The study explored using HeartMath heart rate variability biofeedback training to increase empathy and ethical decision-making in business students. Students in an experimental group received HeartMath training while a control group did not. Both groups were taught the Ross-Garrett model of ethical decision-making and took pre- and post-tests of empathy and ethical judgments. Scores increased for both groups from pre- to post-test in the predicted directions, with slightly greater increases in the experimental group, suggesting the HeartMath training may have had a positive impact though the small sample size limited statistical power.
