EEG and Hyperscanning Data from Triadic Prisoner's Dilemma Game

Heegyu Kim's dataset contains simultaneous EEG recordings from three players engaged in an iterated Prisoner's Dilemma game. The data comprises 11 groups of three players, with each group repeating the game 40 times. The dataset was last updated on May 12, 2026.

Use Cases

• Analyze neural correlates of cooperation and betrayal based on EEG signals during the game.
• Study inter-brain synchrony (hyperscanning) patterns among three interacting players.
• Train models to predict strategic choices from neural activity in multi-agent settings.
• Investigate the dynamics of social decision-making across repeated game iterations.

Strengths

• Data is collected from 11 distinct groups of three players, providing multiple social units for analysis.
• Each group completed 40 repeated game trials, offering longitudinal data on strategy evolution.
• Simultaneous EEG recording from three players enables true hyperscanning analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
