In the current study, we report on an experiment examining whether functional magnetic resonance imaging (fMRI) lie detection evidence would influence potential jurors' assessment of guilt in a criminal trial. Potential jurors (N = 330) read a vignette summarizing a trial, with some versions of the vignette including lie detection evidence indicating that the defendant was lying about having committed the crime. Lie detector evidence was based on evidence from the polygraph, fMRI (functional brain imaging), or thermal facial imaging. Results showed that fMRI lie detection evidence led to more guilty verdicts than lie detection evidence based on polygraph evidence, thermal facial imaging, or a control condition that did not include lie detection evidence. However, when the validity of the fMRI lie detection evidence was called into question on cross-examination, guilty verdicts were reduced to the level of the control condition. These results provide important information about the influence of lie detection evidence in legal settings.
在当前的研究中，我们报告了一项实验，该实验旨在检验功能磁共振成像（fMRI）测谎证据是否会影响刑事审判中潜在陪审员对被告有罪的评估。潜在陪审员（N=330）阅读了一个摘要总结了一个审判的案例，其中一些版本的案例包括测谎证据表明被告对犯罪撒谎。测谎证据基于多项生理记录仪、fMRI（功能性大脑成像）或热面部成像的证据。结果表明，fMRI 测谎证据比基于多项生理记录仪证据、热面部成像证据或不包括测谎证据的对照条件的测谎证据导致更多的有罪判决。然而，当在交叉盘问中对 fMRI 测谎证据的有效性提出质疑时，有罪判决减少到对照条件的水平。这些结果提供了关于测谎证据在法律环境中影响的重要信息。
