Validity of the Peabody Picture Vocabulary Test as a measure of hearing vocabulary in mentally retarded and normal children.
The Peabody Picture Vocabulary Test (PPVT) and the auditory and visual subtests of the Illinois Test of Psycholinguistic Abilities (ITPA) were administered to 48 normal and 48 retarded subjects. Results suggested that the PPVT is not an adequate measure of hearing vocabulary for mentally retarded subjects. Half of each group was given the visual reception subtest of the ITPA in a form which had been modified to control the visual memory variable. No differences were found as a function of that variable. It was concluded that caution should be exercised when using the PPVT as a clinical diagnostic procedure in the assessment of receptive auditory vocabulary.
