Emotion Dynamics in Social Deception Games: Analysis of Players in Werewolf Games

Professional and nonprofessional players exhibit distinct physiological and behavioral patterns during social deception games like Werewolf, revealing how expertise influences emotional regulation and strategic communication.

  • Professional players exhibit significantly more stable skin conductance levels than nonprofessionals, indicating superior physiological regulation during high-stakes social deception games.
  • High physiological arousal in nonprofessional players leads to a tactical shift from persuasion-based communication to reactive information management under pressure.
  • Emotional regulation is a core performance differentiator in social deception environments, allowing professionals to maintain consistent strategic personas regardless of game intensity.

Quantifying Feature Importance of Games and Strategies via Shapley Values

This analysis introduces two novel methodologies for quantifying feature importance in two-player, zero-sum games using Shapley values.

  • Shapley Game Feature Importance (SGFI) quantifies the impact of specific game elements on Nash equilibrium returns, allowing for a global interpretation of which features are most critical for optimal play.
  • Shapley Strategy Feature Importance (SSFI) provides a model-agnostic, local-level explanation of how an AI selects actions in real-time without requiring additional training.
  • Empirical testing in the card game Goofspiel identified 'Center' and 'Deck' cards as the most significant features, confirming that the methodology aligns with human strategic intuition.
