TWO DISPARATE STUDIES WERE REPLICATED WITH A PUBLIC SCHOOL POPULATION USED BY HILLERICH IN A 4-YEAR STUDY OF THE DEVELOPMENT OF HANDEDNESS AND EYEDNESS. SUBJECTS WERE 273 SEVENTH AND EIGHTH GRADERS WHO REMAINED FROM AN ORIGINAL POPULATION OF 400. TESTS WERE ADMINISTERED TO DETERMINE EYE DOMINANCE, HANDEDNESS, CONTROLLING EYE, READING ACHIEVEMENT,…

ASPECTS OF NEUROLOGICAL RESEARCH ARE PRESENTED UNDER THE TOPICS OF NEUROLOGICAL GROWTH AND DEVELOPMENT, CEREBRAL DOMINANCE, "SPLIT-BRAIN" SYNDROME, AND SEQUENCING. THE FIRST TWO AREAS INDICATE THAT ASSESSMENT OF A CHILD'S NEUROLOGICAL DEVELOPMENT MUST TAKE INTO ACCOUNT VARIATION OF RATE AND DEGREE OF DEVELOPMENT, AND THAT THE SIGNIFICANCE OF…

Hypnosis was combined with sensory and motor stimulation to remediate reversal problems in five children (6 1/2- 9-years-old). Under hypnosis Ss were given the suggestion that they learn their numbers through feel and then given 1 hour of structured instruction daily for 10 days. Instruction stressed conditioning, vibratory memory, touch memory,…

The effects of laterality, movement, and language on children's ability to conserve multiple space relations were investigated in this study of visuo-spatial dimensionality acquisition. The sample for the experiment consisted of 160 first-graders (80 boys, 80 girls) who were matched on intelligence and socioeconomic status. These subjects were…

Reported was an explanatory conceptual model for pathological left-handedness (PLH) and related hypotheses, some of which could not be tested empirically due to lack of information. The model was reported to provide an explanation for the relationship between handedness and specific learning disability, and handedness and cerebral dominance for…

Two tachistoscopic tests of cerebral lateralization, one measuring spatial functions and one measuring verbal function, were administered to 73 subjects classified by handedness, hand posture writing, and sex. Tests the proposal that an inverted hand posture is indicative of a language hemisphere ipsalateral to the dominant hand and that the…

Provides findings of a study in which it was found that asymmetries in the size of the two feet were strongly related to sex and handedness; right-handed males having larger right feet and right-handed females having larger left feet, the reverse being seen in non-right-handed individuals. Differences were apparent in children even younger than…

Twenty-nine male and 35 female right-handed children, aged five to seven, were assessed for the effect of familial sinistrality left-handedness on a rapid color-naming task. Controlling for age and family size, a significant effect for degree of familial sinistrality was found in the girls but not in the boys. (Author)

It is proposed that in the process of letter perception a preliminary nonverbal code is available in the right hemisphere until superceded by a verbal code in the left hemisphere. (Editor)

Author studied the capacity of the normal brain to carry out a paired-associate learning task by projecting the stimulus material to either the right or left hemisphere in order to establish if there was a lateral specialization for this type of learning in the normal brain. (Author/RK)

This paper described findings which accounted for the coexistence of positive and negative results in previous reports and showed how the findings can be explained by a theory of the origin of handedness. (Author/RK)

Hemifield differences in the recognition of briefly presented words were investigated in children ranging in grade level from second grade through college. (Editor)

Report summarizes the activities of a team of researchers in seven pre-school centers on Long Island, between October 1967 and April 1968. Aim of the project was to find a normative base for the construction of a new curriculum for pre-school children, in particular for those labeled disadvantaged.'' (Authors/CB)
