Quantitative Psychology and Individual Differences
The Research Group Quantitative Psychology and Individual Differences focuses on the interplay between substantive-psychological research and the development of novel formal models (including associated procedures for model estimation and testing). On the basis of substantive questions new formal models are being developed; in turn, these models are estimated and tested in substantive research, and contribute there to a breeding ground for the formulation of new substantive questions.
Central families of models we focus on include generalized (non)linear mixed models, clustering models, dynamic process and reaction time models, time series models, and models for multiway and multiblock data. Current substantive research themes include: (1) the study of the time dynamics of emotions and its association with psychological well-being (with questions such as: How do people move within an affective space and what does this tell us about somebody’s mental health?), (2) the unravelling of processes at the basis of emotions and emotion-related behavior (with questions such as: Does low control lead to aggressive or avoidant behavior tendencies?), and (3) the identification of subgroups of clients that differ with regard to the type of treatment they most benefit from.
The research group takes part in the Interuniversity Graduate School of Psychometrics and Sociometrics.
