ObjectivesThe present study examined the effects of motivational self-talk on self-confidence, anxiety, and task performance in young athletes.MethodsParticipants were 72 tennis players. The experiment was conducted in five sessions: baseline assessment, three training sessions, and final assessment. After the baseline assessment participants were divided and assigned randomly into experimental and control groups. The two groups followed the same training program with the experimental group practicing the use of self-talk. In the last session, the final assessment took place. A forehand drive test was used to evaluate task performance, and the Competitive Anxiety Inventory-2R was used to assess self-confidence and anxiety.ResultsA two-way mixed model MANOVA revealed that task performance improved for the experimental group (p < .01) and remained stable for the control group; self-confidence increased (p < .01) and cognitive anxiety decreased (p < .05) for the experimental group, whereas no changes were observed for the control group. Correlation analysis revealed that changes in task performance were moderately related to changes in self-confidence (p < .05).ConclusionsThe results of the study showed that self-talk can enhance self-confidence and reduce cognitive anxiety. Furthermore, it is suggested that increases in self-confidence can be regarded as a viable function explaining the facilitating effects of self-talk on performance. 相似文献

ObjectivesThe aim of this article is to outline how certain key assumptions affect the quality and interpretation of research in quantitative sport and exercise psychology.MethodsA review of three common assumptions made in the sport and exercise psychology literature was conducted. The review focused on three assumptions relating to research validity and the treatment and interpretation of observations. A central theme to this discussion is the assumption that research observations reflect true effects in a population.ResultsAssumptions often made in sport and exercise psychology research were identified in three key areas: (1) validity, (2) inferences of causality, and (3) effect size and the “practical significance” of research findings. Findings indicated that many studies made assumptions about the validity of the self-report psychological measures adopted and few provided a comprehensive evaluation of the validity of these measures. Researchers adopting correlational designs in sport and exercise psychology often infer causality despite such conclusions being based on theory or speculation rather than empirical evidence. Research reports still do not include effect size statistics as standard and confine the discussion of findings to statistical significance alone rather than commenting on “practical significance”.ConclusionResearch quality can only be evaluated with due consideration of the common assumptions that limits empirical investigation in sport and exercise psychology. We offer some practical advice for researchers, reviewers, and journal editors to minimise the impact of these assumptions and enhance the quality of research findings in sport and exercise psychology. 相似文献

This paper presents the results of a study of the effects of left hemisphere strokes on syntactically-based comprehension in aphasic patients. We studied 42 patients with aphasia secondary to left hemisphere strokes and 25 control subjects for the ability to assign and interpret three syntactic structures (passives, object extracted relative clauses, and reflexive pronouns) in enactment, sentence-picture matching and grammaticality judgment tasks. We measured accuracy, RT and self-paced listening times in SPM and GJ. We obtained magnetic resonance (MR) and 5-deoxyglucose positron emission tomography (FDG PET) data on 31 patients and 12 controls. The percent of selected regions of interest (ROIs) that was lesioned on MR and the mean normalized PET counts per voxel in ROIs were calculated. In regression analyses, lesion measures in both perisylvian and non-perisylvian ROIs predicted performance. Patients who performed at similar levels behaviorally had lesions of very different sizes, and patients with equivalent lesion sizes varied greatly in their level of performance. The data are consistent with a model in which the neural tissue that is responsible for the operations underlying sentence comprehension and syntactic processing is localized in different neural regions in different individuals. 相似文献

The Museum of Old and New Art (MONA), in Australia's island state of Tasmania, bears all the hallmarks of the new museology and a flagship museum. Located in a largely working class area, there are expectations of visitors from diverse socioeconomic backgrounds, particularly local residents. However most visitors are tourists, middle-class, and highly educated. In this article, the authors ask, “What are the issues affecting accessibility to MONA for local residents?” In asking this, they aim to better understand local engagement with MONA and shed light on potential socio-cultural transformation. Using a survey, interviews, and focus groups with local residents, the authors found that accessibility at MONA is defined along familiar socioeconomic lines, though there are indications of change that warrant further investigation. The expense of food and beverage, concern about children's behavior, and the explicit nature of some art all impact on accessibility, particularly for those with less cultural capital. 相似文献

