Personal profile
Research interests
My research broadly focuses on young children’s socio-moral development and moral reasoning. I investigate the various ways in which children come to navigate their social worlds and express their understanding of impartial moral norms.
My key areas of interest include:
- Children’s use and understanding of guilt displays
- Children’s sensitivity to moral justification
- Using novel research paradigms (e.g., posture change as an index of children’s emotional expression).
