Effect of Suppression, Reappraisal, and Acceptance of Emotional Pictures on Acoustic Eye-Blink Startle Magnitude.

To examine the effects of different emotion regulation strategies on acoustic eye-blink startle, 65 participants viewed positive, neutral, and negative pictures and were instructed to suppress, reappraise, or accept their emotional responses to these pictures using a within-group experimental design with separate blocks of pictures for each strategy. Instructions to suppress the emotional response led to an attenuation of the eye-blink startle magnitude, in comparison with instructions to reappraise or accept. Reappraisal and acceptance instructions did not differ from one another in their effect on startle. These results are discussed within the context of the existing empirical literature on emotion regulation.
