基于“习得无助”理论的“动机缺乏模式”和“功能缺乏模式”发展一个体育竞赛的努力缺乏综合模式，通过实验设计验证6个理论假设。80名体育专业学生参加一个投篮对抗，决定胜负，然后，再参加一个投掷飞镖的任务。对被试的朝向认知活动、后续朝向状态、后续努力与第二任务成绩的关系进行分析。结果发现，失败的被试比成功被试更关注结果引起的原因，同时，对后续控制感更低；当归因倾向非控制因素时，后续努力变得下降。另外，归因的方式对后续努力和投标成绩都有影响。  相似文献

Abstract

This study determined the effectiveness of a global learning strategy on the skill level attained in one closed primary task and two related ones. Eighty subjects were randomly assigned to five groups equal in number and sex: a content-dependent strategy group (CDS), a content-dependent strategy plus reminders group (CDSR), a content-independent strategy group (CIS), a content-independent strategy plus reminders group (CISR), or a control group. A content dependent strategy is one learned in reference to a specific task; in this case, the primary one. A content independent strategy is learned in the context of many example tasks. Subjects performed underhanded dart throwing as the primary task, jart throwing (similar in nature to dart throwing) as the directly related task, and soccer foul shooting as the slightly related task. The strategy used to test the hypotheses generated was the Singer 5-Step Strategy. ANOVAs indicated that all of the strategy learning conditions were significantly more effective than the control condition for each task. Furthermore, the CIS learning situation was more beneficial for the learning of the task most related to the primary task than the CDS learning situation. The CISR group outperformed the other strategy groups in the less-related task.  相似文献

The aim of this paper is to outline the development of Eysenck and Calvo's (1992) processing efficiency theory (PET) and to summarise research testing its predictions in the sporting domain. PET provides a mechanistic explanation for how anxiety may influence performance through its impact on attentional resources. The central tenet of PET is that as well as pre-empting resources in working memory, increased anxiety provides a motivational function, leading to the allocation of additional effort to attempt to maintain task performance. Research in sport settings has been supportive of the predictions of PET, adopting a range of measures of processing efficiency; including self-reported effort, secondary task performance and psychophysiological indices. Furthermore, cognitive sport psychologists have recently examined direct influences of anxiety on the efficiency of information processing via gaze behaviour analyses. These findings are particularly relevant in the light of a recent update and development of PET; attentional control theory (ACT; Eysenck, Derakshan, Santos, & Calvo, 2007). ACT purports that anxiety reduces attentional control by increasing the influence of the stimulus-driven attentional system at the cost of goal directed control. It is evident that ACT may provide a useful framework for examining the relationship between anxiety, attention and performance in sport skills.  相似文献

In this study, we examined attention processes in complex, sport-specific decision-making tasks without interdependencies from anticipation. Psychophysiological and performance data recorded from advanced and intermediate level basketball referees were compared. Event-related potentials obtained while judging game situations in foul recognition and a control task provided insight into focus of attention, selective attention, and processing strategy (top-down vs. bottom-up). Results showed task-specific effects for advanced referees in components influenced by attentional focus and selective attention. Experts also seemed to profit from superior top-down strategy and were able to evaluate the stimuli more rapidly. These findings are discussed in connection with current models in neurosciences and theories of referee research.  相似文献

“自我批判”指个体为了保护自尊而朝向规避负面可能性结果的心理倾向,反映了个体高标准的“自我关注”。运用飞镖任务的“Choking”实验范式,把“自我批判”作为内源性中介变量,观察其在压力下运动表现的作用解释机制。对50名大学生运动员进行“自我批判”的人格测试,并分别在无压力和压力条件下完成飞镖投掷任务的测试,所得数据通过SPSS 24.0和Process 3.0进行统计分析。研究发现,“自我批判”倾向的被试在压力条件下表现了“自我关注”的认知压力(β=0.50,P<0.001);同时,其“Choking”表现也随之增加(β=0.35,P<0.01)。因此,“自我批判”作为“Choking”的内源性诱因,具有部分的中介作用机制解释,其解释变异的效应占25%。  相似文献

