Group differences in cortical thickness (correct vs. incorrect responses in the partial-knowledge condition). Accounting for sex, age, working memory, cognitive control, and reasoning, the group that responded correctly showed greater cortical thickness in a region within the left mid- and superior orbitofrontal cortex (A.), and thinner cortex in bilateral superior parietal cortex (B.), as compared to the group with at least one incorrect response.
