Overview of the Session 1 procedure in Study 1. Dashed outlines indicate the times when saliva samples were collected. Baseline saliva sample was obtained right after consenting and post-interaction and recovery saliva samples were obtained 18 min and 33 min following the onset of the in-person interaction, respectively. Cortisol recovery was calculated by subtracting the final cortisol level from the second cortisol level (post-interaction minus recovery). Testosterone reactivity was computed by subtracting the first testosterone level from the third testosterone level (recovery minus baseline). Gray boxes indicate the times when electrocardiographic (ECG) signals were obtained. RSA reactivity was calculated based on the ECG data by subtracting RSA scores during the last minute of participants’ baseline data from the corresponding scores obtained during the first minute of the in-person interaction. A lower number on this reactivity index indicates greater vagal withdrawal.
