Schematic diagram of the cued choice viewing paradigm. Each trial starts with a fixation cross. Within this cross, a small dot was presented in one of the four quadrants as a cue, and this cue indicated with 100% reliability the position of the emotional picture in the next trial (in this example: the face with a sad expression). Then, a picture pair was presented, consisting of an emotional picture paired with a neutral picture (in this example: Karolinska Directed Emotional Faces image ID AF30NES and AF30SAS). We used a free viewing task, that is, participants were asked to explore the picture pairs freely as if they were watching television. There was no instruction associated with the cue.
