正念训练对冲动性不同要素的影响：基于双加工理论

正念是指对当下身心体验不带有评判地觉察。基于双加工理论,以正念为核心的训练对个体冲动性不同要素均具有明显干预效果。一方面,有助于降低因情感系统引发的冲动驱力：通过调整个体的奖赏评估与预期,缓和诱发冲动的压力与负性情绪反应,减弱自动化反应的联结和强度;另一方面,提升个体由认知控制系统调节的冲动控制力：增强个体的认知控制和行为抑制能力。由于冲动性驱动因素和控制因素二者加工时序的先后差异和作用方向对抗性特点,正念训练促进两类要素的积极交互影响,缩小冲动性“驱动”与“控制”力量之间的不平衡,为个体更好地回应自身反应与外界刺激提供了有利缓冲,是降低个体冲动性的有效干预手段。

The effects of mindfulness-based interventions on different components of impulsivity: From the perspective of dual-process theories

Impulsivity is referred as a predisposition to act rashly on one’s first thoughts, which is usually characterized by little forethought, reflection, or consideration of the consequences of an action. According to the dual-process framework, components of impulsivity can be classified into affective impulsivity and action/cognitive impulsivity which then integrate into what is called a drive - control construct. These two types of impulsivities are dominated by the socioemotional system (driving force) and the cognitive control system (controlling force) respectively. The dual-process theories offer a novel explanation for the underlying mechanisms of impulsivity, and Mindfulness practices is a type of method that can effectively regulate impulsivity and be well explained by this theory framework.
