The present study consists of two experiments, the first of which is an extension of a preceding study. To test a hypothesis that the possibility of interoceptively detecting cardiac activity is enhanced by increasing the strength of concentration, an attempt was made in Experiment I to train subjects for sustained concentration by combining biofeedback technique with a cardiac-motor coupling procedure. The results demonstrated that a significant improvement in interoceptive cardiac detection developed along with such training. Experiment II was designed to determine whether the interoceptive detection facilitates subsequent learned cardiac control. The Experimental group showed better cardiac control than the Control group. These findings were taken to suggest some substantial relationship between the detection and the control. However, the effect of detecting interoceptive signals upon the cardiac controllability was not so much powerful as expected. In this respect, the role of intrinsic effector-produced feedback as a possible factor was proposed and discussed.
