Compares the incidence of handedness for specific adult age groups with data collected on children for comparable time spans and makes some judgments regarding incremental tendencies. (Author/RK)

Investigates the relationship between hemisphere, brain preferences, and academic failure or success by studying 131 average and above average fourth and seventh grade students. Concludes that cerebral hemisphere functions do affect learning. (MM)

Reviews research on various physical factors related to learning and reading disabilities, also providing a 58-item bibliography. (VJ)

Questions noted differential effects of left-hemisphere as compared to right-hemisphere brain damage on the Wechsler Vocabulary and Block Design subtests. (MB)

Differences in how the two hemispheres of the brain handle spatial information were studied with blind subjects and blindfolded sighted subjects. The performances of all groups declined as the relative disorientation between the target and its duplicate increased, suggesting that visual imagery is not crucial to mental rotation. (Author/SEW)

Examined the hypothesis that aging and hemispheric laterality interact to produce relatively greater decrements in older individuals in right hemispheric dominant (visuospatial) than left hemispheric dominant (verbal) tasks in 24 early middle-aged and 24 older males. Data did not support the notion of a laterality effect associated with aging.…

A review of studies into the neurological aspects of reading disabilities indicates that two positions have been taken with regard to the brain and reading: (1) language skills are generally considered to be the function of the left hemisphere of the brain; and (2) very poor reading may be related to bilateral spatial processing for both boys and…

This study sought to replicate findings from a clinical sample of boys with two normal day school samples, ages 9-10 and 13-14. Results showed a significant interaction effect only for the older group. (Author/SJL)

Some data on sex and handedness in relation to academic predictors and success in architectural education were reexamined. The new variable was the notion of visual thinking, measured by the manner, "visually" or "cognitively," of executing a simple line drawing. As expected, significant differences appeared between persons using these modes.…

The authors review current brain hemisphere laterality research in relation to music education, concluding that evidence is still insufficient to determine the functions of the left brain and right brain in music perception. They also consider the effects of training on the cerebral processing of music stimuli. (SJL)
