    "abstract": "Mathematical expertise builds on a foundation of space,\nespecially the ability to map exact numbers to linear space.\nThis “mental number-line” is known to vary cross-culturally,\nbut there is debate about the mechanisms responsible for its\ncultural elaboration. We investigated the role of co-speech\ngesture, a ubiquitous cultural activity, in stabilizing and\nentrenching the mental number-line within a community.\nImitating culture-specific gestures systematically shaped\ngesturers’ mental number-line. Moreover, gestures were used\nspontaneously to infer speakers’ spatial understanding of\nnumber, and merely observing these gestures was sufficient to\nshape the observer’s own mental number-line. These findings\nestablish co-speech gesture as one mechanism for propagating\nand perpetuating the number-line",
