The present study compared the effects of discrete trial instruction (DTI) and mand training on the acquisition of independent requests in 6 children with autism. Two multiple-probe designs across participants were conducted with 3 participants receiving mand training followed by DTI and the other 3 receiving DTI followed by mand training. Eye…

The Cognitive Levels Test (CLT) and the Peabody Picture Vocabulary Test-Revised (PPVT-R) were administered to 30 freshman college students at a small state college in the mid-Atlantic region. Significant correlations indicate that the PPVT-R measures a component of the CLT. Mean PPVT-R scores were significantly higher than CLT means. (Author/PB)

Examined the concurrent validity of the Peabody Picture Vocabulary Test-Revised (PPVT-R) and the Kaufman Assessment Battery for Childen (K-ABC) with 47 students referred for learning difficulties. Data analysis indicated that the K-ABC Achievement global scale was the only significant predictor of the PPVT-R. Implications for practitioners are…

The Wechsler Preschool and Primary Scale of Intelligence (WPPSI) has recently undergone a major revision and restandardization to update its 20-year-old norms, extend the age range down to age 3 and up to age 7 years, update and revise its test items, and increase its appeal to young children. This paper presents the results of a concurrent…

Explored the relationship between the Peabody Picture Vocabulary Test-Revised (PPVT-R) and the Peabody Individual Achievement Test (PIAT) administered to a sample of 29 mentally retarded children. Findings indicated that the PPVT-R predicted achievement as measured by the PIAT only moderately; and that PPVT-R scores correlated with achievement…

Examined the effectiveness of the Peabody Picture Vocabulary Test (Revised) as a screening instrument for gifted children. Although the PPVT-R may be useful as a screening measure with a general population, it offered little incremental effectiveness as a screening measure with a restricted range of ability.

The validity and reliability of the Peabody Picture Vocabulary Test was estimated with emotionally disturbed adolescents. Results indicated that the power of the test to predict future achievement of emotionally disturbed adolescents is comparable to that expected for normals. (Author)

The Peabody Picture Vocabulary Test Revised (PPVT-R) and the Comprehensive Tests of Basic Skills (CTBS) (reading, mathematics, and language subtests) were administered to 61 elementary school students in semi-rural Louisiana. Moderate positive correlations were found between PPVT-R scores and all CTBS subtests except mathematics computation. (GDC)

Adults (N=154) with developmental handicaps were tested on alternate forms of the Peabody Picture Vocabulary Test (PPVT) and the PPVT--Revised. A comparison of response profiles indicated a significant degree of correspondence in general performance using alternate forms. However, differences in consistency appeared when more specific comparisons…

The purpose of this study was to replicate and slightly refine and extend the procedures of Houston and Otto, who pointed out the need for studying the relationship between easily administered, individual measures of intelligence with more diagnostic and more highly validated measures. (Author/RK)

Administered the Peabody Picture Vocabulary Test-Revised, Peabody Picture Vocabulary Test, and Wechsler Adult Intelligence Scale-Revised to mildly retarded adults (N=21). Results indicated that the revised Peabody tended to yield significantly lower estimates of functioning than did the other measures. (Author/LLL)

While the PPVT is widely used with both typical (i.e., regular classroom students) and atypical (i.e., special class students such as retardates or cerebral palsied) children, there is a dearth of reliability data available for the typical group. (Authors)

The report provides detailed information about the methods and instruments used to evaluate school readiness initiatives, discusses important considerations in selecting instruments, and provides resources and recommendations that may be helpful to those who are designing and implementing school readiness evaluations. Study results indicate that…
