Ego death

From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Ego_death
 
Ego death is a "complete loss of subjective self-identity". The term is used in various intertwined contexts, with related meanings. Jungian psychology uses the synonymous term psychic death, referring to a fundamental transformation of the psyche. In death and rebirth mythology, ego death is a phase of self-surrender and transition, as described by Joseph Campbell in his research on the mythology of the Hero's Journey. It is a recurrent theme in world mythology and is also used as a metaphor in some strands of contemporary western thinking.

In descriptions of drugs, the term is used synonymously with ego-loss to refer to (temporary) loss of one's sense of self due to the use of drugs. The term was used as such by Timothy Leary et al. to describe the death of the ego in the first phase of an LSD trip, in which a "complete transcendence" of the self occurs.

The concept is also used in contemporary New Age spirituality and in the modern understanding of Eastern religions to describe a permanent loss of "attachment to a separate sense of self" and self-centeredness. This conception is an influential part of Eckhart Tolle's teachings, where Ego is presented as an accumulation of thoughts and emotions, continuously identified with, which creates the idea and feeling of being a separate entity from one's self, and only by disidentifying one's consciousness from it can one truly be free from suffering.

Definitions

Ego death and the related term "ego loss" have been defined in the context of mysticism by the religious studies scholar Daniel Merkur as "an imageless experience in which there is no sense of personal identity. It is the experience that remains possible in a state of extremely deep trance when the ego-functions of reality-testing, sense-perception, memory, reason, fantasy and self-representation are repressed [...] Muslim Sufis call it fana ('annihilation'), and medieval Jewish kabbalists termed it 'the kiss of death'".

Carter Phipps equates enlightenment and ego death, which he defines as "the renunciation, rejection and, ultimately, the death of the need to hold on to a separate, self-centered existence".

In Jungian psychology, Ventegodt and Merrick define ego death as "a fundamental transformation of the psyche". Such a shift in personality has been labeled an "ego death" in Buddhism, or a psychic death by Jung.

In comparative mythology, ego death is the second phase of Joseph Campbell's description of the Hero's Journey, which includes a phase of separation, transition, and incorporation. The second phase is a phase of self-surrender and ego-death, after which the hero returns to enrich the world with their discoveries.

In psychedelic culture, Leary, Metzner and Alpert (1964) define ego death, or ego loss as they call it, as part of the (symbolic) experience of death in which the old ego must die before one can be spiritually reborn. They define ego loss as "... complete transcendence − beyond words, beyond spacetime, beyond self. There are no visions, no sense of self, no thoughts. There are only pure awareness and ecstatic freedom".

Several psychologists working on psychedelics have defined ego-death. Alnaes (1964) defines ego death as "[L]oss of ego-feeling". Stanislav Grof (1988) defines it as "a sense of total annihilation [...] This experience of "ego death" seems to entail an instant merciless destruction of all previous reference points in the life of the individual [...] [E]go death means an irreversible end to one's philosophical identification with what Alan Watts called "skin-encapsulated ego". The psychologist John Harrison (2010) defines "[T]emporary ego death [as the] loss of the separate self[,] or, in the affirmative, [...] a deep and profound merging with the transcendent other. Johnson, Richards and Griffiths (2008), paraphrasing Leary et al. and Grof define ego death as "temporarily experienc[ing] a complete loss of subjective self-identity.

Conceptual development

The concept of "ego death" developed along a number of intertwined strands of thought, including especially the following: romantic movements and subcultures; Theosophy; anthropological research on rites de passage and shamanism; Joseph Campbell's comparative mythology; Jungian psychology; the psychedelic scene of the 1960s; and transpersonal psychology.

Western mysticism

According to Merkur,

The conceptualisation of mystical union as the soul's death, and its replacement by God's consciousness, has been a standard Roman Catholic trope since St. Teresa of Ávila; the motif traces back through Marguerite Porete, in the 13th century, to the fana, "annihilation", of the Islamic Sufis.

Jungian psychology

According to Ventegodt and Merrick, the Jungian term "psychic death" is a synonym for "ego death":

In order to radically improve global quality of life, it seems necessary to have a fundamental transformation of the psyche. Such a shift in personality has been labeled an "ego death" in Buddhism or a psychic death by Jung, because it implies a shift back to the existential position of the natural self, i.e., living the true purpose of life. The problem of healing and improving the global quality of life seems strongly connected to the unpleasantness of the ego-death experience.

Ventegodt and Merrick refer to Jung's publications The Archetypes and the Collective Unconscious, first published 1933, and Psychology and Alchemy, first published in 1944.

In Jungian psychology, a unification of archetypal opposites has to be reached, during a process of conscious suffering, in which consciousness "dies" and resurrects. Jung called this process "the transcendent function", which leads to a "more inclusive and synthetic consciousness".

Jung used analogies with alchemy to describe the individuation process, and the transference-processes which occur during therapy.

According to Leeming et al., from a religious point of view psychic death is related to St. John of the Cross' Ascent of Mt. Carmel and Dark Night of the Soul.

Mythology – The Hero with a Thousand Faces

The Hero's Journey

In 1949, Joseph Campbell published The Hero with a Thousand Faces, a study on the archetype of the Hero's Journey. It describes a common theme found in many cultures worldwide, and is also described in many contemporary theories on personal transformation. In traditional cultures it describes the "wilderness passage", the transition from adolescence into adulthood. It typically includes a phase of separation, transition, and incorporation. The second phase is a phase of self-surrender and ego-death, whereafter the hero returns to enrich the world with his discoveries. Campbell describes the basic theme as follows:

A hero ventures forth from the world of common day into a region of supernatural wonder. Fabulous forces are there encountered and a decisive victory is won. The hero comes back from this mysterious adventure with the power to bestow boons on his fellow man.

This journey is based on the archetype of death and rebirth, in which the "false self" is surrendered and the "true self" emerges. A well known example is Dante's Divine Comedy, in which the hero descends into the underworld.

Psychedelics

Concepts and ideas from mysticism and bohemianism were inherited by the Beat Generation. When Aldous Huxley helped popularize the use of psychedelics, starting with The Doors of Perception, published in 1954,  Huxley also promoted a set of analogies with eastern religions, as described in The Perennial Philosophy. This book helped inspire the 1960s belief in a revolution in western consciousness  and included the Tibetan Book of the Dead as a source. Similarly, Alan Watts, in his opening statement on mystical experiences in This Is It, draws parallels with Richard Bucke's 1901 book Cosmic Consciousness, describing the "central core" of the experience as

... the conviction, or insight, that the immediate now, whatever its nature, is the goal and fulfillment of all living.

This interest in mysticism helped shape the emerging research and popular conversation around psychedelics in the 1960s. In 1964 William S. Burroughs drew a distinction between "sedative" and "conscious-expanding" drugs. In the 1940s and 1950s the use of LSD was restricted to military and psychiatric researchers. One of those researchers was Timothy Leary, a clinical psychologist who first encountered psychedelic drugs while on vacation in 1960, and started to research the effects of psilocybin in 1961. He sought advice from Aldous Huxley, who advised him to propagate psychedelic drugs among society's elites, including artists and intellectuals. On insistence of Allen Ginsberg, Leary, together with his younger colleague Richard Alpert (Ram Dass) also made LSD available to students. In 1962 Leary was fired, and Harvard's psychedelic research program was shut down. In 1962 Leary founded the Castalia Foundation, and in 1963 he and his colleagues founded the journal The Psychedelic Review.

Following Huxley's advice, Leary wrote a manual for LSD-usage. The Psychedelic Experience, published in 1964, is a guide for LSD-trips, written by Timothy Leary, Ralph Metzner and Richard Alpert, loosely based on Walter Evans-Wentz's translation of the Tibetan Book of the Dead. Aldous Huxley introduced the Tibetan Book of the Dead to Timothy Leary. According to Leary, Metzner and Alpert, the Tibetan Book of the Dead is

... a key to the innermost recesses of the human mind, and a guide for initiates, and for those who are seeking the spiritual path of liberation.

They construed the effect of LSD as a "stripping away" of ego-defenses, finding parallels between the stages of death and rebirth in the Tibetan Book of the Dead, and the stages of psychological "death" and "rebirth" which Leary had identified during his research. According to Leary, Metzner and Alpert it is....

