ABSTRACT
Enhanced perception may allow for visual search superiority by individuals with Autism Spectrum Disorder (ASD), but does it occur over time? We tested high-functioning children with ASD, typically developing (TD) children, and TD adults in two tasks at three presentation rates (50, 83.3, and 116.7 ms/item) using rapid serial visual presentation. In the Color task, participants detected a purple target letter amongst black letter distractors. In the Category task, participants detected a letter amongst number distractors. Slower rates resulted in higher accuracy. Children with ASD were more accurate than TD children and similar to adults at the fastest rate when detecting color-marked targets, indicating atypical neurodevelopment in ASD may cause generalized perceptual enhancement relative to typically developing peers.
