Psychophysiological correlates of science communicators

Area of Science:

• Psychophysiology
• Communication Science
• Public Speaking

Background:

• Expert science communicators possess high self-esteem and prosociality.
• These traits positively correlate with communication effectiveness and inversely with age.

Purpose of the Study:

• To evaluate heart rate variability (HRV) in expert science communicators during a live interview.
• To explore the psychophysiological basis of expertise in stress regulation during public speaking.

Main Methods:

• 32 expert science communicators underwent HRV monitoring during pre-interview, interview, and post-interview phases.
• Communication skills were assessed by an external jury on indices including Authoritativeness and Clarity.
• Participants completed surveys on socio-demographics and psychological profiles.

Main Results:

• HRV total power and low-frequency components were higher post-interview than during or pre-interview.
• Subgroups with low Authoritativeness and Clarity showed significant stress response and recovery patterns in HRV.
• Subgroups with high Authoritativeness and Clarity exhibited less HRV variation, indicating better stress management.

Conclusions:

• Expertise in science communication, particularly high Authoritativeness and Clarity, is associated with enhanced stress regulation during public speaking.
• Physiological responses, measured by HRV, provide insights into the psychophysiology of communication expertise.
• Findings suggest that communication skills training may influence stress management in public speaking contexts.
