在本研究中，我们通过向被试提供短期记忆(STM)任务策略培训来检验策略使用在工作记忆任务中的作用。在实验一中，受试者接受了四次使用故事形成(即链接)策略的培训。在STM和WM任务表现方面，从前测到后测(培训后)都有实质性的改善。实验2表明，控制组参与者的工作记忆任务没有得到改善，他们被给予了相同数量的练习，但没有得到策略指导。培训前对参与者在STM任务上的策略使用的评估表明，更多的策略型参与者表现出更好的WM任务表现和更好的口语技能。这些结果支持了我们的假设，即策略使用会影响工作记忆任务的绩效。
In this study, we examine the role of strategy use in working memory (WM) tasks by providing shortterm memory (STM) task strategy training to participants. In Experiment I, the participants received four sessions of training to use a story-formation (i.e., chaining) strategy. There were substantial improvements from pretest to posttest (after training) in terms of both STM and WM task performance. Experiment 2 demonstrated that WM task improvement did not occur for control participants, who were given the same amount of practice but were not provided with strategy instructions. An assessment of participants' strategy use on the STM task before training indicated that more strategic participants displayed better WM task performance and better verbal skills. These results support our hypothesis that strategy use influences performance on WM tasks.
