Face perception and social cognitive development in early autism: A prospective longitudinal study from 3 months to 7 years of age.

Autism spectrum condition (ASC) is characterized by atypical attention to eyes and faces, but the onset and impact of these atypicalities remain unclear. This prospective longitudinal study examined face perception in infants who develop ASC (N = 22, female = 5, 100% White) compared with typically developing infants (N = 131, female = 65, 55.6% White), tracking social‐cognitive and ASC development through age seven. Reduced interest in direct gaze and eyes during infancy correlated with atypical development of adaptive behavior at age four and theory of mind at age seven. Principal component analyses revealed less integrated processing of facial features and eye‐gaze information in ASC infants, potentially impacting their childhood social functioning. These findings highlight the intertwined nature of social‐cognitive development and ASC. [ABSTRACT FROM AUTHOR]