竞赛焦虑对操作表现的影响是运动心理学的重要研究领域,注意控制理论对二者关系从执行功能的角度进行了新的阐释,认为焦虑干扰执 行功能中的抑制功能。近年来,运动心理学对抑制功能探讨较多,对优势反应和任务无关刺激的抑制是抑制功能的2个重要成分,但以往研究大多 集中于抑制无关刺激,对优势反应抑制的探讨相对欠缺,而后者却是竞技场上运动员时常需要面对的问题。已有行为学研究发现,竞赛特质焦虑对 优势反应抑制功能有干扰效应,但其神经机理尚待探讨。本研究采用ERP技术探讨竞赛特质焦虑干扰优势反应抑制的神经基础,假设竞赛特质焦 虑干扰前脑区域（额区和中央区）优势反应抑制的神经准备过程。招募26名研究参与者,根据《赛前情绪量表32×6》测试得分,二分法划分竞赛特质 焦虑高分组和低分组。2组均完成代表优势反应抑制功能的反向眼跳任务,分析抑制“线索”出现前-100~0 ms时程的ERP成分,发现反向眼跳的准 备期在额区和中央区诱发出一负成分,竞赛特质焦虑高分组的波幅小于低分组。以上结果部分支持了假设,竞赛特质焦虑对优势反应抑制的神经 准备期有干扰效应,且主要由前脑区域控制,此结果为注意控制理论在竞赛焦虑领域的适用性提供了神经生理学的部分证据。  相似文献

In this study, we examined how individuals controlled their gaze behaviour during execution of a far aiming task and whether the functional relationship between perception and action was disrupted by increased anxiety. Twenty participants were trained on a simulated archery task, using a joystick to aim and shoot arrows at the target, and then competed in two counterbalanced experimental conditions designed to manipulate the anxiety they experienced. The specific gaze behaviour measured was the duration of the quiet eye period. As predicted, accuracy was affected by the duration of the quiet eye period, with longer quiet eye periods being associated with better performance. The manipulation of anxiety resulted in reductions in the duration of quiet eye. Our results show that the quiet eye period is sensitive to increases in anxiety and may be a useful index of the efficiency of visual orientation in aiming tasks.  相似文献

Achieving a state of flow is associated with positive experiences and improved sporting performance (Jackson &; Csikszentmihalyi, 1999). Focused attention is a fundamental component of the flow experience, but to date there has been little investigation of whether attention plays a causal role in creating flow, or is a product of it. Consequently, this study aimed to test the effect of an attentional focus manipulation on flow and performance in a simulated driving task. It was predicted that an external focus would lead to improved visuomotor control, greater flow experience and improved performance. Thirty-three participants from a student population completed the driving task under both internal and external focus instructions. Eye movements and steering wheel movements were recorded during each race. Participants reported greater flow experience (p?d?=?1.78) and enhanced outcome expectancies (p?=?.02, d?=?0.41) under external, compared to internal focus conditions, however, there was no effect on visuomotor control (gaze-steering coordination and steering entropy) or racing performance (ps?>?0.28). These findings suggest that adopting an external focus of attention may contribute to positive performance states such as flow.  相似文献

The role of focusing attention on one limb or both limbs in a bimanual aiming task was investigated in two experiments. Participants were prompted to focus attention on either limb (Experiment 1) or were free to choose their attentional strategy (Experiment 2). Fifty-two college-aged participants made quick, bimanual lever reversals in the sagittal plane over 20 degrees and 60 degrees in 210 ms to the reversal point. In both experiments, spatial accuracy was better when participants focused their attention on a single limb compared to the nonattended limb and when they paid attention to both limbs. However, no differences were shown on a no-knowledge of results (KR) retention test when participants paid attention to both limbs. In the second experiment, differences were maintained on a no-KR retention test when participants continued to select their own attentional strategy, although the statistical effect was smaller than in the first experiment. The findings suggested that the movement parameter selection process benefited from attentional focus.  相似文献

