The results of generalized psychophysiological interaction (gPPI) analyses. The presented seed regions were the left dlPFC, left caudate and right IFG (MNI coordinates of peak voxels: Left dlPFC: −36, 54, 14; left caudate: −12, 12, −2; right IFG: 44, 36, 0; radius of sphere: 3 mm; in green). The positive functional connectivity between the left dlPFC and insula, the left caudate and insula, as well as the right IFG and vmPFC during lying significantly correlated with the individual dishonest degree (voxel‐level p < .001 uncorrected, cluster‐level p < .05 FWE correction) [Color figure can be viewed at https://wileyonlinelibrary.com]
