Exploring the ‘fractionation’ of autism at the cognitive level

Abstract

Autism spectrum disorders are defined by difficulties across a range of areas - social and communication difficulties and restricted and repetitive behaviours and interests. It has been suggested that this triad of symptoms cannot be explained by a single cause at the genetic, neural or cognitive level. This article reviews the evidence for a ‘fractionable’ autism triad at the cognitive level, highlighting questions for future research.
