This paper outlines some practical implications of new work on the behavioral effects of genetic mental retardation disorders. After describing historical and definitional issues concerning so-called "behavioralphenotypes," we use Down syndrome and Williams syndrome to illustrate how specific genetic disorders might differentially predispose individuals to particular, etiology-related behaviors. We then explore educational and other intervention implications of such etiology-related behaviors, before ending with a discussion of the area's critical unresolved issues.
