop along the same trajectory within children as well.

Nonverbal Behaviors

An example of a nonverbal behavior (facial expression, smile)
 
Behaviors that include any change in facial expression or body movement constitute the meaning of nonverbal behavior. Communicative nonverbal behavior include facial and body expressions that are intentionally meant to convey a message to those who are meant to receive it. Nonverbal behavior can serve a specific purpose (i.e. to convey a message), or can be more of an impulse/reflex. Paul Ekman, an influential psychologist, investigated both verbal and nonverbal behavior (and their role in communication) a great deal, emphasizing how difficult it is to empirically test such behaviors. Nonverbal cues can serve the function of conveying a message, thought, or emotion both to the person viewing the behavior and the person sending these cues.

Disorders Involving Impairments in Social Behavior

Social Anxiety Disorder

Social Anxiety Disorder is a phobic disorder characterized by a fear of being judged by others, which manifests itself as a fear of people in general. Due to this pervasive fear of embarrassing oneself in front of others, it causes those affected to avoid interactions with other people at all costs. People who classify as having Social Anxiety Disorder typically have low self-esteem due to being highly critical of themselves, and thus avoid contact for fear of being "exposed" as unlikable. Efforts to find the neural correlates associated with Social Anxiety Disorder have turned to functional neuroimaging, which has found that Social Anxiety Disorder is greatly associated with hyperactivity of the amygdala, the brain area activated during fear.

Attention Deficit Hyperactivity Disorder

ADHD is a neurodevelopmental disorder mainly identified by its symptoms of inattention, hyperactivity, and impulsivity. Hyperactivity-Impulsivity may lead to hampered social interactions, as one who displays these symptoms may be socially intrusive, unable to maintain personal space, and talk over others. The majority of children that display symptoms of ADHD also have problems with their social behavior. Although children may not identify these social problems within themselves, their caregivers, adults in their lives, and other children their age frequently report it. Children who have ADHD tend to be more frequently and quickly rejected by their peers, and their social skills tend to be less developed than those of the others in their age-group. Early social behavior difficulties within childhood can lead to further, more serious problems in adulthood (i.e. unruly behavior, problems with school, work, and potentially substance abuse). Studies have shown that while it seems as though those with ADHD have the information of social norms (according to their age) readily available, they have a hard time translating this knowledge to their own behavior.

Autism Spectrum

Autism Spectrum Disorder is a neurodevelopmental disorder that affects the functioning of social interaction and communication. People who fall on the autism spectrum scale may have difficulties in understanding social cues and the emotional states of others. Due to this, one may find it difficult to modulate behavior according to the situation, and act according to the setting's standards. Along the spectrum of autism includes Aspergers Syndrome, which contains the atypical functioning of social interaction and communication seen in autism, but without a clinically significant delay of cognitive and language abilities. Research is still being done to investigate which brain regions are involved in Autism Spectrum Disorder. In regards to abnormalities that often occur in Autism Spectrum Disorder, one who classifies as among the spectrum may have a series of symptoms, such as difficulty or inability to maintain eye-contact with another person, and communicate via face and body expression. One may have a hard time forming relationships with their peers, and have a difficult time forming mutual interests and sharing a common excitement with others. Language may be impaired to those on the low-end of the spectrum, which affects conversation and communication with others.

Learning Disability

Learning disabilities are often defined as a specific deficit in academic achievement; however, research has shown that with a learning disability can come social skill deficits as well. The National Joint Committee on Learning Disabilities now include delays in social interaction within the definition of learning disability. A growing body of research has studied the close connection between academic and social delays, and has seen that those with learning disabilities are at greater risk for experiencing social skill deficits than those who do not have an academic achievement delay. There is not enough evidence to claim that academic deficits are the cause of subsequent social delays, however, there is a strong correlation between the two.

