Patterns of cumulative continuity and maturity in personality and well-being: Evidence from a large longitudinal sample of adults.

ABSTRACT: Longitudinal studies have shown that, on average, agreeableness and conscientiousness increase and neuroticism decreases in adulthood, a phenomenon dubbed the "maturity principle". The rank-order stability of personality also tends to increase with age, sometimes called the "cumulative continuity principle". It remains unclear, however, whether the rank-order stability and average levels of different types of well-being increase with age. Therefore, using a large longitudinal sample of adults (N > 6,000), the present study aimed to replicate studies of the maturity and cumulative continuity of the Big Five and test whether these developmental trends extend to different types of well-being. The present study demonstrates that, although many types of well-being exhibit developmental trends that are similar to those of the Big Five, distinguishing the general tendency toward all forms of well-being from variation in specific kinds of well-being can illuminate potentially important developmental differences.

Project description:Infant temperament is theorized to lay the foundation for adult personality; however, many questions remain regarding personality in infancy, including the number of dimensions, extent to which they are adult-like, and their relation to other outcomes, such as mental and physical health. Here we tested whether adult-like personality dimensions are already present in infancy in a nonhuman primate species. We measured personality and subjective well-being in 7-month-old rhesus macaques (N = 55) using the Hominoid Personality Questionnaire and Subjective Well-Being Questionnaire, both of which were developed for adult primates based on human measures. Multiple human raters, who provided infants with daily care since birth, independently rated each infant. We found high interrater reliability. Results from a parallel analysis and scree plot indicated a five component structure, which, using principal components analysis, we found to be comprised of dimensions relating to Openness (e.g., curiosity, inquisitive, playfulness), Assertiveness (e.g., dominance, bullying, aggressive), Anxiety (e.g., vigilance, fearful), Friendliness (e.g., sociable, affectionate, sympathetic), and Intellect (e.g., organized, not erratic). These components are largely analogous to those in adult macaques, suggesting remarkably stable structural personality components across the lifespan. Infant macaques' subjective well-being positively correlates with Openness and Assertiveness and negatively correlated with Anxiety, similar to findings in adult macaques and other primates. Together, these findings suggest that, in macaques, infant personality dimensions may be conceptually related to adult personality and challenge the view that infant temperament may be disorganized and not as meaningful as adult personality. Further research is necessary to explore the antecedents, predictive validity, and stability of these personality components across situations and with development.
