Lefevre, C. E., Wilson, V. A. D., Morton, F. B., Brosnan, S. F., Paukner, A., & Bates, T. C. (2014). Facial width-to-height ratio relates to alpha status and assertive personality in capuchin monkeys. PLoS ONE, 9(4), Article e93369. https://doi.org/10.1371/journal.pone.0093369

Social dominance hierarchies play a pivotal role in shaping the behaviour of many species, and sex differences within these hierarchies often exist. To date, however, few physical markers of dominance have been identified. Such markers would be valua...

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...

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...

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).
