The purpose of this project is to assess individual differences in social intelligence by applying the concept of working memory and its framework to the area of social intelligence. A new social intelligence task will be developed using a computer test in which individuals will be asked to identify (1) facial expressions in still photos and (2) the feelings of interviewees in short video clips under simulated social interactions. Several studies will be conducted to determine the validity, generalizability, and predictive and discriminant capability of this Multiple Social Tasks (MST) assessment. The generalizability tests will explore the association between social working memory and social skills with adult community samples that consist of a wide range of ages and diverse ethnic backgrounds among individuals. If the validity of the MST is successfully established through these studies, this new test can be a useful tool to reevaluate a spectrum of interpersonal adjustment problems including social impairment in high-functioning autism or Asperger's. The results of this project can also facilitate the development of innovative intervention programs that promote social skills.
