Research into mathematical processes and their development is first viewed from the perspective of previous research that was directed towards the reading process. It is felt that the study of mathematics affords the experimental psychologist a well-specified domain of information with which to examine the full range of cognitive processes.…

Several writers have suggested that changes in temporal perspective during adolescence are largely a consequence of the cognitive acquisitions held to characterize the period (i.e., emergence of formal operations reasoning). To replicate earlier research, which found little association between adolescents' formal operations reasoning and future…

Children, 24-36 months old, were studied in an effort to examine the influence of cognitive development on the nature of information extracted from stimuli and coded into memory. (ST)

In this study, two cognitive-psychomotor tasks (dry mounting and laminating) were programed and a hardware delivery system, featuring an auto-program stop and slide synchronization capability, was developed and tested. (Author)

This study attempted to determine the functional components of rehearsal strategies in children's discrimination learning. When a discrimination list was given without rehearsal instructions, ability to discriminate situational frequencies predicted performance. Without rehearsal strategy, subjects' ability to discriminate between previous usage…

Discusses how one's conception of intelligence and its development profoundly affects the formulation of educational objectives. A mechanistic conception of intelligence leads to the definition of objectives as a collection of fragmented "cognitive skills", while a Piagetian conception attempts to develop children's intelligence as an…

Forty-eight kindergarten children were divided into four groups on the basis of their status (preoperational vs. transitional) and whether or not they received inversion-negation training. Results indicated no differences due to status, but differences due to training. Results do not confirm the contention that acceleration can only occur during…

This article provides a comparative analysis of studies in which symbolic play in children ages 1 through 3 was the major focus of a formal research strategy. The review provides readers with (1) information allowing more effective evaluation of research involving symbolic play and (2) background for designing or adopting play measurement…

Performance differences between male and female students in proportional reasoning tasks were analyzed with respect to task characteristics. The student performance was also compared to their visual-spatial ability to determine whether such ability correlates with a better performance. The task characteristics tested were ratio complexity,…

The role of visual-spatial operations in nonroutine mathematical problem solving in schoolchildren is investigated through a search of related literature. It is suggested that certain visual-spatial operations are concomitant with the mental processes necessary in problem solving. The following topics are discussed: (1) the importance of problem…

This research explored the development of reasoning about persuasion. First-grade, seventh-grade, and undergraduate subjects were individually presented with a hypothetical persuasive situation in which a young child attempts to obtain a toy from various "targets." Pairs of tape-recorded persuasive appeals were randomly presented to each…

THE PURPOSE OF THE STUDY WAS TO EXPLORE THE PIAGET CONCEPT OF CONSERVATION WITH REGARD TO THE CHILD'S CONCEPT OF THE PROPERTY OF LIQUIDS. AN INVESTIGATOR-CONSTRUCTED CONSERVATION INVENTORY WAS GIVEN TO 45 KINDERGARTEN AND FIRST GRADE PUPILS SELECTED FROM THE PRAIRIE ELEMENTARY SCHOOLS, URBANA, ILLINOIS, TO PROVIDE AN INDEX OF THE CHILD'S…
