Non-symbolic numerosities do not automatically activate spatial–numerical associations: Evidence from the SNARC effect
Four experiments are reported that argue that non-symbolic representations of number do not offer a direct and automatic route to numerical–spatial associations and suggest that visual properties of non-Symbolic displays can prompt SNARC-like effects driven by visual cues rather than numerosity.
Making SNAP Judgments: Rethinking the Spatial Representation of Number
There was a significant interaction between pitch and number magnitude, analogous to the interaction between space and number: participants were faster to produce “high” pitches in response to “ high” numbers.

The SNARC is reexamine in Israelis who read text from right to left but numbers from left to right to show that a SNARC effect still emerges when the response dimension is spatially orthogonal to the conflicting processing dimension.
No horizontal numerical mapping in a culture with mixed-reading habits
The current results are congruent with the idea that text reading habits play an important role in the cultural differences observed in visuo-spatial tasks, but imply that these habits on their own are not strong enough to induce significant horizontal spatial-numerical associations.
Sequential Effects in SNARC
The results point to a strong inversion of number-space associations (left/large and right/small) when the last trial was incoherent - i.e. when a response with the left hand was made to a large number or vice-versa.
Spatial reference frames and SNARC
ABSTRACT In this work, the role that spatial reference frames play in determining the spatial-numerical association of response codes (SNARC) effect is examined. Participants were instructed to
It Does Exist! A Left-to-Right Spatial–Numerical Association of Response Codes (SNARC) Effect Among Native Hebrew Speakers
This work provides the first demonstration of a horizontal, left-to-right SNARC effect in native speakers of Hebrew performing the parity task, and succeeds in reducing the MARC effect by implementing the paritytask in 2 sessions, on 2 different days, each time using a different mapping of the parity- to-response side.
Automaticity of Access to Numerical Magnitude and Its Spatial Associations: The Role of Task and Number Representation
The results suggest that, while access to magnitude and its spatial associations is not automatic in an “all-or-none” sense, it is certainly at the strong end of automaticity, and that this automatic activation is modality dependent.
Spatial–Numerical and Ordinal Positional Associations Coexist in Parallel
The results question a pure working memory account for theSNARC effect and highlight the critical role of the number range employed in research about the SNARC effect, substantiating the view that both effects are not mutually exclusive but may co-exist.


Reading habits for both words and numbers contribute to the SNARC effect
This study compared the spatial representation of numbers in three groups of adults: Canadians, who read both English words and Arabic numbers from left to right; Palestinians, who read Arabic words
Shared spatial representations for numbers and space: the reversal of the SNARC and the Simon effects.
The authors observe an effect of an explicit spatially incompatible mapping rule on the way numerical information was associated with spatial responses and point to a shared spatial representation for explicit spatial information and implicit spatial information (numbers).
Linkages between Number Concepts, Spatial Thinking, and Directionality of Writing: The SNARC Effect and the REVERSE SNARC Effect in English and Arabic Monoliterates, Biliterates, and Illiterate Arabic Speakers
The current investigations coordinate math cognition and cultural approaches to numeric thinking to examine the linkages between numeric and spatial processes, and how these linkages are modified by
On the Cognitive Link between Space and Number: A Meta-Analysis of the SNARC Effect
Abstract An association of numbers and space (SNARC effect) has been examined in an ever growing literature. In the present quantitative meta-analysis, 46 studies with a total of 106 experiments and
Short Article: Coding Strategies in Number Space: Memory Requirements Influence Spatial–Numerical Associations
The findings are inconsistent with the idea that spatial–numerical associations are the result of an automatic and obligatory cognitive process but do suggest that coding strategies might be responsible for the cognitive link between numbers and space.

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
