我们进行了一项功能性磁共振成像（fMRI）研究，以阐明有害和有益的不诚实决定的神经认知机制。在扫描过程中，受试者阅读有关现实生活中可能发生的事件的场景，并被要求决定是否像他们正在经历这些事件一样撒谎。一半的场景由有害的故事组成，其中不诚实的决定可以被视为不好的谎言，另一半则由有益的故事组成，其中不诚实的决定可以被视为好的谎言。与控制决策任务相比，我们发现，涉及诚实或不诚实的决策任务招募了一个包括左背外侧前额叶皮层在内的大脑区域网络。在有害故事中，与诚实的决定相比，当受试者做出不诚实的决定时，右颞顶联合区和右内侧额叶皮层被激活。没有哪个地区会对有用的故事中做出的诚实和不诚实的决定进行区分。这些初步发现表明，不诚实决定的神经基础是由说谎是否有助于伤害或帮助目标来调节的。(C)2014爱思唯尔公司All rights reserved.
We conducted a functional magnetic resonance imaging (fMRI) study to elucidate the neurocognitive mechanisms of harmful and helpful dishonest decisions. During scanning, the subjects read scenarios concerning events that could occur in real-life situations and were asked to decide whether to tell a lie as though they were experiencing those events. Half of the scenarios consisted of harmful stories in which the dishonest decisions could be regarded as bad lies, and the other half consisted of helpful stories in which the dishonest decisions could be regarded as good lies. In contrast to the control decision-making task, we found that the decision-making tasks that involved honesty or dishonesty recruited a network of brain regions that included the left dorsolateral prefrontal cortex. In the harmful stories, the right temporoparietal junction and the right medial frontal cortex were activated when the subjects made dishonest decisions compared with honest decisions. No region discriminated between the honest and dishonest decisions made in the helpful stories. These preliminary findings suggest that the neural basis of dishonest decisions is modulated by whether the lying serves to harm or help the target. (C) 2014 Elsevier Inc. All rights reserved.
