| Summary: | Introduction
Williams syndrome (WS) is a rare genetic disorder caused by a deletion at chromosome 7q1123. WS is associated with high empathy, relatively good face memory and low social anxiety. Despite these strengths, WS individuals typically have an intellectual disability, difficulties with visuospatial perception, non-social anxiety and complex social cognition. Attention to other’s eyes is crucial for adaptive social understanding. Consequently, eyes trigger quick and automatic gaze shifts in typically developing individuals. It is not known whether this process is atypical in WS.
Objectives
To examine visual attention to other’s eyes in Williams syndrome.
Methods
Individuals with WS (n = 35; mean age 23.5 years) were compared to controls (n = 167) in stratified age groups (7 month, 8-12 years, 13-17 years, adults). Participants were primed to look at either the eyes or the mouth of human faces. The latency and likelihood of a first gaze shift from, or to the eyes, was measured with eye tracking.
Results
WS individuals were less likely, and slower to orient to the eyes than typically developing controls in all age groups from eight years of age (all p <.001), but did not differ from 7 months old infants. In contrast to healthy individuals from eight years and above, WS individuals did not show a preference to orient towards the eyes relative to the mouth.
Conclusions
Despite the hyper-social behavioral phenotype, WS is associated with reduced attention to other’s eyes during early stages of processing. This could contribute to the difficulties with complex social cognition observed in this group.
