Within the University of Leiden, different funds are brought together to study the ability to learn from others in adolescence. Adolescence is a period of brain development, particularly in regions related to cognitive and social functioning. The sensitivity for social-affective processing in this period offers a huge opportunity for fostering learning in a period that is highly predictive of future success and well-being. In this project, longitudinal changes in classroom peer relationships are related to learning from others and academic achievement. Also, the neural correlates of observational learning in the context  of peer relationships is studied.
