Tests of Raven - how to conduct and decipher?

Intellectual development of children is an important component of their adaptation in the society, the development of mental processes, interpersonal communication and the development of the child as an individual. There is a considerable number of methods that test the level of development of thinking and intellectual abilities. One of such techniques is the tests of Raven. They have become famous for their adaptability to the perception of children and ease of interpretation.

Description of the test of Raven

This technique is still called the "progressive matrix of Raven", in it the tasks are built on the principle of increasing complexity. These matrices are well understood by those children who understand the logic of their decision faster and more accurately. Children are provided with graphic objects that have a certain amount of characteristics necessary for decoding.

Raven's tests are arranged in five series. Each of them contains 12 tasks, each of which is more complicated than the previous one. This technique has a time limit, that is, 20 minutes are given for solving problems, but it is possible to pass the test without time. In this case, the result is interpreted using a special table.

For a specialist who conducts a study, you need to make sure that the children understand what they should do. Before you conduct tests Raven, you need to study the instruction and rules of conduct, then to compare the results with generally accepted standards. Color version of the method is carried out for children aged 5 to 9 years.

Five series of tests

The children's test of Raven has 5 difficulty levels, which are indicated in Latin letters.

Series A: here the child needs to determine the relationship in the structure of the task. It is necessary to supplement the missing part of the picture.

Series B: it is necessary to find an analogy between the pair figures. For this, the child determines the principle by which these pictures are distributed.

Series C: there is a complication of the figures, where the child should indicate their changes and pick up the missing fragment.

Series D: the tasks here are complicated by the fact that the figures are rearranged. It can occur both horizontally and vertically. The child needs to determine it.

Series E: the main pattern here is broken down into certain elements. The examinee must determine the required figures to complete the image. Here the researcher checks the development of the properties of thinking - analysis and synthesis.

Instructions for the test

The researcher should draw the children's attention to the fact that before the team starts the test they should not spy on the tasks. As soon as execution time comes to an end, all strictly on the command should finish. Carrying out tests by Raven, the expert slightly deciphers the goal in the instructions. To this end, he draws the children's attention to the seriousness of the research, encouraging them to conscientiously, deliberately and accurately carry out assignments. It can be noted that the methodology is intended to clarify the logic of children's thinking.

Explanation of results

This test can be interpreted from several positions:

• An estimate of the number of correctly solved tasks (10-point scale);
• Taking into account the difficulty and correctness in the results (19-point scale);
• A five-point scale with the signs "+" and "-";
• A qualitative blunder on the performance of the test: the solution is quick but with incorrect answers, it refers the child to the category of "speeders", slow, but accurate performance speaks of the child as "crap" or "slow-motion".

IQ for the Raven test is assessed at 5 levels of development:

1. Especially high - results over 95%.
2. Above average, estimates range from 75 to 94%.
3. Average - the result is 25-74%.
4. Below average - in the performance of the assignment estimates are 5-24%.
5. Defect of the intellect - getting the result below 5%.
