Support for the proposition that the Quiet Eye (QE) duration reflects a period of response programming (including task parameterisation) has come from research showing that an increase in task difficulty is associated with increases in QE duration. Here, we build on previous research by manipulating three elements of task difficulty that correspond with different parameters of golf-putting performance; force production, impact quality and target line. Longer QE durations were found for more complex iterations of the task and furthermore, more sensitive analyses of the QE duration suggest that the early QE proportion (prior to movement initiation) is closely related to force production and impact quality. However, these increases in QE do not seem functional in terms of supporting improved performance. Further research is needed to explore QE's relationship with performance under conditions of increased difficulty.
支持“安静眼（QE）持续时间反映了反应编程阶段（包括任务参数设置）”这一观点的证据来自于相关研究，这些研究表明任务难度的增加与QE持续时间的增加有关。在此，我们基于先前的研究，通过操控与高尔夫推杆表现的不同参数相对应的任务难度的三个要素；力量产生、击球质量和目标线。我们发现，任务的更复杂迭代会有更长的QE持续时间，此外，对QE持续时间更敏感的分析表明，早期QE比例（运动开始前）与力量产生和击球质量密切相关。然而，就支持表现提升而言，这些QE的增加似乎并无作用。需要进一步的研究来探索在难度增加的条件下QE与表现之间的关系。