... one of the oldest and most universal practices for the initiate to go through the experience of death before he can be spiritually reborn. Symbolically he must die to his past, and to his old ego, before he can take his place in the new spiritual life into which he has been initiated.

Also in 1964 Randolf Alnaes published "Therapeutic applications of the change in consciousness produced by psycholytica (LSD, Psilocybin, etc.)." Alnaes notes that patients may become involved in existential problems as a consequence of the LSD experience. Psycholytic drugs may facilitate insight. With a short psychological treatment, patients may benefit from changes brought about by the effects of the experience.

One of the LSD-experiences may be the death crisis. Alnaes discerns three stages in this kind of experience:

  1. Psychosomatic symptoms lead up to the "loss of ego feeling (ego death)";
  2. A sense of separation of the observing subject from the body. The body is beheld to undergo death or an associated event;
  3. "Rebirth", the return to normal, conscious mentation, "characteristically involving a tremendous sense of relief, which is cathartic in nature and may lead to insight".

Timothy Leary's description of "ego-death"

In The Psychedelic Experience, three stages are discerned:

  1. Chikhai Bardo: ego loss, a "complete transcendence" of the self and game;
  2. Chonyid Bardo: The Period of Hallucinations;
  3. Sidpa Bardo: the return to routine game reality and the self.

Each Bardo is described in the first part of The Psychedelic Experience. In the second part, instructions are given which can be read to the "voyager". The instructions for the First Bardo state:

O (name of voyager)
The time has come for you to seek new levels of reality.
Your ego and the (name) game are about to cease.
You are about to be set face to face with the Clear Light
You are about to experience it in its reality.
In the ego−free state, wherein all things are like the void and cloudless sky,
And the naked spotless intellect is like a transparent vacuum;
At this moment, know yourself and abide in that state.
O (name of voyager),
That which is called ego−death is coming to you.
Remember:
This is now the hour of death and rebirth;
Take advantage of this temporary death to obtain the perfect state −
Enlightenment.
[...]

Scientific research

Stanislav Grof

Stanislav Grof has researched the effects of psychedelic substances, which can also be induced by nonpharmacological means. Grof has developed a "cartography of the psyche" based on his clinical work with psychedelics, which describe the "basic types of experience that become available to an average person" when using psychedelics or "various powerful non-pharmacological experiential techniques".

According to Grof, traditional psychiatry, psychology and psychotherapy use a model of the human personality that is limited to biography and the individual consciousness, as described by Freud. This model is inadequate to describe the experiences which result from the use of psychedelics and the use of "powerful techniques", which activate and mobilize "deep unconscious and superconscious levels of the human psyche". These levels include:

  • The sensory barrier and the recollective-biographical barrier
  • The perinatal matrices:
    • BPM I: The amniotic universe. Maternal womb; symbiotic unity of the fetus with the maternal organism; lack of boundaries and obstructions;
    • BPM II: Cosmic engulfment and no exit. Onset of labor; alteration of blissful connection with the mother and its pristine universe;
    • BPM III: The death-rebirth struggle. Movement through the birth channel and struggle for survival;
    • BPM IV: The death-rebirth experience. Birth and release.
  • The transpersonal dimensions of the psyche

Ego death appears in the fourth perinatal matrix. This matrix is related to the stage of delivery, the actual birth of the child. The build up of tension, pain and anxiety is suddenly released. The symbolic counterpart is the death-rebirth experience, in which the individual may have a strong feeling of impending catastrophe, and may be desperately struggling to stop this process. The transition from BPM III to BPM IV may involve a sense of total annihilation:

This experience of ego death seems to entail an instant merciless destruction of all previous reference points in the life of the individual.

According to Grof what dies in this process is "a basically paranoid attitude toward the world which reflects the negative experience of the subject during childbirth and later". When experienced in its final and most complete form,

...ego death means an irreversible end to one's philosophical identification with what Alan Watts called skin-encapsulated ego."

Recent research

Recent research also mentions that ego loss is sometimes experienced by those under the influence of psychedelic drugs.

The Ego-Dissolution Inventory is a validated self-report questionnaire that allows for the measurement of transient ego-dissolution experiences occasioned by psychedelic drugs.

View of spiritual traditions

Following the interest in psychedelics and spirituality, the term "ego death" has been used to describe the eastern notion of "enlightenment" (bodhi) or moksha.

Buddhism

Zen practice is said to lead to ego-death. Ego-death is also called "great death", in contrast to the physical "small death". According to Jin Y. Park, the ego death that Buddhism encourages makes an end to the "usually-unconsciousness-and-automated quest" to understand the sense-of-self as a thing, instead of as a process. According to Park, meditation is learning how to die by learning to "forget" the sense of self:

Enlightenment occurs when the usually automatized reflexivity of consciousness ceases, which is experienced as a letting-go and falling into the void and being wiped out of existence [...] [W]hen consciousness stops trying to catch its own tail, I become nothing, and discover that I am everything.

According to Welwood, "egolessness" is a common experience. Egolessness appears "in the gaps and spaces between thoughts, which usually go unnoticed". Existential anxiety arises when one realizes that the feeling of "I" is nothing more than a perception. According to Welwood, only egoless awareness allows us to face and accept death in all forms.

David Loy also mentions the fear of death, and the need to undergo ego-death to realize our true nature. According to Loy, our fear of egolessness may even be stronger than our fear of death.

"Egolessness" is not the same as anatta (non-self). Where the former is more of a personal experience, Anatta is a doctrine common to all of Buddhism – describing how the constituents of a person (or any other phenomena) contain no permanent entity (one has no "essence of themself"):

the Buddha, almost ad nauseam, spoke against wrong identification with the Five Aggregates, or the same, wrong identification with the psychophysical believing it is our self. These aggregates of form, feeling, thought, inclination, and sensory consciousness, he went on to say, were illusory; they belonged to Mara the Evil One; they were impermanent and painful. And for these reasons, the aggregates cannot be our self.

Taoism

The Taoist internal martial artist Bruce Frantzis reports an experience of fear of ego annihilation, or "ru ding":

I was in Hong Kong, beginning to learn the old Yang style of Tai Chi Chaun when ru ding first struck me… It was late at night, at a still and quiet terrace on the Peak, where few people came after midnight…the park was quiet, and the moon and the sky felt as though they were descending downward, putting enormous pressure on every square inch of my skin, as I tried to life my arms with the expansive energy of tai chi…I felt as if Chi from the moonlight, stars, and sky penetrated my body against my will. My body and mind became immensely still, as though they had dropped into a bottomless abyss, even though I was doing the rhythmic slow motion movements…At the depth of the stillness, an overwhelming, formless fear began to develop in my belly…. Then it happened: an all-consuming, paralyzing fear seemed all at once to invade every cell in my body… I knew if I kept practicing there would be nothing left of me in a few seconds… I stopped practicing… and ran down the hill praying hard that this terror would leave me…. The ego, goes into a mortal fear when the false reality of being separate from the universal life force is threatened by your consciousness having reached an awareness of connection to everything in existence. The ego spews forth all sorts of terrifying psychological and physiological reactions in the body and mind to make meditators petrified of leaving the state of separation.

Bernadette Roberts

Bernadette Roberts makes a distinction between "no ego" and "no self". According to Roberts, the falling away of the ego is not the same as the falling away of the self. "No ego" comes prior to the unitive state; with the falling away of the unitive state comes "no self". "Ego" is defined by Roberts as

... the immature self or consciousness prior to the falling away of its self-center and the revelation of a divine center.

Roberts defines "self" as

... the totality of consciousness, the entire human dimension of knowing, feeling and experiencing from the consciousness and unconsciousness to the unitive, transcendental or God-consciousness.

Ultimately, all experiences on which these definitions are based are wiped out or dissolved. Jeff Shore further explains that "no self" means "the permanent ceasing, the falling away once and for all, of the entire mechanism of reflective self-consciousness".

According to Roberts, both the Buddha and Christ embody the falling away of self, and the state of "no self". The falling away is represented by the Buddha prior to his enlightenment, starving himself by ascetic practices, and by the dying Jesus on the cross; the state of "no self" is represented by the enlightened Buddha with his serenity, and by the resurrected Christ.

Integration after ego-death experiences

Psychedelics

According to Nick Bromell, ego death is a tempering though frightening experience, which may lead to a reconciliation with the insight that there is no real self.

