Strategy sequential difficulty effects are the findings that when participants execute strategies, performance is worse after a difficult strategy than after an easy strategy (Uittenhove & Lemaire, 2012). Strategy sequential difficulty effects are hypothesized to result from decreased working-memory resources following difficult strategy execution. In the present study we found a correlation between individuals' working memory and strategy sequential difficulty effects in arithmetic, supporting a working-memory account of these effects. Furthermore, we varied response-stimulus intervals, and we found decreased strategy sequential difficulty effects with increasing response-stimulus intervals. Implications of these findings for further understanding of strategic variations in human cognition are discussed.
策略顺序难度效应是指当参与者执行策略时，在执行较难策略之后的表现比在执行较易策略之后更差的现象（于滕霍夫和勒梅尔，2012年）。据推测，策略顺序难度效应是由于执行较难策略后工作记忆资源减少所致。在本研究中，我们发现个体的工作记忆与算术运算中的策略顺序难度效应之间存在相关性，这支持了对这些效应的工作记忆解释。此外，我们改变了反应-刺激间隔，并且发现随着反应-刺激间隔的增加，策略顺序难度效应减弱。本文讨论了这些发现对于进一步理解人类认知中策略变化的意义。
