{"pk":27740,"title":"Tracking the Development of Automaticity in Memory Search with Human Electrophysiology","subtitle":null,"abstract":"Shiffrin and Schneider (1977) demonstrated that highly efficient\nmemory- and visual-search performance could be achieved\nthrough consistent item-to-response mapping (CM) training. It is\ntheorized that subjects shifted from relying on working memory to\nlearned item-response associations in long-term memory (Logan,\n1988). The theory was tested and explored mostly through\nbehavioral experiments and computational modeling. In a recent\nseries of articles involving visual search (e.g. Woodman et al,\n2013; Carlisle et al. 2011), Woodman and colleagues found that\nthe contralateral-delay activity (CDA) of human event-related\npotentials is related to the maintenance of information in visual\nworking memory and that the magnitude of the CDA decreases\nwhen target information is stored in long-term memory. We\nemployed the CDA and other neural measures to study the nature\nof memory retrieval in CM memory search tasks. We observed a\nsignificant reduction in the magnitude of the CDA in CM training\ncompared to a control condition in which item-response mappings\nvaried from trial to trial (VM). The results provided converging\nevidence supporting the classic theoretical interpretation of the\nbases for CM and VM memory search. The results also raised\ninteresting questions concerning the detailed interpretation of\nCDA.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"memory search"},{"word":"Old-new recognition"},{"word":"EEG"},{"word":"Automatic processing"},{"word":"contralateral delay activity"}],"section":"Publication-based-Talks","is_remote":true,"remote_url":"https://escholarship.org/uc/item/4qb622n2","frozenauthors":[{"first_name":"Rui","middle_name":"","last_name":"Cao","name_suffix":"","institution":"Indiana University","department":""},{"first_name":"Thomas","middle_name":"A","last_name":"Busey","name_suffix":"","institution":"Indiana University","department":""},{"first_name":"Robert","middle_name":"M","last_name":"Nosofsky","name_suffix":"","institution":"Indiana University","department":""},{"first_name":"Richard","middle_name":"M","last_name":"Shiffrin","name_suffix":"","institution":"Indiana University","department":""},{"first_name":"Geoffery","middle_name":"F","last_name":"Woodman","name_suffix":"","institution":"Vanderbilt University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2018-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27740/galley/17380/download/"}]}
