1 · What the graph read from it

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.

2 · The registry

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

The spatial-numerical association of response codes (SNARC) effect refers to the phenomenon in which responses to small numbers are faster when the left hand is used, and responses to large numbers are faster when the right hand is used. Existing research has shown that cognitive load, such as memory load, is crucial in forming the SNARC effect, and the SNARC effect is smaller for math-skilled individuals than for those with low mathematical skills. However, the underlying mechanisms of how cognitive load and mathematical proficiency affect the SNARC effect remain unclear. This study employed a one-back number comparison task in which participants were asked to compare the current number with the N-1 number under a low or high cognitive load. The results showed that participants with low mathematical skills exhibited the SNARC effect under both cognitive loads. In contrast, participants with high mathematical skills showed the SNARC effect only under the high-load condition. These findings suggest that mathematical proficiency might be beneficial for individuals in resolving conflicts in the spatial-numerical association, but this advantage disappears under a high cognitive load.
