THE DATA FROM PREVIOUS STUDIES WERE USED TO DETERMINE IF THERE WERE DIFFERENTIAL NONINTELLECTUAL (PERSONALITY) CHANGES IN YOUNG ADULTS WHO DIFFERED MARKEDLY IN MEASURED ACADEMIC APTITUDE. THREE OF THE FORMER STUDIES WERE FOR A 2-YEAR TEST AND RETEST TIME PERIOD, AND TWO WERE FOR A 4-YEAR TEST AND RETEST TIME PERIOD. COMPARISONS OF NONINTELLECTUAL CHANGES BETWEEN HIGH- AND LOW-APTITUDE GROUPS OF MALES AND OF FEMALES WERE CONDUCTED. THIS RESULTED IN 40 POSSIBLE COMPARISONS OF THE CHANGES OVER TIME FOR HIGH- VERSUS LOW-APTITUDE GROUPS. THE ETHNOCENTRISM SCALE, THE DOGMATISM SCALE, THE AUTHORITARIANISM SCALE, THE CALIFORNIA PSYCHOLOGICAL INVENTORY, AND THE STUDY OF VALUES WERE THE INSTRUMENTS USED TO OBTAIN THE SCORES FROM THE YOUNG ADULT SUBJECTS. THE MAJOR CONCLUSIONS DRAWN WERE THAT YOUNG ADULTS OF HIGH APTITUDE EXHIBITED MORE "PSYCHOLOGICALLY POSITIVE" NONINTELLECTUAL CHANGE OVER TIME, AND THE DEVELOPMENT IS SIMILAR IN TREND TO PERSONALITY CHANGES OF COLLEGE STUDENTS IN GENERAL.
