Abstract
This paper proposes an investigation designed to compare the Wechsler Intelligence Scale for Children- Revised (WISC-R) and the Peabody Picture Vocabulary Test- Revised (PPVT-R). The historical development of intelligence testing and emergence of theories of intelligence are discussed. The Wechsler instruments, and the Peabody Picture Vocabulary Test (PPVT). Validation research relevant to the WISC-R and PPVT-R are reviewed. Based on the relative lack of studies designed to establish the concurrent validity of the PPVT-R, four hypotheses are proposed concerning the relationship of this new instrument to the WISC-R. These hypotheses are: 1) the Full Scale IQ (FS IQ) of the WISC-R will differ significantly from the standard scores of the PPVT-R; 2) the correlational relationship between the standard scores of the PPVT-R and the three WISC-R IQ scores will adhere to an order of Verbal Scale IQ vs (IQ) > FS IQ > Performance Scale IQ (PS IQ); 3) the standard scores of the alternate forms of the PPVT-R will not differ significantly from one another; and 4) the order of administration of the PPVT-R and WISC-R will not affect the scores of either instrument. Forty regular classroom second grade students will serve as subjects for this study. The hypotheses will be evaluated through the use of Pearson product-moment correlations, regression lines, standard errors of estimate scores, correlate t tests, and analysis of variance statistical procedures. The results will be discussed in relation to previous research and the appropriateness of using the PPVT-R as a screening instrument.
