Asociality

Last updated

Asociality refers to the lack of motivation to engage in social interaction, or a preference for solitary activities. Asociality may be associated with avolition, but it can, moreover, be a manifestation of limited opportunities for social relationships. [1] Developmental psychologists use the synonyms nonsocial, unsocial, and social uninterest. Asociality is distinct from, but not mutually exclusive to, anti-social behavior. A degree of asociality is routinely observed in introverts, while extreme asociality is observed in people with a variety of clinical conditions.

Contents

Asociality is not necessarily perceived as a totally negative trait by society, since asociality has been used as a way to express dissent from prevailing ideas. It is seen as a desirable trait in several mystical and monastic traditions, notably in Hinduism, Jainism, Roman Catholicism, Eastern Orthodoxy, Buddhism [2] [3] [4] [5] [6] and Sufism. [7]

Introversion

Introversion is "the state of or tendency toward being wholly or predominantly concerned with and interested in one's own mental life." [8] Introverted persons are considered the opposite of extraverts, who seem to thrive in social settings rather than being alone. An introvert may present as an individual preferring being alone or interacting with smaller groups over interaction with larger groups, writing over speaking, having fewer but more fulfilling friendships, and needing time for reflection. [9] While not a measurable personality trait, some popular writers have characterized introverts as people whose energy tends to expand through reflection and dwindle during interaction. [10]

In matters of the brain, researchers have found differences in anatomy between introverted and extraverted persons. [9] Introverted people are found to experience a higher flow of blood to the frontal lobe than extraverts, which is the part of the brain that contributes to problem-solving, memory, and preemptive thought. [9]

Social anhedonia

Social anhedonia is found in both typical and extreme cases of asociality or personality disorders that feature social withdrawal. Social anhedonia is distinct from introversion and is frequently accompanied with alexithymia. [11]

Many cases of social anhedonia are marked by extreme social withdrawal and the complete avoidance of social interaction. [12] One research article studying the individual differences in social anhedonia [13] [14] discusses the negative aspects of this form of extreme or aberrant asociality. Some individuals with social anhedonia are at higher risk of developing schizophrenia and may have mental functioning that becomes poorer than the average. [13]

In human evolution and anthropology

Scientific research suggests that asocial traits in human behavior, personality, and cognition may have several useful evolutionary benefits. Traits of introversion and aloofness can protect an individual from impulsive and dangerous social situations because of reduced impulsivity and reward. [15] Frequent voluntary seclusion stimulates creativity and can give the individual time to think, work, reflect, and see useful patterns more easily. [16]

Research indicates the social and analytical functions of the brain function in a mutually exclusive way. [17] With this in mind, researchers posit that people who devoted less time or interest to socialization used the analytical part of the brain more frequently and thereby were often responsible for devising hunting strategies, creating tools, and spotting useful patterns in the environment in general for both their own safety and the safety of the group. [18] [19] [20]

Imitation and social learning have been confirmed to be potentially limiting and maladaptive in animal and human populations. [21] When social learning overrides personal experience (asocial learning), negative effects can be observed such as the inability to seek or pick the most efficient way to accomplish a task [22] and a resulting inflexibility to changing environments. [23] [24] Individuals who are less receptible, motivated, and interested in sociability are likely less affected by or sensible to socially imitated information [25] and faster to notice and react to changes in the environment, [26] [27] essentially holding onto their own observations in a rigid manner and, consequently, not imitating a maladaptive behavior through social learning. These behaviors, including deficits in imitative behavior, have been observed in individuals with autism spectrum disorders [20] [28] [29] and introverts, [30] and are correlated with the personality traits of neuroticism and disagreeableness. [25]

The benefits of this behavior for the individual and their kin caused it to be preserved in part of the human population. The usefulness for acute senses, [31] novel discoveries, and critical analytical thought [32] may have culminated in the preservation of the suspected genetic factors of autism and introversion itself due to their increased cognitive, sensorial, and analytical awareness. [33] [34]