This study examined what Greek adolescents believe are the most important criteria of personal, boys', and girls' popularity in their age group. Participants were 364 students aged between 12 and 15 years. Seven main criteria of popularity were identified: sport competence, physical appearance, academic ability, being a good friend, being sociable, having a good sense of humor, and having the 'right circle of friends'. With regard to personal popularity, being a good friend and being sociable were the two most highly ranked criteria for both boys and girls across all ages. Boys and girls perceived differently the most important criteria of boys' and girls' popularity. Specifically, for same-sex popularity, being a good friend was the most highly ranked criterion, whereas for other-sex popularity, physical attractiveness was the most highly ranked criterion. The findings imply that friendship and social affiliation are the most important criteria of popularity in Greek adolescents. 相似文献

Dimensions of Coaching Behavior, Need Satisfaction, and the Psychological and Physical Welfare of Young Athletes 总被引:1,自引:0,他引:1
Grounded in self-determination theory (E. L. Deci & R. M. Ryan, 2000), the purpose of this study was to examine the relationship of dimensions of coaching behavior to intrinsic need satisfaction and indices of psychological and physical well-being among male adolescent athletes. Participants were 265 British soccer and cricket players (M
age = 16.44). Structural equation modeling analysis, using maximum likelihood robust method, showed athletes' perceptions of autonomy support, mastery focus, and social support from the coach to predict their satisfaction of the needs for autonomy, competence, and relatedness, respectively. The satisfaction of the need for competence emerged as the most important predictor of psychological and physical well-being. The findings suggest that particular aspects of the social environment may be salient for fostering particular psychological needs. The results also underline the importance of perceived competence for the psychological and physical welfare of adolescents in team sports. 相似文献

Delayed adjustment tasks have recently been developed to examine working memory (WM) precision, that is, the resolution with which items maintained in memory are recalled. However, despite their emerging use in experimental studies of healthy people, evaluation of patient populations is sparse. We first investigated the validity of adjustment tasks, comparing precision with classical span measures of memory across the lifespan in 114 people. Second, we asked whether precision measures can potentially provide a more sensitive measure of WM than traditional span measures. Specifically, we tested this hypothesis examining WM in a group with early, untreated Parkinson's disease (PD) and its modulation by subsequent treatment on dopaminergic medication. Span measures correlated with precision across the lifespan: in children, young, and elderly participants. However, they failed to detect changes in WM in PD patients, either pre‐ or post‐treatment initiation. By contrast, recall precision was sensitive enough to pick up such changes. PD patients pre‐medication were significantly impaired compared to controls, but improved significantly after 3 months of being established on dopaminergic medication. These findings suggest that precision methods might provide a sensitive means to investigate WM and its modulation by interventions in clinical populations. 相似文献

No prior research has examined how motivation for goal striving influences persistence in the face of increasing goal difficulty. This research examined the role of self‐reported (Study 1) and primed (Study 2) autonomous and controlled motives in predicting objectively assessed persistence during the pursuit of an increasingly difficult goal. In Study 1, 100 British athletes (64 males; Mage = 19.89 years, SDage = 2.43) pursued a goal of increasing difficulty on a cycle ergometer. In Study 2, 90 British athletes (43 males; Mage = 19.63 years, SDage = 1.14) engaged in the same task, but their motivation was primed by asking them to observe a video of an actor describing her or his involvement in an unrelated study. In Study 1, self‐reported autonomous goal motives predicted goal persistence via challenge appraisals and task‐based coping. In contrast, controlled goal motives predicted threat appraisals and disengagement coping, which, in turn, was a negative predictor of persistence. In Study 2, primed autonomous (compared to controlled) goal motives predicted greater persistence, positive affect, and future interest for task engagement. The findings underscore the importance of autonomous motivation for behavioral investment in the face of increased goal difficulty. 相似文献

The study examined the effects of a motivational self-talk intervention on endurance cycling performance in hot conditions. Participants were 16 physically active adult men. After a baseline VO2 peak assessment and two training sessions, participants completed a 30 min cycling trial in a hot environment (35°C, 45% relative humidity) while maintaining a steady rate of perceived exertion. Participants of the intervention group produced greater power output during the final third of the trial. Findings suggest that the self-talk strategy seems to have compromised the aversive effects of the demanding environmental conditions and provide support for the psychobiological model of endurance performance. 相似文献
