Topic: numerosity discrimination

Human infants are suggested to be born with a non-symbolic understanding of quantities. This innate ability is proposed to rely on two separate systems for numerosity discrimination: an approximate system for the representation of large (≥ 4) and a precise system for the representation of small (1–3) numerosities. However, these claims have been primarily deduced from studies in older infants, not newborns. Additionally, most of the studies have utilized behavioral designs and visual stimuli. Due to the importance of information regarding infants’ innate abilities for theories concerning the o
