The Personality Across Development Lab’s main focus is to study child and adolescent personality and how it is related to behavior, how it affects children and adolescents relationships with their friends and parents, and how early personality traits may be indicators of later common behavioral problems. In addition, the PAD Lab is currently conducting research studying cross-cultural differences in internalizing/externalizing personality disorders, as well as adolescent gambling. Our research protocol includes genetic and hormone analysis, child and parent interviewing, survey/questionnaires, and other tasks meant to elicit common personality traits. The PAD Lab in the Clinical Research Services Center is a branch that was originally established in Toronto, and will be ongoing in Houston. The Tackett Lab will also be coordinating our research with other top research universities, including the University of Texas at Austin.
