The effects of stress on directing attention within performance have been broadly explained by self-focus and distraction perspectives, where stress causes attention to be drawn internally or toward the sources of worry, respectively. Recent studies that have adopted manual aiming under different levels of stress have illuminated our understanding of the stress-performance framework. The present study seeks to elaborate on this current trend by introducing a sequential task, where the integration of individual movement segments enhances the demands on preparation and control, and thus closely examines the explanatory power of the self-focus and distraction perspectives. This study involved executing aiming movements solely to one-target (1T), or continuing by extending (2TE) and reversing (2TR) the limb to a second target. Participants were instructed to simply execute rapid and accurate movements (low-stress), and additionally provided a socio-comparative stressor (high-stress). While there was no one- (1 T vs. 2TE) or two-target (1T vs. 2TR) advantage, there was a shorter movement time in the first segment of the one-target task that appeared to dissipate when under high-stress. In addition, the high-stress conditions caused shorter reaction and pause times, while the proportion of the sequence time decreased within the pause, but increased within the second segment. Consequently, the overall sequence time failed to differ between low- and high-stress. These findings indicate that the online control of movement is accommodated under high-stress. We suggest these procedures unfold following a primary focus to uphold the performance outcome. Thus, these findings appear to be consistent with the distraction perspective.

自我聚焦和分散注意力的观点已广泛地解释了压力对在表演中引导注意力的影响，在这种情况下，压力导致注意力分别在内部或担心的源头产生。最近在不同压力水平下采用手动瞄准的研究阐明了我们对压力绩效框架的理解。本研究试图通过引入一个顺序任务来详细说明当前趋势，在该任务中，各个运动部分的集成会增强对准备和控制的要求，从而密切检查自我聚焦和分散注意力的解释力。这项研究涉及仅将瞄准运动执行到一个目标（1T），或者通过将肢体伸展（2TE）和反转（2TR）到第二个目标来继续。指示参与者简单地执行快速准确的动作（低压力），并另外提供一个与社会比较的压力源（高压力）。虽然没有一个目标（1T vs. 2TE）或两个目标（1T vs. 2TR）的优势，但是在高压力下，单目标任务的第一部分的运动时间似乎缩短了。此外，高压力条件导致较短的反应时间和暂停时间，而序列时间的比例在暂停内减少，但在第二段内增加。因此，整个序列时间在低应力和高应力之间没有差异。这些发现表明，在线运动控制是在高压力下进行的。我们建议这些程序应首先关注以保持性能结果。从而，
