{"pk":27455,"title":"Convincing Conversations:\nUsing a Computer-Based Dialogue System to Promote a Plant-Based Diet","subtitle":null,"abstract":"In this study, we tested the effectiveness of a computer-based\npersuasive dialogue system designed to promote a plant-based\ndiet. The production and consumption of meat and dairy has\nbeen shown to be a major cause of climate change and a\nthreat to public health, bio-diversity, animal rights and human\nrights. A system promoting plant-based diets was developed,\ncomprising conversational, motivational and argumentational\nelements. 280 participants were randomly assigned to one of\nfour conditions, each representing a particular combination of\nmotivational and argumentational modules. Male participants\nshowed higher intention scores in the motivational conditions\ncompared to the argumentation-only or control condition.\nFemale participants scored higher overall, unaffected by\ncondition. These results suggest that men and women are\ndifferentially sensitive to persuasive strategies regarding the\nadoption of a plant-based diet. It seems to be particularly\nworthwhile to use motivational - as opposed to merely\nargumentational - elements in a persuasive conversation","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"human-machine interaction; dialogue system;\npersuasive communication; cognitive dissonance;\nmotivational interviewing."}],"section":"Posters: Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/7968760m","frozenauthors":[{"first_name":"Emma","middle_name":"L.","last_name":"Zaal","name_suffix":"","institution":"University of Groningen","department":""},{"first_name":"Gregory","middle_name":"J.","last_name":"Mills","name_suffix":"","institution":"University of Groningen","department":""},{"first_name":"Afke","middle_name":"","last_name":"Hagen","name_suffix":"","institution":"University of Groningen","department":""},{"first_name":"Carlijn","middle_name":"A.","last_name":"Huisman","name_suffix":"","institution":"University of Groningen","department":""},{"first_name":"John","middle_name":"C.J.","last_name":"Hoeks","name_suffix":"","institution":"University of Groningen","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2017-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27455/galley/17091/download/"}]}
