• The purpose of this study was to investigate effects of widely used laboratory stressors upon respiratory activities and to find parameters which showed a consistent change to various stressors. Twenty healthy undergraduate males participated in all three sessions in the following fixed order : mental arithmetic, the stress film, and the cold pressor test. Each session consisted of one stressful task and one or two non-stressful tasks. Respiratory parameter showing a consistent change to different stressors were minute ventilation volume and post expiration pause time. Minute ventilation significantly increased and pause time significantly decreased to a stressful task and a non-stressful stimulus. These two respiratory parameters can be used to mark a relaxation response since they responded sensitively to mild psychological stimuli.
