Special interests are highly focused interests common in autistic people; [1] they are more intense than typical interests, such as hobbies, [2] and may take up much of a person's free time. A person with a special interest will often hyperfocus on their special interest for hours, want to learn as much as possible on the topic, [3] collect related items, [4] and incorporate their special interest into play [5] and art. [6] Some interests are more likely to be seen as special interests if they are particularly unusual, specific, or niche. [2] Autism rights advocates and psychologists say this binary of acceptable "passions" and pathologised "obsessions" is unfair. [7] [8] Terms like circumscribed interests, [9] obsessions, or restricted interests [10] have historically been used to describe special interests, but these terms are discouraged by autism rights advocates. [7]

Contents

Special interests are sometimes confused with hyperfixations. [11] Hyperfixations are short-lived periods of strong interest in a subject over a few days to months which can occur in anyone (although are especially common in people with ADHD), [12] while special interests are an autistic trait and usually last years. [13] A person may hyperfixate on a special interest.

Occurrence and development

Around 75–90% of autistic people develop a special interest, [4] with some studies claiming as high as 95%. [14] Special interests are often developed between one and four years of age but may not develop until adulthood. [4] Many special interests start in children as a fascination with a particular object (e.g. Thomas the Tank Engine) and later develop into an interest in a specific topic (e.g. trains). [2] A special interest may change over time or last a person's whole life. [15] A 2014 survey found that the average number of special interests an autistic person has is 2, and the average longevity is 13 years. [2]

Intense special interests were written about by French psychiatrist Jean-Étienne Dominique Esquirol in 1827. [16] They were tied to a condition today considered autism by Soviet child psychiatrist Grunya Sukhareva (Груня Сухарева) in 1925. [17] [18] [19] In November 1940, Lauretta Bender and Paul Schilder published a paper focused on the topic. [20] Bender and Schilder's contemporaries like Hans Asperger and Leo Kanner also wrote about the matter, which was important to the development of autism awareness. [21]

Special interests were later one of the traits listed when autism first appeared in the DSM-III in 1980. [2] In 2024, special interests are listed as a diagnostic trait of autism in the current DSM-5-TR, described as "highly restricted, fixated interests that are abnormal in intensity or focus (e.g., strong attachment to or preoccupation with unusual objects, excessively circumscribed or perseverative interests)". [22]

Common areas of special interests are transportation, animals, sports, and popular culture. [23]

Engagement

Engaging in special interests can bring autistic people great joy [24] [25] and many autistic people spend large amounts of time engaged in their special interest. [26] In adults, engaging with special interests has been shown to have positive outcomes for mental health, [27] self-esteem, [28] and can be used to manage stress. [23]

Special interests can sometimes interfere with other areas of a person's life, such as school. [29] In children, incorporating a child's special interest into their education has been shown to improve learning outcomes, [30] [28] increase attention on learning topics [31] and teach behaviours such as sportsmanship. [32] Students have been shown to write better when writing about their special interest compared to a control topic. [33] A 2022 study showed 25% of autistic people who worked had employment in their area of special interest and that adults with employable special interests may have better employment outcomes. [26] Special interests may lead people to become child prodigies or savants in their area of interest. [23]

Social interaction

Encouraging discussion of a special interest can help autistic people develop social skills [23] and help them find social communities. [34] [35] Autism acceptance proponents encourage autistic people to embrace their special interests, as long as they are not interfering with other parts of a person's life. [36] Special interests can be used by autistic people as a way to understand the world and allistic people. [37]

Special interests may lead to social difficulties if the person does not want to discuss any other topic, and conversations may become one-sided [2] especially when infodumping. [38] Some special interests may be viewed as unusual or bizarre, such as an interest in electricity pylons being seen as odder than an interest in horses or football teams. [23] Autistic people who are aware of this may deliberately stop themselves from talking about their special interest as a form of masking, [23] especially if they have been mocked for their interest in the past. [14] Other special interests may be seen as atypical for a person's age. [2] [39]

Examples

Environmental activist Greta Thunberg has credited her success to her special interests. [40] [41] She explained to The Guardian in 2021, "A lot of people with autism have a special interest that they can sit and do for an eternity without getting bored. It’s a very useful thing sometimes...[if] you feel you have a purpose, then it can be something you can use for good, and I think I'm doing that now". [42]

Asperger syndrome (AS), also known as Asperger's syndrome or Asperger's, is a diagnostic label that has been used to describe a neurodevelopmental disorder characterized by significant difficulties in social interaction and nonverbal communication, along with restricted, repetitive patterns of behavior and interests. Asperger syndrome has been merged with other conditions into autism spectrum disorder (ASD) and is no longer a diagnosis in the WHO's ICD-11 or the APA's DSM-5-TR. It was considered milder than other diagnoses which were merged into ASD due to relatively unimpaired spoken language and intelligence.

High-functioning autism (HFA) was historically an autism classification to describe a person who exhibited no intellectual disability but otherwise showed autistic traits, such as difficulty in social interaction and communication. The term was often applied to verbal autistic people of at least average intelligence. However, many in medical and autistic communities have called to stop using the term, finding it simplistic and unindicative of the difficulties some autistic people face.

Self-stimulatory behavior, also known as "stimming" and self-stimulation, is the repetition of physical movements, sounds, words, moving objects, or other behaviors. Stimming is a type of restricted and repetitive behavior (RRB). Such behaviors are found to some degree in all people, but is especially intense and frequent in those with developmental disabilities, attention deficit hyperactivity disorder (ADHD) or autism. People diagnosed with sensory processing disorder are also known to potentially exhibit more stimming behaviors.

