Description: For each participant, the design matrix included regressors for the blocks of picture presentations, separate for all four combinations of conditions (Neutral Real, Neutral Game, Violent Real, Violent Game). As nuisance regressors, we included regressors for the rating events. We then subjected the beta images of the first-level contrasts of interest to a two-sample t-test, and identified the voxels in which the contrast Control Group > Experimental Group was significant and positive. For the interaction Group*Content (testing whether participants in the violent game group had decreased responses to violent images in general), the contrast of interest was [Violent Real + Violent Game]/2 - [Neutral Real + Neutral Game]/2.