According to Grof, death crises may occur over a series of psychedelic sessions until they cease to lead to panic. A conscious effort not to panic may lead to a "pseudohallucinatory sense of transcending physical death". According to Merkur,

Repeated experience of the death crisis and its confrontation with the idea of physical death leads finally to an acceptance of personal mortality, without further illusions. The death crisis is then greeted with equanimity.

Vedanta and Zen

Both the Vedanta and the Zen-Buddhist tradition warn that insight into the emptiness of the self, or so-called "enlightenment experiences", are not sufficient; further practice is necessary.

Jacobs warns that Advaita Vedanta practice takes years of committed practice to sever the "occlusion" of the so-called "vasanas, samskaras, bodily sheaths and vrittis", and the "granthi or knot forming identification between Self and mind".

Zen Buddhist training does not end with kenshō, or insight into one's true nature. Practice is to be continued to deepen the insight and to express it in daily life. According to Hakuin, the main aim of "post-satori practice" (gogo no shugyo or kojo, "going beyond") is to cultivate the "Mind of Enlightenment". According to Yamada Koun, "if you cannot weep with a person who is crying, there is no kensho".

Dark Night and depersonalisation

Shinzen Young, an American Buddhist teacher, has pointed at the difficulty integrating the experience of no self. He calls this "the Dark Night", or

... "falling into the Pit of the Void." It entails an authentic and irreversible insight into Emptiness and No Self. What makes it problematic is that the person interprets it as a bad trip. Instead of being empowering and fulfilling, the way Buddhist literature claims it will be, it turns into the opposite. In a sense, it's Enlightenment's Evil Twin.

Willoughby Britton is conducting research on such phenomena which may occur during meditation, in a research program called "The Dark Night of the Soul". She has searched texts from various traditions to find descriptions of difficult periods on the spiritual path, and conducted interviews to find out more on the difficult sides of meditation.

Influence

The propagation of LSD-induced "mystical experiences", and the concept of ego death, had some influence in the 1960s, but Leary's brand of LSD-spirituality never "quite caught on".

Reports of psychedelic experiences

Leary's terminology influenced the understanding and description of the effects of psychedelics. Various reports by hippies of their psychedelic experiences describe states of diminished consciousness which were labelled as "ego death", but do not match Leary's descriptions. Panic attacks were occasionally also labeled as "ego death".

The Beatles

John Lennon read The Psychedelic Experience, and was strongly affected by it. He wrote "Tomorrow Never Knows" after reading the book, as a guide for his LSD trips. Lennon took about a thousand acid trips, but it only exacerbated his personal difficulties. He eventually stopped using the drug. George Harrison and Paul McCartney also concluded that LSD use didn't result in any worthwhile changes.

Radical pluralism

According to Bromell, the experience of ego death confirms a radical pluralism that most people experience in their youth, but prefer to flee from, instead believing in a stable self and a fixed reality. He further states this also led to a different attitude among youngsters in the 1960s, rejecting the lifestyle of their parents as being deceitful and false.

Controversy

The relationship between ego death and LSD has been disputed. Hunter S. Thompson, who tried LSD, saw a self-centered base in Leary's work, noting that Leary placed himself at the centre of his texts, using his persona as "an exemplary ego, not a dissolved one".  Dan Merkur notes that the use of LSD in combination with Leary's manual often did not lead to ego-death, but to horrifying bad trips.

The relationship between LSD use and enlightenment has also been criticized. Sōtō-Zen teacher Brad Warner has repeatedly criticized the idea that psychedelic experiences lead to "enlightenment experiences". In response to The Psychedelic Experience he wrote:

While I was at Starwood, I was getting mightily annoyed by all the people out there who were deluding themselves and others into believing that a cheap dose of acid, 'shrooms, peyote, "molly" or whatever was going to get them to a higher spiritual plane [...] While I was at that campsite I sat and read most of the book The Psychedelic Experience by Timothy Leary and Richard Alpert (aka Baba Ram Dass, later of Be Here Now fame). It's a book about the authors' deeply mistaken reading of the Tibetan Book of the Dead as a guide for the drug taking experience [...] It was one thing to believe in 1964 that a brave new tripped out age was about to dawn. It's quite another to still believe that now, having seen what the last 47 years have shown us about where that path leads. If you want some examples, how about Jimi Hendrix, Sid Vicious, Syd Barrett, John Entwistle, Kurt Cobain... Do I really need to get so cliched with this? Come on now.

The concept that ego-death or a similar experience might be considered a common basis for religion has been disputed by scholars in religious studies but "has lost none of its popularity". Scholars have also criticized Leary and Alpert's attempt to tie ego-death and psychedelics with Tibetan Buddhism. John Myrdhin Reynolds, has disputed Leary and Jung's use of the Evans-Wentz's translation of the Tibetan Book of the Dead, arguing that it introduces a number of misunderstandings about Dzogchen. Reynolds argues that Evans-Wentz's was not familiar with Tibetan Buddhism, and that his view of Tibetan Buddhism was "fundamentally neither Tibetan nor Buddhist, but Theosophical and Vedantist". Nonetheless, Reynolds confirms that the nonsubstantiality of the ego is the ultimate goal of the Hinayana system.

Dormancy

From Wikipedia, the free encyclopedia
During winter dormancy, plant metabolism comes to a virtual standstill, due in part to low temperatures that slow chemical activity.

Dormancy is a period in an organism's life cycle when growth, development, and (in animals) physical activity are temporarily stopped. This minimizes metabolic activity and therefore helps an organism to conserve energy. Dormancy tends to be closely associated with environmental conditions. Organisms can synchronize entry to a dormant phase with their environment through predictive or consequential means. Predictive dormancy occurs when an organism enters a dormant phase before the onset of adverse conditions. For example, photoperiod and decreasing temperature are used by many plants to predict the onset of winter. Consequential dormancy occurs when organisms enter a dormant phase after adverse conditions have arisen. This is commonly found in areas with an unpredictable climate. While very sudden changes in conditions may lead to a high mortality rate among animals relying on consequential dormancy, its use can be advantageous, as organisms remain active longer and are therefore able to make greater use of available resources.

Animals

Hibernation

Hibernation is a mechanism used by many mammals to reduce energy expenditure and survive food shortages over the winter. Hibernation may be predictive or consequential. An animal prepares for hibernation by building up a thick layer of body fat during late summer and autumn that will provide it with energy during the dormant period. During hibernation, the animal undergoes many physiological changes, including decreased heart rate (by as much as 95%) and decreased body temperature. In addition to shivering, some hibernating animals also produce body heat by non-shivering thermogenesis to avoid freezing. Non-shivering thermogenesis is a regulated process in which the proton gradient generated by electron transport in mitochondria is used to produce heat instead of ATP in brown adipose tissue. Animals that hibernate include bats, ground squirrels and other rodents, mouse lemurs, the European hedgehog and other insectivores, monotremes and marsupials. Although hibernation is almost exclusively seen in mammals, some birds, such as the common poorwill, may hibernate.

Diapause

Diapause is a predictive strategy that is predetermined by an animal's genotype. Diapause is common in insects, allowing them to suspend development between autumn and spring, and in mammals such as the roe deer (Capreolus capreolus, the only ungulate with embryonic diapause), in which a delay in attachment of the embryo to the uterine lining ensures that offspring are born in spring, when conditions are most favorable.

Aestivation

Aestivation, also spelled estivation, is an example of consequential dormancy in response to very hot or dry conditions. It is common in invertebrates such as the garden snail and worm but also occurs in other animals such as lungfish, salamanders, desert tortoises, and crocodiles.

Brumation

While endotherms and other heterotherms are described scientifically as hibernating, the way ectotherms such as lizards become dormant in cold is very different, and a separate name was invented for it in the 1920s: brumation. It differs from hibernation in the metabolic processes involved.

Reptiles generally begin brumation in late autumn (more specific times depend on the species). They often wake up to drink water and return to "sleep". They can go for months without food. Reptiles may eat more than usual before the brumation time but eat less or refuse food as the temperature drops. However, they do need to drink water. The brumation period is anywhere from one to eight months depending on the air temperature and the size, age, and health of the reptile. During the first year of life, many small reptiles do not fully brumate, but rather slow down and eat less often. Brumation is triggered by a lack of heat and a decrease in the hours of daylight in winter, similar to hibernation.

