Figure 1

Following a fixation cross, participants received a 5 second heat stimulus (painful and non-painful heat, pain block) or viewed for 5 seconds a picture (of neutral, pain-disgust or “pure” disgust content, disgust block). Participants rated pain, disgust as well as valence and arousal after each stimulus.
