> Research on ADHD has particularly emphasized impairments in inhibitory control (Barkley, 1997; Nigg, 2000) and working memory (Castellanos & Tannock, 2002; Martinussen, Hayden, Hogg-Johnson, & Tannock, 2005). Barkley’s (1997) model of ADHD emphasizes inhibitory control (i.e. inhibition of prepotent response, stopping an ongoing response, and interference control) as the primary neuropsychological impairment, which underlies secondary impairments in working memory and related functions
