We describe and evaluate a recall reconstruction hypothesis for working memory (WM), according to which items can be recovered from multiple memory representations. Across four experiments, participants recalled memoranda that were either integrated with or independent of the sentence content. We found consistently longer pauses accompanying the correct recall of integrated compared with independent words, supporting the argument that sentence memory could scaffold the access of target items. Integrated words were also more likely to be recalled correctly, dependent on the details of the task. Experiment 1 investigated the chronometry of spoken recall for word span and reading span, with participants completing an unfinished sentence in the latter case. Experiments 2 and 3 confirm recall time differences without using word generation requirements, while Experiment 4 used an item and order response choice paradigm with nonspoken responses. Data emphasise the value of recall timing in constraining theories of WM functioning.
我们描述并评估了一种关于工作记忆(WM)的回忆重建假设,根据该假设,项目可以从多个记忆表征中恢复。在四项实验中,参与者回忆与句子内容整合或独立的备忘录。我们发现,与独立单词相比,正确回忆整合单词时的停顿时间始终更长,这支持了句子记忆可以为目标项目的提取提供支撑的观点。根据任务的细节,整合单词也更有可能被正确回忆。实验1研究了单词广度和阅读广度的口语回忆计时,在后一种情况下,参与者要完成一个未完成的句子。实验2和3在不使用单词生成要求的情况下证实了回忆时间差异,而实验4使用了带有非口语反应的项目和顺序反应选择范式。数据强调了回忆计时在限制工作记忆功能理论方面的价值。
