Why the study?
Does augmented sensory feedback improve voluntary control of heart rate?
Does augmented sensory feedback improve voluntary control of heart rate?
Augmented sensory feedback directly improves the voluntary control of heart rate in a dose-dependent manner based on exposure frequency.

May enhance efficiency of heart rate biofeedback with intermittent feedback; leaves open applicability to clinical populations.
The aim of this experiment was to determine the effect of different exposures to augmented sensory feedback of heart rate performance on the development of voluntary control of heart rate. Three groups of five S s each received augmented sensory feedback on 100%, 50%, or 0% of training trials respectively. The amount of heart rate control exhibited by S s was observed to be a direct function of the percentage of training trials on which feedback was given. Respiration rate changes were not systematically influenced by this variable although higher respiration rates were consistently associated with high heart rates and lower respiration rates with low heart rates.
