The problems of establishing both quantitative and qualitative deficits in the behavioural profiles of various diagnostic subcategories of developmentally-disabled children are discussed in a developmental context. Examples of clinical experimental studies from the literature concerned with the syndrome of early-onset psychosis are used to illustrate the importance of methodologically controlling for maturational variables. Methods of appropriate matching of control groups are suggested which should facilitate the delineation of specific and general deficits in subgroups of developmentally-delayed children.

The term “more appropriate communication” appears in more than 400 scholarly articles (according to Google Scholar). I examined the first 100 scholarly articles that pertained to communication between humans (rather than communication between computer networks). The question I sought to answer was who, according to the scholarly literature, bears responsibility for achieving “more appropriate communication?” Of the 100 scholarly articles examined, only a slim minority, N=7, imply that “more appropriate communication” is a responsibility shared among two or more communication partners, and most of these articles address “more appropriate communication” between literal peers, such as undergraduate students with other undergraduate students. The majority of scholarly articles, N=61, imply that the responsibility for “more appropriate communication” lies with the more powerful communication partners (i.e., people who have more status, experience, or resources). The remaining third of the scholarly articles (N=32) imply that responsibility for “more appropriate communication” lies with the less powerful communication partners, and these less powerful communication partners are frequently children with developmental disabilities. I conclude by suggesting that the responsibility for “more appropriate communication,” particularly with developmentally disabled children, either should be assumed by the more powerful communication partners or should be shared.

20 profoundly retarded children (4 to 12 yr.) were trained, using a variety of relaxation and tension activities designed to help them differentiate and gain control of the toileting musculature. Operant techniques were used to reinforce appropriate urination. The post-training scores of the experimental and control groups differed significantly for both accidental and appropriate urination.

26 children with diagnoses of autism and 22 children with diagnoses of childhood schizophrenia or a variant thereof were compared on the variable of winter birth. Analyses showed that autistic children had a higher proportion of winter births than schizophrenic children. These findings are related to other research linking winter birth to negative-syndrome adult schizophrenia.
