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 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.

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

Components Analysis

Because of the still imperfectly understood basic factor structure of the MMPI, a Principal Components Analysis and Varimax Rotation was conducted on the MMPI item responses of 50 female undergraduate students of Education at Massey University. Eight factors were extracted which were named: Neuroticism, Anti-social behavior, Fundamentalist religiosity, Subjectivity, Introversion, Paranoic tendency, Depression and Physical symptoms. The possibly different factor structure for males and females needs explication in further work.

The influence of depression on the cerebral hemispheric motor functioning of 40 right-handed women, half of whom had been classified as depressed, the other half as nondepressed, was examined. The depressed women were also characterized by elevated state and trait anxiety, suggestive of an anxious-depressive state with heightened arousal. A hand dynamometer was used as a standardized measure of hemispheric motor functioning such as hand-grip strength, perseveration, and fatigue. Primary findings indicated that depressed women displayed significantly less perseveration at the left hand than did nondepressed women, but a nonsignificant trend only was noted for less perseveration at the right hand. These results suggest possible differential arousal of the left and right cerebral hemispheres in this sample of anxious-depressed women and are discussed in terms of arousal theory.

This study explored the influence exerted by celebrity endorsement on the purchase of slim tea products by female undergraduate students in universities in southeast Nigeria. Specifically, the study aimed to determine the relationship between the brand image of slime tea and celebrity endorsement, identify how celebrity choice influences the brand image of a product, and also examine how female undergraduate students’ choice of brand product is driven by celebrity influence. The population of this study consisted of female undergraduate students in the University of Nigeria Nsukka, Michael Okpara University of Agriculture Umudike, Madonna University Okija, and Ebonyi State University Abakiliki. A multistage sampling technique was used to arrive at a required sample size of 383. I did an oversampling and a total of 400 copies of the questionnaire were distributed and 392 copies of this questionnaire were filled and returned, making for a return rate of 98%. Findings from this study showed that respondents believe that celebrity endorsement can influence their brand choice. And that the choice of celebrity used matters a lot. If an organization fails to provide a positive and strong brand image, it may directly or indirectly affect consumers’ decision-making; as consumers may shift to competitors that offer a better experience. From the findings of this study, it is recommended that advertisers should make use of the right celebrities to enhance the brand image of their products and also consider celebrities whose profession and lifestyle are in sync with the products and services that they are endorsing.

The Right

There is persuasive but not decisive evidence that females reminisce more than males do because they accumulate more reactive inhibition during prerest trials. The present study provided a further test of this hypothesis within the context of a bilateral-transfer design. 80 subjects, 40 of each sex, practiced continuously with the right hand for five 1-min. trials on a mirror-tracking task. Subgroups of the sample then shifted to continuous left-hand practice after transition intervals of 0, 2.5, 5.0, or 7.5 min. As predicted from theory, the slope of the prerest practice curve was lower for females than for males, and females' inferiority on the first transfer trial declined as the length of the transition interval increased. Sex differences in left-hand performance trends were also consistent with theory.

Facial Images

Japanese male and female undergraduate students judged the gender of a variety of facial images. These images were combinations of the following facial parts: eyebrows, eyes, nose, mouth, and the face outline (cheek and chin). These parts were extracted from averaged facial images of Japanese males and females aged 18 and 19 years by means of the Facial Image Processing System. The results suggested that, in identifying gender, subjects performed identification on the basis of the eyebrows and the face outline, and both males and females were more likely to identify the faces as those of their own gender. The results are discussed in relation to previous studies, with particular attention paid to the matter of race differences.

Hypothesis Evaluation

Sex-related asymmetries in the ability to process different semantic categories have been reported both in normal subjects and in brain-damaged patients, but the nature of these asymmetries is still controversial. Some authors suggest that these differences might be due to social-role related familiarity factors, whereas others attribute them to inborn neural differences rooted in evolution. Drawing in part on this second line of thought, some authors have suggested that gender-related asymmetries might be due to differences in stimulus processing between men and women, namely, to the tendency of females to focus mainly on perceptual features and of males to focus equally on both perceptual and functional features. To test this hypothesis, we asked 53 male and 65 female undergraduate students to evaluate the relevance of a number of perceptual and functional features in the representation of various kinds of biological and artefact categories. Contrary to the hypothesis, evaluation of the weight of different sources of knowledge in representing living and artefact categories was similar in males and females.

33 male and 33 female undergraduate students were individually tested to determine the correlation between the perceived strength of an auditory and a tactile stimulus as measured by the subjective brightness of an adjustable light. While Ss discriminated between the relative strengths of the stimuli in each condition, there was no agreement as to the brightness of the light for each treatment. Also, there was no difference between responses by males and females.

Prior studies have proven the existence of the "hearing aid effect" when photographs of Caucasian males and females wearing a body aid, a post-auricular aid (behind-the-ear), or no hearing aid were judged by lay persons and professionals. This study was performed to determine if African American and Caucasian males, judged by female members of their own race, were likely to be judged in a similar manner on the basis of appearance, personality, assertiveness, and achievement. Sixty female undergraduate education majors (30 African American; 30 Caucasian) used a semantic differential scale to rate slides of preteen African American and Caucasian males, with and without hearing aids. The results of this study showed that female African American and Caucasian judges rated males of their respective races differently. The hearing aid effect was predominant among the Caucasian judges across the dimensions of appearance, personality, assertiveness, and achievement. In contrast, the African American judges only exhibited a hearing aid effect on the appearance dimension.
