{"pk":27871,"title":"Emergence of vowel-like organization in a color-based communicatino system","subtitle":null,"abstract":"Vowel systems exhibit organization, and several theoretical ac-counts have been proposed to explain this. A prominent ac-count explains organization in terms of maximizing the disper-sion of vowels, increasing acoustic perceptibility while reduc-ing articulatory effort. This implies modality-independence,but leaves open questions about the extent to which dispersionis driven by articulatory or acoustic pressures. We investigatedwhether vowel-like organization would emerge in a novel vi-sual communication system in the laboratory, in which partic-ipants took turns to send color signals to communicate a set ofanimal referents by moving their fingers around a color space.We manipulated the extent to which sender and receiver needswere aligned. Overall, systems exhibited significant levels ofdispersion; participants also took into account receiver needs,withconsequences for the structure of the resulting systems.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Language"},{"word":"Phonology"},{"word":"experimental"},{"word":"Communication game"},{"word":"Experimental semiotics"}],"section":"Publication-based-Talks","is_remote":true,"remote_url":"https://escholarship.org/uc/item/9vn6518t","frozenauthors":[{"first_name":"Gareth","middle_name":"","last_name":"Roberts","name_suffix":"","institution":"UPenn","department":""},{"first_name":"Robin","middle_name":"","last_name":"Clark","name_suffix":"","institution":"UPenn","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2018-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27871/galley/17509/download/"}]}
