Unformatted text preview: o.” In general, though, the preponderance of evidence points to increasing Conscientiousness in young adulthood.
In the domain of Extraversion, the longitudinal findings in adolescence
and young adulthood are quite mixed. Several studies have found increases in traits related to Extraversion. For example, Stewart (1964)
reported increases in dominance and decreases in introversion in a
longitudinal study of college students. Holmlund (1991) found increases
in dominance and decreases in succorance in a longitudinal study of
females from age 15 to age 25. Similarly, Carmichael and McGue (1994)
found increases in Extraversion in a study of twins from ages 16 to 35.
In contrast, Viken, Rose, Kaprio, and Koskenvuo (1994) found decreases
in Extraversion in young adulthood for both male and female twins. In
addition, Nichols (1967) reported decreases in dominance during college. By far the most common finding is no change in positive emotion
in young adulthood. For example, Nichols (1967) found no systematic
change in sociability and surgency. Haan et al. (1986) reported no
systematic increases or decreases in assertiveness in young adulthood.
Helson and Moane (1987) reported no changes in dominance and social
poise in the Mills Longitudinal study of women from ages 21 to 27.
Watson and Walker (1996) found no change in positive affect in their
7-year follow-up of college students. Finally, in a longitudinal study of
twins that used the MPQ, McGue et al. (1993) found no increases or
decreases on measures of social potency and social closeness. Taken as 622 Robins et al. a whole, the longitudinal research to date indicates that Extraversion does
not show normative change in young adulthood.
With regard to Neuroticism, the results of previous studies point to
either no change or a decrease. In college student populations, Nichols
(1967) failed to find normative change on scales measuring anxiety and
tension, and Crook (1943), in a 6-year follow-up of college freshman,
failed to find changes on the Thurstone Personality Schedule, a measure
tapping aspects of neuroticism. Several studies have also failed to find
changes in young adulthood for measures of dispositional...
