Humans perceptually extract quantity information from our environments, be it from simple
stimuli in isolation, or from relational magnitudes formed by taking ratios of pairs of simple …

A fundamental question about fractions is whether they are grounded in an abstract
nonsymbolic magnitude code similar to that postulated for whole numbers. Mounting …

What do numerical estimates tell us about developing an understanding of number? One
theory is that bounded number line estimation (NLE) tasks reveal a “representational shift” …

The number line estimation task is frequently used to measure children's numerical
magnitude understanding. It is unclear whether the resulting straight, horizontal, left‐to‐right …

Intuitive statistical inferences refer to making inferences about uncertain events based on
limited probabilistic information, which is crucial for both human and non-human species' …

It has long been known that people have the ability to estimate numerical quantities without
counting. A standard account is that people develop a sense of the size of symbolic numbers …

Humans tend to be inaccurate and inconsistent when estimating a large number of objects.
Furthermore, we modify our estimates when feedback or a reference array is provided …

Fractions knowledge is widely recognized as a key building block for developing
mathematical competence. However, many children face difficulties learning fractions …

A substantial body of research has found that human and nonhuman animals are capable of
processing the magnitudes of nonsymbolic ratios. Lewis, Mathews and Hubbard (2015) …

Perceptual judgments result from a dynamic process, but little is known about the dynamics
of number‐line estimation. A recent study proposed a computational model that combined a …
