Abstract

Flicker response curves (man) obtained with images formed entirely within the fovea are like those secured with lower animals having only one general class of retinal receptors. They are normal probability integrals (F vs. log I(m)), and the properties of their parameters agree with those for visually simplex animals and for the "cone" portions of contours exhibiting visual duplexity. By several different procedures, involving experimental modifications of the "cone" curve, the "rod" part of the typical human duplex curve can be obtained free from overlapping by the extrapolated "cone" curve. It then has the probability integral form which the lower segment does not directly exhibit when combined with "cone" effects. These results are discussed with reference to the statistical nature of the fundamental form of the flicker contour and to the interpretation of duplex curves produced by the neural integration of two independently modifiable groups of sensory effects.

摘要

（人类）完全在中央凹内形成的闪烁反应曲线类似于那些只有一类视网膜感受器的低等动物的曲线。它们是正常的概率积分（F 与 log I(m)），并且其参数的性质与视觉单态动物和表现出视觉双重性的“锥体”部分的轮廓的参数一致。通过几种不同的程序，包括对“锥体”曲线进行实验性修改，可以获得典型的人类双重曲线的“杆”部分，而不会与外推的“锥体”曲线重叠。然后，它具有概率积分形式，当与“锥体”效应结合时，较低部分不会直接显示。这些结果是根据闪烁轮廓的基本形式的统计性质以及通过两个独立可修改的感觉效应组的神经整合产生的双重曲线的解释来讨论的。
