This book examines research on creative thinking, both current and historical. It explores two dimensions of human thought (time and space) and two modes of thinking (conscious and unconscious) as well as both left and right brain functions and artistic and scientific creative activities. The book proposes a "Double Circulation" model of…

Executive function (EF) skills are the attention-regulation skills that make it possible to sustain attention, keep goals and information in mind, refrain from responding immediately, resist distraction, tolerate frustration, consider the consequences of different behaviors, reflect on past experiences, and plan for the future. As EF research…

Effects of advanced aging on hemispheric organization for linguistic processing was investigated with 24 geriatric subjects. Findings indicated that only the left hemisphere was used in language processing, suggesting that right hemispheric language processing ability is inhibited in the elderly. (Author/DB)

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…

The study assessed how unilateral right hemisphere brain damage (RHD) affects processing of metaphoric aspects of word meaning. RHD stroke patients (N=25) performed similarly to left-brain-damaged and normal subjects in the automatic condition and when provided with processing strategies. Both brain-damaged groups had difficulty developing…

This study, involving adults with and without mental retardation and mental age-matched children, employed a lateralized presentation of Stroop color words, neutral words, and the subject's first name. Individuals with mental retardation experienced difficulty in effortful processing (inhibiting the reading response on the Stroop trials) and in…

This study presented a series of cognitive tasks of increasing difficulty to 27 children (ages 11 to 15) having bilateral, severe to profound hearing loss and a control group. Findings suggest that brain hemispheric interactions may affect cognitive performance in ways predictable from hemispheric-specialization theory and hearing ability.…

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.…

Reviews cases which support the view that parts of the left hemisphere control languages, no matter how it is expressed, while right-side regions are involved only in skilled nonlinguistic movements and perceptions. Compares recent findings with previously held theories. (ML)

Twenty-four adults with mild mental retardation were compared with equal-mental age children and adults without mental retardation on tactile processing asymmetries. Results suggest that hemispheric processing is dependent on information processing requirements rather than type of stimulus. (Author/JDD)

This study explored the hypothesis that Japanese children perform significantly better on simultaneous processing than on sequential processing. The Kaufman Assessment Battery for Children (K-ABC) served as the criterion of the two types of mental processing. Regression equations to predict Sequential and Simultaneous processing from McCarthy…

Evaluates the effects on the 4MAT system on achievement and retention of learning. Defines 4MAT system as instructional model that provides systematic approach to organizing and delivering instruction that addresses learning styles and hemispheric preferences of students. Study examines students' interest in content and attitudes toward…
