Utility of virtual reality environments to examine physiological reactivity and subjective distress in adults who stutter

- PWS's subjective ratings of distress can be manipulated in virtual reality environments.
- Heart rate and Skin Conductance Level (SCL) did not differ across conditions.
- VREs show promise as clinical tools for PWS.

PurposeVirtual reality environments (VREs) allow for immersion in speaking environments that mimic real-life interactions while maintaining researcher control. VREs have been used successfully to engender arousal in other disorders. The purpose of this study was to investigate the utility of virtual reality environments to examine physiological reactivity and subjective ratings of distress in persons who stutter (PWS).MethodSubjective and objective measures of arousal were collected from 10 PWS during four-minute speeches to a virtual audience and to a virtual empty room.ResultsStuttering frequency and physiological measures (skin conductance level and heart rate) did not differ across speaking conditions, but subjective ratings of distress were significantly higher in the virtual audience condition compared to the virtual empty room.ConclusionVREs have utility in elevating subjective ratings of distress in PWS. VREs have the potential to be useful tools for practicing treatment targets in a safe, controlled, and systematic manner.
