Demographic data for the study groups are listed in Table 2. These data were analyzed using Fisher’s exact test or Chi-square test for categorical data and ANOVA for continuous data. An alpha level of p < .05 was used to determine statistical significance. Alpha levels of p = .05–.08 were considered to be marginally significant. The AE/FAS group differed from the CON group on race, ethnicity, country of origin (U.S. vs. South Africa), and, as expected, on growth variables, microcephaly, measures of structural abnormality, presence of an ADHD diagnosis, and FSIQ. They were marginally different on handedness (Fisher’s exact p = .072). They did not differ on sex or age. The AE/Non-FAS group differed from the CON group on race, growth variables, microcephaly, measures of structural abnormality, presence of an ADHD diagnosis, and FSIQ. They were marginally different on handedness (Fisher’s exact p = .050). The two groups did not differ on sex, ethnicity, country of origin, or age. The combined AE group differed from the ADHD group on age, sex, race, ethnicity, country of origin, growth variables, microcephaly, measures
