Extraversion, neuroticism, and date of birth: a Southern hemisphere study.
The aim of this study was to determine whether variations in Eysenck Personality Inventory (EPI) scoring among zodiacal birth groups follow a similar pattern for Ss born in the Southern hemisphere to that which has been reported for Northern hemisphere Ss. EPI and birth data were obtained from 450 adult Ss, of whom 338 were New Zealand born. Results for Extraversion significantly matched British findings (p less than .01). Results for Neuroticism were ambiguous. It is concluded that seasonal and climatic influences are unlikely to explain the Extraversion differences between birth groups.
