Describing and quantifying animal personality is now an integral part of behavioural studies because individually distinctive behaviours have ecological and evolutionary consequences. Yet, to fully understand how personality traits may respond to selection, one must understand the underlying heritability and genetic correlations between traits. Previous studies have reported a moderate degree o...

Studies on personality traits and insomnia have remained inconclusive about which traits show the most direct associations with insomnia severity. It has moreover hardly been explored how traits relate to specific characteristics of insomnia. We here used network analysis in a large sample (N = 2089) to obtain an integrated view on the associations of personality traits with both overall insomn...

The Five Factor Obsessive Compulsive Inventory (FFOCI) was developed in part to facilitate a shift from the categorical classification of personality disorder to a dimensional trait model, more specifically, the five-factor model (FFM). Questions though have been raised as to whether obsessive–compulsive personality disorder (OCPD) can be understood as a maladaptive variant of FFM conscientious...

In this paper, we study the relationship between language use on Twitter and personality traits. Specifically, we want to know how various linguistic features correlate with each personality trait and to what extent can we predict personality traits from language. We gather personality data from Myers-Briggs Type Indicator (MBTI) personality test which contains thinking, feeling, sensation, int...

Personality traits and their relation with emotional intelligence and psychological ownership (PO) have to be considered in public-sector organizations, because employees who work in the public sector may have fewer mechanisms to increase their feelings of PO toward their organization. Thus, with regard to conditions of public organizations, more attention should be paid to structural and organ...

Heritable variance in psychological traits may reflect genetic and biological processes that are not necessarily specific to these particular traits but pertain to a broader range of phenotypes. We tested the possibility that the personality domains of the five-factor model and their 30 facets, as rated by people themselves and their knowledgeable informants, reflect polygenic influences that h...

The role of personality traits in the decision to start a business and to maintain it successfully is discussed controversially in entrepreneurship research. Our meta-analysis builds upon and extends earlier meta-analyses by doing a full analysis of personality traits that includes a comparison of different traits from a theoretical perspective and by analysing a full set of personality predict...
