STEM4Youth: Games xBarcelona

STEM4Youth: Games Barcelona.Data collected during the performance STEM4Youth: Games xBarcelona in Barcelona on September 28th, 2017. The participants played different dyadic behavioral games, snowdrift game, dictator's games with punishment and trust game. The participants played these dilemmas in different roles. There were 6 experimental stations, one per individual, spatially distributed so that participants could not see each other. Also, they were rigorously prevented from talking or signaling one another. To further guarantee that potential interactions among players did not influence the results of the experiment, the assignment of players’ partners was completely random. All of the participants played through Citizen Social Lab, a web interface specifically developed for the experiment. The participants were shown a brief tutorial, but were not given any clue. They were informed that they had to make decisions under different conditions and against different opponents. We made sure the interface be the most simple and understandable to ensure the correct understanding of the tasks. Also, the interface was the same for everybody. We made sure to avoid the research be upsetting or harmful for the participants by presenting the experiment as a game and playful activity. One researcher closely monitored each session to guarantee the experimental protocol be strictly followed. Yet, the researchers provided help when required. All participants in the experiment signed an informed consent to participate and no association was ever made between their real names and the results, in agreement with the Spanish Law for Personal Data Protection. This procedure was approved by the Ethics Committee of Universitat de Barcelona, and all methods were performed in accordance with the relevant guidelines and regulations.
