A brain laterality test and a creativity test were administered to 119 economics and accounting students and 65 creative arts students. No differences were found between the two types of students in brain dominance or creativity. Students who displayed right hemispheric superiority also excelled on the creativity tests. (JDD)

Explored concepts of brain hemispheric lateralization and distinct right brain functioning in extensive dissociation by administering Dissociative Experiences Scale to 114 engineering students and 92 university drawing students. Chi-square calculation found differences in dissociative scoring levels between groups that approached significance at…

Twenty schizophrenics with flat affect, 19 right-brain-damaged patients, and 21 normal controls were compared on a task of facial emotional expression. Compared to controls, both patient groups were judged as less expressive and displaying more negative than positive emotion. Patients seemed to have difficulty with the expression of positive…

When two masked targets are presented in a rapid sequence, correct identification of the first hinders identification of the second. This attentional blink (AB) is thought to be the result of capacity limitations in visual information processing. Neuropsychological and neuroimaging evidence implicated the right hemisphere as the source of this…

Unilateral forced nostril breathing (UFNB) through the left nostril is associated with enhanced spatial abilities, whereas UFNB through the right nostril is associated with enhanced verbal abilities. However, the effects of UFNB on standard tasks of laterality (e.g., dichotic listening) are unknown. This study employed dichotic listening for word…

To investigate whether concurrent nonverbal sound sequences would affect visual-hemifield lexical processing, lexical-decision performance of 24 strongly right-handed students (12 men, 12 women) was measured in three conditions: baseline, concurrent neutral sound sequence, and concurrent emotional sound sequence. With the neutral sequence,…

The Wada test is at present the method of choice for preoperative assessment of patients who require surgery close to cortical language areas. It is, however, an invasive test with an attached morbidity risk. By now, an alternative to the Wada test is to combine a lexical word generation paradigm with non-invasive imaging techniques. However,…

Two studies examined the effects of handedness on braille learning. Experiment 1 featured 64 sighted undergraduates at North Carolina State University, all of whom were right-handed and had no experience with braille. Results revealed that females outperformed males, but that, contrary to expectation, no significant effects of handedness were…

Individual differences in verbal/analytic and nonverbal/holistic cognitive strategies were studied in relationship to performance levels in spatial tasks, sex and handedness. Analytic processes are described as sequential, resulting in decomposition of stimulus information, and holistic processes, as parallel, involving information synthesis.…

The authors review the history and current status of six areas of inquiry into lateralized cerbral hemispheric functions (cerebral dominance) related to language and learning disabilities. (LC)

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…

Article discussed some educational implications of hemispheric lateralization of the human brain. (Editor/RK)

A study was conducted to provide an assessment of the general efficiency of working memory in relation to level of field articulation. The task required a subject to retain a series of digits for subsequent report while performing a semantic modification of a target phrase. The working memory hypothesis predicts that the joint impact of high…

This paper presents background information, an introductory statement of theoretical positions, and brief abstracts of research papers from a symposium on the functional specialization of cerebral hemispheres in infants and children. According to one view of the development of cerebral specialization, the two hemispheres are initially…
