The author explores some of the implications of E. Rossi's hypothesis that "fine literature and poetry is essentially a form by which the words of the left hemisphere give voice to symbols and archetypal patterns of the right" (hemisphere). (Author/PHR)

Discusses the relevance of the study of the neurobiology of cognitive development, for an understanding of both the neural bases and the nature of cognition. Also considered are the age at which hemisphere specialization first appears and whether hemisphere specialization changes over time. (PCB)

Research indicates that deaf individuals do not develop the usual hemispheric specialization for verbal and nonverbal processing and that early severe hearing impairment influences the lateral organization of the brain for interpreting linguistic information. Possible instructional implications include encouraging an early symbol system for…

Apparent ambiguities in Levy and Reid's writing posture criteria and dissimilar criteria used by other investigators are discussed. This review suggests that an adequate test of hypothesized relations among handedness, hand posture during writing, sex, and cerebral organization requires development of a standard set of valid criteria for writing…

This paper reviews literature on the use of dichotic stimulation in individuals with mental retardation, and examines how noninvasive dichotic stimulation relates to hemisphere lateralization. Common findings are discussed concerning direction and magnitude of ear asymmetries, patterns of intrusion errors, and speech lateralization of Down…

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…

Five theories were tested relating to the suspected connection between organic brain dysfunction and poor reading, or dyslexia. Results failed to support the poor lateralization, right hemisphere, global, imbalance theories. Among juvenile offenders, poor reading appears to relate to left-hemisphere dysfunction. (Author)

The author cites experts on the nature of right hemisphere imagery, the vehicle through which incubation (the second component of creativity) produces creativity, and explores conditions under which imagery occurs. A summarization of the incubation process is provided. (PHR)

Theory and research on the relation of lateral dominance to the causation of reading disability are reviewed. Both direct and indirect measures of cerebral hemisphere functioning are considered. (SBH)

Examines findings of scientists and educators who have studied whole brain processes as a means of learning new information and skills. Applies this research to the classroom. (SRT)

Reviews early theoretical and research literature on handedness and places it within the larger context of the nature-nurture controversy. Discussion focuses on Baldwin's study of the development of hand preference in infants in relation to the recapitulation theory, mental development ("dynamogenesis"), and speech development.…

In an effort to establish new means of locating the gifted creative productive thinker, an investigation of current brain research in the areas of hemispheric lateralization, cerebral dominance and conjugate saccadic behavior is analyzed. (Author/PHR)

This article discusses the hypothesis of unilateral left hemisphere damage as an explanatory model for the neurological basis of specific language impairment considering both evidence challenging the theory as well as evidence supporting it. (Author/DB)

In an Internet study unrelated to handedness, 134,317 female and 120,783 male participants answered a graded question as to which hand they preferred for writing. This allowed determination of hand preference patterns across 7 ethnic groups. Sex differences in left-handedness were found in 4 ethnic groups, favoring males, while no significant sex…

To increase teachers' sensitivity to their students' learning styles, this paper points out some behavioral characteristics displayed by many right-hemispheric children. Additionally, the distinction between children who are either "part perceivers" or "whole perceivers" is explained. Functions of brain parts as well as several remedial,…