In psychopathology

Schizophrenia

In schizophrenia, asociality is one of the main five "negative symptoms", with the others being avolition, anhedonia, reduced affect, and alogia. Due to a lack of desire to form relationships, social withdrawal is common in people with schizophrenia. [35] [36] [37] People with schizophrenia may experience social deficits or dysfunction as a result of the disorder, leading to asocial behavior. Frequent or ongoing delusions and hallucinations can deteriorate relationships and other social ties, isolating individuals with schizophrenia from reality and in some cases leading to homelessness. Even when treated with medication for the disorder, they may be unable to engage in social behaviors. These behaviors include things like maintaining conversations, accurately perceiving emotions in others, or functioning in crowded settings. There has been extensive research on the effective use of social skills training (SST) for the treatment of schizophrenia, in outpatient clinics as well as inpatient units. SST can be used to help patients with schizophrenia make better eye contact with other people, increase assertiveness, and improve their general conversational skills. [38]

Personality disorders

Avoidant personality disorder

Asociality is common amongst people with avoidant personality disorder (AvPD). They experience discomfort and feel inhibited in social situations, being overwhelmed by feelings of inadequacy. Such people remain consistently fearful of social rejection, choosing to avoid social engagements as they do not want to give people the opportunity to reject (or possibly, accept) them. Though they inherently crave a sense of belonging, their fear of criticism and rejection leads people with AvPD to actively avoid occasions that require social interaction, leading to extremely asocial tendencies; as a result, these individuals often have difficulty cultivating and preserving close relationships. [39]

People with AvPD may also display social phobia, the difference being that social phobia is the fear of social circumstances whereas AvPD is better described as an aversion to intimacy in relationships. [40]

Schizoid personality disorder

Schizoid personality disorder (SzPD) is characterized by a lack of interest in social relationships, a tendency towards a solitary lifestyle, secretiveness, emotional coldness, and apathy. Affected individuals may simultaneously demonstrate a rich and elaborate but exclusively internal fantasy world. [41]

It is not the same as schizophrenia, although they share such similar characteristics as detachment and blunted affect. There is, moreover, increased prevalence of the disorder in families with schizophrenia. [42]

Schizotypal personality disorder

Schizotypal personality disorder is characterized by a need for social isolation, anxiety in social situations, odd behavior and thinking, and often unconventional beliefs. People with this disorder feel extreme discomfort with maintaining close relationships with people, and therefore they often do not. People who have this disorder may display peculiar manners of talking and dressing and often have difficulty in forming relationships. In some cases, they may react oddly in conversations, not respond, or talk to themselves. [43]

Autism

Autistic people may display profoundly asocial tendencies, due to differences in how autistic and allistic (non-autistic) people communicate. These different communication styles can cause mutual friction between the two neurotypes, [44] known as the double empathy problem. Autistic people tend to express emotions differently and less intensely than allistic people, and often do not pick up on allistic social cues or linguistic pragmatics (including eye contact, facial expressions, tone of voice, body language, and implicatures) used to convey emotions and hints.

Connecting with others is important to overall health. An increased difficulty in accurately reading social cues by others can affect this desire for people with autism. The risk of adverse social experiences is high for those with autism, and so they may prefer to be avoidant in social situations rather than experience anxiety over social performance. Social deficits in people with autism is directly correlated with the increased prevalence of social anxiety in this community. [45] As they are in a steep minority, there is risk of not having access to like-minded peers in their community, which can lead them to withdrawal and social isolation.

Mood disorders

Depression

Asociality can be observed in individuals with major depressive disorder or dysthymia, as individuals lose interest in everyday activities and hobbies they used to enjoy, this may include social activities, resulting in social withdrawal and withdrawal tendencies. [46]

SST can be adapted to the treatment of depression with a focus on assertiveness training. Depressed patients often benefit from learning to set limits with others, to obtain satisfaction for their own needs, and to feel more self-confident in social interactions. Research suggests that patients who are depressed because they tend to withdraw from others can benefit from SST by learning to increase positive social interactions with others instead of withdrawing from social interactions. [47]