Plants

In plant physiology, dormancy is a period of arrested plant growth. It is a survival strategy exhibited by many plant species, which enables them to survive in harsh conditions and climates where part of the year is unsuitable for growth, such as winter or dry seasons.

Many plant species that exhibit dormancy have a biological clock that tells them when to slow activity and to prepare soft tissues for a period of freezing temperatures or water shortage. On the other hand, dormancy can be triggered after a normal growing season by decreasing temperatures, shortened day length, and/or a reduction in rainfall. Chemical treatment on dormant plants has been proven to be an effective method to break dormancy, particularly in woody plants such as grapes, berries, apples, peaches, and kiwis. Specifically, hydrogen cyanamide stimulates cell division and growth in dormant plants, causing buds to break when the plant is on the edge of breaking dormancy. Slight injury of cells may play a role in the mechanism of action. The injury is thought to result in increased permeability of cellular membranes. The injury is associated with the inhibition of catalase, which in turn stimulates the pentose phosphate cycle. Hydrogen cyanamide interacts with the cytokinin metabolic cycle, which results in triggering a new growth cycle. The images below show two particularly widespread dormancy patterns amongst sympodially growing orchids:

Annual life cycle of sympodially growing orchids with dormancy after completion of new growth/pseudobulb, e.g., Miltonia, or Odontoglossum
 
Annual life cycle of sympodially growing orchids with dormancy after blooming, e.g., Cycnoches ventricosum, Dendrobium nobile, or Laelia

Seeds

When a mature and viable seed under a favorable condition fails to germinate, it is said to be dormant. Seed dormancy is referred to as embryo dormancy or internal dormancy and is caused by endogenous characteristics of the embryo that prevent germination (Black M, Butler J, Hughes M. 1987). Dormancy should not be confused with seed coat dormancy, external dormancy, or hardheadedness, which is caused by the presence of a hard seed covering or seed coat that prevents water and oxygen from reaching and activating the embryo. It is a physical barrier to germination, not a true form of dormancy (Quinliven, 1971; Quinliven and Nichol, 1971).

Seed dormancy is desired in nature, but the opposite in the agriculture field. This is because agricultural practice desires rapid germination and growth for food whereas in nature, most plants are only capable of germinating once every year, making it favorable for plants to pick a specific time to reproduce. For many plants, it is preferable to reproduce in spring as opposed to fall even when there are similar conditions in terms of light and temperature due to the ensuing winter that follows fall. Many plants and seeds recognize this and enter a dormant period in the fall to stop growing. The grain is a popular example in this aspect, where they would die above ground during the winter, so dormancy is favorable to its seedlings but extensive domestication and crossbreeding has removed most dormancy mechanisms that their ancestors had.

While seed dormancy is linked to many genes, abscisic acid (ABA), a plant hormone, has been linked as a major influencer to seed dormancy. In a study on rice and tobacco plants, plants defective in zeaxanthin epoxidase gene, which are linked to ABA-synthesis pathway. Seeds with higher ABA content, from over-expressing zeaxanthin epoxidase, led to an increased dormancy period while plants with lower numbers of zeaxanthin epoxidase were shown to have a shorter period of dormancy. A simple diagram can be drawn of ABA inhibits seed germination, while gibberellin (GA, also plant hormone) inhibits ABA production and promotes seed germination.

Trees

Typically, temperate woody perennial plants require chilling temperatures to overcome winter dormancy (rest). The effect of chilling temperatures depends on species and growth stage (Fuchigami et al. 1987). In some species, rest can be broken within hours at any stage of dormancy, with either chemicals, heat, or freezing temperatures, effective dosages of which would seem to be a function of sublethal stress, which results in stimulation of ethylene production and increased cell membrane permeability.

Dormancy is a general term applicable to any instance in which a tissue predisposed to elongate or grow in some other manner does not do so (Nienstaedt 1966). Quiescence is dormancy imposed by the external environment. Correlated inhibition is a kind of physiological dormancy maintained by agents or conditions originating within the plant, but not within the dormant tissue itself. Rest (winter dormancy) is a kind of physiological dormancy maintained by agents or conditions within the organ itself. However, physiological subdivisions of dormancy do not coincide with the morphological dormancy found in white spruce (Picea glauca) and other conifers (Owens et al. 1977). Physiological dormancy often includes early stages of bud-scale initiation before measurable shoot elongation or before flushing. It may also include late leaf initiation after shoot elongation has been completed. In either of those cases, buds that appear to be dormant are nevertheless very active morphologically and physiologically.

Dormancy of various kinds is expressed in white spruce (Romberger 1963). White spruce, like many woody plants in temperate and cooler regions, requires exposure to low temperature for a period of weeks before it can resume normal growth and development. This "chilling requirement" for white spruce is satisfied by uninterrupted exposure to temperatures below 7 °C for 4 to 8 weeks, depending on physiological condition (Nienstaedt 1966, 1967).

Tree species that have well-developed dormancy needs may be tricked to some degree, but not completely. For instance, if a Japanese maple (Acer palmatum) is given an "eternal summer" through exposure to additional daylight, it grows continuously for as long as two years. Eventually, however, a temperate-climate plant automatically goes dormant, no matter what environmental conditions it experiences. Deciduous plants lose their leaves; evergreens curtail all new growth. Going through an "eternal summer" and the resultant automatic dormancy is stressful to the plant and usually fatal. The fatality rate increases to 100% if the plant does not receive the necessary period of cold temperatures required to break the dormancy. Most plants require a certain number of hours of "chilling" at temperatures between about 0 °C and 10 °C to be able to break dormancy (Bewley, Black, K.D 1994).

Short photoperiods induce dormancy and permit the formation of needle primordia. Primordia formation requires 8 to 10 weeks and must be followed by 6 weeks of chilling at 2 °C. Bud break occurs promptly if seedlings are then exposed to 16-hour photoperiods at the 25 °C/20 °C temperature regime. The free growth mode, a juvenile characteristic that is lost after 5 years or so, ceases in seedlings experiencing environmental stress (Logan and Pollard 1976, Logan 1977).

Bacteria

Many bacteria can survive adverse conditions such as temperature, desiccation, and antibiotics by forming endospores, cysts, or states of reduced metabolic activity lacking specialized cellular structures. Up to 80% of the bacteria in samples from the wild appear to be metabolically inactive—many of which can be resuscitated. Such dormancy is responsible for the high diversity levels of most natural ecosystems.

Recent research has characterized the bacterial cytoplasm as a glass forming fluid approaching the liquid-glass transition, such that large cytoplasmic components require the aid of metabolic activity to fluidize the surrounding cytoplasm, allowing them to move through a viscous, glass-like cytoplasm. During dormancy, when such metabolic activities are put on hold, the cytoplasm behaves like a solid glass, 'freezing' subcellular structures in place and perhaps protecting them, while allowing small molecules like metabolites to move freely through the cell, which may be helpful in cells transitioning out of dormancy.

Viruses

Dormancy, in its rigid definition, does not apply to viruses, as they are not metabolically active. However, some viruses such as poxviruses and picornaviruses, after entering the host, can become latent for long periods of time, or even indefinitely until they are externally activated. Herpesviruses, for example, can become latent after infecting the host, and after years they can activate again if the host is under stress or exposed to ultraviolet radiation.

Torpor

From Wikipedia, the free encyclopedia
 
Torpor is a state of decreased physiological activity in an animal, usually marked by a reduced body temperature and metabolic rate. Torpor enables animals to survive periods of reduced food availability. The term "torpor" can refer to the time a hibernator spends at low body temperature, lasting days to weeks, or it can refer to a period of low body temperature and metabolism lasting less than 24 hours, as in "daily torpor".

Animals that undergo daily torpor include birds (even tiny hummingbirds, notably Cypselomorphae) and some mammals, including many marsupial species, rodent species (such as mice), and bats. During the active part of their day, such animals maintain normal body temperature and activity levels, but their metabolic rate and body temperature drop during a portion of the day (usually night) to conserve energy.

Some animals seasonally go into long periods of inactivity, with reduced body temperature and metabolism, made up of multiple bouts of torpor. This is known as hibernation if it occurs during winter or aestivation if it occurs during the summer. Daily torpor, on the other hand, is not seasonally dependent and can be an important part of energy conservation at any time of year.

