This study explored a psychophysiological measure, Resting Heart Rate (RHR), as a predicator of the ability to detect lies. RHR was recorded for 1min and followed by a deception detection task in which participants were required to judge 24 videos of people describing a real-life event (50% truthful, 50% deceptive). Multiple regression analyses showed that, among other individual characteristics, only RHR predicted the ability to distinguish truth from lies. Importantly, the prediction was negative. This result suggests that the higher the RHR, the worse the detection of lies. Since the RHR is considered to be a physiological trait indexing autonomous arousal, and since high-arousal states can lead to restricted attentional resources, we suggest that limited selection and utilization of cues due to restricted attention is the reason why higher RHR leads to poor deception detection.
本研究探索了一种心理生理测量指标，即静息心率（RHR），作为检测谎言能力的预测指标。记录了 1 分钟的 RHR，随后进行了欺骗检测任务，要求参与者判断 24 段描述真实生活事件的视频（50%真实，50%欺骗）。多元回归分析显示，在其他个体特征中，只有 RHR 预测了区分真假的能力。重要的是，这种预测是负面的。这一结果表明，RHR 越高，对谎言的检测能力越差。由于 RHR 被认为是一个反映自主唤醒的生理特征，并且由于高唤醒状态会导致注意力资源受限，因此我们认为，由于注意力受限导致的线索选择和利用受限，是导致 RHR 较高的人欺骗检测能力较差的原因。
