A closer look at preschoolers' freely produced labels for facial expressions.

Children's performance on free labeling of prototypical facial expressions of basic emotions is modest and improves only gradually. In 3 data sets (N = 80, ages 4 or 5 years; N = 160, ages 2 to 5 years; N = 80, ages 3 to 4 years), errors remained even when method factors (poor stimuli, unavailability of an appropriate label, or the difficulty of a production task) were controlled. Children's use of emotion labels increased with age in a systematic order: Happy, angry, and sad emerged early and in that order, were more accessible, and were applied broadly (overgeneralized) but systematically. Scared, surprised, and disgusted emerged later and often in that order, were less accessible, and were applied narrowly.
