Tasks tapping more basic cerebellar functions also have been able to discriminate children with FASD and ADHD. In one study, children with FASD failed to learn a classically conditioned eyeblink response, producing longer latencies and poorly timed responses to the conditioning stimulus. Children with ADHD, on the other hand, were impaired on measures of adaptively timed responses but showed learning of the conditioned eyeblink response that was similar to controls (Coffin, et al., 2005). In other studies of motor abilities, children with ADHD were more likely to be clinically impaired on measures of postural stability than were children with FASD (Kooistra, et al., 2009).
