“…Although deficient PA is typically associated not with ADHD but rather with RD (Boada et al, 2012; Kroese, Hynd, Knight, Hiemenz, & Hall, 2000; McGrath et al, 2011; Purvis & Tannock, 2000; Willcutt et al, 2005; Willcutt, Pennington, Olson, & Defries, 2007), there are occasional reports of poor PA performance of ADHD groups (e.g., Kroese et al, 2000), especially if the PA task employed is relatively time-consuming or imposes a relatively high level of working memory (WM) load.
