Oscillatory Correlates of Selective Restudy

Prior behavioral work has shown that selective restudy of some studied items leaves recall the other unaffected when lag between study and is short, but improves prolonged. The beneficial effect been attributed to context retrieval, assuming reactivates at thus provides a retrieval cue for (Bäuml, 2019 ). Here results two experiments are reported, in each which subjects list then, after short 2-min or prolonged 10-min lag, restudied items. Participants' electroencephalography (EEG) was recorded during both phases. In Experiment 2, not 1, engaged mental reinstatement task immediately before phase started, trying mentally reinstate context. Results 1 revealed theta/alpha power increase from an alpha/beta decrease long lag. Engagement 2 eliminated power. consistent with view observed reflects became obsolete there preceding reinstatement.
