The neural basis of deception in strategic interactions.

Bottom Line: Notably, our design also allows for an investigation of the neural foundations of sophisticated deception through telling the truth-when the sender does not expect the receiver to believe her (true) message.Sophisticated deception triggers activation within the same network as plain lies, i.e., we find activity within the rTPJ, the CUN, and aFG.We take this result to show that brain activation can reveal the sender's veridical intention to deceive others, irrespective of whether in fact the sender utters the factual truth or not.

ABSTRACT
Communication based on informational asymmetries abounds in politics, business, and almost any other form of social interaction. Informational asymmetries may create incentives for the better-informed party to exploit her advantage by misrepresenting information. Using a game-theoretic setting, we investigate the neural basis of deception in human interaction. Unlike in most previous fMRI research on deception, the participants decide themselves whether to lie or not. We find activation within the right temporo-parietal junction (rTPJ), the dorsal anterior cingulate cortex (ACC), the (pre)cuneus (CUN), and the anterior frontal gyrus (aFG) when contrasting lying with truth telling. Notably, our design also allows for an investigation of the neural foundations of sophisticated deception through telling the truth-when the sender does not expect the receiver to believe her (true) message. Sophisticated deception triggers activation within the same network as plain lies, i.e., we find activity within the rTPJ, the CUN, and aFG. We take this result to show that brain activation can reveal the sender's veridical intention to deceive others, irrespective of whether in fact the sender utters the factual truth or not.

Upper Panel: Simple Deception: Results are shown for the contrast simple deception trials vs. truth trials. Lower Panel: Sophisticated Deception: Results are shown for the contrast sophisticated deception trials vs. truth trials. Abbreviations: aFG, anterior frontal gyrus; dACC, dorsal anterior cingulate cortex; rTPJ, right temporo-parietal junction. For visualization, a threshold of 99.4% was applied to the probability maps.

Figure 3: Upper Panel: Simple Deception: Results are shown for the contrast simple deception trials vs. truth trials. Lower Panel: Sophisticated Deception: Results are shown for the contrast sophisticated deception trials vs. truth trials. Abbreviations: aFG, anterior frontal gyrus; dACC, dorsal anterior cingulate cortex; rTPJ, right temporo-parietal junction. For visualization, a threshold of 99.4% was applied to the probability maps.

Mentions: To study the neural correlates of simple deception, i.e., sending a false message with the intention to deceive, we contrast the hemodynamic activation of simple deception trials with truth trials and find activation within the right TPJ, the dorsal ACC, the precuneus extending into the retrosplenial cortex, within the cuneus, the right anterior frontal gyrus (aFG), and a comparatively small activation focus within the anterior medial prefrontal cortex (amPFC) (see Table 4 and Figure 3, upper panel).
