Previous research has shown that in enumeration tasks, "subitizing" is a rapid and an accurate process used with 1-4 items, and that "counting" is a slow and an inaccurate process used with over four items. It has been suggested that the former task is preattentive, whereas the latter task is attentive. We investigated whether item-size invariance and pattern symmetry affected subitizing and counting speeds. Participants enumerated dots, which were continuously presented, as quickly and as… CONTINUE READING
