{"pk":26584,"title":"From computation to automization: How practice alters initial neural response tofamiliar arithmetic problems","subtitle":null,"abstract":"Building and validating models of skill acquisition that explain speedup effects has been limited by difficulty dis-tinguishing quickly executed cognitive processes (e.g. Anderson, 1982; Logan, 1988; Rickard, 1997). In this experiment,magnetoencephalography (MEG) data are collected from participants solving a repeated math problem set. We use MEG signalto test the three-phase model of skill acquisition that describes the transition from problem-solving strategies of computation,to retrieval, to an automatic stimulus-response process (Fitts & Posner, 1967). We hypothesize that the processes of familiarityand recollection are early features that distinguish the three phases of skill acquisition. Analyzing event-related fields, we testtwo predictions. First, early frontal activation (akin to the FN400 old-new effect of ERP studies) should diminish in strengthwith each successive phase transition. Second, parietal activation (corresponding to the ERP P600 old-new effect) should bepresent in the second phase, but not in the first or last phase.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[],"section":"Member Abstracts","is_remote":true,"remote_url":"https://escholarship.org/uc/item/5352z1tx","frozenauthors":[{"first_name":"Caitlin","middle_name":"","last_name":"Tenison","name_suffix":"","institution":"Carnegie Mellon University","department":""},{"first_name":"John","middle_name":"","last_name":"Anderson","name_suffix":"","institution":"Carnegie Mellon University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2016-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/26584/galley/16220/download/"}]}
