An overview of the study procedure. Each of the three sessions consisted of encoding, consolidation, and retrieval. The retrieval was repeated after 24 h via an online survey. The baseline measurement (cognitive screening, paired associates test) was completed in the first session. Transcranial electric stimulation (tES) was applied during encoding. Different questionnaires (Qu) were given before the encoding and during the retention phase.
