“…This does not necessarily point to superior cognitive abilities but can be explained by priority of access to learning opportunities. That high-ranking animals learn first, because they have priority of access to the apparatus, has been observed before in experiments in which group-living animals had to solve technical problems (e.g., [28][29][30]). The accomplishment of our vervets has a different quality, however: They had to motivate a conspecific from a distance to perform the behavior they desired, as opposed to handling an apparatus at close range, and they could never be sure that their personal activities alone caused a specific reaction of the provider.…”

Vervet Monkeys Solve a Multiplayer “Forbidden Circle Game” by Queuing to Learn Restraint

In social dilemmas, the ability of individuals to coordinate their actions is crucial to reach group optima. Unless exacted by power or force, coordination in humans relies on a common understanding of the problem, which is greatly facilitated by communication. The lack of means of consultation about the nature of the problem and how to solve it may explain why multiagent coordination in nonhuman vertebrates has commonly been observed only when multiple individuals react instantaneously to a single stimulus, either natural or experimentally simulated, for example a predator, a prey, or a neighboring group. Here we report how vervet monkeys solved an experimentally induced coordination problem. In each of three groups, we trained a low-ranking female, the "provider," to open a container holding a large amount of food, which the providers only opened when all individuals dominant to them ("dominants") stayed outside an imaginary "forbidden circle" around it. Without any human guidance, the dominants learned restraint one by one, in hierarchical order from high to low. Once all dominants showed restraint immediately at the start of the trial, the providers opened the container almost instantly, saving all individuals opportunity costs due to lost foraging time. Solving this game required trial-and-error learning based on individual feedback from the provider to each dominant, and all dominants being patient enough to wait outside the circle while others learned restraint. Communication, social learning, and policing by high-ranking animals played no perceptible role.

“…Although play does persist into adolescence and adulthood, it may occur at lower rates in adults as compared to younger animals [Goodall, 1986]. In a study of Guinea baboons, Lepoivre and Pallaud [1985] found that individuals with strong affiliative relationships were more likely to exhibit social facilitation. In humans, power relationships play a role in the occurrence of emotional contagion in a way that might not be expected: individuals in a position of power are more likely to display emotional contagion from a subordinate's feelings than vice versa [Hsee et al, 1990].…”

Previous studies of captive chimpanzees have demonstrated the "neighbor effect," or social contagion, with respect to agonistic vocalizations and behaviors. The present study considers whether there is a relationship between behavior patterns in focal animals and the auditory signals of neighboring social groups. Using focal-group sampling, we collected 172.5 hr of data on 51 subjects (25 females and 26 males) housed in 10 social groups. We performed two-tailed Wilcoxon matched-pairs signed-rank tests to determine whether the relative frequency of the vocalizations (high vs. low) affected the behaviors. In keeping with past research, we found that agonistic noises and vocalizations from neighboring social groups had a significant effect on the rates of focal-group bluff displays, pant-hoots, and aggression (P<0.05). In addition, we also found significant relationships between grooming behavior and vocalizations in focal groups, and grooming vocalizations from neighboring groups (P<0.05). The results suggest that social contagion is not limited to aggressive behaviors, but also occurs for affiliative behavior patterns.

“…Social interactions are typically viewed as enabling information exchange or enhancing problem-solving behavior, but they can also be inhibitory, as evidenced by the social facilitation of errors (Lepoivre & Pallaud, 1985). In addition, a complex setting contains a diversity of cues that may compete for an animal's attention, with negative consequences on performance.…”

To assess the relation between performance and social or demographic variables, this study group tested a captive monkey colony on visual and manual discrimination problems. Animals could choose between differently colored, sand-filled boxes, where hue signaled the initial probability of finding buried food items. Dominant animals and subadults were most successful in locating and retrieving incentives, but sex did not affect performance. Rank effects occurred without overt aggression, suggesting deference by subordinates as a mediating mechanism. Age effects may reflect changing attention patterns only evident in complex arenas where cue salience becomes diluted. Because these findings differ from studies of singly tested animals, they show that, in a social context, an individual's rank and age may define opportunities to gain or efficiently use information.
