Cowey and Rolls have shown that the magnification factor with which the retina is imaged onto the striate cortex is proportional to visual acuity. Schwartz has used this to derive how visual peripheral acuity in the human varies with distance from the fovea, in good agreement with experiment. The same reasoning applied to the map of the lower half of the field of view as imaged onto the striate cortex of the cat indicates that the cat fixating a point up to about 100 cm in front of him sees the foreground portion of the horizontal surface on which he is standing approximately uniformly blurred.
考伊和罗尔斯已经表明，视网膜成像于纹状皮质上的放大系数与视敏度成正比。施瓦茨利用这一点推导出人类视觉周边视敏度如何随离中央凹的距离而变化，这与实验结果高度吻合。将同样的推理应用于成像于猫的纹状皮质上的下半视野图，结果表明，当猫注视其前方约100厘米处的一点时，它所看到的自己站立的水平表面的前景部分大致均匀地模糊不清。
