{"pk":27184,"title":"Compound effects of expectations and actual behaviors in human-agentinteraction: Experimental investigation using the Ultimatum Game","subtitle":null,"abstract":"This study investigated how the expectations of others (i.e.,top-down processes) and actual perceived behavior (i.e.,bottom-up processes) influence negotiations during human-agent interactions. Participants took part in several sessions ofthe ultimatum game; we investigated the bargaining strategiesdirected toward the computer agent. To investigate the influ-ence of top-down and bottom-up processes on performance,we designed an experiment wherein (1) participants expectedtheir partners were humans or agents, and (2) agents used dif-ferent types of algorithmic behavior. Results revealed that ir-rational decisions, which are characteristic of human-humaninteractions, emerged when participants believed their oppo-nents were human and when opponent behaviors were ambigu-ous. Further, we found participants adopted different bargain-ing strategies according to their expectations and the agent’sspecific algorithmic behavior. We discuss interplay of the twotypes of cognitive processing in human-agent interaction.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"human-agent interaction; top-down/bottom-upprocesses; social interaction; ultimatum game"}],"section":"Posters: Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/72t3c633","frozenauthors":[{"first_name":"Yugo","middle_name":"","last_name":"Hayashi","name_suffix":"","institution":"Ritsumeikan University","department":""},{"first_name":"Ryo","middle_name":"","last_name":"Okada","name_suffix":"","institution":"Ritsumeikan University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2017-01-01T13:00:00-05:00","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27184/galley/16820/download/"}]}
