The Peabody Picture Vocabulary Test, Stanford-Binet, and the Modified Stanford-Binet with Normal and Cerebral Palsied Preschool Children
1This paper was supported, in part, by Department of Health, Education, and Welfare, Social and Rehabilitation Service Grant 15-P-55277/9-02, "Intelligence Test Modifications on Handicapped and Nonhandicapped Children." It is partly based on an unpublished master’s thesis completed at San Diego State College by the second author. The present investigation was designed to determine the validity of two pointing tests of intelligence-the Peabody Picture Vocabulary Test (PPVT) and the Stanford-Binet Intelligence Scale Modified (SB Modified)-by comparing them with the standard Stanford-Binet Intelligence Scale (SB) in normal and cerebral palsied populations. The PPVT has been generally recommended as being useful whenever a quick screening device is needed (Burnett, 1965; Hammill & Irwin, 1965; Hughes & Lessler, 1965; Tempero & Ivanoff, 1965). However, this recommendation does not hold for testing ethnic minority-group preschool children because the PPVT yields 10s that
