When conducting classroom observations, researchers are often confronted with the decision of whether to conduct observations live or by using pre-recorded video. The present study focuses on comparing and contrasting observations of live and video administrations of the Classroom Assessment Scoring System-PreK (CLASS-PreK). Associations between…

Oral language skills are important to consider in school psychology practice, as they are directly tied to many areas of academic functioning. For example, research has demonstrated that oral language skills in early elementary school predict reading comprehension in later grades (Kendeou, van den Broek, White, & Lynch, 2009). With a…

This study presents an independent replication and extension of psychometric evidence supporting the "Theory of Mind Inventory" ("ToMI"). Parents of 20 children with ASD (4; 1-6; 7 years; months) and 20 with typical development (3; 1-6; 5), rated their child's theory of mind abilities in everyday situations. Other parent report…

In a response-to-intervention framework, schools typically employ a direct route approach to screening, in which students identified as at risk by a screening process are directly placed into intervention. Direct route approaches require screening decisions to be highly accurate, but few studies examining the predictive validity of reading…

The present study examined the psychometric properties of scores from a direct measure of behavioral regulation, the Head-Toes-Knees-Shoulders task (HTKS) with 3- to 6-year-old children in the United States, Taiwan, South Korea, and China. Specifically, we investigated (a) the nature and variability of HTKS scores, including relations to…

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…

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…

Seeks to determine convergent validity values and to compare intelligence estimates for three tests across various levels and ranges of intelligence. Results indicated that the use of the PPUT or DAP for determining intelligence of kindergarten children is unjustified. (Author/PC)

Reviews a recent paper by Levy (1982) which concluded that a new format of the Peabody Picture Vocabulary Test was valid for autistic children. Claims the analysis was inappropriate and presents a statistical test to compare differences between independent mean differences. Includes a reply by Stine Levy. (Author/JAC)

This study compared the WISC-R and PPVT scores for a group of 65 students classified as mentally retarded, ranging in age from 7.5 to 14.5. For this sample of mildly retarded children and youth, the PPVT IQ score is significantly higher than the Full Scale IQ from the WISC-R. (Author)

The mean IQ on the Slosson Intelligence Test (SIT) was substantially higher than expected based on the earlier Peabody Picture Vocabulary Test (PPVT) scores. Sampling error and examiner error were excluded as explanations. Results suggest that the PPVT and SIT yield different scores and lack comparability. (Author)

Scores of 66 elementary students (referred for poor learning progress) on the Peabody Picture Vocabulary Test-Revised (PPVT-R) were below mean performance on all Stanford-Binet Intelligence Scale-Fourth Edition (SB:FE) area scores except memory. The study refutes the assertion that the PPVT-R is an appropriate screening instrument for the SB:FE.…

AN INVESTIGATION OF THE VALIDITY OF INTELLIGENCE AND OTHER TESTS USED IN THE DIAGNOSIS OF RETARDED CHILDREN WAS PERFORMED. EXPERIMENTAL SAMPLES CONSISTED OF 101 CHILDREN SELECTED FROM SPECIAL CLASSES FOR EDUCABLE MENTALLY RETARDED (EMR) WHOSE AGES RANGED FROM 6.9 TO 10 YEARS AND WHOSE IQ SCORES RANGED FROM 50 TO 80. THE TESTS EVALUATED WERE (1)…

Results show that Peabody Picture Vocabulary Test (PPVT) IQs are not interchangeable with Wechsler Intelligence Scale for Children-Revised (WISC-R) IQs in a sample of reading disabled children. The PPVT yielded higher IQs on the average than did the WISC-R, supporting results obtained with learning disabled students. (Author/BEF)
