Age differences in implicit and explicit personality traits

Past research suggests that personality differs by age—older adults tend to be more conscientious, agreeable, and less neurotic than younger adults. However, most of these studies have used self-report measures of personality which may be influenced by people's motivations to appear socially desirable that also change over time. If these changing motivations affect the validity of personality measures, our understanding of age differences in personality may need to be revised. In the current study (N = 12,702), we examined age differences in implicit (i.e., IAT-based) and explicit (i.e., traditional self-report) measures of personality. Although we found some heterogeneity in the exact non-linear age patterns of personality across different measures, the age patterns were largely consistent across implicit and explicit measures of personality. •Socially-desirable responding may influence our understanding of personality change.•Implicit personality measures may help overcome this limitation.•Implicit & explicit measures showed similar patterns of change across the lifespan.•Both measures show evidence of personality maturation.
