Temporal processing deficits in high‐functioning children with autism

Abstract

It is well known that complex functions (e.g. perception, attention, memory, emotions, social interactions and language) are usually disturbed in autism. As these functions are characterized by specific temporal patterns, the present study examined whether children with autism show typical temporal processing in the time domain of a few seconds. Using a temporal-reproduction paradigm, we found that they were unable to link their responses to stimulus duration. Independently of stimulus duration, they reproduced auditory or visual stimuli with the same response duration of, on average, 3 s. These results demonstrate important deficits in duration judgment in individuals with autism. As other experiments provide evidence for a temporal processing platform of approximately 2-3 s in normal individuals, this platform may be preserved in a residual form in autism.
