Personality in animals/ethology/Gosling: The most comprehensive review to date of the animal personality literature identified personality studies in sixty-four different non-human species (Gosling 2001)(1). Since that review, studies of personality in numerous other species have emerged, ranging from water striders (Sih and Watters 2005)(2), lizards (Cote and Clobert 2007)(3), and squid (Sinn, Gosling and Moltschaniwskyj 2008)(4), to tropical fish (Brown, Jones and Braithwaite 2005)(5), geese (Kralj-Fiser, Scheiber, Blejec et al. 2007)(6) and orangutans (Weiss, King and Perkins 2006)(7). It should be noted, however, that researchers do not always explicitly use the term ‘personality’. For example, researchers may use terms like ‘behavioural syndromes’, ‘behavioural types’, or ‘temperament’, often not for theoretical reasons reasons but in an effort to avoid the anthropomorphic connotations of a word with ‘person’ in it.
Cross-species comparisons: One challenge facing any comparative researcher is determining the degree to which apparently similar traits really are tapping the same underlying trait. How can it be determined that what appears to be boldness in squid or trout or chimpanzees is in any way similar to boldness in humans? for example, the chimpanzee facial display in which the lips are retracted so that clenched teeth are exposed reflects fear, not happiness, as might be assumed by the expression’s apparent similarity to a human smile. To solve this challenge, cross-species researchers can draw on the lessons learned by cross-cultural researchers.

The solution to determining cross-cultural equivalence of anger expressions is examining what comes before and after the expressions, and where possible, looking for commonalities in underlying physiology. When generalizing across species, scientists must consider several dimensions of similarity and difference (Gosling 2001)(1). As a rule, researchers making cross-species comparisons should consider the species’ environmental and social ecologies, their biology, and their phylogenetic relationships with other species, and the importance of these criteria should be weighed according to what phenomenon is being examined.

Origin and function of traits: By examining the existence of traits against a backdrop of known phylogenetic relationships among species, researchers can pinpoint the likely period during which that trait emerged and can use this information to infer the original function of that trait (Fraley, Brumbaugh and Marks 2005(8); Gosling and Graybeal 2007)(9).
