WebThis study investigated top-down modulation of bottom-up attentional capture in children with autistic spectrum disorders (ASDs) and in a typically developing (TD) comparison group using a spatial-cuing task (Experiment 1) and a series of visual search tasks (Experiment 2) employing task-irrelevant distractors. WebFor the subsequent P1 component, attentional modulations were clearly expressed and remained unaffected by these deviations. Collectively, these results suggest that spatial attention, unlike load or task relevance, can exert dissociable top-down modulatory effects at the C1 and P1 levels.