Torpor is a well-controlled thermoregulatory process and not, as previously thought, the result of switching off thermoregulation. Marsupial torpor differs from non-marsupial mammalian (eutherian) torpor in the characteristics of arousal. Eutherian arousal relies on a heat-producing brown adipose tissue as a mechanism to accelerate rewarming. The mechanism of marsupial arousal is unknown, but appears not to rely on brown adipose tissue.

Evolution

The evolution of torpor likely accompanied the development of homeothermy. Animals capable of maintaining a body temperature above ambient temperature when other members of its species would not have a fitness advantage. Benefits of maintaining internal temperatures include increased foraging time and less susceptibility to extreme drops in temperature. This adaptation of increasing body temperature to forage has been observed in small nocturnal mammals when they first wake up in the evening.

Although homeothermy lends advantages such as increased activity levels, small mammals and birds maintaining an internal body temperature spend up to 100 times more energy in low ambient temperatures compared to ectotherms. To cope with this challenge, these animals maintain a much lower body temperature, staying just over ambient temperature rather than at normal operating temperature. This reduction in body temperature and metabolic rate allows the prolonged survival of animals capable of entering torpid states.

In 2020, scientists reported evidence of the torpor in Lystrosaurus living ~250 Mya in Antarctica – the oldest evidence of a hibernation-like state in a vertebrate animal.

Functions

Slowing metabolic rate to conserve energy in times of insufficient resources is the primarily noted purpose of torpor. This conclusion is largely based on laboratory studies where torpor was observed to follow food deprivation. There is evidence for other adaptive functions of torpor where animals are observed in natural contexts:

Circadian rhythm during torpor

Animals that can enter torpor rely on biological rhythms such as circadian and circannual rhythms to continue natural functions. Different animals will manage their circadian rhythm differently, and in some species it's seen to completely stop (such as in European hamsters). Other organisms, such as a black bear, enter torpor and switch to multi-day cycles rather than rely on a circadian rhythm. However, it is seen that both captive and wild bears express similar circadian rhythms when entering torpor. Bears entering torpor in a simulated den with no light expressed normal but low functioning rhythms. The same was observed in wild bears denning in natural areas. The function of circadian rhythms in black, brown, and polar bears suggest that their system of torpor is evolutionarily advanced.

Energy conservation in small birds

Anna's hummingbird (Calypte anna) in nocturnal torpor during a cold winter night (−8 °C (18 °F) near Vancouver, British Columbia. The bird remained in torpor with an unchanged position for more than 12 hours.

Torpor has been shown to be a strategy of small migrant birds to preserve their body energy stores. Hummingbirds, resting at night during migration, were observed to enter torpor which helped to conserve fat stores during migration or cold nights at high altitude.

This strategy of using torpor to preserve energy stores, such as fat, has also been observed in wintering chickadees. Black-capped chickadees, living in temperate forests of North America, do not migrate south during winter. The chickadee can maintain a body temperature 12 °C lower than normal. This reduction in metabolism allows it to conserve 30% of fat stores amassed from the previous day.

Advantage in environments with unpredictable food sources

Torpor can be a strategy of animals with unpredictable food supplies. For example, high-latitude living rodents use torpor seasonally when not reproducing. These rodents use torpor as means to survive winter and live to reproduce in the next reproduction cycle when food sources are plentiful, separating periods of torpor from the reproduction period. The eastern long-eared bat uses torpor during winter and is able to arouse and forage during warm periods. Some animals use torpor during their reproductive cycle, as seen in unpredictable habitats. They experience the cost of a prolonged reproduction period but the payoff is survival to be able to reproduce at all.

Survival during mass extinctions

It is suggested that this daily torpor use may have allowed survival through mass extinction events. Heterotherms make up only four out of 61 mammals confirmed to have gone extinct over the last 500 years. Torpor enables animals to reduce energy requirements allowing them to better survive harsh conditions.

Inter-species competition

Interspecific competition occurs when two species require the same resource for energy production. Torpor increases fitness in the case of inter-specific competition with the nocturnal common spiny mouse. When the golden spiny mouse experiences reduced food availability by diet overlap with the common spiny mouse it spends more time in a torpid state.

Parasite resistance by bats

A drop in temperature from torpor has been shown to reduce the ability of parasites to reproduce. In temperate zones, the reproductive rates of ectoparasites on bats decrease when the bats enter torpor. In regions where bats don't undergo torpor, the parasites maintain a consistent reproductive rate throughout the year.

NASA deep sleep option for a mission to Mars

In 2013, SpaceWorks Engineering began researching a way to dramatically cut the cost of a human expedition to Mars by putting the crew in extended torpor for 90 to 180 days. Traveling while hibernating would reduce astronauts' metabolic functions and minimize requirements for life support during multi-year missions.

Grandiosity

From Wikipedia, the free encyclopedia

In psychology, grandiosity is a sense of superiority, uniqueness, or invulnerability. It may be expressed by exaggerated beliefs regarding one's abilities, the belief that few other people have anything in common with oneself, and that one can only be understood by a few, very special people. The personality trait of grandiosity is principally associated with narcissistic personality disorder (NPD), but also is a feature in the occurrence and expression of antisocial personality disorder, and the manic and hypomanic episodes of bipolar disorder.

Measurement

Few scales exist for the sole purpose of measuring grandiosity, though one recent attempt is the Narcissistic Grandiosity Scale (NGS), an adjective rating scale where one indicates the applicability of a word to oneself (e.g. superior, glorious).

Grandiosity is also measured as part of other tests, including the Personality Assessment for DSM-5 (PID-5), Psychopathy Checklist-Revised, and diagnostic interviews for NPD. The Grandiosity section of the Diagnostic Interview for Narcissism (DIN), for instance, describes:

  1. The person exaggerates talents, capacity, and achievements in an unrealistic way.
  2. The person believes in their invulnerability or does not recognize their limitations.
  3. The person has grandiose fantasies.
  4. The person believes that they do not need other people.
  5. The person overexamines and downgrades other people's projects, statements, or dreams in an unrealistic manner.
  6. The person regards themself as unique or special when compared to other people.
  7. The person regards themself as generally superior to other people.
  8. The person behaves self-centeredly and/or self-referentially.
  9. The person behaves in a boastful or pretentious way.

In narcissism

Grandiose narcissism is a subtype of narcissism with grandiosity as its central feature, in addition to other agentic and antagonistic traits (e.g., dominance, attention-seeking, entitlement, manipulation). Confusingly, the term "narcissistic grandiosity" is sometimes used as a synonym for grandiose narcissism and other times used to refer to the subject of this article (superiority feelings).

In mania

In mania, grandiosity is typically more pro-active and aggressive than in narcissism. The manic character may boast of future achievements or exaggerate their personal qualities.

They may also begin unrealistically ambitious undertakings, before being cut down, or cutting themselves back down, to size.

In psychopathy

Grandiosity features in Factor 1, Facet 1 (Interpersonal) in the Hare Psychopathy Checklist-Revised (PCL-R) test. Individuals endorsing this criterion appear arrogant and boastful, and may be unrealistically optimistic about their future. The American Psychiatric Association's DSM-5 also notes that persons with antisocial personality disorder often display an inflated self-image, and can appear excessively self-important, opinionated and cocky, and often hold others in contempt.

Relationship with other variables

Grandiosity is well documented to have associations with both positive/adaptive and negative/maladaptive outcomes, leading some researchers to question whether it is necessarily pathological.

Positive/Adaptive

Grandiosity demonstrates moderate-to-strong positive correlations with self-esteem, typically becoming larger in size when controlling for confounding variables. It relates positively to self-rated superiority and is inversely associated with self-rated worthlessness. It is also associated with a host of other variables (often even when controlling for self-esteem), including positive affect, optimism, life satisfaction, behavioural activation system functioning, and all forms of emotional resilience. It also correlates positively with adaptive narcissism, namely authoritativeness, charisma, self-assurance and ambitiousness. Moreover, it exhibits negative associations with depression, anxiety, pessimism and shame. Grandiosity has a small positive relationship with intelligence and achievement.

