Marianne La France, a psychologist at Yale, sits down with fellow Yale researcher June Gruber for this installment of the Experts in Emotion interview series. La France traces her path into the psychology of emotion and lays out core findings from her research on how gender shapes emotional expression and perception, including work on smiling, nonverbal display rules, and the social costs and benefits attached to men's and women's emotional behavior. The bulk of the roughly twenty-minute conversation covers these central discoveries before La France turns to where she thinks the field is headed next. She closes with practical advice for students who want to study emotion. The format is a seated Q&A rather than a classroom lecture, but the content is substantive: an established researcher walking through her actual empirical program on gender differences in emotional communication, aimed at students and teachers rather than a general audience.
