| Description | Ultimatum game is in fMRI tested overwhelmingly from the responder's point of view. We assessed experimental designs which would allow for simultaneous testing of a proposer and a receiver under hyperscanning protocol. Our final laboratory designs use a specific set of choice sets and enables an iterated ultimatum game combined with control condition and dictator game. We run two pilots with different settings. Our results show substantially higher amount of unfair choices in the pilot II compared to pilot I. Empathy as measured by IRI questionnaire can be considered an influential predictor of behavior during experiment. |
