Jane Loevinger

Jane Loevinger Weissman (February 6, 1918 – January 4, 2008) was an American developmental psychologist who developed a theory of personality which emphasized the gradual internalization of social rules and the maturing conscience for the origin of personal decisions. She also contributed to the theory of measurements by introducing the coefficient of test homogeneity. In the tradition of developmental stage models, Loevinger integrated several "frameworks of meaning-making" into a model of humans' constructive potentials that she called ego development (or in German, ''Ich-Entwicklung''). The essence of the ego is the striving to master, to integrate, and make sense of experience. She also is credited with the creation of an assessment test, the Washington University Sentence Completion Test. Provided by Wikipedia
