Children completed three types of equivalent cardination tasks which assessed the influence of different stimulus configurations (linear, linear-nonlinear, and nonlinear), and density of object spacing. Prior results reported by Siegel, Brainerd, and Gelman and Gallistel were not replicated. Implications for understanding cardination concept…

Presents the results of a study in which students undertaking postgraduate (PhD) research were given a small battery of psychological tests, the scores from which were then related to ratings provided by academic tutors. The results are discussed and some explanations are suggested. A 31-item reference list is included. (Author/JL)

Two statistical indices of distinctness (intensity) were developed to measure patterns of cognitive preference scores. Results indicated a variety of cognitive preferences, and the distinctness variable was shown to be a useful tool in cognitive preference research. (CJ)

Kindergarteners asked to predict which of 18 unrelated pictures they would be able to recall were shown to be as discriminating as older children at predicting memorability in a signal-detection analysis. Justifications for why items were memorable showed increased reference to item and task characteristics with increased age. (Author/CM)

Developmental differences in reasoning ability and item processing demands are analyzed in a study of cognitive determinants of number analogy performance in two IQ levels of elementary school children and college students. The amount of solution-related information in working memory was the crucial processing demand. Process differentiations of…

This training study examined the modifiability of older adults' (n=73) performance on measures of attentional processes and training transfer to the psychometric ability domains of perceptual speed, memory span, and fluid-crystallized intelligence. Significant training effects occurred for attention measures, and these effects were maintained at…

Defined competence as effectiveness in dealing with one's environment and assessed (N=27) independently living older adults. Results found higher levels of competence were associated with a more demanding environment, and engaging in more activities. Cognitive test performance was related to both competence and quality of lingiustic tasks. (JAC)

Studies a test based on coded data from spontaneous behavior of children (two-seven years) presented with the Lock Box. Scales were derived measuring psychomotor competence, organization of exploration, and aimlessness. The test was administered to normal and retarded children, with the retarded's responses significantly poorer on all scales.…

Employed two strategies used to test prerequisite relationships among intellectual skills to examine the sequence of three types of subtraction tasks. A psychometric validation strategy yielded results similar to instructional validation strategy. Supports the use of the more efficient psychometric approach for validating large numbers of learning…

Three experiments involved imagining the result of either an array rotating relative to a fixed viewer or a viewer rotating relative to a fixed array. The data suggested that adults use literal, concrete strategies to solve these problems. (Author/PN)

Determined developmental level to be a major factor at lower level chemistry courses but not as important for higher level ones. Suggests Lawson's test to be a useful tool in studying the basics of chemical education, evaluating courses as to the appropriate level, and in counseling individual students. (Author/JN)

Describes two studies of which one analyzes syntactic complexity in writing samples by secondary and postsecondary students, while the other correlates the syntactic dimensions revealed by the former with measures of cognitive style. Correlations indicate an association between complexity and analytic cognitive style. (MES)

This study examined relationships between measures of personality characteristics, personal and teaching practices beliefs, levels of dogmatism, and cognitive outcomes for a sample of graduating education students. (Author/GSK)

Raven's Progressive Matrices test items were analyzed for M demand (Pascual-Leone's developmental construct). Data on second- and third-grade subjects were analyzed for extent of absolute agreement of Raven and Figural Intersection Test (FIT) scores. Raw scores on the Raven could be deduced on the basis of FIT performance. (Author/RD)
