Results of two studies investigating children's abilities to use different kinds of cues to infer another's affective state are reported in this paper. In the first study, 48 children (3, 4, and 6 to 7 years of age) were given three different kinds of tasks (interpersonal task, facial recognition task, and vocal recognition task). A cross-age comparison of their responses was then made. Improvement with age was shown on all three tasks. Facial recognition was the easiest task, while vocal recognition was the most difficult task for all age levels. When the patterns shown across tasks and emotions were examined, identification of the emotion "happy" was found to be easier with facial and situational cues, while identification of the emotions "sad" and "mad" was easier with vocal recognition cues. The youngest group showed "sad"-"mad" confusion with both facial and situational cues, while 4- and 6- to 7-year-olds showed this confusion only with situational cues. In the second study, the same tasks were given to a group of 35 preschoolers during their first year in a university-based preschool and again one year later. In general, findings for correct responses closely replicated the findings for the two youngest groups in the original study. These findings suggest that preschoolers make considerable progress in judging emotions on the basis of cues available in faces, voices, and situations. (Author/MP)
