FIGURE 5.

Mean pupil diameter (MPD) and parietal alpha event related spectral perturbation (ERSP). (a) Grand‐mean MPD over time. (b) Peak MPD measure around the switch time. (c) Grand‐mean parietal alpha ERSP over time. (d) Minimum parietal alpha ERSP measure around the switch time. Experimental condition has a main effect on peak MPD and minimum parietal ERSP around the switch time. Peak MPD and minimum parietal alpha ERSP measures are different between the sustained attention and at‐will switch conditions
