The main contribution consists of the interpretation of the story characters by humanoid robots, obtained through the definition of appropriate cognitive models, relying on the ACT-R cognitive architecture. The reasoning processes leading to the story evolution are based on the represented knowledge and the suggestions of the listener in critical points of the story. They are disclosed during the narration, to make clear the dynamics of the story and the feelings of the characters. We analyzed the impact of such externalization of the internal status of the characters to set the basis for future experimentation with primary school children.<\/jats:p>","DOI":"10.3390\/robotics9020025","type":"journal-article","created":{"date-parts":[[2020,4,13]],"date-time":"2020-04-13T04:45:31Z","timestamp":1586753131000},"page":"25","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["An ACT-R Based Humanoid Social Robot to Manage Storytelling Activities"],"prefix":"10.3390","volume":"9","author":[{"given":"Adriana","family":"Bono","sequence":"first","affiliation":[{"name":"Department of Engineering, University of Palermo, 90128 Palermo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Agnese","family":"Augello","sequence":"additional","affiliation":[{"name":"ICAR-CNR, Italian National Research Council, 90146 Palermo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6254-2249","authenticated-orcid":false,"given":"Giovanni","family":"Pilato","sequence":"additional","affiliation":[{"name":"ICAR-CNR, Italian National Research Council, 90146 Palermo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2502-0062","authenticated-orcid":false,"given":"Filippo","family":"Vella","sequence":"additional","affiliation":[{"name":"ICAR-CNR, Italian National Research Council, 90146 Palermo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Salvatore","family":"Gaglio","sequence":"additional","affiliation":[{"name":"Department of Engineering, University of Palermo, 90128 Palermo, Italy"},{"name":"ICAR-CNR, Italian National Research Council, 90146 Palermo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Mutlu, B., Forlizzi, J., and Hodgins, J.
