Mega- or meta-analytic studies (e.g. genome-wide association studies) are increasingly used in behavior genetics. An issue in such studies is that phenotypes are often measured by different instruments across study cohorts, requiring harmonization of measures so that more powerful fixed effect meta-analyses can be employed. Within the Genetics of Personality Consortium, we demonstrate for two c...

In this study, we examine additive and non-additive genetic contributions to the personality trait of extraversion in 1,689 Dutch twin pairs, 1,505 mothers and 1,637 fathers of the twins.

We use linguistic algorithms to measure the extraversion of company executives based on their speech patterns during conference calls. We find extraverted executives earn significantly higher salaries. Extraverted CFOs are more often promoted to CEO, and extraverted CEOs are more likely to serve on outside boards. Analyzing executive transitions, we find that firms with extraverted CEOs garner ...

Two groups (n = 86) of university athletes (contact, no contact) and two matched groups (n = 86) of non-athletes completed the Eysenck Personality Inventory (Eysenck & Eysenck, 1968). Extraversion did not vary significantly between athletes and non-athletes or between contact and no contact athletes, but it was higher for athletes compared to American college norms. For neuroticism, athletes sc...

The relationships between personality dimensions and aspects of auditory hallucinations in schizophrenics had been reported (Ramanathan 1984 a, 1984 b, 1984 c, 1985). Particularly, extraversion was found to be associated with coping behaviour in relation to auditory hallucinations in schizophrenics (Ramanathan 1984 c). Further exploration is necessary with regard to the relation between extrave...
