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.

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.

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.

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).

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.

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.

Phenomenology, Quantity, and Numerosity
Journal of Intelligence, 2023 There are many situations in which we interact with collections of objects, from a crowd of people to a bowl of blackberries. There is an experience of the quantity of these items, although not a precise number, and we have this impression quickly and effortlessly. It can be described as an expressive property of the whole. In the literature, the study

Frontiers in Human Neuroscience, 2022 There is ample evidence from literature and clinical practice indicating mathematical difficulties in individuals with ADHD, even when there is no concomitant diagnosis of developmental dyscalculia.
