It is now clear that most animals, including humans, possess an ability to rapidly estimate
number. Some have questioned whether this ability arises from dedicated numerosity …

Humans, including infants, and many other species have a capacity for rapid, nonverbal
estimation of numerosity. However, the mechanisms for number perception are still not clear; …

Developmental dyscalculia (DD) is a developmental learning disability that manifests as a
persistent difficulty in comprehending even the most basic numeric and arithmetic concepts …

This study focuses on parental reading and mathematical difficulties, the home literacy
environment, and the home numeracy environment as well as their predictive role in Finnish …

The ability to estimate numerosity in a visual array arose early in evolution, develops early in
human development, and is correlated with mathematical ability. Previous work with visually …

Humans and other animals base important decisions on estimates of number, and
intraparietal cortex is thought to provide a crucial substrate of this ability. However, it remains …

Psychophysical studies have shown that numerosity is a sensory attribute susceptible to
adaptation. Neuroimaging studies have reported that, at least for relatively low numbers …

Previous work has shown that when arrays of objects are grouped within clusters,
participants can enumerate their numerosity more rapidly than when objects are randomly …

Small quantities of visual objects can be rapidly estimated without error, a phenomenon
known as subitizing. Larger quantities can also be rapidly estimated, but with error, and the …

Humans and other animals are able to make rough estimations of quantities using what has
been termed the approximate number system (ANS). Much evidence suggests that …
