Perception is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment. All perception involves signals that go through the nervous system, which in turn result from physical or chemical stimulation of the sensory system. Vision involves light striking the retina of the eye; smell is mediated by odor molecules; and hearing involves pressure waves.
Asperger syndrome (AS), also known as Asperger's syndrome or Asperger's, was a diagnosis 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.
Attention or focus, is the concentration of awareness on some phenomenon to the exclusion of other stimuli. It is the selective concentration on discrete information, either subjectively or objectively. William James (1890) wrote that "Attention is the taking possession by the mind, in clear and vivid form, of one out of what seem several simultaneously possible objects or trains of thought. Focalization, concentration, of consciousness are of its essence." Attention has also been described as the allocation of limited cognitive processing resources. Attention is manifested by an attentional bottleneck, in terms of the amount of data the brain can process each second; for example, in human vision, less than 1% of the visual input data stream of 1MByte/sec can enter the bottleneck, leading to inattentional blindness.
Gestalt psychology, gestaltism, or configurationism is a school of psychology and a theory of perception that emphasises the processing of entire patterns and configurations, and not merely individual components. It emerged in the early twentieth century in Austria and Germany as a rejection of basic principles of Wilhelm Wundt's and Edward Titchener's elementalist and structuralist psychology.
A sensorium (/sɛnˈsɔːrɪəm/) is the apparatus of an organism's perception considered as a whole. It is the "seat of sensation" where it experiences, perceives and interprets the environments within which it lives. The term originally entered English from the Late Latin in the mid-17th century, from the stem sens- ("sense"). In earlier use it referred, in a broader sense, to the brain as the mind's organ. In medical, psychological, and physiological discourse it has come to refer to the total character of the unique and changing sensory environments perceived by individuals. These include the sensation, perception, and interpretation of information about the world around us by using faculties of the mind such as senses, phenomenal and psychological perception, cognition, and intelligence.
Sir Simon Philip Baron-Cohen is a British clinical psychologist and professor of developmental psychopathology at the University of Cambridge. He is the director of the university's Autism Research Centre and a Fellow of Trinity College.
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 differences. The neurodiversity paradigm argues that diversity in neurocognition is part of humanity and that some neurodivergences generally classified as disorders, such as autism, are differences and disabilities that are not necessarily pathological. Neurotypical individuals are those who fall within the average range of functioning and thinking.
The following outline is provided as an overview of and topical guide to autism:
The University of North Carolina TEACCH Autism Program creates and disseminates community-based services, training programs, and research for individuals of all ages and skill levels with autism spectrum disorder (ASD), to enhance the quality of life for them and their families across the lifespan.
The weak central coherence theory (WCC), also called the central coherence theory (CC), suggests that a specific perceptual-cognitive style, loosely described as a limited ability to understand context or to "see the big picture", underlies the central issue in autism and related autism spectrum disorder. Autism is a neurodevelopmental disorder characterized by impaired social interaction and communication, repetitive behaviours, restricted interests, and sensory processing issues.
Michael John Lesser was a mathematical philosopher and political activist.
Anna Jean Ayres was an American occupational therapist, educational psychologist and advocate for individuals with special needs. She became known for her work on sensory integration (SI) theory.
Gunilla Gerland is a Swedish author and lecturer on the topic of autism. Her written works include Secrets to Success for Professionals in the Autism Field: An Insider's Guide to Understanding the Autism Spectrum, the Environment and Your Role and her autobiography A Real Person: Life on the Outside.
Perceptual load theory is a psychological theory of attention. It was presented by Nilli Lavie in the mid-nineties as a potential resolution to the early/late selection debate.
Caetextia is a term and concept first coined by psychologists Joe Griffin and Ivan Tyrrell to describe a chronic disorder that manifests as a context blindness in people on the autism spectrum. It was specifically used to designate the most dominant manifestation of autistic behaviour in higher-functioning individuals. Griffin and Tyrell also suggested that caetextia "is a more accurate and descriptive term for this inability to see how one variable influences another, particularly at the higher end of the spectrum, than the label of 'Asperger's syndrome'".
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 is a learned coping strategy that can be successful from the perspective of autistic people, but can also lead to adverse mental health outcomes.
Dinah Karen Crawshay Murray was a writer, educator and campaigner for autistic people. She collaborated in developing the theory of monotropism as a way of explaining autism in terms of a tendency to focus intensely on a subject.
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 understanding may stem from bidirectional differences in dispositions, and experiences between autistic and non-autistic individuals, as opposed to always being an inherent deficiency.
Damian Elgin Maclean Milton is a British sociologist and social psychologist who specialises in autism research and is an autism rights advocate. He is a lecturer at the University of Kent as well as a consultant for the United Kingdom's National Autistic Society and has academic qualifications in sociology, psychology, philosophy, and education.
Luke Beardon is an English academic in the field of autism studies. As of March 2024, he is a Senior Lecturer with The Autism Centre at Sheffield Hallam University, as well as a service coordinator with the National Autistic Society. He received a Doctor of Education degree from Sheffield Hallam University.
