  1. We calculate mean values and standard deviations of p and q for all 70 rounds, and separately for rounds 1 to 35 and rounds 36 to 70. Mean(p) and SD(p) represent the mean value and the standard deviation of offers of all proposers, respectively, in which a proposer’s offer p is taken as the average of his/her offers p over 1-70 rounds/1-35 rounds/36-70 rounds. Similarly, Mean(q) and SD(q) represent the mean value and the standard deviation of acceptance levels q of all responders, respectively, in which a responder’s acceptance level is taken as the average of his/her acceptance levels q over 1-70 rounds/1-35 rounds/36-70 rounds.
