Slowed Search in the Context of Unimpaired Grouping in Autism: Evidence from Multiple Conjunction Search.

摘要: In multiple conjunction search, the target is not known in advance but defined only with respect to distractors a given search array, thus reducing contributions of bottom-up and top-down attentional perceptual processes during search. This study investigated whether superior visual skills typically demonstrated by individuals autism spectrum disorder (ASD) would be evident Thirty-two children ASD 32 age- nonverbal IQ-matched developing (TD) were administered task. Contrary findings from large majority studies on ASD, response times significantly slower than those their TD peers. Evidence slowed performance suggests that mechanisms responsible for other paradigms are available Although group failed exhibit performance, they showed efficient intertrial priming levels similar group. Efficient indicates participants able into distinct subsets. summary, while demonstrating grouping effects comparable exhibited peers, task, suggesting usual tasks specifically dependent and/or processes.
