When people describe feeling “angry” or “distressed” or “dejected,” what do they really mean? Psychologists vigorously debate whether the words individuals use to describe their emotions actually reflect fixed states in the brain, or are merely convenient fictions for talking about feelings. “Are anger, sadness, and disgust” really distinct, universal emotions, asks Erik Nook, a fourth-year doctoral student in clinical psychology, “or is it the case that, because we have learned different concepts for different emotions, we produce those emotions?” Nook particularly wants to understand why some people seem to have more precise, granular emotional concepts—they distinguish among feeling disappointed, frustrated, or discouraged, for example—while others describe a general, undifferentiated negativity.
Disentangling what emotional concepts mean, and how people understand them, is part of Nook’s work with Leah Somerville, an associate professor of psychology whose lab focuses on how the mind develops in adolescence. A new paper in Psychological Science by Nook, Somerville, and colleagues at the University of Washington examines how emotional differentiation (people’s ability to separate emotional experiences into different types) changes from childhood into early adulthood.
