{"pk":27631,"title":"Impaired phonological processing of lexical tones in Cantonese speakers withcongenital amusia","subtitle":null,"abstract":"Congenital amusia is a lifelong musical disorder. It has been found that tonal-language speakers with amusia areimpaired in lexical tone perception. But it has also been found that tonal-language experience compensates the deficit in certainscenario, reducing prevalence rate of amusia in speakers of a highly complex tonal-language – Cantonese. Thus it remainsunclear whether lexical tone perception, especially its phonological processing, is impaired in Cantonese-speaking amusics.This study investigated the categorical perception of a continuum of lexical tone stimuli and pure tone analogues in Cantonese-speaking amusics and controls. The amusics showed reduced discrimination peak across the categorical boundary comparedto controls in lexical tone condition, suggesting impaired categorical perception; in pure tone condition, the amusics showedinferior performance on both between- and within-category discriminations, suggesting a deficit in auditory pitch processing.These findings indicate that phonological processing of tone is impaired in Cantonese-speaking amusics, despite possiblecompensation effect.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Posters: Member Abstracts","is_remote":true,"remote_url":"https://escholarship.org/uc/item/6pn9v35q","frozenauthors":[{"first_name":"Jing","middle_name":"","last_name":"Shao","name_suffix":"","institution":"The Hong Kong Polytechnic University","department":""},{"first_name":"Xunan","middle_name":"","last_name":"Huang","name_suffix":"","institution":"The Hong Kong Polytechnic University","department":""},{"first_name":"Caicai","middle_name":"","last_name":"Zhang","name_suffix":"","institution":"The Hong Kong Polytechnic University","department":""},{"first_name":"Jason","middle_name":"","last_name":"Shepard","name_suffix":"","institution":"Agnes Scott College","department":""},{"first_name":"Aiming","middle_name":"","last_name":"Nie","name_suffix":"","institution":"Stanford University","department":""},{"first_name":"Bridget","middle_name":"","last_name":"Copley","name_suffix":"","institution":"CNRS/Universite Paris 8","department":""},{"first_name":"Phillip","middle_name":"","last_name":"Wolff","name_suffix":"","institution":"Emory University","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/27631/galley/17267/download/"}]}
