Abstract : Respiratory amplitude (RA) and respiratory rate (RR) parameters were examined in student subjects (Ss) following stimulation with five intensities of sound and five intensities of light. All Ss completed the MMPI and were then divided into high and low ego-strength (Es) groups on the basis of their score on the Barron scale and into high and low anxiety groups on the basis of their score on the Taylor scale. These groups were balanced for alertness-drowsiness by EEG criteria. Both RA and RR increased with the greatest changes following greater intensities of stimulation in both modalities. Light induced a greater increase in RA and RR than sound. Habituation occurred in both modalities of stimulation. Peak rates and amplitudes occurred in the same breathing cycle and had the same latency with all degrees of intensity. High Es Ss responded with a greater increase in RA than low Es Ss and habituated more in RR. There were no differences likely to be related to anxiety. (Author)
