A new model for binocular processing is described. (i) In the bilateral either-eye channel, summation of the excitatory monocular responses is preceded by partial, reciprocal inhibition between each eye's responses. (ii) In the fused channel, the response is binocular, purely excitatory, multiplicative. (iii) The net binocular response of the system is a sum of the outputs of (i) and (ii). The model contains no independent monocular contributions to the net binocular response. All stimuli on corresponding retinal loci are processed in the either-eye channel; in addition, the fused channel responds to stimuli that are near 0-phase interocularly. The model is sufficiently general to account for binocular performance at the differential luminance threshold and in suprathreshold contrast matching, and it also offers a novel explanation for interocular transfer of adaptation. Plausibility of the model is briefly considered with regard to visual neurophysiology.
本文描述了一种双目处理的新模型。（i）在双侧单眼通道中，兴奋性单眼反应的总和之前，每只眼睛的反应之间存在部分相互抑制。（ii）在融合通道中，反应是双目、纯兴奋性、乘法性的。（iii）系统的净双目反应是（i）和（ii）输出的总和。该模型对净双目反应没有独立的单眼贡献。对应视网膜位点上的所有刺激都在单眼通道中进行处理；此外，融合通道对两眼间相位接近0的刺激做出反应。该模型具有足够的通用性，能够解释差异亮度阈值和超阈值对比度匹配时的双目性能，并且还为适应的双眼间转移提供了一种新的解释。文中简要考虑了该模型在视觉神经生理学方面的合理性。
