Abstract	The two-factor theory proposed concerns familial mental retardation, in which retardation is mild (IQ 50-70) and persons appear clinically normal with no signs of neurological damage. It is stated that persons in this IQ range differ greatly in vocational, social, and other non-scholastic abilities, and that these differences are only slightly related to IQs obtained by standardized tests. Children of low SES status are seen to show the greatest discrepancy between non-academic abilities and their low IQs. Two broad types of mental ability are delineated: Level I, the non-academic skills (non-transformational learning and retention), and Level II, the academic (intelligence, i.e., analytic understanding, reasoning, abstraction, conceptual thinking). Level II includes the processes generally measured by intelligence tests. Retarded low SES children are found to be superior in Level I ability to middle SES children of similar IQ. Level I and II abilities in the general population are analyzed, as are the nature of the relationship between the Levels, and the physiological basis of Level I and II abilities. (KW)
