Longitudinal changes of brain and behavior
137
Conclusion
This study set out to test longitudinal changes in neural systems underlying social evaluation and aggression regulation, and its relation to behavioral outcomes. We found an increase in behavioral control across childhood, as behavioral aggression decreased over time and DLPFC activation was related to decreased behavioral aggression. Notably, children that showed larger increases in DLPFC activity within childhood also displayed the largest longitudinal decrease in behavioral aggression. These results gain in our understanding on how the developing brain processes social feedback and suggest that the DLPFC might serve as emotion regulation mechanisms in terms of negative social feedback. However, it remains unknown how these results relate to actual, real- life social interactions such as social media use. Novel approaches are needed to bring together both real-life social media monitoring, as well as innovative experimental neuroimaging as this will provide cutting edge research and can provide insights through a neuro-mechanistic approach.
