Asperger syndrome (AS), also known as Asperger's syndrome or Asperger's, is a diagnosis formerly used to describe a neurodevelopmental condition 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 considered a diagnosis. It was considered milder than other diagnoses which were merged into ASD due to relatively unimpaired spoken language and intelligence.
In psychology, theory of mind refers to the capacity to understand other people by ascribing mental states to them. A theory of mind includes the understanding that others' beliefs, desires, intentions, emotions, and thoughts may be different from one's own. Possessing a functional theory of mind is crucial for success in everyday human social interactions. People utilize a theory of mind when analyzing, judging, and inferring others' behaviors. The discovery and development of theory of mind primarily came from studies done with animals and infants. Factors including drug and alcohol consumption, language development, cognitive delays, age, and culture can affect a person's capacity to display theory of mind. Having a theory of mind is similar to but not identical with having the capacity for empathy or sympathy.
Paralanguage, also known as vocalics, is a component of meta-communication that may modify meaning, give nuanced meaning, or convey emotion, by using techniques such as prosody, pitch, volume, intonation, etc. It is sometimes defined as relating to nonphonemic properties only. Paralanguage may be expressed consciously or unconsciously.

The neurodiversity paradigm is a framework for understanding human brain function that recognizes the diversity within sensory processing, motor abilities, social comfort, cognition, and focus as neurobiological differences. This diversity falls on a spectrum of neurocognitive function. The neurodiversity paradigm argues that diversity in human cognition is normal and that some conditions generally classified as disorders, such as autism, are differences and disabilities that are not necessarily pathological.
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, as well as repetitive, restricted patterns of behavior. 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.
Social behavior is behavior among two or more organisms within the same species, and encompasses any behavior in which one member affects the other. This is due to an interaction among those members. Social behavior can be seen as similar to an exchange of goods, with the expectation that when you give, you will receive the same. This behavior can be affected by both the qualities of the individual and the environmental (situational) factors. Therefore, social behavior arises as a result of an interaction between the two—the organism and its environment. This means that, in regards to humans, social behavior can be determined by both the individual characteristics of the person, and the situation they are in.
Augmentative and alternative communication (AAC) encompasses the communication methods used to supplement or replace speech or writing for those with impairments in the production or comprehension of spoken or written language. AAC is used by those with a wide range of speech and language impairments, including congenital impairments such as cerebral palsy, intellectual impairment and autism, and acquired conditions such as amyotrophic lateral sclerosis and Parkinson's disease. AAC can be a permanent addition to a person's communication or a temporary aid. Stephen Hawking, probably the best-known user of AAC, had amyotrophic lateral sclerosis, and communicated through a speech-generating device.
The following outline is provided as an overview of and topical guide to autism:
Mind-blindness, mindblindness or mind blindness is a theory initially proposed in 1990 that claims that all autistic people have a lack or developmental delay of theory of mind (ToM), meaning they are unable to attribute mental states to others. According to the theory, a lack of ToM is considered equivalent to a lack of both cognitive and affective empathy. In the context of the theory, mind-blindness implies being unable to predict behavior and attribute mental states including beliefs, desires, emotions, or intentions of other people. The mind-blindness theory asserts that children who delay in this development will often develop autism.
Cognitive specialization suggests that certain behaviors, often in the domain of social communication, are passed on to offspring and refined to be maximally beneficial by the process of natural selection. Specializations serve an adaptive purpose for an organism by allowing the organism to be better suited for its habitat. Over time, specializations often become essential to the species' continued survival. Cognitive specialization in humans has been thought to underlie the acquisition, development, and evolution of language, theory of mind, and specific social skills such as trust and reciprocity. These specializations are considered to be critical to the survival of the species, even though there are successful individuals who lack certain specializations, including those diagnosed with autism spectrum disorder or who lack language abilities. Cognitive specialization is also believed to underlie adaptive behaviors such as self-awareness, navigation, and problem solving skills in several animal species such as chimpanzees and bottlenose dolphins.
Ray L. Birdwhistell was an American anthropologist who founded kinesics as a field of inquiry and research. Birdwhistell coined the term kinesics, meaning "facial expression, gestures, posture and gait, and visible arm and body movements". He estimated that "no more than 30 to 35 percent of the social meaning of a conversation or an interaction is carried by the words." Stated more broadly, he argued that "words are not the only containers of social knowledge." He proposed other technical terms, including kineme, and many others less frequently used today. Birdwhistell had at least as much impact on the study of language and social interaction generally as just nonverbal communication because he was interested in the study of communication more broadly than is often recognized. Birdwhistell understood body movements to be culturally patterned rather than universal. His students were required to read widely, sources not only in communication but also anthropology and linguistics. "Birdwhistell himself was deeply disappointed that his general communicative interests and goals were not appropriately understood." Collaborations with others, including initially Margaret Mead and Gregory Bateson, and later, Erving Goffman and Dell Hymes had huge influence on his work. For example, the book he is best known for, Kinesics and Context, "would not have appeared if it had not been envisaged by Erving Goffman" and he explicitly stated "the paramount and sustaining influence upon my work has been that of anthropological linguistics", a tradition most directly represented at the University of Pennsylvania by Hymes.
John D. Bonvillian (1948-2018) was a psychologist and associate professor - emeritus in the Department of Psychology and the Interdepartmental Program in Linguistics at the University of Virginia in Charlottesville, Virginia. He is the principal developer of Simplified Signs, a manual sign communication system designed to be easy to form, easy to understand and easy to remember. He is also known for his research contributions to the study of sign language, child development, psycholinguistics, and language acquisition.
Classic autism, also known as childhood autism, autistic disorder, (early) infantile autism, infantile psychosis, Kanner's autism, Kanner's syndrome, or (formerly) just autism, is a neurodevelopmental condition 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.
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. 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.
Autism, also called autism spectrum disorder (ASD), is a neurodevelopmental disorder characterized by symptoms of deficient reciprocal social communication and the presence of restricted, repetitive, and inflexible patterns of behavior. Autism generally affects a person's ability to understand and connect with others, as well as their adaptability to everyday situations, with its severity and support needs varying widely across the spectrum. For example, some are nonspeaking, while others have proficient spoken language.
The development of an animal model of autism is one approach researchers use to study potential causes of autism. Given the complexity of autism and its etiology, researchers often focus only on single features of autism when using animal models.
Nonverbal autism, also called nonspeaking autism, is a subset of autism spectrum disorder (ASD) where the person does not learn how to speak. One study has shown that 64% of autistic children who are nonverbal at age 5 are still nonverbal 10 years later.
Social (pragmatic) communication disorder (SPCD), also known as pragmatic language impairment (PLI), is a neurodevelopmental disorder characterized by difficulties in the social use of verbal and nonverbal communication. Individuals who are defined by the acronym "SPCD" struggle to effectively indulge in social interactions, interpret social cues, and may struggle to use words appropriately in social contexts.
Neural synchrony is the correlation of brain activity across two or more people over time. In social and affective neuroscience, neural synchrony specifically refers to the degree of similarity between the spatio-temporal neural fluctuations of multiple people. This phenomenon represents the convergence and coupling of different people's neurocognitive systems, and it is thought to be the neural substrate for many forms of interpersonal dynamics and shared experiences. Some research also refers to neural synchrony as inter-brain synchrony, brain-to-brain coupling, inter-subject correlation, between-brain connectivity, or neural coupling. In the current literature, neural synchrony is notably distinct from intra-brain synchrony—sometimes also called neural synchrony—which denotes the coupling of activity across regions of a single individual's brain.
