dc.description.abstractGames are useful tools to simulate social interactions of cooperation or competition and can be applied in conjunction with behavioral and electrophysiological techniques, such as Event Related Potentials (ERP) analysis. The Ultimatum Game (UG) is a well-studied game which can be used to investigate how individuals react to injustice. An initial value is divided between a proponent, who suggests a division rate of this value, and a respondent, who may accept or reject it. If the respondent accepts, both players gain the proposed value, and if he or she rejects, they gain nothing. The behavioral and electrophysiological results have demonstrated typical reactions in the game. The Medial Frontal Negativity (MFN), a component associated with the automatic processing of negative social feedback, and the P300, associated with attention and memory process, are two components commonly observed during UG. While the interaction between volunteers and proponents with typical development is well described, the interaction between volunteers and proponents with Down syndrome is still unknown. This research aimed to investigate differences in the behavioral data, MFN and P300 in participants playing the UG with a typical proposer and Down proposer. 32 subjects participated in the experiment. Scales of social desirability, moral identity, self-esteem and an implicit association test about Down syndrome were applied. The results showed similar behavioral patterns among proponents and previous data described in the literature. Regarding ERPs, the MFN was not detected and there was greater amplitude of P200 component for proposals of the Down. There was also greater amplitude of P300 for fair proposals of the typical proponent compared to the fair proposals of the Down, and of these two compared to unfair proposals of both. The amplitude of the P300 for proposals of typical was negatively correlated with self-esteem scores. Together, the results suggest that the presence of a player with Down syndrome might influence the perception and expectation of the participants about the game, and this effect could be extended to the interaction with the typical proponent. The absence of MFN suggests that participants do not perceived the unfair proposals as a social negative outcome and P300 suggests that the interaction with the typical proposer was more relevant to the participants. Moreover, this relevance was modulated due to personal characteristics of self-esteem. Further studies are suggested in this area to confirm the hypotheses suggested in the present research.eng
