Table 1.

Brain regions isolated with the Balanced and Conjunction contrasts of Experiment 1. Except for the bilateral inferior frontal junction (IFJ) and right anterior intra-parietal sulcus (aIPS), none of the ROIs exhibited greater peak response in the Discontinuous than in both the Continuous and Continuous-hard conditions. However, the bilateral IPS, right precuneus, right middle temporal gyrus (MTG), and right inferior frontal gyrus (IFG) showed greater activation for the Discontinuous than for the Continuous condition (all ps<.05, two-tailed), but not than for the Continuous-hard condition (all ps>.1).
