Loalization of regions of significant activity during the incompatible mapping condition relative to the compatible mapping condition across all subjects is presented in the top half. The graphs from left toright show (1) percent change in MR signal intensity in the inferior frontal cortex/insula cortex as a function of percent change in accuracy for incompatible relative to compatible trials, (2) percent change in MR signal intensity in the caudate nucleus as a function of accuracy, (3) percent change in MR signal intensity in the thalamus for incompatible trials as a function of the child's age, (4) percent change in MR signal intensity in the hippocampus as a function of percent change in reaction time for incompatible relative to compatible trials. Closed circles are data from children, and open circles are data from adults.
