An important reaction to individuals involved in problem solving is detecting the accuracy of their responses. Prior research has established that young adults are accurate in estimating correctness to responses on the Wechsler Adult Intelligence Scale (WAIS). These findings were extended to the elderly; also considered was whether ability-extraneous variables (e.g., fatigue) influence either accuracy in judging correctness, or IQ score. The WAIS was administered to 44 community dwelling elderly citizens in a counterbalanced manner to control for motivational influences. The examinees' IQs and estimations of correctness were measured. Materials included standard WAIS protocols and forms on which the examinees wrote a "+" or "-" after each response to indicate feelings of correctness ("+") or incorrectness ("-"). Older examinees were highly accurate in their feelings of correctness. Analyses of variance and covariance indicated order of presentation significantly influenced accuracy in reporting correctness. While IQ score was not affected by order of presentation, mean Performance IQ score was significantly lower than mean Verbal IQ score. Findings suggest that future research focus on the emotional reactions to both internal and artificial feedback. (Author)
