The basic responses of the eyes’ pupils are well known: pupils constrict (become smaller) when you look at something bright or nearby; and pupils dilate (become larger) when you get aroused, or exert mental or physical effort. But, as the articles in this research collection show, pupil size reflects cognition in even more intricate ways: working memory, visual attention, visual awareness, mind wandering, awareness of mistakes, and individual differences—all these cognitive processes can be tracked by simply measuring the size of the pupil.
