Examines the language processing and acquisition abilities of the right hemisphere. Discusses functions performed by the right hemisphere that could play an important role in second language acquisition. (EKN)

Fourteen native speakers of German heard normal sentences, sentences which were either lacking dynamic pitch variation (flattened speech), or comprised of intonation contour exclusively (degraded speech). Participants were to listen carefully to the sentences and to perform a rehearsal task. Passive listening to flattened speech compared to normal…

Research on brain hemisphere functions appears to indicate that (1) lateralization occurs from about age five to puberty; (2) both hemispheres are involved in language learning in ways not yet fully understood; (3) after age fifteen, pronunciation learning becomes difficult; (4) older language learners learn more quickly, but younger learners…

One of a series of semiannual reports, this paper presents articles exploring the status and progress of studies on the nature of speech, instrumentation for its investigation, and practical research applications. Titles of the papers and their authors are as follows: (1) "Lexical Organization and Welsh Consonant Mutations" (S. Boyce, C. P.…

Two experiments tested the limiting case of a multiple resources approach to resource allocation in information processing. Results contradict a single-capacity model, supporting the idea that the hemispheres' resource supplies are independent and have implications for both cerebral specialization and divided attention issues.

Explores the neural and hormonal basis of human intellectual function that gives rise to sex differences in the brain. Discusses behavioral, neurological, endocrinological studies, and studies of the effects of hormones on brain functioning that show a relationship between cognitive variations and sex. (MCO)

This article summarizes work in progress at the Bowman Gray School of Medicine (North Carolina) on the structure and physiological profiles of reading disability and relates the findings to core left-hemisphere language functions. Data add evidence of the structural anomalies associated with dyslexia and evidence of its heritability, especially of…

A study investigated patterns of neurological event-related potentials (ERPs) elicited by morphosyntactic violations in 16 right-handed, English-speaking subjects. Manipulation of stimulus grammaticality and block probability led to ERP effects consistent with those in previous research on syntactic and semantic processing. Results also provide…

Recently, knowledge of the mechanisms of visual-spatial attention has improved due to studies employing single cell recording with alert monkeys and studies using performance analysis of neurological patients. These studies suggest that a complex neural network including parts of the posterior parietal lobe and midbrain are involved in covert…

Three aspects of language behavior--linguistic independence, linguistic interference, and code-switching, are an integral part of the language processing experiences of the bilingual person. Complex cerebral mechanisms function in a coordinated effort to analyze and synthesize the various components of linguistic codes, store them in semantic…

Two studies evaluated the interhemispheric transmission deficit explanation of reading disability by comparing second- and sixth-grade normal and poor readers on learning and discrimination tasks involving hemispheric presentations of visual stimuli. Results suggested verbal processing rather than interhemispheric transmission as a cause of group…

A weakness in accessing the sounds of spoken language represents the most robust and specific correlate of reading disability in young school age children and adolescents. Neurological science and reading research that provides the scientific knowledge regarding this disability is presented.

According to recent neurolinguistic theories and research, language and other analytic functions are located on the left side of the brain, while spatial and configurational abilities are located on the right side. However, there is some evidence that while learning a language requires the use of both hemispheres of the brain, the right hemisphere…

Various communication studies have revealed the existence of a "preverbal" stage of communication consisting of centers within the brain that exists in an innate form or a form preprogrammed for future information acquired from the environment through experience (socialization). Such centers serve to prepare the individual for…

Studies in psychology, language, and foreign language suggest that it is the qualitative nature of the task students perform while learning that is important, because of the creativity factor. Some explanations of creativity are concerned with hemisphericity of the brain. Another explanation is that creativity results from divergent rather than…
