In this lecture, Dr. Kevin Pelphrey discusses recent research, using functional magnetic resonance imaging to investigate the brain mechanisms involved in the typical and atypical development of social perception (the ability to understand the intentions and psychological dispositions of other people on the basis of biological motion cues) in typically developing children and children with autism.

Pelphrey, K. A., Morris, J. P., & McCarthy, G. (2005). Neural basis of eye-gaze processing deficits in autism. Brain, 128, 1038-1048.
Here, using event-related functional MRI (fMRI), we show that in autism, brain regions involved in gaze processing, including the superior temporal sulcus (STS) region, are not sensitive to intentions conveyed by observed gaze shifts. We conclude that lack of modulation of the STS region by gaze shifts that convey different intentions contributes to the eye gaze processing deficits associated with autism.
