Impulsive versus inefficient problem solving in retarded and nonretarded Mexican children.

Nonretarded (n = 12) and retarded (n = 12) Mexican children matched on chronological age were given the Matching Familiar Figures Test (MFFT). The results indicated that the MFFT was appropriate for use with Mexican retarded and nonretarded subjects. Comparisons between groups showed retarded performers to be less efficient information processors than nonretarded subjects. The two groups did not differ in cognitive style. Cross cultural comparisons of MFFT scores with normative data on American children were described within the constraints of the restrictive characteristics of the Mexican sample.
