Dual-process theories distinguish between intuition (fast and emotional)
and reasoning (slow and controlled) as a basis for human decision-making. We
contrast dominance-solvable games, which can be solved by step-by-step
deliberative reasoning, with pure coordination games, which must be solved
intuitively. Using functional magnetic resonance imaging, we found that the
middle frontal gyrus, the inferior parietal lobule,
and the precuneus were more active in
dominance-solvable games than in coordination games. The insula
and anterior cingulate cortex showed the opposite
pattern. Moreover, precuneus activity correlates
positively with how ¡§effortful¡¨ a dominance-solvable game is, whereas insula activity correlates positively with how
¡§effortless¡¨ a coordination game is. |
