  • A 2 emotion (positive, neutral) × 2 set (Set1, Set2) two-way ANOVA was performed on the valence and arousal ratings of the scene stimuli. A main effect of emotion was observed in both the valence and arousal ratings with the positive scenes being rated higher in both valence and arousal than the neutral scenes. No emotion × set interaction was observed for both valence and arousal ratings.
