Most of 32 learning disabled children (seven to 14 years old) with neurological lateralization characteristics marked by right and left hemispheres had a normal CT (computerized tomography) scan. (CL)

Five male learning disabled students (eight to 13 years old) learned more words using the nonpreferred hand in tactile processing to remediate reading than with the preferred hand. (CL)

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.…

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…

This study used cued dichotic listening to investigate differences in language lateralization among right-handed (control), left handed, bilingual, and learning disabled children. Subjects (N=60) ranging in age from 7-13 years were administered a consonant-vowel-consonant dichotic paradigm with three experimental conditions (free recall, directed…

Past research has suggested memory, writing speed, and paired-associate learning rate to be important in WISC-R (Wechsler Intelligence Scale for Children Revised) coding performance. Suggested that visual perceptual factors also may be important and that coding performance in right-handed persons may be especially sensitive to integrity of the…

This report discusses the outcomes of a study of 147 children (ages 7-10) with learning disabilities that investigated the extent to which students legally classified with learning disabilities concurrently manifested mixed lateral dominance (MLD). The study was conducted to determine if MLD was a possible predictive factor for early…

Discusses some current concepts of the laterality/reading relationship. An overview of Samuel T. Orton's hypotheses of cerebral dominance and "strephosymbolia" is provided, and both visual half-field and dichotic listening studies as direct, empirical tests of laterality are discussed. (MKM)
