A Two-Minute Paper And Pencil Test Of Symbolic And Nonsymbolic Numerical Magnitude Processing Explains Variability In Primary School Children’S Arithmetic Competence, Nadia Nosworthy, Stephanie Bugden, Lisa Archibald, Barrie Evans, Daniel Ansari

Faculty Publications

Recently, there has been a growing emphasis on basic number processing competencies (such as the ability to judge which of two numbers is larger) and their role in predicting individual differences in school-relevant math achievement. Children’s ability to compare both symbolic (e.g. Arabic numerals) and nonsymbolic (e.g. dot arrays) magnitudes has been found to correlate with their math achievement. The available evidence, however, has focused on computerized paradigms, which may not always be suitable for universal, quick application in the classroom. Furthermore, it is currently unclear whether both symbolic and nonsymbolic magnitude comparison are related to children’s performance on tests …
