Article investigated a more precise characterization of dominance with the focus on recent research on the brain's left hemisphere. (Author/RK)

Discusses a controlled experiment in which right and left hemisphere activity determines selected emotional responses to visual stimuli. Findings suggest that each hemisphere has a distinct emotional response. Both hemispheres contribute to the individual's perception of the world. (EB)

Two experiments investigated whether poor readers eventually establish a dichotic right ear advantage as predicted by a maturational lag theory. The first studied developmental differences in dichotic listening for normal and poor readers when the order of reporting simultaneously presented items was unconstrained; the second controlled for order…

Neurologist Richard M. Restak discusses empirical research that demonstrates significant brain-sex differences between males and females. He asserts that the typical primary classroom is geared to skills that come naturally to girls but develop slowly in boys, while the reverse is true in higher level science classes. (Author/WD)

Research conducted by Tadanobu Tsunoda on auditory and visual sensation, designed to test and understand the functions of the cerebral hemispheres, is discussed. Tsunoda discovered that the Japanese responses to sounds by the left and the right sides of the brain are very different from the responses obtained from people from other countries. His…

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…

Discusses a study of the neurophysiological effects of television viewing and their impact on learning. Study of brain waves while viewing indicates that the brain switches off from any analytical processing of the messages. (JMF)

The magnitude of the dichotic right-ear advantage was assessed in 48 normal and 48 learning-disabled children representing an age range of approximately five years. (MP)

Describes the characteristics associated with the left and right hemispheres of the brain and relates the rise of phonetic literacy and logic to left hemisphere dominance and the viewing of television to right hemisphere dominance. (JMF)

A study involved the development and testing of a theoretical framework of cerebral specialization in which each hemisphere of the brain is viewed as an independent information processing system. During the study, four sets of experiments were conducted. These involved behavioral as well as electrophysiological measures. According to the…

The effects of laterality, movement, and language on children's ability to conserve multiple space relations were investigated in this study of visuo-spatial dimensionality acquisition. The sample for the experiment consisted of 160 first-graders (80 boys, 80 girls) who were matched on intelligence and socioeconomic status. These subjects were…

Image making, like writing and speaking, is a carrier of ideas. This paper presents photography as therapy, a useful concept for advocates of humanistic education. The paper shows that Western civilization, due to its preoccupation with science, technology, and commerce, enhances and promotes left-hemispheric brain functions (verbal, analytical,…

Two visual search experiments suggest that: cerebral lateralization of cognitive functions results from differences in sensorimotor resolution capacities of the hemispheres; both hemispheres can process verbal and visuospatial information analytically and holistically; and respective hemispheric competence is a function of the level of…

Using a sample of 77 10th grade boys, the researchers studied the relationships between the mental abilities measured by the Differential Aptitude Tests and cerebral dominance (CD: the extent to which one hemisphere of the brain dominates the other for control of behavior). The surprise finding was that CD was negatively related to spatial…
