Time production is an experimental paradigm that compares the accuracy with which a subject can produce a specified time interval relative to actual clock time. Higgins (1987) found that subjects perceived the passage of time as faster or slower, compared to actual time, as an interrelation of personality characteristics and experimental…

Individual differences in performance on figural analogy tests are usually attributed to quantitative differences in processing parameters rather than to qualitative differences in the formation and use of representations. Yet aptitude-related differences in categorizing standardized figural analogy problems between high and low scorers have been…

This project was designed to construct a single theoretical framework for the analysis of problem solving and real time "attention and performance" behavior. The model was developed as a computer program. It was designed in a similar manner to that of various problem solving simulations that use the "production system"…

Research on the nature of gifted children's learning is reviewed. Studies are cited on the following topics: cognitive style (learning style preferences, field independence/dependence, locus of control, and hemispheric specialization), cognitive development (differentiated stage development), cognitive strategy selection (components of problem…

Although it is commonly assumed that increases in mathematical knowledge and problem-solving skill alter one's understanding of mathematical problems, little research exists to support this assumption. The present study investigated the relationship between mathematical background and problem perception in two experiments. Experiment 1 employed…

This study was designed to determine the relationship between children's reflection-impulsivity and responses to a forced choice of a toy for play (labelled as impulsivity) and the length of continued play with the selected toy (labelled as latency). A group of twenty four-year-olds, male and female, were observed making a choice between toys. The…

This study focuses on the mental processes used during estimation. This research: (1) developed an operational definition of estimation; (2) created an instrument to identify exceptionally good estimators; (3) collected performance level data on 1187 subjects; (4) constructed interview problems and developed protocols to identify the thinking…

Reports results obtained when 24 14-year-old students were presented with algebra tasks by a computer-based modeling system and, four months later, comparable paper and pencil tests together with detailed interviews. Comparison of the results revealed profound misunderstandings of algebraic notation and identified classes of strategies used by…

Measures of six cognitive styles, six abilities, and 12 aptitudes were administered to 20l Navy recruits. Relationships among all cognitive attributes and between sets of styles and aptitudes were examined. Results indicated that many styles are significantly related to abilities and aptitudes.

Tested the hypothesis that increasing problem complexity elicits strategies of greater efficiency from older adults. Responses of older and younger adults were compared in a version of "Twenty Questions." No evidence was found that older adults seek more efficient strategies. Both groups maintained the same strategies. (Author/JAC)

Examined the effect of stimulus content on logical performance in a reasoning task. Earlier reports of the facilitating effect of thematic material on the tendency to reason logically were not supported, nor were previous reports that matching is the most common determinant of behavior. (Author)

Discusses the concept of cognitive style and its usefulness as a means of analyzing problem-solving or decision-making behavior. Cognitive style dimensions and models useful for analyzing information/library science professionals are described, and the implications of this research for professional training are discussed. There are 13 references.…

The aims of this study were (1) to test the dyadic superiority hypothesis by comparing dyadic performance on a logical reasoning task with the performance of children working alone, and (2) to determine whether the incorrect child's compliance with the correct child was a major factor in the dyadic production of correct answers.

The article examines the reflective versus the impulsive cognitive styles and the implications of these styles for special education teachers. (PHR)
