{"pk":27521,"title":"Hierarchical Processing of Response Production and Categorisation","subtitle":null,"abstract":"Early research on categorisation suggested that verbalizable and nonverbalizable category-learning are qualitativelydifferent. Toward this end, the implementational-level model (COVIS–COmpetition between Verbal and Implicit Systems) ofcategorisation assumes that category-learning involves separate but parallel sub-systems. Specifically, for verbalizable tasksabstract category-labels are learned by a hypothesis-testing sub-system, while for nonvertbalizable tasks response position islearned by a procedural-learning sub-system. However, recent research has revealed that: 1) regardless of category structure,reversal learning is easier than learning novel categories; 2) qualitative difference between verbalizable and nonverbalizabletasks disappears when automaticity has developed; and 3) control of automatic categorisation is different from both proposedsub-systems. These challenges suggest a fundamental revision of the mechanisms of categorisation. Contrary to the separate,parallel-processing sub-systems theory, we argue that categorisation involves hierarchical-processing sub-systems of response-production and category-label association. This framework, when combined with Supervisory Attentional System theory, mayfacilitate the unification of human categorisation.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Posters: Member Abstracts","is_remote":true,"remote_url":"https://escholarship.org/uc/item/9km9s8gx","frozenauthors":[{"first_name":"Liusha","middle_name":"","last_name":"He","name_suffix":"","institution":"University of London, London","department":""},{"first_name":"Rick","middle_name":"","last_name":"Cooper","name_suffix":"","institution":"University of London, London","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2017-01-02T02:00:00+08:00","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27521/galley/17157/download/"}]}
