Ichikawa et al. (Wed,) conducted a rct in Physiological and emotional stress response (n=15). Negative non-verbal feedback vs. Video recording without face-to-face feedback was evaluated on Decrease in RRI (msec) during task compared to rest. Negative non-verbal feedback during a presentation task elicited the largest decrease in RRI (181.4 msec) compared to positive feedback (129.3 msec) and no face-to-face feedback (48.4 msec).
