Abstract

We move our eyes more often than our heart beats. Our brain seems to cope effortlessly with the consequences of these rapid visual alterations, but a new study shows that similar scene changes in the absence of eye movements delay the speed of information processing. So are there costs in constantly shifting our focus of gaze?

摘要

我们眼睛移动的频率比心跳还高。我们的大脑似乎能轻松应对这些快速视觉变化带来的后果，但一项新研究表明，在没有眼球运动的情况下出现类似的场景变化会延迟信息处理的速度。那么，不断转移注视焦点是否存在代价呢？
