The Peabody Picture Vocabulary Test-Revised (PPVT-R) and Slosson Intelligence Test (SIT) were designed, at least in part, to provide a quick estimate of scores which might be obtained on the Stanford-Binet Intelligence Scale, Form L -M, without requiring extensive technical training by the examiner. Both the PPVT-R and SIT are frequently used as screening instruments to identify children for possible placement in special education programs, remedial reading groups, speech and language therapy, gifted programs, or "tracks." This study investigated the value of the PPVT-R and SIT as screening instruments for the Fourth Edition Stanford-Binet.Fifty students, grades kindergarten through fifth, were randomly selected to participate in the study. All subjects were involved in regular education at least part-time. Subjects were administered the PPVT R, SIT, and Fourth Edition Binet by a single licensed school psychologist. The administration order of the instruments was randomized. Participants were tested on consecutive school days (10) until all subjects had been administered the three instruments.Correlation coefficients were determined for the Standard Score of the PPVT-R and each Standard Age Score of the Binet (four area scores and one total test score), as well as for the SIT IQ score and each Standard Age Score of the Binet. All correlations were positive and significant beyond the p<.Ol level except between the PPVT-R and Binet Quantitative Reasoning.Analyses of Variance were used to determine mean differences of scores obtained on the three instruments. Significant differences (p<.05) were found between scores on the PPVT-R and Abstract/Visual Reasoning, SIT and Verbal Reasoning, SIT and Short-Term Memory, SIT and Abstract/Visual Reasoning, and SIT and Total Test Composite.Results indicated that, in general, the SIT is a better predictor of Fourth Edition Binet scores than the PPVT R, however frequently yielded significantly different scores. It was concluded that neither the PPVT R nor SIT should be used as a substitute for more comprehensive measures of intellectual functioning, and caution should be used when interpreting their results. Much more research is needed to clarify the diagnostic value of the Fourth Edition Stanford-Binet as a psychometric instrument.

This study had three purposes: (1) to identify differential item functioning (DIF) on the PPVT-III (Forms A & B) using a partial correlation method, (2) to find a consistent pattern in items identified as underestimating ability in each ethnic minority group, and (3) to compare findings from an expert judgment method and a partial correlation method. Hispanic, African American, and white subjects for the study were provided by American Guidance Service (AGS) from the standardization sample of the PPVT-III; English language learners (ELL) of Mexican descent were recruited from school districts in Central and South Texas. Content raters were all self-selected volunteers, each had advanced degrees, a career in education, and no special expertise of ELL or ethnic minorities. Two groups of teachers participated as judges for this study. The "expert" group was selected because of their special knowledge of ELL students of Mexican descent. The control group was all regular education teachers with limited exposure to ELL. Using the partial correlation method, DIF was detected within each group comparison. In all cases except with the ELL on form A of the PPVT-III, there were no significant differences in numbers of items found to have significant positive correlations versus significant negative correlations. On form A, the ELL group comparison indicated more items with negative correlation than positive correlation [χ2 (1) = 5.538; p=.019]. Among the items flagged as underestimating ability of the ELL group, no consistent trend could be detected. Also, it was found that none of the expert judges could adequately predict those items that would underestimate ability for the ELL group, despite expertise. Discussion includes possible consequences of item placement and recommendations regarding further research and use of the PPVT-III.

The purpose of this study was to compare PPVT-R age equivalents with language ages from the Test of Early Language Development - TELD 2 (Hresko, Reid, and Hammill, 1981) for a preschool population. This study sought to find the strength of association between the PPVT-R age equivalents and the TELD language ages. The subjects used in the study were 54 preschool children ranging in age from 3-6 through 4-7 years. Normal children were selected for the study based on their chronological age, sex, and socioeconomic status - SES.

The algorithms for the mathematical modeling to predict productivity of underground room-and-pillar mining systems are well-known and documented. These algorithms consider the time-varying relationships between mining equipment for a given geometry of operations as well as other constraints. This study presents a newly developed, user-friendly visual simulation computer tool for the Windows environment. This tool can be easily customized and utilized by field engineers and will help mine operators plan the optimum mining sequence for different mine geometries and equipment layouts. Program output includes monitoring of shift data, equipment utilization indices, and so forth. The simulation technique can be used with any environment. Use of the system is demonstrated in different mining equipment configurations. Development and validation of the system was aided by the Peabody Group. / Master of Science

La version de langue française des items 40 à 79 de la forme A du test de vocabulaire "P.P.V.T.” a été validée par une procédure multi-technigues. Après une technique de retraduction réalisée par deux groupes de traducteurs, une autre équipe de traducteurs a analysé les différentes versions obtenues pour choisir la meilleure traduction à chacun des items. Deux groupes de sujets anglophone et francophone ont passé ce test ou sa version et, après analyse de leurs résultats, leurs moyennes se sont avérées être comparables. La version en langue française de cette partie du *’P . P . V .

The purpose of this study was to obtain data from the PPVT-R scores of low and middle SES black kindergartners in the Portland area to determine if there is a difference between their scores and the scores reported in the PPVT-R. The primary question to be answered was do the scores of black kindergartners in Portland vary significantly dependent upon SES? The secondary questions this study sought to answer were: what are the means, standard deviations, and ranges of scores for black kindergartners in Portland and what are the means, standard deviations, and ranges for each two-month age group of black kindergartners in Portland?

The purpose of this study was to determine the relationship between the Peabody Picture Vocabulary Test-Revised, (PPVT-R) and receptive subtest of the Preschool Language Scale (PLS), and between the PPVT-R and the Test of Auditory Comprehension of Language-Revised (TACL-R), as well as determine how the tests compare in identifying children in need of further evaluation in the area of receptive language. The reasoning behind the goal of this study was to determine that if the three tests showed a strong, positive correlation and identified the same children as needing further assessment, then perhaps the test which was easier and shorter to administer (the PPVT-R) could be used with more confidence 2 as a quick, reliable screening tool of overall receptive language ability. In other words, if a child does poorly on the PPVT-R, one could assume that the child would most likely score below average on the other two tests also. Based on the results of this study, one cannot make this assumption.
