To evaluate the hypothesis that memories are related to operative levels, children were shown pictures involving seriation, horizontality, and verticality and were asked to reproduce them 1 week and 5 months later. Although memories and operative levels did correlate, the relations were quantitatively weak and were undermined by serious…

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)

Investigates the influence of logical skills (inclusion and seriation) on the degree and kind of semantic integration performed on remembered material among 47 third- and fourth-grade boys and girls and college students. (JMB)

This study investigates (1) the relationship of two potentially valuable measures of sequential processing to each other and to a measure of digit span, and (2) the relationships among tests of sequential processing and other measures of cognitive functioning. Subjects were 188 first grade students who had been screened in kindergarten for risk of…

Investigates the role of operative schemes in explaining older children's superior memory on past Piagetian memory tasks. Contrasts were made between the performance of normal v learning disabled grade school children, and between preschool children who either possessed or lacked seriation schemes. (Author/SS)
