{"pk":21462,"title":"Hybrid-Similarity Exemplar Model of Context-Dependent Memorability","subtitle":null,"abstract":"We conduct tests of a hybrid-similarity exemplar model on its ability to account for the context-dependent memorability of items embedded in high-dimensional category spaces. According to the model, recognition judgments are based on the summed similarity of test items to studied exemplars. The model allows for the idea that “self-similarity” among objects differs due to matching on highly salient distinctive features. Participants viewed a study list of rock images belonging to geologically defined categories where the number of studied items from each category was manipulated, and their old-new recognition performance was then tested. With a minimum of parameter estimation, the model provided good accounts of changing levels of memorability due to contextual effects of category size, within- and between-category similarity, and the presence of distinctive features. We discuss future directions for improving upon the current predictions from the model.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Psychology; Concepts and categories; Memory; Computational Modeling; Mathematical modeling"}],"section":"Papers with Oral Presentation","is_remote":true,"remote_url":"https://escholarship.org/uc/item/3rf1n6r9","frozenauthors":[{"first_name":"Robert","middle_name":"","last_name":"Nosofsky","name_suffix":"","institution":"Indiana University","department":""},{"first_name":"Adam","middle_name":"","last_name":"Osth","name_suffix":"","institution":"University of Melbourne","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2024-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/21462/galley/11061/download/"},{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/21462/galley/21907/download/"}]}
