Spontaneous strategy employment is important for memory performance, but systematic research on strategy use and within-task evolvement is limited. This online study aimed to replicate three main findings by Waris and colleagues in (2021): in word-list learning, spontaneous strategy use (1) predicts better task performance, (2) stabilizes along the task, and (3) increases during the first two task blocks. We administered a shortened version of their original real-word list-learning task to 209 neurotypical adults. Their first finding was partly replicated: manipulation strategies (grouping, visualization, association, narrative, other strategy) but not maintenance strategies (rehearsal/repetition, selective focus) were associated with superior word recall. The second finding on the decrease in strategy changers over task blocks was replicated. The third finding turned out to be misguided: neither our nor the original study showed task-initial increase in strategy use in the real-word learning condition. Our results confirm the important role of spontaneous strategies in understanding memory performance and the existence of task-initial dynamics in strategy employment. They support the general conclusions by Waris and colleagues: task demands can trigger strategy use even in a familiar task like learning a list of common words, and evolution of strategy use during a memory task reflects cognitive skill learning.
自发策略的运用对记忆表现很重要,但关于策略使用和任务过程中演变的系统研究有限。这项在线研究旨在复现瓦里斯及其同事在2021年的三项主要发现:在单词列表学习中,自发策略的使用(1)能预测更好的任务表现,(2)在任务过程中保持稳定,以及(3)在前两个任务块中增加。我们对209名神经典型成年人进行了他们原始真实单词列表学习任务的简化版测试。他们的第一个发现部分得到了复现:操纵策略(分组、可视化、联想、叙述、其他策略)而非维持策略(复述/重复、选择性聚焦)与更好的单词回忆相关。关于策略改变者在任务块中减少的第二个发现得到了复现。第三个发现被证明是有误导性的:无论是我们的研究还是原始研究,在真实单词学习条件下都未显示出任务开始时策略使用的增加。我们的结果证实了自发策略在理解记忆表现中的重要作用以及策略运用中任务开始时动态变化的存在。它们支持了瓦里斯及其同事的总体结论:任务需求即使在像学习一串常见单词这样熟悉的任务中也能触发策略使用,并且记忆任务中策略使用的演变反映了认知技能的学习。
