ATYPICAL CHILDREN. Atypical means irregular, or not conformable to type. Applied to children, it usually indicates those who are below normal mentally, or who are suffering from more or less abnormal conditions of the mind. (See MENTAL. DEFICIENCY.) "Atypical schools" are maintained in Washington, D.C., and other American cities, for children of this class. No attempt is made to maintain the ordinary school curriculum. The atypical children are taught as individual peculiarities require. They are not able, usually, to profit by any considerable amount of mental training, but frequently receive much benefit from various sorts of manual training, rug and basket weaving and other types of physical work.
