Reviews research on cerebral asymmetry in hearing persons, clinical studies on lateralization and sign language, and experimental research on cerebral asymmetry in deaf persons. (AM)

Reviews research toward defining the neuropathological mechanisms responsible for developmental dysphasia. Hypothesizes that higher level auditory processing dysfunction may result from more basic temporal processing deficits which interfere with resolution of brief duration stimuli. Suggests two alternative hypotheses regarding the…

Cooperative group treatment for aphasia based on cooperative learning principles is designed to improve communication skills during small, two-member group interactions. The treatment involves teamwork incorporating positive interdependence, face-to-face promotive interaction, individual accountability, and group processing. Group size, treatment…

Two claims essential to Kean's interpretation (EJ 165 107) that Broca's aphasia results in a phonological disorder rather than a syntactic or morphological disorder are disputed. The claim that the plural morpheme is derivational, and the postulation of the notion of the phonological word are shown to have no linguistic motivation. (Author/RD)

Reviews research indicating linguistic knowledge is not innate, that the infant brain is highly differentiated at birth, that processing biases that lead to the "standard brain plan" are innate and localized but not specific to language, and that the infant brain is highly plastic, permitting alternative "brain plans." (Author/CR)

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 provides information on aphasia, including the incidence of aphasia; the effects of the disorder; the role of the speech-language pathologist; and the different types of treatment of aphasia. General studies of the efficacy of aphasia treatment are reviewed and a case study is included. (CR)

A discussion of grammatical disorders in aphasia considers an area of ambiguity. In the work of one researcher, impairment of logico-grammatical relations is associated with semantic aphasia, not efferent-motor aphasia. In Western studies, efferent-motor aphasia is associated with impaired comprehension and production of grammar. In order to…

An adaptation of the Fluency in Controlled Association subtest of the Boston Diagnostic Aphasia Examination was administered to language-disordered (N=123) and non-disabled (N=286) kindergarten through ninth-grade students. Lack of significant differences on this task suggests that it may not be an appropriate screening device for identifying…

A study of eight adult chronic aphasic patients' comprehension of sentences and pictures in which comparisons of time and space were crucial was designed to assess A. R. Luria's approach to designing comprehension test tasks. The investigation required patients, with lesions of varying size and location, to determine whether a sentence expressing…

This volume brings to light: (1) studies on the effects of different ways of acquiring and teaching a second language; (2) psychological studies on lexical organization in the bilingual brain; (3) neurological research including more than 100 case studies of polyglot aphasics; and (4) original experimental research on language lateralization in…

This article discusses advances in structural and functional neuroimaging that indicate that, in general, nonfluent aphasias are associated with left pre-rolandic lesions and fluent aphasias occur with left post-rolandic lesions that spare pre-rolandic areas. However, functional neuroimaging studies have also shown that neural dysfunction often…

Investigated the source of agrammatic aphasic patients' difficulty comprehending semantically reversible sentences. Found approximately equal distributions of three distinct patterns. Results conflict with explanations of comprehension failure which state that a single pattern of performance on sentence structures characterizes comprehension of…

In this book, current work and issues in psycholinguistics are reviewed by 19 noted authorities in the fields of psychology, linguistics, education, psychiatry, and medicine. The seven sections of the book discuss past and present issues in psycholinguistics (including controversial issues and the theoretical and historical roots of…

Reviews the research on dementia as it applies to patients suffering from acquired immune deficiency syndrome (AIDS). Describes dementia as involving an acquired persistent impairment of intellectual function with compromises in mental activity, emotions and personality, and cognition. Identifies the unique social, emotional, and legal issues…
