Graphs column 1: More Preferred Rewards (MPR) for the Proposer. Graphs column 2: Less Preferred Rewards (LPR) for the Proposer. Empty (E) = Receiver absent; Prosocial (P) = Receiver present; Self (S) = Self-centered scenario, with Receiver absent and Proposer having access to rewards delivered to Receiver compartment. Blue chart bars = significantly different to Empty condition. Graphs framed in green show a significant prosocial response (Prosocial > Empty). Statistically significant differences are in bold and indicated by stars and statistics given on the right. Drawings by Jason Zampol.
