The brain's capability to apprehend complex information at multiple levels is ignored when teaching is limited to rote or "symbol-specific" learning. Educators should be concerned with increasing neurological networks or "maps" representing richness of content, instead of teaching isolated, segmented facts along well-worn…

In an effort to explore S. Orton's "intergrading" hypothesis, six developmental dyslexics (ages 16 to 47) and four good readers were tested on measures of interhemispheric coordination. Dyslexics showed reduced laterality bias and longer response latencies to bihemifield stimuli. (Author/DB)

Continuing dramatic developments in the ability of neuroscientists to peer inside the brain to discover its incredible intricacy places awesome responsibility on all educators to "do the right thing" for their students. Here, the authors offer readers powerful brain-compatible and research-based teaching and learning strategies based on how the…

Analysis of use of positron emission tomographic measurements of resting-state regional cerebral blood flow in 29 men, 10 of whom stuttered, did not support the idea that developmental stuttering is associated with abnormalities of blood flow at rest. Findings did suggest an essentially normal functional brain terrain with a small number of minor…

Quantitative EEG magnitude data were obtained from children with and without attention deficit disorder (ADD). The data suggest that the right fronto-centro-temporal region is not as "cognitively activated" relative to the left hemisphere in those children with ADD. Neurotherapy training of the right frontal and central regions in ADD…

Examines research that suggests there are physiological differences between male and female brains. Considers the implications for adult education. (SK)

Presents data from a patient with a progressive fluent aphasia, who exhibited a severe verbal impairment but a relatively preserved access to knowledge from pictures. Argues for a distributed, multi-modality system for semantic memory in which information is stored in different brain regions and in different representational formats. (Author/VWL)

Two studies examined the ability to assign thematic roles and to coindex referentially dependent noun phrases in closed head injured adults (N=20), adult stroke patients (N=20), and normal adults (N=20). Results suggested that syntactic comprehension disturbances are similar following left cerebral hemisphere infarction and closed head injury.…

The mechanisms of both language-based and non-language-based learning disabilities are presented within the framework of central nervous system development and the compromises to that development that arise from genetic, hormonal, antibody, medication, and postnatal compromises. Also reviewed is the need for a taxonomy of learning disabilities.…

To test for interhemispheric difficulties associated with dyslexia, this study assessed bimanual coordination in dyslexic and nondisabled boys using an Etch-a-Sketch-like task. Dyslexics showed significant impairments on mirror movements, and often unknowingly reverted to parallel movements when visual feedback was removed. (RH)

This study explored whether the "right thinking style" relates to creativity as measured by 2 types of creativity tests, which were given to 109 undergraduates. Results correlated the How Do You Think scores positively with right thinking scores on the Your Style of Learning and Thinking test and negatively with left thinking scores.…

A resurgence of interest in the relationship between cerebral lateralization (the functional asymmetry of the cerebral cortex) and aggression has occurred. Most recent studies have found that individuals with abnormal patterns of lateralization are overrepresented among violent individuals. Intervening variables (such as drug and alcohol abuse)…

Brain imaging research allows direct assessment of structural and functional brain abnormalities, and thereby provides an improved methodology for studying neurobiological factors predisposing to violent and aggressive behavior. This paper reviews 20 brain imaging studies using four different types of neuroimaging techniques that were conducted in…

Discusses development of the Sonnier Model of Hemispheric Preference. Notes frequent references to the senses "visual" and "auditory" rather than the two hemispheric functions "visual" and "analytical." (RS)

It is proposed that there is a modular but interconnected system underlying the perceived hierarchical organization of objects. The discussion centers on neural and cognitive mechanisms of organizing objects within objects in at least four separate subsystems. (SLD)
