Personality development in adulthood

Most of this research sounds like common sense. I remember my pediatrician reminding me that children are born with their personalities, same as eye color, intelligence, athleticism, etc. Check the webpage of Brent W. Roberts, University of Illinois, College of Liberal Arts and Sciences, who was featured in the last U of I LAS News.

Highlights of Recent Findings of Brent W. Roberts

Personality traits predict mortality, divorce, and occupational attainment as well as, if not better than socioeconomic status and cognitive ability (Roberts, Kuncel, Shiner, Caspi, & Goldberg, in press).

Personality traits continue to change in middle and old age (Roberts, Helson, & Klohnen, 2002; Roberts, Walton, & Viechtbauer, 2006). Specifically, people become more socially dominant, conscientious, and emotionally stable as they age.

People who are engage in counterproductive work behaviors (e.g., fighting, stealing, malingering) become more more alienated and less controlled than people who do not engage in counterproductive work behaviors (Roberts, Bogg, Walton, & Caspi, 2006).

People who become more involved in work and stay in stable marriages increase on measures of conscientiousness over time (Roberts, Caspi, & Moffitt, 2003; Roberts & Bogg, 2004).

People change their perception of their environment more than they change their self-perceptions over time (Harms, Roberts & Winter, 2006).

Goals for investments in work and marriage are related to increases in agreeableness and conscientiousness in college (Roberts, O'Donnell, & Robins, 2004)

People who are more conscientious avoid most of the risky behaviors that lead to premature mortality and participate in the positive health behaviors associated with longevity (Bogg & Roberts, 2004).
