Does Baseline Stress Affect Electrodermal Activity? A Serious-Game-Based Pilot Study.

Area of Science:

• Psychophysiology
• Biomedical Engineering
• Stress Research

Background:

• Electrodermal activity (EDA) is a key physiological stress indicator.
• Short-term stress responses via EDA are well-researched.
• The influence of long-term baseline stress on EDA is largely unexplored.

Purpose of the Study:

• To investigate the relationship between baseline stress and EDA.
• To explore EDA as a marker for chronic stress levels.
• To assess if EDA can differentiate between stress groups.

Main Methods:

• Utilized a serious game for controlled stress induction.
• Simultaneously recorded electrodermal activity (EDA) during gameplay.
• Employed statistical analysis and shallow learning models for data interpretation.

Main Results:

• EDA features showed moderate correlation with perceived stress over the past month.
• Significant differences in EDA were observed between low and moderate baseline stress groups.
• Machine learning models achieved over 90% accuracy in classifying stress groups using EDA data.

Conclusions:

• Baseline stress demonstrably affects electrodermal activity (EDA) responses.
• EDA shows promise as a quantifiable marker for assessing long-term stress.
• Findings support the hypothesis that chronic stress influences physiological stress markers.
