Research in healthy adults has shown that numerosity, duration, and space share a partly common system of magnitude processing and representation. However, in DD, numerosity processing has until now received much more attention than the processing of other non-numerical magnitudes. To assess whether or not the processing of non-numerical magnitudes is impaired in DD, the performance of 15 adults with DD and 15 control participants was compared in four categorization tasks using numerosities, lengths, durations, and faces (as non-magnitude-based control stimuli). Results showed that adults with DD were impaired in processing numerosity and duration, while their performance in length and face categorization did not differ from controls\u2019 performance. Our findings support the idea of a nonsymbolic magnitude deficit in DD, affecting numerosity and duration processing but not length processing.<\/jats:p>","DOI":"10.1177\/0022219417732338","type":"journal-article","created":{"date-parts":[[2017,9,23]],"date-time":"2017-09-23T04:45:18Z","timestamp":1506141918000},"page":"600-611","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":23,"title":["Developmental Dyscalculia in Adults: Beyond Numerical Magnitude Impairment"],"prefix":"10.1177","volume":"51","author":[{"given":"Alice","family":"De Visscher","sequence":"first","affiliation":[{"name":"Universit\u00e9 catholique de Louvain, Louvain-la-Neuve, Belgium"},{"name":"KU Leuven, Leuven, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marie-Pascale","family":"No\u00ebl","sequence":"additional","affiliation":[{"name":"Universit\u00e9 catholique de Louvain, Louvain-la-Neuve, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mauro","family":"Pesenti","sequence":"additional","affiliation":[{"name":"Universit\u00e9 catholique de Louvain, Louvain-la-Neuve, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Val\u00e9rie","family":"Dormal","sequence":"additional","affiliation":[{"name":"Universit\u00e9 catholique de Louvain, Louvain-la-Neuve, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2017,9,23]]},"reference":[{"key":"bibr1-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890425596"},{"key":"bibr2-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1016\/S1364-6613(02)02040-5"},{"key":"bibr3-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuropsychologia.2010.05.028"},{"key":"bibr4-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1080\/09297049.2014.922170"},{"key":"bibr5-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1201\/9780203009574.ch6"},{"key":"bibr6-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1037\/0097-7403.24.1.84"},{"key":"bibr7-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1098\/rstb.2009.0028"},{"key":"bibr8-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-7610.2005.00374.x"},{"key":"bibr9-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1016\/j.tics.2010.09.007"},{"key":"bibr10-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1162\/jocn_a_00546"},{"key":"bibr11-0022219417732338","doi-asserted-by":"publisher","DOI":"10.3389\/fpsyg.2011.00364"},{"key":"bibr12-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuropsychologia.2009.05.024"},{"key":"bibr13-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuropsychologia.2011.07.014"},{"key":"bibr14-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1016\/j.pneurobio.2007.11.001"},{"key":"bibr15-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1017\/S0140525X09990938"},{"key":"bibr16-0022219417732338","doi-asserted-by":"publisher","DOI":"10.3389\/fpsyg.2014.00004"},{"key":"bibr17-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuron.2007.10.004"},{"key":"bibr18-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1323628111"},{"key":"bibr19-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1016\/j.jecp.2010.09.003"},{"key":"bibr20-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1016\/j.tine.2013.06.001"},{"key":"bibr21-0022219417732338","volume-title":"TTR Tempo-Test-Rekenen","author":"De Vos T","year":"1992"},{"key":"bibr22-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1016\/j.cortex.2007.08.011"},{"key":"bibr23-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1002\/hbm.21300"},{"key":"bibr24-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuropsychologia.2012.06.006"},{"key":"bibr25-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1002\/hbm.20677"},{"key":"bibr26-0022219417732338","first-page":"107","volume-title":"Horizons in Neuroscience Research","volume":"8","author":"Dormal V.","year":"2012"},{"key":"bibr27-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1016\/j.actpsy.2005.06.003"},{"key":"bibr28-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1016\/S1364-6613(99)01424-2"},{"key":"bibr29-0022219417732338","doi-asserted-by":"publisher","DOI":"10.1037\/a0026218"},{"key":"bibr30-0022219417732338","doi-asserted-by":"crossref","unstructured":"Gilaie-Dotan S., Rees G., Butterworth B., Cappelletti M.
