The effects of altitude on human performance and cognition were evaluated in a field study performed on Mount Denali in Alaska during the summer of 1990. Climbers performed a series of perceptual, cognitive, and sensory-motor tasks before, during, and after climbing the West Buttress route on Denali. Relative to a matched control group that performed the tasks at sea level, the climbers showed deficits of learning and retention in perceptual and memory tasks. Furthermore, climbers performed more slowly on most tasks than did the control group, suggesting long-term deficits that may be attributed to repeated forays to high altitudes.
1990年夏天，在阿拉斯加的德纳里山进行了一项实地研究，评估了海拔高度对人类表现和认知的影响。登山者在攀登德纳里山西支线路线之前、期间和之后，完成了一系列感知、认知和感觉运动任务。相对于在海平面完成任务的匹配对照组，登山者在感知和记忆任务中的学习和记忆表现存在缺陷。此外，登山者在大多数任务上的完成速度比对照组慢，这表明长期的缺陷可能归因于多次前往高海拔地区。
