{"pk":31977,"title":"Selective attention in the acquisition of the past tense","subtitle":null,"abstract":"It is well known that children generally exhibit a \"U-shaped\" pattern of development in the process of acquiring the past tense. Piunkett & Marchman (1991) showed that a connectionist network, trained on the past tense, would exhibit U-shaped learning effects. This network did not completely master the past tense mapping, however. Piunkett & Marchman (1993) showed that a network trained with an incrementally expanded training set was able to achieve acceptable levels of mastery, as well as show the desired U-shaped pattern. In this paper, we point out some problems with using an incrementally expanded training set. We propose a model of selective attention that enables our network to completely master the past tense mapping and exhibit U-shaped learning effects without requiring external manipulation of its training set.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Paper Presentations","is_remote":true,"remote_url":"https://escholarship.org/uc/item/20p9b3xd","frozenauthors":[{"first_name":"Dan","middle_name":"","last_name":"Jackson","name_suffix":"","institution":"University of California, San Diego","department":""},{"first_name":"Rodger","middle_name":"M.","last_name":"Constandse","name_suffix":"","institution":"Institute for Neural Computation, University of California, San Diego","department":""},{"first_name":"Garrison","middle_name":"W.","last_name":"Cottrell","name_suffix":"","institution":"Institute for Neural Computation, University of California, San Diego","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"1996-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/31977/galley/23042/download/"}]}
