Capuchin monkeys judge third-party reciprocity
Cognition, 2013Increasing interest is being shown in how children develop an understanding of reciprocity in social exchanges and fairness in resource distribution, including social exchanges between third parties. Although there are descriptions of reciprocity on a one-to-one basis in other species, whether nonhumans detect reciprocity and violations of reciprocity ...

Food-exchange with humans in brown capuchin monkeys
Primates, 2005To assess how brown capuchin monkeys (Cebus apella) delay gratification and maximize payoff, we carried out four experiments in which six subjects could exchange food pieces with a human experimenter. The pieces differed either in quality or quantity. In qualitative exchanges, all subjects gave a piece of food to receive another of higher value.

Working memory in capuchin monkeys (Cebus apella)
Behavioural Brain Research, 2002It has been suggested that delayed (non-) matching to sample (DNMTS/DMTS) tasks using trial-unique stimuli and short, as well as longer delay intervals, can provide important insights into animal cognition. Therefore, this research examined the capability of the New World capuchin monkey (Cebus apella) in perform trial-unique DMTS and DNMTS tasks ...

Resistance of capuchin monkeys to reinfection with Schistosoma haematobium
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1988Capuchin monkeys were resistant to reinfection with Schistosoma haematobium one year after exposure to 500 cercariae, but worms in these monkeys continued to produce normal numbers of eggs. Monkeys were apparently completely refractory to reinfection when challenged 2-5 years after an initial exposure of 1000 to 2000 cercariae.

Handedness and cortisol in tufted capuchin monkey infants
Developmental Psychobiology, 2000In this research, we examined the relationship between handedness and levels of plasma cortisol in infant monkeys (Cebus apella). Specifically, we sought to test the hypothesis that stress functioning is related to hemispheric specialization and is manifested in a positive correlation between cortisol levels and the frequency of right- versus left-hand

Capuchin monkey research priorities and urgent issues
American Journal of Primatology, 2014The “Capuchin research community roundtable: working together towards a comparative biology of Cebus and Sapajus” was held at the International Primatological Society Congress in Cancún, Mexico, August 2012. Goals of the roundtable were to strengthen interactions among the capuchin research community, and to prioritize and coordinate research and ...

Suppression of ovulation by a synthetic progestin in the capuchin monkey
Journal of Medical Primatology, 2009AbstractBackground From the limited research in New World monkeys it is not clear whether they are as sensitive to the antiovulatory effects of synthetic progestins as noted in human beings. We examined whether levonorgestrel prevented ovulation in the capuchin monkey.Methods Cebus apella monkeys were treated orally with two doses of 2 mg of ...

Capuchin monkeys are not prosocial in an instrumental helping task
Animal Cognition, 2011Comparative research can shed light on the evolutionary roots and cognitive underpinnings of prosocial behavior by revealing not only positive instances of prosocial motivations in other species, but also the boundary conditions of these motivations. To explore factors that may constrain prosocial behavior, we examined whether brown capuchins (Cebus ...
