      Signalling plays an important role in facilitating and maintaining affiliative or cooperative interactions in social animals. Social grooming in primates is an example of an interaction that requires coordination between ...
    • Coevolution of cultural intelligence, extended life history, sociality, and brain size in primates 

      Street, Sally E.; Navarrete, Ana F.; Reader, Simon M.; Laland, Kevin N. (2017-07-25) - Journal article
      Explanations for primate brain expansion and the evolution of human cognition and culture remain contentious despite extensive research. While multiple comparative analyses have investigated variation in brain size across ...
    • Distinctiveness enhances long-term event memory in non-human primates, irrespective of reinforcement 

      Lewis, Amy; Call, Josep; Berntsen, Dorthe (2017-08) - Journal article
      Non-human primates are capable of recalling events that occurred as long as three years ago, and are able to distinguish between similar events; akin to human memory. In humans, distinctiveness enhances memory for events, ...

      MacLean, Evan L; Hare, Brian; Nunn, Charles L; Addessi, Elsa; Amici, Federica; Anderson, Rindy C; Aureli, Filippo; Baker, Joseph M; Bania, Amanda E; Barnard, Allison M; Boogert, Neeltje J; Brannon, Elizabeth M; Bray, Emily E; Bray, Joel; Brent, Lauren J N; Burkart, Judith M; Call, Josep; Cantlon, Jessica F; Cheke, Lucy G; Clayton, Nicola S; Delgado, Mikel M; DiVincenti, Louis J; Fujita, Kazuo; Herrmann, Esther; Hiramatsu, Chihiro; Jacobs, Lucia F; Jordan, Kerry E; Laude, Jennifer R; Leimgruber, Kristin L; Messer, Emily J E; Moura, Antonio C de A; Ostojić, Ljerka; Picard, Alejandra; Platt, Michael L; Plotnik, Joshua M; Range, Friederike; Reader, Simon M; Reddy, Rachna B; Sandel, Aaron A; Santos, Laurie R; Schumann, Katrin; Seed, Amanda M; Sewall, Kendra B; Shaw, Rachael C; Slocombe, Katie E; Su, Yanjie; Takimoto, Ayaka; Tan, Jingzhi; Tao, Ruoting; van Schaik, Carel P; Virányi, Zsófia; Visalberghi, Elisabetta; Wade, Jordan C; Watanabe, Arii; Widness, Jane; Young, Julie K; Zentall, Thomas R; Zhao, Yini (2014-05-20) - Journal article
      Cognition presents evolutionary research with one of its greatest challenges. Cognitive evolution has been explained at the proximate level by shifts in absolute and relative brain volume and at the ultimate level by ...
    • Food-offering calls in wild golden lion tamarins (Leontopithecus rosalia) : evidence for teaching behavior? 

      Troisi, Camille Aurelie; Hoppitt, Will J.; Ruiz-Miranda, Carlos R.; Laland, Kevin Neville (2018-11-21) - Journal article
      Many animals emit calls in the presence of food, but researchers do not always know the function of these calls. Evidence suggests that adult golden lion tamarins (Leontopithecus rosalia) use food-offering calls to teach ...
    • The interplay of prior experience and motivation in great ape problem-solving (Gorilla gorilla, Pan paniscus, Pan troglodytes, and Pongo abelii) 

      Ebel, Sonja Jördis; Call, Josep (2018-08) - Journal article
      Many primate species have a strong disposition to approach and manipulate objects in captivity. However, few studies have investigated what primates learn during free exploration of objects in the absence of rewards, and ...
    • Lack of prosociality in great apes, capuchin monkeys and spider monkeys : convergent evidence from two different food distribution tasks 

      Amici, Federica; Visalberghi, Elisabetta; Call, Josep (2014-10-22) - Journal article
      Prosociality can be defined as any behaviour performed to alleviate the needs of others or to improve their welfare. Prosociality has probably played an essential role in the evolution of cooperative behaviour and several ...
    • Monkeys (Sapajus apella and Macaca tonkeana) and great apes (Gorilla gorilla, Pongo pygmaeus, Pongo abelii, Pan paniscus and Pan troglodytes) play for the highest bid 

      Broihanne, M. -H.; Romain, A.; Call, Josep; Thierry, B.; Wascher, C. A. F.; De Marco, A.; Verrier, D.; Dufour, V. (2018-12-27) - Journal article
      Many studies investigate the decisions made by animals by focussing on their individual attitudes towards risk, i.e., risk seeking, risk neutrality or risk aversion. However, little attention has been paid to how far ...
    • Multi-modal use of a socially directed call in Bonobos 

      Genty, Emilie Juliette Pauline; Clay, Zanna; Hobaiter, Cat; Zuberbuehler, Klaus (2014-01-15) - Journal article
      ‘Contest hoots’ are acoustically complex vocalisations produced by adult and subadult male bonobos (Pan paniscus). These calls are often directed at specific individuals and regularly combined with gestures and other body ...
    • Primate brain anatomy : new volumetric MRI measurements for neuroanatomical studies 

      Navarrete, Ana F.; Blezer, Erwin L.A.; Pagnotta, Murillo; de Viet, Elizabeth S.M.; Todorov, Orlin S.; Lindenfors, Patrik; Laland, Kevin N.; Reader, Simon M. (2018-07) - Journal article
      Since the publication of the primate brain volumetric dataset of Stephan and colleagues in the early 1980s, no major new comparative datasets covering multiple brain regions and a large number of primate species have become ...
    • The psychology of primate cooperation and competition : a call for realigning research agendas 

      Schmelz, Martin; Call, Josep (2016-01-19) - Journal article
      Cooperation and competition are two key components of social life. Current research agendas investigating the psychological underpinnings of competition and cooperation in non-human primates are misaligned. The majority ...

      Whiten, Andrew; van de Waal, Erica (2017-11) - Journal item
      Noting important recent discoveries, we review primate social learning, traditions and culture, together with associated findings about primate brains. We survey our current knowledge of primate cultures in the wild, and ...
