Figure 3. The procedure of the experiment. Note: Movie clips are played in a random order.  The whole procedure is demonstrated in Figure 3. The participant was invited to sit on a couch in the test room at the laboratory. The participant was then asked to read and sign an informed consent form. After signing the agreement, the participant put on electrodes and physiological sensors fol- owing the experimenter’s instructions. The con- nection of the sensors was checked while the participant was filling in a short questionnaire on demographic data. Once the questionnaire was filled in, the experimenter gave a tutorial about the experiment and an example of what the partici- pant should do throughout the session.   Twenty-two volunteers participated in our study. Most of the participants were undergraduate or graduate students at the Technical University of Catalonia. We also recruited several participants
