Participants completed standard and ecologically valid far-transfer tasks during preliminary and follow-up home visits. DNA samples were collected during the preliminary home visit. Participants completed near transfer tasks on the first lab visit and follow-up lab visit; the n-Back task was completed during functional near infrared spectroscopy (fNIRS) recording. Participants received active or sham transcranial direct current stimulation (tDCS) during each lab visit, except the final lab visit. At all lab visits, participants completed working memory (WM) training tasks. Events are presented in the figure from top to bottom in the order they were administered.
