The field dependence-independence of normally developing and mentally retarded boys of low and upper/middle socioeconomic status was examined. To test the cognitive style, the 96 young participants were subdivided into four groups (n=24 per group) matched on mean mental age, using the Raven Colored Progressive Matrices. Two groups of mentally retarded boys (Groups A and B) and two groups of normally developing boys (Groups C and D). Groups A and C were matched on mental age at 5.6 yr.; Groups B and D were matched on mental age at 7.6 yr. Each pair of groups differed significantly in mean chronological age. Within each subgroup, 12 boys came from upper/middle socioeconomic status families and 12 from low socioeconomic status families. Analysis indicated absence of significant differences between Groups A and C on field dependence-independence, but there were statistically significant differences between Groups B and D. Moreover, analysis showed that boys from families of upper/middle socioeconomic status, both normally developing and mentally retarded, were consistently more field independent than boys from families of low socioeconomic status. Finally, conclusions were drawn concerning the empirical and theoretical benefits for psychology and education, which arise from the study of field dependence-independence of mentally retarded individuals.
