Dyslexia appears to be a meaningless label attached to children with reading problems; the label only leads to confusion rather than clarity. (JH)

The magnitude of the dichotic right ear advantage was assessed in 48 normal and 48 learning disabled (LD) children (mean age 8.3 years). Ss were matched according to age, sex, and handedness. An analysis of results indicated a significant right ear advantage in both the normal and LD children, but revealed no developmental trend for either group.…

THE RESULTS FROM AN EXPERIMENT TESTING A SERIES OF SIX HYPOTHESES DEDUCED FROM THE DELACATO INTERPRETATION OF NEUROLOGICAL ORGANIZATION ARE PRESENTED. SUBJECTS IN THE 3-MONTH STUDY WERE SECOND GRADERS FROM THE CHICAGO ARCHDIOCESAN SCHOOL SYSTEM WHO REPRESENTED SIMILAR BACKGROUNDS AND SOCIOECONOMIC LEVELS. COMPARISONS WERE MADE OF THE READING AND…

Examined with 23 children (7-10 years old) with minimal brain dysfunction was the relation of handedness functions to early and diffuse brain damage. Ss and a group of 25 controls were given the Harris Tests for Lateral Dominance and the Halstead Finger Oscillation test. Results indicated a lowered performance level for both right and left hands…

Examined with 38 right-handed boys who were either dyslexic or normal readers and matched for age and IQ (mean age both groups=10.6, mean IQ normal readers=106, mean IQ dyslexic readers=105) were the weak, strong, and equal lateralization theories of dyslexia. Cerebral lateralization was measured for linguistic material (digits) using the dichotic…

Research on laterality and intellectual abilities suggests that left-handed persons may be divided into two categories: one not discriminably different from those who are right-handed, and one deficient in intellectual and cognitive abilities. 7688 children were tested on handedness, intellectual performance, and scholastic aptitude in order to…

Discusses the relevance of the study of the neurobiology of cognitive development, for an understanding of both the neural bases and the nature of cognition. Also considered are the age at which hemisphere specialization first appears and whether hemisphere specialization changes over time. (PCB)

Self-report subscale scores from the Herrmann Brain Dominance Survey and Torrance and Reynolds' Your Style of Learning and Thinking were correlated with the College Board Scholastic Aptitude Test Scores and with the grade point averages of 40 junior female occupational therapy students.

Research indicates that deaf individuals do not develop the usual hemispheric specialization for verbal and nonverbal processing and that early severe hearing impairment influences the lateral organization of the brain for interpreting linguistic information. Possible instructional implications include encouraging an early symbol system for…

Investigates hemispheric asymmetries in children for processing auditory material which varies in emotional intonation or verbal content. Children in kindergarten, fourth, and eighth grades reported on the emotional and verbal content of dichotically presented sentences. Findings indicate that the right hemisphere is specialized for mediating…

Hemispheric specialization tasks were given to different-aged boys. Asymmetries were demonstrated on manual, visual, and auditory tasks; however, the degree of asymmetries did not change across age groups. There appears to be a dissociation between visual and auditory perceptual asymmetries. (Author/RD)

Apparent ambiguities in Levy and Reid's writing posture criteria and dissimilar criteria used by other investigators are discussed. This review suggests that an adequate test of hypothesized relations among handedness, hand posture during writing, sex, and cerebral organization requires development of a standard set of valid criteria for writing…
