This paper presents: (1) a definition of values; (2) a measure of moral values which seems to have adequate conceptual and psychometric properties; and (3) evidence concerning the personological correlates of mature moral judgment. Values are defined as the standards used in moral evaluations and the criteria for choosing rules of conduct. Using a brief, semi-projective task, moral judgments were elicited from undergraduate fraternity members. These were scored for maturity of moral judgment. Persons whose moral judgments were rated as mature tended to be sensitive to injustice, well-socialized, empathic, autonomous, and they based their judgments on intuitive notions of "goodness."
