Dr. Widaman conducts research on the development of children, adolescents, and young adults in the context of the family and broader behavioral and cultural contexts. Key in this research is longitudinal analyses that help identify effects of parents on their children and of children on their parents. In research on mental abilities, Dr. Widaman studied the cognitive processes underlying numerical facility, especially as these processes change in nature and in speed of execution from childhood through early adulthood. He also studies the structure and development of adaptive behaviors of persons with mental retardation, particularly how parenting behaviors foster growth of adaptive behaviors. His quantitative work encompasses contributions to factor analysis, structural equation modeling, and item response theory, and he is currently working on reformulating the role of significance testing in regression analysis.
Dr. Widaman is a Fellow of the American Psychological Association, won the Cattell Award from the Society of Multivariate Experimental Psychology, and is on the editorial boards of seven journals, including Psychological Methods, Multivariate Behavioral Research, and Intelligence.
