Abstract

Measurements of the field of motion perception of basketball players and non-basketball players were compared. Also, five basketball skill test items were administered to 101 college men, and their scores on these items and the measurements of the fields of motion perception were compared with subjectively-determined basketball ability rating scores. Measurements of the field of motion perception showed an identifiable relationship with basketball ability and, when combined with basketball test items, made a substantial contribution to the forecasting efficiency of the battery.  相似文献

Abstract

A screening test for lateral dominance was administered to 167 college women. Twenty-six showed left dominance. Of this group four were taught to bowl left-handed, six were eliminated from the study for various reasons and 16 were taught to use their preferred hand, the right. All 20 subjects preferred using their right hand. Both groups were equated as to the amount of practice and motor ability. The group using the presumably dominant left hand were significantly poorer in their bowling average than the group which, though demonstrating left dominance, were permitted to bowl with their preferred hand.  相似文献

Abstract

The ability of 48 college women to adjust hand-eye coordination in a rearranged visual field was compared with ability to learn a new motor skill and with present level of motor ability. The measuring instruments utilized included the Scott motor ability test, Moody's new motor skill learning test, and a variation of the mirror-box test of Held and Gottlieb. Subjects were exposed for one minute to each of four experimental treatments—moving chessmen and throwing a ball performed both while wearing prism-glasses and without wearing these glasses. Subjects received one treatment per day, two days per week; the treatments were repeated in the same order and sequence, making a total of eight experimental sessions. The findings did not justify the conclusion that a relationship exists between motor ability or new motor skill learning and ability to adjust to a rearranged visual field. Wearing prism-glasses did not result in a consistent amount of visual rearrangement with each subject.  相似文献

Abstract

This study was undertaken to compare Negro and white college women in beginning swimming on performance, motor ability, buoyancy, and body measurements. Thirteen Negro and 44 white nonswimmers were assigned to one of four classes for eight weeks of instruction. The criterion of a nonswimmer was the inability to propel the body 15 feet in a prone position with the face immersed. Preliminary tests included the Scott Motor Ability Test and measurements of height, weight, sitting height, leg length, shoulder width, hip width, and breathing capacity. Buoyancy was assessed by hydrostatic weighing. Learning rate was recorded as the number of trials required to execute successfully 15 progressive swimming skills. The Fox Power Test was administered as a measure of terminal achievement. Evidence indicated that the Negro group was significantly superior in motor ability, while the white group was significantly superior in swimming performance and was more buoyant. Because of the difficulty experienced by the Negro group with skills demanding buoyancy, swimming progressions for nonbuoyant college women should not utilize horizontal flotation as an integral component.  相似文献

Abstract

Four test items were devised for each of four motivators: rubber balls, parallel-lines, a red hoop, and a low balance beam. These motivators were designed to serve as stimuli for tests capable of differentiating individual ability to produce both number and uniqueness of motor responses in problem solving tasks of a motor nature. Eight of the test items were administered one day and the remaining eight the following day. Equivalent form reliabilities for items ranged from .59 to .92. Internal coefficient reliabilities were .87 for day I and .92 for day II; however, because of factors such as intrasubject variance only day I data were subjected to a multiple regression analysis to determine the final test battery.

Methods of scoring, such as summing the number of responses (fluency), computing frequency of occurrence (originality), and combining the fluency and originality scores were investigated. Three test forms, each measuring a different aspect of motor creativity, emerged from the analysis. Form O is presented as a measure of motor originality, Form F as a measure of motor fluency, and Form M-C as a measure of motor creativity (motor originality and fluency).

Findings of this study are in agreement with many investigations which find a consistently high relationship between fluency and originality in creativity tests.  相似文献

Abstract

In an attempt to differentiate more adequately between the terms motor ability and athletic participation in their relationship to some measurable aspects of personality, a group of 167 Pomona College junior and senior male students were classified both as to level of motor ability and participation in athletics and were administered the CPI. Utilizing a total test response derived from the sum of ranks of median scores, low and middle motor ability groups ranked higher in the main effects and within the nonathlete and intramural participation groups, but athletic participation did not appear to have any effect upon the measures studied. The pattern of results suggested an expectation hypothesis wherein higher ratings in the personality inventory might be achieved by groups of subjects who participated at a level which would be “expected” in relation to their motor ability.  相似文献

Abstract

The theory proposes a nonconscious mechanism that uses stored information (motor memory) to channel existing nervous impulses from brain waves and general afferent stimuli into the appropriate neuromotor coordination centers, subcenters, and efferent nerves, thus causing the desired movement. A consequent hypothesis requires that the simple reaction time will become longer when the response movement is required to be of greater complexity. Data obtained on college men and women, and 12- and 8-year-old boys, are in agreement with the hypothesis. Replacing a very simple finger movement with an arm movement of moderate complexity slows the reaction by about 20 percent; additional complexity produces a further slowing of 7 percent. The speed of the arm movement is considerably faster in college men than in younger boys or in college women. The correlation between reaction time and speed of movement averages approximately zero. Individual differences in ability to make a fast arm movement are about 70 percent specific to the particular movement being made; “general ability for arm speed” occurs only to the extent of 30 percent.  相似文献

