Three experiments examined the processing capacity required to use sequential information in a serial reaction time task with partially predictable sequences. The first two experiments varied the response stimulus interval (RSI) between 0 and 500 msec and found the relative advantage of the high-probability stimulus to be independent of the length of the RSI. The third experiment compared utilization of sequential information either with or without a secondary task. The secondary task did not affect the high-probability stimulus but did increase the amount of time required to respond to the low-probability events. The results are discussed in terms of the attentional demands of memory access.
三项实验检验了在部分可预测序列的序列反应时任务中使用顺序信息所需的处理能力。前两个实验改变了反应刺激间隔（RSI）在 0 到 500 毫秒之间，发现高概率刺激的相对优势与 RSI 的长度无关。第三个实验比较了在有或没有次要任务的情况下对序列信息的利用。次要任务不影响高概率刺激，但确实增加了对低概率事件做出反应所需的时间。结果根据记忆访问的注意力需求进行了讨论。
