Abstract
Subitizing and visual short-term memory in human and non-human species: a common shared system?
Highlights
Several species show a fast and accurate performance in judging the numerosity of small sets of items, an ability termed “subitizing” (Tomonaga and Matsuzawa, 2002; Agrillo et al, 2012)
A challenging question is whether these similarities in nonsymbolic numerical information processing are due to numerical competences or if they are caused by the limits of the systems devoted to the processing of visual sets of items
VSTM can retain a limited amount of information at one time and, in humans, it is typically investigated by means of change detection paradigms
Summary
Several species show a fast and accurate performance in judging the numerosity of small sets of items, an ability termed “subitizing” (Tomonaga and Matsuzawa, 2002; Agrillo et al, 2012). A challenging question is whether these similarities in nonsymbolic numerical information processing are due to numerical competences or if they are caused (in both human and non-human species) by the limits of the systems devoted to the processing of visual sets of items (visual short-term memory, VSTM).
