The use of feedback training and a stimulus control procedure to obtain large magnitude increases in heart rate outside of the laboratory

Abstract

A series of eight single-subject experiments were performed to test the feasibility of using a stimulus control procedure to teach subjects to control heart rate in the absence of feedback and outside of the laboratory. Four of the six subjects who completed the experiments were able to demonstrate increases in heart rate of from 15 to 35 beats per minute without the assistance of feedback and outside of the laboratory. These increases were consistently produced over six daily sesssions. Through the use of a systematic replication series of experiments, it was possible tentatively to rule out age, sex, and basal heart rate of subject, as well as type of previous feedback training and number of prior training sessions, as accounting for the differential success.
