Chapter 6136individuals, Kawan, managed to pass all phases of the training (between July and December 2019). Thus, this resulted in a total sample of three participants.Figure 1 – Schematic depiction of a dot-probe task trial with large and small flanges as competing stimuli. The arrow indicates the temporal progression of the trial.Preference taskThe procedure of the preference task was adapted from Watson et al. (2012). Each session consisted of two parts (Figure 2): a forced-trial procedure (8 trials) and a choice-trial procedure (16 trials). During all parts of the experiment, the background was silver gray (#c0c0c0). Trials in the forced-trial procedure started with a 300x300-pixel black dot that appeared in a random position. This randomly located dot was added at the start of each trial to avoid anticipatory responses. After clicking the dot, a similar dot appeared exactly in the center of the screen. By clicking this dot, individuals would advance to a screen that depicted either a red dot or a green dot. The shades of green (#339900) and red (#990000) were almost equal in saturation. Each dot colour was associated with one specific stimulus Tom Roth.indd 136 08-01-2024 10:41
