So I looked at some of the literature on training programs on cognition; there have been a bunch. Again, I picked one that I thought said something, added something different from the others. Yesavage had published tons and tons of stuff on this topic. If you want to do a literature search and get stuff on that subject, put his name in. He has published probably 30 or 40 papers just on this topic alone or some version of it. In one of these projects they looked at 218 community dwelling elderly ranging from 55 to 87 and they gave them four 2-hour sessions of face-name association training and list-learning strategy training. And they had this idea, this study here was really trying to see well if I prepare people for this training, will it help them. So he trained people in imagery, he trained people in relaxation, or he trained them in imagery plus judgment and judgment means making a quick judgment on people’s facial figures; kind of how to look at things and how to make quick decisions on what I’m being shown in the training.