Negative/Maladaptive

Grandiosity has a well-studied association with aggression (both physical and verbal), risk-taking (e.g. financial, social, sexual) and competitiveness. It also has reliable associations with maladaptive narcissistic traits like entitlement and interpersonal exploitativeness. Even when controlling for exploitativeness, however, grandiosity still predicts unethical behaviours like lying, cheating and stealing. Grandiosity seems to be specifically related to rationalised cheating (i.e. opportunistic cheating behaviour whose context allows the behaviour to be construed as something other than cheating), but not deliberative cheating (i.e. conscious premeditation to violate rules and cheat).

Mechanisms

Despite the prominence of grandiosity in the research literature, few theories or even studies of its underlying mechanisms exist. Approximately 23% of the variance in grandiosity is explained by genetics, with the majority of remaining variance attributable to non-shared environmental factors.

Cognitive

Research has consistently indicated a role of positive rumination (repetitive positive self-focused thoughts). Recently, an experimental study found that having neurotypical participants engage in overly-positive rumination (i.e. think about times when they felt special, unique, important or superior) lead to increases in state grandiosity, whereas a control distraction condition conferred no such increment. Another study confirmed that positive ruminations confer grandiose self-perceptions in the moment, and found that (grandiosity-prone) patients with bipolar disorder (compared with healthy controls) exhibited heightened connectivity between brain regions associated with self-relevant information-processing during this task (medial prefrontal and anterior cingulate cortices) Further, experimental studies suggest that grandiose narcissists maintain their inflated self-esteem following criticism by recalling self-aggrandizing memories.

Correlational designs further confirm the associations of mania/hypomania and grandiose narcissism with positive self-rumination, and to specific expressions of positive rumination after success (e.g. believing that success in one domain indicates likely success in another). Grandiose fantasies, conceptually similar to positive rumination, also feature in narcissism. While grandiose narcissism has been associated with attentional and mnemonic biases to positive self-related words, it remains to be seen whether this reflects grandiosity or some other trait specific to narcissism (e.g. entitlement).

Other theories

A common characteristic of disorders and traits associated with grandiosity is heightened positive affect and potential dysregulation thereof. This is true of mania/hypomania in bipolar disorder, grandiose narcissism, and the interpersonal facet of psychopathy. Such associations partially inspired the Narcissism Spectrum Model, which posits grandiosity reflects the combination of self-preoccupation and "boldness" - exaggerated positive emotionality, self-confidence, and reward-seeking, which is ostensibly linked with neurobiological systems mediating behavioural approach motivation.

While no neuroimaging studies have specifically assessed the association between grandiosity and the reward system (or any other system), some neuroimaging studies using composite scales of grandiosity with other traits offer tentative support of these assertions, while others using the same measure suggest no association.

Contrary to frequent assertions by narcissism researchers, and despite much study of the matter, there is only weak and inconsistent evidence that grandiosity (when specifically and reliably measured) and grandiose narcissism have any association with parental overvaluation. The largest study on the matter found no association whatsoever.

Reality-testing

A distinction is made between individuals exhibiting grandiosity which includes a degree of insight into their unrealistic thoughts (they are aware that their behavior is considered unusual), and those experiencing grandiose delusions who lack this capability for reality-testing. Some individuals may transition between these two states, with grandiose ideas initially developing as "daydreams" that the patient recognises as untrue, but which can subsequently turn into full delusions that the patient becomes convinced reflect reality.

Psychoanalysis and the grandiose self

Otto Kernberg saw the unhealthily grandiose self as merging childhood feelings of specialness, personal ideals, and fantasies of an ideal parent.

Heinz Kohut saw the grandiose self as a normal part of the developmental process, only pathological when the grand and humble parts of the self became decisively divided. Kohut's recommendations for dealing with the patient with a disordered grandiose self were to tolerate and so re-integrate the grandiosity with the realistic self.

Reactive attachment disorder

The personality trait of grandiosity also is a component of the reactive attachment disorder (RAD), a severe and relatively uncommon attachment disorder that affects children. The expression of RAD is characterized by markedly disturbed and developmentally inappropriate ways of relating to other people in most social contexts, such as the persistent failure to initiate or to respond to most social interactions in a developmentally appropriate way, known as the "inhibited form" of reactive attachment disorder.

Related traits

Grandiosity is associated and often confused with other personality traits, including self-esteem, entitlement, and contemptuousness.

Self-esteem
While the exact difference between high self-esteem and grandiosity has yet to be fully elucidated, research suggests that, while strongly correlated, they predict different outcomes. While both predict positive outcomes like optimism, life and job satisfaction, extraversion and positive affect, grandiosity uniquely predicts entitlement, exploitativeness and aggression.
Entitlement
Entitlement is regularly confused with grandiosity even in peer-reviewed articles, but the literature nevertheless offers a clear discrimination of the two. Psychological entitlement is a sense of deservingness to positive outcomes, and can be founded on either grandiosity or feelings of deprivation. Like self-esteem, grandiosity and entitlement are well documented to predict different outcomes. Entitlement appears to be associated with more maladaptive outcomes, including low empathy, antisocial behaviour, and poor mental health, whereas grandiosity predicts better mental health.
Devaluation/contempt
Surprisingly, and quite counterintuitively, grandiosity is only weakly related to regarding others as worthless (devaluation or contemptuousness). Moreover, grandiosity should not be conflated with arrogant social behaviour.

Grandiose delusions

Grandiose delusions
Other namesExpansive delusions

SpecialtyPsychiatry

Grandiose delusions (GD), also known as delusions of grandeur or expansive delusions, are a subtype of delusion that occur in patients with a wide range of psychiatric disorders, including two-thirds of patients in a manic state of bipolar disorder, half of those with schizophrenia, patients with the grandiose subtype of delusional disorder, frequently as a comorbid condition in narcissistic personality disorder, and a substantial portion of those with substance abuse disorders. GDs are characterized by fantastical beliefs that one is famous, omnipotent, wealthy, or otherwise very powerful. The delusions are generally fantastic and typically have a religious, science fictional, or supernatural theme. There is a relative lack of research into GD, in contrast to persecutory delusions and auditory hallucinations. Around 10% of healthy people experience grandiose thoughts at some point in their lives but do not meet full criteria for a diagnosis of GD.

While similarly named and sharing some features in common, grandiose delusions are distinct from grandiosity. While GDs refer to beliefs about nonexistent fame, wealth, powers, or religious and historical relevance, grandiosity refers to feelings of superiority, uniqueness, importance or invulnerability, and is best understood as a form of self-regard.

Signs and symptoms

According to the DSM-IV-TR diagnostic criteria for delusional disorders, grandiose-type symptoms include exaggerated beliefs of:

  • self-worth
  • power
  • knowledge
  • identity
  • exceptional relationship to a deity or famous person.

For example, a patient who has fictitious beliefs about their power or authority may believe themselves to be a ruling monarch who deserves to be treated like royalty. There are substantial differences in the degree of grandiosity linked with grandiose delusions in different patients. Some patients believe they are God, the Queen of the United Kingdom, a president's son, a famous rock star, and some other examples. Others are not as expansive and think they are skilled athletes or great inventors.

Expansive delusions may be maintained by auditory hallucinations, which advise the patient that they are significant, or confabulations, when, for example, the patient gives a thorough description of their coronation or marriage to the king. Grandiose and expansive delusions may also be part of fantastic hallucinosis in which all forms of hallucinations occur.

Positive functions

Grandiose delusions frequently serve a very positive function by sustaining or increasing the patient's self-esteem. As a result, it is essential to consider the consequences of removing the grandiose delusion on self-esteem when trying to modify the grandiose delusion in therapy. In many instances of grandiosity, it is suitable to go for a fractional rather than a total modification, which permits those elements of the delusion that are central for self-esteem to be preserved. For example, a person who believes they are a senior secret service agent gains a great sense of self-esteem and purpose from this belief, thus until this sense of self-esteem can be provided from elsewhere, it is best not to attempt modification.

In a case study of more than 13,000 non-clinical and almost 3000 clinical participants, Isham et al. found that the primary sources of meaning derived from grandiose delusions were:

  • Confidence in the self
  • Overcoming adversity
  • The "greater good"
  • Happiness
  • Supporting loved ones
  • Positive social perception
  • Spirituality

Comorbidity

Schizophrenia

Schizophrenia is a mental disorder distinguished by a loss of contact with reality and the occurrence of psychotic behaviors, including hallucinations and delusions (unreal beliefs which endure even when there is contrary evidence). Delusions may include the false and constant idea that the person is being followed or poisoned, or that the person’s thoughts are being broadcast for others to listen to. Delusions in schizophrenia often develop as a response to the individual attempting to explain their hallucinations. Patients who experience recurrent auditory hallucinations can develop the delusion that other people are scheming against them and are dishonest when they say they do not hear the voices that the delusional person believes that he or she hears.

