Attentional capacities in children with autism: is there a general deficit in shifting focus?

Series: Journal of Autism and Developmental Disorders 28 (6) 1998: 467-478. 1998Content type: text Media type: unmediated Carrier type: volume Subject(s): CHILDREN | ATTENTION DEFICIT DISORDERS | AUTISMSummary: Twenty-three children with autism and two control groups completed an attention battery comprising three versions of the continuous performance test (CPT) a digit cancellation task, the Wisconsin Card Sorting Test (WCST) and two novel computerised tests of shifting attention (i.e. the Same-Different Computerised Task and the Computerised Matching Task). Children with autism could focus on a particular stimulus and sustain this focus as indicated by their performance on the digit cancellation task and the CPT. Their performance on the WCST suggested problems in some aspects of shifting attention (i.e. disengaging attention) The autism group performed as well as controls on the Same-Different-Computerised-Task, however, that required successive comparisions between stimuli. This implies that they could, in fact, shift their attention continuously. In addition they did not differ from controls on the computerised matching task an analog of the WCST, suggesting that they do not have a general deficit in shifting attention. [AJ].
