Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
