Abstract

A significant body of research has investigated potential correlates of deception and bodily behavior. The vast majority of these studies consider discrete, subjectively coded bodily movements such as specific hand or head gestures. Such studies fail to consider quantitative aspects of body movement such as the precise movement direction, magnitude and timing. In this paper, we employ an innovative data mining approach to systematically study bodily correlates of deception. We re-analyze motion capture data from a previously published deception study, and experiment with different data coding options. We report how deception detection rates are affected by variables such as body part, the coding of the pose and movement, the length of the observation, and the amount of measurement noise. Our results demonstrate the feasibility of a data mining approach, with detection rates above 65%, significantly outperforming human judgement (52.80%). Owing to the systematic analysis, our analyses allow for an understanding of the importance of various coding factor. Moreover, we can reconcile seemingly discrepant findings in previous research. Our approach highlights the merits of data-driven research to support the validation and development of deception theory.

挖掘欺骗的身体线索

摘要大量研究调查了欺骗和身体行为的潜在相关性。这些研究绝大多数考虑的是离散的、主观编码的肢体动作，如特定的手势或头部动作。这些研究没有考虑身体动作的定量方面，如精确的动作方向、幅度和时间。在本文中，我们采用了一种创新的数据挖掘方法来系统地研究欺骗行为的身体相关因素。我们重新分析了之前发表的一项欺骗研究中的动作捕捉数据，并试验了不同的数据编码选项。我们报告了欺骗检测率如何受到身体部位、姿势和动作编码、观察长度以及测量噪音量等变量的影响。我们的结果证明了数据挖掘方法的可行性，其检测率超过 65%，明显优于人类判断（52.80%）。通过系统分析，我们可以了解各种编码因素的重要性。此外，我们还能调和以往研究中看似不一致的发现。我们的方法凸显了数据驱动研究在支持欺骗理论的验证和发展方面的优势。
