The study caused a sensation. Once released, has been cited. Jaeggi’s research has now been cited more than 800 times – for study only published a six-year, this is a staggering figure. “Discover” magazine, said the survey found that in 2008 one of the 100 most important scientific discoveries, psychologist Robert Sternberg- over 1500 of publications on intelligence, claiming that the study seemed “to solve by some meaningful measurements to prove whether fluid intelligence can be trained controversy. ”
Not everyone was convinced. In fact, Jaeggi study just released soon to become 20 most wanted to be a psychologist to test its repeated experiments in the first place. First, let’s skeptics are hesitant to announce the increase in volume to the incredible intelligence. Studies such as early intervention programs enlightenment requires years of intense intervention in order to improve the value of a few IQ points. Jaeggi and colleagues found, suggesting that the only value you can put in a few hours to improve IQ six points.
The study also has serious flaws, making it difficult to interpret the results. One problem is that there is no placebo control group, ie, no one accepted not to improve intelligence to the desired training mission groups. (Placebo group were administered with the drug be administered to the experimental group comparison is made of sugar pill.) However, in the control group is a “non-contact” group, which means that the group of people is simply twice reasoning test, and During this period no longer in contact with the investigator. Thus, the experimental group showed the possibility of change for the better in reasoning tests, simply because they are expected to better performance, this possibility can not be excluded. More complex is the reasoning test acceptance among different experimental groups; some participants received 10 minutes of testing, while others received 20 minutes of the test. Ultimately, Jaeggi and colleagues used a test run only if intelligence is improved. People said that after the training, in a reasoning test in better performance, it does not mean they become smarter – it just means they progressed in this reasoning test inside.
