我们研究了三名进行隐藏信息测试(CIT)的受试者欺骗的功能磁共振成像(FMRI)模式的认知基础。在所有参与者中，前额顶叶谎言的激活模式类似于我们之前报道的fMRI CIT研究的荟萃分析(N=40)，当以被动观看目标项目取代谎言反应时，该模式没有变化。当谎言被无关紧要的反应取代时，所有受试者都只有左侧下回被激活。这项研究提出了一种检验欺骗模型认知基础的系统策略，并对单一受试者的真实性验证功能磁共振成像测试进行了定性研究。
We studied the cognitive basis of the functional magnetic resonance imaging (fMRI) pattern of deception in three participants performing the Concealed Information Test (CIT). In all participants, the prefrontoparietal lie activation was similar to the pattern derived from the meta-analysis (N=40) of our previously reported fMRI CIT studies and was unchanged when the lie response was replaced with passive viewing of the target items. When lies were replaced with irrelevant responses, only the left inferior gyrus activation was common to all subjects. This study presents a systematic strategy for testing the cognitive basis of deception models, and a qualitative approach to single-subject truth-verification fMRI tests.
