The recent study by Willams and colleagues utilized a novel robotic virtual reality measurement system to measure sensory-motor processing deficits in children with fetal alcohol spectrum disorders (FASDs). This system and the precise quantitation of distinct constituent behavioral processes may hold considerable utility and importance for the study of FASD-related motor deficits, their neural bases, and translational research efforts using homologous behavioral approaches in animal and human studies..
