排球运动员接发球过程中视觉搜索特征的研究 总被引：2，自引：0，他引：2
以33名不同水平排球运动员为被试,将时间阻断范式、眼动记录技术相结合,探讨排球运动员接发球过程中的视觉搜索特征。结果表明:在接发球过程中,不同水平排球运动员的视觉搜索特征存在显著差异。优秀排球运动员可以根据运动情景中任务的变化迅速调整视觉搜索模式,在接发球的预期阶段采用了注视次数少、注视持续时间长、眼跳距离小、注视轨迹简单、集中的搜索模式;在动作操作阶段采用了注视次数多、注视持续时间短、眼跳距离大、注视轨迹分散成网状的搜索模式。优秀排球运动员对发球落点进行预判时,在反应时和准确性指标上存在明显的优势,但是,随着运动水平的提高,反应准确性不是优秀排球运动员预期能力的主要区分标准。提示:对于测试、评价运动员在运动情景中的信息加工处理能力不能根据单一运动情景的眼动特征进行,要综合运动情景中的不同任务的眼动指标和行为预判探讨运动员在运动过程中的视觉搜索特征。 相似文献

Abstract We examined the influence of instructions on decision-making accuracy using video simulations of game-specific scenarios in Australian football. Skilled performers (average age of 23.4 ± 4.2 years) differing in experience (range 0 to 339 Australian Football League (AFL) matches) assumed the role of the key attacker and verbally indicated their kicking decision. Participants were randomly stratified into three groups: (1) LOOSE (n = 15) – instructed to “keep the ball away from the loose defender”; (2) TTF (n = 15) – instructed to “take the first option”; and (3) NI (control) (n = 16) – given no instructions. Gaze behaviour for a subset of participants (n = 20) was recorded. In the scenarios with an even number of attacking and defensive players, the decision-making accuracy of LOOSE was greater than TTF. This difference was most evident for lesser experienced performers, highlighting that lesser experienced performers are more affected by instructional foci than experienced performers. Gaze behaviour was not affected by instructional foci, but visual search rate was greater in scenarios of greater player number and complexity. 相似文献

信息量与认知负荷对羽毛球运动员视觉搜索特征的影响 总被引：3，自引：0，他引：3
选取14名羽毛球专业运动员和14名大学生初学者为被试,以羽毛球专项情境中对手即将回球的动作前情境图片预判为反应任务,探讨被试在不同信息量与认知负荷情况下知觉预判绩效及眼动特征。结果表明:运动员与初学者利用更多的信息来加快动作预判速度;运动员动作预判速度要快于初学者,二者在简单任务中的动作预判准确性优于复杂任务中的预判准确性;信息量主要影响运动员动作预判准确性。运动员视觉搜索的注视时间低于初学者;高信息量注视时间少于低信息量的注视时间,且运动员比初学者注视频率更少。运动员注视次数少于初学者;眼跳距离多于初学者;运动员注视轨迹比初学者更为集中。在视觉搜索分配上,运动员与初学者都主要关注球拍与持拍臂,但是在复杂任务与高信息量中,运动员比初学者更关注场上对手与场地位置关系。 相似文献

The ability to quickly locate objects within the visual field has a significant influence on athletic performance. Saccades are conjugate eye movements responsible for the rapid shift that brings a new part of the visual field into foveal vision. The aim of this study was to investigate the effects of sport expertise and intense physical effort on saccade dynamics during a free-viewing visual search task in skilled soccer players. Two groups of male subjects participated in this study: 18 soccer players and 18 non-athletes as the control group. Two sessions of visual search tasks without a sport-specific design were employed. Eye movements during the visual search tasks were recorded binocularly. Between pre- and post-test sessions, athletes performed a maximal incremental treadmill test. Cardiorespiratory parameters were measured continuously. Capillary lactate samples were collected. Pre-test findings indicated that athletes, in comparison to non-athletes, achieve higher values of the following characteristics of saccades (1) average acceleration, (2) acceleration peak, (3) deceleration peak, and (4) average velocity. An increase in post-test saccade duration and a decrease in post-test saccade velocity was observed in athletes due to the strenuous physical effort in relation to the pre-test state. Athletes may transfer high saccadic function efficiency to non-specific visual stimuli. The findings partially confirm that physical exertion can reduce oculomotor efficiency in athletes. 相似文献

Abstract 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

In search of key-performance predictors in sailing, we examined to what degree visual search, movement behaviour and boat control contribute to skilled performance while rounding the windward mark. To this end, we analysed 62 windward mark roundings sailed without opponents and 40 windward mark roundings sailed with opponents while competing in small regattas. Across conditions, results revealed that better performances were related to gazing more to the tangent point during the actual rounding. More specifically, in the condition without opponents, skilled performance was associated with gazing more outside the dinghy during the actual rounding, while in the condition with opponents, superior performance was related to gazing less outside the dinghy. With respect to movement behaviour, superior performance was associated with the release of the trimming lines close to rounding the mark. In addition, better performances were related to approaching the mark with little heel, yet heeling the boat more to the windward side when being close to the mark. Potential implications for practice are suggested for each phase of the windward mark rounding. 相似文献
