The Peabody Picture Vocabulary Test (PPVT) was designed as a test of receptive vocabulary achievement and verbal ability. Subjects were shown four numbered pictures and were read a word by a research assistant. The subject was then asked to point to the picture or say the number of the picture that corresponded to the word spoken by the research assistant.
WAVE 3: The Peabody Picture Vocabulary Test (PDF 3.4MG) was administered to subjects in Cohort 0.
