Adolescence is a time of intense brain development in systems that support abstract thinking, social cognition and emotional feeling. It is also a time of intense social maturation, in which youths struggle to adapt to cultural norms and to reconcile the values and expectations of parents, peers, schools, and the broader society with their own desires and feelings. Yet, relatively little is known about how brain growth and social growth interact during this critical developmental stage, and how brain growth is influenced by the adoption of cultural norms for emotional behavior. This project examines how urban youths of color from immigrant families come to feel complex social emotions--emotions like admiration, inspiration, gratitude and compassion--in culturally appropriate, individually variable, ways. By combining neurobiological measures of social emotion processing with psychosocial interviews about the meaning youths make of social situations and personal experiences, the project seeks to transform knowledge about relations between adolescent brain and social development. The project involved 65 adolescent [participants][1] in two waves of laboratory visits roughly two years apart ([Wave 1][2]; [Wave 2][3]) and several [follow-up online surveys][4].
