Can Brain Training Games Improve IQ Test Scores?

Now, brain-training games have been thought to improve intelligence. However, recent studies have proved that this may not be true. In fact, it’s more likely that the “intelligence” from these kinds of games is a placebo, and people only think they have become smarter. Meaning, when people know they are in a “brain training” research group, they score better on intelligence tests because they expect the training to work. This bias skews the results and one research group tested the theory, putting 25 people in a “brain training and cognitive enhancement” study and 25 more people into what they simply dubbed “a study”. Both groups played the same game for one hour, but those who believed they were brain training performed higher on their IQ tests. [1]

However, there is something to do to actually become more intelligent: Learn something new. Brain training games aren’t all they cracked up to be because people tend to just get better at the game and that intelligence doesn’t carry over into other aspects of their life. However, if they learned something about themselves, like a certain strength, weakness, or preferred thinking method, that knowledge could be invaluable. But if you want real “brain training,” learn another language, or how to play an instrument, or read on a regular basis. [2]
