Using mental imagery training to strengthen memory

There are two very cool things that came out of this new study from Sandia National Laboratories. 

The first is that the research team was able to predict test performance results just by monitoring the brain with EEG sensors while the person studied. Of the 23 participants, the computer model predicted which five people would perform best (using the EEG's to see how their brain memorized information). Sure enough, those 5 people remembered 72% of the words vs. only 45% compared to everyone else! After undergoing brain training, those five people performed even better on the memory tests!

The second interesting part involved splitting participants into 3 groups: a control group who got nothing; a group that went through "working memory" training to see if they could increase how much info they could handle at once (the average person can remember about 7 items at once); and a third group that practiced mental imagery strategy - thinking up vivid images to remembers words or pictures.

The results? The working memory group improved the task they'd trained on (remembering info for brief periods of time) but training didn't carry over to other tasks.

But the group that underwent imagery training improved on three of the five tasks.

My questions would be what kind of brain training exactly did these groups undergo? Were they on the computer or one-on-one intensive brain training? What would happen if they had longer, more intensive brain training (e.g. 24 weeks instead of three)?
