All available 16-year-olds in a midwestern community were given the Stanford-Binet, Wechsler-Bellevue (Performance Scale), Iowa Silent Reading, Minnesota Paper Form Board, Minnesota Mechanical Assembly, and Chicago Assembly Test for Girls. Following the procedure of the social status method, the subjects were placed on a scale of social classes. Intercorrelations of test results were calculated, and the means of various groups compared. No significant differences between social classes were found for Mechanical Assembly Test scores, but in all other tests subjects from families of higher social status tended to score higher than those of lower social position. No significant sex differences were obtained. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
