A stress mindset manipulation can affect speakers’ articulation rate

ABSTRACTABSTRACTBackground and Objective Mindsets about stress can be altered so that people interpret stress as either a positive or negative force. We exposed participants to a stress mindset intervention to test its effects on a challenging speech production task.Design and Method Participants (N = 60) were randomly assigned to a stress mindset condition. In the stress-is-enhancing (SIE) condition, they viewed a brief video that characterized stress as a positive force that benefits performance. In the stress-is-debilitating (SID) condition, the video characterized stress as a negative force that should be avoided. Each participant completed a self-report measure of stress mindset, performed a psychological stressor task, and then repeatedly produced tongue twisters aloud. Speech errors and articulation time were scored for the production task.Results The manipulation check confirmed that stress mindsets were altered after viewing the videos. Participants in the SIE condition articulated the phrases more quickly than those in the SID condition without an accompanying increase in errors.Conclusions A stress mindset manipulation affected speech production. This finding indicates that one way to mitigate the negative effects of stress on speech production is to instantiate beliefs that stress is a positive force that can enhance performance.KEYWORDS: Mindset interventionstress mindsetspeech productiontongue twisters AcknowledgementsThis research fulfilled Jessica Baynard-Montague’s thesis requirement for the MA degree in Psychological Science from the University of Colorado Colorado Springs.
