abstract="After a 10 min. recording of normal respiration and pulse, records were taken during a 10 min. period of stimulation by a 60-cycle tone from an oscillator, so controlled automatically by a rheostat that the sound gradually came to full intensity and subsided, at rates of from 10 to 25 per min. Results secured from two experimental groups, one instructed to relax, the other without instructions, and from a control group are reported. Respiration rate approximated the rate of the sounder, but pulse rate made little consistent change in any direction. Relaxation occurred whether the sounder rate was faster or slower than the normal respiration rate. (PsycINFO Database Record (c) 2012 APA, all rights reserved)<p />",
