{"pk":31740,"title":"Modeling Property Intercorrelations in Conceptual Memory","subtitle":null,"abstract":"Behavioral experiments have demonstrated that people\nencode knowledge of correlations among semantic prop-\nerties of entities and that this knowledge influences per-\nformance on semantic tasks (McRae, 1992; McRae, de Sa,\n& Seidenberg, 1993). Independently, in connectionist the-\nory, it has been claimed that relationships among seman-\ntic properties may provide structure that is required for\nthe relatively arbitrary mapping from word form to word\nmeaning (Hinton&Shallice, 1991). W e explored these is-\nsues by implementing a modified Hopfield network (1982,\n1984) to simulate the computation from word form to\nmeaning. The model was used as a vehicle for developing\nexplanations for the role played by correlated properties in\ndetermining short interval semantic priming effects and in\ndetermining the ease with which a property is verified as\npart of a concept. Simulations of the priming and property\nverification experiments of McRae (1992) are reported. It\nis concluded that correlations among properties encoded\nin conceptual memory play a key role in the dynamics of\nthe computation of word meaning. Furthermore, a model\nin which property intercorrelations are central to forming\nbasins of attraction corresponding to concepts may pro-\nvide important insights into lexical memory.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Submitted Presentations","is_remote":true,"remote_url":"https://escholarship.org/uc/item/7qz0j3qj","frozenauthors":[{"first_name":"Ken","middle_name":"","last_name":"Mcrae","name_suffix":"","institution":"University of Rochester","department":""},{"first_name":"Virginia","middle_name":"R .","last_name":"de Sa","name_suffix":"","institution":"University of Rochester","department":""},{"first_name":"Mark","middle_name":"S.","last_name":"Seidenberg","name_suffix":"","institution":"University of Southern California Los Angeles","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"1993-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/31740/galley/22808/download/"}]}
