| Outline of Final Research Achievements |
Despite the emphasis of autism spectrum disorders as a continuum of atypical social behaviors and the sexual heterogeneity of phenotypic manifestations, whether gaze and face processing constitutes an autistic endophenotype in both sexes remains unclear. Using the Autism-Spectrum Quotient and behavioral (face and gaze) tasks, here we examined whether sex-differential relationships between autistic traits and behavior might exist in a normal population. We found that a significant correlation between gaze perception and autistic traits was observed in male, but not female participants. In addition, correlations were not found for low-level geometry and face recognition/memory tasks in both male and female, indicating the relationship is confined to gaze. Our findings suggest that direct-gaze perception may not constitute an autistic endophenotype in both sexes, and highlight the importance of sex differences when considering relationships between autistic traits and behaviors.
