Developmental aspects of linguistic and mnestic abilities in normal children.
The Peabody Picture Vocabulary Test-Revised (PPVT-R), Boston Naming Test (BNT), Paired Associate Learning of the Wechsler Memory Scale (PAL), and verbal fluency tests were administered to 241 normal children aged 6-12 years. Normative data were compiled for the BNT, PAL, and verbal fluency tests. A Principal Components Factor Analysis with Varimax Rotation was conducted to determine whether the tests evaluated similar or differential functions. Three factors emerged, accounting for 67.7% of the variance: Factor 1 contained loadings from two semantic fluency measures (animals and food), Factor 2 contained the PPVT-R and the BNT, and Factor 3 contained two measures from the PAL (easy and hard associations). In children, the BNT relates more to word knowledge than to retrieval or fluency, and verbal memory appears to be relatively independent of these linguistic functions.
