      <dc:description>Maintaining vigilance is essential for many everyday tasks, but over time, our ability to sustain it&#xd;
inevitably decreases, potentially entailing severe consequences. High-definition transcranial direct&#xd;
current stimulation (HD-tDCS) has proven to be useful for studying and improving vigilance. This study&#xd;
explores if/how cognitive load affects the mitigatory effects of HD-tDCS on the vigilance decrement.&#xd;
Participants (N = 120) completed a modified ANTI-Vea task (single or dual load) while receiving either&#xd;
sham or anodal HD-tDCS over the right posterior parietal cortex (rPPC). This data was compared with&#xd;
data from prior studies (N = 120), where participants completed the standard ANTI-Vea task (triple&#xd;
load task), combined with the same HD-tDCS protocol. Against our hypotheses, both the single and&#xd;
dual load conditions showed a significant executive vigilance (EV) decrement, which was not affected&#xd;
by the application of rPPC HD-tDCS. On the contrary, the most cognitively demanding task (triple&#xd;
task) showed the greatest EV decrement; importantly, it was also with the triple task that a significant&#xd;
mitigatory effect of the HD-tDCS intervention was observed. The present study contributes to a more&#xd;
nuanced understanding of the specific effects of HD-tDCS on the vigilance decrement considering&#xd;
cognitive demands. This can ultimately contribute to reconciling heterogeneous effects observed in&#xd;
past research and fine-tuning its future clinical application.</dc:description>
