摘要
基于功能性近红外光谱技术,采用半自发说谎范式考察对个人信息自发说谎的神经机制.实验以26名大学生志愿者为研究对象,将其分为说谎组和控制组.在说谎组中,要求研究对象对个人信息进行自发说谎;而在控制组中,要求研究对象对个人信息全部说真话.研究采用含氧血红蛋白增量作为神经激活的指标.结果表明,对个人信息进行自发说谎可引发左侧额中回的显著激活,不进行自发说谎的则不引发前额皮层区域的显著激活.
The characteristics,classification and experimental paradigm of spontaneous deceptions are studied. By introducing optical brain imaging technique,the advantages of using functional near-infrared spectroscopy（ f NIRS）to examine neural mechanism of spontaneous deceptions are summarized,and the relevant studies are reviewed.The recent study shows that,spontaneous lie to personal information is associated with activation of the left middle frontal gyrus. This result once again proves significance of the prefrontal cortex during spontaneous deceptions and the feasibility of utilizing f NIRS to detect the cortical response to deception.
