Recent court actions have spurred psychologists to develop improved assessment tools and to utilize diagnostic measures that take into consideration developmental and affective growth patterns of disadvantaged and minority youth. The present study, working through a case vignette, has weighed the possibility that the FM index may serve as a forerunner of abstract thinking, or the capacity to internalize imagery, which, in Rorschach theory, is, with older subjects, best illustrated in M. Findings also suggest that the Z (Organizational Activity) index may not be useful in evaluating intellectual potentials of preschool minority children. Following blind analysis of the Rorschach, replicative data were obtained through a social history and an individually-administered ability test. Data from these sources support the major finding that FM may enable educational diagnosticians to estimate more accurately the intellectual capabilities of some preschool minority and other culturally disadvantaged children.The past decade has witnessed an increased emphasis on the need to assess more accurately the intellectual capabilities of children, and particularly minority children. There is general agreement that black youngsters secure, on most measures of intelligence, average attainments that fall approximately one standard deviation below those of whites. Reasons for this racial gap are unclear, and the implications obscured, because of considerable racial overlap. Yet, extensive and significant educational questions have arisen because of the (average) racial gap.
