参与者被要求使用初始字母和语义类别搜索策略，使用大小类别来生成尽可能多的单词。记录每个受试者在每个任务上的15-S时间片的产量。结果表明，在所有流利性任务中，初始时间片的产量最高，频率也最高。随着任务时间的增加，生产量减少，产生的物品的词频也减少。研究结果与这一观点一致，即在流利性任务的早期试验中，存在高频词的储存库，并且随着储存库的耗尽，产量和词频下降。
Participants were asked to generate as many words as possible using large and small category sizes with the initial letter and semantic category search strategies. The production of each participant for each 15-s time slice on each task was recorded. The results revealed that on all fluency tasks, the production in the initial time slice was highest and also of greatest frequency. As time on task increased the production decreased, as did the word frequency of the items produced. The results are consistent with the notion that there is a store of high-frequency words accessed during the early trials of the fluency tasks and as this store becomes exhausted the production and the word frequency decreases.
