An Introduction to the Approximate Number System. [PDF]
Child Dev Perspect, 2018 Abstract What are young children's first intuitions about numbers and what role do these play in their later understanding of mathematics? Traditionally, number has been viewed as a culturally derived breakthrough occurring relatively recently in human history that requires years of education to master. Contrary to this view, research

A rational analysis of the approximate number system. [PDF]
Psychon Bull Rev, 2016 It is well-known in numerical cognition that higher numbers are represented with less absolute fidelity than lower numbers, often formalized as a logarithmic mapping. Previous derivations of this psychological law have worked by assuming that relative change in physical magnitude is the key psychologically-relevant measure (Fechner, 1860; Sun et al ...

Young Children Intuitively Divide Before They Recognize the Division Symbol
Frontiers in Human Neuroscience, 2022 Children bring intuitive arithmetic knowledge to the classroom before formal instruction in mathematics begins. For example, children can use their number sense to add, subtract, compare ratios, and even perform scaling operations that increase or ...

Developmental Change of Approximate Number System Acuity (Keenness) Reveals Delay
Journal of Business and Social Review in Emerging Economies, 2021 The ability to process numbers approximately also called, approximate number system (ANS) is related and predictive of school mathematics performance. This system is functional since birth and continue to become more precise throughout the development ...

Indexing the approximate number system [PDF]
Acta Psychologica, 2014 Much recent research attention has focused on understanding individual differences in the approximate number system, a cognitive system believed to underlie human mathematical competence. To date researchers have used four main indices of ANS acuity, and have typically assumed that they measure similar properties. Here we report a study which questions

Numerosities and Other Magnitudes in the Brains: A Comparative View
Frontiers in Psychology, 2021 The ability to represent, discriminate, and perform arithmetic operations on discrete quantities (numerosities) has been documented in a variety of species of different taxonomic groups, both vertebrates and invertebrates.

Stimulus frequency alone can account for the size effect in number comparison
Acta Psychologica, 2023 In a number comparison task, the size effect (i.e, smaller values are easier to compare than larger values) is usually attributed to a psychophysics-based representation.

A Domain-General Sense of Confidence in Children [PDF]
Open Mind, 2018 Our minds constantly evaluate the confidence in what we see, think, and remember. Previous work suggests that confidence is a domain-general currency in adulthood, unifying otherwise independent sensory and perceptual representations.

The effect of language on the approximate number system.
, 2022 The approximate number system (ANS) underlies our rapid and intuitive sense for quantities (Feigenson et al., 2004). The ANS, tapped into when performing rapid number judgement (DeWind et al., 2015), is affected by the properties of visual stimuli (e.g., object density and grouping).
