{"pk":49470,"title":"Base Rate Neglect in Linguistic Category Learning","subtitle":null,"abstract":"This paper presents a categorization experiment supporting the hypothesis that base-rate-neglect occurs in linguistic category learning (and, thus, is a cross-domain phenomenon), and that it is more likely for those learners who engage in explicit problem-solving, rather than implicit learning. We find that among those participants who were able to verbalize the cue that was probabilistically associated with category-membership (correct-staters) in a phonological learning task, about a third respond in a way consistent with base-rate-neglect. On the other hand, non-staters are more likely to respond randomly or by probability matching the base-rates. These results suggest that explicit learning is associated with base-rate-neglect to a greater extent. We found that no learners integrate the two probabilistic patterns present in the experiment into a single Bayesian estimate. Rather, some of them focus on the base-rates, others focus on category-internal cues, and others simply fail to learn anything.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Linguistics; Psychology; Concepts and categories; Decision making; Phonology"}],"section":"Papers with Poster Presentation","is_remote":true,"remote_url":"https://escholarship.org/uc/item/6nf8q6dp","frozenauthors":[{"first_name":"Katya","middle_name":"","last_name":"Pertsova","name_suffix":"","institution":"University of North Carolina, Chapel Hill","department":""},{"first_name":"Elliott","middle_name":"","last_name":"Moreton","name_suffix":"","institution":"UNC, Chapel Hill","department":""},{"first_name":"Josh","middle_name":"","last_name":"Fennell","name_suffix":"","institution":"Fizz Studio","department":""},{"first_name":"Brandon","middle_name":"","last_name":"Prickett","name_suffix":"","institution":"UMass","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2025-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/49470/galley/37432/download/"}]}
