Overview of the experimental design. (A) General structure of the Hebb paradigm as used in this study. One memory set, the Hebb set, is presented repeatedly among nonrepeated filler sets. The Hebb set appeared, on average, every fourth trial. (B) Flow of a trial in the visual Hebb experiment. (C) Flow of a trial in the verbal Hebb experiment. Note that in the actual experiment, the upcoming memory-list boxes were empty.
