ABSTRACT
The idea of a comprehensive, interdisciplinary socialisation theory is based on the analytical double perspective of the explanatory variables 'society' and 'individual'. To outline a comprehensive socialisation theory, an exemplary model encompassing the individual theories is required that serves as the frame for a 'meta-theory'. The term 'productive processing' expresses that the individual effort to cope with the internal and external reality is an active process in which people choose their own way in line with their own requirements and needs. Processing is 'productive' because it results from the specific, individual way of dealing with the internal and external conditions. A person's subjective perception includes the concept of body and psyche, as well as of the social and physical environment. Internal and external reality is always experienced through the filter of one's own subjective perception, and therefore every concept of the internal and external reality is individual.
