Compared four-year-old left-handed children and children lacking definite hand preference with right-handers on motor skills. Found no differences between left-handers and right-handers of either sex, but the children lacking hand preference had lower scores. Possible sex differences and implications for the education of children lacking…

Comparison of 28 gifted and 20 normal young children suggested that the gifted child is not neccessarily gifted in all areas. In general, sex and handedness history operate similarly in the gifted and normal groups; males perform better than females and the right-handed children perform better than left-handed children.

The extent to which sex differences on a mental rotation test were related to ocular dominance, handedness, and familial handedness was explored. The Vandenberg revision of the Shepard-Metzlar mental rotation test was administered to 206 college students. The test consisted of 20 criterion figures, each followed by two correct and two incorrect…

A figural form of the Torrance Tests of Creative Thinking was administered to 96 left-handed and 96 right-handed individuals. The left-handed subjects demonstrated greater creativity than the right-handed; females scored higher than males; and college-educated subjects scored higher than those with no college. (Author/BW)

Reports two studies which examined the relationship among (1) the ability to determine horizontality, (2) a general test of spatial abilities, and (3) hemispheric activation as measured by lateral eye movements. (JMB)

Left-hemisphere language specialization in right-handed children was tested in children previously classified as consistent or nonconsistent in their hand preference. Results showed that both male hand preference groups demonstrated asymmetric interference in dual task tapping performance. In contrast, only females associated with consistency in…

Aims to obtain prevalence figures for left-handedness among 10-year-old Swedish children; to replicate some findings concerning Bishop's (1980) extended pathological left-handedness hypothesis; to evaluate the influence of factors such as the child's sex and reduced optimality in the pre-, peri-, and neonatal period; and to determine the…

This study attempted to gather baseline data on a randomly selected population of 353 kindergarten and first-grade children for consistency of response in hand dominance measures and eye dominance measures and for comparison by sex, race, maturity and socioeconomic status. (Author/SB)

Spatial and sequential tasks performed both independently and jointly were compared for 40 undergraduates grouped by sex and dominant hand. When both tasks were performed simutaneously, there was a significant advantage for right-handers and a slight advantage for males. This was attributed to hemispheric interference left-handers experienced.…

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)

Examined consistency of hand preference in a longitudinal study of children between 18 and 42 months of age. Results showed a sex-specific relationship between hand consistence and intellectual development. Females with consistency of handedness were precocious compared to females without such consistency; the same relationship did not hold for…

This study measured test-retest reliabilities and interrelationships of four common measures of lateral dominance: dowel balancing, peg placement, grip strength, and conjugate lateral eye movement. Moderate reliabilities for all measures except grip strength were obtained. Subjects' sex may be an important reliability variable. Correlations among…
