The Neurocritic reviews a new study on gaze analysis that compares WS subjects to typically developing and autistic subjects.
"The WS subjects viewed faces for a longer duration than did their respective controls. Specifically, the WS group spent more time viewing the eyes, but not the mouth. Conversely, as has been demonstrated in previous studies, the participants with autism spent significantly less time looking at faces (eyes in particular) than did their controls.
Whilst individuals with autism spent a significantly smaller proportion of time than typical fixating on characters’ eyes (17% of face gaze time), those with WS spent significantly longer than typical fixating on the same region (58% of face gaze time). Visual attention to the eyes may be implicated in other divergent abilities in face perception, such as the interpretation of gaze cues and expressions, where individuals with WS are more proficient than those with autism."
