This study aims to examine neural correlates of spontaneous deception in a non-competitive interpersonal situation, and the difference in neural correlates between spontaneous deception and instructed deception using functional near-infrared spectroscopy (fNIRS). We used a modified poker game in which participants freely decided whether sending a piece of truthful/deceptive information to other participants. In the instructed session, participants sent truthful/deceptive information per the instructions. In this non-competitive interpersonal situation in the orbitofrontal cortex (OFC) and dorsolateral prefrontal cortex (DLPFC), deception produced higher neural activities than truth-telling. In addition, spontaneous deception exhibited higher neural activities than instructed deception in the frontopolar area, DLPFC, and frontal eye fields. Spontaneous truth-telling produced higher neural activities than instructed truth-telling in frontal eye fields and frontopolar area. This study provides evidence about neural correlates of spontaneous deception during non-competitive interpersonal scenarios and the difference between spontaneous deception and instructed deception.
本研究旨在使用功能近红外光谱（fNIRS）检查非竞争人际情境中自发性欺骗的神经关联，以及自发性欺骗和指令性欺骗之间的神经关联差异。我们使用了改良版扑克游戏，参与者可以自由决定是否向其他参与者发送真实/虚假信息。在指令性会议中，参与者按照指示发送真实/虚假信息。在这种非竞争的人际情境中，眶额皮层（OFC）和背外侧前额叶皮层（DLPFC）中的欺骗产生的神经活动高于真实告知。此外，在额极区、DLPFC 和额眼区，自发性欺骗的神经活动高于指令性欺骗。在额眼区和额极区，自发性真实告知的神经活动高于指令性真实告知。本研究提供了关于非竞争人际情境中自发性欺骗的神经关联以及自发性欺骗和指令性欺骗之间差异的证据。
