In popular belief, emotions are regarded as deeply subjective and thus as lacking truth value. Is this reflected at the behavioral or brain level? This work compared counter-normative emotion reports with perceptual-decision errors. Participants (university students; = 29, 16, 40, and 60 in Experiments 1-4, respectively) were given trials comprising two tasks and were asked to (a) report their pleasant or unpleasant feelings in response to emotion-invoking pictures (emotion report) and (b) indicate the gender of faces (perceptual decision). Focusing on classical error markers, we found that the results of both tasks indicated (a) post-error slowing, (b) speed/accuracy trade-offs, (c) a heavier right tail of the reaction time distribution for errors or counter-normative responses relative to correct or normative responses, and (d) inconclusive evidence for error-related negativity in electroencephalograms. These results suggest that at both the behavioral and the brain levels, the experience of reporting counter-normative emotions is remarkably similar to that accompanying perceptual-decision errors.
在大众的观念中，情绪被认为是非常主观的，因此缺乏真理价值。这种观点是否在行为或大脑层面上有所体现呢？本研究将反常规的情绪报告与知觉决策错误进行了比较。参与者（大学生；实验 1-4 中分别有 29、16、40 和 60 名参与者）接受了包含两个任务的实验，要求他们(a)对唤起情绪的图片做出愉快或不愉快的感觉报告（情绪报告），以及(b)指出人脸的性别（知觉决策）。我们重点关注经典的错误标记，发现两个任务的结果都表明(a)错误后减速，(b)速度/准确性权衡，(c)相对于正确或规范反应，错误或反常规反应的反应时分布的右尾更重，以及(d)脑电图中错误相关负波的证据不充分。这些结果表明，在行为和大脑层面上，报告反常规情绪的体验与伴随知觉决策错误的体验非常相似。
