Note. In step 1, df = 7, 154; in step 2, df = 16, 145; in step 3, df = 20, 141. RSA = Respiratory sinus arrhythmia, HR = Heart rate, PEP = Pre-ejection period, T = Teacher rating, P = Peer nomination. Resting physiology measures were taken prior to the start of the emotion induction series. Reactivity scores represent raw scores during each emotional clip minus baseline levels averaged across neutral film clips; since RSA reactivity = RSA withdrawal, HR reactivity = increased HR, and PEP reactivity = PEP shortening, increased reactivity is indicated by negative RSA and PEP scores and positive HR scores. No significant interactions emerged between physiological markers (e.g., PEP × RSA).
