Key result
Feedback during an aversive task increased phasic heart rate responses and reduced postimpact heart rate decreases, especially in predictable conditions, whereas control-belief had no effect.

Does feedback and predictability affect heart rate reactivity and task performance during an aversive reaction time task?
Feedback, particularly in predictable conditions, increases phasic heart rate responses during an aversive task, while control-belief has no significant effect.
Baker et al. (2000) conducted an RCT in Active coping in aversive situations (n=96). Feedback, predictability, and control-belief vs. No feedback, no predictability, no control-belief was evaluated on Heart rate reactivity and task performance (reaction time). Feedback during an aversive task increased phasic heart rate responses and reduced postimpact heart rate decreases, especially in predictable conditions, whereas control-belief had no effect.
