Because the effectiveness of the emotion regulation strategy cognitive reappraisal may vary with emotion intensity, we investigated how stimulus arousal affects reappraisal success. Participants up- and down-regulated emotional responses using cognitive reappraisal to low and high arousing unpleasant pictures while the electroencephalogram (EEG) was recorded. Up-regulation resulted in more negative self-reported valence, while down-regulation resulted in less negative self-reported valence regardless of stimulus arousal, suggesting that subjective reappraisal success does not vary with emotional intensity. Participants felt that down-regulation of emotional responses to low arousing unpleasant pictures was easiest, which is in line with previous findings that participants showed a greater preference for reappraisal in low than high arousing situations. The late positive potential (LPP) amplitude was enhanced by down-regulation of high arousing unpleasant pictures. Even though this effect was unexpected and is opposite to the typical effect of down-regulation on the LPP, it is in line with several previous studies. Potential explanations for LPP regulation effects in the unexpected direction, such as strategy selection and task design, are evaluated. Suggestions and recommendations for future research are discussed, including using trial-by-trial manipulation of regulation instructions and studying the effect of stimulus arousal on up- and down-regulation of positive emotions.
