Programming Time as a Function of Movement Constraint     

Andrew M. Gordon  Robert W. Christina 《Research quarterly for exercise and sport》2013,84(1):92-97

Abstract

Although the benefits of exercise are well documented, an international problem of physical inactivity exists. More research, especially theory based, has been recommended. One promising approach for studying exercise behavior is that proposed in the Transtheoretical Model (TTM) of behavior change. This model, however, has received minimal cross-cultural attention and, relative to the current study, measurement instruments have only recently been translated into the Finnish language. The purpose of this study was to assess American and Finnish college students' exercise behaviors on the basis of TTM. Participants were American (n = 169) and Finnish (n = 168) college students who completed language-specific measures of exercise behavior, stage of change, processes of change, decisional balance, self-efficacy, and temptation. The only cultural difference observed was that the American participants rated themselves higher on barrier self-efficacy relative to the Finnish participants. Regardless of nationality or gender, participants classified by their stage of change differed on all the core constructs assessed. These results generally support the utility of TTM for understanding American and Finnish college students' exercise behavior.  相似文献   

Attention Demands of Precision Pistol-Shooting as a Function of Skill Level     

Debra J. Rose  Robert W. Christina 《Research quarterly for exercise and sport》2013,84(1):111-113

This study provided initial validity evidence for multidimensional measures of coaching competency derived from the Coaching Competency Scale (CCS). Data were collected from intercollegiate men's (n = 8) and women's (n = 13) soccer and women's ice hockey teams (n = 11). The total number of athletes was 585. Within teams, a multidimensional internal model was retained in which motivation, game strategy, technique, and character building comprised the dimensions of coaching competency. Some redundancy among the dimensions was observed. Internal reliabilities ranged from very good to excellent. Practical recommendations for the CCS are given in the Discussion section.  相似文献

A Test of Schmidt's Schema Theory of Discrete Motor Skill Learning     

Julie F. Margolis  Robert W. Christina 《Research quarterly for exercise and sport》2013,84(4):474-483

Abstract

Schmidt's (1975) schema theory was tested with subjects who had to emit a rapid aiming response while wearing prism glasses. The glasses enabled them to view the target, but not their responding limb or the outcome of the movement. The problem was to determine the effect of (a) training with variable target practice, and (b) experiencing visual displacement information of the target, prior to training, on performance in transfer to a novel target distance. A 2 × 2 (type of practice × displacement information) factorial design was used, in which four groups of 15 male college subjects performed 60 training trials with verbal knowledge of results. The groups with variable target practice had less error on initial transfer to the novel target and throughout transfer than the groups with nonvariable target practice. No evidence was found to indicate that rate of learning for a novel target distance during transfer in the absence of KR is a positive function of the variability of target practice in training. Nor was any effect found for experiencing visual displacement information on performance in transfer.  相似文献   

Premotor and Motor Reaction Time As a Function of Response Complexity     

Robert W. Christina  Debra J. Rose 《Research quarterly for exercise and sport》2013,84(4):306-315

Abstract

Two experiments were conducted to identify the response elements responsible for the complexity effect found by Henry and Rogers (1960). An attempt was made to determine if these elements were affecting the premotor time component of simple reaction time (SRT). If they were, a strong case could be made for the argument that neuromotor programming time was affected because premotor time is a more exact estimate of it than SRT. The results revealed that premotor time was unaffected by a forward change in movement direction, but increased as the number of movement parts increased from one to two and as the demand for movement accuracy increased. Thus, increasing the (1) number of parts and (2) accuracy demands were identified as elements of response complexity which increase programming time and support Henry and Rogers (1960) hypothesis that the time to initiate a response becomes longer as the programming process become more complex.  相似文献

Unravelling the gender bind,uncovering the heterogeneity of domination

ABSTRACT

Gender norms and learned practices of student teachers can influence their performance in practice, either fixing or challenging, gendered social norms and expectations. This paper shares the findings of a multi-year mixed-methods research project that explored the understandings of gender norms and experiences of students and staff within a large teacher-training college in Tanzania. Data was collected to inform a wider gender mainstreaming initiative across the institution. Using a blend of quantitative and qualitative methods, the findings identified a strict and rigid gender binary which seemed to inform attitudes and practices of teaching and learning. Furthermore, it uncovered heterogeneous forms of gendered domination that were experienced by staff and pupils within the institution. The findings suggest that stand-alone ‘female only’ gender mainstreaming strategies may not be sufficient to achieve a gender equitable environment within the institution. Rather, it suggests that a whole-of-community approach is necessary to unravel deep-rooted biases and to tackle diverse forms of domination that affect different members of the college community in different ways. Such findings are particularly important in light of the epistemic power that is conferred on teacher-graduates and that is transferred through teaching practices to communities across Tanzania.  相似文献   

The Effects of Training in Social Perspective Taking on Socially Maladjusted Girls   总被引：2，自引：0，他引：2  

Jennifer B. Chalmers  Michael A. R. Townsend 《Child development》1990,61(1):178-190

A paucity of research exists concerning training programs for the development of interpersonal functioning in socially maladjusted or delinquent adolescent females. Females in a residential institution participated in a role-play program designed to enhance social perspective-taking ability. In 15 sessions girls were coached in specific social skills and acted multiple role perspectives in typical problem situations. Compared to girls in a fitness training program, girls in the role-play training program showed enhanced performance on a measure of social perspective taking. Generalized effects were also found for performance on tests of interpersonal problem analysis, empathy, and the acceptance of individual differences. Additionally, observational data indicated that role-play training resulted in increased prosocial behaviors. Role-play training had no effect on a measure of referential communication.  相似文献   

Impacts of an Early Childhood Mathematics and Science Intervention on Teaching Practices and Child Outcomes

abstract

This randomized controlled trial examined effects of the MyTeachingPartner-Math/Science intervention on the quality and quantity of teachers’ mathematics and science instruction, and children’s mathematics and science outcomes in 140 pre-kindergarten classrooms. Teachers participated in the intervention for two years with consecutive cohorts of children. Results from Year 1 are considered experimental, however due to high levels of attrition, results from Year 2 are considered quasi-experimental. Across both years, intervention teachers exhibited higher quality and quantity of instruction. In Year 1, there were no significant effects of the intervention on children’s outcomes. In Year 2, children in intervention classrooms made greater gains in teachers’ ratings of mathematics and science skills and performed better on a spring assessment of science skills. These results have implications for designing and evaluating professional development aimed at supporting children’s mathematics and science knowledge and skills.  相似文献
