172 Chapter 6 SUPPLEMENT S6.2 The present study includes a shortened version of the EA task with an approximate duration of 25 minutes instead of the 50 minutes of the original version of the task. The subset of videos was derived from a pilot study in a student sample (n = 20) in which we tested the feasibility of the already existing EA task in combination with an eye tracking set-up. Videos were selected based on their feasibility for eye tracking purposes (i.e., videos in which targets were excessively moving were excluded) and sufficient variety in EA ratings per video in the pilot study (range mean EA between 0.35-0.85; SD > 0.30). Also, we tested two versions of the task in which one version contained the presentation of the 9-point Likert scale of the dial below the video on the screen (similar to the original task), while the other version did not include the presentation of this scale on the screen. The data of the pilot indicated that participants often looked at the scale on the screen instead of the video, which was not desirable for the eye tracking measures. We therefore decided to use the version without the scale on the screen for the present study.