Whereas numerous studies have confirmed the objectivity and reliability of the “ Allgemeine Sportmotorische Test für Kinder” (AST, a general motor fitness and coordination test for children), examinations of its construct validity reveal that: (1) the few available findings fail to confirm the theoretically predicted distinction between the latent variables of condition and coordination, and (2) no studies so far have examined its item homogeneity, even though the test recommends computing a sum score to provide a general estimate of motor fitness. Confirmatory factor analyses show that the two latent variables condition and coordination cannot be extracted from the AST. Models with different latent variables also cannot be confirmed, too. Analyses based on IRT models, in contrast, reveal that one can distinguish between two qualitative classes of persons who are associated with either better running performance combined with lower throwing performance or better throwing performance combined with lower running performance. Nonetheless, it should be noted that class membership does not remain constant over time. In sum, results based on classical and probabilistic test theory negate the ability assumption underlying the AST. For practical assessments of a skill-specific performance, this means that it only seems justifiable to use a sum score for the locomotion items and a sum score for the object manipulation items.  相似文献

We tested some of the key predictions of processing efficiency theory using a simulated rally driving task. Two groups of participants were classified as either dispositionally high or low anxious based on trait anxiety scores and trained on a simulated driving task. Participants then raced individually on two similar courses under counterbalanced experimental conditions designed to manipulate the level of anxiety experienced. The effort exerted on the driving tasks was assessed though self-report (RSME), psychophysiological measures (pupil dilation) and visual gaze data. Efficiency was measured in terms of efficiency of visual processing (search rate) and driving control (variability of wheel and accelerator pedal) indices. Driving performance was measured as the time taken to complete the course. As predicted, increased anxiety had a negative effect on processing efficiency as indexed by the self-report, pupillary response and variability of gaze data. Predicted differences due to dispositional levels of anxiety were also found in the driving control and effort data. Although both groups of drivers performed worse under the threatening condition, the performance of the high trait anxious individuals was affected to a greater extent by the anxiety manipulation than the performance of the low trait anxious drivers. The findings suggest that processing efficiency theory holds promise as a theoretical framework for examining the relationship between anxiety and performance in sport.  相似文献

The game of darts attracts a large international following and can be fiercely competitive. Despite its popularity, and the large equipment market, no previous peer-reviewed studies have examined the trajectory of a dart in flight. This study used high-speed video techniques to measure the trajectories of 225 dart throws from 19 amateur players. The dart’s pitch and angle of attack were found to oscillate during flight in a manner that is analogous to damped harmonic motion. It was also found that the dart’s oscillation frequency was strongly correlated to launch speed, whilst its characteristic wavelength and damping ratio were independent of launch speed. The measured wavelength of oscillation (2.16 m) was found to be similar to the regulation throwing distance (2.37 m). It is proposed that the dart is ‘tuned’ to the throwing distance such that it undergoes one full oscillation before striking the board. The dart flight was modelled using a classical dynamic stability analysis and good agreement was found between the experimental observations and the theoretical predictions. The success of the model confirms that the approach can be used to explore the dynamics of different dart designs through parametric sensitivity analyses.  相似文献

This study examined attentional processes underlying skilled motor performance in threatening situations. Twenty-four trained participants performed a simulated rally driving task under conditions designed either to direct the focus of attention toward the explicit monitoring of driving or a distracting secondary task. Performance (lap time) was compared with a "driving only" control condition. Each condition was completed under nonevaluative and evaluative instructional sets designed to manipulate anxiety. Mental effort was indexed by self-report and dual-task performance measures. The results showed little change in performance in the high-threat explicit monitoring task condition, compared with either the low-threat or the high-threat distraction conditions. Mental effort increased, however, in all high- as opposed to low-threat conditions. Performance effectiveness was therefore maintained under threat although this was at the expense of reduced processing efficiency. The results provide stronger support for the predictions of processing efficiency theory than self-focus theories of choking.  相似文献

