在回答事实性问题时，说话者可以使用诸如填充词（“呃”）、升调轮廓或明显的面部表情等韵律线索来表明他们是否不确定答案的正确性。事实证明，根据这些线索，观察者可以对说话者的置信水平做出充分的估计，但尚不清楚这些线索中哪一个对感知的影响最大。为了找出上述三个线索的相对强度，进行了一项新颖的感知实验，其中答案被人为地操纵，以便参与者可以判断感兴趣线索的所有可能组合。结果表明，虽然所有三个因素对感知结果都有显着影响，但这种影响迄今为止对面部表情的影响最大。
When answering factual questions, speakers can signal whether they are uncertain about the correctness of their answer using prosodic cues such as fillers (“uh”), a rising intonation contour or a marked facial expression. It has been shown that on the basis of such cues, observers can make adequate estimates about the speaker’s level of confidence, but it is unclear which of these cues have the largest impact on perception. To find the relative strength of the three aforementioned cues, a novel perception experiment was performed in which answers were artificially manipulated in such a way that all possible combinations of the cues of interest could be judged by participants. Results showed that while all three factors had a significant influence on the perception results, this effect was by far the largest for facial expressions.
