Summary
Studies which have previously examined the relationship between ego and moral development have found substantial correlations. However, they have used both child and adult Ss, thereby focusing on maturational aspects of development. Also, they have employed linear parametric correlations, which may have been inappropriate for the scaling level of the data. The present study employed only adult Ss, and a nonlinear, nonparametric measure of correlation was developed to examine the relationship between ego and moral development scores. Nonparametric analysis of the variance revealed a significant relationship between scores on the two measures and yielded a moderately high nonlinear correlation coefficient (η2 = .42).
