Abused, neglected, and nonmaltreated preschoolers' ability to discriminate emotions in others: the effects of IQ.

Sixty children between the ages of 3 and 5 participated in this study of children's ability to discriminate emotions in others. Twelve children were identified as neglected, and eight were identified as abused. Two additional groups of nonmaltreated children included one comparable on IQ and one with significantly higher intelligence. All children were given three tests: The Peabody Picture Vocabulary Test, the Borke Interpersonal Awareness Test and the Rothenberg Social Sensitivity Test. The results showed that normal children with the higher IQ were significantly better able to identify and discriminate other people's emotions from picture stories than were the other groups of children, who were not different from one another on any of the measures. Furthermore, when IQ was covaried in the ANOVAS, all group-differences disappeared. It was suggested that previous studies demonstrating inferior performance on measures of social cognition by maltreated children may have been due to the failure to control for IQ.