Prosocial behavior

From Wikipedia, the free encyclopedia
 
Prosocial behavior, or intent to benefit others, is a social behavior that "benefit[s] other people or society as a whole", "such as helping, sharing, donating, co-operating, and volunteering". Obeying the rules and conforming to socially accepted behaviors (such as stopping at a "Stop" sign or paying for groceries) are also regarded as prosocial behaviors. These actions may be motivated by empathy and by concern about the welfare and rights of others, as well as for egoistic or practical concerns, such as one's social status or reputation, hope for direct or indirect reciprocity, or adherence to one's perceived system of fairness. It may also be motivated by altruism, though the existence of pure altruism is somewhat disputed, and some have argued that this falls into philosophical rather than psychological realm of debate. Evidence suggests that pro sociality is central to the well-being of social groups across a range of scales, including schools. Prosocial behavior in the classroom can have a significant impact on a student's motivation for learning and contributions to the classroom and larger community. Empathy is a strong motive in eliciting prosocial behavior, and has deep evolutionary roots.

Prosocial behavior fosters positive traits that are beneficial for children and society. It helps many beneficial functions by bettering production of any league and its organizational scale. Evolutionary psychologists use theories such as kin-selection theory and inclusive fitness as an explanation for why prosocial behavioral tendencies are passed down generationally, according to the evolutionary fitness displayed by those who engaged in prosocial acts. Encouraging prosocial behavior may also require decreasing or eliminating undesirable social behaviors.

Although the term "prosocial behavior" is often associated with developing desirable traits in children, the literature on the topic has grown since the late 1980s to include adult behaviors as well.

Origin of the term

According to the psychology researcher C. Daniel Batson, the term "was created by social scientists as an antonym for antisocial."

Reciprocity vs. altruism in motivation

The purest forms of prosocial behavior are motivated by altruism, an unselfish interest in helping another person. According to Santrock, the circumstances most likely to evoke altruism are empathy for an individual in need, or a close relationship between the benefactor and the recipient. However, many prosocial behaviors that appear altruistic are in fact motivated by the norm of reciprocity, which is the obligation to return a favor with a favor. People feel guilty when they do not reciprocate and they may feel angry when someone else does not reciprocate. Reciprocal altruism suggests that "such helping is driven by a genetic tendency". Thus some professionals argue that altruism may not exist, and is completely motivated by reciprocity. Either reciprocity or altruism may motivate many important prosocial behaviors, including sharing.

Situational and individual factors

Prosocial behavior is mediated by both situational and individual factors.

Situational factors

One of the most common situation factors is the occurrence of the bystander effect. The bystander effect is the phenomenon that an individual's likelihood of helping decreases when passive bystanders are present in a critical situation. For example, when someone drops a stack of papers on a crowded sidewalk, most people are likely to continue passing him/her by. This example can be extended to even more urgent situations, such as a car crash or natural disaster. 

The decision model of bystander intervention noted that whether or not an individual gives aid in a situation depends upon their analysis of the situation. An individual will consider whether or not the situation requires their assistance, if the assistance is the responsibility of the individual, and how to help.

This model, proposed by Latane and Darley, describes five things that must occur in order for a person to intervene:
  1. Notice the situation
  2. Construe it as an emergency.
  3. Develop feelings of responsibility.
  4. Believe they have skills to succeed.
  5. Reach a conscious decision to help.
The number of individuals present in the situation requiring help is also a mediating factor in one's decision to give aid, where the more individuals are present, the less likely it is for one particular individual to give aid due to a reduction in perceived personal responsibility. This is known as diffusion of responsibility, where the responsibility one feels for the person(s) in need is divided by the number of bystanders. Another factor that comes into play is evaluation apprehension, which simply refers to the fear of being judged by other bystanders. Finally, pluralistic ignorance may also lead to someone not intervening. This refers to relying on the reaction of others, before reacting yourself. 

Additionally, Piliavin et al., (1981) noted that individuals are likely to maximize their rewards and minimize their costs when determining whether or not to give aid in a situation – that is, that people are rationally self-motivated. Prosocial behavior is more likely to occur if the cost of helping is low (i.e. minimal time, or minimal effort), if helping would actually benefit the individual providing the help in some way, and if the rewards of providing the help are large. If it is in an individual's interest to help, they will most likely do so, especially if the cost of not providing the help is great.

People are also more likely to help those in their social group, or their "in group". With a sense of shared identity with the individual requiring assistance, the altruist is more likely to provide help, on the basis that one allocates more time and energy towards helping behavior within individuals of their own group. The labeling of another individual as a member of one's "in-group" leads to greater feelings of closeness, emotional arousal, and a heightened sense of personal responsibility for the other's welfare, all of which increase the motivation to act prosocially.

