Task design. After a variable intertrial interval (ITI), subjects were shown an aerial view of the to-be-imagined scene. The start of the 10 s visualization period was prompted by the instruction to “close your eyes”. An auditory tone signaled the end of the visualization period, and subjects were asked to rate the vividness of their imaged scene using the keypad (rating question). After a response (or after 3.5 s if no response was made), subjects were shown an example screenshot of a ground-level view of a portion of a scene for 1 s and then asked whether it was consistent with their imagined scene (while the picture remained on screen; test question). They had 3.5 s to respond using a four-point confidence rating scale (1, sure it was consistent; 2, fairly sure it was consistent; 3, fairly sure it was inconsistent; 4, sure it was consistent).
