A comparison of temperament in nonhuman apes and human infants.
(Dev Sci, 2011-11)The adaptive behavior of primates, including humans, is often mediated by temperament. Human behavior likely differs from that of other primates in part due to temperament. In the current study we compared the reaction of ... -
A fruit in the hand or two in the bush? Divergent risk preferences in chimpanzees and bonobos.
(Biol Lett, 2008-06-23)Human and non-human animals tend to avoid risky prospects. If such patterns of economic choice are adaptive, risk preferences should reflect the typical decision-making environments faced by organisms. However, this approach ... -
Chimpanzees and bonobos distinguish between risk and ambiguity.
(Biol Lett, 2011-02-23)Although recent research has investigated animal decision-making under risk, little is known about how animals choose under conditions of ambiguity when they lack information about the available alternatives. Many models ... -
Chimpanzees and bonobos exhibit divergent spatial memory development.
(Dev Sci, 2012-11)Spatial cognition and memory are critical cognitive skills underlying foraging behaviors for all primates. While the emergence of these skills has been the focus of much research on human children, little is known about ... -
Citizen Science as a New Tool in Dog Cognition Research.
(PLoS One, 2015)Family dogs and dog owners offer a potentially powerful way to conduct citizen science to answer questions about animal behavior that are difficult to answer with more conventional approaches. Here we evaluate the quality ... -
Differences in the cognitive skills of bonobos and chimpanzees.
(PLoS One, 2010-08-27)While bonobos and chimpanzees are both genetically and behaviorally very similar, they also differ in significant ways. Bonobos are more cautious and socially tolerant while chimpanzees are more dependent on extractive foraging, ... -
Differences in the early cognitive development of children and great apes.
(Dev Psychobiol, 2014-04)There is very little research comparing great ape and human cognition developmentally. In the current studies we compared a cross-sectional sample of 2- to 4-year-old human children (n=48) with a large sample of chimpanzees ... -
Direct and indirect reputation formation in nonhuman great apes (Pan paniscus, Pan troglodytes, Gorilla gorilla, Pongo pygmaeus) and human children (Homo sapiens).
(J Comp Psychol, 2013-02)Humans make decisions about when and with whom to cooperate based on their reputations. People either learn about others by direct interaction or by observing third-party interactions or gossip. An important question is ... -
Looking past the model species: diversity in gaze-following skills across primates.
(Curr Opin Neurobiol, 2009-02)Primates must navigate complex social landscapes in their daily lives: gathering information from and about others, competing with others for food and mates, and cooperating to obtain rewards as well. Gaze-following often ... -
The evolutionary origins of human patience: temporal preferences in chimpanzees, bonobos, and human adults.
(Curr Biol, 2007-10-09)To make adaptive choices, individuals must sometimes exhibit patience, forgoing immediate benefits to acquire more valuable future rewards [1-3]. Although humans account for future consequences when making temporal decisions ... -
Use of "entertainment" chimpanzees in commercials distorts public perception regarding their conservation status.
(PLoS One, 2011)Chimpanzees (Pan troglodytes) are often used in movies, commercials and print advertisements with the intention of eliciting a humorous response from audiences. The portrayal of chimpanzees in unnatural, human-like situations ...
