当目标单个出现而没有其他物体靠近时,我们能更好看到目标的细节。这种接近物对目标可视度的干扰作用,即抑制性空间交互的形式之一,通常被称为拥挤。在空间视觉中拥挤普遍存在,如拥挤影响对两个条栅的分辨、游标辨别、立体影像、线段方向敏感度、字母锐度和字母对比敏感度。本文从多方位对拥挤效应做综述性介绍,让读者对拥挤现象具有一定深度的认识。
We can better see the details of the target when the target appears singly and no other objects come close. One of the forms of restraining space interaction, which is often called crowding, is the interfering effect of such approaching objects on the target’s visibility. Crowding is common in spatial vision, such as crowding affecting the resolution of two grids, cursor discrimination, stereo images, line direction sensitivity, alphabetic sharpness, and alphabet sensitivity. This article from a multi-directional overview of the crowding-in effect, so that readers have a certain depth of understanding of the crowded phenomenon.
