Nancy Eisenberg, developmental psychologist at Arizona State University, talks with June Gruber of Yale about her decades of research on emotion regulation in children. Recorded for Yale's Experts in Emotion series, the interview opens with what drew Eisenberg to the study of emotion before moving into the core findings of her work, including how children learn to manage and express feelings and why early regulation skills matter for later social and behavioral outcomes. Eisenberg walks through the central discoveries that have shaped the field over her career, then turns to where she thinks the most promising open questions lie for future researchers. The conversation closes with her practical advice for students and early-career psychologists interested in studying emotion. The format is a structured one-on-one interview with chapter markers, not a classroom lecture, but the content is substantive and grounded in Eisenberg's own published research program.
