Exploring the behavioral reactions to a mirror in the nocturnal grey mouse lemur: sex differences in avoidance.

Most mirror-image stimulation studies (MIS) have been conducted on social and diurnal animals in order to explore self-recognition, social responses, and personality traits. Small, nocturnal mammals are difficult to study in the wild and are under-represented in experimental behavioral studies. In this pilot study, we explored the behavioral reaction of a small nocturnal solitary forager-the grey mouse lemur (-an emergent animal model in captivity.