Researchers have also found that social exclusion decreases the likelihood of prosocial behavior occurring. In a series of seven experiments conducted by Twenge et al., (2007) researchers manipulated social inclusion or exclusion by telling research participants that other participants had purposefully excluded them, or that they would probably end up alone later in life. They found that this preliminary social exclusion caused prosocial behavior to drop significantly, noting that "Socially excluded people donated less money to a student fund, were unwilling to volunteer for further lab experiments, were less helpful after a mishap, and cooperated less in a mixed-motive game with another student." This effect is thought to be due to the fact that prosocial behavior, again, is motivated by a sense of responsibility in caring for and sharing resources with members of one's own group.

Individual factors

Individuals can be compelled to act prosocially based on learning and socialization during childhood. Operant conditioning and social learning positively reinforces discrete instances of prosocial behaviors. Cognitive capacities like intelligence for example, are almost always related to prosocial likings. Helping skills and a habitual motivation to help others is therefore socialized, and reinforced as children understand why helping skills should be used to help others around them.

Social and individual standards and ideals also motivate individuals to engage in prosocial behavior. Social responsibility norms, and social reciprocity norms reinforce those who act prosocially. As an example, consider the child who is positively reinforced for "sharing" during their early childhood years. When acting prosocially, individuals reinforce and maintain their positive self-images or personal ideals, as well as help to fulfill their own personal needs. The correlation between a helper's state and helping tendencies are greatly restricted to the relationship between whomever takes part in the situation.

Emotional arousal is an additional important motivator for prosocial behavior in general. Batson's (1987) empathy-altruism model examines the emotional and motivational component of prosocial behavior. Feeling empathy towards the individual needing aid increases the likelihood that the aid will be given. This empathy is called "empathetic concern" for the other individual, and is characterized by feelings of tenderness, compassion, and sympathy.

Agreeableness is thought to be the personality trait most associated with inherent prosocial motivation. Prosocial thoughts and feelings may be defined as a sense of responsibility for other individuals, and a higher likelihood of experiencing empathy ("other-oriented empathy") both affectively (emotionally) and cognitively. These prosocial thoughts and feelings correlate with dispositional empathy and dispositional agreeableness.

Other factors

In addition to situational and individualistic factors, there are some categorical characteristics that can impact prosocial behavior. Several studies have indicated a positive relationship between prosocial behavior and religion. In addition, there may be sex differences in prosocial behavior, particularly as youths move into adolescence. Research suggests that while women and men both engage in prosocial behaviors, women tend to engage in more communal and relational prosocial behaviors whereas men tend to engage in more agentic prosocial behaviors. A recent study examining workplace charitable giving looked at the role of both sex and ethnicity. Results showed that women gave significantly more than men, and Caucasians gave significantly more than minority groups. However, the percent of minority individuals in the workplace was positively associated with workplace charitable giving by minorities. Culture, sex, and religion are important factors to consider in understanding prosocial behavior on an individual and group level.

In childhood through early adolescence

Prosocial behavior in childhood often begins with questions of sharing and fairness. From age 12–18 months, children begin to display prosocial behavior in presenting and giving their toys to their parents, without promoting or being reinforced by praise. The development of prosocial behavior continues throughout the second year of life, as children begin to gain a moral understanding of the world. As obedience to societal standards becomes important, children's ability to exhibit prosocial behavior strengthens, with occurrence and diversity of these behaviors increasing with age and cognitive maturity. What is important developmentally is that the child has developed a belief that sharing is an obligatory part of a social relationship and involves a question of right and wrong. So, as children move through childhood, their reasoning changes from being hedonistic and needs-oriented to becoming more concerned with approval and more involved in complex cognitive forms of perspective taking and reciprocity reasoning. Additionally, children's prosocial behavior is typically more centered around interest in friends and concern for approval, whereas adolescents begin to develop reasoning that is more concerned with abstract principles such as guilt and positive affect.

Parents can set examples that children carry into their interactions and communication with peers, but parents are not present during all of their children's peer exchanges. The day-to-day constructions of fairness standards is done by children in collaboration and negotiation with each other. Recent research demonstrates that invoking the self using subtle linguistic cues (e.g. identifying someone as a "helper" versus labeling the action, "helping") fosters the perception that a behavior reflects identity, and increases helping, or prosocial, behaviors in children significantly across tasks.

