ObjectiveThe extensive use of two diverging personality taxonomies (the Big Five and HEXACO models) in contemporary research creates a need for understanding how traits connect to each other across taxonomies. Previous research has approached this at both a highly general (domain‐) level as well as at a highly specific (facet‐) level. The present report is the first to use the intermediate (aspect‐) level of the Big Five Aspect Scales (BFAS) to understand the connections between the two models.MethodWe explored these associations in a meta‐analysis of four samples drawn from three countries (total N = 1,586).ResultsWe observed that each HEXACO domain correlated ≥|0.51| with one or more BFAS aspects. Half of the aspects were more strongly associated with HEXACO facets than with HEXACO domains, sometimes markedly so.ConclusionAlthough many domains, aspects, and facets are similarly represented across the two models, this was not always the case. Researchers seeking to use one model to extend findings built primarily off the other should carefully consider how well represented their traits of interest are in the other assessment. Psychology instructors are encouraged to use the BFAS to illustrate the subtler distinctions between the Big Five and HEXACO models.

Overclaiming-in which individuals overstate their level of familiarity with items-has been proposed as a potential indicator of positive self-presentation. However, the precise nature and determinants of overclaiming are not well understood. Herein, we provide novel insights into overclaiming through 4 primary studies (comprising 6 samples) and a meta-analysis. Based on past empirical work and theoretical discussions suggesting that overclaiming may be the result of several processes-including an egoistic tendency to self-enhance, intentional impression managing behavior, and memory biases-we investigate various potential dispositional bases of this behavior. We hypothesized that overclaiming would best be predicted by a dispositional tendency to be curious and explorative (i.e., high Openness to Experience) and by a dispositional tendency to be disingenuous and self-centered (i.e., low Honesty-Humility). All studies provided support for the first hypothesis; that is, overclaiming was positively associated with Openness. However, no study supported the hypothesis that overclaiming was associated with Honesty-Humility. The third and fourth studies, where multiple mechanisms were compared simultaneously, further revealed that overclaiming can be understood as a result of knowledge accumulated through a general proclivity for cognitive and aesthetic exploration (i.e., Openness) and, to a lesser extent, time spent in formal education.

In the research reported here, we examined whether individual differences in authoritarianism have expressions in early childhood. We expected that young children would be more responsive to cues of deviance and status to the extent that their parents endorsed authoritarian values. Using a sample of 43 preschoolers and their parents, we found support for both expectations. Children of parents high in authoritarianism trusted adults who adhered to convention (vs. adults who did not) more than did children of parents low in authoritarianism. Furthermore, compared with children of parents low in authoritarianism, children of parents high in authoritarianism gave greater weight to a status-based "adult = reliable" heuristic in trusting an ambiguously conventional adult. Findings were consistent using two different measures of parents' authoritarian values. These findings demonstrate that children's trust-related behaviors vary reliably with their parents' orientations toward authority and convention, and suggest that individual differences in authoritarianism express themselves well before early adulthood.
