About

Investigation of how a single session of an attentional filter exercise of distractor inhibition combined with tDCS modulates cognitive functions like working memory, decision making and attentional control.

Full description

The study is designed as a between subject design with two groups defined by real or sham tDCS. The distractor inhibition exercise is conducted under either sham or real tDCS. Cognitive performance is assessed pre and post tDCS application, complemented by a short-termed follow-up on a consecutive day. Interindividual working memory capacity at baseline is taken into consideration.
