Face processing deficits are characteristic of autism spectrum conditions. However, event-related potential studies of autism spectrum conditions have found inconsistent results for the face selective N170 component. In this study, 15 adult males with autism spectrum conditions and 15 matched, typically developing controls completed a task in which pictures of faces were either attended to or ignored. In the control group, the N170 was larger when faces were attended to. However, there was no such modulation in the autism spectrum conditions group. This finding helps clarify the results from the earlier eventrelated potential studies of face processing in autism spectrum conditions and suggests that visual attention does not enhance face processing in autism spectrum conditions as it does in typical development.
