This article first outlines a tentative neurocognitive model of oral language and reading. It then reviews recent functional magnetic resonance imaging studies of the development of oral language and reading and brain-imaging research on dyslexia in light of the proposed neurocognitive model. Finally, research on the plasticity of neural systems…

A recent development by neuroscience is neuroimaging, a method of looking into the "black box" of the brain while people are feeling, doing, and thinking in real time. The first fMRI study of bereavement has recently been published, and the present article summarizes it in non-specialist language, focusing on its theoretical and clinical…

Recent studies of redundancy gain indicate that it is especially large when redundant stimuli are presented to different hemispheres of an individual without a functioning corpus callosum. This suggests the hypothesis that responses to redundant stimuli are speeded partly because both hemispheres are involved in the activation of the response. A…

The article proposes a dynamic-developmental-interaction approach to individuals with learning disabilities (LD) which addresses the absence of certain fundamental ego skills. Emotional conomitants to LD (such as low frustration tolerance and overcompensation) are noted, and intervention techniques based on the dynamic-developmental interaction…

Current models of communication fear and avoidance are analyzed (i.e., genetic, social and interactional). A new model is proposed, linking language, imagery, emotion, and behavior to complex neurological systems in the brain. Evidence for the model is taken from several related fields of study, especially neurolinguistics, neuropsychology,…

A report which describes a theory and corresponding model for the neural basis of language. A detailed functional description is given for elementary visual-linguistic processes. (Author)

Connectionist (parallel distributed processing) modeling provides a new way to approach the neurological study of language. This method focuses on the interplay between a computational model and the appropriate neurological, neuropsychological, and speech and language data, couched in connectionist mechanisms that map naturally to what is known of…

Explains the concept of stretch reflexes to students using a mechanical model. The model provides a dynamic multisensory experience using movement, light, and sound. Describes the construction design. (SAH)

Summarizes research done on the resting and action potential of nerve impulses, electrical excitation of nerve cells, electrical properties of Nitella, and temperature effects on action potential. (GS)

This paper examines the influence of Norman Geschwind's model of connectionism, in which complex functions are built up by connecting primary areas in the brain, and notes his studies of the effects of disconnection on dyslexic individuals. Connectionist-based behavioral studies are reviewed, focusing on intracortical association connections and…

Investigative explanations of how the mind works and elaborates on the research and findings developed from a neurocognitive connectionist model. Presents several examples and illustrations of how the human brain may generate rules, recognize patterns, and adapt. (ML)

Historically described are research studies which led to the current explanation of the two kinds of intracellular transport-axoplasmic flow and axoral transport. Models explaining their fundamental mechanism and the kinds of materials they convey are presented. (BT)

The paper, part of an all-day workshop, reviews research and theory on left-right hemisphere information processing and psychophysiological models on the functional organization of the brain. Hemisphericity is considered in terms of language, cognitive styles, role in education, verbal and non-verbal processing, affective concomitants, and…

This paper proposes a reading model based on the metaphorical usage of neurobiological knowledge. The basic units, organization, and functioning of the Nurogen Model are described. The model's empirical scope is discussed focusing on letter and word perception, theme effects in comprehension, and the influences of text characteristics upon…

A new method generates specific predictions concerning the expected frequencies of aphasia after unilateral injury to the brain in the left- and right-handed. These predictions are then compared with the observed data for all known studies between 1935 and 1973 to derive the best-fitting model of hemispheric speech lateralization in the left- and…
