Figure 1.

An example of a trial. Participants were asked to rate the intensity of a particular emotion (in this example, anger) for all 36 emotional faces used in the experiment, each representing 1 of the 6 basic emotions (in this case, fear). The emotion of the rating category and face could be concordant (e.g., rate a happy face on how happy it is) or discordant (such as in the current example). Every face was rated 6 times - once for each emotion category.
