Discusses the most significant findings of recent research and scholarship on the nature of the brain and its relevance to the teaching and learning of human languages. Topics covered include: (1) whether the brain is highly integrated or componential; (2) differences between conscious and unconscious processes; (3) hemispheric specialization; (4)…

This review of the literature on laterality research concludes that, despite advances in the classification accuracy of laterality methods, definitive conclusions about hemispheric specialization in individual cases of dyslexic children cannot be drawn. Event-related measurements of cerebral metabolism promise to complement but not replace…

Brain electrical activity (electroencephalogram; EEG) was recorded in a sample of low-income, black, and Hispanic mothers with and without depression and their three- to six-month-old infants. A greater number of mothers with depression and their infants versus mothers without depression and their infants displayed right frontal EEG asymmetry.…

Examined cerebral activation during sign language comprehension in six persons with deafness and nine hearing persons, all of whose parents were deaf. The group with deafness showed more activation than the hearing group in the right parieto-occipital region, indicating that they were more dependent on the spatial components in sign language than…

This article describes the language development in a left-handed young child with a left middle cerebral artery infarction. Patterns of development observed between 36 and 60 months of age are described as a transient jargon or fluent aphasia possibly resulting from initial reliance on an uninjured right hemisphere.

The construct validity of Boder's typology of dyslexia was investigated using quantified electroencephalography with 39 children (ages 7-11) during a reading task and at rest. Results supported beta frequency differences in anticipated regions by dyslexia subtype during the reading task. However, the direction of difference hypothesis was not…

A Southern College of Optometry (Tennessee) study found the largest proportions of students to have converger or assimilator learning styles; more women than men were divergers. Substantial differences in men and women were found in hemispheric preference. Results suggest students with differing learning styles will perform differentially in…

An exploration of a popular model of bilingualism and bilingual behavior, based on Ervin and Osgood's (1954) survey of psycholinguistic theory and research, discusses misinterpretations, limits, and risks; natural and simulated bilingualism and complementary distribution of domains; and subordination and interference, compounding and fusion, and…

Kolb's Experiential Learning Model suggests that people differ in how they perceive and process information. Public agency training should incorporate knowledge of brain hemisphere dominance and learning style preferences in training design. (SK)

Discrimination and phonetic identification abilities of children (ages 5-6) with language impairments were compared to those of normally developing 4-year-olds and previous findings on children and adults. Results support hypotheses suggesting disorders in the phonological component of working memory in children with language impairments and the…

Contrary to dogma, the human brain does produce new nerve cells in adulthood. The mature human brain spawns neurons routinely in the hippocampus, an area important to memory and learning. This research can make it possible to ease any number of disorders involving neurological damage and death. (CCM)

Provides a general review and discussion of studies relating to hemispheric asymmetry in normal and reading disabled populations and possible implications with regard to the meaningfulness of IQ test results. Emphasizes research suggesting that the verbal factors of the WISC-III are related to the length of the left temporal bank of the planum…

Converging evidence from a number of neuroimaging studies suggest that fluent word identification in reading is related to the functional integrity of two left hemisphere posterior systems: a temporo-parietal system and a ventral occipito-temporal system. Readers with difficulties demonstrate heightened reliance on both inferior frontal and right…

This study examined the co-occurrence of both verbal and nonverbal deficits in adults with developmental language disorder (DLD). Comparison with adults without DLD revealed replicable differences between groups on both verbal and nonverbal tasks. Also, an association was found between performance on tests sensitive to facial affect and spatial…

Ingenious and seemingly powerful technologies have been developed recently that enable the visualization in some detail of events in the brain concomitant upon the ongoing behavioral performance of a human participant. Measurement of such brain events offers at the very least a new set of dependent variables in relation to which the independent…
