Research
Leslie was a member of the Cognitive Development Unit (CDU) in London who proposed the theory of mind impairment in autism. In 1985 he published with Simon Baron-Cohen and Uta Frith the famous article Does the autistic child have a "theory of mind"?, in which it was suggested that children with autism have particular difficulties with tasks requiring the child to understand another person's beliefs and desires.

He is interested in the design of the cognitive system early in development. He has contributed a number of influential experimental studies and theoretical ideas on the perception of cause and effect, object tracking, and agent detection in infancy, the developmental role of modularity of mind, and the Theory of Mind Mechanism (ToMM) in the development of social cognition and its impairment in autism.

Family
His daughter, Sarah-Jane Leslie, is Dean of Graduate Studies at Princeton University.
