Fairness or Efficiency? The Impact of Completion Motivation on Prosocial Behavior Preferences

Encode the help context, where 0=Unfinishable help context and 1=Accomplishable help context; Encode the effectiveness of the help, where 0 represents a scenario with an efficiency bias of 20% and 1 represents a scenario with an efficiency bias of 80%; Encode help preferences, where 0=fairness bias and 1=efficiency bias.

In addition, the relative sense of completion in Study 3 is the difference between completion motivation and fairness motivation. The differences in donation amount, completion motivation, and sense of responsibility in Study 5a are all differences (with progress reminder - without progress reminder).
