The ability to imagine hypothetical events in one's personal future is thought to involve a number of constituent cognitive processes. We investigated the extent to which individual differences in working memory capacity contribute to facets of episodic future thought. College students completed simple and complex measures of working memory and were cued to recall autobiographical memories and imagine future autobiographical events consisting of varying levels of specificity (i.e., ranging from generic to increasingly specific and detailed events). Consistent with previous findings, future thought was related to analogous measures of autobiographical memory, likely reflecting overlapping cognitive factors supporting both past and future thought. Additionally, after controlling for autobiographical memory, residual working memory variance independently predicted future episodic specificity. We suggest that when imagining future events, working memory contributes to the construction of a single, coherent, future event depiction, but not to the retrieval or elaboration of event details.
人们认为,想象个人未来假设事件的能力涉及到许多组成认知过程。我们研究了工作记忆容量的个体差异在多大程度上影响情景式未来思维的各个方面。大学生完成了简单和复杂的工作记忆测试,并被提示回忆自传体记忆和想象未来自传体事件,这些事件的具体程度不同(即从一般到越来越具体和详细的事件)。与之前的发现一致,未来的思维与类似的自传体记忆测量有关,这可能反映了支持过去和未来思维的重叠认知因素。此外,在控制自传体记忆后,剩余的工作记忆方差独立预测未来情景式的具体性。我们认为,在想象未来事件时,工作记忆有助于构建一个单一的、连贯的、未来事件的描述,而不是对事件细节的检索或阐述。
