Fig. 1.

Stimuli and experimental set up. The left-side depicts scenes from one introductory video. Before each scanning block two different introductory videos were shown (30 s per video). The centre depicts scenes from a typical movie sequence viewed by participants during fMRI scanning. Each sequence began with a new movie followed by eight experimental clips. For each movie clip the toy animal could hide and the actor could search in the same (repeated) or different (novel) location with respect to the previous movie. As such, each clip fell evenly into a 2 × 2 factorial design for hide and search, novel and repeated (abbreviations are: n = novel, r = repeated, H = hide, S = search). Following a sequence, participants answered a yes-no question regarding the previous movie, then rested. The right side shows six scenes from one trial. On each a trial, a toy animal (e.g. a frog) would hide in one of two locations (e.g. between bed sheets or books) and an actor would open the curtains and search in one of the two locations.
