Positive urgency, the tendency to respond impulsively to positive affective states, has been linked to many psychopathologies, but little is known about mechanisms underpinning this form of impulsivity. We examined whether the Positive Urgency Measure (PUM) related to higher scores on performance-based measures of impulsivity and cognitive control that were administered after a positive mood induction. Undergraduates (n = 112) completed the self-report PUM, several positive mood inductions, and behavioral measures of impulsivity and cognitive control. PUM scores were significantly related to poor performance on the antisaccade task, a measure of prepotent response inhibition, but not to other performance measures. Together with existing literature, findings implicate deficits in response inhibition as one mechanism involved in emotion-related impulsivity. (PsycINFO Database Record
积极紧迫性，即对积极情感状态做出冲动反应的倾向，已与多种精神病理学相关联，但对于支撑这种冲动形式的机制却知之甚少。我们研究了积极紧迫性量表（PUM）是否与积极情绪诱导后进行的基于表现的冲动性和认知控制测量中的较高分数相关。本科生（n = 112）完成了自我报告的PUM、几种积极情绪诱导以及冲动性和认知控制的行为测量。PUM分数与反扫视任务（一种优势反应抑制的测量方法）中的不佳表现显著相关，但与其他表现测量无关。结合现有文献，研究结果表明反应抑制缺陷是与情绪相关的冲动性所涉及的一种机制。（PsycINFO数据库记录）
