我们进行了三个实验，以考察单个说话者或不同说话者对包含词条的单词列表的回忆情况。在每个实验中，对于单个说话者所说的列表，回忆早期列表条目的效果要好于不同说话者所说的相同单词的列表。记忆预加载程序的使用表明，当后续列表中的单词由单个说话者说出时，对视觉呈现的预加载数字的回忆优于由不同说话者说出的单词。此外，一项回溯干扰任务表明，说话者变异性对早期列表项目回忆的影响不是由于在回忆时使用工作记忆中说话者特定的声音线索造成的。综上所述，结果表明，不同说话者生成的单词列表比单个说话者生成的单词列表在工作记忆中需要更多的处理资源。这些发现是从主动排练在将口语项目转移到长期记忆中所起的作用以及可能影响排练效率的因素的角度来讨论的。
Three experiments were conducted to investigate recall of lists of words containing items spoken by either a single talker or by different talkers. In each experiment, recall of early list items was better for lists spoken by a single talker than for lists of the same words spoken by different talkers. The use of a memory preload procedure demonstrated that recall of visually presented preload digits was superior when the words in a subsequent list were spoken by a single talker than by different talkers. In addition, a retroactive interference task demonstrated that the effects of talker variability on the recall of early list items were not due to use of talker-specific acoustic cues in working memory at the time of recall. Taken together, the results suggest that word lists produced by different talkers require more processing resources in working memory than do lists produced by a single talker. The findings are discussed in terms of the role that active rehearsal plays in the transfer of spoken items into long-term memory and the factors that may affect the efficiency of rehearsal.
