Illustration of the experimental procedure. Pictures of 4 face actors (A, B, C, D) displaying happy, neutral, and angry facial expressions were presented randomly (1 s each) in 2 experimental tasks (each 720 trials). Participants were instructed to attend all stimuli in the passive viewing task. Following picture ratings, the main instruction about social contingencies was given: “You are going to meet one of these two people at the end of the experiment” (here indicated by an arrow). Finally, participants again rated face stimuli and were debriefed.
