Abstract

Endogenous visual orienting among children with autism spectrum disorders (ASDs) and among typically developing (TD) children was examined using a Posner-type task that was modified to include social and nonsocial cues and targets to test hypotheses regarding information (social or nonsocial) and cue processing (long or short stimulus onset asynchronies (SOAs)). The findings suggest intact endogenous orienting to face and mixed face targets using hand and arrow cues among children with ASDs who were matched to typically developing children (TDC) on the basis of nonverbal mental age (MA) at approximately 8.5 years. The findings from this study challenge the notions of a social orienting impairment and of mechanical social orienting as the children with ASDs in this study demonstrated strong orienting effects in all conditions and social sensitivity in the long stimulus onset asynchrony (SOA) condition.
