People are living longer, and in better physical health, than at any other time in history. But what of their mental health? Does it decline with age, offsetting the gains made in physical health and longevity? Can it be maintained? Can it improve? A review of the literature suggests that cognitive decline is not universal, pervasive, or irreversible. It also demonstrates that older adults can benefit from cognitive training. The challenge, however, is to provide such training in ways that are acceptable to older adults. The answer is to be found, firstly, in research that identifies best practices for cognitive skill development in ecologically valid activities involving older adults, psychologists, and adult educators. These best practices can then serve to assist educators to design continuing education programs and other activities that are readily accessible, affordable, and enjoyable.
