    "title": "Siamangs (\nHylobates syndactylus\n) Recognize their Mirror Image",
    "subtitle": null,
    "abstract": "The ability to recognize oneself in the mirror is assumed to represent an important step towards a higher level of animal intelligence that, ultimately, can lead to human-like self-awareness and empathy. Even though rarely successful in the classical mark test, the siamang’s spontaneous behavior in front of the mirror, a visually controlled manipulation of its face, suggests that it interprets the reflection as belonging to itself. As a consequence, the cognitive status of the gibbons may need a serious reevaluation since, in total, at least three species (\nHylobates syndactylus\n, \nH.gabriellae\n, \nH. leucogenys\n) seem to be capable of self-recognition. Their, nonetheless, weak interest in the mirror image is hypothesized to be caused by the comparatively low level of sexual competition in the lesser apes.",
