Beschreibung

Adaptive emotion regulation (ER) is conducive to physical and mental health, whereas dysfunctional ER is central to psychopathology. Emotion can be regulated with 'experiential ER', which refers to the affectively attending, acknowledging and getting awareness of the bodily felt feeling in an accepting and welcoming way. Also, emotion can be regulated with 'cognitive reappraisal' by which reinterpretations of a situation can change one’s emotions about it. To address the effectiveness of these two ER strategies, a series of experiments has been conducted in our lab. Study 1 compared both experiential ER and reappraisal relative to a neutral ER baseline and its impact on sleep physiology in 43 healthy participants. Stress was triggered with an emotional failure induction, after which ER was induced twice. The use of reappraisal resulted in more fragmented and restless sleep when compared to experiential ER or neutral baseline. Study 2 further compared experiential ER and reappraisal based on their repeated usage in 69 healthy female participants using physiological measurements. Compared to watch negative condition, the skin conductance response was decreased by experiential ER in the third time (p=0.017) while the zygomatic activity (p=0.012) and respiration amplitude (p=0.016) were increased by reappraisal in the third time. Our results suggested experiential ER works effectively in decreasing the arousing level of emotions while cognitive reappraisal works effectively in producing positive feelings. Study 3 further compared the repeated effects of experiential ER to cognitive reappraisal in the brain in 35 female participants while their respiration and heart rate were recorded simultaneously during the fMRI scanning. The aim of the data analysis is to disentangle the body-brain relationship representing these two ways of regulating emotions by using the physiological data as parametric modulator vector corresponding to the onset time of each experimental conditions. In this way, we hope to identify the covariant regions in the fMRI signal with the single-trial physiological measure. A challenge is to extract the single-trial physiological measures, which we would like to have your suggestions. In addition, it would be interesting to discuss other options of analyzing the fMRI data to have higher sensitivity to detect the neural mechanisms involved in these two ways of regulating emotions.
