The article specifically mentions speed training as the activity that actually produced measurable results while memory training or reasoning training did not. The theory is that this type of activity engages different brain structures.
The other potential explanation is that it's because the speed task increases in difficulty as you get better at it. I'm hoping that's the real reason.
I'm sure there will be more follow up research. In the meantime, seems like fast paced games are likely a good activity to engage in.
