视知觉总存在一个可知觉的最小尺度,临床上把它作为视觉系统对视野信息感知的敏锐程度的检测指标。现行的这类检测零碎而且片面,本文把它们提高到系统的理论的高度,并提出一些新的检测的设想。
Visual perception always exists a minimum scale that can be perceived, and it is clinically used as a visual indicator of how sensitive the visual system is to perception of visual field information. The current tests of this type are fragmentary and one-sided. In this paper, they are raised to the theoretical level of the system and some new ideas for testing are put forward.
