Recent structural and functional imaging work, as well as neuropathology and neuropsychology studies, provide strong empirical support for the involvement of frontal cortex in autism. The Cambridge Neuropsychological Test Automated Battery (CANTAB) is a computer-administered set of neuropsychological tests developed to examine specific components…

The goal of the present study was to examine the contribution of executive function (EF) and social cognition to individual differences in emotion regulation (ER) in preschool children. Sixty 3-, 4-, and 5-year-old children were administered a battery of EF tasks, two theory of mind tasks, a measure of verbal ability, and an ER task. In addition,…

Children's exposure to mind-related talk has been shown to foster young children's metacognitive understanding and to orient them to the patterns of literate language long before they commence formal literacy instruction at school. In this paper, we report on a longitudinal study of the mind-related talk of 22 mothers when their infants were aged…

Working memory (WM) has been associated with the acquisition of arithmetic skills, however, the components of WM that underlie this acquisition have not been explored. This study explored the contribution of two WM systems (the phonological loop and the central executive) to mathematical performance in young children. The results showed that a…

Complex (working memory) span tasks have generally shown larger and more consistent correlations with higher-order cognition than have simple (or short-term memory) span tasks. The relation between verbal complex and simple verbal span tasks to fluid abilities as a function of list-length was examined. The results suggest that the simple…

"Weak central coherence" refers to the detail-focused processing style proposed to characterise autism spectrum disorders (ASD). The original suggestion of a core deficit in central processing resulting in failure to extract global form/meaning, has been challenged in three ways. First, it may represent an outcome of superiority in local…

In S. Kanazawa's (see record 2004-12248-010) evolutionary theory of general intelligence (g), g is presented as a species-typical information-processing mechanism. This conceptualization of g departs radically from the accepted conceptualization of g as a source of individual differences that is manifest in the positive manifold. Kanazawa's theory…

This article presented some of the research on learning processes and illustrated how different modes of thinking can be applied in teaching some topics in secondary mathematics. (Author/RK)

Two processing abilities used to solve spatial problems are examined: (1) the analog ability of structural visualization; and (2) the non-analog ability of verbal analytic reasoning. The distinction is based on an evaluation of information processing theory and a review of process-oriented studies of individual differences. Criteria are presented…

Recent research in persuasion shows that while message recipients often use little cognitive effort when assessing message validity, they may instead rely on a heuristic processing strategy. This study used a priming-like paradigm to manipulate the reliability that subjects apply to the heuristic "message length implies message strength." Subjects…

This final report reviews the main theoretical and empirical developments concerning components of individual differences in human intelligence. The report is divided into three main sections. The first briefly reviews alternative approaches to understanding the nature of intelligence. The second provides the proposed componential metatheory, a…

This analysis of solutions to the Tower of Hanoi Problem underscores the importance of subject-by-subject analysis of "What is learned" in understanding human behavior in problem-solving situations, and provides a technique for describing subjects' task performance programs in detail. (Author/BJG)

Research on aptitude-instructional treatment interactions has shown that the relation of general ability to learning tends to increase as instruction places increased information processing burdens on learners and to decrease as instruction is designed to reduce the information processing demands on learners. This report summarizes a research…

Behaviors that characterize play with convergent and divergent materials and the effects of play on convergent and divergent problem solving were examined in this study. Seventy-two 3- and 4-year-old children were assigned to one of three conditions: (1) play with convergent materials; (2) play with divergent materials; and (3) non-play control.…
