The purpose of the present research was to investigate developmental trends in children's class-inclusion performance and to examine the influence of task characteristics(provision or deprivation of quantitative information and perceptual information) on a class-inclusion task. The subjects of this study were 96 children, 12boys and 12girls at each age level. 5, 6. 7 and 8 years of age. The experimental materials consisted of 12 stimulus boards which were constructed on the basis of picture cards used by Judd and Mervis(1979) and Lane and Hodkin(1985). The class-inclusion tasks were individually administered by the researcher. The data were analyzed by the statistical methods of t-test, one-way ANOVA and Duncan multiple range test. The results showed that (1) There were significant age differences in children's class-inclusion performance. That is, children's performance scores on the class-inclusion task increased with age.: (2) There were significant task characteristics differences in children's class-inclusion performance. That is, children performed better on the deprivation of quantitative information task than on the provision of quantitative information task.
