This paper estimates the effects of handedness on earnings. Augmenting a conventional earnings equation with an indicator of left-handedness shows there is a positive effect on male earnings with manual workers enjoying a slightly larger premium. These results are inconsistent with the view that left-handers in general are handicapped either…

Objective: Executive dysfunction in ADHD is well supported. However, recent studies suggest that more fundamental impairments may be contributing. We assessed brain function in adults with ADHD during simple and complex forms of processing. Method: We used functional magnetic resonance imaging with forward and backward digit spans to investigate…

In this review, we report on studies that have assessed the effects of exogenous and endogenous increases in stress hormones on human cognitive performance. We first describe the history of the studies on the effects of using exogenous stress hormones such as glucocorticoids as anti-inflammatory medications on human cognition and mental health.…

Dance is a common metaphor in both the change and leadership literature. However, can dance, a movement art, actually be used to learn about leadership? The answer is yes and this exercise shows you how. Dance as an instructional strategy allows the instructor to tap the cognitive, affective, and conative components of the brain.

Briefly reviews theories of brain hemisphere functions and draws implications for social studies instruction. Maintains that the metaphor aids the development of understanding because it connects right and left brain functions. Provides a learning activity based on the metaphor of the U.S. government functioning as a machine. (BSR)

The article reviews the literature on creativity, learning styles, brain studies, teaching technologies, and learning strategies. Although learning styles and strategies differ among individuals, creativity is maximized through use of the fully functioning brain. Teaching suggestions include producing alternative explanations/consequences,…

This study investigates the relationships between undergraduate hypermedia users' information processing styles and navigational patterns. Discusses use of the Human Information Processing Survey, learning styles and information processing styles, and brain hemisphericity. Results show a significant relationship between information processing…

It has been suggested that neglect patients misrepresent the metric spatial relations along the horizontal axis (anisometry). The ''fabric'' of their internal spatial medium would be distorted in such a way that physically equal distances appear relatively shorter on the contralesional side (canonical anisometry). The case of GL, a 76-year-old…

The existence of a rostrocaudal gradient of medial temporal lobe (MTL) activation during memory encoding has historically received support from positron emission tomography studies, but less so from functional MRI (FMRI) studies. More recently, FMRI studies have demonstrated that characteristics of the stimuli can affect the location of activation…

Recent research in cognitive neuroscience has yielded a more comprehensive understanding of brain function. Some of these diagnostic techniques include the event-related potential, which depicts brain electrical activity, and magnetic resonance imaging and positron emission tomography, which are particularly sensitive to the delineation of brain…

The National Council of Teachers of Mathematics (NCTM) poses constructivist ideas in its "Principles and Standards for School Mathematics" (2000). NCTM supports mathematics instruction that takes a developmental perspective; starts and builds on what children know; and leads children to construct relational understanding, problem-solving…

There is a need for artists and for art educators to know about current research into different ways of thinking pertinent to both the creation and perception of art. Brain hemispheric research has stimulated new ideas about teaching processes that nurture spatial thinking and bring a positive new force to the studio and classroom. An introduction…

Examines findings of scientists and educators who have studied whole brain processes as a means of learning new information and skills. Applies this research to the classroom. (SRT)

This article reviews the work on patients who have undergone partial or complete brain bisection and addresses the concept of modularity from three different perspectives: (1) structure-function correlations; (2) modular components of cognitive processes; and (3) integration of modular processes. Several brain pictures and diagrams are presented.…

Examines hemispheric differences in cortical arousal as a function of positive and negative emotional television scenes. Finds that (1) the processing of emotional content is hemispherically asymmetric; and (2) negative material produced greater cortical arousal in the right hemisphere and positive material greater arousal in the left.
