Figure 3From: Perceived mental effort correlates with changes in tonic arousal during attentional tasksGrand mean event-related potentials (ERPs) for parietal electrodes (P3 and P4) during the three attentional tasks. Grand mean event-related potentials (ERPs) for parietal electrodes (P3 and P4) during the three attentional tasks: continuous performance task (CPT), go/no-go task (go and no-go conditions; GNG), and cued target detection task (CTD).Back to article page
