After making a lineup identification, eyewitnesses remember being more confident in their identification and having a better view of the initial crime if they are told they correctly identified the suspect compared to witnesses not given this feedback. The present studies investigated whether this effect of feedback occurs similarly when witnesses report their confidence numerically and when they report their confidence in their own words. Across three studies, participants (N = 1396) watched a mock crime video, received either confirmatory feedback or not, and reported their confidence in words, numbers, or both words and numbers. Results showed a significant effect of feedback on both confidence and witnessed experience in all confidence conditions. This effect occurred with both biased and unbiased lineup instructions and with both target-present and target-absent lineups. The results advance discussions about the best means for reporting confidence in the field.

“用你自己的话来说，你有多确定？” 识别后的反馈扭曲了目击者信心的口头和数字表达

在进行阵容识别后，目击者记得如果被告知他们正确识别了嫌疑人，与未提供此反馈的证人相比，他们对自己的识别更有信心，并且可以更好地了解最初的犯罪行为。目前的研究调查了当证人以数字方式报告他们的信心时以及当他们用自己的话报告他们的信心时，反馈的这种影响是否会发生类似的情况。在三项研究中，参与者（N = 1396) 观看了一个模拟犯罪视频，无论是否收到确认反馈，并报告他们对文字、数字或文字和数字的信心。结果表明，在所有信心条件下，反馈对信心和目击经验都有显着影响。这种效果发生在有偏见和无偏见的阵容指令中，以及存在目标和不存在目标的阵容中。结果促进了关于报告该领域信心的最佳方法的讨论。
