We examined whether this reflects differences in the development of patterns of fixation to eyes and mouths during face recognition. Children, adolescents, and adults (aged 7-30) with and without autism completed the Cambridge Face Memory Test while gaze was recorded. Average duration and number of fixations were calculated for eyes and mouth regions of interest, defined individually for each face image in the task. All groups and age groups made more and longer fixations to eyes than mouths. However, during face memorization, typically developing children and adults, but not adolescents, made more fixations to eyes than did their peers with autism. During face recognition, typically developing children and adults made shorter fixations on mouths than did their peers with autism; this pattern was reversed in adolescence, with adolescents with autism making more fixations to mouths than typically developing adolescents. Results suggest that group differences in patterns of fixations to faces change with age. Furthermore, different relationships between patterns of fixations and face recognition performance in typical development and autism suggest that these differences contribute, at least in part, to difficulties in autism.
