ABSTRACT
Many of these activities try to increase or maintain skills of concentration, dexterity and memory. They can be useful learning activities for children and mentally handicapped people, and for long-term patients being rehabilitated to leave an institution after many years. Some of them are also useful for elderly people with senility problems, in helping them to retain their hold on ‘reality’ (especially if they have to live in an institution). Even more important, they can use experiences people may have had during their lives, and reaffirm their personal value in remembering what they have done.
