The current study leveraged experimental and individual differences methodology to examine whether false memories across different list-learning tasks arise from a common cause. Participants completed multiple false memory (associative and conjunction lure), working memory (operation and reading span), and source monitoring (verbal and picture) tasks. Memory discriminability in the associative and conjunction tasks loaded onto a single (general) factor and were unaffected by warnings provided at encoding. Consistent with previous research, source-monitoring ability fully mediated the relation between working memory and false memories. Moreover, individuals with higher source monitoring-ability were better able to recall contextual information from encoding to correctly reject lures. These results suggest that there are stable individual differences in false remembering across tasks. The commonality across tasks may be due, at least in part, to the ability to effectively use disqualifying monitoring processes.
本研究利用实验和个体差异方法来检验不同列表学习任务中的错误记忆是否源于共同原因。参与者完成了多项错误记忆（联想和结合诱饵）、工作记忆（操作和阅读广度）和来源监测（言语和图片）任务。在联想和结合任务中的记忆辨别力加载到一个单一（通用）因素上，不受编码时提供的警告影响。与先前的研究一致，来源监测能力完全中介了工作记忆和错误记忆之间的关系。此外，来源监测能力较高的个体能够更好地回忆起从编码到正确拒绝诱饵的上下文信息。这些结果表明，在不同任务中存在稳定的错误记忆个体差异。任务之间的共性至少部分归因于有效使用排除监测过程的能力。
