Methodological details. (a) Example semantic item. This item is a match, and is shown surrounded by a box that appears when the “match” button is pressed (the box confirms the button press, but no information on accuracy is provided). (b) Example perceptual item. This item is a mismatch, so the button should not be pressed. (c) An illustration of how the Dice coefficient of similarity captures the extent of overlap between two thresholded images. (d) Regions of interest in a representative participant and projected onto the lateral surfaces of a template brain. ROI 1 (Brain) encompassed the whole brain. ROI 2 (Supra) encompassed regions shown in red, green or blue. ROI 3 (Lang+) corresponded to regions shown in red or green. ROI 4 (Lang) is shown in red