Another study by Nantel-Vivier et al. used a multi-informant model to investigate the development of prosocial behaviour in both Canadian and Italian adolescents aged 10–15. Their findings have indicated that, in early adolescence, although empathy and moral reasoning continue to advance, the development of prosocial behaviors reaches a plateau. Theories for this change in development suggest that it is the result of more individualized and selective prosocial behaviors. During adolescence, youth begin to focus these behaviors toward their peer groups and/or affiliations.

Consistent with previous analyses, this study also found a tendency toward higher prosocial behaviors in young adolescent girls compared to their male classmates. The earlier maturation in females may be a possible explanation for this disparity. A more recent study that focused on the effects of pubertal timing found that early maturation in adolescents has a positive impact on prosocial behaviors. While their findings apply to both genders, this study found a much more pronounced effect in males. This suggests that earlier onset of puberty has a positive correlation with the development of prosocial behaviors.

In many Indigenous American communities, prosocial behavior is a valued means of learning and child rearing. Such behaviors are seen as contributing in an eagerly collaborative and flexible environment, aimed at teaching consideration, responsibility, and skills with the guidance and support of adults. Culturally valued developmental goals are integrally tied to children's participation in these contexts. It is also helpful for children to learn cultural mores in addition to individual personality development. Children learn functional life skills through real-time observation of adults and interactive participation of these learned skills within their community.

Prosocial development in school

Prosocial behavior can act as a strong motivator in education, for it provides students with a purpose beyond themselves and the classroom. This purpose beyond the self, or self-transcendence, is an innate human need to be a part of something bigger than themselves. When learning in isolation, the way Western academics are traditionally designed, students struggle to make connections to the material and its greater overarching purpose. This disconnection harms student learning, motivation, and attitudes about education.

If teachers make space for prosocial behavior in education and social learning, then they can illustrate that what students are learning will have a direct impact on the world that they live in. This would be considered a mutually constituting relationship, or a relationship in which both individuals and culture develop interdependently. In other words, what students are learning in a classroom could be intimately connected with a purpose towards a greater cause, deepening the learning itself. 

Studies by Yeager et al. test the effects of having a self-transcendent purpose for learning, with the results showing that such a purpose for learning led to fewer future college dropouts, increased high school math and science GPAs, and persistence on boring tasks. This self transcendent purpose may not only encourage persistence on boring tasks, but may help to make boring tasks more meaningful and engaging. 

A person's ideas and opinions are largely shaped by the world that they grow up in, which in turn determines what sort of change they want to instill in the world. For example: a girl who grew up in poverty becoming a social worker. The environment she grew up in gave her an awareness of the workings of poverty, motivating her to instill change in either the institutions that cause it, or help those affected by poverty. 

There aren't many opportunities to make prosocial contributions in school; which makes school feel isolated and irrelevant. By encouraging students to find a self-transcendent purpose in their learning, we enable them to enjoy their learning and make connections to community contributions.

Influence of media programming and video games on children

Studies have shown that different types of media programming may evoke prosocial behaviors in children. 

The channels aimed at younger viewers like Nickelodeon and Disney Channel had significantly more acts of altruism than the general-audience demographic channels like A&E and or TNT, according to one large-scale study. This study examined the programming of 18 different channels, including more than 2,000 entertainment shows, during a randomly selected week on television. The study revealed that nearly three quarters (73 percent) of programs contained at least one act of altruism and on average viewers saw around three acts of altruism an hour. Around one-third of those behaviors were explicitly rewarded in the plot, potentially sending the message that these acts of prosocial behavior can come with positive consequences.

Another study on the topic was conducted by University at Buffalo, Iowa State University and University of Minnesota professors. They studied children for two years for the purpose of investigating the role of media exposure on prosocial behavior for young boys and girls. The study concluded that media exposure could possibly predict outcomes related to prosocial behavior.

Other experimental research has suggested that prosocial video games may increase prosocial behavior in players although some of this work has proven difficult to replicate. However other scholars have been critical of this work for tending to falsely dichotomize video games into prosocial/violent categories despite significant overlap as well as methodological flaws in the experimental studies. For instance a study by Ferguson and Garza found that exposure to violent video games was associated with increased prosocial behavior, both on-line as well as volunteering in the real world. The authors speculated this may be due to the prosocial themes common in many violent games, as well as team oriented play in many games.

