1. This test was created by the British psychologist J.C.Raven in 1938, and is used to test a person's observation and clear thinking ability all over the world. It is a pure nonverbal intelligence test, so it is widely used in borderless intelligence/reasoning ability test, and belongs to asymptotic matrix diagram. The whole test consists of 60 pictures and a progressive matrix of five units. Each unit has different requirements for intelligence activities. Generally speaking, the structure of matrix is becoming more and more complex. The evolution from one level to multiple levels requires a gradual process of thinking operation from direct observation to indirect abstract reasoning.
Second, the scope of application:
(1) Applicable age range: 6 to 70 years old.
(2) Scope of applicable personnel: People from different occupations, countries and cultural backgrounds can use it, even deaf-mute people, patients who have lost a certain language function and people with psychological barriers can use it.
Three. Intelligence level: expressed as a percentage level.
Level 1: the standard score of the test is equal to or greater than 95% of the norm of the same age, which is a high level of intelligence.
Grade II: The test standard is between 75% and 95%, and the intelligence level is good.
Level 3: the test standard is between 25% and 75%, and the intelligence level is medium.
Level 4: the test standard is between 5% and 25%, and the intelligence level is medium or low.
Grade five: the standard score of the test is less than 5%, which means mental retardation.
In addition, A, B, C, D and E all have the correct number of questions:
Answer: It reflects the ability of perception and discrimination (question *** 12).
B: Comparative ability reflecting similarity (question *** 12)
C: Demonstrate the ability of comparative reasoning (question *** 12)
D: the ability to reflect the series relationship (question *** 12)
E: Reflecting the ability of abstract reasoning (question *** 12)
Through the score structure of five aspects, it is helpful to understand the intellectual structure of the subjects to some extent.