Abstract

Masculinity and femininity ratings were studied in relation to motor performance scores of college women. Arm strength, muscular explosive power, pure speed, and the Humiston Test of motor ability showed a significant positive relationship to andric ratings and a significant negative relationship to gynic ratings. Subjects were classified as being “above”, “at”, or “below” the established mean of the andric and gynic factors. Comparison of mean scores revealed those above the andric mean to be superior on tests of speed, arm strength, and motor ability. Those below the mean of the gynic factor were found to be superior on these same tests and on explosive power. The extent to which the physical expression of masculinity exceeded that of femininity was more highly related to performance scores than were either masculinity or femininity ratings alone.  相似文献

Abstract

This study was conducted for the purpose of determining the relationship between specific factors of personality adjustment and levels of motor achievement in a select group of junior and senior high school boys. Pertinent scales from the 16 Personality Factor Questionnaire and the Guilford Zimmerman Temperament Survey were administered to 154 subjects for the purpose of determining existing personality characteristics. The motor achievement data were collected from administration of the McCloy General Motor Ability and Motor Capacity Test. The data were statistically analyzed through the use of the Pearson product-moment correlation technique, the t test, and the multiple regression technique. The study concluded that, (a) individual group dependance was a factor in extent of exhibited motor achievement and, (b) that levels of motor achievement were predictable with the use of grouped measured personality characteristics.  相似文献

Abstract

Three hundred girls in Georgia ranging from 12 through 18 years of age and enrolled in physical education from the seventh grade through the freshman year in college were given eight motor performance test items to measure running, jumping, throwing, speed, and agility. The study was undertaken to test the hypothesis that girls do not improve in motor performance after the age of 13.5 years, and also to investigate whether significant differences existed in motor skills according to age-grade level. Analysis of variance was used to test the significance of variation on each of the eight test items for the seven age-grade groups. Significance of differences in means for each test for each age-grade group was also calculated. Since ninth-grade girls, with a mean age of 14.4 years, scored highest on two items, tenth-grade girls scored highest on four items, and college girls scored highest on two tests, the hypothesis that girls generally do not evidence improvement in motor skills after the age of 13.5 was rejected.  相似文献

Abstract

The purpose of this investigation was to study the effect of swimming on the learning and performance of two complex gross motor skills. Forty college men were matched on the basis of a pre-test and formed into experimental and control groups. The experimental group learned the two selected skills in addition to swimming, whereas the control group learned only the selected skills. Two scoring systems were used, and findings indicated no significant difference between groups.  相似文献

Purpose: This exploratory study examined the notion of Seefeldt's (1980) hypothesized motor skill “proficiency barrier” related to composite levels of health-related physical fitness (HRF) in young adults. Method: A motor skill competence (MSC) index composed of maximum throwing and kicking speed and jumping distance in 187 young adults aged 18 to 25 years old was evaluated against a composite index of 5 health-related fitness (HRF) test scores. MSC (high, moderate, and low) and HRF indexes (good, fair, and poor) were categorized according to normative fitness percentile ranges. 2 separate 3-way chi-square analyses were conducted to determine the probabilities of skill predicting fitness and fitness predicting skill. Results: Most correlations among HRF and MSC variables by gender demonstrated low-to-moderate positive correlations in both men (12/15; r = .23–.58) and women (14/15; r = .21–.53). Chi-square analyses for the total sample, using composite indexes, demonstrated statistically significant predictive models, χ 2 (1, N = 187) = 66.99, p < .001, Cramer's V = .42. Only 3.1% of low-skilled (2 of 65) individuals were classified as having a “good” HRF. Only 1 participant (out of 65) who demonstrated high MSC was classified as having “poor” HRF (1.5%). Conclusion: Although individual correlations among individual MSC and HRF measures were low to moderate, these data provide indirect evidence for the possibility of a motor skill “proficiency barrier” as indicated by low composite HRF levels. This study may generate future research to address the proficiency barrier hypothesis in youth as well as adults.  相似文献

Abstract

Eighty-two male college students were divided into three equal-size groups for the purpose of testing the transfer effects between motor skills judged similar in perceptual components but different in motor components.

