Stimulus conditions were found to interact with conservation level and relation type. (MM)

The major objective of this study was to investigate differential performances among 5-year-old children when using transitivity of matching relations. Instruments were constructed to measure the subjects' (1) knowledge of matching relations, (2) ability to conserve the relations, and (3) proficiency in making inferences using the transitive…

A group of 47 kindergarten and first grade children from a school chiefly composed of Negro children from low-income families was involved in this study which followed a Solomon four group design. All children received a pretreatment of 17 lessons on matching relations and length relations. The pretest group was then given six tests on relations,…

This study examined the effects of a specified set of activities on the ability of educable mentally retarded (EMR) children to use the transitive property and conserve the three relations "same number as,""more than," and "fewer than." Thirteen EMR students, aged 12 to 15, were taught eleven lessons on establishing and conserving these relations,…

Two groups of kindergarten children had activities involving the transitive property of matching relations and length relations, respectively. Both groups had activities involving transitivity of weight relations. A control group had instruction only on relations. Pretests of Matching Relations, Length Relations, Matching Relations Conservation,…
