First, we conducted a review of all available literature on the concept of unconditional regard, and we integrated the literature into an overarching theoretical model. Second, we conducted studies with preschoolers, with the overarching aim of developing an experimental paradigm to manipulate the experience of unconditional regard. Third, we conducted an observational-longitudinal study on real-life experiences of unconditional regard, and how those experience shape children’s development. Fourth, we edited two special sections in leading journals (i.e. Child Development and Journal of Abnormal Psychology) to better understand how socialization shapes children’s views of themselves. Fifth, we presented our research for various audiences: parents, teachers, educators, policy makers, developmental psychologists, and social psychologists. Sixth, we disseminated findings through national and international media, radio shows, podcasts, public lectures, and interviews for newspapers and magazines. Seventh, we published in top-tier scientific journals (e.g. Child Development, Nature Human Behaviour) and popular scientific outlets (e.g. Behavioral Scientist). Eighth, we established a productive collaboration between Stanford University and the University of Amsterdam (e.g. co-advising PhD students, co-authoring grant proposals).
