Orthogonally oriented sinusoidal luminance gratings were dichoptically presented to the observers' left and right eyes. During the subsequent binocular rivalry, a small target was briefly presented (4AFC) to probe the strength of interocular suppression at various temporal latencies. Both stationary and moving rivalrous patterns were investigated. The purpose of experiment 1 was to compare the temporal characteristics of stationary and motion rivalry (0 and 1.2 deg s-1), while that of experiment 2 was to examine rivalry suppression for higher speeds (2 and 4 deg s-1). In all cases, it was found that the strength of suppression remained essentially constant throughout a single phase of binocular rivalry. The results of the investigation also revealed that moving rivalrous patterns lead to greater magnitudes of interocular suppression than static patterns. Despite these differences in the strength of suppression, the results of both experiments show that the temporal characteristics of motion and static rivalry are essentially identical.
将正交取向的正弦亮度光栅分别呈现给观察者的左眼和右眼。在随后的双眼竞争期间，短暂呈现一个小目标（4AFC），以探测不同时间延迟下的眼间抑制强度。对静止和运动的竞争模式都进行了研究。实验1的目的是比较静止和运动竞争（0和1.2度/秒）的时间特征，而实验2的目的是检验更高速度（2和4度/秒）下的竞争抑制情况。在所有情况下，研究发现，在双眼竞争的单个阶段中，抑制强度基本保持不变。调查结果还表明，运动的竞争模式比静态模式导致更大程度的眼间抑制。尽管在抑制强度上存在这些差异，但两个实验的结果都表明，运动和静态竞争的时间特征基本相同。
