“…FASD affects 0.3 to 10 individuals per 1000 live births (May and Gossage, 2001), and is the leading cause of preventable mental retardation (Abel and Sokol, 1986). Children with FASD show widespread structural brain abnormalities (Archibald et al, 2001;Fryer et al, 2009;Lebel et al, 2008;Mattson et al, 1996), and may have various cognitive and behavioral impairments including motor delays, and deficits of attention, executive functioning, language, learning, and memory (Jacobson and Jacobson, 2002;Kalberg et al, 2006;Mukherjee et al, 2006;Spadoni et al, 2007). Despite an array of intellectual impairments, individuals with FASD generally have greater difficulty with arithmetic than other cognitive domains (Howell et al, 2006;Kopera-Frye et al, 1996;Rasmussen and Bisanz, 2009) and mathematical ability is more strongly correlated with amount of prenatal alcohol exposure than are other academic skills (Goldschmidt et al, 1996;Streissguth et al, 1994).…”
