Experimental procedure. Eighteen study-test cycles were conducted, each
consisting of a study phase, a distractor phase, and a test phase. In the study phase, 12
words per list were presented visually one after another in the center of the screen. In
the distractor phase, participants counted backward in steps of threes. In the test phase,
a cued-recall test was conducted in which item retrieval was cued with item-specific
first-letter probes. Participants were instructed to give their oral response only after
appearance of the question mark. EEG data was collected in the test phase
