Social Perception in Williams Syndrome
This project is part of an ongoing research program on Williams syndrome (WMS) funded since 1996 by the National Institute on Child Health and Human Development. The general goals of this research are to understand the neurocognitive bases of the social abilities and disabilities in children and adults with Williams syndrome.

Project Aims

People with WMS have good face processing skills and language ability. Additionally, they are more likely to notice subtle changes to social aspects of complex scenes, respond more empathically toward a person in distress, and appear to find social-affective stimuli less threatening on psychophysiological measures of arousal than other people. In our current line of research, we attempt to advance our understanding of the social phenotype of Williams syndrome and to explore the mechanisms that underlie the unique social-affective features that define this neurodevelopmental disorder by addressing the following questions:
  • Do people with Williams Syndrome interpret eye gaze information in the same way as other people?

  • Do people with Williams Syndrome show greater sensitivity to affective information in faces compared to others using implicit tasks?

  • Do people with Williams Syndrome attend more than other people to social information in dynamic scenes, as evidenced by eye-tracking data?

  • Do people with Williams Syndrome find social stimuli more rewarding than other people?

  • Do people with Williams Syndrome find social-affective stimuli less threatening, as measured by psychophysiological arousal, than other people?
