Examined consistency of hand preference in a longitudinal study of children between 18 and 42 months of age. Results showed a sex-specific relationship between hand consistence and intellectual development. Females with consistency of handedness were precocious compared to females without such consistency; the same relationship did not hold for…

In assessing reflective gaze preference, students were assigned to right-looking, left-looking, or mixed groups. Those with more clearcut preferences were shown to have superior records of athletic achievement, consistent with the model of functional cerebral space which predicts superior simultaneous task performance for more cerebrally…

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)

Naval recruits attending a remedial reading program were compared to regular recruits on verbal, nonverbal, demographic, and eye-hand laterality measures. Verbal intelligence scores on the General Classification Test differentiated best between the two groups. Findings on race and laterality factors are also discussed. (Author/SJL)

This study measured test-retest reliabilities and interrelationships of four common measures of lateral dominance: dowel balancing, peg placement, grip strength, and conjugate lateral eye movement. Moderate reliabilities for all measures except grip strength were obtained. Subjects' sex may be an important reliability variable. Correlations among…

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)

Presents evidence of differences in brain function lateralization between Japanese-speakers and speakers of Indo-European languages, and suggests that current conceptualizations of brain function specialization are not adequate. (AM)

Twenty-eight L-dyslexic and 26 P-dyslexic children (mean age of 9-10) received hemisphere-specific stimulation (HSS) by presentation of words to right and left fingers, respectively. Relative to controls, HSS-treated L-dyslexic subjects showed larger improvement of accuracy in text reading, whereas HSS-treated P-dyslexic subjects showed more…

Evaluates a substantially updated version of the "classical" idea of a significant relationship in dyslexic children between cerebral lateralization and their word decoding deficits. Finds further evidence that dyslexia is not related to incomplete lateralization. Suggests that dyslexics suffer from exuberant right hemisphere processing in…

A study of 12 patients with left-hemisphere damage (LHD) and aphasia, 10 with right-hemisphere damage (RHD), and 10 controls, sought to identify phonemic and emphatic stress contrasts. Individuals with LHD were unable to identify phonemic stress contrasts with better-than-chance accuracy. Individuals with RHD performed better than those with LHD.…

The present study was conducted to examine hemispheric division of labor in the initial processing and error monitoring in tasks for which hemispheric specialization exists. We used lexical decision as a left hemisphere task and bargraph judgment as a right hemisphere task, and manipulated cognitive load. Participants had to respond to one of two…
