Attribution of intent and role-taking: cognitive factors as mediators of aggression with people who have mental retardation.

An assessment task was devised to explore the attributional style and role-taking ability of 22 aggressive and 22 nonaggressive adults with moderate to mild mental retardation. Aggressive participants showed a hostile bias in their interpretation of others' intentions towards themselves within ambiguous interpersonal situations, although no difference was found across groups within clearly provocative situations. Furthermore, the role-taking ability of the aggressive participants was superior to the nonaggressive group, undermining the focus on global problems of interpersonal understanding as a causal factor of aggression for people with mental retardation.
