Describes and critiques a study conducted with boys eight- to fourteen-years-old to test whether intensionality (defined as supraordination) and maladjustment are related. Concludes that the boys tested may have been too young to have fully developed their supraordination abilities and that boys' ability or preference to make supraordinate…

From a review of the literature on modeling processes, observational learning, social learning theory, and vicarious concept learning by young children, the author draws guidelines for the teaching of abstractions to preschoolers. (SJL)

International students in American legal education may need explicit information about our legal culture and its logic. A contrastive approach to studying law can serve all students by putting cultural and disciplinary differences in relief, revealing roots of our own logic and biases. Such an approach requires law faculty to explore other legal…

Children ages 3 to 5 years old are observed in a series of 3 experiments assessing their use of counterfactual thinking in causal reasoning. Results suggest that young children readily interpret the cause of an outcome in terms of a contrast between the observed sequence of events, and a counterfactual alternative in which the outcome did not…

This study examined cognitive ability, short-term verbal memory, and speech perception in relation to phonological awareness in 42 gifted and 49 regular 3rd and 4th graders and in 61 prereading kindergartners. Those with higher cognitive reasoning skills scored higher on tasks of phonological awareness than those with lower reasoning skills.…

Describes a study designed to address the difficulties computer science undergraduates have in learning formal reasoning methods. Computer-based tools providing a mixture of graphical and textual on-screen help were evaluated, and results indicate the tools had a positive effect on the learning process. (Author/LRW)

To enhance the study of abstract knowledge and to make it a central concern in the study of cognition, and to explore the nature of abstractions and the function of abstraction, the seven chapters in this special issue formulate researchable hypotheses, propose working hypotheses, identify major phenomena, and outline possible educational…

This case study uses activity theory to analyze the conceptualization of teaching for an elementary school teacher in her first full-time job teaching a kindergarten/first-grade class. Findings center on teacher's use of integrations and the decentering of the classroom. Rather than sustaining concept of constructivist teaching, the teacher…

Twenty-four gifted children with learning disabilities and a control group of nondisabled gifted children were administered the Wechsler Intelligence Scale for Children-Revised. The 8- to 12-year-old subjects were found to be more reliant on verbal conceptualization and reasoning than controls and demonstrated deficiencies in short-term auditory…

Twenty-four 12- to 19-month-old children were studied to examine the cognitive basis for the emergence of verbs. Substantial increases in verb comprehension across contexts, abstract cognition, and the ability to engage in symbolic action were observed, suggesting a relationship between underlying cognitive development and increased verb…

This study assessed the extent to which procedurally proficient children (N=34) construct the part/whole logical structure that underlies the borrowing algorithm in subtraction. Results indicate that an understanding of the part/whole logic of number may be necessary to understand place value and borrowing. (TJH)

The theorems and proofs presented are designed to enhance student understanding of the theory of infinity as developed by Cantor and others. Three transfinite numbers are defined to express the cardinality of infinite algebraic sets, infinite sets of geometric points and infinite sets of functions. (DC)

Examines successful/unsuccessful distinctions between novices and experts in problem solving in terms of genetic knowledge, use of production rules, strategy selection, use of critical cues, use of logic, understanding of probability, and the thinking process itself. Suggests five implications for genetics instruction and provides three problems…

Four experiments investigated children's ability to notice and remember events in which the acquisition of factual information occurs. Results indicated that children tend to report they have known newly learned information for a long time, suggesting that children have some understanding of knowledge acquisition, but not at the level of adults.…

Examined the nature of perceptual classification in children and young adults. Found that most children attend selectively to one stimulus dimension when making perceptual classification judgments. Suggests that this developmental trend does not appear to be a holistic-to-analytic shift but rather a trend toward greater consistency in following a…
