During the transition from childhood to emerging adolescence (approximately between the ages of 7-14-years-old) peer relations become more salient. Social emotion regulation, i.e., regulating emotions in social situations, for example after receiving (negative) peer feedback, is an important prerequisite for developing and maintaining peer relations. A broad range of literature has shown that receiving negative social feedback can result in reactive aggression. Recent studies additionally have shown that regulating such aggression is related to neural activation, and both behavioral and neural responses to social emotion regulation develop across childhood and adolescence. However, existing research has focused largely on group-based averages, obscuring meaningful individual variation in development. This ‘aggregate approach’ needlessly eliminates rich information in the form of within-participant variability. To move toward a more nuanced understanding of neurocognitive changes, developmental neuroimaging studies need to characterize individual differences as a variable of interest. Therefore, the current study will specifically examine individual differences in developmental trajectories of social emotion regulation. Moreover, to understand the underlying brain mechanisms, we will examine how developmental trajectories of aggression regulation following negative social feedback relate to functional brain development. To address individual variations of developmental trajectories, we will use multi-level models using longitudinal data across three waves during childhood and emerging adolescence. |
