The influence of semantics and numerical representation on the SNARC effect.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
World semantics refers to how individuals comprehend and ascribe meaning to phenomena within specific sociocultural and environmental contexts. And it significantly influences how people conceptualize numerical properties, such as quantity ("how many") and order ("which"), influencing their resolution of cardinal and ordinal numerical task. In order to reveal the influence of world semantics on the joint effects of encoding spatial-numerical responses related to cardinal and ordinal numbers, this study conducted three experimental contexts with distinct numerical representations: (1) a non-symbolic context, where numbers were represented using dot arrays; (2) a symbolic context, where numbers were presented as Chinese characters; and (3) a word problem solving context, where numerical values were embedded in real-world mathematical scenarios. To investigate how numerical attributes (cardinality vs. ordinality) influence on the SNARC effect under varying level of world semantics across these three contexts. Results showed that in the non-symbolic context, the SNARC effect is primarily observed for cardinal numbers. In the symbolic context, ordinal number elicited a stronger SNARC effect. However, in the word problem context, no significant SNARC effect was observed. The findings suggest that as world semantics become more prominent, the SNARC effect diminishes, particularly in applied numerical contexts. Additionally, ordinal numbers exhibited a stronger SNARC effect than cardinal numbers, supporting the role of sequential processing in spatial-numerical associations.