The autism-spectrum quotient (AQ) is a questionnaire published in 2001 by Simon Baron-Cohen and his colleagues at the Autism Research Centre in Cambridge, UK. Consisting of fifty questions, it aims to investigate whether adults of average intelligence have symptoms of autism spectrum conditions. More recently, versions of the AQ for children and adolescents have also been published.

<span class="mw-page-title-main">Societal and cultural aspects of autism</span>

Societal and cultural aspects of autism or sociology of autism come into play with recognition of autism, approaches to its support services and therapies, and how autism affects the definition of personhood. The autistic community is divided primarily into two camps: the autism rights movement and the pathology paradigm. The pathology paradigm advocates for supporting research into therapies, treatments, and/or a cure to help minimize or remove autistic traits, seeing treatment as vital to help individuals with autism, while the neurodiversity movement believes autism should be seen as a different way of being and advocates against a cure and interventions that focus on normalization, seeing it as trying to exterminate autistic people and their individuality. Both are controversial in autism communities and advocacy which has led to significant infighting between these two camps. While the dominant paradigm is the pathology paradigm and is followed largely by autism research and scientific communities, the neurodiversity movement is highly popular among most autistic people, within autism advocacy, autism rights organizations, and related neurodiversity approaches have been rapidly growing and applied in the autism research field in the last few years.

Asperger syndrome (AS) was formerly a separate diagnosis under autism spectrum disorder. Under the DSM-5 and ICD-11, patients formerly diagnosable with Asperger syndrome are diagnosable with Autism Spectrum Disorder. The term is considered offensive by some autistic individuals. It was named after Hans Asperger (1906–80), who was an Austrian psychiatrist and pediatrician. An English psychiatrist, Lorna Wing, popularized the term "Asperger's syndrome" in a 1981 publication; the first book in English on Asperger syndrome was written by Uta Frith in 1991 and the condition was subsequently recognized in formal diagnostic manuals later in the 1990s.

<span class="mw-page-title-main">Classic autism</span> Former neurodevelopmental disorder now classified under autism spectrum disorder

Classic autism, also known as childhood autism, autistic disorder, or Kanner's syndrome, is a formerly diagnosed neurodevelopmental disorder first described by Leo Kanner in 1943. It is characterized by atypical and impaired development in social interaction and communication as well as restricted, repetitive behaviors, activities, and interests. These symptoms first appear in early childhood and persist throughout life.

Autism spectrum disorder (ASD), or simply autism, is a neurodevelopmental disorder "characterized by persistent deficits in social communication and social interaction across multiple contexts" and "restricted, repetitive patterns of behavior, interests, or activities". Sensory abnormalities are also included in the diagnostic manuals. Common associated traits such as motor coordination impairment are typical of the condition but not required for diagnosis. A formal diagnosis requires that symptoms cause significant impairment in multiple functional domains; in addition, the symptoms must be atypical or excessive for the person's age and sociocultural context.

Autism-friendly means being aware of social engagement and environmental factors affecting Autistic people, with modifications to communication methods and physical space to better suit individuals' unique and special needs.

The history of autism spans over a century; autism has been subject to varying treatments, being pathologized or being viewed as a beneficial part of human neurodiversity. The understanding of autism has been shaped by cultural, scientific, and societal factors, and its perception and treatment change over time as scientific understanding of autism develops.

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

Discrimination against autistic people involves any form of discrimination, persecution, or oppression against people who are autistic.

<span class="mw-page-title-main">Autistic masking</span> Suppression of autistic behaviors

Autistic masking, also referred to as camouflaging, is the conscious or subconscious suppression of autistic behaviors and compensation of difficulties in social interaction by autistic people, with the goal of being perceived as neurotypical. Masking behavior is a learned coping strategy that can be successful from the perspective of some autistic people, but can also lead to adverse mental health outcomes.

Current research indicates that autistic people have higher rates of LGBTQ identities and feelings than the general population. A variety of explanations for the increased prevalence of LGBTQ identities have been proposed, such as prenatal hormonal exposure, which has been linked with sexual orientation, gender dysphoria and autism. Alternatively, autistic people may be less reliant on social norms and thus are more open about their orientation or gender identity. A narrative review published in 2016 stated that while various hypotheses have been proposed for an association between autism and gender dysphoria, they lack strong evidence.

<span class="mw-page-title-main">Double empathy problem</span> Psychological theory regarding individuals on the autism spectrum

The theory of the double empathy problem is a psychological and sociological theory first coined in 2012 by Damian Milton, an autistic autism researcher. This theory proposes that many of the difficulties autistic individuals face when socializing with non-autistic individuals are due, in part, to a lack of mutual understanding between the two groups, meaning that most autistic people struggle to understand and empathize with non-autistic people, whereas most non-autistic people also struggle to understand and empathize with autistic people. This lack of mutual understanding may stem from bidirectional differences in dispositions, and experiences between autistic and non-autistic individuals, as opposed to always being an inherent deficit.

<span class="mw-page-title-main">Employment of autistic people</span>

The employment of autistic people is a social issue. People with autism have one of the lowest employment rates among workers with disabilities, with between 76% and 90% of autistic people being unemployed in Europe in 2014 and approximately 85% in the US in 2023. Similarly, in the United Kingdom 71% of autistic adults are unemployed. This is despite the fact, that "approximately 50% of people with autism spectrum disorder (ASD) have an IQ in the average to high range and do not have any additional physical needs." Young autistic adults are the most unemployed group when compared to people with learning disabilities, intellectual disabilities, or speech/language impairment.
