The solution of the relational reasoning task of each subject was measured in terms of reasoning task of four types. The experimental design of this study was 3(age) × 2(working memory level) × 4(types of reasoning task). The collect data was analyzed by ANOVA and simlpe main effect analysis. The results were shown as follow; First, the performance of children's relational reasoning task increased with age.
