Brooding rumination is associated with depressed mood, increased negative affect, prolonged anger and inhibited cardiovascular (CV) recovery. Distraction from rumination on a stressful interpersonal encounter is associated with faster CV recovery and decreased negative affect. Studies have suggested that a concurrent visuospatial (VS) task inhibits the maintenance of imagery associated with the perseveration of intrusive negative memories. 120 healthy participants were recruited for the study. As an analogue of repeated angry rumination, the authors explored the effects of repeated visual recall of a provocative confederate and the subsequent impact of two visuospatial (VS) distraction tasks on negative affect, blood pressure (BP) and heart rate (HR). Repeated recall of the provocation generated repeatedly elevated HR with a cumulative trend that may have CV disease risk implications for chronic ruminators. VS distraction did not aid recovery compared with the Control task.
反复沉思与情绪低落、负面影响增加、愤怒持续时间延长以及心血管（CV）恢复受抑制有关。在人际压力情境中，从反复沉思中分散注意力与更快的心血管恢复和负面影响减少有关。研究表明，同时进行的视觉空间（VS）任务会抑制与侵入性负面记忆持续存在相关的意象维持。该研究招募了120名健康参与者。作为反复愤怒沉思的模拟，作者探讨了反复视觉回忆挑衅性同伴的影响，以及随后两个视觉空间（VS）分心任务对负面影响、血压（BP）和心率（HR）的影响。反复回忆挑衅会使心率反复升高，呈累积趋势，这可能对慢性沉思者有患心血管疾病的风险影响。与对照任务相比，视觉空间分心无助于恢复。