Specifically, grandiose delusions are frequently found in paranoid schizophrenia, in which a person has an extremely exaggerated sense of their significance, personality, knowledge, or authority. For example, the person may declare to own a major corporation and kindly offer to write a hospital staff member a check for $5 million if only help them escape from the hospital. Other common grandiose delusions in schizophrenia include religious delusions such as the belief that one is Jesus Christ, or the Mahdi of End time in Muslim societies.

Bipolar disorder

Bipolar 1 disorder can lead to severe affective dysregulation, or mood states that sway from exceedingly low (depression) to exceptionally high (mania). In hypomania or mania, some bipolar patients can have grandiose delusions. In its most severe manifestation, days without sleep, auditory and other hallucinations, or uncontrollable racing thoughts can reinforce these delusions. In mania, this illness affects emotions and can also lead to impulsivity and disorganized thinking, which can be harnessed to increase their sense of grandiosity. Protecting this delusion can also lead to extreme irritability, paranoia, and fear. Sometimes their anxiety can be so over-blown that they believe others are jealous of them and, thus, undermine their "extraordinary abilities," persecuting them or even scheming to seize what they already have.

The vast majority of bipolar patients rarely experience delusions. Typically, when experiencing or displaying a stage of heightened excitability called mania, they can experience joy, rage, and other intense emotions that can cycle out of control, along with thoughts or beliefs that are grandiose. Some of these grandiose thoughts can be expressed as strong beliefs that the patient is very rich or famous or has super-human abilities, or can even lead to severe suicidal ideations. In the most severe form, in what was formerly labeled as megalomania, the bipolar patient may hear voices that support these grandiose beliefs. In their delusions, they can believe that they are, for example, a king, a creative genius, or can even exterminate the world's poverty because of their extreme generosity.

Theories and mechanisms

Psychologists and psychiatrists have proposed multiple theoretical accounts of GDs:

  • Delusion-as-defense: defense of the mind against lower self-esteem and depression.
  • Emotion-consistent: result of exaggerated positive emotions.

Empirical evidence largely supports emotion-consistent models, but also suggests additional factors like reasoning biases. Grandiose delusions are usually associated with high self-esteem and self-serving attributional style and low levels of depression, anxiety and negative self-evaluation. Moreover, there is evidence from neurotypical persons that repetitive positive self-thinking can confer temporary increases in (non-delusional) grandiose ideas of own superiority, importance or uniqueness. A functional magnetic resonance imaging (fMRI) study of patients with bipolar disorder found that such thinking is associated with exaggerated connectivity between the medial prefrontal cortex and anterior cingulate cortex (brain regions involved in self-relevant information-processing).

Qualitative research likewise indicates that grandiose delusions, far from occurring against a backdrop of negative self-evaluation, conferred a sense of uniqueness, purpose, and belonging, and added meaning to adverse events.

The defensive hypothesis bears a strong similarity to the psychodynamic mask model of non-delusional narcissistic grandiosity, which is also unsupported by the evidence.

Neurobiology

Grandiose delusions may be related to lesions of the frontal lobe. Temporal lobe lesions have been mainly reported in patients with delusions of persecution and of guilt, while frontal and frontotemporal involvement have been described in patients with grandiose delusions, Cotard’s syndrome, and delusional misidentification syndrome.

Some studies indicate that GDs are associated with abnormalities in dopaminergic reward pathways and other limbic structures associated with reward and emotion processing. GDs seem to be related to impaired connectivity between the left middle temporal gyrus and more dorsal regions of the left temporal lobe, regions forming a central hub of the default mode network and mediating a variety of cognitive functions (namely social and linguistic ones).

Diagnosis

Patients with a wide range of mental disorders which disturb brain function experience different kinds of delusions, including grandiose delusions. Grandiose delusions usually occur in patients with syndromes associated with secondary mania, such as Huntington's disease, Parkinson's disease, and Wilson's disease. Secondary mania has also been caused by substances such as L-DOPA and isoniazid which modify the monoaminergic neurotransmitter function. Vitamin B12 deficiency, uremia, hyperthyroidism as well as the carcinoid syndrome have been found to cause secondary mania, and thus grandiose delusions.

In diagnosing delusions, the MacArthur-Maudsley Assessment of Delusions Schedule is used to assess the patient.

Treatment

In patients with schizophrenia, grandiose and religious delusions are found to be the least susceptible to cognitive behavioral interventions. Cognitive behavioral intervention is a form of psychological therapy, initially used for depression, but currently used for a variety of different mental disorders, in hope of providing relief from distress and disability. During therapy, grandiose delusions were linked to patients' underlying beliefs by using inference chaining. Some examples of interventions performed to improve the patient's state were focus on specific themes, clarification of patient's neologisms, and thought linkage. During thought linkage, the patient is asked repeatedly by the therapist to explain his/her jumps in thought from one subject to a completely different one.

Patients with mental disorders that experience grandiose delusions have been found to have a lower risk of having suicidal thoughts and attempts.

Epidemiology

In researching over 1000 individuals of a vast range of backgrounds, Stompe and colleagues (2006) found that grandiosity remains as the second most common delusion after persecutory delusions. A variation in the occurrence of grandiosity delusions in schizophrenic patients across cultures has also been observed. In research done by Appelbaum et al. it has been found that GDs appeared more commonly in patients with bipolar disorder (59%) than in patients with schizophrenia (49%), followed by presence in substance misuse disorder patients (30%) and depressed patients (21%).

A relationship has been claimed between the age of onset of bipolar disorder and the occurrence of GDs. According to Carlson et al. (2000), grandiose delusions appeared in 74% of the patients who were 21 or younger at the time of the onset, while they occurred only in 40% of individuals 30 years or older at the time of the onset.

Prevalence

Research suggests that the severity of the delusions of grandeur is directly related to a higher self-esteem in individuals and inversely related to any individual’s severity of depression and negative self-evaluations. Lucas et al. found that there is no significant gender difference in the establishment of grandiose delusion. However, there is a claim that ‘the particular content of Grandiose delusions’ may be variable across both genders. Also, it has been noted that the presence of GDs in people with at least grammar or high school education was greater than lesser educated persons. Similarly, the presence of grandiose delusions in individuals who are the eldest is greater than in individuals who are the youngest of their siblings.

Impostor syndrome

From Wikipedia, the free encyclopedia

Impostor syndrome, also known as impostor phenomenon or impostorism, is a psychological occurrence in which people doubt their skills, talents, or accomplishments and have a persistent internalized fear of being exposed as frauds. Despite external evidence of their competence, those experiencing this phenomenon do not believe they deserve their success or luck. They may incorrectly attribute it to the Matthew effect or the Dunning–Kruger effect, or they may think that they are deceiving others because they feel as if they are not as intelligent as they outwardly portray themselves to be. Impostor syndrome can stem from and result in strained personal relationships and can hinder individuals from achieving their full potential in their fields of interest.

When impostor syndrome was first conceptualized, it was viewed as a phenomenon that was common among high-achieving women. Further research has shown that it affects both men and women, in the collective sense that the proportion affected are more or less equally distributed among the genders. Individuals with impostor syndrome often have corresponding mental health issues, which may be treated with psychological interventions, though the phenomenon is not a formal mental disorder.

History

The term impostor phenomenon was introduced in an article published in 1978, titled "The Impostor Phenomenon in High Achieving Women: Dynamics and Therapeutic Intervention" by Pauline R. Clance and Suzanne A. Imes. Clance and Imes defined impostor phenomenon as "an internal experience of intellectual phoniness" and initially focused their research on women in higher education and professional industries.

The researchers surveyed over 100 women, approximately one-third of whom were involved in psychotherapy for reasons besides impostor syndrome and two-thirds of whom they knew from their own lectures and therapy groups. All of the participants had been formally recognized for their professional excellence by colleagues and displayed academic achievement through educational degrees and standardized testing scores. Despite the consistent external validation these women received, they lacked internal acknowledgement of their accomplishments. When asked about their success, some participants attributed it to luck, while some believed that people had overestimated their capabilities. Clance and Imes believed that this mental framework of impostor phenomenon developed from factors such as gender stereotypes, familial problems, cultural norms, and attribution style. They discovered that the women in the study experienced symptoms of "generalized anxiety, lack of self-confidence, depression, and frustration related to inability to meet self-imposed standards of achievement."

