Higher schooling attainment is associated with better cognitive function at older ages, but it remains unclear whether the relationship is causal. We estimate causal effects of schooling on performances on the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) word-recall (memory) test at older ages in China, Ghana, India, Mexico,…

Discusses the concept of metalinguistic awareness and describes the administration of the Test of Metalinguistic Ability (TAM) to 300 Italian elementary school children. (34 references) (CFM)

Examined the relationship between elementary cognitive tasks and the general factor of intelligence ("g") through tests administered to 568 elementary school students in a study of twins. Findings indicate a memory processing component in addition to a general information processing component contributing to "g" estimates. (SLD)

Studies of human information processing have identified two basic ways people process information. Sequential learning solves problems by arranging small amounts of information in consecutive and linear order. Simultaneous processors solve problems by integrating and synthesizing parallel pieces of information at the same time. This study…

Designed to measure children's abilities to synthesize concepts from several sources, this measure is based on the assumptions that children move from the concrete to the abstract, from specific to generic, and that the ability to synthesize and form new concepts is an important prerequisite to reading comprehension. Each form of the test is…

A new model is proposed for explaining children's performance on Pascual-Leone's test of M-space. The new model is used to generate theoretical performance curves for children at four different age levels and seven different levels of stimulus complexity, and it is a viable alternative. Differences between the models are reviewed. (Author/RD)

The purpose of this study was to explore the relationships of certain cognitive variables to problem-solving performance. Cognitive restructuring, spatial ability, reading comprehension, and mathmatical story problems tests presented in a regular verbiage, low verbiage, and drawn formats were given to students in grades three through seven.…

In this article we suggest a method of evaluating learner expertise based on assessment of the content of working memory and the extent to which cognitive load has been reduced by knowledge retrieved from long-term memory. The method was tested in an experiment with an elementary algebra tutor using a yoked control design. In the learner-adapted…

The purpose of this study was to investigate the differences and similarities in the performance of integrated science process skills among learners with differing cognitive-style preferences. In this study, two evaluative instruments were used. The first, the Learning-Style Inventory (LSI) was employed to measure individual cognitive styles.…

The cognitive patterns of 58 "retarded" and 38 below-average readers were compared with controls, according to Luria's simultaneous and successive modes of information processing. Factor Analysis showed different cognitive patterns for disabled and nondisabled readers. Reading skills, rather than cognitive ability, were shown to be…

This study assessed use of five computerized analogy problems as a measure of mental speed with 62 children (ages 3-13) with mild/moderate mental retardation. Results found medium to high correlation between scores on the tasks and other cognitive measures and the adaptive behavior scale. The value of assessing cognitive speed in the cognitive…

This project examined the hypothesis that different background experiences associated with cultural grouping may lead to differences in test-taking strategies which result in score differences extraneous to the abilities the test is intended to measure. Its purposes were to confirm (or disconfirm) the cultural differences hypothesis and to provide…

The differences in performance on a variety of cognitive measures were studied in 67 learning disabled (LD) and normal elementary school children. Younger and older Ss were administered tests of conceptual sorting, central and incidental learning, and selective attention. Teacher ratings of classroom hyperactive behavior were also examined. LD Ss…

Results from correlated multiple-group component analyses of the Revised Illinois Test of Psycholinguistic Abilities (ITPA) subtests were given. Intercorrelations for each age group in the standardization sample provided strong support for the theoretical model underlying the Revised ITPA. (Author/MH)
