{"pk":26326,"title":"The Relationship Between the Numerical Distance Effect and Approximate Number\nSystem Acuity is Non-Linear","subtitle":null,"abstract":"People can estimate numerical quantities, like the number of\ngrapes in a bunch, using the Approximate Number System\n(ANS). Individual differences in this ability (ANS acuity) are\nemerging as an important predictor in research areas ranging\nfrom math skills to judgment and decision making. One\ncommonly used ANS acuity metric is the size of the\nNumerical Distance Effect (NDE): the amount of savings in\nRT or errors when distinguishing stimuli values as the\nnumerical distance between them increases. However, the\nvalidity of this metric has recently been questioned. Here, we\nmodel the relationship between the NDE-size and ANS\nacuity. We demonstrate that the relationship between NDE-\nsize and ANS acuity should not be linear, but rather should\nresemble an inverted J-shaped distribution, with the largest\nNDE-sizes typically being found for near average ANS\nacuities.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Numerical Distance effect; Estimation;\nApproximate Number system"}],"section":"Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/22t369xh","frozenauthors":[{"first_name":"Dana","middle_name":"","last_name":"Chesney","name_suffix":"","institution":"St. John’s University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2016-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/26326/galley/15962/download/"}]}
