    Abstract: Stimuli related to the self are processed more efficiently in a variety of cognitive tasks. Recent studies have shown that this self-referential bias is modulated by one’s emotional states; however, it remains unclear whether the impact of emotion is primarily attributable to valence or arousal. Experiment 1 measured the self-prioritization effect with a label-shape matching task under four mood states. The results revealed a stronger self-prioritization effect in moods of higher arousal level, and a significant correlation between the arousal ratings and the self-prioritization effect. Experiment 2 further showed that alerting cues, which have been known to elevate the arousal level, boosted the self-prioritization effect measured in a similar label-shape matching task. These results provide clear evidence that arousal modulates self-referential processing
