四个实验考察了高频词在短时记忆任务中占优势的机制。实验一证明了词频对记忆广度的影响，这种影响与语速的差异无关。实验2和实验3表明，词频对跨序列位置的序列回忆有正向影响，但实验4表明，这种效应在向后回忆时被取消。提出了一个模型，该模型包括一个编辑整合过程，该过程操作来“清理”腐烂的短期记忆痕迹，并使用R.Schweickert(1993)描述的多项式处理树模型来提供对来自实验2、3和4的数据的定量拟合。
Four experiments investigated the mechanisms responsible for the advantage enjoyed by high-frequency words in short-term memory tasks. Experiment 1 demonstrated effects of word frequency on memory span that were independent of differences in speech rate. Experiments 2 and 3 showed that word frequency has an increasing effect on serial recall across serial positions, but Experiment 4 showed that this effect was abolished for backward recall. A model that includes a redintegration process that operates to ''clean up'' decayed short-term memory traces is proposed, and the multinomial processing tree model described by R. Schweickert (1993) is used to provide a quantitative fit to data from Experiments 2, 3, and 4.
