摘　　要：积极认知重评的情绪调节功能已被广为证实,但该策略对情绪相关行为是否具有类似的调节作用并不清楚。考虑到虚假舆情信息的传播管控在网络安全领域的重要性,本研究通过两个实验,从行为和电生理层面考察积极认知重评在全貌未知(对发生原因不了解)负性信息传播中的调控作用及其作用机制。结果表明:(1)被试在进行积极认知重评后对全貌未知负性信息的负性情绪体验降低,道德判断标准放宽,转发行为减少。(2)积极认知重评降低了被试观看负性信息时其情绪注意相关的枕颞区早期后部负波(Early Posterior Negativity,EPN)波幅。中介分析进一步揭示,EPN在积极认知重评减少被试转发意愿和转发行为中发挥中介作用。该结果提示,积极认知重评策略能通过降低个体对情绪信息的注意偏向,从而有效减少个体对全貌未知负性信息的转发行为。The surge in popularity of social media platforms,such as Sina Weibo,has made retweet a significant means of online information dissemination,yet concurrently led to the rampant spread of false information,resulting in frequent network contingencies.Therefore,understanding the mechanisms,influencing factors,and possible interventions for the dissemination of negative information with unknown contexts is imperative.Despite this importance,few studies have examined the role of emotional regulation in curbing the spread of such information from the perspective of individual retweet behavior.This study addresses this gap by conducting two experiments that explore the effects and underlying mechanisms of emotions and emotion regulation strategies,specifically positive cognitive reappraisal(considering positive aspects of the event),on the propagation of such ambiguous information at both behavioral and electrophysiological levels.Utilizing a mixed factorial design with 2(Information Type:Neutral vs Negative)×2(Regulation Strategy:Positive Cognitive Reappraisal vs Observation),participants were divided into Reappraisal and Observation groups(control group).In the experimental procedure,a fixation point was initially presented,followed by randomly displayed emotionally-laden event images(neutral faces combined with neutral/negative information),which had been pre-assessed.Participants were instructed to either simply immerse themselves in observing the images(Observation group)or to engage in both observation and positive cognitive reappraisal(Reappraisal group),after which they rated their emotional experiences,moral judgments,retweet willingness and retweet behavior.Experiment 1 included 71 participants(mean age 20.16±1.85 years);the Reappraisal group consisted of 35 participants(14 males,22 females),while the Observation group comprised 36 participants(11 males,24 females).Experiment 2 involved 44 participants(mean age 20.04±1.83 years),with 22 in each group.Building upon Experiment 1,this second experiment incorp
