背景：准确检测欺骗的能力目前非常有限。通过测量一个人说谎的大脑相关性，可能会更准确地检测出欺骗行为。此外，研究欺骗的神经回路的方法可能提供一个独特的机会来测试欺骗是一个突出组成部分的人的神经回路（即，品行障碍反社会人格障碍等）。我们使用功能性磁共振成像（fMRI）显示，当受试者欺骗时，特定区域被重复激活。受试者参加了一个模拟犯罪偷戒指或手表。在接受功能性磁共振成像时，受试者否认拿过任何一件物品，因此在一些反应中说了实话，在另一些反应中撒谎。模型制作小组（MBG，n = 30）用于开发分析方法，并随后将该方法应用于独立的模型测试组结果：MBG组和MTG组分别有93%和90%的被试能正确区分真实性和欺骗性反应，并能正确识别被盗物品。这是第一项使用fMRI来检测个人层面的欺骗行为的研究。需要进一步的工作来确定这种技术是否适用于不同的环境和人群。
Background: The ability to accurately detect deception is presently very limited. Detecting deception might be more accurately achieved by measuring the brain correlates of lying in an individual. In addition, a method to investigate the neurocircuitry of deception might provide a unique opportunity to test the neurocircuitry of persons in whom deception is a prominent component (i.e., conduct disorder. antisocial personality disorder, etc,).Methods: In this study. we used functional magnetic resonance imaging (fMRI) to show that specific regions were reproducibly activated when subjects deceived. Subjects participated in a mock crime stealing either a ring or a watch. While undergoing an fMRI, the subjects denied taking either object, thus telling the truth with some responses, and lying with others. A Model-Building Group (MBG, n = 30) was used to develop the analysis methods, and the methods were subsequently applied to an independent Model-Testing Group (MTG, n = 31).Results: Me were able to correctly, differentiate truthful from deceptive responses, correctly identifying The object stolen, for 93% of the sujects in the MBG and 90% of the subjects in the MTG.Conclusions: This is the first study to use fMRI to detect deception at the individual level. Further work is required to determine bow well this technology will work in different settings and populations.
