Personality and Season of Birth
Associations between season of birth and personality traits have been studied in non-clinical populations with mixed results. The present study explored the relationship between season of birth and personality traits separately for an Oceania-born sample (N=2808) and for a northern hemisphere born sample (N=482). Personality was assessed using a 50-item web-based version of the International Personality Item Pool (IPIP). No significant relationships between personality and season of birth were found in either sample. Researchers who have found personality differences between groups of individuals born in difference seasons have attributed these to a variety of factors, including effects of temperature variability on certain neurotransmitters known to influence personality, or sociological and other environmental factors. Our findings challenge the basis for these attributions and suggest that a more robust theoretical framework is required to explain possible season of birth influences upon personality in adult populations.
