Focus of the research at the department of Biological Psychology is the analysis of individual differences in health, cognition, normal and abnormal behaviour. We study the genetic and biological basis of individual differences in human behaviour using approaches from genetic epidemiology, psychophysiology and molecular genetics.
The department maintains the Netherlands Twin Register which was established in 1987 and remains an important resource for research in (behavioural) genetics. The NTR collects data from twin-families (twins, sibs, parents, spouses, offspring). In the NTR-Biobank project biological material is collected. Longitudinal data are collected by way of surveys.
Over 60 PhD students have used 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 ( has been established to address the special needs of twins and multiples.
