Title Kin-mediated reconciliation substitutes for direct reconciliation in female baboons Type Journal Article
Year 2007 Publication Proceedings. Biological sciences / The Royal Society Abbreviated Journal Proc Biol Sci
Volume 274 Issue 1613 Pages 1109-1115
Keywords
Abstract It has been hypothesized that group-living mammals engage in reconciliation (post-conflict affiliation between former opponents) to reduce the disruptive costs of aggression and restore opponents' tolerance to baseline levels. Recipients of aggression are sometimes reluctant to tolerate the proximity of a recent opponent, however, in apparent fear that aggression will be renewed. In such cases, reconciliatory behaviour by the aggressor's close kin may substitute for direct reconciliation. We describe a playback experiment with free-ranging baboons (Papio hamadryas ursinus) that examines whether friendly behaviour by the aggressor's kin can substitute for direct reconciliation by the aggressor herself. In the test condition, female subjects who had recently been threatened heard the friendly grunt of one of their aggressor's relatives, mimicking kin-mediated vocal reconciliation. In the control condition, subjects heard the grunt of a dominant female from a different matriline. Subjects responded significantly more strongly in test than in control trials. Moreover, in the next hour they were significantly more likely to tolerate the proximity of both their aggressor and the relative whose grunt they had heard. In contrast, subjects' behaviour towards both control females and other members of their aggressor's matriline was unaffected. We conclude that kin-mediated vocal reconciliation can substitute for direct reconciliation in baboons.

Title Primate social cognition and the origins of language Type Journal Article
Year 2005 Publication Trends in Cognitive Sciences Abbreviated Journal Trends. Cognit. Sci.
Volume 9 Issue 6 Pages 264-266
Keywords Animals; *Cognition; Humans; *Language; Papio; Psychological Theory; Social Behavior; *Social Perception
Abstract Are the cognitive mechanisms underlying language unique, or can similar mechanisms be found in other domains? Recent field experiments demonstrate that baboons' knowledge of their companions' social relationships is based on discrete-valued traits (identity, rank, kinship) that are combined to create a representation of social relations that is hierarchically structured, open-ended, rule-governed, and independent of sensory modality. The mechanisms underlying language might have evolved from the social knowledge of our pre-linguistic primate ancestors.

Title Recognition of other individuals' social relationships by female baboons Type Journal Article
Year 1999 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.
Volume 58 Issue 1 Pages 67-75
Keywords
Abstract We describe a series of playback experiments designed to test whether free-ranging baboons, Papio cynocephalus ursinus, recognize the calls of other group members and also associate signallers with their close genetic relatives. Pairs of unrelated females were played sequences of calls that mimicked a fight between their relatives. As controls, the same females heard sequences that involved either (1) only the more dominant female's relative or (2) neither of the females' relatives. When call sequences involved their relatives, subjects looked towards the speaker for a longer duration than when the sequences involved nonkin. When the sequences involved the other female's relative, they also looked towards that female. Subjects did not look towards one another when call sequences involved nonkin. Dominant subjects were more likely to supplant their subordinate partners following playbacks of sequences that mimicked a dispute between their relatives than following the two control trials. In contrast, both subjects were more likely to approach one another and to interact in a friendly manner following the two control trials than following the test trial. Results indicate that female baboons recognize the screams and threat grunts not only of their own close relatives but also of unrelated individuals. They also replicate previous studies in suggesting that female monkeys recognize the close associates of other individuals and adjust their interactions with others according to recent events involving individuals other than themselves.

Title Reconciliatory grunts by dominant female baboons influence victims' behaviour Type Journal Article
Year 1997 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.
Volume 54 Issue 2 Pages 409-418
Keywords
Abstract Following aggressive interactions, dominant female baboons, Papio cynocephalus ursinusoccasionally grunt to their victims. To examine the effect of these apparently reconciliatory grunts on victims' subsequent behaviour, a series of playback experiments was designed to mimic reconciliation. Victims were played their opponents' grunts in the minutes immediately following a fight and then observed for half an hour. After hearing these grunts, victims approached their former opponents and also tolerated their opponents' approaches at significantly higher rates than they did under control conditions. They were also supplanted by their opponents at significantly lower rates. By contrast, playbacks of control females' grunts did not influence victims' behaviour. Playbacks of reconciliatory grunts did not increase the rate at which opponents approached or initiated friendly interactions with their former victims. Playbacks of reconciliatory grunts, therefore, appeared to influence victims', but not opponents', perception of recent events.

Title The responses of female baboons (Papio cynocephalus ursinus) to anomalous social interactions: evidence for causal reasoning? Type Journal Article
Year 1995 Publication Journal of comparative psychology (Washington, D.C. : 1983) Abbreviated Journal J Comp Psychol
Volume 109 Issue 2 Pages 134-141
Keywords Animals; Attention; Auditory Perception; *Awareness; *Concept Formation; *Dominance-Subordination; Fear; Female; Hierarchy, Social; Papio/*psychology; *Social Behavior; Social Environment; Vocalization, Animal
Abstract Baboons' (Papio cynocephalus ursinus) understanding of cause-effect relations in the context of social interactions was examined through use of a playback experiment. Under natural conditions, dominant female baboons often grunt to more subordinate mothers when interacting with their infants. Mothers occasionally respond to these grunts by uttering submissive fear barks. Subjects were played causally inconsistent call sequences in which a lower ranking female apparently grunted to a higher ranking female, and the higher ranking female apparently responded with fear barks. As a control, subjects heard a sequence made causally consistent by the inclusion of grunts from a 3rd female that was dominant to both of the others. Subjects responded significantly more strongly to the causally inconsistent sequences, suggesting that they recognized the factors that cause 1 individual to give submissive vocalizations to another.

