This study, involving adults with and without mental retardation and mental age-matched children, employed a lateralized presentation of Stroop color words, neutral words, and the subject's first name. Individuals with mental retardation experienced difficulty in effortful processing (inhibiting the reading response on the Stroop trials) and in…

To assess the sensitivity of Warrington's Recognition Memory Test "words" and "faces" subtests to lateralized temporal lobe seizure foci and effects of epilepsy surgery, 27 left- and 39 right-temporal lobectomy patients were tested before and after surgery. Conditions under which misclassification is most likely are discussed.…

This study of 34 adults with Down's syndrome found that right-handed subjects exhibited no lateral advantage in dihaptic shape-matching, whereas left-handed subjects displayed an expected left-hand advantage. In a visual field dot enumeration task, both groups exhibited left-field superiority. Results indicate that subjects' atypical cerebral…

John Schumann and colleagues have argued for a neurobiological perspective on language acquisition that denies a role for a specifically linguistic mental module of the sort proposed by, for example, N. Chomsky (1986). This report challenges this perspective by offering evidence that such a mental module must be involved in the acquisition of…

Responds to L. Eubank and K. R. Gregg article (this issue), suggesting that they present a narrow view of language that they wish the field of language acquisition to share. It is suggested that Eubank and Gregg contend that the only thing to be explained is the human capacity for grammatical competence. This belief discounts, misrepresents, or…

Twelve males (ages 8-12) with phonological dyslexia were compared to 12 age-matched good readers and 12 reading-matched students. Results showed that dyslexia is not related to incomplete lateralization or to a failure to inhibit verbal processing in the right hemisphere during reading and writing. (Author/JDD)

This article reviews the evidence on the relationship between the two brain hemispheres and creative cognitive processes. It concludes that claims about creativity being "in" one or the other hemispheres represent an uncritical acceptance of naive pseudoscientific beliefs about the brain and brain function. (DB)

Notes that high-resolution magnetic resonance imaging allows in vivo quantification of the surface area of the cortex covering the planum temporale. Reviews the definition of planum asymmetry as it relates to structural accompaniments of disorders such as developmental dyslexia and to anatomic and functional lateralization. Finds support for the…

This article reviews recent evidence supporting a biological basis for developmental dyslexia. It concludes that the combined evidence demonstrating macroscopic morphologic, microscopic neuronal, and microstructural white matter abnormalities in dyslexia is consistent with a localization of the principle pathophysicological process to perisylvian…

Considers how to adapt the design of distance education to students' cognitive styles. Discusses cognitive styles, including field dependence versus independence, holistic-analytic, sensory preference, hemispheric preferences, and Kolb's Learning Style Model; and the characteristics of distance education, including technology. (Contains 92…

This study presented a series of cognitive tasks of increasing difficulty to 27 children (ages 11 to 15) having bilateral, severe to profound hearing loss and a control group. Findings suggest that brain hemispheric interactions may affect cognitive performance in ways predictable from hemispheric-specialization theory and hearing ability.…

Discusses new adult learning theories, including those of Roger Sperry (left brain/right brain), Paul McLean (triune brain), and Howard Gardner (multiple intelligences). Relates adult learning theory to training. (JOW)

Discusses how media educators can improve instruction in the college classroom by being aware of differences in students' learning styles. Addresses two major learning-style elements, hemisphericity and perceptual preferences, and suggests a structure with corresponding methodology for addressing various learning-style needs in a media classroom.…

This study compared hand preference and motor skills in 20 children with autism with 40 children either typically developing or with developmental delays. Results indicated that the lack of hand preference in children with autism was not a function of their cognitive delay or a lack of motor skills. Results supported the bilateral brain…

In this paper, the author concludes that the lesson for music educators is that every musical experience that is offered to students affects their brains, bodies, and feelings. In short, it changes their minds permanently, and, if educators are conscientious, it does so progressively. Such a process is called "learning." That capacity to learn, to…
