Prosocial and memory tasks

In Experiment 2 participants had to complete three prosocial tasks. The first was an Ultimatum Game, in which each participant was coupled with a partner and had to propose an offer picking from a 100 coins budget assigned in each trial on a total of 10 trials. The illusory partner could accept the offer, leading both to win the amount or not, thus leading both to lose the amount. The second and third prosocial tasks were adapted versions of the Dictator Game, where participants were asked if they would donate an amount (5 options: €10, €20, €30, €40, €50) to an association in the eventuality of winning the final lottery (i.e., a €50 voucher) and whether they would be available to help us and continue with another phase of the study (4 options: 0, 5, 10, 20 min). In Experiment 3, after an interference phase (a Flanker task and a reaction time task), participants had to complete a music memory task testing their recognition (old/new paradigm), recollection (remember/know/guess paradigm) and source memory (i.e., retrieving the social context of the encoding).
