This study aimed at uncovering factors influencing execution of memory strategies and at furthering our understanding of ageing effects on memory performance. To achieve this end, we investigated strategy sequential difficulty (SSD) effects recently demonstrated by Uittenhove and Lemaire in the domain of problem solving. We found that both young and older participants correctly recalled more words using a sentence-construction strategy when this strategy followed an easier strategy (i.e., repetition strategy) or a harder strategy (i.e., mental-image strategy). These SSD effects were of equal magnitude in young and older adults, correlated significantly with Stroop performance in both young and older adults and correlated with N-back performance only in young adults. These findings have important implications for furthering our understanding of memory strategy execution and age-related variations in memory performance, as well for understanding mechanisms underlying SSD effects.
本研究旨在揭示影响记忆策略执行的因素，并加深我们对衰老对记忆表现影响的理解。为实现这一目标，我们研究了Uittenhove和Lemaire最近在问题解决领域所证明的策略顺序难度（SSD）效应。我们发现，当句子构建策略（即重复策略）之后采用较容易的策略或较难的策略（即心理意象策略）时，年轻和年长参与者使用该策略正确回忆出的单词更多。这些SSD效应在年轻人和老年人中大小相同，在年轻人和老年人中均与斯特鲁普任务表现显著相关，且仅在年轻人中与n-back任务表现相关。这些发现对于加深我们对记忆策略执行以及记忆表现中与年龄相关的差异的理解，以及理解SSD效应背后的机制具有重要意义。
