The relationship between emotion and motor action has been previously examined using relatively simple motor tasks. However, there has been limited research using more complex physical tasks. One such complex physical task is high-angle climbing. In this experiment, we examined the performance of climbers in a dual climbing and word memory task, in which they were asked to recall fear-related or neutral words after the climb, as well as single-task performance. Climbing distance, efficiency, and word recall all significantly decreased in the dual-task conditions, relative to the single tasks. Climbing distance and efficiency also decreased in the fear word dual task, relative to the neutral word memory dual task. Subjective measures of performance indicated that climbers were aware of impaired climbing performance in the dual tasks, relative to the climbing-only condition, but that they were not aware of the increased impairment caused by the fear words. These findings have important theoretical and practical implications, particularly in occupational settings requiring climbing-like operations, such as fire-fighting and search and rescue.
此前，人们通过相对简单的运动任务来研究情绪与运动行为之间的关系。然而，使用更复杂身体任务的研究却很有限。高角度攀爬就是这样一项复杂的身体任务。在本实验中，我们考察了攀岩者在攀爬与单词记忆双重任务中的表现，即要求他们在攀爬后回忆与恐惧相关或中性的单词，以及单任务表现。与单任务相比，在双重任务条件下，攀爬距离、效率和单词回忆均显著下降。相对于中性单词记忆双重任务，在恐惧单词双重任务中，攀爬距离和效率也有所下降。主观表现指标表明，与仅进行攀爬的情况相比，攀岩者意识到在双重任务中攀爬表现受损，但他们并未意识到恐惧单词会导致损伤加剧。这些发现具有重要的理论和实际意义，特别是在需要类似攀爬操作的职业环境中，如消防和搜救工作。
