To test for interhemispheric difficulties associated with dyslexia, this study assessed bimanual coordination in dyslexic and nondisabled boys using an Etch-a-Sketch-like task. Dyslexics showed significant impairments on mirror movements, and often unknowingly reverted to parallel movements when visual feedback was removed. (RH)

This study explored whether the "right thinking style" relates to creativity as measured by 2 types of creativity tests, which were given to 109 undergraduates. Results correlated the How Do You Think scores positively with right thinking scores on the Your Style of Learning and Thinking test and negatively with left thinking scores.…

A neuroimaging study examined brain activity of normal subjects performing story comprehension tasks necessitating the attribution of mental states. Brain activity was compared with that from two control tasks. Comparison of the "theory of mind" stories with "physical" stories revealed a specific pattern of activation…

A resurgence of interest in the relationship between cerebral lateralization (the functional asymmetry of the cerebral cortex) and aggression has occurred. Most recent studies have found that individuals with abnormal patterns of lateralization are overrepresented among violent individuals. Intervening variables (such as drug and alcohol abuse)…

Brain imaging research allows direct assessment of structural and functional brain abnormalities, and thereby provides an improved methodology for studying neurobiological factors predisposing to violent and aggressive behavior. This paper reviews 20 brain imaging studies using four different types of neuroimaging techniques that were conducted in…

Discusses development of the Sonnier Model of Hemispheric Preference. Notes frequent references to the senses "visual" and "auditory" rather than the two hemispheric functions "visual" and "analytical." (RS)

It is proposed that there is a modular but interconnected system underlying the perceived hierarchical organization of objects. The discussion centers on neural and cognitive mechanisms of organizing objects within objects in at least four separate subsystems. (SLD)

Examines the role of cerebrospinal fluid (CSF), a clear, colorless liquid that constantly bathes the brain and spinal cord. Scientists argue that cerebrospinal fluid carries important signals for sleep, appetite, and sex. Evaluates past and current research documenting the purpose of cerebrospinal fluid in the brain.

Nutrition and learning are inextricably connected. Protein, fat, B vitamins, iron, choline, and antioxidants promote brain functions. The USDA's "Food Guide Pyramid for Young Children" (and adaptations for school-age kids) offers guidelines for formulating a child's diet. Breakfast, family meal-sharing, and exercise are essential.…

Explores the nature of knowledge, particularly the difference between genetic knowledge and cultural knowledge, and its significance for understanding evolution. This exploration is the foundation of a discussion on medical information inherited in genes and accumulated in society. The problems of cultural medical knowledge for evolution are…

Discusses basic facts about the brain and new research findings concerning growth and development that may help reconsider how information literacy skills are taught. Explains Kovalik's Integrated Thematic Instruction Model that recommends taking into account brain research and tying into relevant activities for the entire school year. (LRW)

Discusses the role of movement in brain function for academic learning, examining problems related to children's sedentary lifestyle and highlighting related literature, which includes a study that compared the mental performance of students who were involved in regular continuous activity to that of a group of inactive students and found that…

Describes how to gain optimal learning in the classroom by activating different parts of the brain. Neural systems fatigue very quickly and need to rest. Only a few minutes of factual lecture can be tolerated before the brain seeks other stimuli. The most effective presentation must move back and forth through interrelated neural systems, weaving…

Reviews some of the most pertinent current research on possible causes of dyslexia. Offers guidelines for the prognosis and treatment of dyslexics and literary options for reading teachers and specialists to use in working with dyslexia. (PA)

Investigates differences in brain structures, as reflected in hemispheric laterality, and sex on communicator style preferences. Combines handedness, familial sinistrality, and related correlates as a predictor of standard or anomalous hemispheric dominance. Finds data consistent with hypothesis that communication preferences have a…
