Altitude hypoxia can impair sensory and cognitive functions, from causing slowed responses to sensory hallucinations. In a field study, we tested 12 expeditioners at varied altitudes (low: 1696 m; high: 4556 m) with a simple auditory detection task and a dichotic listening paradigm in which a voice was presented, lateralized, within a binaural white noise stream. Slower reaction times and a reduced right ear advantage might be expected at high (vs. low) altitude, due to hypoxia. The participants' performances on both tasks did not differ between conditions, revealing that these functions are resistant to short-term hypoxia in young healthy adults.
高原缺氧会损害感觉和认知功能，导致反应迟钝和出现感觉幻觉。在一项野外研究中，我们用一个简单的听觉探测任务和一个双耳分听范式测试了 12 名在不同海拔高度的探险者（低海拔：1696 米；高海拔：4556 米），其中一个声音在双耳白噪声流中呈现，并偏向一侧。由于缺氧，预计在高海拔（与低海拔相比）时反应时间会更慢，右耳优势会降低。参与者在两项任务中的表现都没有因条件而异，这表明这些功能在年轻健康成年人中对短期缺氧有抵抗力。
