Little is known about how adults with autism spectrum disorder (ASD) process dynamic social scenes.We studied gaze behavior in 16 adults with ASD without intellectual impairment and 16 sex- and age-matched controls during passive scene processing.Adding more characters to a scene resulted in a drop in time spent looking at faces, and an increase in time spent looking at bodies (static trials) or off-person (dynamic trials) [Scene Type×AOI×Mode: F(2, 60)=3.54, p=.04, η2p=.11]. Unlike controls, adults with ASD showed only a small drop in the number of fixations made [Mode×Group: F(1, 30)=11.30, p=.002, η2p=.27] and no increase in the duration of face fixations [Mode×AOI×Group: F(2, 60)=3.50, p=.04, η2p=.11] when dynamic cues were added. Thus, particularly during dynamic trials, adults with ASD spent less time looking at faces and slightly more time looking off-person than did controls [Mode×AOI×Group: F(2, 60)=3.10 p=.05, η2p=.09]. Exhibiting more autistic traits and being less empathic were both associated with spending less time fixating on faces [.34<|r|<.55, p<.05].These results suggest that adults with ASD may be less sensitive to, or have more difficulty processing, dynamic cues—particularly those conveyed in faces. The findings demonstrate the importance of using dynamic displays in studies involving this clinical population.