Legislation

In the United States, in an effort to get stations to air education and prosocial programming for children, the Children's Television Act was adopted in 1990. It states that channels must produce and air programming developed specifically for children as a condition to renew broadcast licenses. After discussions as to what the definition of "specifically designed for children" really means, in 1996 guidelines were passed to correct this ambiguity.

Influence of observation

People are generally much more likely to act pro-socially in a public setting rather than in a private setting. One explanation for this finding has to do with perceived status, being publicly recognized as a pro-social individual often enhance one's self-image and desirability to be considered for inclusion in social groups. Other research has shown that merely given people the "illusion" that they are being observed (e.g., by hanging up posters of "staring" human eyes) can generate significant changes in pro-social acts such as charitable giving and less littering. Pictures of human eyes trigger an involuntary neural gaze detection mechanism, which primes people to act pro-socially. There are two different forms of prosocial behaviors. Ordinary prosocial behavior requires, "situational and sociocultural demands." Extraordinary prosocial behavior doesn't include as much. This indicates that one form is used for a more selfish result while the other is not.

Influence of perception of responsibility and guilt

Guilt has long been regarded as a motivator for prosocial behavior. Extensive data from a 2012 study conducted by de Hooge, demonstrates that when a secondary individual repairs a transgressors’ damage caused to victims, the transgressors’ guilt feelings, reparative intentions, and prosocial behavior drastically diminish. Thus, reduction of guilt may have more to do with reparative actions broadly, rather than necessarily prosocial behaviors taken on by oneself.

Social media in natural disasters

Social media can also be a catalyst for prosocial behavior. One example occurred during the relief efforts in the wake of the 2011 Tōhoku earthquake and tsunami off the coast of Japan, when users turned to Facebook and Twitter to provide financial and emotional support via their social networks. Direct donations to Japanese relief were possible on The Red Cross fan page on Facebook, and via online discount sites like Groupon and LivingSocial.

Relation to mood and emotion

Mood and prosocial behavior are closely linked. People often experience the "feel good-do good" phenomena, where being in a good mood increases helping behaviors. Being in a good mood helps us to see the "good" in other people, and prolongs our own good mood. For example, mood and work behaviors have frequently been examined in research; studies show that positive mood at work is associated with more positive work-related behaviors (e.g., helping co-workers). Similarly, prosocial behaviors increase positive mood. Several studies have shown the benefits of volunteering and other prosocial behaviors on self-esteem, life satisfaction, and overall mental health. Additionally, negative mood can also impact prosocial behavior. Research has shown that guilt often leads to prosocial behaviors, whereas other negative mood states, such as fear, do not lead to the same prosocial behaviors.

A recent pilot study examined whether an intervention increasing prosocial behavior (kind acts) in young adults with social anxiety would both increase positive affect and decrease social anxiety in participants. Participants randomly assigned to a 4-week Kind Acts intervention, where individuals were instructed to engage in three kind acts each day twice a week over the 4 week period, showed both higher self-reported positive mood and increased satisfaction with relationships at the end of the intervention. This intervention demonstrates ways in which prosocial behavior may be beneficial in improving mood and mental health.

Other research suggests that cultivating positive emotions, such as gratitude, may also facilitate prosocial behavior. A study by Bartlett & DeSteno examined the ability of gratitude to shape costly prosocial behavior, demonstrating that gratitude increases efforts to assist a benefactor even when such efforts are costly (i.e., hedonically negative), and that this increase is qualitatively different from efforts given from just general positive affective state. They also show that gratitude can increase assistance provided to strangers, not just close social ties. Awe is another positive emotional state that has been closely linked to inspiring generosity and prosocial behavior. Piff et al. studied this phenomenon through experiments using economic and ethical-decision making games and explain, "When people experience awe they really want to share that experience with other people, suggesting that it has this particularly viral component to it... awe binds people together—by causing people to want to share their positive experiences collectively with one another."

