We examined the impact of increasing cognitive load on climbing performance and the impact of climbing on concurrent cognitive task performance.
Generally when two tasks are performed simultaneously performance of one or both suffers relative to performance of each alone. Such dual task decrement is not confined to competing cognitive tasks, but has also been found when one task involves demanding physical activity.
Skilled climbers performed a traverse climb alone and in combination with low and high cognitive load counting tasks, which were also performed alone.
In more realistic physical settings, physical and cognitive tasks will interfere, unlike what some literature using laboratory physical tasks may indicate.
Compared to single task (climb only) performance concurrent counting and climbing resulted in impaired performance. However, climbers appeared to prioritize climbing over cognitive task performance.
The results and this program of research have implications for occupations that involve concurrent demanding physical activity and cognitive task performance. PRéCIS: High risk, physical tasks in real world conditions appear to hinder cognitive performance more so than low-risk physical tasks carried out in laboratory conditions.
研究认知负荷增加对攀爬表现的影响，以及攀爬对同时进行的认知任务表现的影响。
一般来说，当两个任务同时进行时，一个或两个任务的表现相对于单独完成时会受到影响。这种双重任务的减少不仅限于竞争认知任务，当一项任务涉及到需要体力活动时，也会发现这种情况。
熟练的攀岩者单独进行横移攀爬，以及在单独进行的同时进行低认知负荷和高认知负荷计数任务。
在更现实的物理环境中，物理任务和认知任务会相互干扰，不像一些使用实验室物理任务的文献可能表明的那样。
与单一任务（仅攀爬）相比，同时进行计数和攀爬会导致表现受损。然而，攀岩者似乎更优先考虑攀爬而不是认知任务表现。
研究结果和这项研究计划对涉及同时进行高风险体力活动和认知任务表现的职业具有影响。
