The Binet-Simon test is the most common method for quantifying the level of development of intellectual abilities.
Appearance history
Developed in 1905 by A. Binet and T. Simon by order of the Ministry of Public Education of France in order to screen out children who are not sufficiently developed to study in a mass school. Initially, the test contained 30 tasks, which were selected according to the degree of difficulty so that they could be solved by 75% of children of a certain age, whose mental development could be considered normal. The number of correctly solved tasks characterizes the so-called mental age.
Test modifications
The most famous modification was developed by L. Theremin at Stanford University (USA); the so-called Stanford-Binet test he created is the most recognized method for diagnosing intelligence. Based on it, the IQ is calculated. However, the practical use of this test, like most
of such methods, allows us to quantify individual differences in mental abilities without revealing their nature and development prospects. This makes it difficult to use the test results in making a psychological diagnosis and predicting the development of intelligence.
