Levenson Stanford University University of California, Berkeley Emotion regulation plays a central role in mental health and illness, but little is known about even the most basic forms of emotion regulation. To examine the acute effects of inhibiting negative and positive emotion. we asked 180 female participants to watch sad, neutral. and amusing films under I of 2 conditions. Suppression participants (N = 90) inhibited their expressive behavior while watching the films; no suppression participants (N = 90) simply watched the films. Suppression diminished expressive behavior in all 3 films and decreased amusement self-reports in sad and amusing films. Physiologically. suppression had no effect in the neutral film, but clear effects in both negative and positive emotional films. including increased sympathetic activation of the cardiovascular system. On the basis of these findings, we suggest several ways emotional inhibition may influence psychological functioning. Emotion regulation and dysregulation figure prominently in processes simply overwhelms any attempt at scientific analysis. mental health and illness (Gross & Munoz. 1995). Indeed. by If this view is correct, the reason that little has been done is our count, over half of the nonsubstance related Axis I disorders that little can be done. and all of the Axis II personality disorders involve some form Without minimizing its complexity. we propose that emotion of emotion dysregulation (American Psychiatric Association. regulation can indeed be broken down into pieces that are ame 1994; see also Thoits. 1985).
