Again, when you read this meta-analysis, what it comes down and says is, everybody is trained for the test, and yet they are showing some incremental change over time or at least not much decline compared to people that were controlled but it’s just for the test. It is begging the question “what about real life”. Now they did say a few other interesting things too; that training done in groups seemed more useful than individual training; working with younger participates was more effective than older; using shorter training sessions was more useful. And they theorized that people just get tired or bored if given too long of a training session. And they ranged dramatically; there were 20 minute sessions and there were three hour sessions and everything in between. And he found some studies that showed when pretraining was provided people improved their treatment gains overall.
