Frontiers in Human Neuroscience, 2021 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 Approximate Number System (ANS).

Frontiers in Education, 2021 The approximate number system (ANS) theory and the ANS mapping account have been the most prominent theories on non-symbolic numerosity processing and symbolic number processing respectively, over the last 20Â years.

THE DIFFERENTIATION OF RESPONSE NUMEROSITIES IN THE PIGEON [PDF]
Journal of the Experimental Analysis of Behavior, 2007 Two experiments examined how pigeons differentiate response patterns along the dimension of number. In Experiment 1, 5 pigeons received food after pecking the left key at least N times and then switching to the right key (Mechner's Fixed Consecutive Number schedule). Parameter N varied across conditions from 4 to 32.

Visual sense of number vs. sense of magnitude in humans and machines
Scientific Reports, 2020 Numerosity perception is thought to be foundational to mathematical learning, but its computational bases are strongly debated. Some investigators argue that humans are endowed with a specialized system supporting numerical representations; others argue ...

Nature Communications, 2022 The authors show that spatial frequency domain Fourier power closely but nonlinearly follows numerosity, simplifying computing numerosity from early visual responses.

Numerosity perception is tuned to salient environmental features
iScience, 2022 Summary: Numerosity perception is a key ability to guide behavior. However, current models propose that number units encode an abstract representation of numerosity regardless of the non-numerical attributes of the stimuli, suggesting rather coarse ...

Anisotropy of perceived numerosity: Evidence for a horizontal–vertical numerosity illusion
Acta Psychologica, 2020 Many studies have investigated whether numerical and spatial abilities share similar cognitive systems. A novel approach to this issue consists of investigating whether the same perceptual biases underlying size illusions can be identified in numerical estimation tasks.

Numerosity sense correlates with fluent mathematical abilities
Acta Psychologica, 2022 Although a great deal of research has shown a relationship between numerosity sense and mathematical ability, some studies have failed to do so. The main source of this inconsistency could be the varied ways of measuring mathematical abilities.

The role of visual information in numerosity estimation.
PLoS ONE, 2012 Mainstream theory suggests that the approximate number system supports our non-symbolic number abilities (e.g. estimating or comparing different sets of items).

Single judgments of numerosity [PDF]
Perception & Psychophysics, 1982 In previous studies, subjects generally underestimated the number of elements present in a display. To eliminate the range and intertrial effects that arise when several displays are judged in succession and that might have produced the underestimation, subjects in the present study judged only a single display.
