Expected Spearman correlations between all ANS measures based on mathematical considerations (in bold) and the assumption that accuracy and RT correspond in assessing ANS acuity.
We investigated the associations between young children’s domain-general executive functioning (EF) skills and domain-specific spontaneous focusing on number (SFON) tendencies and their performance on
Each of the 16 comparison pairs contained a reference numerosity (either 16 or 32 dots) and a deviant numerosity (either between 12 and 20 or between 24 and 40 dots).
Humans and other species share a perceptual mechanism dedicated to the representation of approximate quantities that allows to rapidly and reliably estimate the numerosity of a set of objects: an Appr
