“…As a consequence, the FMMS excerpts selected in the present study were previously edited by shortening them to 8 s in order to ensure a similar trial duration within the task, being therefore comparable to prior music studies (Gringas et al, 2015;Khalfa et al, 2002), as well as other works using emotional pictures or sounds in diverse paradigms such as passive viewing, aversive conditioning, or cognitive reappraisal tasks (Conzelmann et al, 2015;Fuentes-Sánchez et al, 2019;López et al, 2009). Thus, the first objective was to investigate the correspondence between the subjective ratings obtained in the a priori validation study-with longer and variable excerpts durations (Fuentes-Sánchez et al, 2020)-and those obtained here for the shortened excerpts. A second goal was to investigate the effect of music category (unpleasant, neutral, and pleasant music) on (a) peripheral physiology (EDA, HR changes, zygomatic, and corrugator)-analyzing both specific parameters such as peak response or averaged activity and the time course across half-seconds bin; and (b) subjective ratings-both for affective dimensions (valence, energy, and tension arousal) as well as discrete emotions (happiness, anger, fear, tenderness, and sadness).…”
