Self-efficacy is a subjective belief that depends on self-related past experience, and is a strong predictor for individual future performance. To the aim of promoting one’s future performance, it is necessary to gain better knowledge of it’s cognitive process and brain mechanism. The present research sought to investigate the functional connectivity basis of self-efficacy by using the resting-state functional magnetic resonance imaging data of a large sample of young adults (536 participants). Multiple regression analysis was performed to examine the relationship between self-efficacy integrated score and brain functional connectivity measures. Gender, age, mean framewise displacement and grey matter volume were used as nuisance covariates. The whole-brain analysis revealed an association between self-efficacy and the functional connectivity of several regions within the default mode network. These regions included the right anterior cingulate cortex, the left posterior cingulate cortex/precuneus and bilateral parahippocampal cortex. Our findings suggest that the default mode network plays a crucial role in self-efficacy, and hold the view that episodic memory and self-related processing have influence on self-efficacy.

自我效能感是一种主观信念，它依赖于与自我相关的过去经历，是个人未来表现的有力预测指标。为了提高一个人的未来表现，有必要更好地了解它的认知过程和大脑机制。本研究试图通过使用大量年轻人（536 名参与者）样本的静息状态功能磁共振成像数据来研究自我效能的功能连接基础。进行多元回归分析以检查自我效能综合评分与大脑功能连接测量之间的关系。性别、年龄、平均帧位移和灰质体积被用作令人讨厌的协变量。全脑分析揭示了自我效能与默认模式网络中几个区域的功能连接之间的关联。这些区域包括右前扣带皮层、左后扣带皮层/楔前叶和双侧海马旁皮质。我们的研究结果表明，默认模式网络在自我效能感中起着至关重要的作用，并认为情景记忆和自我相关加工对自我效能感有影响。
