Comforting Apprehensive Communicators: The Effects of Reappraisal and Distraction on Cortisol Levels Among Students in a Public Speaking Class

The aim of this study was to examine the effects of interpersonal communication as a source of comforting on the physiological stress associated with giving an in-class speech. Cortisol was used as an objective measure of stress reactivity, and the effects of distracting or reappraisal messages were examined. Salivary cortisol was collected from 42 students enrolled in an introductory public speaking course, in five intervals. The final collection showed that participants in the distraction condition experienced significantly less stress than participants in the control condition. The discussion highlights the importance of understanding the trajectory of decay to detect the stress-reducing benefits of comforting communication.
