    "title": "A 6-month longitudinal study on numerical estimation in preschoolers",
    "subtitle": null,
    "abstract": "The current study investigated the development of numerical\nestimation in 3- to 5-year-old children sampled monthly for six\nmonths. At each session, children completed a task that\nassesses verbal number knowledge (Give-N task) and a\nnumerical estimation task that assesses approximate number\nknowledge (Fast Cards). Results showed that children who\nacquired the cardinal principle (CP) during the course of the\nstudy showed marked improvement on the estimation task.\nFollowing CP acquisition, estimation became more accurate\noverall but also fluctuated widely. We discuss the implications\nof our findings for number word learning, particularly the\nmapping between verbal number and the approximate number\nsystem (ANS).",
