Recent research has documented impaired ability to resist interference from visual distractors in individuals with autism spectrum disorder (ASD) and suggests that this phenomenon may be more pronounced in young versus older children (Christ et al., "Neuropsychology" 25(6):690-701, 2011). The present study extends previous findings by…

In the present study, typically developing…
