Decreased intersubject synchrony in dynamic valence ratings of sad movie contents in dysphoric individuals

Abstract Emotional reactions to movies are typically similar between people. However, depressive symptoms decrease synchrony in brain responses. Less is known about the effect of depressive symptoms on intersubject synchrony in conscious stimulus-related processing. In this study, we presented amusi...