Criterion measures of gross movement ability and static balance were analyzed and practice tasks similar to these criterion measures in perceptual components but different in motor components were developed. All subjects were pretested on the criterion measures, after which groups 1 and 2 practiced 3 min. per day for 28 days on the practice tasks while group 3 performed unrelated isometric exercises. On the post-test, the experimental groups were found to be significantly superior to the control group on gross movement accuracy and static balance. It was implied that the transfer resulted from the similarity in perceptual components of the two motor skills, and that perceptual abilities were subject to improvement through practice.  相似文献

Abstract

One hundred and seven college women were tested in their ability to recognize a demonstrated body posture from among similar ones and to reproduce demonstrated body postures. Two original tests were devised for this purpose. A low but statistically significant correlation (- .34) was found between the two. In addition, the subjects completed a questionnaire regarding the extent and nature of their motor experience. The extent of the individual's motor experience had a significant role in each of these abilities. The direction to be taken in reproducing the postures was found to be a complicating factor.  相似文献

Abstract

Forearm flexion strength of 65 college men was measured at two distances from the elbow at each of three angles of the forearm. The speed of forearm flexion movement was measured through an arc of 85°. Ebel intraclass reliabilities for strength and speed were high, i.e., .95 to .99. The extremely low correlations between limb strength and speed of movement, which ranged from —.06 to .14, are in agreement with the majority of the low correlations reported in earlier studies. The findings of this study support the theory of specificity in that individual differences in the speed of a limb involving a single joint are predominantly independent of strength measures associated with that limb and joint.  相似文献

Abstract

The present study investigated the relationship between two of the most common measures of motor imagery ability, self-report ratings, and chronometric assessment. This was done for three types of imagery modalities: external visual imagery (EVI), internal visual imagery (IVI), and kinesthetic imagery (KI). Measures of imagery ability (i.e. self-report and mental chronometry) were also compared across skill levels. Participants (N?=?198) completed the Movement Imagery Questionnaire-3 (MIQ-3) to generate self-report ratings. Chronometric assessment was obtained by recording the duration of each MIQ-3 movement imaged and physically performed and then calculating a discrepancy score. There were no significant correlations between self-report and mental chronometry for any of the three motor imagery types (p?>?.05). When assessing the different types of motor imagery ability using self-report ratings, elite athletes had significantly higher KI than IVI, which was in turn significantly higher than EVI (p?<?.05). When assessing motor imagery ability using mental chronometry, there were no significant differences in imagery type (p?>?.05). Findings suggest both measures address different components of MI quality and should be used together to obtain a more comprehensive assessment of motor imagery ability.  相似文献

Abstract

The study was designed to determine the relationships between achievement in reading and achievement in selected motor skills for children in grades 1, 3, 5. The Iowa tests of basic skills were used to determine reading achievement and the Johnson motor achievement battery was employed to measure achievement in selected motor skills. The Pearson product-moment coefficient of correlation was applied to compute the relationships between the reading and motor achievement variables. The subjects were divided into three reading achievement levels and Scheffe's method of comparing pairs of means from a two-way analysis of variance table was employed to determine if the achievement differences in the motor skills tests were significant. The following conclusions were drawn: a) Highly significant correlations were found to exist between achievement in reading and the throw and catch test and achievement in reading and the zig-zag run test; b) Little or no consistent relationship existed between achievement in reading and the kicking test or the jump and reach test; c) Significant differences among the selected reading levels were found for the throw and catch test and the zig-zag run test; d) Few significant differences among the selected reading levels were found for the kicking test and for the jump and reach test.  相似文献

Abstract

Sixteen college men were randomly divided into three training groups and one control group in a study of selected cardiorespiratory adaptations to six weeks of training exercises eliciting either 120, 150, or 180 heart rates. Training consisted of walking on the motor driven treadmill for 10 min. a day, 3 days per week. Highly significant differences were found in the analysis of pre-post Balke treadmill test scores. The Åstrand-Ryhming nomogram prediction of aerobic capacity also showed highly significant changes due to training. Analysis of group differences revealed that the 180 training group's improvement was significantly different from all other groups in both tests. The 150 group was found to be significantly different from the 120 and control groups in the Balke test analysis. No changes were noted in resting pulse rate nor in the pulse rate—oxygen consumption relationship. However, there were small positive differences in the grade required to elicit the training heart rates. The study supports the hypothesis that intense activity is necessary to bring about the changes associated with cardiorespiratory endurance.  相似文献

Abstract

Sixty college men were tested on a new motor learning task: the foot-twist tracking task. They were given 35 one-min. trials; each consisted of 30 sec. of work followed by 30 sec. of rest. A 5-min. rest period was interpolated between trials 25 and 26 to allow for the dissipation of reactive inhibition accrued during prerest performance. The results supported the expectation that practice on the new task would result in significant amounts of learning. However, the improvement in performance, while fairly large (21%), is substantially less than that found on the pursuit rotor and other large muscle motor coordination tasks. The expectation of reliable learning scores is also supported by the present results (r = .77). This learning reliability is relatively high when compared with those obtained on other large muscle motor learning tasks.  相似文献

Abstract

Thirty-six male college students were measured in six cardiovascular factors as recorded by the Cameron Heartometer. Seventeen of these subjects were smokers and 19 were non-smokers. The purpose of this investigation was to find what residual, as opposed to acute, effects, smoking has on young men. Each subject in both groups was measured in six cardiovascular factors, nine times successively, during his testing period. The smokers abstained from smoking on the day of testing.

The residual effects of smoking in young men, if there be any, cannot be demonstrated in a statistically significant manner in certain cardiovascular factor measurements in the quiet state.  相似文献
