Do people know how their personality has changed? Correlates of perceived and actual personality change in young adulthood

How much do we think our personality changes over time? How well do our perceptions of change correspond with actual personality change? Two hundred and ninety students completed measures of the Big Five personality traits when they first entered college. Four years later, they completed the same measures and rated the degree to which they believed they had changed on each dimension. Participants tended to view themselves as having changed substantially, and perceptions of change showed some correspondence with actual personality change. Perceived and actual change showed theoretically meaningful correlations with a host of variables related to different aspects of college achievement and adjustment

What is the value of orthodontic treatment?

Orthodontic treatment is as popular as ever. Orthodontists frequently have long lists of people wanting treatment and the cost to the NHS in England was £258m in 2010-2011 (approximately 10% of the NHS annual spend on dentistry). It is important that clinicians and healthcare commissioners constantly question the contribution of interventions towards improving the health of the population. In this article, the authors outline some of the evidence for and against the claims that people with a malocclusion are at a disadvantage compared with those without a malocclusion and that orthodontic treatment has significant health benefits. The authors would like to point out that this is not a comprehensive and systematic review of the entire scientific literature. Rather the evidence is presented in order to stimulate discussion and debate

Fluid Intelligence and Psychosocial Outcome: From Logical Problem Solving to Social Adaptation

While fluid intelligence has proved to be central to executive functioning, logical reasoning and other frontal functions, the role of this ability in psychosocial adaptation has not been well characterized.Lower fluid intelligence scores were associated with physical violence, both in the role of victim and victimizer. Drug intake, especially cannabis, cocaine and inhalants and lower self-esteem were also associated with lower fluid intelligence. Finally, scores on the perceived mental health assessment were better when fluid intelligence scores were higher.Our results show evidence of a strong association between psychosocial adaptation and fluid intelligence, suggesting that the latter is not only central to executive functioning but also forms part of a more general capacity for adaptation to social contexts

Self-esteem development across the lifespan

After decades of debate, a consensus is emerging about the way self-esteem develops across the lifespan. On average, self-esteem is relatively high in childhood, drops during adolescence (particularly for girls), rises-gradually throughout adulthood, and then declines sharply in old age. Despite these general age differences, individuals tend to maintain their ordering relative to one another: Individuals who have relatively high self-esteem at one point in time tend to have relatively high self-esteem years later. This type of stability (i.e., rank-order stability) is somewhat lower during childhood and old age than during adulthood, but the overall level of stability is comparable to that found for other personality characteristics. Directions for further research include (a) replication of the basic trajectory using more sophisticated longitudinal designs, (b) identification of the mediating mechanisms underlying self-esteem change, (c) the development of an integrative theoretical model of the life-course trajectory of self-esteem
