两个信息被一分为二地呈现，受试者被要求“模仿”他们在一只耳朵上听到的任何信息。在中间的某个地方，两个段落被切换到相反的耳朵。实验对象偶尔会在休息时从错误的耳朵重复一到两个单词，但从来没有超过这个时间。通道中的过渡概率越高，他们就越有可能这样做。一种解释可能是“选择性滤波器”（Broadbent, 1958）通过选择性地提高来自被拒绝源的信号的阈值而不是作为全有或全无的障碍。
Two messages were presented dichotically and subjects were asked to “shadow” whatever they heard on one ear. Somewhere in the middle the two passages were switched to the opposite ears. Subjects occasionally repeated one or two words, at the break, from the wrong ear, but never transferred to it for longer than this. The higher the transition probabilities in the passage the more likely they were to do this. One explanation might be that the “selective filter” (Broadbent, 1958) acts by selectively raising thresholds for signals from the rejected sources rather than acting as an all-or-none barrier.
