The purpose of the study was to replicate findings of an earlier study of fourth grade boys manifesting mixed handedness with a sample. Among 32 mixed-handed boys in Grades 6 to 8, the right-handed writer, left-handed thrower group obtained low spelling scores (Normal Curve Equivalent Scores) on the California Achievement Test significantly more frequently than the left-handed writer, right-handed thrower group. These findings are consistent with data for Grade 4 boys in the earlier study. Findings strengthen the hypotheses that mixed handedness is not a unitary neuropsychological entity and that boys who write with the right hand and throw with the left hand might be at risk for certain academic deficits.

Normal Curve Equivalent Scores on subtests of the California Achievement Test for mixed-handed children, 52 boys and 58 girls from Grades 3 and 4, who are right- and left-handed writers, indicate no differences by handedness in girls, but among the mixed-handed fourth grade boys, those who wrote right-handed scored lower on Study Skills than the boys who wrote left-handed.

This study evaluated the literacy assignments elementary teachers use in their reading and language arts instruction, the reasons why they use a particular assignment, and how students react to different assignments. The project was initiated by teachers (three third-grade and three fourth-grade) and their principal because they believed students failed to see how various reading and language arts skills were related to one another, had difficulties applying such skills whenever they had to read or write lengthy prose, and did not want to complete assignments unless they received extrinsic rewards. Furthermore, teachers said teaching was no longer as satisfying as it had been in previous years. To evaluate their concerns we examined whether their literacy assignments included those characteristics that foster student learning and motivation and we interviewed the teachers and principal about why they believed teaching was no longer as satisfying as it had once been. Interviews indicated that teachers and the principal believed accountability pressures to increase standardized achievement test scores strongly influenced their school's reading and language arts instruction. Teachers said they attempted to raise students' scores by emphasizing the standardized achievement test skills. To maximize skill coverage, teachers said they avoided literacy assignments that required the reading of lengthy texts, sophisticated writing, and lengthy discussions. Evaluations of their literacy assignments confirmed their statements; students seldom completed classwork which required sophisticated writing or reading. Student interviews showed that they were bored with these assignments or did them because they expected extrinsic rewards. Whenever they completed a more complex literacy assignment (i.e., those that required the writing of single or multiple sentences or paragraphs), students said they were challenged and enjoyed learning for learning's sake. Discussion focuses on the implications of these findings for school improvement studies and students' learning and motivation.

Human has a preference to use their hands for various manual activities. Left-handed preference is people who tend to use their left hand to perform various manual activities, while right-handed people tend to use right-handed. Any researches show that the left-handed preference for more creativity was influenced by the dominant use of the right brain and bigger corpus callosum. The research aims to determine the percentage of left-handed preference and their creativity in Universitas Papua, Manokwari Papua Barat. The method used in this research is the descriptive method. Data collection used a questionnaire to evaluate individual hand preference using Handedness Questionnaire and to determine individual creativity using Adjective Check List. The percentage of left-handed people in UNIPA were 9.3% or lower than right-handed and higher than ambidextrous. Our study supports the statement about selection in handedness in the traditional society which showed a higher percentage of left-hander as advantages related to using hand intensively.  The percentage of left-handed males and females was almost equal and strongly left-handed was higher in females. The percentage of creative people was higher in left-handed, especially in males

Prior research has shown that right-handed adults perform better on a speed-tapping task with the right hand and right foot, while left-handers execute more rapidly with the left hand and right foot. Speculation is that environmental influence, most likely driving experience, may account for the right-foot bias. To examine this hypothesis further, 48 young right- and left-handed children were tested on a similar protocol. Analyses indicated no significant differences in foot performance within hand-preference groups. Since these findings do not complement reports for adults, factors such as experience or maturation might contribute to the difference. Were patterns similar, the effect of environmental influence would be assumed to be small. However, much more evidence is needed before an adequate explanation can be developed. The issue of possible environmental influence is discussed from various theoretical perspectives.