Psychopathy and lack of prosocial behavior

In 1941, Hervey Cleckley described psychopathy as a disorder in which individuals often initially appear intelligent, charming, and even kind but are in fact egocentric, grandiose and impulsive. He described individuals who would, on a whim, leave their families to cross the country gambling, drinking and fighting, only to return and act as if nothing was out of the ordinary. 

Today, psychopathy is described as a personality disorder that is characterized by decreased anxiety, fear, and social closeness as well as increased impulsivity, manipulativeness, interpersonal dominance and aggression. These traits lead to numerous types of antisocial behavior including high rates of substance abuse, serial short term relationships, and various forms of criminal behavior. One common misconception about psychopathy though is that all psychopaths are serial killers or other vicious criminals. In reality, many researchers do not consider criminal behavior to be a criterion for the disorder although the role of criminality in the disorder is strongly debated. Additionally, psychopathy is being researched as a dimensional construct that is one extreme of normal range personality traits instead of a categorical disorder.

In regards to the lack of prosocial behavior in psychopathy, there are several theories that have been proposed in the literature. One theory suggests that psychopaths engage in less prosocial behavior (and conversely more antisocial behavior) because of a deficit in their ability to recognize fear in others, particularly fearful facial expressions. Because they are unable to recognize that their actions are causing another distress, they continue that behavior in order to obtain some goal that benefits them. A second theory proposes that psychopaths have a sense of "altruistic punishment" where they are willing to punish other individuals even if it means they will be harmed in some way. There has also been an evolutionary theory proposed stating that psychopaths lack of prosocial behavior is an adaptive mating strategy in that it allows them to spread more of their genes while taking less responsibility for their offspring. Finally, there is some evidence that in some situations psychopaths behavior may not be antisocial but instead it may be more utilitarian than other individuals. In a recent study, Bartels & Pizarro (2011) found that when making decisions about traditional moral dilemmas such as the trolley problem, individuals high in psychopathic traits actually make more utilitarian (and therefore more moral in some views) choices. This finding is particularly interesting because it suggests that psychopaths, who are often considered immoral or even evil, may actually make better moral decisions than non-psychopaths. The authors of this study conclude that individuals high in psychopathic traits are less influenced by their emotions and therefore make more "mathematical" decisions and choose the option that leads to the lowest number of deaths.

The theories discussed above are not intended to be a comprehensive list but instead to provide a sense of how psychopaths differ in their approach to social interactions. As with most psychological/social phenomena, it is likely a combination of these factors that lead to psychopaths lack of prosocial behavior. Further research is needed to determine the causal nature of any one of these individual deficits as well as if there is any way to help these individuals develop more prosocial patterns of behavior.

Helper's high

Psychologists have shown that helping others can produce "feel-good" neurotransmitters such as oxytocin and that, similar to any other pleasurable activity, the act of volunteering, giving and behaving pro-socially can become addictive.

Some work has been done on utilizing this principle through the concept of helper therapy, in which therapeutic benefits are gleaned from assisting others. Community health workers have been found to gain helper benefits that include positive feelings about self, a sense of belonging, valuable work experience, and access to health information and skills through their prosocial vocation, which may buffer against the various stressors inherent in this line of work.

In addition, Helper therapy may also be highly beneficial for distressed adolescents experiencing suicidal thoughts. Studies indicate that when help-seeking youth use online community forums, the help-seekers often begin to provide support for other help seekers, and develop a reciprocal prosocial community battling depression together.

Prosocial dissidence

Stefano Passini and Davide Morselli argue that groups will obey authority so long as its system, basis, and demands are viewed as legitimate. Passini and Morselli distinguish between anti-social disobedience, which they see as destructive, and prosocial disobedience, which they see as constructive. "Disobedience becomes prosocial when it is enacted for the sake of the whole society, including all its different levels and groups. In contrast, anti-social disobedience is enacted mainly in favour of one's own group, in order to attain individual rights." A main difference between anti-social and pro-social dissidence is the way that they relate to authority; anti-social dissidents reject authority and disobey its norms and laws, while pro-social dissidents understand the important roles that societal laws play in maintaining order, but also recognize and address the flaws in authoritative reasoning. Pro-social protests, if viewed in a positive manner, can increase freedoms and equality for the general public, and improve democratic institutions.

Labor market outcomes

Recent scientific research shows that individuals who volunteer have better labor market outcomes in terms of hiring opportunities and wages.
