Psychologist Roy Baumeister of Florida State University discusses his research on self-regulation and emotion in this interview from Yale's Experts in Emotion series, directed by June Gruber. Baumeister explains what drew him to studying emotion, then walks through central findings from his work, including ideas connected to willpower and self-control as limited resources that interact with emotional states. He addresses where he sees the field of emotion research heading next and closes with practical advice for students or researchers hoping to enter the field. The format is a structured interview rather than a classroom lecture, moving through introduction, research history, future directions, and career advice in under twenty minutes, giving a compact but substantive look at one researcher's take on why self-control depletes and how emotion factors into that process.
