Subcultural mental handicap.

Some conceptual problems in relation to the interaction of genetic influence and social disadvantagement are discussed, and some of the results of a study of 144 families with mentally handicapped children reported. The work of Heber and his associates in Milwaukee is briefly reviewed, and the Edinburgh data discussed in relation to the study in Aberdeen by Birch et al. (1970). Possible strategies for intervention are considered. [ABSTRACT FROM AUTHOR]
