Performance on Piagetian tasks of Black children of differing socioeconomic levels.

233 Black children in Grades 1–6 and from 2 socioeconomic (SES) levels, as determined by eligibility for the school lunch program and parents' occupations, were given 5 Piagetian tasks to determine if differences in SES were associated with differences in cognitive development levels. Measures of reasoning, seriation, classification, causation, and conservation were used. Analysis of variance (ANOVA) showed that in all 5 variables the higher SES Ss performed better than lower SES Ss. The conservation measure showed distinct developmental differences between the high- and low-SES Ss. Examination of the means suggested only a small difference in developmental level between the SES groups on the other tasks. (21 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
