(a) Experimental design. Each of the four sessions consisted of four fMRI runs. In each run, all three tasks were presented in a pseudo-randomized order and analyzed in an event-related fashion. (b) Attentional reorienting task. In each trial, a directional arrow appeared at the center of the screen to direct the subject’s attention to the left or right. In 75% of the trials, the arrow correctly predicted the position of the target (valid condition), in 20% of the trials, the target appeared on the opposite side and subjects had to reorient their attention (invalid condition). In 5% of the trials, no response was prompted (catch condition). Subjects indicated the side of the target via button press. (c) Lexical decision task. Participants performed lexical decisions (word or pseudoword condition) based on concrete German nouns or well-matched pseudowords. (d) Perspective taking task. In each trial, character A places a target object in a container. Thereafter, character B changes the location of the target object. Character A has left the room (false belief condition) or watches the relocation of the object (true belief condition). Character A then searches for the target object at the location congruent with her / his knowledge (expected) or at the contradicting location (unexpected). Participants had to indicate via button press whether character A searched at the expected location or not. Behavioral results for each task are shown in the right panel, separately for each session. Single subject data is overlaid as circles.
