Deception Cues During High-Risk Situations: 911 Homicide Calls
研究了成年人在拨打911凶杀电话时，欺骗者与诚实者表现出的不同线索，发现欺骗者更易出现情绪化、叙述混乱等特征，并验证了Q分类法在识别欺骗中的有效性。
During everyday interactions, cues tend to be weakly related to deception. However, there are theoretical reasons to suspect that such cues will be more prominent during high-risk interactions. The current study explored deception cues during one particular high-risk interaction—911 homicide calls placed by adults. In Sample 1, judges coded 911 homicide calls ( n = 82) by Q-sorting 86 cues. Results indicated that deceptive callers tended to display emotional cues (e.g., self-dramatizing, moody, worried, emotional, nervous), appeared overwhelmed, and related narratives that lacked structure, clarity, and focus. Judges coded a separate sample of 911 calls ( n = 64), and deception scores were computed using a template-matching approach based on the findings from Sample 1. Results indicated that deceptive 911 callers had higher deception scores than honest callers. The effect sizes yielded in this study highlight the relevance of deception cues during high-risk interactions and the usefulness of the person-centered Q-sort method.
