Isaac Petersen

Isaac T. Petersen, Ph.D.

Principal Investigator

Dr. Isaac T. Petersen is interested in how children develop individual differences in adjustment, including behavior problems as well as competencies. He is particularly interested in the development of externalizing behavior problems and underlying self-regulation difficulties. Dr. Petersen's primary research interests include how children develop self-regulation as a function of bio-psycho-social processes including brain functioning, genetics, parenting, temperament, language, and sleep, and how self-regulation in turn influences adjustment and school readiness. A special emphasis of his work examines the neural development underlying the development of self-regulation, school readiness, and externalizing problems, with measures of electroencephalography (EEG) and event-related potentials (ERPs). He is also interested in ways to measure change over lengthy spans of development using different measures over time to account for changes in how constructs manifest with development (i.e., heterotypic continuity).
