本文介绍了从心理物理实验的结果，人类的双眼竞争的中央和周边视觉。结果表明，一个给定的眼睛的竞争对手的目标的独家可见性期间的发病率随着目标尺寸的减小而增加，并且对于一个给定大小的目标独家可见性随着视网膜偏心率而增加。控制措施证实，这些结果并不完全归因于降低周边敏锐度，Troxler的效果，或空间频率。我们计算的最小尺寸的刺激，将导致一个标准水平的独家可见性的一只或另一只眼睛，这是我们的术语的空间区的双眼竞争。与偏心率竞争的空间区域的估计大小的变化相比，人类皮层放大率的估计有利。我们提出了一个模型，假设同心组织的竞争区。这些区域并不独立地发挥作用，而是表现出高度的相互兴奋协同性。该模型有多个解决方案的中心凹区的大小，但最好的拟合预测的直径为5.3或7.3分钟的视角;这些值吻合很好地与我们的经验估计的中心凹区的大小。
This paper presents results from psychophysical experiments on human binocular rivalry in central and peripheral vision. Results show that the incidence of periods of exclusive visibility of a given eye's rival target increased with decreasing target size, and for a given sized target exclusive visibility increased with retinal eccentricity. Control measures confirmed that these results were not attributable solely to reduced peripheral acuity, to Troxler's effect, or to spatial frequency. We computed the minimum-sized stimulus that would lead to a criterion level of exclusive visibility of one or the other eye; this we term the spatial zone of binocular rivalry. The change in estimated size of spatial zones of rivalry with eccentricity compares favorably with estimates of human cortical magnification. We propose a model that assumes concentrically organized zones of rivalry. These zones do not function independently, but instead exhibit a high degree of mutual excitatory cooperativity. The model has multiple solutions for the foveal zone size, but the best fits predict a diameter of 5.3 or 7.3 min of visual angle; these values dovetail nicely with our empirical estimates of the foveal zone size.
