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

The Association Between Higher Education and Approximate Number System Acuity [PDF]
Frontiers in Psychology, 2014 Humans are equipped with an Approximate Number System (ANS) supporting non-symbolic numerosity representation. Studies indicate a relationship between ANS-precision (acuity) and math achievement. Whether the ANS is a prerequisite for learning mathematics

False approximations of the approximate number system? [PDF]
PLoS ONE, 2011 Prior research suggests that the acuity of the approximate number system (ANS) predicts future mathematical abilities. Modelling the development of the ANS might therefore allow monitoring of children's mathematical skills and instigate educational ...

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

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 ...

The approximate number system acuity redefined: A diffusion model approach [PDF]
Frontiers in Psychology, 2015 While all humans are capable of nonverbally representing numerical quantity using so-called the approximate number system (ANS), there exist considerable individual differences in its acuity.

To what extent is dot comparison an appropriate measure of approximate number system? [PDF]
Frontiers in Psychology, 2023 Introduction:Number sense has been systematically measured using dot comparison tasks. However, recent studies have reported that performance on dot comparison might be influenced inhibitory control and visual properties of dot arrays.

Arithmetic Training Does Not Improve Approximate Number System Acuity [PDF]
Frontiers in Psychology, 2016 The Approximate Number System (ANS) is thought to support non-symbolic representations of numerical magnitudes in humans. Recently much debate has focused on the causal direction for an observed relation between ANS acuity and arithmetic fluency. Here we

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.
