“…The modality of delivery also matters. Emotion inductions that use film clips often result in increases in RSA (Alkon et al, ; Davis et al, ; Hastings, Klimes‐Dougan, Kendziora, Brand, & Zahn‐Waxler, ; Quigley & Stifter, ), which contrasts with patterns observed during naturalistic inductions (like an impossible or frustrating task), which often elicit physiological arousal (Borelli, Burkhart, Rasmussen, Smiley, & Hellemann, ; Hastings et al, ; Perry, Calkins, Nelson, Leerkes, & Marcovitch, ). Using measures of RSA across four emotion contexts, Gaztke‐Kopp and Ram () showed that emotion context‐level physiological change explained a small but unique proportion of the variance in children's RSA scores.…”
