Animal personality is a fairly new branch of biology and has been defined as a difference in behaviour between individuals that is relatively consistent across time and/or context. What researchers now are interested in is to find out what it is that creates and maintains this relatively consistent difference between individuals. One possibility is the stress hormone, corticosterone. I have in this report summed up some of the available studies regarding animal personality and its possible correlation to corticosterone. The personality traits that have been reviewed in this report are boldness, exploration, activity, aggressiveness and sociability. The result of these studies show that boldness have both a negative and a positive correlation; exploration showed different correlations between studies; aggressiveness showed different correlation between different animal types and sociability showed both a negative and none correlations. The only one that I could not determent the correlation for was activity. The research regarding animal personality and corticosterone can be of use when looking at animal welfare and how stress affects different individuals. This can give us a direction in our work to reduce stress for animals in research facilities and food production.
