The simultaneous use of Emotional suppression and Situation selection to regulate emotions incrementally favors physiological responses

Background Emotion regulation alters the trajectories of emotional responses and, when effective, transforms the emotional responses to help individuals adapt to their environment. Previous research has mainly focused on the efficiency of regulation strategies performed individually at a given time. Yet, in daily life, it is likely that several strategies are often combined. Thus, we question in this study the combinatorial efficiency of two emotion regulation strategies, Situation selection and Emotional suppression . Methods In a within-subject design, sixty-five participants were asked to implement either no strategy, Situation selection only, Emotional suppression only, or both strategies together (four conditions) while looking at various emotionally charged images. Experience, expressivity, and physiological arousal were recorded throughout the viewing. Repeated-measures ANOVAs and corrected post-hoc tests were used for analyzing the data. Results The results of the combined strategies showed that Emotional suppression canceled the beneficial impact of Situation selection on negative experience, while significantly increasing the impact on cardiac activity. The use of both strategies together had a greater effect on respiratory function with an enhanced decrease in respiratory rate and amplitude. Conclusions The combinatorial effect of emotion regulation strategies is different according to the emotional response that the individual needs to regulate. The simultaneous use of Situation selection and Emotional suppression could be particularly beneficial to relieve physiological symptoms.
