Rianne Kok is an associate professor in team Youth & Family of the Erasmus School of Social and Behavioral Sciences (ESSB). She graduated at the University of Amsterdam in Clinical Neuropsychology and received her PhD at the Centre for Child and Family Studies at Leiden University. Her scientific work bridges a variety of disciplines, including clinical and cognitive psychology, and child and family studies. She is fascinated by the question why some children struggle more than others to act according to the social norms and values of their family, school, and society. Her research contributes to a better understanding of the social origins of children’s regulation of behavior, emotions, and cognition and their moral development in early and middle childhood. Rianne Kok specializes in using observational paradigms and coding schemes to study the interaction and (dyadic) regulation of parents and children. As PI in the ERC-funded Fami-LIES project, the NWO-funded Little Lies, Big Impact project, and the ClickNL-funded project TRUST GAME, she explores the impact of parental lying to children and child perspectives on this phenomenon. Rianne Kok is program director of the MA curriculum of Pedagogical Sciences, Recognition & Rewards officer of ESSB, and member of the management team of the Generation R Study.
