The primary goal of the proposed research is to understand the basic cognitive mechanisms underlying rumination a perseverative and passive cognitive style characterized by difficulty disengaging from thoughts about negative emotions and problems. Although rumination is a pervasive and universal phenomenon, the cognitive components that underlie it are not yet fully understood. Contemporary conceptualizations of rumination maintain that negative cognitive control biases are the primary mechanism underlying rumination. Cognitive control refers to people's ability to control the contents of working memory by overriding automatic responses or by inhibiting irrelevant or previously relevant material. Importantly, cognitive control is not a unitary construct. It consists of three related cognitive components: shifting, inhibiting, and updating. Surprisingly, rumination theory and research have overlooked the complexity of cognitive control biases, resulting in imprecise and over-general models of rumination. The program of research proposed here aims to identify the cognitive mechanisms underlying rumination by conducting a series of studies that test the components of cognitive control that predict rumination across various contexts (Objective 1) and to characterize the physiological mechanisms through which different aspects of cognitive control affect rumination (Objective 2). The proposed series of experimental and real-world studies are designed to alter our understanding of the mechanisms underlying rumination. Findings from this research are intended to create a more complete and accurate theoretical model of rumination by taking into account the complexity of cognitive control biases.

这项研究的主要目的是了解沉思背后的基本认知机制，沉思是一种坚持不懈和被动的认知方式，其特征是难以摆脱对负面情绪和问题的思考。虽然沉思是一种普遍而普遍的现象，但其背后的认知成分还没有完全被理解。当代关于反思冥想的概念化观点认为，消极的认知控制偏差是反思冥想的主要机制。认知控制指的是人们通过压倒自动反应或抑制无关或先前相关的材料来控制工作记忆内容的能力。重要的是，认知控制不是一个单一的结构。它由三个相关的认知成分组成：移位、抑制和更新。令人惊讶的是，沉思理论和研究忽略了认知控制偏差的复杂性，导致了沉思的不精确和过于笼统的模型。本文提出的研究方案旨在通过进行一系列研究来确定沉思背后的认知机制，这些研究测试认知控制的组成部分，预测不同背景下的沉思(目标1)，并表征认知控制的不同方面影响沉思的生理机制(目标2)。拟议中的一系列实验和现实世界研究旨在改变我们对沉思背后的机制的理解。本研究的发现旨在通过考虑认知控制偏差的复杂性来创建一个更完整、更准确的沉思理论模型。
