Five-year-old children were trained on the length relationships between adjacent members of a five-term series of sticks, and subsequently tested on their abilities (1) to judge the length relationships between nonadjacent pairs of the series, and (2) to incorporate an unseen novel stick into the series through inference.

Two studies (1) compared the ability of pre- and post-operational children to seriate sets of 4 temporal sequences presented simultaneously and (2) examined the ability to recall sequences when given the initial, middle, or terminal item as a retrieval cue. (SB)

First and second graders (n=81) were randomly partitioned into experimental and control groups. The experimentals were given experiences in sorting and seriating objects. Significant treatment and grade effects (p.01) were found on a seriation test, but no significant relationships between classification and transitivity nor seriation and…

Replicates Inhelder's studies of memory and intelligence, and summarizes the literature which relates directly to the Inhelder studies. (SB)

This study examines the development of children's understanding of temporal cycles and the relationship between cyclic concepts and cognitive development. A sample of 62 children, ranging in age from 4 to 10 years, were administered Piagetian tests of classification and seriation and a variety of specially designed cyclic tasks. (Author/JMB)

Six Piagetian-type tasks, designed to examine associated topological groupings, were examined to determine if a hierarchical relationship existed among them. The groupings examined were: the partitioning of sets and addition of subsets, reciprocity of proximities, one-to-one multiplication of elements, order of placement, symmetrical interval…
