Objective: Deficits in basic numerical skills, calculation, and working memory have been found in children with developmental dyscalculia (DD) as well as children with attention-deficit\/hyperactivity disorder (ADHD). This paper investigates cognitive profiles of children with DD and\/or ADHD symptoms (AS) in a double dissociation design to obtain a better understanding of the comorbidity of DD and ADHD. Method: Children with DD-only (N = 33), AS-only (N = 16), comorbid DD+AS (N = 20), and typically developing controls (TD, N = 40) were assessed on measures of basic numerical processing, calculation, working memory, processing speed, and neurocognitive measures of attention. Results: Children with DD (DD, DD+AS) showed deficits in all basic numerical skills, calculation, working memory, and sustained attention. Children with AS (AS, DD+AS) displayed more selective difficulties in dot enumeration, subtraction, verbal working memory, and processing speed. Also, they generally performed more poorly in neurocognitive measures of attention, especially alertness. Children with DD+AS mostly showed an additive combination of the deficits associated with DD-only and A_Sonly, except for subtraction tasks, in which they were less impaired than expected. Conclusions: DD and AS appear to be related to largely distinct patterns of cognitive deficits, which are present in combination in children with DD+AS.\u2029 <\/jats:p>","DOI":"10.1024\/1422-4917\/a000450","type":"journal-article","created":{"date-parts":[[2016,6,30]],"date-time":"2016-06-30T10:44:15Z","timestamp":1467283455000},"page":"365-375","source":"Crossref","is-referenced-by-count":35,"title":["Basic numerical processing, calculation, and working memory in                     children with dyscalculia and\/or ADHD symptoms"],"prefix":"10.1024","volume":"44","author":[{"given":"J\u00f6rg-Tobias","family":"Kuhn","sequence":"first","affiliation":[{"name":"Institute of Psychology, University of                     M\u00fcnster"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elena","family":"Ise","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent                     Psychiatry and Psychotherapy, Medical Faculty, University of Cologne"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Julia","family":"Raddatz","sequence":"additional","affiliation":[{"name":"Institute of Psychology, University of                     M\u00fcnster"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christin","family":"Schwenk","sequence":"additional","affiliation":[{"name":"Institute of Psychology, University of                     M\u00fcnster"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christian","family":"Dobel","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology,                     Friedrich-Schiller University Jena"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"101","reference":[{"key":"c1","doi-asserted-by":"publisher","DOI":"10.1177\/002221949703000605"},{"key":"c2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jecp.2006.10.001"},{"key":"c3","doi-asserted-by":"publisher","DOI":"10.1367\/A04-209R.1"},{"key":"c4","doi-asserted-by":"publisher","DOI":"10.1177\/108705479900300301"},{"key":"c5","first-page":"1","author":"Burr D.
