Descriptive Method

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

The Right

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 aims of this study were to develop and validate an instrument to quantitatively assess the handedness of basketballers in basketball tasks (Basketball Handedness Inventory, BaHI) and to compare it with their handedness in daily activities by the Edinburgh Handedness Inventory (EHI). The participants were 111 basketballers and 40 controls. All subjects completed the EHI and only basketballers filled in the BaHI. To validate the BaHI, a voluntary subsample of basketballers repeated the BaHI. Exploratory and confirmatory factor analyses supported a two-factor model. Our results show that: (i) Handedness score (R) in daily actions did not differ between basketball players (R by EHI = 69.3 ± 44.6) and the control group (R by EHI = 64.5 ± 58.6); (ii) basketballers more frequently favored performing certain sport tasks with the left hand or mixed hands (as highlighted by R by BaHI = 50.1 ± 47.1), although their choice was primarily the right hand in everyday gestures; and (iii) this preference was especially true for athletes at the highest levels of performance (R by BaHI of A1 league = 38.6 ± 58.3) and for those playing in selected roles (point guard’s R = 29.4 ± 67.4). Our findings suggest that professional training induces handedness changes in basketball tasks. The BaHI provides a valid and reliable measure of the skilled hand in basketball. This will allow coaches to assess mastery of the ball according to the hand used by the athlete in the different tasks and roles.

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.

Abstract The combination of the restoration location, the hand preference of the operator using the light-curing unit (LCU), and the design of the LCU all can have an impact on the amount of the light delivered to the restoration. To evaluate the effect of left-handed or right-handed users, the position of the operator (dentist or assistant), and the LCU design on the irradiance, radiant exposure and emission spectrum delivered to the same posterior tooth. Two light emitting diode (LED) LCUs were tested: an angulated monowave LCU Radii-Cal (SDI, Victoria, Australia) and a straight aligned multi-peak LCU Valo Cordless (Ultradent, South Jordan, UT, USA). The irradiance values (mW/cm2), radiant exposure (J/cm2) and emission spectrum were measured using a sensor in maxillary left second molar tooth. The irradiance and radiant exposure were analyzed using three-way ANOVA followed by Tukey test (a=0.05). The emission spectra (nm) were analyzed descriptively. The interaction between LCU design, operator position, and hand preference significantly influenced the irradiance and radiant exposure (P<0.001). In all cases, Valo delivered significantly higher irradiance than Radii-Cal. The handedness and the operator position affected the irradiance and radiant exposure delivered from Valo. Operator position and access affect the irradiance and radiant exposure delivered to the maxillary left second molar. The irradiance and radiant exposure can be greater when a right-hand operator is positioned on the right side of the chair and a left-hand operator is positioned on the left side of the chair. This may result in better resin composite polymerization.

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.

Previous research has discussed the interaction of hand preference, eye dominance, and sport performance. In this study, the relation of eye dominance with performance and subjective ratings in golf putting was investigated. 47 right-handed Japanese students from a college of physical education putted 10 balls to a drawn circle 3 m away, each under right-handed and left-handed stance conditions. Putting performance was measured by the number of successful putts. After putting in each condition, they rated subjective visibility and feelings of hitting. Analyses indicated that right-eyed subjects had significantly better performance using the right-handed stance than the left-handed stance, whereas left-eyed subjects showed the opposite. Most subjective ratings were more positive with right-handed stance for both right-eyed and left-eyed subjects. These findings suggest that eye dominance could have some influence on putting performance of Japanese novice golfers.

Hand-grip strength, measured by a hand dynamometer, was compared with hand preference for writing in a sample of 173 male and female undergraduate students. Hand preference and performance correlated significantly, but superiority of hand grip for 24% of the subjects did not coincide with the preferred hand. Hand-grip performance was not an accurate predictor of hand preference, and neuropsychological inferences on the basis of hand performance should be made cautiously. No significant differences were found between the right/left ratio scores for males and females, or order conditions.

The present study aims to compare the strength of right and left legs and reaction times of soccer players depending on their hand and foot preferences. The study included 92 volunteers chosen from amateur soccer players. The measurements conducted on the subjects were anthropometric characteristics, foot reaction times (sound, light) and right and left foot squat parameters. The t-test was used for statistical procedures. Among the amateur soccer players who participated in this study, it was found that 19.57% used left hand and 67.39% used right hand as preferred. Soccer players using both hands equally were found with a rate of 13.4%. In terms of foot preference, it was found that 22.83% of the participants used left foot and 43.48% of the participants used right foot as preferred. The soccer players using both feet equally was found as 33.70%. No significant difference was found between right handers and left handers in reaction time measurements when the soccer players were grouped by hand preference. When compared with left footed players (0.29 sec), only the right foot sound reaction time of right footed players was significantly shorter (0.21 sec) at p<. 05 level. Statistically significant correlation was found between soccer players’ hand and foot preference at a level of p< 0.01. Left footed players had significantly higher left leg mean squat (37.19 kg) when compared with right footed players (32.27 kg). No significant difference was found between right footed (35.36 kg) and left footed (33.98) subjects in terms of mean of right leg squat. Conclusion: According to the hand preference, the proportion of those who use equally two feet increased. Reaction times and force's squat of the dominant hands and feet were better. Training programs for soccer players planned according to individual characteristics including footedness may result in performance increase and decrease in injury as a result of reduced strength and reaction time asymmetry between legs and arms.

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.

Speed Accuracy

The aim of the study was to establish the differences in men and women’s performance of speed-accuracy movements with their left (LH) and right (RH) hands. The research participants were 24 healthy right-handed subjects: 12 males (aged 20.8 ± 1.1 years) and 12 females (aged 21.4 ± 1.0 years). The research was carried out in the Laboratory of Human Motor Control at the Lithuanian Academy of Physical Education (LAPE) applying the analyzer of dynamic parameters of human leg and arm movement (DPA-1; Patent No. 5251; 2005 08 25), which is used for the qualitative estimation of the dynamic parameters of one arm and leg target movement, two arms and legs coordinated and independent target movements, when the resistance power and target are coded with different programmable parameters. The task was performed with the right and then with the left hand (50 repetitions with each hand). The subjects had two tasks: a) to react as quickly as possible (simple task); b) to react as quickly as possible and to hit the target on a computer screen quickly and accurately (complicated task). We registered the maximal and mean movement speed, reaction time, movement trajectory and intraindividual variability of the right and the left hands. Conclusions. There was no significant difference in accuracy between female and male subjects, thought female subjects performed speed-accuracy task more slowly than men. Both males and females performed the speed-accuracy task with their right hand faster and more accurately than with their left hand. Performing movements with different hands the indices of reaction time did not differ significantly. Both males and females performed movements with their right and left hands with the same intraindividual variability.Keywords: movement control, reaction time, speed-accuracy task, right and left hand, gender.
