现在出现的情况是，视觉通常受到物体间距的限制，而不是尺寸。视觉系统通过检测并结合其特征来识别物体。当物体靠得太近，几个物体的特征组合成一个杂乱的物体时，就会发生“拥挤”。在这里，我们回顾了爆炸的研究拥挤在光栅歧视，字母和人脸识别，视觉搜索，选择性注意，阅读，并找到一个普遍的原则，布玛法。防止拥挤所需的临界间距对所有物体都是相等的，尽管不同物体之间的效果较弱。此外，在皮层的临界间距是独立的对象的位置，在视野的临界间距是成比例的固定对象的距离。对象间距超过临界间距的区域是“非拥挤窗口”。观察者无法识别此窗口之外的对象，其大小限制了阅读和搜索的速度。
It is now emerging that vision is usually limited by object spacing rather than size. The visual system recognizes an object by detecting and then combining its features. ‘Crowding’ occurs when objects are too close together and features from several objects are combined into a jumbled percept. Here, we review the explosion of studies on crowding—in grating discrimination, letter and face recognition, visual search, selective attention, and reading—and find a universal principle, the Bouma law. The critical spacing required to prevent crowding is equal for all objects, although the effect is weaker between dissimilar objects. Furthermore, critical spacing at the cortex is independent of object position, and critical spacing at the visual field is proportional to object distance from fixation. The region where object spacing exceeds critical spacing is the ‘uncrowded window’. Observers cannot recognize objects outside of this window and its size limits the speed of reading and search.
