The notion of optimality is often invoked informally in the literature on metacognitive control. We provide a precise formulation of the optimization problem and show that optimal time allocation strategies depend critically on certain characteristics of the learning environment, such as the extent of time pressure, and the nature of the uptake…

In the first of two studies, fifth and eighth graders and undergraduates were shown the patterns of three hypothetical group members' preferences regarding three alternatives. The hypothetical groups members' preferences were ranked first, second, third (Group O); or desirable, neutral, undesirable (Group PN). The subjects' task was to use the…

The inclusion of group activities based on theories of cognitive development within day care settings is urged. Several examples of classroom-tested activities are included. (ED)

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…

ASPECTS OF NEUROLOGICAL RESEARCH ARE PRESENTED UNDER THE TOPICS OF NEUROLOGICAL GROWTH AND DEVELOPMENT, CEREBRAL DOMINANCE, "SPLIT-BRAIN" SYNDROME, AND SEQUENCING. THE FIRST TWO AREAS INDICATE THAT ASSESSMENT OF A CHILD'S NEUROLOGICAL DEVELOPMENT MUST TAKE INTO ACCOUNT VARIATION OF RATE AND DEGREE OF DEVELOPMENT, AND THAT THE SIGNIFICANCE OF…

A testing instrument, the Experimental Phoneme Sequence Test (EPST), was devised to collect baseline information for studying receptive knowledge of phoneme sequencing in normal articulating kindergarten and elementary school children. One hundred kindergarten through fourth-grade children, five male and five female subjects at each half-year…

Deals with memory for lists of items. The literature is briefly reviewed, and the main difficulties for traditional explanations of serial order effects are noted. (RK)

On the basis of these findings, both the measurement techniques of previous studies and Piaget's analysis of seriation are challenged. (Author)

Deficits in position memory particularly seemed to be the major distinguishing variable between normals and retardates in the present study. (Authors)

Using recognition rather than recall test procedures gives results which are inconsistent with the main features of the visual trace model for short-term memory. (Author)

Results suggest that Ss store some of the auditory and visual information in modality-dependent memory systems and that storage order determines recall accuracy. (Author)

Study attempted to specify two complementary aspects of children's inferential size judgments within the context of Piaget's theory. (Authors)

Data suggests that perceptual processing in the language-appropriate direction is an established skill by the time a child finishes second grade. (Author)
