Efficient execution of strategies is crucial to memory performance and to age-related differences in this performance. Relative strategy complexity influences memory performance and aging effects on memory. Here, we aimed to further our understanding of the effects of relative strategy complexity by looking at the role of cognitive control functions and the time-course of the effects of relative strategy complexity. Thus, we manipulated inter-stimulus intervals (ISI) and assessed executive functions. Results showed that (a) performance as a function of the relative strategy difficulty of the current and previous trial was modulated by ISI, (b) these effects were modulated by inhibition capacities, and (c) significant age differences were found in the way ISI modulates relative strategy difficulty. These findings have important implications for understanding the relationships between aging, executive control, and strategy execution in episodic memory.
策略的有效执行对于记忆表现以及该表现中与年龄相关的差异至关重要。相对策略复杂性会影响记忆表现以及衰老对记忆的影响。在此，我们旨在通过研究认知控制功能的作用以及相对策略复杂性影响的时间进程，进一步加深对相对策略复杂性影响的理解。因此，我们操纵了刺激间隔（ISI）并评估了执行功能。结果表明：（a）作为当前和先前试验相对策略难度函数的表现受到ISI的调节；（b）这些影响受到抑制能力的调节；（c）在ISI调节相对策略难度的方式上发现了显著的年龄差异。这些发现对于理解情景记忆中衰老、执行控制和策略执行之间的关系具有重要意义。
