Effects of instructed emotion regulation on valence, arousal, and attentional measures of affective processing

Abstract

Cognitive control of emotion has been investigated using tasks prompting participants to increase or decrease emotional responding to affective pictures. This study provides a more comprehensive evaluation of responding in this task by including: pleasant and unpleasant pictures, increase and decrease instructions, additional physiological measures, and a fully randomized design. Findings suggest that control efforts did modulate higher-level affective responses indexed by self-reported valence and expressive facial muscles, but not lower-level affective responses indexed by startle blink and heart rate. Similarly, electrocortical measures evidenced expectable affective responses and control-related activity, but no modulation of affective patterns due to the control efforts.
