在两个实验中，我们研究了动作可能性的感知变化作为一个功能的努力。在实验1中，参与者在一系列的试验中反复爬上攀岩墙，试验次数逐渐增加到10次，从而增加了体力。在攀登之前和过程中，参与者判断他们的最大可达高度和感知的努力。在另一天，参与者爬上另外10个试验，同时执行实际的最大范围。较高的感知用力与感知最大范围的减少有关，而实际范围并没有减少。然而，知觉的变化发生在任务执行的早期，当参与者还没有疲劳。当运动开始时，无论是感知的还是实际的最大范围似乎都没有受到影响。在实验2中，我们包括了疲劳试验。研究结果复制了实验1中观察到的感知的早期变化，这可能是由动手经验的任务。此外，在爬到筋疲力尽时，感知判断在很大程度上随着实际最大可达范围的变化而变化。因此，参与者的实际行动能力，而不是他们的身体疲劳状态本身，和感知的行动可能性之间似乎存在函数关系。
In two experiments we examined changes in the perception of action possibilities as a function of exertion. In Experiment 1, participants repeatedly climbed on a climbing wall in a series of trials that progressively increased in number to 10 trials, resulting in increased exertion. Before and during climbing, the participants judged their maximum reaching height and perceived exertion. On a separate day, participants climbed another 10 trials while performing actual maximum reaches. Higher perceived exertion was associated with decreases in perceived maximum reach while the actual reaches did not decrease. However, the perceptual changes occurred early during task execution when the participants were not yet fatigued. When exertion set in, neither perceived nor actual maximum reaching appeared to be affected. In Experiment 2, we included exhaustion trials. The findings replicated the early changes in perception observed in Experiment 1, which may be explained by hands-on experience with the task. Furthermore, while climbing to exhaustion, perceptual judgements largely changed in keeping with changes in the actual maximum reach. Thus, there appeared to be a functional relationship between participants' actual action capabilities, rather than their state of physical fatigue per se, and perceived action possibilities.
