Memory control (MC) ability is critical for people's mental and physical health. Previous research had conceptually demonstrated that MC ability has close relationship with reappraisal. However, experimental evidence supporting the relationship was limited. Thus, in the present study, we investigated how MC and reappraisal are linked, both in behavior and in the brain.
The habitual use of reappraisal was assessed by Emotion Regulation Questionnaire, and memory control ability was measured through directed forgetting task. Resting-state functional magnetic resonance imaging was used to test the seed-based functional connectivity in 181 healthy subjects.
Behavioral results revealed that more frequent reappraisal was associated with an enhanced ability to control negative memories. Resting-state seed-based functional connectivity showed that habitual use of reappraisal was positively related to the strength of functional connectivity between the right ventrolateral prefrontal cortex (VLPFC) and right insula. Most importantly, this functional connectivity mediated the effect of habitual use of reappraisal on control over negative memories.
Present results mainly showed the habitual use of reappraisal was related with MC ability in negative items. Future study could further explore the relationship between MC ability of different categories of negative emotional memories and other kinds of ER strategies.
Our results support the notion that reappraisal provides opportunities for individuals to practice and enhance inhibitory control-a relationship underpinned by connectivity between the right VLPFC and right insula.
记忆控制（MC）能力对人们的身心健康至关重要。先前的研究从概念上证明了 MC 能力与再评价密切相关。然而，支持这种关系的实验证据有限。因此，在本研究中，我们通过行为和大脑两个方面，研究了 MC 和再评价之间的关系。
使用情绪调节问卷评估再评价的习惯使用，通过定向遗忘任务测量记忆控制能力。在 181 名健康受试者中使用静息态功能磁共振成像来测试基于种子的功能连接。
行为结果表明，更频繁地使用再评价与增强控制负面记忆的能力有关。静息态种子的功能连接显示，习惯性使用再评价与右侧腹外侧前额叶皮层（VLPFC）和右侧岛叶之间功能连接的强度呈正相关。最重要的是，这种功能连接介导了习惯性使用再评价对负面记忆控制的影响。
目前的结果主要表明习惯性使用再评价与负面项目的 MC 能力有关。未来的研究可以进一步探索不同类别的负性情绪记忆和其他类型的 ER 策略的 MC 能力之间的关系。
我们的研究结果支持这样一种观点，即再评价为个体提供了练习和增强抑制控制的机会——这种关系是由右侧 VLPFC 和右侧岛叶之间的连接支持的。
