Abstract

The effects of emotion on memory are wide-ranging and powerful, but they are not uniform. Although there is agreement that emotion enhances memory for individual items, how it influences memory for the associated contextual details (relational memory, RM) remains debated. The prevalent view suggests that emotion impairs RM, but there is also evidence that emotion enhances RM. To reconcile these diverging results, we carried out three studies incorporating the following features: (1) testing RM with increased specificity, distinguishing between subjective (recollection based) and objective (item-context match) RM accuracy, (2) accounting for emotion-attention interactions via eye-tracking and task manipulation, and (3) using stimuli with integrated item-context content. Challenging the prevalent view, we identified both enhancing and impairing effects. First, emotion enhanced subjective RM, separately and when confirmed by accurate objective RM. Second, emotion impaired objective RM through attention capturing, but it enhanced RM accuracy when attentional effects were statistically accounted for using eye-tracking data. Third, emotion also enhanced RM when participants were cued to focus on contextual details during encoding, likely by increasing item-context binding. Finally, functional magnetic resonance imaging data recorded from a subset of participants showed that emotional enhancement of RM was associated with increased activity in the medial temporal lobe (MTL) and ventrolateral prefrontal cortex, along with increased intra-MTL and ventrolateral prefrontal cortex-MTL functional connectivity. Overall, these findings reconcile evidence regarding opposing effects of emotion on RM and point to possible training interventions to increase RM specificity in healthy functioning, posttraumatic stress disorder, and aging, by promoting item-context binding and diminishing memory decontextualization.

调和情绪对关系记忆的对立影响:行为、眼动追踪和脑成像研究。
情绪对记忆的影响是广泛而强大的,但并不一致。尽管人们一致认为情绪会增强对单个项目的记忆,但情绪如何影响对相关情境细节的记忆(关系记忆,RM)仍存在争议。流行的观点认为情绪会损害关系记忆,但也有证据表明情绪会增强关系记忆。为了调和这些不同的结果,我们进行了三项包含以下特征的研究:(1)以更高的特异性测试RM,区分主观(基于回忆)和客观(项目-上下文匹配)RM的准确性;(2)通过眼动跟踪和任务操作来考虑情绪-注意力的相互作用;(3)使用具有综合项目-上下文内容的刺激物。与普遍观点不同的是,我们同时发现了增强效应和损害效应。首先,情绪会单独增强主观RM,并通过准确的客观RM加以证实。其次,情绪会通过注意力捕捉损害客观RM,但当使用眼动追踪数据对注意力效应进行统计时,情绪会提高RM的准确性。第三,当被试在编码过程中被提示关注上下文细节时,情绪也会增强RM,这可能是通过增加项目-上下文的结合来实现的。最后,一部分参与者记录的功能磁共振成像数据显示,情绪对RM的增强与内侧颞叶(MTL)和腹外侧前额叶皮层活动的增加有关,同时内侧颞叶(MTL)和腹外侧前额叶皮层与内侧颞叶(MTL)的功能连接也增加了。总之,这些发现调和了情绪对RM的相反影响的证据,并指出了可能的训练干预措施,通过促进项目与上下文的结合和减少记忆的非上下文化,提高健康功能、创伤后应激障碍和衰老的RM特异性。(PsycInfo Database Record (c) 2024 APA, 版权所有)。

期刊介绍: The Journal of Experimental Psychology: General publishes articles describing empirical work that bridges the traditional interests of two or more communities of psychology. The work may touch on issues dealt with in JEP: Learning, Memory, and Cognition, JEP: Human Perception and Performance, JEP: Animal Behavior Processes, or JEP: Applied, but may also concern issues in other subdisciplines of psychology, including social processes, developmental processes, psychopathology, neuroscience, or computational modeling. Articles in JEP: General may be longer than the usual journal publication if necessary, but shorter articles that bridge subdisciplines will also be considered.
