Object individuation using property/kind information in rhesus macaques (Macaca mulatta)Laurie R Santos
Department of Psychology, Harvard University, William James Hall, 33 Kirkland Street, Cambridge, MA 02138, USA
Cognition 83:241-64. 2002....- Expectations about numerical events in four lemur species (Eulemur fulvus, Eulemur mongoz, Lemur catta and Varecia rubra)Laurie R Santos
Department of Psychology, Yale University, New Haven, CT 06520, USA
Anim Cogn 8:253-62. 2005..These results suggest that some prosimian primates understand the outcome of simple arithmetic operations. These results are discussed in light of similar findings in human infants and other adult primates... 
Comparative cognition: united we standLaurie R Santos
Department of Psychology, Yale University, Box 208205, New Haven, CT 06510, USA
Curr Biol 21:R951-3. 2011..Humans engage in collaborative activities far more often than do members of any other species. Two recent studies explore why this is the case. Are humans uniquely motivated to work together?..- Probing the limits of tool competence: experiments with two non-tool-using species (Cercopithecus aethiops and Saguinus oedipus)Laurie R Santos
Department of Psychology, Yale University, Box 208205, New Haven, CT, USA
Anim Cogn 9:94-109. 2006..These results provide further evidence that tool-use may derive from domain-general, rather than domain-specific cognitive capacities that evolved for tool use per se... - How prosimian primates represent tools: experiments with two lemur species (Eulemur fulvus and Lemur catta)Laurie R Santos
Department of Psychology, Yale University, New Haven, CT 06520, USA
J Comp Psychol 119:394-403. 2005..Subjects performed well on these problems, sometimes modifying the position of the tool. These results are discussed in light of the performance of other primates on this task... - Primate cognition: putting two and two togetherLaurie R Santos
Yale University, Department of Psychology, New Haven, CT 06510, USA
Curr Biol 15:R545-7. 2005..The human mind has the capacity for abstract numerical representations that cut across different sensory modalities. New research with monkeys shows that this mathematical achievement is not unique to our species... - Economic cognition in humans and animals: the search for core mechanismsLaurie R Santos
Department of Psychology, Yale University, New Haven, CT 06510, USA
Curr Opin Neurobiol 19:63-6. 2009.... - Means-means-end tool choice in cotton-top tamarins (Saguinus oedipus): finding the limits on primates' knowledge of toolsLaurie R Santos
Department of Psychology, Yale University, New Haven, CT, USA
Anim Cogn 8:236-46. 2005..Subjects readily transferred to new connections. Our results therefore provide the first evidence to date that tamarins can learn to solve problems involving two tools, but that they do so only with sufficient training... - 'Core knowledges': a dissociation between spatiotemporal knowledge and contact-mechanics in a non-human primate?Laurie R Santos
Department of Psychology, Harvard University, USA
Dev Sci 7:167-74. 2004..This dissociation between contact-mechanical and spatiotemporal knowledge is discussed in light of developmental theories of core knowledge and the literature on object-based attention in human adults... - Representing tools: how two non-human primate species distinguish between the functionally relevant and irrelevant features of a toolLaurie R Santos
Department of Psychology, Harvard University, Cambridge, MA 02138, USA
Anim Cogn 6:269-81. 2003..We propose that some non-human primates begin with a predisposition to attend to a tool's shape and, with sufficient experience, develop a more sophisticated understanding of the features that are functionally relevant to tools... - Enumeration of objects and substances in non-human primates: experiments with brown lemurs (Eulemur fulvus)Neha Mahajan
Department of Psychology, Yale University, New Haven, CT, USA
Dev Sci 12:920-8. 2009..In contrast to human infants, however, lemurs successfully enumerated non-cohesive objects that broke into multiple pieces. These results are discussed in light of recent theories about object processing in human infants and adults... - 'Unwilling' versus 'unable': capuchin monkeys' (Cebus apella) understanding of human intentional actionWebb Phillips
Department of Psychology, Yale University, USA
Dev Sci 12:938-45. 2009..Taken together with the previous evidence, the present research suggests that our own intention reading is not a wholly unique aspect of the human species, but rather is shared broadly across the primate order... - Dynamic object individuation in rhesus macaques: a study of the tunnel effectJonathan I Flombaum
Department of Psychology, Yale University, New Haven, CT 06520, USA
Psychol Sci 15:795-800. 2004..With further control conditions, this experiment demonstrates a spatiotemporal bias-similar to a bias found in adult visual perception-in the computation of object persistence in the context of a dynamic correspondence problem... - Essentialism in the absence of language? Evidence from rhesus monkeys (Macaca mulatta)Webb Phillips
Department of Psychology, Yale University, USA
Dev Sci 13:F1-7. 2010..These results therefore suggest that some essentialist expectations may emerge in the absence of language, and thus raise the possibility that such tendencies may emerge earlier in human development than has previously been considered... 