Social anxiety disorder

Asocial behavior is observed in people with social anxiety disorder (SAD), who experience perpetual and irrational fears of humiliating themselves in social situations. They often have panic attacks and severe anxiety as a result, which can occasionally lead to agoraphobia. The disorder is common in children and young adults, diagnosed on average between the ages of 8 and 15. [48] If left untreated, people with SAD exhibit asocial behavior into adulthood, avoiding social interactions and career choices that require interpersonal skills. SST can help people with social phobia or shyness to improve their communication and social skills so that they will be able to mingle with others or go to job interviews with greater ease and self-confidence. [49]

Traumatic brain injury

Traumatic brain injuries (TBI) can also lead to asociality and social withdrawal. [50]

Management

Treatments

Social skills training

Social skills training (SST) is an effective technique aimed towards anyone with "difficulty relating to others," a common symptom of shyness, marital and family conflicts, or developmental disabilities; as well as of many mental and neurological disorders including adjustment disorders, anxiety disorders, attention-deficit/hyperactivity disorder, social phobia, alcohol dependence, depression, bipolar disorder, schizophrenia, avoidant personality disorder, paranoid personality disorder, obsessive-compulsive disorder, and schizotypal personality disorder.

Fortunately for people who display difficulty relating to others, social skills can be learned, as they are not simply inherent to an individual's personality or disposition. Therefore, there is hope for anyone who wishes to improve their social skills, including those with psychosocial or neurological disorders. Nonetheless, it is important to note that asociality may still be considered neither a character flaw nor an inherently negative trait.

SST includes improving eye contact, speech duration, frequency of requests, and the use of gestures, as well as decreasing automatic compliance to the requests of others. SST has been shown to improve levels of assertiveness (positive and negative) in both men and women.

Additionally, SST can focus on receiving skills (e.g. accurately perceiving problem situations), processing skills (e.g. considering several response alternatives), and sending skills (delivering appropriate verbal and non-verbal responses). [51]

Metacognitive interpersonal therapy

Metacognitive interpersonal therapy is a method of treating and improving the social skills of people with personality disorders that are associated with asociality. Through metacognitive interpersonal therapy, clinicians seek to improve their patients' metacognition, meaning the ability to recognize and read the mental states of themselves. The therapy differs from SST in that the patient is trained to identify their own thoughts and feelings as a means of recognizing similar emotions in others. Metacognitive interpersonal therapy has been shown to improve interpersonal and decision-making skills by encouraging awareness of suppressed inner states, which enables patients to better relate to other people in social environments.

The therapy is often used to treat patients with two or more co-occurring personality disorders, commonly including obsessive-compulsive and avoidant behaviors. [52]

Coping mechanisms

In order to cope with asocial behavior, many individuals, especially those with avoidant personality disorder, develop an inner world of fantasy and imagination to entertain themselves when feeling rejected by peers. Asocial people may frequently imagine themselves in situations where they are accepted by others or have succeeded at an activity. Additionally, they may have fantasies relating to memories of early childhood and close family members. [53]

Shyness is the feeling of apprehension, lack of comfort, or awkwardness especially when a person is around other people. This commonly occurs in new situations or with unfamiliar people; a shy person may simply opt to avoid these situations. Although shyness can be a characteristic of people who have low self-esteem, the primary defining characteristic of shyness is a fear of what other people will think of a person's behavior. This fear of negative reactions such as being mocked, humiliated or patronized, criticized or rejected can cause a shy person to retreat. Stronger forms of shyness can be referred to as social anxiety or social phobia.

Psychology is an academic and applied discipline involving the scientific study of human mental functions and behavior. Occasionally, in addition or opposition to employing the scientific method, it also relies on symbolic interpretation and critical analysis, although these traditions have tended to be less pronounced than in other social sciences, such as sociology. Psychologists study phenomena such as perception, cognition, emotion, personality, behavior, and interpersonal relationships. Some, especially depth psychologists, also study the unconscious mind.

