Two findings serve as the hallmark for hemispheric specialization during lateralized lexical decision. First is an overall word advantage, with words being recognized more quickly and accurately than non-words (the effect being stronger in response latency). Second, a right visual field advantage is observed for words, with little or no…

Reports describing subcortical apraxia of speech (AOS) have received little consideration in the development of recent speech processing models because the speech characteristics of patients with this diagnosis have not been described precisely. We describe a case of AOS with aphasia secondary to basal ganglia hemorrhage. Speech-language symptoms…

Differences between left and right hemispheric subjects in recalling information presented as pictures and words were studied. The hemisphericity of 133 college students (37 males and 96 females) was identified using the Human Information Process Survey. These subjects were shown 25 concrete nouns individually either as pictures or words. The data…

There is a growing awareness among researchers that the magnitude of cognitive sex differences is affected by a number of subject variables. To examine spatial and verbal cognitive sex differences as a function of personal and family handedness, the 478 offspring who participated in the Minnesota family study and 454 offspring who participated in…

This review of the literature on the workings of the brain in relation to learning and instructional design reviews recent research on both long- and short-term memory, and discusses findings on lateralized or "split-brain" functions. Problems associated with short-term memory are also considered, and the concept of the Tribune Brain is…

Whether intuitive abilities can be improved through purposeful training for a more holistic approach to education was the object of this study. It was hypothesized that individuals participating in a mental training program designed to improve right-brain intuitive abilities would show significant improvement in such abilities, while a control…

The study examined the relationship between perinatal stress and decreased right handedness and decreased left cerebral dominance for speech with 215 children born prematurely, followed from birth, and tested at age 5. Results indicated that neither hand preference nor hand performance correlated with degree of perinatal stress and that eye…

Recent research has confirmed that hemispheric patterns of dominance are related to reading skills. Reading is more complex than speech because it includes a visuo-spatial element. In the great majority of people, the left hemisphere deals with speech and sequencing skills. Visual matching of printed words requires the spatial skills of the right…

This paper reviews research and opinions concerned with the lateralization of brain functions and cognitive development as described by Piaget. Optimal cognitive functioning in humans is a product of the complete development of interhemispheric communication in the brain. Growth spurts in brain development have been found to correlate closely with…

This abstract bibliography cites recent ERIC documents and journal articles concerning the differentiated functioning of the brain hemispheres. Entries include resumes from Resources in Education (RIE), October 1973 through December 1977, and citations from Current Index to Journals in Education (CIJE), November 1974 through December 1977.…

A SELECTED READING AND REFERENCE LIST OF PUBLICATIONS FROM 1896 TO 1966 ON THE NATURE, RECOGNITION, AND TREATMENT OF LANGUAGE DIFFICULTIES IS PRESENTED. THE TITLES WERE SELECTED ON THE BASIS OF RELEVANCE TO THE GENERAL INTERESTS AND SPECIFIC NEEDS OF PEOPLE CONCERNED WITH LANGUAGE DISORDERS, PARTICULARLY WITH A SPECIFIC LANGUAGE DISABILITY.…

This longitudinal study was a replication of two disparate studies, one of dominance and one of control, which had as subjects 277 seventh- and eighth-grade pupils remaining from an original dominance study of over 500. Eye dominance was determined through hole-in-paper and V-scope; eye control at near and far point, through the telebinocular;…

This study investigates the hypothesis that it is mixed-dominance among left handers (i.e. left handedness and right eye and/or foot dominance), that is related to academic learning difficulties among such individuals, rather than the generally held notion that their difficulties stem from the fact that they are left handers in a "right…

Two experiments involving listening preferences of autistic and normal Ss were conducted to test the hypothesis that the right cerebral hemisphere is more active than the left in autistic children. (Author/BD)
