My research focuses primarily on the development of the brain basis of social cognition and memory in infancy and early childhood.  In my lab, we use a combination of established behavioral paradigms and event-related potentials (ERP) to address questions about the development of explicit memory, shared attention, social and nonsocial reward processing and anticipation, and social relationships in typically developing infants and children, children with a diagnosis of Autism Spectrum Disorder (ASD), and infants who are at risk for later diagnosis of an ASD. In recent studies, we have tested the social motivation hypothesis (which posits that social problems in ASD may arise from differences in how social and nonsocial rewards are anticipated or processed). Our results suggest that whereas that typically developing children show greater brain activity when anticipating a social than a nonsocial reward, children with ASD show either the opposite pattern or no differences. A true test of the social motivation hypothesis, however, requires a developmental approach, where we can determine whether reward processing differences precede or follow the social problems seen in ASD. To accomplish this, we have been working to develop a reward anticipation paradigm that takes advantage of the ability of young children and even infants to anticipate events that are contingent on events that precede them. We are also working on ongoing studies on the emergence of shared attention in typically developing infants and infants at risk for developing ASD.
