最近的证据表明，反射（即，距离-为什么），与反刍（即，沉浸式为什么），负面记忆的处理与负面影响的减少有关。本研究扩展了这条线的工作，通过检查这两种处理条件对双相情感障碍（BD; n = 27）和健康对照组（CT; n = 27）的人之间的积极记忆的影响。在一段休息的基线期后，参与者被要求回忆一段快乐的自传体记忆。采用受试者内设计，要求参与者在两种不同的实验条件下（反思，沉思）处理快乐记忆，同时测量他们的经验，行为和自主反应。与假设一致，与所有参与者的沉思处理相比，反思处理与自我报告的积极影响，积极思想和心率较低相关。当当前症状得到控制时，BD参与者报告了相对于CT参与者的更大的积极影响。需要进行前瞻性研究，以测试积极情绪的处理在多大程度上有助于双相情感障碍的症状过程。(C)2009爱思唯尔有限公司版权所有
Recent evidence suggests that reflective (i.e., distanced-why), as compared to ruminative (i.e., immersed-why), processing of negative memories is associated with reductions in negative affect. The present study extended this line of work by examining the effect of these two processing conditions on positive memories among persons with bipolar disorder (BD; n = 27) and a healthy control group (CT; n = 27). After a resting baseline period, participants were instructed to recall a happy autobiographical memory. Using a within-subjects design, participants were asked to process the happy memory in two different experimental conditions (reflective, ruminative) while their experiential, behavioral, and autonomic responses were measured. Consistent with hypotheses, reflective processing was associated with lower self-reported positive affect, positive thoughts, and heart rate compared to ruminative processing for all participants. When Current symptoms were controlled for, BD participants reported greater positive affect across both conditions relative to CT participants. Prospective studies are needed to test the extent to which processing of positive emotion contributes to the course of symptoms in bipolar disorder. (C) 2009 Elsevier Ltd. All rights reserved
