The purpose of the present study aims to investigate the relationship between circadian typology and learning-thinking styles conceptualised as a preference toward information processing typical of the right vs. the left cerebral hemisphere. A sample of 1254 undergraduates (380 boys and 874 girls; mean age=21.86+/-2.37,) was administered the…

Prime pictures of emotional scenes appeared in parafoveal vision, followed by probe pictures either congruent or incongruent in affective valence. Participants responded whether the probe was pleasant or unpleasant (or whether it portrayed people or animals). Shorter latencies for congruent than for incongruent prime-probe pairs revealed affective…

In this article, the author describes how researchers study the adolescent brain--a subject of inquiry that did not exist a generation ago. Any parent of a teenager knows that adolescents often have difficulty navigating through their world. Now scientists are starting to find out why. Peering into the minds of maturing youngsters, researchers are…

Samar and Parasnis [Samar, V. J., & Parasnis, I. (2005). Dorsal stream deficits suggest hidden dyslexia among deaf poor readers: correlated evidence from reduced perceptual speed and elevated coherent motion detection thresholds. "Brain and Cognition, 58," 300-311.] reported that correlated measures of coherent motion detection and perceptual…

Neurological examination of children includes the screening for soft neurological signs (NSS). There is little knowledge about their evolution during adolescence, except that their lasting presence has been associated with developmental, psychological, and cognitive disorders. We report the results of a NSS exam (assessing gross and fine motor…

This document discusses the problem of teachers who teach primarily to the left hemisphere of the brain, not allowing the right-brain dominant student to expand his creative ability. It presents information about brain structure and function for educators. A glossary of 25 terms is provided with sources of the definitions. Annotations summarizing…

The study compared the performance of schizophrenic patients and normal controls in their ability to direct visual attention. The first experiment compared 12 adult schizophrenic patients with 30 control volunteers in their ability to orient attention in response to peripheral visual cues. The patients were distinguished from controls by a slower…

A 20-item Piagetian-type sorting task was presented to 12 unilaterally brain-injured adult patients and 12 non-injured controls. The left hemisphere brain-injured subjects and the controls showed preferences for the features of shape and texture. In contrast, the right hemisphere brain-injured subjects preferred the feature of size. (Author)

The exploratory study examined patterns of regional cerebral blood flow in a surface and a deep dyslexic during reading. Significant differences in gray matter blood flow were found between subjects and normal controls. Also differences existed between the surface and deep dyslexic in the distribution of cortical perfusion. (Author/DB)

Examined were electroencephalogram (EEG) asymmetries during the presence of discrete facial signs of emotion among 10-month-old infants who were tested in a standard stranger- and mother-approach paradigm that included a brief separation from mother. Data underscore the usefulness of EEG measures of hemispheric activation in differentiating among…

Investigated digit repetition in unilaterally and bilaterally brain-damaged adults to study the hemispheric and neuropsychological factors that underlie performance. Digit repetition was disproportionately depressed in such patients. The data suggest a differential function hypothesis, as well as a unilateral hemispheric hypothesis that underlies…

This paper reviews three studies which examine cognitive processes and brain electrical activity in gifted children. The studies concentrated on mathematically gifted children and/or their sleep patterns. All three studies used the interhemispheric electroencephalogram to examine the gifted child's ability to harness right hemisphere capacities…

This book presents information to help teachers turn research on brain function into practical classroom activities and lessons, offering: brain facts; information on how the brain processes information; tips on maximizing retention; an information processing model that reflects new terminology regarding the memory systems; new research on how the…

Research is reviewed on the relationship between right hemisphere imagery and the development of creativity. The role of nonverbal imagery in the incubation period is discussed. Note: For related information, see EC 120 232-238. (CL)

The 4MAT System honors the distinctive style that each student brings to the classroom, while helping all students grow by mastering the entire cycle of learning styles. The learner makes meaning by moving through a natural cycle--from feeling to reflecting to thinking and, finally, to acting. Teachers need not label learners by style; instead,…
