🧠 Psychology By CampusDown Wiki Editorial Team Last updated October 15, 2026

Autism spectrum disorder

DSM-5 (2013) merged autistic disorder, Asperger's disorder and related diagnoses into autism spectrum disorder. Criteria are persistent deficits in social communication and interaction, and restricted, repetitive patterns of behaviour, interests or activities, including sensory differences, present from early development. Severity is coded at levels 1 to 3 by support needs.

Savant syndrome

Savant syndrome is a developmental disability combined with remarkable skills in a narrow area such as memory, calendar calculation, arithmetic, music, art or mechanics. J. Langdon Down described it in 1887. Darold Treffert classified splinter, talented and prodigious savants. About half of savants are autistic, and roughly one in ten autistic people shows savant abilities.

Explanations

Weak central coherence (Frith): a processing bias toward detail over global context
Hyper-systemizing (Baron-Cohen): a strong drive to detect rules and patterns
Theory of mind differences: difficulty inferring others' mental states, used to explain social challenges
Compensation (Treffert): right-hemisphere compensation for left-hemisphere dysfunction

Myths

After the film Rain Man (1988), many assumed all autistic people have special talents, but most do not. Autism is a spectrum, and the neurodiversity perspective emphasises support built on individual strengths.
