Examined children's and adults' ability to decode emotions in dance forms of expressive body movements and detect intensity differences in anger and happiness. Found that decoding ability exceeded chance for sadness by 4-year olds; sadness, fear, and happiness by 5-year olds; and all emotions by 8-year olds and adults. Children as young as 5 relied on emotion-specific movement cues in decoding intensity. (Author/KB)
