本研究的目的是检验意识加工假说作为一种解释。焦虑和表现之间的关系该研究旨在确定有意识的处理性能的影响，同时控制了在以前的研究中确定的另一种注意力阈值的解释。参加者完成了60次高尔夫推杆。他们完成了3块10推杆在单一的任务，任务相关的阴影，和任务无关的音计数条件。每组3 × 10推杆在低焦虑和高焦虑条件下完成。焦虑升高使用教学设置。自我报告的努力和心率变异性的频谱分析被用来检查在不同的推杆条件下的努力模式。研究结果表明，性能受损的高焦虑阴影和音计数条件下，支持注意力阈值的解释。心率变异性的频谱分析表明，潜在的补偿性增加频谱功率在高频段与双任务把在低焦虑状态下不存在的高焦虑计音和阴影把条件，部分反映了性能的研究结果。没有发现自我报告的努力的影响。两者合计，性能和心率变异性的结果支持的焦虑/运动性能关系的注意力解释。
The aim of this study was to examine the conscious processing hypothesis as an explanation. of the anxiety/performance relationship. The study was designed to identify conscious processing performance effects while controlling for an alternative attentional threshold explanation identified in previous research. Participants completed 60 golf putts. They completed 3 blocks of 10 putts in single task, task-relevant shadowing, and task-irrelevant tone-counting conditions. Each set of 3 x 10 putts was completed in low and high anxiety conditions. Anxiety was elevated using an instructional set. Self-reported effort and spectral analysis of heart rate variability were used to examine the patterning of effort across the different putting conditions. Findings indicated that performance was impaired in the high anxiety shadowing and tone-counting conditions, supporting an attentional threshold interpretation. Spectral analysis of heart rate variability indicated that potential compensatory increases in spectral power in the high frequency band associated with dual-task putting in the low anxiety condition were absent in the high anxiety tone-counting and shadowing putting conditions, partially reflecting the performance findings. No effects were found for self-reported effort. Taken together, the performance and heart rate variability results support an attentional interpretation of the anxiety/motor performance relationship.
