    Alfred Binet was the first who addressed the question of intelligence development and how to evaluate it in numerical terms. He tried to implement general laws in psychology and started with intelligence assessment. The study was carried out jointly with Théodore Simon, and testing was named the intelligence scale. These works enabled impartial evaluation of human intelligence.

    It is impossible to imagine today’s psychology without IQ tests. This term was introduced by William Stern who successfully improved a methodology developed by his colleagues. IQ tests present the mental development level numerically, and also determine deviations and the range of normal values.

    1920 were value-creating for development of psychology in the Soviet Union. Scientists were actively studying neuropsychology as a branch of medicine. This science studies mechanisms of damages in various brain sections that may lead to deterioration of cognitive functions.

    Every year, new tests designed for human intelligence evaluation appear. Realization of how mentality works enabled specialists to assess and develop it. In 1938, Raven and Penrose developed a test dedicated to evaluating logic skills and creative thinking. The test was appropriate for all people from small children to seniors. Within the Raven’s matrices test, an examinee is shown a set of cards with images on them. The images have certain relations that the examinee should found. The difficulty is adapted to the examinee age.

    The first test that evaluated child’s mental level was developed by David Wechsler in 1939. 16 years later, the methodology was enhanced, and this way an analog of modern IQ testing was developed. Some tasks of the Wechsler test are used as children’s brain games even today.

    N-Back Task

    Continuous Cycle Tasks

    The method was originally developed to assess memory level of various-age people. The examinee is presented with a sequence of stimuli, and the task consists of indicating when the current stimulus matches the one from n steps earlier in the sequence. This way the examinee demonstrates information processing skills. The test is the most efficient memory improvement instrument even today, which also expands thinking horizons, making the examinee concentrate on both current and past events.

    George Miller was the author of a noteworthy human memory study in which all the examinees showed the same results. His works helped find out that at the average, a person can immediately memorize 5 similar words, 7 letters, 8 decimal numbers, and 9 binary numbers. Miller’s book stated that human memory volume equals 7 bits. Up to now, these studies are used to efficiently develop memory of children and adults.

    Paul Bach-y-Rita is the creator of a device that enhanced efficiency of rehabilitating people with partial brain damage. Attached to the tongue, the device improved equilibrium sense of people that suffered a cerebral accident. The device enabled the scientists to look at how brain works with a fresh sight, and start neuroplasticity studies. This term stands for brain’s flexibility and ability to evolve or change under the influence of various factors.

    Philip Michael Corsi has developed the method for efficient development of visual memory and spatial thinking. The process of the Corsi block tapping task requires the subject to observe the sequence of blocks ""tapped"" (or lit up in the computer version), and then repeat the sequence back in order. Then, Corsi test was renamed into memory matrices. This simulator remains one of the most popular ones. Children can play a junior version of this simulator. Play Memory Matrices.

    Flanker Task

    Testing allows you to assess and develop visual attention. A person evaluates the location of several objects in space simultaneously, and then chooses the main requested characteristic. Thus, the ability to notice the most important parameter improves, with the discarding of secondary ones. In this case, the queries in the test are constantly changing, which requires increased concentration and a high level of switching thinking

    Develop memory, attention and thinking with games.

    In 2014, a group of scientists from Lomonosov Moscow State University is launching a complex resource that allows training various parts of the brain. The site is rapidly becoming popular among users and in two years has already passed the mark of 250 thousand users. The success of the resource continues to grow thanks to the effectiveness of the developed individual training sessions.
