所用的任务是一个自定进度的2选择串行响应任务，涉及两个氖灯作为信号和两个响应键在简单的空间对应的信号。在实验1中，比较了连续信号之间分别具有1/4、1/2和3/4交替的三种条件。结果显示，受试者在1/4交替时比3/4交替时走得更快。从信息论的观点来看，这两种情况下每个信号的信息量相同。这两种形式的顺序冗余的影响的不对称性可以归因于一些偏见的期望的主题或一些惯性现象有利于重复信号的反应。据推测，如果最后一种解释是正确的，如果在响应结束和下一个信号的出现之间引入时滞，则不对称性将减小。这是在实验2中对一组受试者进行的。这些受试者在相同的三种条件下工作，时间间隔为0.5秒。与另一组使用相同0.05秒的受试者相比，不对称性显着降低。实验1中的时间延迟。单独的RT分析证实了主要结论，选择过程涉及一个短暂的剩余效应，有利于重复。
The task used is a self-paced 2-choice serial responding task, involving two neon lamps as signals and two response keys in simple spatial correspondence with the signals. In Experiment 1, three conditions with respectively 1/4, 1/2 and 3/4 alternations between successive signals were compared. It appeared that subjects go faster with 1/4 than with 3/4 alternations. From the point of view of information theory, both conditions present the same amount of information per signal. The asymmetry in the effects of both forms of sequential redundancy could be attributed either to some bias in the expectations of the subjects or to some inertia phenomenon favouring responses to repeated signals. It was reasoned that if the last explanation was true, the asymmetry would be reduced if a time-lag was introduced between end of response and appearance of next signal. This was done for one group of subjects in Experiment 2. These subjects worked on the same three conditions, with a time-lag of 0.5 sec. The asymmetry was significantly reduced when compared with another group of subjects who worked with the same 0.05 sec. time-lag as in Experiment 1. Analysis of separate RTs confirmed the main conclusion that choice processes involve a transitory residual effect favouring repetitions.