Schizoid personality disorder is a personality disorder characterized by a lack of interest in social relationships, a tendency toward a solitary or sheltered lifestyle, secretiveness, emotional coldness, detachment, and apathy. Affected individuals may be unable to form intimate attachments to others and simultaneously possess a rich and elaborate but exclusively internal fantasy world. Other associated features include stilted speech, a lack of deriving enjoyment from most activities, feeling as though one is an "observer" rather than a participant in life, an inability to tolerate emotional expectations of others, apparent indifference when praised or criticized, a degree of asexuality, and idiosyncratic moral or political beliefs.

<span class="mw-page-title-main">Anhedonia</span> Inability to feel pleasure

Anhedonia is a diverse array of deficits in hedonic function, including reduced motivation or ability to experience pleasure. While earlier definitions emphasized the inability to experience pleasure, anhedonia is currently used by researchers to refer to reduced motivation, reduced anticipatory pleasure (wanting), reduced consummatory pleasure (liking), and deficits in reinforcement learning. In the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), anhedonia is a component of depressive disorders, substance-related disorders, psychotic disorders, and personality disorders, where it is defined by either a reduced ability to experience pleasure, or a diminished interest in engaging in previously pleasurable activities. While the International Statistical Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) does not explicitly mention anhedonia, the depressive symptom analogous to anhedonia as described in the DSM-5 is a loss of interest or pleasure.

<span class="mw-page-title-main">Avoidant personality disorder</span> Personality disorder

Avoidant personality disorder (AvPD) or Anxious personality disorder is a Cluster C personality disorder characterized by excessive social anxiety and inhibition, fear of intimacy, severe feelings of inadequacy and inferiority, and an overreliance on avoidance of feared stimuli as a maladaptive coping method. Those affected typically display a pattern of extreme sensitivity to negative evaluation and rejection, a belief that one is socially inept or personally unappealing to others, and avoidance of social interaction despite a strong desire for it. It appears to affect an approximately equal number of men and women.

Schizotypal personality disorder, also known as schizotypal disorder, is a cluster A personality disorder. The Diagnostic and Statistical Manual of Mental Disorders (DSM) classification describes the disorder specifically as a personality disorder characterized by thought disorder, paranoia, a characteristic form of social anxiety, derealization, transient psychosis, and unconventional beliefs. People with this disorder feel pronounced discomfort in forming and maintaining social connections with other people, primarily due to the belief that other people harbor negative thoughts and views about them. Peculiar speech mannerisms and socially unexpected modes of dress are also characteristic. Schizotypal people may react oddly in conversations, not respond, or talk to themselves. They frequently interpret situations as being strange or having unusual meanings for them; paranormal and superstitious beliefs are common. Schizotypal people usually disagree with the suggestion that their thoughts and behaviors are a 'disorder' and seek medical attention for depression or anxiety instead. Schizotypal personality disorder occurs in approximately 3% of the general population and is more commonly diagnosed in males.

In psychology, schizotypy is a theoretical concept that posits a continuum of personality characteristics and experiences, ranging from normal dissociative, imaginative states to extreme states of mind related to psychosis, especially schizophrenia. The continuum of personality proposed in schizotypy is in contrast to a categorical view of psychosis, wherein psychosis is considered a particular state of mind, which the person either has or does not have.

<span class="mw-page-title-main">Emotional detachment</span> Inability and/or disinterest in emotionally connecting to others

In psychology, emotional detachment, also known as emotional blunting, is a condition or state in which a person lacks emotional connectivity to others, whether due to an unwanted circumstance or as a positive means to cope with anxiety. Such a coping strategy, also known as emotion focused-coping, is used when avoiding certain situations that might trigger anxiety. It refers to the evasion of emotional connections. Emotional detachment may be a temporary reaction to a stressful situation, or a chronic condition such as depersonalization-derealization disorder. It may also be caused by certain antidepressants. Emotional blunting, also known as reduced affect display, is one of the negative symptoms of schizophrenia.

A spectrum disorder is a disorder that includes a range of linked conditions, sometimes also extending to include singular symptoms and traits. The different elements of a spectrum either have a similar appearance or are thought to be caused by the same underlying mechanism. In either case, a spectrum approach is taken because there appears to be "not a unitary disorder but rather a syndrome composed of subgroups". The spectrum may represent a range of severity, comprising relatively "severe" mental disorders through to relatively "mild and nonclinical deficits".

