In the present paper the results of an experimental arrangement of tests are represented allowing preliminary statements on the age dependency of certain aspects of the social ability to learn within the framework of comprehensive investigations to determine the biological age of man. The relevance to employ precisely these methods results from the necessity to make measurable in particular also those spheres of human personality which refusing pure deficit models of old age are an expression of the processes of restructuring and maturing which represent the aging of man. The conditions for the use of this method and the limited possibilities of interpretation of the results in juvenile and elderly citizens are pointed out. They allow the conclusion that at an older age certain aspects of the social ability to learn can be more strongly pronounced than in young people. From the methodical point of view this experimental arrangement seems particularly suited to complete efficiently clinical-functional and psychophysiological measuring methods for the complex determination of biological age.
