Training the approximate number system improves math proficiency. [PDF]
Psychol Sci, 2013 Humans and nonhuman animals share an approximate number system (ANS) that permits estimation and rough calculation of quantities without symbols. Recent studies show a correlation between the acuity of the ANS and performance in symbolic math throughout development and into adulthood, which suggests that the ANS may serve as a cognitive foundation for

Measuring the Approximate Number System [PDF]
Quarterly Journal of Experimental Psychology, 2011 Recent theories in numerical cognition propose the existence of an approximate number system (ANS) that supports the representation and processing of quantity information without symbols. It has been claimed that this system is present in infants, children, and adults, that it supports learning of symbolic mathematics, and that correctly harnessing ...

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 ...

The Role of Approximate Number System in Different Mathematics Skills Across Grades [PDF]
Frontiers in Psychology, 2018 Although approximate number system (ANS) has been found to predict mathematics ability, it remains unclear if both aspects of ANS (symbolic and non-symbolic estimation) contribute equally well to mathematics performance and if their contribution varies ...

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 ...

Are there rapid feedback effects on Approximate Number System acuity? [PDF]
Frontiers in Human Neuroscience, 2013 Humans are believed to be equipped with an Approximate Number System (ANS) that supports non-symbolic representations of numerical magnitude. Correlations between individual measures of the precision of the ANS and mathematical ability have raised the ...

Relation between approximate number system acuity and mathematical achievement: The influence of fluency [PDF]
Frontiers in Psychology, 2016 Previous studies have observed inconsistent relations between the acuity of the Approximate Number System (ANS) and mathematical achievement. In this paper, we hypothesize that the relation between ANS acuity and mathematical achievement is influenced by

Malleability of the approximate number system: effects of feedback and training [PDF]
Frontiers in Human Neuroscience, 2012 Prior research demonstrates that animals and humans share an approximate number system (ANS), characterized by ratio dependence and that the precision of this system increases substantially over human development. The goal of the present research was to
