The role of rehearsal in a varied set memory scanning task was investigated by asking the subjects to rehearse subvocally the one to four target characters cyclically at a self-paced rate until the probe was presented. After making a manual positive or negative response to the probe, the subjects reported the last item rehearsed before the probe was presented. The results indicate that, when the last rehearsed item matched the probe, RTs were significantly faster than when it differed. Mean RTs over target set size were generally well fit by linearly increasing RT functions, with comparable slope values for negative responses and positive responses when the last rehearsal was the same as or different from the probe. The data suggest that rehearsal may reduce the duration of the probe encoding stage through some mechanism of pathway activation by providing the subject with a generated representation of what may appear next as a probe.
研究通过要求被试者以自我调节的速度在循环中对一到四个目标字符进行默念复述，来探究在多样化的记忆扫描任务中复述的作用。在对探测做出手动的正或负反应后，被试者报告在探测呈现之前最后一次复述的项目。结果表明，当最后一次复述的项目与探测相匹配时，反应时显著快于不同时的情况。当最后一次复述与探测相同时或不同时，目标集大小的平均反应时通常很好地符合线性递增的反应时函数，负响应和正响应的斜率值相当。这些数据表明，通过某种通过激活通路提供可能作为探测出现的下一个项目的生成表示的机制，复述可能会通过减少探测编码阶段的持续时间来帮助被试者。
