Impaired acuity of the approximate number system underlies mathematical learning disability (dyscalculia) |pdf=|usr=}}{{21679173}} gab.com Text Impaired acuity of the approximate number system underlies mathematical learning disability (dyscalculia) JO: Child Dev http://www.kidney.de/pget.php?&tw=1&pmid=21679173 #FOAvip Many children have significant mathematical learning disabilities (MLD, or dyscalculia) despite adequate schooling. We hypothesize that MLD partly results from a deficiency in the Approximate Number System (ANS) that supports nonverbal numerical representations across species and throughout development. Here we show that ninth grade students with MLD have significantly poorer ANS precision than students in all other mathematics achievement groups (low-, typically-, and high-achieving), as measured by psychophysical assessments of ANS acuity (w) and of the mappings between ANS representations and number words (cv). This relationship persists even when controlling for domain-general abilities. Furthermore, this ANS precision does not differentiate low- from typically-achieving students, suggesting an ANS deficit that is specific to MLD.
