Does brain training work? There are a number of conflicting studies in the literature see Guardian games blog for example. There has recently been a lot of interest in the Ninetendo DS brain training game although I am not aware of any published work on it’s effectiveness (but see this BBC site article for some anecdotal evidence.) I have just come across a good study in the British Journal of Educational Technology by Miller and Robertson 2009 showing improvements in self esteem, and accuracy and speed of mental maths using the DS brain training games (Also see comment from Derek Robinson below). I note that in this study only the specific task of mental maths improved, which is partly what the DS program trains.  I don’t think there is evidence that the DS BT works across different areas to train the brain as a whole.  Nintendo brain training does not train specific brain areas or functions and does not fit with contemporary neuropsychological theory.  It is a more broad brush approach.   In reality the brain has numerous functions linked to different anatomical areas and trying to train the whole thing at once is, I think nonsensical. Brain training will have to become a lot more targeted if it is to work.

There is some evidence that targeting specific areas can be effective. The key candidate at the moment is working memory. Working memory is the ability to hold information in mind i.e mental arithmetic , remembering lists of instructions etc. Working memory is associated with the dorsal-lateral pre- frontal cortex in the brain. There is an interesting paper in PNAS that shows that training working memory resulted in increased IQ levels. You can access the training site and try it for yourself here for free. Also there is some interesting new research on improving working memory using a computer game, which is due to be published soon and which I will report on here.

The key to brain training is to know how the brain works and how it develops and then to target set areas. My own company Neurogames produces brain training games based on the science of brain and psychological development. The games are targeted on areas where I think we should be able to produce change and where I think brain plasticity exists. It is important to understand how the brain and it’s functions develop as this holds the key to what can potentially change. I am carrying out research on this at the moment. If we can show through good science and based on solid neuropsychological theory that change can occur and how it occurs, then there is the possibility to revolutionize how we learn.

Note: Update 20.4.10 a new large scale study published in Nature suggests that Nintendo brain training is not effective in producing transferable cognitive benefits.  Initial nature study is published here
