Unformatted text preview: reported decreases in authoritarianism, ethnocentrism, and dogmatism over the first 2 years of college. Stewart (1964), in a 4-year longitudinal study of Berkeley students, found decreases in authoritarianism coupled with increases in complexity of outlook and originality. Sanford (1956) reported that Vassar College students became less conservative and more tolerant of individual differences. Likewise, Mortimer et al. (1982) found increases in unconventionality during college, and both Nichols (1967) and Baltes and Nesselroade (1972) reported significant increases on the 16PF scale of intelligence in longitudinal studies of college students. Helson and Moane (1987) reported increases in psychological mindedness in a sample of women from ages 21 to 27, and McGue et al. (1993) reported increases in absorption in a sample of twins from ages 20 to 30. Haan et al. (1986) found significant increases in cognitive commitment for women from Personality Change 621 ages 17 to 30. Thus, many traits associated with Openness to Experience appear to increase during young adulthood. A second domain that shows evidence for mean-level increases in young adulthood corresponds to the Big Five dimension of Conscientiousness. In a longitudinal study of adolescents, Stein, Newcomb, and Bentler (1986) reported increases in measures of orderliness, law abidance, and diligence. Haan et al. (1986) found increases in both men and women in dependability from age 17 to 30. Helson and Moane (1987) reported increases in self-control from ages 21 to 27 (see also, Roberts, Helson, & Klohnen, in press). Holmlund (1991) found increases in the need for order from ages 15 to 25. In addition, McGue et al. (1993) found increases in one’s sense of control from age 20 to age 30. However, the evidence is not uniform for traits related to Conscientiousness. For example, Sanford (1956) reported that students became more inclined to express their impulses during college, and Nichols (1964) reported decreases in measures of deferred gratification and “supereg...
