Personality has important links to health, social status, and life history outcomes (e.g. longevity and reproductive success). Human facial morphology appears to signal aspects of one's personality to others, raising questions about the evolutionary...

Species comparisons of personality structure (i.e., how many personality dimensions and the characteristics of those dimensions) can facilitate questions about the adaptive function of personality in nonhuman primates. Here we investigate personality...

Observational monitoring of clinical signs during the last stage of habituation in a wild Western Gorilla Group at Bai Hokou, Central African Republic (2013)
Journal Article
Morton, F. B., Todd, A. F., Lee, P., & Masi, S. (2013). Observational monitoring of clinical signs during the last stage of habituation in a wild Western Gorilla Group at Bai Hokou, Central African Republic. Folia primatologica, 84(2), 118-133. https://doi.org/10.1159/000350916

Anthropozoonotic disease transmission to great apes is a critical conservation concern, and has raised ethical doubts regarding ape habituation. We monitored over a 3-year period clinical signs within a group of wild western gorillas (G. gorilla) und...

Journal Article

In most experimental work on animal cognition, researchers attempt to control for multiple interacting variables by training subjects prior to testing, allowing subjects to participate voluntarily, and providing subjects with food rewards. However, d... Read More about Taking personality selection bias seriously in animal cognition research: A case study in capuchin monkeys (Sapajus apella).
