No Response to Inconsistently Experienced Inequity in Four Primate Species
Understanding when and how nonhuman primates respond to inequity is essential for uncovering the evolutionary roots of human fairness. Previous studies have shown that some species will refuse to participate or refuse rewards in some contexts when outcomes are unequal, but in these studies, subjects experienced inequity on every trial. This is likely not a realistic reflection of daily life, and we do not know whether these responses persist when…
Playbacks of food-associated calls attract chimpanzees towards known food patches in a captive setting
Why do chimpanzees have diverse behavioral repertoires yet lack more complex cultures? Invention and social information use in a cumulative task
Validation and utility of a body condition scoring system for chimpanzees ( Pan troglodytes )
Obesity is a problem in captive chimpanzee colonies that can lead to increased risk for disease; therefore, implementation of effective weight management strategies is imperative. To properly implement a weight management program, captive managers should be able to noninvasively identify and assess overweight or obese individuals. Traditional means of categorizing obese individuals involve sedating the animals to obtain body weights or skin fold …
The implementation and initial evaluation of a physical therapy program for captive chimpanzees ( Pan troglodytes )
Due to advances in captive nonhuman primate (NHP) medical care, the number of geriatric chimpanzees (≥35‐years old) is growing. With old age comes a variety of physical conditions, including arthritis, stroke, and mobility impairments. Programs aimed at enhancing the welfare of geriatric chimpanzees are now quite common, but there are few published empirical evaluations of the efficacy of such programs. The current study aimed to create, implemen…
Unpacking chimpanzee ( Pan troglodytes ) patch use
The marginal value theorem is an optimal foraging model that predicts how efficient foragers should respond to both their ecological and social environments when foraging in food patches, and it has strongly influenced hypotheses for primate behavior. Nevertheless, experimental tests of the marginal value theorem have been rare in primates and observational studies have provided conflicting support. As a step towards filling this gap, we test whe…
Sex differences in longitudinal personality stability in chimpanzees
Acquisition of a socially learned tool use sequence in chimpanzees
Socially transmitted diffusion of a novel behavior from subordinate chimpanzees
Chimpanzees (Pan troglodytes) demonstrate much cultural diversity in the wild, yet a majority of novel behaviors do not become group-wide traditions. Since many such novel behaviors are introduced by low-ranking individuals, a bias toward copying dominant individuals ("rank-bias") has been proposed as an explanation for their limited diffusion. Previous experimental work showed that chimpanzees (Pan troglodytes) preferentially copy dominant over …
Chimpanzees copy dominant and knowledgeable individuals
Developing a comprehensive and comparative questionnaire for measuring personality in chimpanzees using a simultaneous top‐down/bottom‐up design
One effective method for measuring personality in primates is to use personality trait ratings to distill the experience of people familiar with the individual animals. Previous rating instruments were created using either top-down or bottom-up approaches. Top-down approaches, which essentially adapt instruments originally designed for use with another species, can unfortunately lead to the inclusion of traits irrelevant to chimpanzees or fail to…
Evolution and the expression of biases
Cognitive and behavioral biases, which are widespread among humans, have recently been demonstrated in other primates, suggesting a common origin. Here we examine whether the expression of one shared bias, the endowment effect, varies as a function of context. We tested whether objects lacking inherent value elicited a stronger endowment effect (or preference for keeping the object) in a context in which the objects had immediate instrumental val…
An Evaluation of the Efficacy of Video Displays for Use With Chimpanzees ( P an troglodytes )
Video displays for behavioral research lend themselves particularly well to studies with chimpanzees ( P an troglodytes ), as their vision is comparable to humans’, yet there has been no formal test of the efficacy of video displays as a form of social information for chimpanzees. To address this, we compared the learning success of chimpanzees shown video footage of a conspecific compared to chimpanzees shown a live conspecific performing the sa…
Male chimpanzees' grooming rates vary by female age, parity, and fertility status
Copulation preferences in our closest living relative, the chimpanzee, suggest that males prefer older females who have had previous offspring. However, this finding is counter to some behavioral models, which predict that chimpanzee males, as promiscuous breeders with minimal costs to mating, should show little or no preference when choosing mating partners (e.g. should mate indiscriminately). To determine if the preferences indicated by copulat…
Bipedal tool use strengthens chimpanzee hand preferences
Positive reinforcement training affects hematologic and serum chemistry values in captive chimpanzees ( Pan troglodytes )
Positive reinforcement training (PRT) techniques have received considerable attention for their stress reduction potential in the behavioral management of captive nonhuman primates. However, few published empirical studies have provided physiological data to support this position. To address this issue, PRT techniques were used to train chimpanzees ( Pan troglodytes ) to voluntarily present a leg for an intramuscular (IM) injection of anesthetic.…
