This multimethod project examines whether children (n=180; age 4) vary in their susceptibility to both positive and negative aspects of parenting, in real-time as well as in developmental time. With an experiment we test whether those children that are most affected by parents negative feedback, are also the ones that profit most from parents positive feedback. Through microlevel observations of parent-child interactions we examine whether children differ in their emotions and behaviors towards parents, depending on their susceptibility. Finally, using a longitudinal survey, we study whether childrenss susceptibility to parenting in parent-child interactions can predict childrens development over a year.
