“…Others (e.g., Tizard, 1970) report that sex differentials are more prominent at the margins of the categories (among the milder forms of retardation) than the more serious types in which both genders would be judged incapable of performing adult roles. For example, a recent study (Tudor et al, 1979) reports greater proportions of males than females being institutionalized, with the differences more pronounced for the milder rather than the more seriously retarded. The authors have not addressed the role of stigma in this process, however, and the differences in confinement and detection could be more a function of disruptive and disturbing behavior among males than gender-based expectations of behavior.…”
