This pilot study aimed to examine whether individuals with autism spectrum disorder (ASD) have face recognition deficits in either their central or peripheral vision or both of these. Ten individuals with ASD and 10 individuals with typical development (TD) were asked to observe a picture of a face with expression that was presented in either the central or peripheral visual field for 160 ms and then to distinguish whether the face was presenting a “happy” or “angry” expression, by pressing the corresponding one of the two labelled buttons. Using an eye tracker, each participant’s vision was confirmed during each trial. Subsequently, upon the performance of the next task series, the stimuli were substituted with numerals (0–9) and their names (zero–nine). Results showed that, in the face recognition task, individuals with ASD demonstrated significantly longer reaction time to stimuli in both their central and peripheral vision compared to individuals with TD. In addition, individuals with ASD gave significantly fewer correct answers for stimuli in their peripheral vision. In the numeral recognition task, no difference was found between the two groups |
