Abstract

The present study used the Dot-Probe paradigm to explore attentional allocation to faces compared with non-social images in high-functioning individuals with autism spectrum disorder (ASD) and typically developing controls. There was no evidence of attentional bias in either group when stimuli were presented at individually calculated sub-threshold levels. However, at supra-threshold presentation (200 ms), a face bias was found for control participants but not for those with ASD. These results add to evidence of reduced social interest in ASD, relative to controls, and further demonstrate when atypical social processing arises in the attentional time course.
