  • Inter-group variation in non-conceptive sexual activity in female Japanese macaques: could it be cultural? 
    Leca, Jean-Baptiste; Gunst, Noelle; Carrier, Lydia Ottenheimer; Vasey, Paul L. (Sciknow Publications Ltd.Arts and ScienceDepartment of PsychologyUniversity of Lethbridge, 2014)
    We compared two non-conceptive sexual behavioral patterns (female-male mounting – FMM – and female-female mounting – FFM) across four free-ranging groups of Japanese macaques (Macaca fuscata) living at three different field ...
  • Behavior systems approach to object play: stone handling repertoire as a measure of propensity for complex foraging and percussive tool use in the genus Macaca 
    Pelletier, Amanda N.; Kaufmann, Tatjana; Mohak, Sidhesh; Milan, Riane; Nahallage, Charmalie A. D.; Huffman, Michael A.; Gunst, Noëlle; Rompis, Aida; Wandia, I Nengah; Arta Purta, I Gusti A.; Pellis, Sergio M.; Leca, Jean-Baptiste (SciKnow PublicationsArts and ScienceDepartment of NeuroscienceDepartment of PsychologyUniversity of LethbridgeUniversity of Sri JayewardenepuraKyoto UniversityUdayana Universityhttps://dx.doi.org/10.26451/abc.04.04.05.201, 2017)
    Stone handling (SH), has been identified in four closely related primate species of the Macaca genus. We provide the first ethogram of SH in long-tailed macaques (Macaca fascicularis), a primate species known to use stones ...
  • Is play a behavior system, and, if so, what kind? 
    Pellis, Sergio M.; Pellis, Vivien C.; Pelletier, Amanda; Leca, Jean-Baptiste (ElsevierArts and ScienceDepartment of NeuroscienceDepartment of PsychologyUniversity of Lethbridgehttps://doi.org/10.1016/j.beproc.2018.12.011, 2019)
    Given that many behavior patterns cluster together in sequences that are organized to solve specific problems (e.g., foraging), a fruitful perspective within which to study behaviors is as distinct ‘behavior systems’. ...
  • Are the roots of human economic systems shared with non-human primates? 
    Addessi, Elsa; Beran, Michael J.; Bourgeois-Gironde, Sacha; Brosnan, Sarah F.; Leca, Jean-Baptiste (ElsevierArts and ScienceDepartment of PsychologyISTC-CNRGeorgia State UniversityInstitut Jean-NicodUniversity of Lethbridgehttps://doi.org/10.1016/j.neubiorev.2019.12.026, 2020)
    We review and analyze evidence for an evolutionary rooting of human economic behaviors and organization in non-human primates. Rather than focusing on the direct application of economic models that a priori account for ...
  • Animal culture: how a birdsong went viral 
    Logue, David M.; Leca, Jean-Baptiste (Cell PressArts and ScienceDepartment of PsychologyUniversity of LethbridgeUniversity of Puerto Ricohttps://doi.org/10.1016/j.cub.2020.06.055, 2020)
    A new white-throated sparrow song has overtaken most of Canada in less than 20 years. The explanation for this remarkably fast spread may lie in the southern migratory grounds, where populations from across Canada converge ...
  • Acquisition of object-robbing and object/food-bartering behaviours: a culturally maintained token economy in free-ranging long-tailed macaques 
    Leca, Jean-Baptiste; Gunst, Noëlle; Gardiner, Matthew; Wandia, I. Nengah (The Royal Society PublishingArts and ScienceDepartment of PsychologyUniversity of LethbridgeUdayana Universityhttps://doi.org/10.1098/rstb.2019.0677, 2021)
    The token exchange paradigm shows that monkeys and great apes are able to use objects as symbolic tools to request specific food rewards. Such studies provide insights into the cognitive underpinnings of economic behaviour ...
  • Sexual adaptation: is female-male mounting a supernormal courtship display in Japanese macaques? 
    Gunst, Noëlle; Leca, Jean-Baptiste; Vasey, Paul L. (BrillArts and ScienceDepartment of Psychologyhttps://doi.org/10.1163/1568539X-bja10161, 2022)
    We analysed heterosexual consortships in a free-ranging group of Japanese macaques in which adult females routinely perform female-to-male mounting (FMM). We tested whether FMM is more efficient (i.e., a “supernormal ...
  • When males have females on their backs: male's tolerance, solicitation, and use of female-male mounting in Japanese macaques 
    Gunst, Noëlle; Leca, Jean-Baptiste; Vasey, Paul L. (WileyArts and ScienceDepartment of PsychologyUniversity of Lethbridgehttps://doi.org/10.1002/ajp.23395, 2022)
    Previous research on Japanese macaques has shown that female-to-male mounting (FMM) is performed by some females as an exaggerated form of sexual solicitation that may occur in the context of high female competition for ...
  • Two types of withdraw-to-eat movement related to food size in long-tailed macaques (Macaca fascicularis): insights into the evolution of the visual control of hand shaping in anthropoid primates 
    Hirsche, Laurie A.; Cenni, Camilla; Leca, Jean-Baptiste; Whishaw, Ian (Sciknow PublicationsArts and ScienceDepartment of NeuroscienceDepartment of PsychologyUniversity of LethbridgeNational Institute of Advanced Studies (Bangalore, India)https://doi.org/10.26451/abc.09.02.02.2022, 2022)
    The details of the evolutionary steps in the transition from nonvisual guidance of hand movements for feeding, as displayed by many non-primate species, to visual guidance of hand movements in primates are sparse. Contemporary ...
  • Do monkeys use sex toys? Evidence of stone tool-assisted masturbation in free-ranging long-tailed macaques 
    Cenni, Camilla; Christie, Jessica B. A.; Van der Pant, Yanni; Gunst, Noëlle; Vasey, Paul L.; Wandia, Nengah; Leca, Jean-Baptiste (Wileyhttps://doi.org/10.1111/eth.13324, 2022)
    Recent reports on tool use in nonforaging contexts have led researchers to reconsider the proximate drivers of instrumental object manipulation. In this study, we explore the physiological and behavioral correlates of ...
