The Effects Of Feedback And Strength Of The Nervous System On Cardiac Rate Control

The influence of two levels of visual feedback (continuous wave-form and no feedback) and three levels of extra-version (high, medium and low) on the ability to decrease heart rate were examined. Forty-eight college students served as subjects with each receiving five alternating three minute rest periods and self-control periods. Heart rate and respiration rate were simultaneously recorded for all trials . . . Paired comparisons revealed that subjects receiving feedback produced greater heart rate decreases on Trial 1 only. Personality differences and autonomic conditionability was discussed. The association between heart rate and respiration rate difference scores was found to be directional, but nonsignificant.
