Abstract
One foundational distinction in affective science is between emotion reactivity and emotion regulation. This conceptual distinction has long been assumed to be instantiated in spatially separable brain systems (e.g., amygdala/insula for reactivity and frontoparietal areas for regulation). In five studies involving healthy and clinical samples (total n=336), we assessed neural responses using fMRI while participants were asked to either react naturally or regulate their emotions (using reappraisal) while viewing emotionally evocative stimuli. Across five studies, we failed to find support for the neural separability hypothesis. In univariate analyses, both presumptive “reactivity” and “regulation” brain regions demonstrated equal or greater activation during the reactivity condition than during the regulation condition. In multivoxel pattern analyses (MVPA), classifiers decoded reactivity trials more accurately than regulation trials using multivoxel data in both presumptive “reactivity” and “regulation” regions. These findings suggest that emotion reactivity and regulation – as measured via fMRI – may not be as separable in the brain as previously assumed.
