{"pk":33058,"title":"Developing Object Permanence: A Connectionist Model","subtitle":null,"abstract":"When tested on siuprise or preferential looking tasks, young \ninfants show an understanding that objects continue to exist \neven though they are no longer directly perceivable. Only later \ndo infants show a similar level of competence when tested on \nretrieval tasks. Hence, a developmental lag is apparent \nbetween infants' knowledge as measured by passive response \ntasks, and their ability to demonstrate that knowledge in an \nactive retrieval task. W e jwesent a connectionist model which \nlearns to track and initiate a motor response towards objects. \nThe model exhibits a capacity to maintain a representation of \nthe object even when it is no longer directly perceptible, and \nacquires implicit tracking competence before the ability to initiate a manual response to a hidden object. A study with \ninfants confirms the model's prediction concerning improved \ntracking performance at higher object velocities. It is suggested that the developmental lag is a direct consequence of \nthe need to co-ordinate representations which themselves \nemerge through learning.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"17","is_remote":true,"remote_url":"https://escholarship.org/uc/item/2h90974t","frozenauthors":[{"first_name":"Denis","middle_name":"","last_name":"Mareschal","name_suffix":"","institution":"Oxford University","department":""},{"first_name":"Kim","middle_name":"","last_name":"Plunkett","name_suffix":"","institution":"Oxford University","department":""},{"first_name":"Paul","middle_name":"","last_name":"Harris","name_suffix":"","institution":"Oxford University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"1995-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/33058/galley/24119/download/"}]}
