Furthermore, we observed stronger effects when tDCS was spaced over a weekend break relative to consecutive daily training, and we also demonstrated selective transfer in the right prefrontal group to nontrained tasks of visual and spatial WM. Working memory was evaluated by the backward Digit-Span Test. Results showed that tDCS enhanced training performance, which was strikingly preserved several months after training completion. No ERP effects in the physical and no-contact control groups were found, while a reduction. Sixty-two participants were randomized to receive either right prefrontal, left prefrontal, or sham stimulation with concurrent visuospatial WM training over the course of seven training sessions. This study assessed the efficacy of tDCS to supplement WM training. As such, it has the potential to boost learning and enhance performance on cognitive tasks.

3 working memory tests including Digit Span Forward and Backward plus Digit Ordering. Another promising intervention that has gained increasing traction in recent years is transcranial direct current stimulation (tDCS), a noninvasive form of brain stimulation that can modulate cortical excitability and temporarily increase brain plasticity. Relation of Loneliness to Change in Cognitive Function. Thus, WM training interventions have become very popular as a means of potentially improving WM-related skills. Working memory (WM) is a fundamental cognitive ability that supports complex thought but is limited in capacity.
