[The contribution of biosocial factors to social group specific socialization (author's transl)]

The purpose of the article is to contribute to the extension and differentiation of the discussion about social group specific socialization. This is done in such a way that the sociological analysis is no longer restricted to sociocultural deprivation, but extended to the relationships between biological and social facts which can also be considered to be dependent upon the overall structure of society. The example of malnutrition is used to demonstrate to what extent biosocial variables add - in a complicated interplay with socio-cultural deficits - to the decrease in sociability and socialisation opportunities of the children in question. This applies particularly to learning disabled children in our country.
