[Interrelationship of motivation and barriers in the learning process in old age (author's transl)].

Started from the concept of lifelong learning it is discussed that the relation between motivation and barriers or obstructions has important influence on learning in old age. Even if differential view has been regarded, in general we may suppose that motivation will have a decreasing tendency and barriers an increasing tendency in old age. This concept is seen together with Welford's Cost- and Benefit-Theory (1976), discussed for Motivation, Capacity, Learning and Age. Consequences would be to look for measures to increase the motivation and decrease the barriers as far as possible.
