Over-50s can still make long term gains in cognition – if they approach the learning ot new skills as a child would. That is the surprising conclusion of researchers at University of California Riverside. They have found that one year after completing class and homework for about 15 hours a week over three months, participants in two studies tested significantly higher for cognitive functions than before they began the process. Those recruited for the research had to be at least 55 and their median ages were 66 in the first study and 69 in the second.
