摘要：

自动情绪调节无需意识决定、注意加工及有意控制, 改变着情绪轨迹。迄今为止, 研究仅限于证实其确能低耗高效地改变情绪过程, 尚未对其如何改变情绪过程进行研究。以自动情绪调节的神经机制作为研究对象具有可操作性, 可从行为和心理生理层面, 对自动情绪调节改变情绪过程的机制进行实验研究。研究问题包括：1)通过EEG技术检验自动情绪调节是否影响预备阶段行为反应倾向; 2)自动情绪调节对注意的注意觉醒、注意朝向和注意执行三个阶段的作用机制; 3)自动情绪调节对评价和反应的作用机制; 4)自动情绪调节的可塑性在脑活动上的体现。最终确定自动情绪调节的加工规律, 构建其预备-注意-评价-反应模型, 并为有效控制情绪紊乱和研究出高效的情绪调节干预方案提供理论和实证依据。

Abstract:

Automatic emotion regulation (AER) is defined as any process that modifies any aspect of one's emotions without the need for conscious supervision or explicit intentions and without engaging in deliberate control. Research has gathered ample evidence that AER is effective in down-regulating negative emotions with low cost. The mechanism underlying AER, however, has not been studied. In four studies, we aim to examine the neural mechanism of AER, and to anchor the place where AER starts to affect emotion processing. Study 1 examines whether AER affect behavior intendancy in preparatory phase by recording EEG and analyzing AER's effect on frontal alpha laterality. In study 2 and study 3, we examine whether AER affect selective attention of facial expressions as well as the evaluation and behavior reaction stage. Furthermore, in study 4, a training of regulation goal was conducted to explore the plasticity of brain activity in AER. We expect to get a preparation-attention-evaluation-reaction model to explain the mechanism of AER based on the four studies, so as to provide theoretical and empirical evidences to control and intervene in emotion disorder.
