Averaged F₀ traces for each attentional load condition.

<p>Time zero represents the onset of the feedback perturbation.</p

Mean response accuracy for white letter identification during low, intermediate, and high attentional load.

<p>Error bars represent standard error.</p

Block-order specific F₀ traces for each attentional load condition.

<p>Left: single-task first block-order; averaged F₀ traces for the single-task, and dual-task low, intermediate, and high attentional load conditions. Right: dual-task first block-order; averaged F₀ traces for the single-task, and dual-task low, intermediate, and high attentional load conditions. Time zero on both graphs represents the onset of the feedback perturbation.</p

ERP waveforms averaged across all electrode sites for each attentional load condition.

<p>The six averaged electrode sites are: F3, C3, Fz, Cz, F4 and C4. Time zero represents the onset of the feedback perturbation.</p

Mean “X”-placement accuracy during low, intermediate, and high attentional load.

<p>“X”-placement refers to whether the second target (“X”) in the RSVP was presented before or after the white letter. Error bars represent standard error.</p

Mean N1 amplitudes for the each electrode site.

<p>The left electrode site is the average of the F3 and C3 electrodes; the medial electrode site is the average of the Fz and Cz electrodes; and right electrode site is the average of the F4 and C4 electrodes. Error bars represent standard error.</p
