Testing Steps:
The participant was asked to complete an experimental task to test their working memory performance. This was a 3-back task where the participant sees a series of letters and must identify when the letter shown is the same as the letter seen 3 letters ago. Therefore, they continuously have to identify a new set of three letters. During this task they wear an EEG headcap to obtain measurements of brain activation according to brain region.
During this step the participant receives either stimulation or sham conditions while wearing the tDCS device.
Stimulation: Current at 1.6mA for ~8 minutes
Sham: Current at 0.1mA for ~8min
The participant completes the experimental task again while wearing the EEG headcap. The accuracy of the experimental task performance and the EEG data collected are compared to the results of step 1.
Devices Used:
tDCS Stimulation: ActivaDose tDCS Starter Kit by Caputron
EEG Data Collection: BioSemi EEG headcap with 64 channels
