Executing actions in a specific order is a critical component of many action sequences that children must acquire, the majority of which are learned through observation and imitation of others. Although a wealth of evidence indicates that children can process and represent temporal order in memory, relatively little is known about the development…

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…

Looked for evidence of an intermediate stage between the second and third stages in multiple seriation during which subjects seriate the material on one dimension and classify it on the other. Fine grained analysis of stages is considered useful in elucidating the mechanisms of progression through a stage sequence. (GO)

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)
