Abstract
This study was designed to investigate the relatively poor performance of lower class children on tests of auditory discrimination. Each of 30 middle class and 15 lower class kindergarten children was individually administered two tests of auditory discrimination. One of the tests was the Wepman, and the other was similar to the Wepman except that phonemes were exchanged between word pairs to create nonsense syllables. Error scores were analyzed, and it was shown that social class differences in error scores disappeared with the use of the distorted form of the Wepman. The results seem to suggest that the Wepman may measure a vocabulary factor in addition to auditory discrimination.
