According to expectancy violations theory, displays of behavior considered “unusual” during an interaction will trigger scrutiny of an individual. Such scrutiny may be detrimental in forensic contexts, where deception detection is emphasized. Autistic individuals, in particular, may be scrutinized unfavorably given unusual nonverbal behavior associated with the condition. Across two experiments using between-subjects’ designs, participants (overall N = 3,342) watched a scripted police-suspect interrogation, randomized to view the suspect display autism-related behaviors or none of those behaviors. Autistic behavior biased evaluations of deception and guilt as a function of violating individual behavioral expectations, regardless of whether decisive or ambiguous evidence framed the suspect as guilty or innocent. Promisingly, however, providing an autism information card attenuated such evaluations. Our research extends expectancy violations theory, advances understanding of determinants of forensic judgments, highlights important applied implications for nonverbal behavior displays in the justice system and recommends methods to protect against bias.

反对在法医环境中表现出自闭症特征行为的个人的偏见判断

根据违反期望理论，在互动中表现出被认为“不寻常”的行为将引发对个人的审查。在强调欺骗检测的法医环境中，这种审查可能是有害的。尤其是自闭症患者，可能会因为与该病症相关的不寻常的非语言行为而受到不利的审查。在使用受试者之间设计的两个实验中，参与者（总体 N = 3,342）观看了一个脚本化的警察嫌疑人审讯，随机查看嫌疑人表现出与自闭症相关的行为或没有这些行为。自闭症行为对欺骗和内疚的偏见评估是违反个人行为期望的函数，无论决定性或模棱两可的证据是否将嫌疑人定为有罪或无罪。然而，令人欣慰的是，提供自闭症信息卡减弱了这种评估。我们的研究扩展了预期违反理论，促进了对法医判断决定因素的理解，突出了司法系统中非语言行为表现的重要应用意义，并推荐了防止偏见的方法。
