INJURY TO THE NERVOUS SYSTEM CAN RESULT IN DEFECTS OF FIGURE FORMATION SUCH AS LACK OF PRECISION OF FIGURE AND UNCERTAINTY AS TO WHICH IS FIGURE AND WHICH IS GROUND. IMPAIRMENT OF FIGURE GROUND PROCESSES MAY BE LIMITED TO ONE AREA OF THE NERVOUS SYSTEM FUNCTION. DISTURBANCE IN FIGURE FORMATION MAY NOT RESULT IN PERCEPTION DISTURBANCES, DEPENDING…

Traditional medical interventions for the management of pain have consisted largely of either pharmacological treatments or surgery to interrupt the involved neural pathways. The results of these procedures have been largely unsatisfactory because of debilitating side effects and recurrence of pain. Investigations of a host of psychological…

The structure and function of the nervous system as it puts us into contact with our environment is described. Section 1 presents a detailed discussion of the structure of the brain, drawing an analogy to a computer, and discusses the sensory input function. The transport system is then explained in a description of the transmission of sensory…

Man's long period of cerebral growth has important implications for education. The brain goes through major developmental changes after birth, and researchers have suggested that this growth process presents an opportunity for fostering the plasticity of genetically determined connections. Animal studies show that postnatal growth of the brain is…

An experimental study of the efficiency of human information processing is based on the Bayesian model for simple hypothesis testing with fixed binomial sampling. Each of 60 subjects is analyzed with separate ANOVAs focusing on two efficiency variables. Sample size and critical value are also analyzed. Subjects show very different utilization of…

Activities are given for a concept guide to help students improve their thinking skills through conceptual awareness.

Considers the two cerebral hemispheres and their related functions as well as the understanding of how they can affect future educational planning. The right hemisphere, responsible for intuitive and creative processes, has been almost totally ignored in our society. Discusses the role of the art teacher in correcting that imbalance. (RK)

The physical identity reaction time task used in this study was designed to further test the effect of processing mode uncertainty on visual field asymmetries that Swanson et al. (1974) reported, and to determine the effects of location uncertainty in a cognitive task. (Author/KC)

Available from: British Medical Journal, 1172 Commonwealth Avenue, Boston, Massachusetts 02134. In order to determine whether Central Nervous System irradiation effects intellectual abilities, 28 children in remission at least 2 years after completing chemotherapy for acute lymphoblastic leukemia were assessed on standardized psychological tests…

This article describes a simulation designed to illustrate the electrical behavior of excitable membranes. The simulator, based on the Hodgkin-Huxley Model of the Membrane, is a simple devie that allows the student to see the consequences of changing equilibrium potentials and conductances. Numerous illustrations are included. (Author/MA)

The lateral eye movement paradigm was employed to test the hypothesis that narrow categorizers, who are believed to be more analytic in information processing, make characteristic use of the left hemisphere, while broad categorizers, being more holistic, depend more on the right hemisphere. Results are discussed in terms of cerebral specialization…

Argues that awareness of neuro-biology is necessary to insure accountability and to remain cognizant of the developing technology in this area, whose impact on the black community is increasing. It is up to the community and to black professionals to insure accountability, since scientists (and certainly those people who utilize this technology)…

These experiments were designed to assess the linguistic performance of the right hemisphere by using reaction time (RT) to measure the flow of information in the normal brain. RT to lateralized stimuli has proved to be a powerful tool for detecting functional differences between the hemispheres on a variety of cognitive tasks. (Author/RK)

Centers on the opinions of Michael Lawlor of the Society for Effective Affective Learning (S.E.A.L.) about "right brain" language learning and includes suggestions (with examples presented about learning Greek) for developing one's power of suggestion and applying it to foreign language learning.
