The aim of this study is to determine whether the presence of the interjection 'um' can distinguish between the deceptive and truthful speech of individuals who are practised in the art of impression management. A total of 50 truthful and 61 deceptive statements were extracted from the speech of celebrities participating in a televised comedy panel show where celebrity guests try to convince an opposing team of their truthfulness. Participants' use of 'um' (measured as a percentage of the total word count of each statement) was analysed. The results show that, on average, 'um' was used almost three times as often in the speakers' true statements compared to their false ones. A discriminant analysis revealed that the presence of 'um' is more effective than human judgement alone in determining veracity. These findings suggest that the presence of the filler 'um' in speech is useful in the identification of true versus false oral statements.
本研究的目的是确定感叹词“嗯”的出现是否能够区分擅长印象管理技巧的个体的欺骗性言语和真实言语。从参加电视喜剧小组节目的名人讲话中总共提取了50条真实陈述和61条欺骗性陈述，在该节目中名人嘉宾试图让对方团队相信他们所言属实。分析了参与者对“嗯”的使用情况（以每条陈述的总字数百分比来衡量）。结果表明，平均而言，说话者在真实陈述中使用“嗯”的频率几乎是虚假陈述中的三倍。判别分析显示，在确定真实性方面，“嗯”的出现比单纯依靠人类判断更有效。这些发现表明，言语中填充词“嗯”的出现有助于识别口头陈述的真假。
