Boxplots of the average rate of yawning per minute during Baseline (white) and Stimulus (grey) for tongue protrusion Non-imitators (top) and Imitators (bottom).

<p>LPS = lipsmacking condition, TP = tongue protrusion condition, CTRL = control condition. Boxplots depict 1^st and 3^rd quartile, line depicts median, whiskers depict 1.5 times inter-quartile range (IQR). Circles represent mild outliers larger than Q3 + 1.5 * IQR, asterisks represent extreme outliers larger than Q3 + 3 * IQR.</p

Two-Round Trust Game.

<p>Two-round trust game played by subjects after receiving partner’s reputation. In the first round, subjects were assigned to be Player 1 and could choose to move left (labeled “Trust” above) or right (labeled “Distrust” above). If trusted, the partner could reward the subject’s trust by choosing a symmetrically large payoff (labeled “Cooperate” above) or choose a self-favoring payoff (labeled “Defect” above) that yielded less for the subject than if they had initially moved right. If the partner defected, the subject then decided to either punish this decision, paying a small amount to impose a large cost on the partner (labeled “Punish” above), or choose the option with a higher payoff while allowing the partner to profit from his defection. In the second round, the roles were reversed and the partner made the initial decision. Note that decision labels were not displayed to subjects.</p
