This paper attempts to examine the research of split-brain, hemispheric specialization, and brain function, as it pertains to handwriting, brain wave patterns, and lateral differences. Studies are reviewed which point to asymmetric differentiated functions and capacities of the two cerebral hemispheres in split-brain patients and in normal…

This article presents information drawn from research on brain processes that impact perception, memory, learning, and understandings about the world. This information is related to the use of interactive video and the Web in distance education through a discussion of how best to enhance learning--or mitigate problems caused--through the use of…

Examination of existing empirical and theoretical literature suggests there is no conclusive support for the existence of a critical period for human speech learning. Assumption of a critical period may inhibit the search for testable hypotheses concerning observed adult-child differences in second language production. (Author/LMO)

This paper describes recent advances in split-brain research and summarizes the qualities characterizing the two cerebral hemispheres. Traditional patterns of education, it is argued, are inadequate since they concentrate almost exclusively on the left hemisphere. Teaching strategies and school experiences are suggested to accelerate right…

Findings are related from a study designed to determine the effect of verbal-only, imagery-only, and integrated (verbal-to-imaginal) strategies on third graders' (N=111) levels of economic reasoning (use or nonuse of cost-benefit analysis) in their personal decision making. Implications of these findings for curriculum planning are discussed.…

Fleeting electrochemical connections made between brain cells help people remember the thoughts, skills, experiences, and knowledge that make them unique. Presents the dissection of the brain of a sheep, an animal in which brain structure and function are similar to that in humans, to demonstrate where these processes take place. (PVD)

Background: Sex-differences exist in some areas of human social behaviour. In animals, foetal testosterone (fT) plays a central role in organising the brain and in later social behaviour. fT has also been implicated in language development, eye-contact, and spatial ability in humans. Methods: Fifty-eight children (35 male and 23 female), whose fT…

Background: Psychophysiological measurement of processes related to social behavior may be valuable for research on individual differences and subgroups among children with autism spectrum disorders (Coleman, 1987; Dawson, Klinger, Panagiotides, Lewy, & Castelloe, 1995; Modahl et al., 1998). In particular, recent research and theory suggests that…

Environmental restriction or deprivation early in development can induce social, cognitive, affective, and motor abnormalities similar to those associated with autism. Conversely, rearing animals in larger, more complex environments results in enhanced brain structure and function, including increased brain weight, dendritic branching,…

An experiment was conducted to examine whether perceptual information, specifically the shape of objects, is activated during semantic processing. Subjects judged whether a target word was related to a prime word. Prime-target pairs that were not associated, but whose referents had similar shapes (e.g. LADDER-RAILROAD) yielded longer ''no''…

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,…

Recent advances in neuroscience describe the effect of experience on neural architecture. Paralleling these advances in neuroscience, recent explorations in the field of art therapy speculate on the relationship between specific therapeutic interventions and neuroplasticity, which underlies the changes in neural architecture. One such…

The purpose of this paper is to provide a conceptual foundation for the development of hypermedia as an instructional tool for addressing individual learning style differences. Various learning theories and their relationship to hypermedia are examined, including information processing theory, semantic networks, concept webbing/mapping,…

4MAT is an 8-step, sequential instructional model based on two theoretical constructs: Kolb's model of learning styles and the concept of brain hemisphericity. The model, developed by B. McCarthy (1987), is derived by interacting each of Kolb's four quadrants with both left and right brain. Kolb outlined four learning styles based on the four…

A review of research makes it increasingly clear that findings from the areas of brain development and hemispheric specialization, student and teacher learning styles, and holistic and meaning-centered approaches to reading and writing are related, as they all contribute to a richer view of how learners learn. In brain research, the popular focus…
