Abstract

Items from the Reinvestment Scale were modified to create a decision-specific version of the scale. Principal components analysis of responses from 165 participants revealed one-, two-, three-, and four-factor solutions for the Decision-Specific Reinvestment Scale. Confirmatory factor analysis of responses from a second sample of 111 participants revealed that a 13-item two-factor solution showed the best fit. The first factor comprised six items referring to conscious monitoring of the process involved in making a decision, and was termed decision reinvestment. The second factor, decision rumination, comprised seven items related to focus on negative evaluations of previous poor decisions. In an initial assessment of predictive validity, Decision-Specific Reinvestment Scale scores of 59 skilled team sport players were found to be highly correlated with coaches' ratings of players' tendency to choke under pressure (r = 0.74), with high Decision-Specific Reinvestment Scale scores indicating greater susceptibility to poor decision-making under pressure. It was concluded that the Decision-Specific Reinvestment Scale highlights a performer's predisposition to engage in behaviours detrimental to performance under pressure, namely decision reinvestment and decision rumination.  相似文献

This study was grounded in the belief systems and physical activity literature and investigated preservice teachers' belief systems toward curricular outcomes for physical education programs. Preservice teachers (N = 486; men = 62%, women = 38%) from 18 U.S. colleges/universities shared their beliefs about curricular outcomes. Preservice teachers completed a previously validated belief systems instrument designed to measure the relative importance of four outcome goals for programs (physical activity/fitness, self-actualization, motor skill development, and social development). Internal consistency reliability for the instrument was .98. A confirmatory factor analysis demonstrated a good fit of the current sample to the hypothesized outcomes model. Multivariate analysis of variance results revealed a significant interaction in outcome preservice teachers' priorities for year in school by region. The teachers' views also differed on the important outcome goals for physical education. Two critical “tensions” are discussed: (a) the need to examine more fully the consistency of preservice teacher/teacher belief systems, and (b) implications for teacher education and professional development programming. It is important to heed prospective teachers' voices and address their belief systems in teacher education programs.  相似文献

Abstract

This study was designed to investigate the effect of an interactive videodisc motor skill assessment training program on the development of preservice and inservice teachers' qualitative assessment proficiency on two motor skills: the overhand throw and catch. Twenty-seven preservice and 27 inservice physical education teachers were randomly assigned to one of three treatment conditions: interactive videodisc (IVD), teacher-directed (TD), or self-directed (SD). Motor skill qualitative assessment accuracy was evaluated on a pre- and post-test basis using a 50-item motor skill assessment accuracy test (10 performances rated on 5 components) for each skill. Analysis of covariance results indicated significant main effects for treatment for both skills. Post hoc tests revealed that for the over hand throw, the IVD and TD groups were superior to the SD group but not different from each other. For the catch, the IVD group was found to be superior to both the TD and SD groups. These findings are discussed in relation to the advantages of interactive videodisc in terms of efficiency and user independence and with comparable findings in other educational applications.  相似文献

Abstract

Based upon predictions derived from the Developmental Model of Sports Participation, we tested whether hours in domain-specific play (self-led activities) and practice (coach-led activities) during childhood (~5–12 year) in an elite group of youth soccer players from the UK (N = 144) were related to motivation. Independent analysis of three different age groups (Under 13, 15 and 17 year) did not show relations between play and practice activities during childhood and global measures of motivation. However, secondary analysis showed that when controlling for years in soccer, years in the UK Academy system were negatively related to global indices of self-determined motivation (SDI) and positively related to controlled motivation for the oldest players. Despite predictions, there was no evidence that play during childhood was positively related to more SDI. Prospective research is recommended to enable more robust conclusions about the role of early developmental practice activities, especially early specialisation in a high-performance system, on both skill and psychosocial development.  相似文献

Abstract

Attitudes, creativity, self-concept and motor skills were measured to determine the influence of decision-making on elementary children. Three groups of children (N = 208) were tested, one group was taught with the teacher dominating all classroom decisions, another group was encouraged to share in the decision-making, and a third group served as a control. Data were collected immediately before and after an eight-week instructional period. MANCOVA indicated that the two treatment groups had significantly higher scores than did the control group, and the shared decision-making group scored significantly higher than the teacher dominated group on measures of creativity, motor skills and self-concept. A 2 (treatment) × 2 (sex) × 5 (grade) ANOVA revealed significantly more positive attitude scores for children allowed to make decisions regarding their learning. Further, Pearson product-moment correlation showed the tested variables to be independent measures of a child's development.  相似文献

Abstract

In order to investigate how children remember distance (route) and location (landmark) information, two experiments were conducted in a large scale environment using jogging as the means of locomotion. In Experiment 1, thirty 4-year-old and thirty 9-year-old children were randomly assigned within age to three groups which were cued prior to the jog to remember the event, location of the event or distance to the event. Results indicated that older children reproduced the location and distance better than younger children. Cueing children to remember the location resulted in more accurate estimates than the other conditions. In Experiment 2, 5-year-old, 9-year-old, and 12-year-old children (24 children of each age) were randomly divided into step counting strategy and control groups, and asked to reproduce a criterion distance jogged. Results indicated that the three strategy groups and the 12-year-old controls estimated distance with similar accuracy, but the 9- and 5-year-old controls were different, as their error was inversely related to age.  相似文献

Abstract

The primary purpose of this study was to assess perceived and experienced role conflict of high school female athletes in enacting the roles of female and female athlete. Data were collected on 133 high school varsity athletes by the use of a 33-item questionnaire designed to assess perceived and experienced role conflicts of the subjects, their socioeconomic backgrounds, and specific instances of encouragement or discouragement from significant others experienced during their athletic careers. Thirty-two percent of the subjects responded that they perceived little or no problem with role conflict, and 50% had experienced little or no role conflict. Seventeen percent of the subjects responded that they perceived role conflict to be a great or very great problem with 11% experiencing role conflict to the same degree. A chi square analysis of perceived and experienced role conflict computed for the entire group of subjects indicated that the athletes perceived greater role conflict than they had experienced (p<.01). A one way analysis of variance was performed comparing the means of the athletes in traditionally socially approved sports, those in non-traditionally socially approved sports, and those participating in both categories. Results indicated a tendency for those participating simultaneously in both socially approved and non-socially approved sports to have experienced more role conflict (p≤.07).

A distinction between internal and external role conflict was suggested as a method of understanding the different types of pressures with which the female athlete must deal.  相似文献

Abstract

This study investigated the effects of iron supplementation (18 mg per day) on the serum iron, total iron binding capacity (TIBC), hemoglobin levels, and percent hemoglobin saturation with iron of female college basketball athletes. The serum iron and hemoglobin levels of ten varsity basketball athletes and seven control subjects (nonathletes) were measured (pretest) prior to the basketball season and again at the end of the season. Iron supplements, no supplements, or a placebo tablet were given during the 4-month experimental period. ANOVA statistical analyses revealed that the iron supplementation was of no value in raising serum iron, TIBC, percent saturation, and hemoglobin levels and that a 4-month basketball training regimen and season did not significantly lower serum iron and hemoglobin levels.  相似文献
