Disrupted attention to eye gaze and abnormal visual processing of faces are two attractive candidate hypotheses about core autistic deficits. This study will test hypotheses about disrupted attention to eye gaze in autism by adapting a classical visual attention task (comparing gaze cues to simple box and arrow cues) in 60 children, ages 9-12 (half with high-functioning autism and half typically developing). A second task will explore the potential failure of the eye region of the face to capture attention in autistic individuals. These pilot behavioral experiments will set the stage for future neuroimaging studies. This study of the psychological and brain bases of autism will help characterize aspects of the most serious psychiatric disorder of childhood in ways that will make autism more amenable to genetic, screening, and interventional studies. As such it will improve early identification, which is crucial for improving outcome in affected individuals.
