Social-Class Differences on the Mc Carthy Scales for Black and White Children

Abstract

The relationship of social class to the cognitive and motor Indexes yielded by the McCarthy scales was explored for representative groups of black (n = 154) and white (n = 862) children aged 2½ to 8½ yr. For both racial groups, children categorized as middle class scored significantly higher than working-class youngsters on each of the six indexes. The pattern of mean Indexes for different occupational groups resembled the pattern of mean IQs found in previous studies.
