We found that, with the increase in visual working memory cognitive load, accuracy and reaction times in the single visual 3-back task and dual visual 3-back + auditory Go/NoGo task showed highly significant differences (accuracy: t (86) = 3.750, p < 0.001, r pb 2 = 0.141; reaction time: t (86) = −2.675, p < 0.001, r pb 2 = 0.077) (see Figure 4 a,b).
