自我报告是衡量疼痛的黄金标准。然而，关于疼痛的决定在个体内部和个体之间存在很大差异。我们测量了自我报告的疼痛是否伴随着元认知和信心的变化，类似于其他模式的感知决策。80名健康志愿者经历了急性热痛，并在连续视觉模拟量表上提供了疼痛评分和信心判断。我们调查了在疼痛评分时眼睛的注视和反应时间是否可以作为自信的内隐标记。信心在不同的试验中有所不同，信心的增加与更快的疼痛评分反应时间有关。自信和注视之间的联系在个体之间是不同的，这是个体对温度和疼痛之间联系的可靠性的函数。综上所述，这项工作表明个体可以提供对疼痛的元认知判断，并将对感知决策信心的研究扩展到疼痛。
Self-report is the gold standard for measuring pain. However, decisions about pain can vary substantially within and between individuals. We measured whether self-reported pain is accompanied by metacognition and variations in confidence, similar to perceptual decision-making in other modalities. Eighty healthy volunteers underwent acute thermal pain and provided pain ratings followed by confidence judgments on continuous visual analogue scales. We investigated whether eye fixations and reaction time during pain rating might serve as implicit markers of confidence. Confidence varied across trials and increased confidence was associated with faster pain rating reaction times. The association between confidence and fixations varied across individuals as a function of the reliability of individuals’ association between temperature and pain. Taken together, this work indicates that individuals can provide metacognitive judgments of pain and extends research on confidence in perceptual decision-making to pain.
