Background: Athletic burnout is common when demands of the sport exceed the rewards. Individuals with certain personality dispositions, such as perfectionism, are at increased risk of experiencing perceived stress and subsequent burnout (Fender, L. K. (1989). Athlete burnout: Potential for research and intervention strategies. The Sport Psychologist, 3, 63–71. doi:10.1123/tsp.3.1.63; Gould, D., Tuffey, S., Udry, E., &; Loehr, J. (1996). Burnout in competitive junior tennis players: I. A quantitative psychological assessment. The Sport Psychologist, 10, 322–340. doi:10.1123/tsp.10.4.322; Stoeber, J. (2011). The dual nature of perfectionism in sports: Relationships with emotion, motivation, and performance. International Review of Sport and Exercise Psychology, 4, 128–145. doi:10.1080/1750984x.2011.604789). Perfectionism has both adaptive and maladaptive dimensions, with the more maladaptive qualities leading to greater perceived stress (Hamachek, D. E. (1978). Psychodynamics of normal and neurotic perfectionism. Psychology, 15, 27–33.; Rice, K. G., &; Van Arsdale, A. C. (2010). Perfectionism, perceived stress, drinking to cope, and alcohol-related problems among college students. Journal of Counseling Psychology, 57, 439–450. doi:10.1037/a0020221).Objectives: This study examined the influence of perfectionistic strivings and concerns on burnout, and perceived stress as a mediator of this relationship in Division II and III specialized and multiple-sport athletes (N?=?351).Design: Cross-Sectional.Methods: Participants completed a demographic questionnaire and online measures of perfectionism, stress, and burnout during the latter part of the competitive season.Results: Results showed a positive, direct effect of perfectionistic concerns on burnout. Stress partially mediated this relationship. Additionally, perfectionistic strivings had a negative direct effect on burnout for specialized athletes.Conclusion: The relationship between perfectionistic concerns and burnout is partially explained by stress. Multiple sport athletes showed lower levels of stress compared to specialized ones. Finally, perfectionistic strivings are associated with lower levels of burnout for specialized athletes. 相似文献

Learning progressions have been demarcated by some for science education, or only concerned with levels of sophistication in student thinking as determined by logical analyses of the discipline. We take the stance that learning progressions can be leveraged in mathematics education as a form of curriculum research that advances a linked understanding of students learning over time through careful articulation of a curricular framework and progression, instructional sequence, assessments, and levels of sophistication in student learning. Under this broadened conceptualization, we advance a methodology for developing and validating learning progressions, and advance several design considerations that can guide research concerned with engendering forms of mathematics learning, and curricular and instructional support for that learning. We advance a two-phase methodology of (a) research and development, and (b) testing and revision. Each phase involves iterative cycles of design and experimentation with the aim of developing a validated learning progression. In particular, we gathered empirical data to revise our hypothesized curricular framework and progression and to measure change in students. thinking over time as a means to validate both the effectiveness of our instructional sequence and of the assessments designed to capture learning. We use the context of early algebra to exemplify our approach to learning progressions in mathematics education with a focus on the concept of mathematical equivalence across Grades 3-5. The domain of work on research on learning over time is evolving; our work contributes a broadened role for learning progressions work in mathematics education research and practice. 相似文献

The present study tested real-world racial stereotype use in the context of college athletic recruiting. Stereotype confirmation suggests that observers use stereotypes as hypotheses and interpret relevant evidence in a biased way that confirms their stereotypes. Shifting standards suggest that the evaluative standard to which we hold a target changes as a function of their group membership. We examined whether stereotype confirmation and shifting standards effects would be seen in college football coaches during recruiting. College football coaches evaluated a Black or White player on several attributes and made both zero- and non-zero-sum allocations. Results suggested that coaches used the evidence presented to develop biased subjective evaluations of the players based on race while still maintaining equivalent objective evaluations. Coaches also allocated greater overall resources to the Black recruit than the White recruit. 相似文献

AbstractThis work provides evidence that children as young as six years old successfully leverage written representations to their own purposes. During a modified clinical interview, Maggie created an idiosyncratic written representation to negotiate understanding of the interview task. In this move, Maggie shifted her role in the interview from sharing her own thinking to understanding the interviewer’s thinking. Her representations were not strictly for communication but also for control. This fleeting but illuminating episode points to young children’s intuitive perspective on written representations as a cultural tool. 相似文献

It is shown, with intuitionistic logic, that if every locallyconstant function from to has a property akinto constancy, then the fan theorem for -bars holds, and conversely. 相似文献

This study was designed to evaluate how a series of measures made on 77 infants at ages 3, 6, 9, 12, 18, and 24 months could be used to predict measures made at about 5 years of age. The analytical procedures were selected to be sensitive to differences among individuals in the function that relates test performance to age. Neither evidence for such heterogeneity nor incremental validity of the measures made at 18 months and earlier was obtained. It is concluded that the Gesell Developmental Schedule, the Cattell Infant intelligence Scale, and the California Infant Scale of Motor Development, administered at 18 months and earlier, are invalid both as static indicators of later performance and as dynamic indicators of development. 相似文献
