The training is aimed at seniors who want to take action against gradual cognitive decline. The focus of the training is on enhancing those mental skills that are subject to age-related deterioration. The program offers a variety of opportunities to train both short-term and long-term memory, practice learning new information, and recall from memory. However, even more importantly, it provides a large number of tasks to solve problems and activate thinking processes that are central to cognitive competence, which often significantly declines with age. The program counteracts this decline. Overall, the program includes 121 tasks that can be worked on and solved independently. A key advantage of the program is that seniors can carry it out on their own. There are instructions for completing the tasks and information about the background of the training.
