摘要 为了考察不同海拔高度低氧环境对高原世居人群视觉搜索能力的影响,以及这种影响的海拔效应。此次研究以剑桥认知系统(CANTAB)为测试工具,采用视觉搜索测试任务(MTS),以出生和生长在三个海拔(3000m、3800m和4500m)的40名、37名和43名藏族大学生为被试开展实验。结果发现:在选取的正确率和平均正确反应时间两个指标上,三组被试的反应均不存在显著差异。正确率,F(2,117)=0.07,p> 0.05;平均正确反应时间,F(2,117)=0.23,p> 0.05。此研究条件下,没有发现高海拔低氧环境对高原世居人群视觉搜索能力的影响存在海拔效应的证据。但这一结果还需在后续研究中加以确证。
