@article { petisca16, abstract = {Is a robot that shares explicitly its emotions with users more believable and friendly? In a previous study addressing this question, results suggested that an emotion sharing feature in a robot may have negative effects in the perception of that robot. Here, we address the same question but also take into account the ``competence'' of a robot executing a task, to understand if some kind of interaction occurs. To understand if emotional sharing could bring changes to the participants perceptions towards an autonomous robot that played a game against them, we performed two studies. In the first study, the robot had a high competence in the game and in the second a low competence. In each of these studies two conditions were formed: Sharing Condition (the robot would do small talk and comment on its feelings regarding the result of the board) and No Sharing (the robot would only do small talk). Participants were randomly assigned to one of the conditions following a between-subject design methodology. We expected that in the Sharing Condition, participants would feel greater involvement with the robot changing their perceptions towards it in contrast with the less caring and emotionally limited condition. The results of the studies did not follow what we expected, neither an interaction was found with the competence level. Still some interesting results were seen.}, journal = {RO-MAN Conference}, keywords = {Social Robotic Companions;}, title = {Emotional Sharing Behavior for a Social Robot in a Competitive Setting}, year = {2016}, author = {Sofia Petisca and João Dias and Patrícia Alves-Oliveira and Ana Paiva} }
