Calibrating the mental number line [PDF]
Cognition, 2008 Human adults are thought to possess two dissociable systems to represent numbers: an approximate quantity system akin to a mental number line, and a verbal system capable of representing numbers exactly. Here, we study the interface between these two systems using an estimation task.

Multiplication facts and the mental number line: evidence from unbounded number line estimation [PDF]
Psychological Research, 2015 A spatial representation of number magnitude, aka the mental number line, is considered one of the basic numerical representations. One way to assess it is number line estimation (e.g., positioning 43 on a number line ranging from 0 to 100). Recently, a new unbounded version of the number line estimation task was suggested: without labeled endpoints ...

Spatial–numerical associations from a novel paradigm support the mental number line account
Quarterly Journal of Experimental Psychology, 2021 Multiple tasks have been used to demonstrate the relation between numbers and space. The classic interpretation of these directional spatial–numerical associations (d-SNAs) is that they are the product of a mental number line (MNL), in which numerical ...

Children perform better on left than right targets in an ordinal task
Acta Psychologica, 2022 Francis Galton first reported that humans mentally organize numbers from left to right on a mental number line (1880). This spatial-numerical association was long considered to result from writing and reading habits.

Vertical spatial representation of numbers across two cultures [PDF]
Psihologija, 2019 There is strong evidence that numbers are spatially represented. However, much of the research has been concerned with investigating number representation within the horizontal rather than the vertical dimension.

Extra-powerful on the visuo-perceptual space, but variable on the number space: Different effects of optokinetic stimulation in neglect patients [PDF]
, 2015 We studied the effects of optokinetic stimulation (OKS; leftward, rightward, control) on the visuo-perceptual and number space, in the same sample, during line bisection and mental number interval bisection tasks. To this end, we tested six patients with

Non-spatial neglect for the mental number line [PDF]
Neuropsychologia, 2011 Several psychophysical investigations, expanding the classical introspective observations by Galton, have suggested that the mental representation of numbers takes the form of a number line along which magnitude is positioned in ascending order according to reading habits, i.e. from left to right in Western cultures.

How does working memory enable number-induced spatial biases? [PDF]
, 2016 Number-space associations are a robust observation, but their underlying mechanisms remain debated. Two major accounts have been identified. First, spatial codes may constitute an intrinsic part of number representations stored in the brain – a ...

Spatial displacement of numbers on a vertical number line in spatial neglect
Frontiers in Human Neuroscience, 2015 Previous studies that investigated the association of numbers and space in humans came to contradictory conclusions about the spatial character of the mental number magnitude representation and about how it may be influenced by unilateral spatial neglect.

Approaching stimuli bias attention in numerical space [PDF]
, 2012 Increasing evidence suggests that common mechanisms underlie the direction of attention in physical space and numerical space, along the mental number line. The small leftward bias (pseudoneglect) found on paper-and-pencil line bisection is also observed
