Abstract
This study explored the feasibility of discriminating among subtypes of mental retardation on the basis of observable behavior. The major focus was on discrimination between Ss whose low I.Q. could be attributed to normal chromosomal or single locus genetic defects. Concurrently the study sought t o distinguish among diagnostic subgroups of the second category. Three groups of institutionalized subjects were used: Undifferentiated (presumed polygenic segregants), PKU, and Down's Syndrome.Keywords
