Could social context variables prime complex decisions? Could top-down processes impair this priming susceptibility? Complex decisions have been mainly studied from economic and moral perspectives, and Dual Process Theories provide evidence of how these processes could be affected. To address these issues from a political perspective, online experiments were conducted. Participants (n = 252) were asked to choose a face from 4 options, each associated with different frequencies (repetition priming) or with phrases with different emotional valence (emotional priming), for an unspecified task (UST group) or an important task (IMT group). The most repeated face was chosen most in the UST group, and was associated with lower response times. Positive faces were equally chosen by both groups. To compare results in a more ecological situation, a social study was conducted during the 2019 Argentine Presidential Election, including online surveys (n = 3673) and analysis of news media mentioning candidates. The familiarity and trust to each candidate explained the voting-probability for most of them, as well as correlated with their frequency of mentions in the news, their positive associations, and election results. Our results suggest complex decision-making is susceptible to priming, depending on top-down modulation.
社会语境变量能否引发复杂决策？自上而下的过程是否会损害这种启动易感性？复杂决策主要从经济和道德角度进行研究，而双重过程理论提供了证据，证明这些过程可能会受到影响。为了从政治角度解决这些问题，进行了在线实验。要求参与者（n=252）从 4 个选项中选择一张脸，每个选项都与不同的频率（重复启动）或不同情感效价的短语（情绪启动）相关联，用于未指定的任务（UST 组）或重要任务（IMT 组）。UST 组中选择最常出现的面孔最多，且与响应时间更短相关。两个组都同样选择了积极的面孔。为了在更具生态性的情况下比较结果，在 2019 年阿根廷总统选举期间进行了一项社会研究，包括在线调查（n=3673）和对提及候选人的新闻媒体的分析。对每位候选人的熟悉度和信任度解释了他们中的大多数人的投票可能性，这与他们在新闻中的提及频率、他们的积极关联以及选举结果相关。我们的结果表明，复杂决策易受启动影响，这取决于自上而下的调节。
