FIGURE 1.

Example of stimuli and experimental design of the working memory (WM) tasks (n-back). In the face 0-back task, participants were asked to judge whether or not the face stimulus was female. In the location 0-back task, participants were asked to judge whether or not the dot was located in the center of the screen. In the 1-back task, participants were asked to judge whether or not the test item was identical to the one immediately preceding it (i.e., the face or the location of the dot presented in the last trial). Written consent was obtained from the individuals for the publication of their face images.
