Presents an investigation of the hypothesis that an increase in the salience of the total class dimension should improve class-inclusion performance. Subjects were 220 children in kindergarten through third grades. (SDH)

Employed regression analysis to determine the association between multiplicative classification and inductive reasoning. Subjects were 103 fourth grade children. (SDH)

One finding is that the children in this study did not reach a level in the development of these concepts expected by Piaget of 9-year-olds. (Authors/CB)

Two experiments examined the effects of blocking of word lists (grouped by semantic category membership or randomly ordered) on the dichotic listening performance of second-and fifth-grade children. (CM)

A group of perceptual and motor tests were administered to 155 advantaged and disadvantaged student. The results are discussed in terms of differential perceptual-motor and motor growth and need to structure educational experience that will contribute to growth. (Author)

Piaget, in describing the sequence of classificatory development, describes class inclusion as composed of two processes; hierarchical classification and post-whole comparisons. In the experiment reported here, elementary school children, trained in the concept of sets in first grade mathematics were given a task where they were required to assess…

The relationship between performance on various Piagetian and reading achievement tasks as examined through 26 correlational studies is reviewed. The following areas of concern are addressed: (1) sample characteristics of the subjects; (2) classification of the Piagetian tasks into five categories of logical operations, spatial concepts, general…