Psychopathology

Certain individuals with impostor syndrome may see themselves as less ill (less depressed, less anxious) than their peers or other mentally ill people, citing their lack of severe symptoms as the indication of the absence of or a minor underlying issue. People with this mindset often do not seek help for their issues because they see their problems as not worthy of psychiatric attention.

Impostor phenomenon is studied as a reaction to particular stimuli and events. It is an experience that occurs in an individual, not a mental disorder. Impostor phenomenon is not recognized in the DSM or ICD, although both of these classification systems recognize low self-esteem and sense of failure as associated symptoms of depression.

Measuring impostor phenomenon

The first scale designated to measure characteristics of impostor phenomenon was designed by Clance in 1985, called the Clance Impostor Phenomenon Scale (CIPS). The scale can be used to determine if characteristics of fear are present in the individual, and to what extent. The aspects of fear include: "fear of evaluation, fear of not continuing success and fear of not being as capable as others." Characteristics of impostor syndrome such as an individual's self-esteem and their perspective of how they achieve success are measured by the CIPS. A sample of 1271 engineering college students were studied by Brian F. French, Sarah C. Ullrich-French, and Deborah Follman to examine the psychometric properties of the CIPS. They found that scores of the scales' individual components were not entirely reliable or consistent and suggested that these should not be used to make significant decisions about individuals with the syndrome.

In her 1985 paper, Clance explained that impostor phenomenon can be distinguished by the following six characteristics, of which an individual who has impostorism must experience at least two: 

  1. The impostor cycle
  2. The need to be special or the best
  3. Characteristics of superman/superwoman
  4. Fear of failure
  5. Denial of ability and discounting praise
  6. Feeling fear and guilt about success

Occurrence

It has been estimated that nearly 70% of individuals will experience signs and symptoms of impostor phenomenon at least once in their life. Research shows that impostor phenomenon is not uncommon for students who enter a new academic environment. Feelings of insecurity can come as a result of an unknown, new environment. This can lead to lower self-confidence and belief in their own abilities.

Gender differences

Clance and Imes stated in their 1978 article that, based on their clinical experience, impostor phenomenon was less prevalent in men. However, more recent research has mostly found that impostor phenomenon is spread equally among men and women. Research has shown that women commonly face impostor phenomenon in regard to performance. The perception of ability and power is evidenced in out-performing others. For men, impostor phenomenon is often driven by the fear of being unsuccessful, or not good enough.

Settings

Impostor phenomenon can occur in other various settings. Some examples include a new environment, academic settings, in the workplace, social interactions, and relationships (platonic or romantic).

In relationships, people with impostorism often feel they do not live up to the expectations of their friends or loved ones. It is common for the individual with impostorism to think that they must have somehow tricked others into liking them and wanting to spend time with them. They experience feelings of being unworthy, or of not deserving the beneficial relationships they possess.

There is empirical evidence that demonstrates the harmful effects of impostor phenomenon in students. Studies have shown that when a student's academic self-concept increases, the symptoms of impostor phenomenon decrease, and vice versa. The worry and emotions the students held, had a direct impact of their performance in the program. Common facets of impostor phenomenon experienced by students include not feeling prepared academically (especially when comparing themselves to classmates), questioning the grounds on which they were accepted into the program, and perceiving that positive recognition, awards, and good grades stemmed from external factors rather than personal ability or intelligence.

Cokley et al. investigated the impact impostor phenomenon has on students, specifically ethnic minority students. They found that the feelings the students had of being fraudulent resulted in psychological distress. Ethnic minority students often questioned the grounds on which they were accepted into the program. They held the false assumption that they only received their acceptance due to affirmative action—rather than an extraordinary application and qualities they had to offer.

Tigranyan et al. (2021) examined the way impostor phenomenon relates to psychology doctoral students. The purpose of the study was to investigate the IP's relationship to perfectionistic cognitions, depression, anxiety, achievement motives, self-efficacy, self-compassion, and self-esteem in clinical and counseling psychology doctoral students. Furthermore, this study sought to investigate how IP interferes with academic, practicum, and internship performance of these students and how IP manifests throughout a psychology doctoral program. Included were 84 clinical and counseling psychology doctoral students and they were instructed to respond to an online survey. The data was analyzed using a Pearson's product-moment correlation and a multiple linear regression. Eighty-eight percent of the students in the study reported at least moderate feelings of IP characteristics. This study also found significant positive correlations between the IP and perfectionistic cognitions, depression, anxiety, and self-compassion. This study indicates that clinical faculty and supervisors should take a supportive approach to assist students to help decrease feelings of IP, in hopes of increasing feelings of competence and confidence.

Connections

Research has shown that there is a relationship between impostor phenomenon and the following factors:

  • Family expectations
  • Overprotective parent(s) or legal guardian(s)
  • Graduate-level coursework
  • Racial identities
  • Attribution style
  • Anxiety
  • Depression
  • Low trait self-esteem
  • Perfectionism
  • Excessive self-monitoring, with an emphasis on self-worth

The aspects listed are not mutually exclusive. These components are often found to correlate among individuals with impostor phenomenon. It is incorrect to infer that the correlational relationship between these aspects cause the impostor experience.

In individuals with impostor phenomenon, feelings of guilt often result in a fear of success. The following are examples of common notions that lead to feelings of guilt and reinforce the phenomenon.

  • The good education they were able to receive
  • Being acknowledged by others for success
  • Belief that it is not right or fair to be in a better situation than a friend or loved one
  • Being referred to as:
    • "The smart one"
    • "The talented one"
    • "The responsible one"
    • "The sensitive one"
    • "The good one"
    • "Our favorite"

Management

In their 1978 paper, Clance and Imes proposed a therapeutic approach they used for their participants or clients with impostor phenomenon. This technique includes a group setting where various individuals meet others who are also living with this experience. The researchers explained that group meetings made a significant impact on their participants. They proposed that this impact was a result of the realization that they were not the only ones who experienced these feelings. The participants were required to complete various homework assignments as well. In one assignment, participants recalled all of the people they believed they had fooled or tricked in the past. In another take-home task, individuals wrote down the positive feedback they had received. Later, they would have to recall why they received this feedback and what about it made them perceive it in a negative light. In the group sessions, the researchers also had the participants re-frame common thoughts and ideas about performance. An example would be to change: "I might fail this exam" to "I will do well on this exam".

The researchers concluded that simply extracting the self-doubt before an event occurs helps eliminate feelings of impostorism. It was recommended that the individuals struggling with this experience seek support from friends and family. Although impostor phenomenon is not a pathological condition, it is a distorted system of belief about oneself that can have a powerful negative impact on an individual's valuation of their own worth. Impostor syndrome is not a recognized psychiatric disorder: It is not featured in the American Psychiatric Association's Diagnostic and Statistical Manual nor is it listed as a diagnosis in the International Classification of Diseases, Tenth Revision (ICD-10). Outside the academic literature, impostor syndrome has become widely discussed, especially in the context of achievement in the workplace. Perhaps because it is not an officially recognized clinical diagnosis, despite the large peer review and lay literature, although there has been a qualitative review, there has never been a published systematic review of the literature on impostor syndrome. Thus, clinicians lack evidence on the prevalence, comorbidities, and best practices for diagnosing and treating impostor syndrome.

Other research on therapeutic approaches for impostorism emphasizes the importance of self-worth. Individuals who live with impostor phenomenon commonly relate self-esteem and self-worth to others. A major aspect of other therapeutic approaches for impostor phenomenon focus on separating the two into completely separate entities.

In a study in 2013, researcher Queena Hoang proposed that intrinsic motivation can decrease the feelings of being a fraud that are common in impostor phenomenon. Hoang also suggested that implementing a mentor program for new or entering students will minimize students' feelings of self-doubt. Having a mentor who has been in the program will help the new students feel supported. This allows for a much smoother and less overwhelming transition.

Impostor experience can be addressed with many kinds of psychotherapy. Group psychotherapy is an especially common and effective way of alleviating the impostor experience.
