Social-emotional development of infants at risk for autism spectrum disorders  

Infant siblings of children with ASD exhibit substantial variability in their social-communicative outcomes: some manifest behaviors consistent with an autism spectrum diagnosis, others exhibit less severe symptoms such as language delay, and others evidence no detectable disorder. This project will examine the extent to which early impairments in specific attentional and affective mechanisms explain the behavioral heterogeneity that is observed in these high-risk children. This study will focus specifically on the domains of attention coordination and positive affective competencies and examine their development across the first two years of postnatal life (i.e., from 6 to 18 months) and their relation to later social and communicative outcomes at age 24 and 36 months. This offers an ideal opportunity to learn about the earliest signs of autism as well as the development, manifestation, and boundaries of the broader autism phenotype. Project Status
