Renzi and Vignolo Token test: what it is and how is it used in psychology

Language is a tool that allows us to communicate, to express our desires and opinions, as well as to describe reality. That is why its assessment is of vital importance, especially in childhood and in cases where it can be changed.

here we will know the Test Token of Renzi and Vignolo, A test that assesses a very specific but fundamental function, verbal comprehension or receptive language. In addition, it also allows other cognitive aspects to be evaluated, as we will see later.

    Renzi and Vignolo token test: features

    The test token was developed by Ennio De Renzi and Luigi Vignolo in 1962. In 1979 it was adapted and standardized. On the other hand, De Renzi and Faglioni produced a brief version in 1978 of 36 articles.

    This is a test widely used in clinical practice and research to explore the verbal comprehension of orders of increasing complexity. This is due to its ease of administration, application, correction and analysis, and its high sensitivity to detect language difficulties in various pathologies. In addition, its design is quite simple. It applies to ages between 6 years and 11 years and 11 months.

    Initially, in 1962, the test token was introduced in Italian by De Renzi and Vignolo as an instrument that detects slight alterations in receptivity to aphasic language.

    structure

    The Test De Renzi i Vignolo token consists of 20 tokens or tokens of five colors (red, blue, green, yellow, white), two shapes (circles, squares) and two sizes (large, boys), which they are manipulated by the subject according to the verbal orders of the examiner. The examiner will read each command as the subject attempts to complete it.

    They are organized in 5 sections of instructions, arranged in an increasing degree of complexity according to the number of operations required to solve the task. In total there are 62 commands / instructions.

    Functions it evaluates

    Its progressive application makes it possible to determine, from the subject’s responses, the presence or absence of certain cognitive functions, but fundamentally assess receptive language (comprehension). It can also detect the presence of any functional or organic pathology (always according to the experience and knowledge of the assessor).

    On the other hand, the Renzi and Vignolo test token can be useful to assess aspects of other cognitive domains such as the integrity of working memory or other functions such as immediate memory, short term memory. and remote memory. stability and others.

    The basic feature of Renzi and Vignolo’s Token test is that understanding each word of the verbal order is essential to accomplish the task. In other words, the progress is not repetitive, because each instruction must be decoded correctly to execute it.

      application

      When applying the test, the subject being examined should not fix his or her eyes on the lips of the examiner. However, before taking the test, the examiner should determine if the person knows the colors to be used as well as the shapes.

      The examiner should explain to the subject that they will be asking them to perform different activities with the worksheets. In addition, you will need to listen carefully as you will be asked to do each activity only once. Finally, it will ask you if you are ready to start.

      As we have seen, the test consists of 5 parts; if the candidate makes 8 errors in the first part, the test is suspended. Otherwise, all 5 parts are administered. All items are given a correct (+) or incorrect (-) score.

      Equipment

      The material that makes up the Test De Renzi i Vignolo token is: the application and interpretation manual, a set of 20 wooden worksheets, a workbook, a block of protocols, sets of response and stimuli letters and annotation sheets.

      Uses in clinical and educational practice

      The Renzi and Vignolo test token can be used as a general orientation test, but also, and depending on the experience of the examiner, as a complementary use with other more specific and in-depth tests of language functions, as well as for ‘other objectives (if the examiner has sufficient experience).
