In the neurolinguistic approach to the study of the acquisition of reading and writing, language may be used to express thoughts and intellectual attitudes as well as emotions and emotional attitudes. Experimental studies and clinical data suggest that grammatical rules for spoken language predominantly rely on the left hemisphere of the brain,…

This study presents an empirical investigation of basic processes in the perception of speech sounds. The experimental methods applied have their roots in two different psycholinguistic research paradigms; i.e., "categorical perception" and "dichotic listening." In the categorical perception paradigm, listeners' categorization…

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)…

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…

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…

A lateralized backward masking paradigm was used to examine hemisphere differences in orthographic and phonological processes at an early time course of word recognition. Targets (e.g., bowl) were presented and backward masked by either pseudohomophones of the target word (orthographically and phonologically similar, e.g., BOAL), orthographically…

This study asked whether aphasic adults show different noun/verb retrieval patterns based upon their clinical categorization as fluent or nonfluent. Participants selected either the noun or the verb meaning of target words, as presented in three contexts. The framework was that nouns (associated with temporal lobe function) are processed, stored,…

The present study examined left (LH) and right (RH) hemisphere involvement in discourse processing by testing the ability of each hemisphere to use world knowledge in the form of script contexts for word recognition. Participants made lexical decisions to laterally presented target words preceded by centrally presented script primes (four…

Sex differences on language and visuospatial tasks are of great interest, with differences in hemispheric laterality hypothesized to exist between males and females. Some functional imaging studies examining sex differences have shown that males are more left lateralized on language tasks and females are more right lateralized on visuospatial…

Little is known in cognitive neuroscience about the brain mechanisms and brain representations involved in bilingual language processing. On the basis of previous studies on switching and bilingualism, it has been proposed that executive functions are engaged in the control and regulation of the languages in use. Here, we review the existing…

Spoken language comprehension requires the coordination of different subprocesses in time. After the initial acoustic analysis the system has to extract segmental information such as phonemes, syntactic elements and lexical-semantic elements as well as suprasegmental information such as accentuation and intonational phrases, i.e., prosody.…

Explanations for left hemisphere language laterality have often focused on hemispheric structural asymmetry of the planum temporale. We examined the association between an index of language laterality and brain morphology in 99 normal adults whose degree of laterality was established using a functional MRI single-word comprehension task. The index…

Recent neuroimaging studies and neuropsychological data suggest that there are regions in posterior auditory cortex that participate both in speech perception and speech production. An outstanding question is whether the same neural regions support both perception and production or whether there exist discrete cortical fields subserving these…

An event-related brain potential experiment was carried out to investigate on-line syntactic processing in patients with Broca's aphasia. Subjects were visually presented with sentences that were either syntactically correct or contained violations of word-category. Three groups of subjects were tested: Broca patients (N=11), non-aphasic patients…

This study examines well-compensated adults with dyslexia to see if they experience more problems with pragmatic awareness than the normal population. Social interaction requires an individual to process language at speed by using working memory efficiently, in order to understand the intended, rather than literal, meaning between speaker and…
