After tachistoscopic exposure of a row of letters, recall functions show bowing and skewedness similar to the standard serial position curve that results from sequential presentation of elements. A similar curve is generated by recall of binary elements presented briefly and simultaneously. Prior investigators have interpreted this effect as an…

Developmental and post-traumatic dyslexia are discussed in terms of a dysfunction of the central nervous system resulting in reading disabilities. The relationship of reading to other language functions is considered, with emphasis on the temporal aspects of speech and reading. An interdisciplinary approach is held necessary for the diagnosis of…

Research into visual, perceptual, and motor coordination suggests that the kind of physical activity and coordination involved in swimming might prevent some cases of dyslexia and improve the academic performance of many learning disabled children. Early neurological development shows a relationship among the creeping period, later communication…

The study examined the hemispheric laterality of 39 deaf children in the upper primary and intermediate grades. (Author)

Reports on structural asymmetrics between the hemispheres which are found in the human brain. Auditory region and Sylvian Fissure asymmetry have also been observed in the fetus and in other primates. Describes research which has correlated asymmetries with hand preference, certain childhood learning disabilities and some dementing illnesses of…

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…

Investigates the relationship between the perinatal hormonal environment and the development of cognitive sex differences. Compares 25 upper class women aged 14 to 24 who were exposed prenatally to diethylstilbestrol (DES) and their unexposed sisters. Subjects show a more masculine pattern of lateralization than their sisters but are similar in…

Investigated the relationship between hand writing posture and cerebral dominance of 48 left handed writers and 25 right handed writers. Determined that cerebral dominance is related to handedness and to whether or not the writing hand posture is normal or inverted. (SL)

Reviews research studies concerning grip strength as an indicator of hand dominance and presents data from a two-day study with ten normal and ten retarded right-dominant preschool children. (MB)

Lateral preferences as manifest in handedness, footedness, eyedness, and earedness were assessed in college students. Consistent right-handedness was most prevalent in language and literature majors. No relationships between major and other indexes of lateral preference were found. (Author/RD)