A loner is a person who does not seek out, actively avoids, or fails to maintain interaction with other people. There are many potential reasons for their solitude. Intentional reasons include introversion, mysticism, spirituality, religion, or personal considerations. Unintentional reasons involve being highly sensitive or shy. More than one type of loner exists, and those who meet the criteria for being called loners often actually enjoy social interactions with people but display a degree of introversion which leads them to seek out time alone.

The trait of extraversion and introversion are a central dimension in some human personality theories. The terms introversion and extraversion were introduced into psychology by Carl Jung, though both the popular understanding and current psychological usage are not the same as Jung's original concept. Extraversion tends to be manifested in outgoing, talkative, energetic behavior, whereas introversion is manifested in more reflective and reserved behavior. Jung defined introversion as an "attitude-type characterised by orientation in life through subjective psychic contents", and extraversion as "an attitude-type characterised by concentration of interest on the external object".

<span class="mw-page-title-main">Autism spectrum</span> Neurodevelopmental disorder

Autism, formally called autism spectrum disorder (ASD) or autism spectrum condition (ASC), is a neurodevelopmental disorder marked by deficits in reciprocal social communication and the presence of restricted and repetitive patterns of behavior. Other common signs include difficulty with social interaction, verbal and nonverbal communication, along with perseverative interests, stereotypic body movements, rigid routines, and hyper- or hyporeactivity to sensory input. Autism is clinically regarded as a spectrum disorder, meaning that it can manifest very differently in each person. For example, some are nonspeaking, while others have proficient spoken language. Because of this, there is wide variation in the support needs of people across the autism spectrum.

<span class="mw-page-title-main">Imprinted brain hypothesis</span> Conjecture on the causes of autism and psychosis

The imprinted brain hypothesis is an unsubstantiated hypothesis in evolutionary psychology regarding the causes of autism spectrum and schizophrenia spectrum disorders, first presented by Bernard Crespi and Christopher Badcock in 2008. It claims that certain autistic and schizotypal traits are opposites, and that this implies the etiology of the two conditions must be at odds.

Social problem-solving, in its most basic form, is defined as problem solving as it occurs in the natural environment. More specifically it refers to the cognitive-behavioral process in which one works to find adaptive ways of coping with everyday situations that are considered problematic. This process in self-directed, conscious, effortful, cogent, and focused. Adaptive social problem-solving skills are known to be effective coping skills in an array of stressful situations. Social problem-solving consists of two major processes. One of these processes is known as problem orientation. Problem orientation is defined as the schemas one holds about problems in everyday life and ones assessment of their ability to solve said problems.

Evolutionary psychiatry, also known as Darwinian psychiatry, is a theoretical approach to psychiatry that aims to explain psychiatric disorders in evolutionary terms. As a branch of the field of evolutionary medicine, it is distinct from the medical practice of psychiatry in its emphasis on providing scientific explanations rather than treatments for mental disorder. This often concerns questions of ultimate causation. For example, psychiatric genetics may discover genes associated with mental disorders, but evolutionary psychiatry asks why those genes persist in the population. Other core questions in evolutionary psychiatry are why heritable mental disorders are so common how to distinguish mental function and dysfunction, and whether certain forms of suffering conveyed an adaptive advantage. Disorders commonly considered are depression, anxiety, schizophrenia, autism, eating disorders, and others. Key explanatory concepts are of evolutionary mismatch and the fact that evolution is guided by reproductive success rather than health or wellbeing. Rather than providing an alternative account of the cause of mental disorder, evolutionary psychiatry seeks to integrate findings from traditional schools of psychology and psychiatry such as social psychology, behaviourism, biological psychiatry and psychoanalysis into a holistic account related to evolutionary biology. In this sense, it aims to meet the criteria of a Kuhnian paradigm shift.

Sex and gender differences in autism exist regarding prevalence, presentation, and diagnosis.
