This study of 38 right-handed children (age range 90 to 201 months) with dyslexia found characteristic patterns of organization of intellectual functions, of hemispheric specialization, and of reading errors in the subtypes, identified as linguistic dyslexia, perceptual dyslexia, and mixed dyslexia.

Among 424 Navajo and Hopi high school students, teachers, parents, and Anglo teachers, all Indian groups differed significantly from national norms in brain dominance or learning style. Mismatches between teaching styles and learning styles occurred between Anglo teachers and all Indian students and between Navajo teachers and students. Contains…

Discusses several technical, psychological, and philosophical reasons for the underestimation of reflective teaching that make use of nonrational teacher behavior. Several techniques are described for the promotion of reflection on nonrational processes, such as the use of metaphors, drawing or painting, making photographs, and guided fantasy.…

Explores research on the concepts of intelligences and giftedness. Considers the importance of the brain, its organization and functions, different theories about intelligence and the possibility of boosting it, and changes that occur in brain structure as a consequence of the interactions between genetic traits and experiences. (Author/CR)

The assessment profiles of 30 school-age children identified with either nonverbal or language-based learning disabilities were examined using a self-organizing systems paradigm. Results suggest that overflow into areas not typically associated with each disability subtype may occur. Concerns regarding ways of determining discrepancy for…

There is much debate as to the extent and nature of functional specialization within the different subregions of the prefrontal cortex. The current study was undertaken to investigate the effect of damage to medial prefrontal cortex subregions in the rat. Rats were trained on two biconditional discrimination tasks, one auditory and one visual, in…

Research on the executive functions of the brain supports a constructivist, experiential approach to teaching and learning.

Despite a century of research, the mechanisms underlying short-term or working memory for serial order remain uncertain. Recent theoretical models have converged on a particular account, based on transient associations between independent item and context representations. In the present article, the authors present an alternative model, according…

Objective: This annotation reviews recent evidence that points to the likely role of aberrant neural oscillations in the pathogenesis of Tourette syndrome (TS). Methods: The available anatomic and electrophysiological findings in TS are reviewed in the context of an emerging picture of the crucial role that neural oscillations play in maintaining…

Background: The aim of this study was to investigate attention orienting triggered by another's gaze direction in autism. Method: Twelve high-functioning children with autism and gender- and age-matched normal control children were studied using two tasks. In the first task, children were asked to detect laterally presented target stimuli preceded…

This study proposes an interactive model of "cross-domain" concept mapping with an emphasis on brain functions, and it further investigates the relationships between academic achievement, creative thinking, and cross-domain concept mapping. Sixty-nine seventh graders participated in this study which employed two 50-minute instructional…

There is a burgeoning interest in the neural basis of the ability to attribute mental states to others; a capacity referred to as "theory of mind" (ToM). We examined the effects of lesions of the amygdala which arise at different stages of development on this key aspect of social cognition. Tests of ToM, executive and general neuropsychological…

With 101 healthy aging adult participants, the authors investigated whether executive functions are a unitary concept. The authors established the factor structure of the Wisconsin Card Sorting Test (WCST; E. A. Berg, 1948), the Stroop color and word test (C. J. Golden, 1978), verbal fluency using the Controlled Oral Word Association Test (COWAT;…

Although lexical decision remains one of the most extensively studied cognitive tasks, very little is known about its relationship to broader linguistic performance such as reading ability. In a correlational study, several aspects of lateralized lexical decision performance were related to vocabulary and reading comprehension measures, as…

The purpose of the present study was to evaluate whether verbal fluency tasks may specifically induce relatively greater left than right hemispheric activation in the dorsolateral prefrontal cortex. The effectiveness of the manipulation was evaluated by EEG, which was recorded during performance of the verbal fluency task and during two control…
