Cognitive bridge between geometric and numerical learning in monkeys.
Article in Proceedings of the National Academy of Sciences of the United States of America, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Educational research highlights strong developmental links between numerical and spatial cognition in humans, often shaped by cultural tools like the number line. However, emerging evidence suggests that these number-space connections may reflect our evolutionary history and emerge even in the absence of cultural tools. We examined how task-naïve monkeys learn spatial and numerical concepts over time. Monkeys' learning trajectories revealed successful learning of both numerical and geometric concepts. Discriminability effects showed that abstract quantitative features were stronger predictors of accuracy on both tasks than low-level visual similarity, reflecting abstract processing of both tasks. Cross-lagged analyses revealed that learning in the geometry task significantly predicted future gains in numerosity performance, even after controlling session-level trends, within-task stability, and general performance factors. Together, these findings provide evidence that spatial and numerical learning in primates rely on mutual cognitive processes. Such representations could form the evolutionary foundation for the well-documented "cognitive bridge" between numerical and spatial reasoning in human development.
