Looking at other children's interactions provides rich learning opportunities for a small
child. How children with autism look at other children is largely unknown. Using eyetracking,
we studied gaze performance in children with autism and neurotypical
comparison children while they were watching videos of semi-naturalistic social
interactions between young children. Using a novel, bottom-up approach we identified
event-related measures that distinguished between groups with high accuracy. The
observed effects remained in a subset of the total sample matched on IQ, and were
replicated across several different stimuli. The described method facilitates the
detection of meaningful patterns in complex eye-tracking data. Also, the approach
significantly improves visualization, which will help investigators understand, illustrate,
and generate new hypotheses.
