Administered a videotaped nonverbal discrepancy test to children 9-15 yrs old. The test measured (a) decoding accuracy--the extent to which Ss were able to identify affects (positivity and dominance) from video (facial and body) cues and audio (content filtered and random spliced) cues; (b) discrepancy accuracy--the extent to which Ss recognized the degree of discrepancy between audio and video cues; and (c) video primacy--the extent to which Ss were more influenced by video than by audio cues. Older Ss benefited more than younger ones from the effects of retesting in their accuracy at decoding discrepant cues, especially for discrepant facial cues. All Ss showed significantly less video primacy after retesting, and older Ss displayed a trend for less body primacy after retesting. Older Ss showed less video primacy than younger ones in decoding extremely discrepant (as compared to slightly discrepant) audio and video nonverbal cues. Thus, although older children performed better than younger children at most nonverbal decoding tasks, the advantages of age were especially great for the decoding of the more discrepant channels.
