Using incidental learning, this study investigated whether these brain oscillatory subsequent memory effects can be differentiated by encoding task. One group of subjects studied material performing a semantic (deep) encoding task, whereas the other group studied the same material performing a nonsemantic (shallow) encoding task. Successful encoding in the semantic task was related to power decreases in the alpha (8–12 Hz) and beta (12–20 Hz) frequency band, and a power increase in the gamma band (55–70 Hz). In the shallow task, successful encoding was related to a power decrease in the alpha band and a power increase in the theta frequency band (4–7 Hz). A direct comparison of results between the 2 encoding tasks revealed that semantic subsequent memory effects were specifically reflected by power decreases in the beta (0.5–1.5 s) and the alpha frequency band (0.5–1.0 s), whereas nonsemantic subsequent memory effects were specifically reflected by a power increase in the theta frequency band (0.5–1.0 s).</dcterms:abstract> <dc:creator>Bäuml, Karl-Heinz</dc:creator> <dcterms:bibliographicCitation>Publ. in: Cerebral cortex ; 19 (2009), 7. - S. 1631-1640</dcterms:bibliographicCitation> <dc:creator>Hanslmayr, Simon</dc:creator> </rdf:Description> </rdf:RDF>
