Abstract

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.
