Abstract
Using eye-tracking technology we investigated visual scanning and pupillary responses to face and non-face stimuli in nine children (M = 49.6 months) with Autism Spectrum Disorder (ASD) compared to six mental-age and nine chronological-age matched children. The results revealed a significant decrease in visual scanning to landscapes. In addition, the ASD group showed pupillary constriction to children's faces, while control groups showed pupillary dilation. Visual scanning responses to landscapes had a negative correlation with the Behavior subscale of the Autism Diagnostic Observation Schedule-Generic for the ASD group. Potential use of these measures as early indicators of ASD is discussed.Keywords
