Phase discrimination thresholds were measured for yellow/green isoluminant and non-isoluminant compound gratings in which the amplitude of the two components (f and 3f) was twice the detection threshold. The phase discrimination threshold at isoluminance was worse than in all the other conditions, which gave broadly similar threshold data. It is suggested that this is due to a positional uncertainty in the neural representation of the isoluminant stimuli.
针对黄色/绿色等亮度和非等亮度复合光栅测量了相位辨别阈值，其中两个成分（f和3f）的幅度是检测阈值的两倍。等亮度条件下的相位辨别阈值比所有其他条件下都要差，其他条件下得到的数据阈值大致相似。据推测，这是由于等亮度刺激的神经表征中存在位置不确定性。
