Simultaneous tDCS and Computerised Gamified Short-term Memory Task Feasibility

"The STM task will be combined with respectively two times active tDCS and one sham tDCS. The 3 conditions will be randomised, and both scientific staff and participants will be blinded.~Participants will perform the STM task on a tablet for 45 min. Headsets will deliver the tDCS. Two different placements will be used for the active stimulations: 1) F3 and PZ, and 2) F4 and PZ. The current output range will be 1.6mA and the stimulation will last for 30 min. The sham stimulation will function as a control condition. During the sham stimulation, the current density will be ramped up for 15 sec until the current reaches a density of 1.6mA for 60 sec and then again ramped down for 15 sec.~After the session, participants will fill out a brief questionnaire regarding their experience.~The time interval between sessions will be 1-3 weeks."