This study investigated the visual attention of older expert orienteers and older adults not practicing activities with high attentional and psychomotor demands, and considered whether prolonged practice of orienteering may counteract the age-related deterioration of visual attentional performance both at rest and under acute exercise. In two discriminative reaction time experiments, performed both at rest and under submaximal physical workload, visual attention was cued by means of spatial cues of different sizes followed, at different stimulus-onset asynchronies, by compound stimuli with local and global target features. Orienteers, as compared to nonathletes, showed a faster reaction speed and a complex pattern of attentional differences depending on the time constraints of the attentional task, the demands on endogenous attentional control, and the presence or absence of a concomitant effortful motor task. Results suggest that older expert orienteers have developed attentional skills that outweigh, at least at rest, the age-related deficits of visual attentional focusing.  相似文献

We assessed the extent to which failures in sustained attention were associated with chronic mild traumatic brain injury (mTBI) deficits in cognitive control among college-age young adults with and without a history of sport-related concussion. Participants completed the ImPACT computer-based assessment and a modified flanker task. Results indicated that a history of mTBI, relative to healthy controls, was associated with inferior overall flanker task performance with a greater number of omission errors and more frequent sequentially occurring omission errors. Accordingly, these findings suggest that failures in the ability to maintain attentional vigilance may, in part, underlie mTBI-related cognition deficits.  相似文献

The purpose of this study was to examine the central tenets of the processing efficiency theory using psychophysiological measures of attention and effort. Twenty-eight participants were divided equally into either a high or low trait anxiety group. They were then required to perform a simulated driving task while responding to one of four target light-emitting diodes. Cortical activity and dual task performance were recorded under two conditions -- baseline and competition -- with cognitive anxiety being elevated in the competitive session by an instructional set. Although driving speed was similar across sessions, a reduction in P3 amplitude to cue onset in the light detection task occurred for both groups during the competitive session, suggesting a reduction in processing efficiency as participants became more state anxious. Our findings provide more comprehensive and mechanistic evidence for processing efficiency theory, and confirm that increases in cognitive anxiety can result in a reduction of processing efficiency with little change in performance effectiveness.  相似文献

This research examined attentional bias toward exercise-related images using a visual probe task. It was hypothesized that more-active participants would display attentional bias toward the exercise-related images. The results showed that men displayed attentional bias for the exercise images. There was a significant interaction of activity level by gender, and simple slopes analysis showed that active women displayed attentional bias toward the exercise-related images and inactive women displayed attentional bias toward the control images. A similar analysis with explicit attention to the pictures as the outcome variable was not significant. These findings confirm that attention for exercise-related images can be captured automatically regardless of whether people report they are attending to them.  相似文献

The authors examined the individual and combined influences of 2 factors that have been shown to benefit motor learning: an external focus of attention and enhanced performance expectancies. Another purpose of this study was to gain further insight into the mechanisms underlying these variables. In a factorial design, participants learning a novel motor skill (i.e., throwing with the non-dominant arm) were or were not given external focus instructions, and were or were not provided bogus positive social-comparative feedback to enhance their expectancies. This resulted in 4 groups: external focus, enhanced expectancy, external focus/enhanced expectancy and control. External focus instructions and enhanced expectancies had additive benefits for learning: the external focus/enhanced expectancy group demonstrated the greatest throwing accuracy on both retention and transfer tests, while the accuracy scores of the external focus and enhanced expectancy groups were lower, but higher than those of the control group. Furthermore, self-efficacy was increased by both external focus and enhanced expectancy, and predicted retention and transfer performance. Positive affect was heightened in the enhanced expectancy and external focus/enhanced expectancy groups after practice and predicted transfer performance. The findings suggest that the learning benefits of an external focus and enhanced expectancies mediate learning through partially different mechanisms.  相似文献
