Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants engage in five treatment sessions on consequent week days. Each session comprises cognitive training coupled with active or sham transcranial direct current stimulation (tDCS). Specifically, participants are randomised to one of the following intervention conditions:

a) cognitive control training + anodal tDCS (2mA)
b) cognitive control training + sham tDCS
c) peripheral vision training + anodal tDCS (2mA)

Cognitive control training comprises a set of computerised thinking tasks designed to engage the dorsolateral prefrontal cortex region of the brain. The peripheral vision training comprises a set of computerised thinking tasks designed to engage the visual cortex to a great degree than the dorsolateral prefrontal cortex.

Both types of training will be administered concurrently with active/sham tDCS throughout five 24-minute treatment sessions.
