While research on the spatial representation of number has provided substantial evidence for a horizontally oriented mental number line, recent studies suggest vertical organization as well. Directly comparing the relative strength of horizontal and vertical organization, however, we found no evidence of spontaneous vertical orientation (upward or downward), and horizontal trumped vertical when pitted against each other (Experiment 1). Only when numbers were conceptualized as magnitudes (as…

Mental Number Representations in 2D Space
TLDR
Results indicated that large numbers were associated with upper space more strongly than small numbers, suggesting that in two-dimensional space when no response dimension is given, numbers are conceptually associated with vertical, but not horizontal space.

Counting is a spatial process: evidence from eye movements
TLDR
It is concluded that space is not only used to represent number magnitudes but also to actively operate on numbers in more complex tasks such as counting, and that the eyes reflect this spatial mental operation.
Is more always up? Evidence for a preference of hand-based associations over vertical number mappings
ABSTRACT It has been argued that the association of numbers and vertical space plays a fundamental role for the understanding of numerical concepts. However, convincing evidence for an association of…
When Numbers Get Heavy: Is the Mental Number Line Exclusively Numerical?
TLDR
It is shown that this information is not exclusive to number, simultaneously accommodating numerical and non-numerical magnitudes, with spatial organization instantiating representational currency shared across magnitudes.
Spatial–numerical associations from a novel paradigm support the mental number line account
TLDR
Using a between-subject design, it is found that numbers, but not letters, biased participants' responses along the horizontal dimension, such that larger numbers were placed more rightward than smaller numbers, even when participants completed a concurrent verbal working memory task.
Spatial Interferences in Mental Arithmetic: Evidence from the Motion–Arithmetic Compatibility Effect
TLDR
The stronger effect of the vertical dimension supports the idea that mental calculations operate on representations of numerical magnitude that are grounded in a vertically organized mental number space.

Moving the eyes along the mental number line: Comparing SNARC effects with saccadic and manual responses
TLDR
Two experiments involving comparisons of saccadic and manual parity judgment tasks clearly support the first view; they also establish a vertical SNARC effect, suggesting that the magnitude representation resembles a number map, rather than a number line.

General Magnitude Representation in Human Infants
TLDR
It is shown that 9-month-olds transfer associative learning across magnitude dimensions, and this results provide support for the existence of an early-developing and prelinguistic general magnitude system, whereby representations of magnitude information are (at least partially) abstracted from the specific dimensions.
Eye position predicts what number you have in mind
The mental representation of parity and number magnitude.
Nine experiments of timed odd-even judgments examined how parity and number magnitude are accessed from Arabic and verbal numerals. With Arabic numerals, Ss used the rightmost digit to access a store…
Interactions between number and space in parietal cortex
TLDR
It is proposed that these numerical–spatial interactions arise from common parietal circuits for attention to external space and internal representations of numbers.