Reflections of other minds: how primate social cognition can inform the function of mirror neuronsDerek E Lyons
Yale University, Department of Psychology, PO Box 208205, New Haven, Connecticut 06520 8205, USA
Curr Opin Neurobiol 16:230-4. 2006..We are thus left with a fascinating question: if not imitation, what are mirror neurons for? Recent advances in the study of non-human primate social cognition suggest a surprising potential answer...- Young children are more generous when others are aware of their actionsKristin L Leimgruber
Department of Psychology, Yale University, New Haven, Connecticut, United States of America
PLoS ONE 7:e48292. 2012.... - Units of visual individuation in rhesus macaques: objects or unbound features?Erik W Cheries
Department of Psychology, Yale University, New Haven, CT 06520 8205, USA
Perception 35:1057-71. 2006..This pattern of results demonstrates that feature binding is used in subtle ways to guide ecologically relevant behavior in a non-human animal, spontaneously and reliably, in its natural environment... - Endowment effect in capuchin monkeysVenkat Lakshminaryanan
Department of Psychology, Yale University, New Haven, CT 06520, USA
Philos Trans R Soc Lond B Biol Sci 363:3837-44. 2008.... - The evolution of intergroup bias: perceptions and attitudes in rhesus macaquesNeha Mahajan
Department of Psychology, Yale University, New Haven, CT 06520, USA
J Pers Soc Psychol 100:387-405. 2011..As such, these studies suggest that the architecture of the mind that enables the formation of these biases may be rooted in phylogenetically ancient mechanisms... - How capuchin monkeys (Cebus apella) quantify objects and substancesKristy VanMarle
Department of Psychology, Yale University, New Haven, CT, USA
J Comp Psychol 120:416-26. 2006..This finding suggests that capuchins quantify objects and substances similarly and do so via analog magnitude representations... - Monkeys represent others' knowledge but not their beliefsDrew C W Marticorena
Department of Psychology, Yale University, New Haven, CT 06520, USA

Department of Psychology, Yale University, New Haven, CT 06520, USA
Curr Biol 15:447-52. 2005..Moreover, they raise the possibility that, in primates, cortical cells thought to encode where others are looking [7] may encode what those individuals see as well... - Evidence for kind representations in the absence of language: experiments with rhesus monkeys (Macaca mulatta)Webb Phillips
Department of Psychology, Yale University, USA
Cognition 102:455-63. 2007..Although these data provide the best evidence to date that language is not necessary to represent kinds, we discuss our findings in terms of possible associative hypotheses as well... - The origins of cognitive dissonance: evidence from children and monkeysLouisa C Egan
Department of Psychology, Yale University, New Haven, CT 06520, USA
Psychol Sci 18:978-83. 2007..They suggest that the mechanisms underlying cognitive-dissonance reduction in human adults may have originated both developmentally and evolutionarily earlier than previously thought... - Helping behaviour and regard for others in capuchin monkeys (Cebus apella)Jennifer L Barnes
