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

Task Constraints Affect Mapping From Approximate Number System Estimates to Symbolic Numbers [PDF]
Frontiers in Psychology, 2018 The Approximate Number System (ANS) allows individuals to assess nonsymbolic numerical magnitudes (e.g., the number of apples on a tree) without counting.

Significant Inter-Test Reliability Across Approximate Number System Assessments [PDF]
Frontiers in Psychology, 2016 The approximate number system (ANS) is the hypothesized cognitive mechanism that allows adults, infants, and animals to enumerate large sets of items approximately. Researchers usually assess the ANS by having subjects compare two sets and indicate which

A rational analysis of the approximate number system [PDF]
Psychonomic Bulletin & Review, 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 ...

Rational Number Representation by the Approximate Number System
, 2023 The approximate number system (ANS) enables organisms to represent the approximate number of items in an observed collection, quickly and independently of natural language. Recently, it has been proposed that the ANS goes beyond representing natural numbers by extracting and representing rational numbers (Clarke & Beck 2021a).

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 ...

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 ...
