Abstract

ABSTRACT Objective Unusual behaviours are commonly perceived to indicate deception and low credibility. However, they may also characterise individuals with certain mental health or developmental conditions, thus making those individuals vulnerable to negative judgements. We examined the effect of four behaviours – gaze aversion, body movements, monologuing, and flat affect – on judgements of deception and credibility. Method In an online experiment, we presented participants (N = 392) with videos of actors being interviewed about their involvement in stealing money. In each video, the actor was either instructed to display one of the four behaviours or was not instructed to display any particular behaviour (control condition). Participants were then asked to provide ratings of perceived deception and credibility. Results There were significant effects of body movements and monologuing on perceived deception, and significant effects of monologuing and flat affect on the specific credibility dimension of perceived caring. Gaze aversion did not have a statistically significant effect on perceived deception or credibility. Conclusion Body movements, monologuing, and flat affect negatively affected deception and credibility judgements. Populations who commonly display these behaviours, such as individuals with certain mental health or developmental conditions, may be vulnerable to unfair evaluations in the criminal justice system. KEY POINTS What is already known about this topic: Based on self-report measures, unusual behaviours are widely believed to be indicators of deception and low credibility. There is no empirical evidence that behavioural cues are reliable indicators of deception or credibility. Gaze aversion, repetitive body movements, monologuing, and flat affect are common among individuals with certain disabilities and mental health conditions. What this paper adds: This study provides experimental support for the effect of repetitive body movements, monologuing, and flat affect on judgements of deception and credibility. Individuals who present with repetitive body movements, monologuing, or flat affect due to a disability or mental health condition may be subject to unjust evaluations of deception and credibility. There is an important need for further research on how individuals with disabilities and mental health conditions are perceived in the criminal justice system.
在某些精神健康状况下发现的非典型行为对欺骗和可信度的判断产生负面影响
【摘要】目的不寻常的行为通常被认为是欺骗和低可信度的表现。然而,它们也可能是具有某些心理健康或发育状况的个体的特征,从而使这些个体容易受到负面判断的影响。我们研究了四种行为——厌恶凝视、肢体动作、独白和平淡情绪——对欺骗和可信度判断的影响。方法在一项在线实验中,我们向参与者(N = 392)提供了演员被采访的视频,内容是他们参与偷钱。在每个视频中,演员要么被指示表现出四种行为中的一种,要么没有被指示表现出任何特定的行为(控制条件)。然后,参与者被要求对感知到的欺骗和可信度进行评分。结果肢体动作和独白对感知欺骗有显著影响,而独白和平淡对感知关怀的具体可信度维度有显著影响。凝视厌恶对感知欺骗或可信度没有统计学上的显著影响。结论肢体动作、独白和平面对欺骗和可信度判断有负向影响。通常表现出这些行为的人群,例如具有某些精神健康或发育状况的个人,可能容易受到刑事司法系统的不公正评价。关于这个话题的已知情况:基于自我报告的测量,不寻常的行为被广泛认为是欺骗和低可信度的指标。没有经验证据表明行为线索是欺骗或可信度的可靠指标。凝视厌恶、重复的身体动作、独白和扁平情绪在某些残疾和精神健康状况的人群中很常见。本文补充内容:本研究为重复肢体动作、独白和平面影响对欺骗和可信度判断的影响提供了实验支持。由于残疾或精神健康状况而出现重复身体动作、独白或平淡情绪的个人可能会受到对欺骗和可信度的不公正评估。迫切需要进一步研究刑事司法系统如何看待残疾人和有精神健康状况的人。
