An example of the experimental tasks and analysis. The experiment consisted of theme or sex identification for consecutively presented pictures. During theme identification (A1), participants were asked to select the theme word. In this example, “Wedding” was the theme word, “Bride” was the related word, and “Earring” was the unrelated word. During sex identification (A2), participants were asked to select the sex of the people in the picture. In the analysis (B), a heat map was automatically revealed by the eye tracker, and the area of interest (AOI) was defined as the area that healthy controls had viewed for more than 50 ms (colored dark red on the heat map).
