Brain training does not make you smarter

Moreover, in the so-called intelligence reports increase is to be verified at any time, especially how much the amount of training required in order to achieve appropriate results. North Carolina to study at the University of Ronaldo, “Preschool Early Intervention Project” (Abecedarian Early Intervention Project), for children from low-income families make strong intervention from infancy to 5 years old lives, including educational games. Meanwhile, the control group received social services, health care and nutritional supplements. In the final of the study, all children receive IQ test, the average score of the experimental group than the control group, 6 points – interpretation from the system point of view, this is a moderate impact.

For the concept of variability in intelligence began to change in the 21st century. A major driving force is Susanne Jaeggi, a postdoctoral researcher at the University of Michigan, now a professor at the University of California, Irvine, who led a study in 2008, and subsequently serialized in the record of the meeting of the National Academy of Sciences (Proceedings of the National Academy of Sciences). Jaeggi and colleagues to make a number of young people with the ability to complete a test of reasoning, in order to assess the “fluid” intelligence – the ability to solve novel problems.

Participants were assigned to a control group or an experimental group, the experimental group participants practice a computerized task called “dual n-back”, this task requires a person to control both the auditory and visual information flow ( This task is challenging, moderate difficulty.) Finally, all participants accept a different version of the reasoning test to see if there is any impact on the training of fluid intelligence.

The results are shocking. Experimental group not only in reasoning tests show more progress, but the degree of improvement is sufficient to have an impact on people’s lives. Senior scientist at the University of Michigan research team of John Jonides, explained that there is also a dose-dependent relationship: “We found that four weeks of training can allow fluid intelligence to produce significant changes … we have proved that you train short-term memory. longer, your IQ increased more.
