视觉对于导航无疑很重要，尽管不是必需的，因为盲人在各种导航任务中的表现优于蒙住眼睛的同行。据信，盲人的上级表现是因为他们有效地利用了本体感受信号和环境线索，如温度和回声定位。我们假设，通过限制这些线索，盲人将失去他们的优势相比，控制空间导航任务。因此，我们评估了盲人和有视力的个人在小规模，触觉多T迷宫的表现。我们的研究结果表明，蒙眼视力控制优于盲人参与者的路线学习任务。这表明，与室内大型空间相反，小规模空间内的导航技能受益于视觉体验。NeuroReport 21：989-992（C）2010 Wolters Kluwer Health竖条Lippincott威廉姆斯和威尔金斯。
Vision is undoubtedly important for navigation although not essential as blind individuals outperform their blindfolded seeing counterparts in a variety of navigational tasks. It is believed that the blind's superior performance is because of their efficient use of proprioceptive signals and environmental cues such as temperature and echolocation. We hypothesize that by limiting these cues, blind individuals will lose their advantage compared with controls in spatial navigation tasks. We therefore evaluated the performance of blind and sighted individuals in small-scale, tactile multiple T mazes. Our results show that blindfolded sighted controls outperformed blind participants in the route-learning tasks. This suggests that, contrary to indoor large-scale spaces, navigational skills inside small-scale spaces benefit from visual experience.
