Persistence, behavioral choice, and in dorsal anterior cingulate cortex signal. A: persistence is negatively correlated with the effect of effort on choice (n = 18). Regardless of reward, low persistence is associated with a higher preference for options with low effort, whereas high persistence is associated with indifference between options with low effort and options with high effort. B: activity in the dorsal anterior cingulate cortex when the rejected option entailed low effort is positively correlated with persistence (P < .001 uncorrected, 11 voxels; n = 17).