The connection between lateral dominance and force of handgrip was investigated by means of a repeated-measures design. 521 children participated. Performance on a paper-and-pencil task and force of handgrip were measured at the beginning of the first year at school and at the end of the first and of the second years at school. On the paper-and-pencil task 84% of the children were classified as right-handers, 8% as left-handers, and 8% as ambidexterous. About 2% of children classified as right-handers at the beginning of the first year at school were classified as left-handers at the end of the second year at school while 18% of left-handers shifted to right-handedness. 52% of children attained their best performance on handgrip with the right hand and 39% with the left hand. No differences could be found either for the right or for the left hand in force of handgrip between right- and left-handed and ambidexterous children. For right-handers, however, the more skilled hand showed superior performance in force of handgrip. These results indicate that left-handers are less strongly handed than right-handers.

Purpose: determining peculiarities of speed characteristics of hand movements of female boxers with different functional asymmetry types during dynamic work performance. Material: 50 highly skilled female boxers (masters of sports of international class, masters of sports). The study of female boxer psychomotor functions was designed according to a certain scheme. The motor component of motor response was examined by means of tapping test. The time of a simple and two complex visual-motor responses was determined. The study was completed by determining the identification time for visual stimuli of various degrees of complexity without a motor response. It was assumed that this will allow to consider the visual-gnostic component in a "pure" form. Such a design of the study permitted to evaluate the contribution of each component of psychomotor response to the response speed of female boxers with different types of functional hemispheric asymmetry (FHA) profile. Results: For the first time, the psychophysiological indices of female boxers were obtained. Female boxers were conditionally divided into right-handers, left-handers and ambidexters. The differences of these groups of female athletes in psychophysiological indices were established. Conclusions: In convenient mode, ambidexters perform work at a high rate than right-handers. At that, their right hand is faster than the left. The total number of movements performed by left-handers is greater than that of right-handers and ambidexters (it concerns both hands). The speed characteristics of female boxers with different types of functional asymmetry in accelerated mode are the same. The pace stability of right-handers and left-handers is high, but less than that of ambidexters. Ambidexters who use the right-handed stance are at advantage than right-handers with right-handed stance. Left-handed female athletes perform movements with greater speed than right-handed ones. For right-handed and left-handed female athletes it is more difficult to maintain the optimal pace of the right than the left hand, whereas ambidexters have problems with maintaining the optimal pace of the left hand. Left-handed female athletes are faster than right-handed ones.

AbstractIn the concern for inclusiveness, one area that has been largely neglected is the discrimination against left-handedness. This paper looks briefly at some of the scriptural and social stigmas and implications attached to left-handedness. Using Luther's theology of the cross as its basis, a left-handed theology is introduced. Arguing for the need for a theology which focuses on those who are marginalized, a left-handed theology offers a model whereby God's left hand offers to those who are in “minority” positions grace and solidarity. This is contrasted to the right hand of God, which portrays a God of power, strength, and triumphalism. The hand of God which one chooses to relate to determines, then, how one does theology, and how a theological inclusiveness is developed.

Comparison of the MMPI profiles of the right-handed (874 or 87%), left-handed (107 or 11%), and the ambidextrous (27 or 2%) subgroups within a sample of 1008 nuclear submariners showed no differences whatsoever (10% level). Moreover, the distributions for educational achievement level and verbal aptitude test scores were identical for the 3 groups.

This study investigates the effects of ipsilateral and crossed hand-eye dominance on one and both hands catching performance (OHCP and BHCP) in participants aged 10 to 13 years. The combined groups including hand and eye dominance consisted of right handed-right eyed (RHRE), right handed-left eyed (RHLE), left handed-left eyed (LHLE) and left handed-right eyed (LHRE), respectively. In this study the mean values were only higher in the favor of LHLE females in left hand OHCP from 2 and 3 m distances. In other side, LHLE males had a higher mean values not only in left hand OHCP from 2 and 3 meters but also in the right hand OHCP from 3 meters. No significant difference was observed in BHCP among four groups in both genders. In conclusion, ipsilateral handeye dominance is an advantage for OHCP compared to cross dominance. Also left side had an advantage compare to the right side in OHCP. Keywords: Hand dominance; physical activity; gender.
