Abstract
The purpose of this study was to examine whether the Salkind and Wright model for the impulsivity and efficiency dimensions is applicable to younger children as well as to older children in Japanese elementary schools. By using the 144 fourth-graders (mean age, 9 yr. 11 mo.), the efficiency score on the Matching Familiar Figures test rather than the impulsivity score correlated negatively and significantly with both age and most of the performance scores on the Kyoto University NX Group Intelligence test. This result seems consistent with the correlational patterns predicted by the Salkind and Wright model. However, among the 80 first-graders (mean age, 7 yr. 0 mo.) correlations for the same set of variables showed opposite patterns. These results indicate that the Salkind and Wright model can be applied to older Japanese elementary school children but less so to younger Japanese children.
