The article focuses on the factors that have led to the current interest in the neuropsychology of learning disorders. The validity of the neuropsychological model is examined. Research regarding the neurobiological basis of learning disorders, cerebral asymmetries, and neuropsychological assessment batteries for learning disabilities are…

Shows how the spatial elements in reading matter contribute to its meaning. The importance of breaking up any complicated passage into fragments which are easy to understand is emphasized. (Author/RK)

The basis of modern learning theory is questioned in view of Popper's philosophy and the anatomy and physiology of the nervous system. (Editor)

Research shows that children of about 10 years can remember photographs of faces upside down almost as well as those shown upright and are easily fooled by simple disguises. This ability to encode orientation-specific configurations of a face may reflect maturational changes in the right cerebral hemisphere. (MLH)

A discussion of the Selcuk Network, a scheme which achieves response routing on the basis of strictly local information, pursuant to the broadcast of a general message, it has applicability to content-based addressing and to computor-to-computer communication nets. (Author)

Consistently over the three test situations, initial left-handedness' gives way during the third quarter of the first year to right-hand dominance. The way in which the shift occurs lends support to a maturational, rather than a learning or social pressure explanation of lateral asymmetry. (Author/CB)

Results of an experiment in which two speech sounds were presented simultaneously to the two ears in normal and unilaterally brain-damaged subjects suggest a role for the nondominant cerebral hemisphere in processing and/or storage of competing speech stimuli. (KW)

A total of 20 children with idiopathic precocious puberty; 27 adolescents with clinically delayed puberty; and an equivalent number of controls matched for sex, age, and IQ were given a battery of tests including measures of verbal and spatial abilities and a task using a dichotic listening procedure to assess hemispheric lateralization.…

Using a question-and-answer format, the author discusses brain research, its relationship to existing learning theory, left- and right-brain differences and their relationship to logical thinking, brain growth spurts, learning styles, and the effects of future brain knowledge on learning, especially on schools' development of brain-compatible…

A quantitative model of speech development is proposed based on observations of normal hearing and congenitally deaf children. Nonlinear controls used during the development of suprasegmental and segmental aspects of speech are identified. Linguistic components of speech are ignored. The importance of the associative cortex in speech-motor control…

Connectionistic notions of hemispheric specialization and use are incompatible with the network organization of the human brain. Although brain organization has correspondence with phenomena at more complex levels of analysis, the correspondence is not categorical in nature, as has been claimed by the left-brain/right-brain theorists. (Author/GC)

Describes the relationship between neonatal crying and anthropometric indices of fetal growth. No differences were found between cry features of underweight and overweight infants; both groups required more stimulation than average weight infants to elicit crying. It is suggested that certain cry features may reflect the risk status of neonates…

Part Two of the article focuses on the development of manual motor skills in learning disabled children. After a discussion of test methods, the author considers aspects of a medical examination, including a general exam, a neurological exam, an electroencephalogram, and a diagnostic test of hand/motor skill development. (For Part One, see EC 123…
