Peabody Picture Vocabulary Test: Uses and Characteristics

A psychological test used to assess the verbal aptitude and vocabulary of children and adults.

The evaluation of vocabulary in childhood, both receptive and expressive, is of vital importance in those cases where it or they appear altered or where there is some other disorder (e.g. a neurodevelopmental disorder).

Here we will learn about a useful tool to assess receptive language in almost all ages: the Peabody Picture Vocabulary Test.. We will learn about its characteristics, what it is used for and how it is applied.

The Peabody Picture Vocabulary Test: Characteristics

The Peabody Picture Vocabulary Test (PPVT-III) was developed by Ll. M. Dunn and L.M. Dunn in 1997. In 2006 D. Arribas elaborated the Spanish adaptation (TEA Ediciones). The PPVT-III is an adaptation of the Peabody Picture Vovabulary Test-Revised, although it differs from it in that it does not establish any correlation with IQ.

It is a test to detect a test to detect language difficulties and to assess verbal aptitude and vocabulary.. It evaluates listening comprehension or verbal comprehension.

It is of individual application, and the application time is between 10 and 20 minutes, although it is usually 11 to 12 minutes. The age of application is from 2 and a half years old to 90 years old.

The material required for the application of the Peabody Picture Vocabulary Test are the manual, 25 note sheets and the visual stimuli booklet..

Structure

The Peabody Picture Vocabulary Test consists of 192 sheets preceded by 5 practice items. Each sheet has 4 simple black and white illustrations.The test questions are organized in the form of a multiple-choice test. The task of the examinee will be to select the image that represents the best meaning of the word presented verbally by the examiner (e.g. "pear").

Item sets that are too easy or too difficult are not applied to the subject; therefore, subjects generally respond to a total of 7 sets.

The correction of the test is generally fast and objective.and is carried out simultaneously with the application of the test.

Purposes

The basic purposes of the Peabody Picture Vocabulary Test are as follows.

1. To evaluate the level of receptive vocabulary

Receptive vocabulary, also called passive vocabulary or reception vocabulary, is the vocabulary that a speaker is able to interpret in different situations of message reception. Consequently, receptive vocabulary is part of a speaker's mental lexicon..

In this sense, it is a performance test that measures the level of vocabulary acquisition of a subject. It should be understood as a test of achievementIt is a test of vocabulary acquisition in Spanish.

2. Rapid detection of difficulties or screening of verbal aptitude.

The Peabody Picture Vocabulary Test can be included as one more piece of data within a comprehensive battery of tests that evaluate different cognitive processes.. However, it can only be used in this sense when the habitual language at home, in the community or school of the examinee is Spanish.

Uses

The test is mainly applied in two contexts: clinical and school. It can be used children with reading difficulties or who have language problems; also in people with autism, autism, or autism.It can also be used with people with autism, psychosis, intellectual disability and withdrawal.

As we have seen, it can be used as a test to discern scholastic aptitude (verbal ability or intelligence) or as part of a cognitive battery.

Importance of vocabulary

A vocabulary test is believed to be the best single index of school or academic success. On the one hand, language is the main instrument for manipulating the more complex processes of thought, education and communication.On the other hand, a wealth of auditory vocabulary can be understood as an important measure of intellectual competence or ability.

Cautions

We should keep in mind that the Peabody Picture Vocabulary Test does not provide a global measure of intelligence, and that we should not make too many generalizations based on an instrument that only measures auditory vocabulary, mainly, since this is only one aspect of a person's complex linguistic and cognitive domain.

On the other hand, it is not recommended to apply the test to people with hearing difficulties or deafness..

Test construction

The construction of the test was based on the Item Response Theory, which ensures that only items appropriate to the aptitude level of the examinee are applied. Its Spanish adaptation had a representative sample of more than 2,500 subjects.
