      abstract     = {Working memory (WM) performance depends on the ability to
                      extract relevant while inhibiting irrelevant information
                      from entering the WM storage. This distractor inhibition
                      ability can be trained and is known to induce transfer
                      effects on WM performance. Here we asked whether transfer on
                      WM can be boosted by transcranial direct current stimulation
                      (tDCS) during a single-session distractor inhibition
                      training. As WM performance is ascribed to the
                      frontoparietal network, in which prefrontal areas are
                      associated with inhibiting distractors and posterior
                      parietal areas with storing information, we placed the anode
                      over the prefrontal and the cathode over the posterior
                      parietal cortex during a single-session distractor
                      inhibition training. This network-oriented stimulation
                      protocol should enhance inhibition processes by shifting the
                      neural activity from posterior to prefrontal regions. WM
                      improved after a single-session distractor inhibition
                      training under verum stimulation but only in subjects with a
                      high WM capacity. In subjects with a low WM capacity, verum
                      tDCS reduced the transfer effects on WM. We assume tDCS to
                      strengthen the frontostriatal pathway in individuals with a
                      high WM capacity leading to efficient inhibition of
                      distractors. In contrast, the cathodal stimulation of the
                      posterior parietal cortex might have hindered usual
                      compensational mechanism in low capacity subjects, i.e.
                      maintaining also irrelevant information in memory. Our
                      results thus stress the need to adjust tDCS protocols to
                      well-founded knowledge about neural networks and individual
                      cognitive differences.},
