Children between the ages 8–17 years were recruited for an ongoing multisite research study conducted by CIFASD. Details about the CIFASD clinical projects have been described elsewhere (Mattson et al., 2010a). Children included in this study comprised 3 groups: those with heavy prenatal alcohol exposure (the AE group), non-exposed children with a diagnosis of ADHD (the ADHD group), and typically developing non-exposed control children (the CON group).
