“…A few studies have demonstrated picture equivalence in chimpanzees (36,39) and capuchins (40), but for other nonhuman primates, results may fall under confusion (41,42). If capuchin monkeys in the present study demonstrate differentiation between facial images of in-group and out-group conspecifics, as they do in real life (43)(44)(45)(46), and fail to show confusion (e.g., hostile reactions to out-group members), we may conclude that this species interprets two-dimensional images as representing reality.…”

Nonhuman primates posses a highly developed capacity for face recognition, which resembles the human capacity both cognitively and neurologically. Face recognition is typically tested by having subjects compare facial images, whereas there has been virtually no attention to how they connect these images to reality. Can nonhuman primates recognize familiar individuals in photographs? Such facial identification was examined in brown or tufted capuchin monkeys (Cebus apella), a New World primate, by letting subjects categorize facial images of conspecifics as either belonging to the in-group or out-group. After training on an oddity task with four images on a touch screen, subjects correctly identified one in-group member as odd among three out-group members, and vice versa. They generalized this knowledge to both new images of the same individuals and images of juveniles never presented before, thus suggesting facial identification based on real-life experience with the depicted individuals. This ability was unexplained by potential color cues because the same results were obtained with grayscale images. These tests demonstrate that capuchin monkeys, like humans, recognize whom they see in a picture.face recognition ͉ individual discrimination ͉ oddity ͉ primate ͉ visual discrimination

“…Capuchins live in social groups of Ϸ14-17 individuals and regularly come into both visual and physical contact with neighboring groups (43,47). Both in captivity and in the wild, capuchin monkeys typically are hostile to outsiders (43)(44)(45)(46). We do not know, however, what information they use to discriminate between in-group and out-group members.…”

“…Like most nonhuman primates, capuchin monkeys are hostile toward out-group members in the wild (29,30) and in captivity (36)(37)(38), even though intergroup hostility tends to be limited to the adult males and alpha female in brown capuchins (30). In the present study, we speak of out-group pairs rather than strangers because although members of different groups lack visual contact, they do have auditory contact and had seen each other a couple of times during two past experiments (9,37).…”

The debate about the origins of human prosociality has focused on the presence or absence of similar tendencies in other species, and, recently, attention has turned to the underlying mechanisms. We investigated whether direct reciprocity could promote prosocial behavior in brown capuchin monkeys (Cebus apella). Twelve capuchins tested in pairs could choose between two tokens, with one being "prosocial" in that it rewarded both individuals (i.e., 1/1), and the other being "selfish" in that it rewarded the chooser only (i.e., 1/0). Each monkey's choices with a familiar partner from their own group was compared with choices when paired with a partner from a different group. Capuchins were spontaneously prosocial, selecting the prosocial option at the same rate regardless of whether they were paired with an in-group or out-group partner. This indicates that interaction outside of the experimental setting played no role. When the paradigm was changed, such that both partners alternated making choices, prosocial preference significantly increased, leading to mutualistic payoffs. As no contingency could be detected between an individual's choice and their partner's previous choice, and choices occurred in rapid succession, reciprocity seemed of a relatively vague nature akin to mutualism. Having the partner receive a better reward than the chooser (i.e., 1/2) during the alternating condition increased the payoffs of mutual prosociality, and prosocial choice increased accordingly. The outcome of several controls made it hard to explain these results on the basis of reward distribution or learned preferences, and rather suggested that joint action promotes prosociality, resulting in so-called attitudinal reciprocity.cooperation | tit-for-tat | inequity | mirroring

“…A l'exception des procedures decrites par Fragaszy et al (1994), les methodes employees mettent l'accent sur l'importance d'une introduction progressive, ä savoir, une exposition graduelle du nouveau-venu avec chaque membre du groupe etabli. Selon Fragaszy et al (1994), les reactions des membres d'un groupe a l'arrivee d'un etranger sont plus moderees chez les singes capucins que chez les singes de 1'Ancien Monde. Ces auteurs concluent en particulier que 1'introduction d'une nouvelle femelle adulte dans un groupe contenant dejä un male adulte est possible, mais des risques degression serieuse subsistent.…”
