問題 人在仰、俯观察时,对象看起来显得小,是生活中的一个熟知現象,但这一现象的原因及其規律性至今还不清楚。在心理学中,这一問題的研究曾与日月大小錯觉联系在一起。以托勒密(Ptolemy)为代表的古老理論认为,仰视时由于观察者与对象之間的空間是不充滿的,造成了对距离的低估,于是把空中的物体放在视角內的近处来判断,因而显得小。 When the problem person looks upwards or downwards, the subject appears to be small and is a well-known phenomenon in his life. However, the reason for this phenomenon and its regularity are still unclear. In psychology, the study of this issue has been associated with the illusion of the size of the sun and the moon. The ancient theory represented by Ptolemy argues that, due to the lack of space between the observer and the object when looking up, the distance to the object is underestimated, and the object in the air is brought close to the point of view Judgment, therefore appears small.
