Investigating the Impact of Action Framing Manipulations On Ultimatum Game Players

We previously conducted two experiments investigating the impact of action framing manipulations on ultimatum game players, which consists in priming a player to act in a certain way (preprint available at this address https://psyarxiv.com/xahqp/). In the first experiment, participants played as responders and were asked which offer(s) would either accept or reject (i.e., 1€, 2€, 3€, 4€, 5€, 6€, 7€, 8€ or 9€), while in the second experiment participants played as proposers and were asked which offer(s) would either keep or give. While the result of the first experiment were quite straightforward, with lower minimal acceptable offer in the accept frame than in the reject frame, the results of the second experiment are quite astonishing, with proposers offering more in the keep frame than in the give frame. The aim of present study is twofold: 1) replicating the second experiment in order to confirm or infirm our results (experiment 1); and 2) test the impact of action framing manipulations using another experimental paradigm in which participants would have to choose a single amount (experiment 2 on responders and experiment 3 on proposers).
