Abstract
In an effort to clarify and expand the theoretical foundation for behavioral researches on androgyny the present study, through an extensive literature review, attempted to establish personality structure as a function of masculine instrumentality (M) and feminine expressivity (F) in females. Results were strong and confirming, suggesting that considerable relationship may exist between certain sex role socialization practices and general personality development. In addition, the implications of instrumentality and expressivity for adjustment were investigated through a planned contrast of clinical and normal groups, with the expectation that feminine females would appear more frequently in the clinical group. However, results clarified that it is the lack of masculine instrumentality in the personality, not the feminine role per se, which is implicated in mental illness. These findings lend clarity to previous researches on androgyny and adjustment. Implications for feminine socialization and ego psychology are considered.
