We examined the impact of performing a cognitive task of varying loads and kayaking simultaneously, compared to performance on the same tasks individually.
When two tasks are performed together, performance often suffers compared to performance on either task alone. Interference not only occurs in competing cognitive tasks, but has also been found with certain physically demanding activities, such as climbing.
Skilled kayakers performed a kayak course on open water, performed a high and a low cognitive load tone counting task, and also performed the kayak and counting tasks simultaneously.
Despite some past research finding dual task facilitation with laboratory aerobic activities, simultaneous kayaking and tone counting led to dual-task interference.
Concurrent counting and kayaking led to performance impairments in both tasks, relative to single task performance.
The present results are applicable to occupations involving concurrent demanding physical activity and cognitive task performance, such as the work of first responders and military operators. PRéCIS: Kayaking, like climbing, appears to hinder cognitive performance more than the low-risk physical tasks carried out in laboratory conditions.
我们研究了同时进行不同负荷的认知任务和皮划艇运动的影响，并将其与单独完成相同任务的表现进行比较。
当两项任务同时进行时，与单独完成任何一项任务相比，表现往往会受到影响。干扰不仅会出现在相互竞争的认知任务中，在某些对体力要求较高的活动（如攀岩）中也被发现。
熟练的皮划艇运动员在开阔水域完成皮划艇课程，执行高认知负荷和低认知负荷的音调计数任务，同时也进行皮划艇和计数任务。
尽管过去一些研究发现实验室有氧运动存在双重任务促进作用，但同时进行皮划艇运动和音调计数会导致双重任务干扰。
相对于单任务表现，同时计数和划皮划艇会导致两项任务的表现受损。
目前的结果适用于涉及同时进行高要求体力活动和认知任务表现的职业，如急救人员和军事人员的工作。摘要：与在实验室条件下进行的低风险体力任务相比，皮划艇运动（如攀岩）似乎更能阻碍认知表现。
