In normal subjects, binocular rivalry suppression takes time to build up (Wolfe, 1986a). The time courses of interocular suppression are different and heterogeneous in amblyopic subjects (de Belsunce & Sireteanu, 1991). In the present study, we found that, in normal observers, progressive reduction of one eye's stimulus luminance with neutral density filters produces time courses similar to those of amblyopic subjects. Conversely, in amblyopes, attenuation of the dominant eye's stimulus produces time courses similar to those of normal observers. Under conditions of balancing of the two eyes, amblyopes experience alternating suppression, similarly to binocular rivalry of normals.
在正常受试者中，双眼竞争抑制的形成需要时间（沃尔夫，1986a）。弱视受试者两眼间抑制的时间进程不同且不均匀（德贝尔松斯和西雷塔努，1991）。在本研究中，我们发现，在正常观察者中，用中性密度滤光片逐渐降低一只眼睛的刺激亮度会产生与弱视受试者相似的时间进程。相反，在弱视患者中，优势眼刺激的减弱会产生与正常观察者相似的时间进程。在两眼平衡的条件下，弱视患者会经历交替抑制，这与正常人的双眼竞争类似。
