The focus of research at the department of Biological Psychology is the analysis of individual differences in health, cognition, normal and abnormal behavior. We study the genetic and biological basis of individual differences in human behavior using approaches from genetic epidemiology, psychophysiology and molecular genetics.
The department maintains the Netherlands Twin Register (www.tweelingenregister.org) which was established in 1987 as an important resource for research in (behavioral) genetics. The NTR collects data from twin-families (twins, sibs, parents, spouses, offspring). In the NTR-Biobank project biological material. Longitudinal data are collected by surveys.
Nearly 50 PhD students have used the data collected by the NTR for their PhD thesis projects and many of these projects are done in close collaboration with international colleagues. In collaboration with the VU Medical Centre a special clinic (http://www.twinvumc.nl) has been established to address the special needs of twins and multiples.
