A paper published recently in Perception has drawn attention to a question that appears to mystify psychologists, yet yields simply to the well-known law of reflection. The question of why a mirror reverses left and right, but not up and down, is explained in this paper, in terms of physical optics. The question of how mirror-reflected objects are perceived remains, of course, a psychological one.
最近发表在《感知》杂志上的一篇论文引起了人们对一个问题的关注，这个问题似乎让心理学家感到困惑，但却可以用众所周知的反射定律轻松解决。本文从物理光学的角度解释了为什么镜子会左右颠倒，而不会上下颠倒这个问题。当然，镜子反射的物体是如何被感知的问题仍然是一个心理学问题。
