Table 1.
Beta values and standard errors the four linear mixed models predicting punishment behavior in the 2PP, 3PP, and 3PR as well as recompense behavior in the 3PR.

Each model used the size of the dictator's offer, the participant group (LTP vs. control) and their interaction as predictors. The model for punishment in the 2PP (F = 11.5***, observations = 429), punishment in the 3PP (F = 32.3***, observations = 429), punishment in the 3PR (F = 32.1***, observations = 415), and recompense in the 3PR (F = 25.4***, observations = 415) were each significant
