Operant conditioning of heart rate.
Delay of shock was made contingent upon acceleration of heart rate in human subjects. The number of accelerations rose across sessions for these subjects and fell for their yoked-controls who received equal amounts of noncontingent shock. A shorter delay produced more accelerations but faster adaptation. Interpretation of changes in heart rate is confounded by related respiratory changes.
