Raynor, D. A., & Raynor, J. O. (1996). Effects of auditory stimuli on perceived exertion and behavior during aerobic exercise. Medicine and Science in Exercise and Sports, 28(5), Supplement abstract 427.

The influence of auditory stimuli (e.g., music, auditory book, negative sound effects) and a white noise control on ratings of perceived exertion (RPE) during an acute bout of aerobic exercise was evaluated.

No significant differences in heart rate were found between conditions. RPE in the music condition was significantly lower than the control (white noise) condition. The psychological component of the music condition affected the RPE as well as the physiological demands of the task.

Implication. Psychological variables can cause RPE to change even though the task remains constant.
