The optional shift performance of reflective and impulsive girls

Abstract

The optional shift performance of 52 reflective and 50 impulsive second-grade girls was assessed under two response-consequence conditions: (a) reward for correct responses only, and (b) reward for correct responses and a penalty for incorrect responses. Reflection—impulsivity was defined on the basis of performance on the Matching Familiar Figures test. The reflectives showed a significantly greater percentage of reversal shifts than the impulsives. The impulsives showed more reversal shifts under the penalty condition than the reward alone condition whereas the performance of the reflectives was the same in both consequence conditions. A test of statistical association indicated that reflection—impulsivity may be as strongly related to reversal shift performance as age and perceptual pretraining. The results are interpreted as indicating that individual differences in perceptual search strategies may have an important influence on the problem-solving behavior of children.
