Sophie Sweijen is a PhD candidate in the [SYNC lab][] at the ESSB department Developmental Neuroscience in Society. She focuses on the behavioral and neural developmental trajectories of prosocial behavioral and societal contributions during adolescence. Her work is part of the longitudinal ERC consolidator 'Brainlinks' project, in which 142 adolescents are followed over the course of three years. The project focuses on the development of prosocial behavior in young individuals, using a variety of techniques (e.g. fMRI, laboratory tasks and questionnaires). She also works on the new Spinoza-funded line of research on the wellbeing of young individuals during the COVID-19 pandemic. Here, she coordinates the project focusing on the impact of COVID-19 on adolescents' and students’ wellbeing, self-oriented and prosocial behavior, and the use of social media. Sophie completed her research master ‘Developmental Psychology’ at Leiden University in 2019. Her main interests lie in the social world of young individuals. During her studies, she assisted in multiple behavioral and fMRI studies investigating social learning, peer relations and risk taking in adolescence. For her master thesis, she focused on the developmental changes and individual differences in learning through social interactions.
