Measuring individual differences in children's emerging language abilities is important to researchers and clinicians alike. The 2 most widely used methods for assessing children's vocabulary both have limitations: Experimenter-administered tests are time-consuming and expensive, and parent questionnaires have only been designed for children up to…

There is empirical evidence to suggest that oral language and vocabulary on entering kindergarten are the best predictors of later reading success. Identifying skills that are predictive of later achievement using psychometrically sound measurement methods is a necessary component of early intervention efforts. Currently, there are limited methods…

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…

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…

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)

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)