Title Social relationships and social cognition in nonhuman primates Type Journal Article

Keywords Animals; *Cognition; Female; Male; Pair Bond; Primates/*physiology; *Social Behavior; Social Dominance; Social Perception
Abstract Complex social relationships among nonhuman primates appear to contribute to individual reproductive success. Experiments with and behavioral observations of natural populations suggest that sophisticated cognitive mechanisms may underlie primate social relationships. Similar capacities are usually less apparent in the nonsocial realm, supporting the view that at least some aspects of primate intelligence evolved to solve the challenges of interacting with conspecifics.

Title Monkey responses to three different alarm calls: evidence of predator classification and semantic communication Type Journal Article
Year 1980 Publication Science (New York, N.Y.) Abbreviated Journal Science
Volume 210 Issue 4471 Pages 801-803
Keywords *Animal Communication; Animals; Behavior, Animal/*physiology; Cercopithecidae/*physiology; *Fear; Female; Male; Predatory Behavior; Vocalization, Animal
Abstract Vervet monkeys give different alarm calls to different predators. Recordings of the alarms played back when predators were absent caused the monkeys to run into trees for leopard alarms, look up for eagle alarms, and look down for snake alarms. Adults call primarily to leopards, martial eagles, and pythons, but infants give leopard alarms to various mammals, eagle alarms to many birds, and snake alarms to various snakelike objects. Predator classification improves with age and experience.

Title Social complexity and the information acquired during eavesdropping by primates and other animals Type Book Chapter
Year 2004 Publication Animal Communication networks Abbreviated Journal
Volume Issue Pages
Keywords
Abstract In many of the studies reviewed in this book, eavesdropping takes the

following form: a subject has the opportunity to monitor, or eavesdrop upon, an

interaction between two other animals,Aand B. The subject then uses the information

obtained through these observations to assess A`s and B`s relative dominance

or attractiveness as a mate (e.g. Mennill et al., 2002; Ch. 2). For example, Oliveira

et al. (1998) found that male fighting fish Betta splendens that had witnessed two

other males involved in an aggressive interaction subsequently responded more

strongly to the loser of that interaction than the winner. Subjects-behaviour could

not have been influenced by any inherent differences between the two males, because

subjects responded equally strongly to the winner and the loser of competitive

interactions they had not observed. Similarly, Peake et al. (2001) presented

male great tits Parus major with the opportunity to monitor an apparent competitive

interaction between two strangers by simulating a singing contest using two

loudspeakers. The relative timing of the singing bouts (as measured by the degree

of overlap between the two songs) provided information about each “contestants”

relative status. Following the singing interaction, one of the “contestants” was

introduced into the male`s territory. Males responded significantly less strongly

to singers that had apparently just “lost” the interaction (see also McGregor &

Dabelsteen, 1996; Naguib et al., 1999; Ch. 2).

What information does an individual acquire when it eavesdrops on others?

In theory, an eavesdropper could acquire information of many different sorts:

about A, about B, about the relationship between A and B, or about the place of

A`s and B`s relationship in a larger social framework. The exact information acquired

will probably reflect the particular species social structure. For example,

songbirds like great tits live in communities in which six or seven neighbours

surround each territory-holding male. Males appear to benefit from the knowledge

that certain individuals occupy specific areas (e.g. Brooks & Falls, 1975), that

competitive interactions between two different neighbours have particular outcomes,

and that these outcomes are stable over time. We would, therefore, expect

an eavesdropping great tit not only to learn that neighbour A was dominant to

neighbour B, for example, but also to form the expectation that A was likely to

defeat B in all future encounters. More speculatively, because the outcome of territorial

interactions are often site specific (reviewed by Bradbury & Vehrencamp,

1998), we would expect eavesdropping tits to learn further that A dominates B

in some areas but B dominates A in others. In contrast, the information gained

from monitoring neighbours interactions would unlikely be sufficient to allow

the eavesdropper to rank all of its neighbours in a linear dominance hierarchy,

because not all neighbouring males would come into contact with one another.

Such information would be difficult if not impossible to acquire; it might also be

of little functional value.

In contrast, species that live in large, permanent social groups have a much

greater opportunity to monitor the social interactions of many different individuals

simultaneously. Monkey species such as baboons Papio cynocephalus, for

example, typically live in groups of 80 or more individuals, which include several

matrilineal families arranged in a stable, linear dominance rank order (Silk et al.,

1999). Offspring assume ranks similar to those of their mothers, and females maintain

close bonds with their matrilineal kin throughout their lives. Cutting across

these stable long-term relationships based on rank and kinship are more transient

bonds: for example, the temporary associations formed between unrelated

females whose infants are of similar ages, and the “friendships” formed between

adult males and lactating females as an apparent adaptation against infanticide

(Palombit et al., 1997, 2001). In order to compete successfully within such groups, it

would seem advantageous for individuals to recognize who outranks whom, who

is closely bonded to whom, and who is likely to be allied to whom (Harcourt, 1988,

1992; Cheney & Seyfarth, 1990; see below). The ability to adopt a third party`s perspective

and discriminate among the social relationships that exist among others

would seem to be of great selective benefit.

In this chapter, we review evidence for eavesdropping in selected primate

species and we consider what sort of information is acquired when one individual

observes or listens in on the interactions of others. We then compare eavesdropping

by primates with eavesdropping in other animal species, focusing on both

potential differences and directions for further research
