Testing emotional response coherence assumptions: Comparing emotional versus non-emotional states.

Abstract

Although central to theories of emotion, emotional response coherence, that is, coordination among various emotion response systems, has received inconsistent empirical support. This study tests a basic assumption of response coherence, that is, that it characterizes emotional states defining their beginning and end. To do so, we (a) compare response coherence between emotional versus non-emotional states and (b) examine how emotional coherence changes over time, before, during, and after an emotional episode. Seventy-nine participants viewed neutral, pleasant, and unpleasant film clips and rated continuously how pleasant they felt (experience) before (anticipation), during, and after (recovery) each clip. Autonomic physiological arousal responses (skin conductance level, heart rate; physiology) and facial expressions (corrugator, zygomatic activity; expression) were recorded. Within-person cross-correlations between all emotional response pairs were calculated for each phase. Analyses comparing coherence during emotional versus neutral film viewing showed that only experience-expression coherence was higher for emotional versus neutral films, indicating specificity for emotional states. Examining coherence across phases indicated that coherence increased from anticipation to emotional film viewing, as expected, for experience-expression and experience-physiology pairs (SCL only). Of those pairs, increased coherence returned to baseline during recovery, as theoretically assumed, only for experience-corrugator activity coherence. Current findings provide empirical support for theoretical views of response coherence as a defining feature of emotional episodes, but mostly for the coherence between experience and facial expressions. Further research needs to investigate the role of sympathetic arousal indices, as well as the role of response coherence in emotional recovery.
