有效引导注意力的能力是调节情绪的一个重要方面，也是正念的一个组成部分。正念练习已经被确定为治疗精神和身体疾病的有效干预措施；然而，正念的潜在神经机制以及它们与情绪处理的关系还没有深入探讨。目前的研究使用了受试者内部的重复测量设计，以检查集中的呼吸，一种短暂的正念诱导，是否可以相对于控制条件，在情绪图像处理过程中调节事件相关电位(ERPs)。我们将处理积极、消极和中性图像的ERP测量(P300和晚期正向电位-LPP)与状态和特质正念测量相关联。总体而言，短暂正念诱导条件并不影响反映情绪处理的事件相关电位；然而，在短暂正念诱导条件下，那些报告在观看图像后感觉更偏心的参与者(多伦多正念量表的一个子量表)对负面图像的P300反应比对中性图像的反应减少。
The ability to effectively direct one’s attention is an important aspect of regulating emotions and a component of mindfulness. Mindfulness practices have been established as effective interventions for mental and physical illness; however, the underlying neural mechanisms of mindfulness and how they relate to emotional processing have not been explored in depth. The current study used a within-subjects repeated measures design to examine if focused breathing, a brief mindfulness induction, could modulate event-related potentials (ERPs) during emotional image processing relative to a control condition. We related ERP measures of processing positive, negative, and neutral images (the P300 and late positive potential – LPP) to state and trait mindfulness measures. Overall, the brief mindfulness induction condition did not influence ERPs reflecting emotional processing; however, in the brief mindfulness induction condition, those participants who reported feeling more decentered (a subscale of the Toronto Mindfulness Scale) after viewing the images had reduced P300 responses to negative versus neutral images.
