Aging, cognitive complexity, and the fundamental attribution error.

Age differences in the prevalence and underpinnings of the fundamental attribution error were examined. Young, middle-aged, and older adults observed an actor providing responses to questions about political issues. In the no-choice condition, the actor was instructed how to respond, whereas in the choice condition, he was allowed to select his response. Consistent with previous research, middle-aged adults were less prone to the fundamental attribution error than were young and older adults. This was evidenced by their reduced tendency to make attitude attributions in the no-choice condition relative to the choice condition. Although high levels of both cognitive and attributional complexity were associated with reductions in attributional bias, complexity did not systematically account for the between-age-group differences in performance. It is suggested that the observed pattern of age effects is related to variations in both cognitive complexity and cognitive resources.
