The relation between working memory capacity (WMC) and recall from long-term memory (LTM) was examined in the current study. Participants performed multiple measures of delayed free recall varying in presentation duration and self-reported their strategy usage after each task. Participants also performed multiple measures of WMC. The results suggested that WMC and LTM recall were related, and part of this relation was due to effective strategy use. However, adaptive changes in strategy use and study time allocation were not related to WMC. Examining multiple variables with structural equation modeling suggested that the relation between WMC and LTM recall was due to variation in effective strategy use, search efficiency, and monitoring abilities. Furthermore, all variables were shown to account for individual differences in LTM recall. These results suggest that the relation between WMC and recall from LTM is due to multiple strategic factors operating at both encoding and retrieval. (PsycINFO Database Record
在本研究中，我们考察了工作记忆容量（WMC）与长期记忆（LTM）回忆之间的关系。参与者进行了多项延迟自由回忆测试，这些测试的呈现时间各不相同，并在每个任务后自我报告其策略使用情况。参与者还进行了多项WMC测试。结果表明，WMC与LTM回忆相关，且这种关系部分归因于有效的策略使用。然而，策略使用和学习时间分配的适应性变化与WMC无关。通过结构方程模型检验多个变量表明，WMC与LTM回忆之间的关系归因于有效策略使用、搜索效率和监控能力的差异。此外，所有变量都被证明可以解释LTM回忆中的个体差异。这些结果表明，WMC与LTM回忆之间的关系是由于在编码和检索过程中起作用的多个策略因素。（PsycINFO数据库记录）
