¹Co-player defection vs. baseline: all trials in which the co-player defected (CD + DD);

²Co-player betrayal vs. baseline: trials in which the co-player defected and the player cooperated (CD only);

³Mutual defection vs. baseline: trials in which both players defected (DD);

⁴Co-player cooperation vs. baseline: all trials in which the co-player cooperated (CC + DC).
