Working Memory is a critical aspect of our intellectual capacity. If anyone hasn't already seen the recent research study on Training Working Memory (http://www.pnas.org/content/early/2008/04/25/0801268105.abstract) (PNAS), you should check it out. Jaeggi's team recorded increases in mental agility (fluid intelligence) of up to 50% after 19 days of focused training with a dual n-back progressive method.

I was so impressed that I developed a software program using the same method so that anyone can achieve these improvements at home. The IQ Training Program
