Some kinds of mental skills naturally decrease as people get older. Yet research seems to show that some training can improve such skills. A recent study also appears to show that the good effects of training can last for many years after that training has ended. Researchers at Johns Hopkins University in Maryland wanted to learn how long memory and thinking skills would last in older people who trained to keep them. The people were part of a 10-year research project. They were taught methods meant to improve their memory, thinking and ability to perform everyday tasks. More than 2,800 volunteered for the study called ACTIVE or Advanced Training for Independent and Vital Elderly. Most started the training when they were more than 70 years old. The volunteers took one of several classes meant to help them keep their mental abilities. One class learned skills including how to remember word lists. Another group was trained in reasoning. A third group received help with speed of processing — speed of receiving and understanding information. A fourth group, the control group, did not get any training. Earlier results had established that the training helped for up to five years. Lead researcher George Rebok now says the training continued to be effective a full 10 years later. The research team found that the people trained in reasoning and speed of processing did better on tests than the control group. The effect on memory seemed not to last as long. Still, people who took part in any of the three classes generally reported fewer problems in daily activities than the control group.
