Individual Differences Lab

Psychology Lab at The University of Tulsa





112 Lorton Hall

The Individual Differences Lab is a branch of the Institute for Biochemical and Psychological Study of Individual Differences (IBPID) at the University of Tulsa. Our lab focuses broadly on measurement and application of individual differences, such as our research on the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF). Specifically, lab advisors, Drs. Allan Harkness and John McNulty have created a five-factor personality model (known as the Personality Psychopathology Five; PSY-5) using the MMPI-2-RF. More recent projects have focused on applying individual differences science to adaptive psychological systems (see Harkness, Reynolds, and Lilienfeld, 2014). Our current focus has been interdisciplinary collaboration on a project using multiple personality measures collected over multiple days to create richly assessed individuals. These assessments are then provided as a phenotype to other departments to help elucidate the genetics of individual differences. In collaboration with other labs in IBPID, we recently applied for an R-21 grant from the National Institute of Mental Health to helps us fund our research on high precision measurement of psychoticism and its underlying genetics.
