Autism: Social and communication predictors in siblings  

This is a prospective, longitudinal study of the emergence of autism in infant siblings of children with autism (AU sibs) and low risk controls (tested at 6 months, 14, 24 and 36 months). This will be the first study of its kind to follow children at high risk for autism and related disorders from infancy to school age, and the first to prospectively and longitudinally compare linguistic functioning in autism, the broader autism phenotype (BAP), and specific language impairment (SLI).
