{"pk":30210,"title":"Effect of a colour-based descriptor and stimuli presentation mode in unsupervisedcategorization","subtitle":null,"abstract":"In unsupervised categorization, studies have shown that fewer stimuli dimensions are used for categorization with serialpresentation compared to concurrent presentation of stimuli. In this study, we investigate how a colour-based multidimen-sional descriptor might affect the number of dimensions used in categorization. Our results show that a fewer numberof dimensions are used when stimuli are presented serially irrespective of the presence of a colour-based descriptor. Wefound main effects for both the stimuli presentation mode and the colour-based descriptor. The stimuli has the same logicalstructure across all the conditions. Our results show that the notion of a natural and intuitive grouping of items is affectedby meta-level feature descriptors, that are not part of a feature-based representation of stimuli. We discuss the implica-tions of our findings for computational models of categorization, which make predictions based solely on feature-basedrepresentation of stimuli.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Member Abstracts, appearing in proceedings only","is_remote":true,"remote_url":"https://escholarship.org/uc/item/4m9134gw","frozenauthors":[{"first_name":"Sujith","middle_name":"","last_name":"Thomas","name_suffix":"","institution":"Birla Institute of Technology Goa Campus","department":""},{"first_name":"Aditya","middle_name":"","last_name":"Kapoor","name_suffix":"","institution":"Birla Institute of Technology Goa Campus","department":""},{"first_name":"Narayanan","middle_name":"","last_name":"Srinivasan","name_suffix":"","institution":"University of Allahabad","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2020-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/30210/galley/20064/download/"}]}
