    "title": "Beyond Magnitude:\nHow Math Expertise Guides Number Representation",
    "subtitle": null,
    "abstract": "Previous studies on numeric cognition have focused primarily\non magnitude, based on its role as a core feature of number\nknowledge. In this paper, we report the results of three\nexperiments investigating adults’ sensitivity to properties of\nnumber apart from magnitude. In Experiment 1, we use a\ntriadic judgment task to replicate a classic study of number\nproperties. In Experiment 2, we compare these representations\namong expert and non-expert groups. In Experiment 3, we\nexamine whether instruction can tune representation of\nnumber properties. Results indicate that the triadic\ncomparison task is a reliable method of assessing sensitivity\nto number properties. We found that magnitude is difficult to\nsuppress among non-experts, who are primarily attuned to\nmagnitude and parity. Mathematically sophisticated\nparticipants were sensitive to a range of number properties\ncompared with the non-expert group. We discuss implications\nfor theories of number concepts and their relation to special\npopulations",
