Psychophysiological Effects of Music

"Participants went through four stages. In the rest stage, they were instructed to relax. In the neutral control stage, they watched an informative video about plastic injection molding. In the sadness induction stage, they viewed sad clips from either Hachi: A Dog's Tale or My Brother and Sister, with the order randomized across participants. In the music intervention stage, they listened to the cheerful Cuckoo Waltz. Each stage lasted for about 6 minutes.~The interventions for the two groups were exactly same.~PS: On the basis of the PHQ-9, this HAMD interview was conducted to further group the participants. So, following the experimental protocol, participants who scored ≥ 5 on the PHQ-9 measure underwent the HAMD interview, while the remaining individuals were simply interviewed about their feelings during the experiment."
