Definition

The Peabody Picture Vocabulary Test, Fourth Edition (PPVT-4) is an interviewer-administered instrument that measures the receptive (hearing) vocabulary of the respondent. For each item, the examiner says a word and the respondent selects a picture that illustrates the word's meaning. The items sample words that represent 20 content areas (e.g., actions, vegetables, tools), and parts of speech (e.g., nouns, verbs). The Peabody Picture Vocabulary Test, Fourth Edition (PPVT-4) is a proprietary protocol and administration requires a licensing agreement from Pearson. Researchers should complete and return an application to pas.licensing@pearson.com. In order for this assessment to be considered valid, the investigator should make sure that the respondent speaks English as a first language and does not have a preexisting hearing impairment.
