Recent neuroimaging studies have found a broad network of brain regions involved in deception, including the prefrontal cortex, insula, anterior cingulate cortex (ACC), and inferior parietal lobule (IPL). Although deception can be conceptualized as the attempt to deliberately cause another person to accept a false belief, research to date has mainly focused on executive control processes when participants are instructed to lie under certain conditions. Recently, more ecologically valid and interactive experimental paradigms have been used in which subjects were also requested to take the perspective of another person, read his or her intentions, and make a self-determined decision to deceive that person and break a moral rule. To investigate the influence of these socio-cognitive processes on the neural network of deception, we performed a quantitative meta-analysis combining the data from 416 participants across 22 fMRI and two PET studies. Based on the description of the experimental paradigm, studies were divided in social interactive and non-interactive deception studies. Increased activation in the dorsal ACC, the right temporo-parietal junction (TPJ)/angular gyrus, and the bilateral temporal pole (TP) was found to be greater in social interactive than in non-interactive deception. These results demonstrate the important role of perspective taking, theory of mind, and moral reasoning processes in deception as well as conflict processing. In addition to the role of executive control processes determined by previous meta-analyses, our findings show the importance of these socio-cognitive processes in deception and give new insight into the function and interpretation of the brain regions involved.
最近的神经影像学研究发现，有一个广泛的脑区网络参与欺骗行为，包括前额叶皮层、脑岛、前扣带回皮层（ACC）和顶下小叶（IPL）。虽然欺骗可以被概念化为故意使他人接受错误信念的企图，但迄今为止的研究主要集中在参与者在特定条件下被指示说谎时的执行控制过程。最近，人们采用了更符合生态效度且具有交互性的实验范式，在这些范式中，受试者还被要求从他人的角度出发，解读其意图，并自主决定欺骗那个人并违反道德规则。为了研究这些社会认知过程对欺骗神经网络的影响，我们进行了一项定量荟萃分析，综合了来自22项功能磁共振成像（fMRI）研究和两项正电子发射断层扫描（PET）研究的416名参与者的数据。根据实验范式的描述，研究被分为社会交互性欺骗研究和非交互性欺骗研究。结果发现，与非交互性欺骗相比，社会交互性欺骗中背侧ACC、右侧颞顶联合区（TPJ）/角回以及双侧颞极（TP）的激活增加更为明显。这些结果证明了在欺骗以及冲突处理过程中，采择视角、心理理论和道德推理过程的重要作用。除了先前荟萃分析所确定的执行控制过程的作用外，我们的研究结果还表明了这些社会认知过程在欺骗中的重要性，并为所涉及脑区的功能和解释提供了新的见解。
