The purpose of the present study was to investigate the understanding of non-verbal communication by adults with mental retardation, and to examine the relation between their visual perception skills and the accuracy with which they identify others' expressions of emotions. Participants in the study, 124 adults with mild and moderate mental retardation (90 men, 34 women; average age, 20.6 years) and 128 college students without mental retardation (58 men, 70 women; aged 18-20 years), were asked to rate stimuli in which feelings of happiness, sadness, anger, or dislike were expressed. In all 3 experimental conditions, "voice only", "face only" (moving pictures on videotape), and "voice plus face" (moving pictures accompanied by sound), the adults with mental retardation identified the feelings less accurately than the college students did. In the "face only" and "voice plus face" conditions, happiness was identified more accurately than the other feelings. The adults with mental retardation identified the emotions in the "voice only" condition better than in the "face only" condition. The adults with mental retardation were more likely than the college students to confuse the expression of happiness with the expressions of anger and dislike. A positive relation was found in the participants with mental retardation between their visual perception skills, as measured on the Frostig Developmental Test of Visual Perception, and their identification of emotions in 2 of the 3 test conditions: "face" and "voice plus face".
