Abstract:
Studies of non-human primate self-recognition in mirrors demonstrate variation both within and between species. This study applied a rigorous methodology that took into account habituation of subjects to the mirror as an object and to the experimental situation. The species observed in our study was Miopithecus talapoin, which has been little studied in the wild or in captivity. Although this species shows several interesting characteristics, including complex social organisation and a high encephalization index, the talapoin monkeys in the study did not pass the mark test; however, they showed a prerequisite for self-recognition, namely comparing their body parts to the image of these in the mirror.
