How Biased Are Culture-Loaded Tests?
Jensen, Arthur R.
The culture loaded Peabody Picture Vocabulary Test (PPVT) and the culture reduced Raven's Progressive Matrices (Colored and Standard forms) were examined and compared for large samples of white, black, and Chicano school children, K-8, in three California school districts. On both the PPVT and the Raven's the three ethnic groups show large mean differences but very little difference in the rank order of item difficulties, relative difficulty of adjacent items, the loadings of items on the first principal component, and the choice of distractors for incorrect responses. On both tests, groups of culturally homogeneous younger and older white children (separated by two years) perfectly simulated the white/Negro differences in Ethnic Group x Item interactions and choice of error distractors in the Raven's. Certain expectations from a culture bias hypothesis were borne out only for PPVT in the Mexican group. Unless the unlikely and empirically unsubstantiated assumption is made that culture bias affects all kinds of test items about equally, the various item analyses of the present studies lend no support to the proposition that either the PPVT or the Raven's is a culturally biased test for blacks.
