| Abstract: | Five studies investigated the young infant's ability to produce identifiable emotion expressions as defined in differential emotions theory. Trained judges applied emotion-specific criteria in selecting expression stimuli from videotape recordings of 54 1–9 mo old infants' responses to a variety of incentive events, ranging from playful interactions to the pain of inoculations. Four samples of untrained Ss (130 undergraduates and 62 female health service professionals) confirmed the social validity of infants' emotion expressions by reliably identifying expressions of interest, joy, surprise, sadness, anger, disgust, contempt, and fear. Brief training resulted in significant increases in the accuracy of discrimination of infants' negative emotion expressions for low-accuracy Ss. Construct validity for the 8 emotion expressions identified by untrained Ss and for a consistent pattern of facial responses to unanticipated pain was provided by expression identifications derived from an objective, theoretically structured, anatomically based facial movement coding system.
