FIGURE 1.

Task procedure of the (A) non-verbal learning task (NVLT) and (B) verbal learning task (VLT). After 3 s of stimulus presentation, participants were shown the stimulus and the question “Ja/Nein?” [German for “Yes/No”] for 2 s, asking them to indicate by button press whether they had seen the stimulus before. Then, a fixation cross was shown for 0.5 s. Before the next stimulus presentation, a black screen was shown for a jittered duration of 1.5–2.5 s to avoid expectation effects of the participants.
