This study was undertaken in the belief that a greater relationship would be revealed between the Rorschach and intelligence test scores if the factors in the Rorschach which have been found in the past to be related to intelligence could be compared as a whole with scores obtained on mental tests. The purpose of this study was to determine whether it could be demonstrated that a higher degree of relationship does exist between several of the Rorschach factors, considered as a whole, and intelligence as revealed by the California Test of Mental Maturity.
