{"pk":21518,"title":"People balance joint reward, fairness and complexity to develop social norms in a two-player game","subtitle":null,"abstract":"Social norms are a hallmark of human social intelligence, yet the reasoning processes involved in norm formation have been difficult to capture with traditional modeling frameworks. We developed a computational model of norm formation as joint planning via theory-of-mind. The model is designed to capture the distinctively human ability to flexibly develop more complex norms in more complex situations, via simulation of joint decision-making with other agents over an extended time horizon. We evaluated the predictions of the model against participant interactions in a 2-player iterated decision-making task. Across 3 conditions our model captured the way participants balanced joint reward, fairness, and complexity when forming norms.","language":null,"license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Group Behaviour; Reasoning; Social cognition; Theory of Mind; Computational Modeling"}],"section":"Papers with Oral Presentation","is_remote":true,"remote_url":"https://escholarship.org/uc/item/12x6k20p","frozenauthors":[{"first_name":"Dhara","middle_name":"","last_name":"Yu","name_suffix":"","institution":"University of California, Berkeley","department":""},{"first_name":"Bill","middle_name":"","last_name":"Thompson","name_suffix":"","institution":"University of California, Berkeley","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2024-01-01T19:00:00+01:00","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/21518/galley/11117/download/"},{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/21518/galley/14594/download/"},{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/21518/galley/21442/download/"}]}
