The current study examined whether increasing visual perceptual load also has less of an effect on auditory awareness in children with ASD. Participants performed either a high- or low load version of a line discrimination task. On a critical trial, an unexpected, task-irrelevant auditory stimulus was played concurrently with the visual stimulus. In contrast to typically developing (TD) children, children with ASD demonstrated similar detection rates across perceptual load conditions, and reported greater awareness than TD children in the high perceptual load condition. These findings suggest an increased perceptual capacity in children with ASD that operates across sensory modalities.
