    • Abstract knowledge in the broken-string problem : evidence from nonhuman primates and pre-schoolers 

      Mayer, Carolina Patricia; Call, Josep; Albiach-Serrano, Anna; Visalberghi, Elisabetta; Sabbatini, Gloria; Seed, Amanda Madeleine (2014-10-01) - Journal article
      There is still large controversy about whether abstract knowledge of physical problems is uniquely human. We presented 9 capuchin monkeys, 6 bonobos, 6 chimpanzees and 48 children with two versions of a broken-string ...
    • Acquisition of a socially learned tool use sequence in chimpanzees : implications for cumulative culture 

      Vale, Gillian L.; Davis, Sarah J.; Lambeth, Susan P.; Schapiro, Steven J.; Whiten, Andrew (2017-09) - Journal article
      Cumulative culture underpins humanity's enormous success as a species. Claims that other animals are incapable of cultural ratcheting are prevalent, but are founded on just a handful of empirical studies. Whether cumulative ...
    • Acting in solidarity: testing an extended dual-pathway model of collective action by bystander group members 

      Saab, Rim; Tausch, Nicole; Spears, Russell; Cheung, Wing (2015-09) - Journal article
      We examined predictors of collective action among bystander group members in solidarity with a disadvantaged group by extending the dual pathway model of collective action, which proposes one efficacy-based and one ...
    • Active drumming experience increases infants' sensitivity to audiovisual synchrony during observed drumming actions 

      Gerson, Sarah; Schiavio, Andrea; Timmers, Renee; Hunnius, Sabine (2015-06-25) - Journal article
      In the current study, we examined the role of active experience on sensitivity to multisensory synchrony in six-month-old infants in a musical context. In the first of two experiments, we trained infants to produce a novel ...
    • Adaptation improves face trustworthiness discrimination 

      Keefe, Bruce D; Dzhelyova, Milena Petrova; Perrett, David I; Barraclough, Nick Edward (2013-06-19) - Journal article
      Adaptation to facial characteristics, such as gender and viewpoint, has been shown to both bias our perception of faces and improve facial discrimination. In this study, we examined whether adapting to two levels of face ...
    • Adaptation to facial trustworthiness is different in female and male observers 

      Wincenciak, Joanna; Dzhelyova, Milena; Perrett, David I.; Barraclough, Nick E. (2013-07-19) - Journal article
      Face adaptation paradigms have been used extensively to investigate the mechanisms underlying the processing of several different facial characteristics including face shape, identity, view and emotional expression. ...
    • Adaptive cultural transmission biases in children and nonhuman primates 

      Price, Elizabeth E.; Wood, Lara A.; Whiten, Andrew (2017-08) - Journal item
      Comparative and evolutionary developmental analyses seek to discover the similarities and differences between humans and non-human species that might illuminate both the evolutionary foundations of our nature that we share ...
    • Adaptive suicide : is a kin-selected driver of fatal behaviours likely? 

      Humphreys, Rosalind K.; Ruxton, Graeme D. (2019-02-27) - Journal item
      While several manipulated host behaviours are accepted as extended phenotypes of parasites, there remains debate over whether other altered behaviours in hosts following parasitic invasion represent cases of parasite ...
    • Adjusting foraging strategies : a comparison of rural and urban common mynas (Acridotheres tristis) 

      Federspiel, Ira G.; Garland, Alexis; Guez, David; Bugynar, Thomas; Healy, Susan D.; Güntürkün, Onur; Griffin, Andrea S. (2017-01) - Journal article
      Establishment in urbanized environments is associated with changes in physiology, behaviour, and problem-solving. We compared the speed of learning in urban and rural female common mynas, Acridotheres tristis, using a ...
    • Adverse childhood experiences and hospital-treated self-harm 

      Cleare, Seonaid; Wetherall, Karen; Clark, Andrea; Ryan, Caoimhe; Kirtley, Olivia; Smith, Michael; O’connor, Rory (2018-06-11) - Journal article
      Adverse childhood experiences (ACEs) have been implicated in a range of negative health outcomes in adulthood, including increased suicide mortality. In this study, we explored the relationship between ACEs and hospital-treated ...
    • Aesthetic and incentive salience of cute infant faces : studies of observer sex, oral contraception and menstrual cycle 

      Sprengelmeyer, Reiner; Lewis, Jennifer; Hahn, Amanda; Perrett, David I. (2013-05-29) - Journal article
      Infant cuteness can influence adult-infant interaction and has been shown to activate reward centres in the brain. In a previous study, we found men and women to be differentially sensitive to small differences in infant ...
    • African elephants (Loxodonta africana) recognize visual attention from face and body orientation 

      Smet, Ann Farai; Byrne, Richard William (2014-07-10) - Journal article
      How do animals determine when others are able and disposed to receive their communicative signals? In particular, it is futile to make a silent gesture when the intended audience cannot see it. Some non-human primates use ...
    • African elephants can use human pointing cues to find hidden food 

      Smet, Ann Farai; Byrne, Richard William (2013-10-21) - Journal article
      How animals gain information from attending to the behavior of others has been widely studied, driven partly by the importance of referential pointing in human cognitive development [1, 2, 3 and 4], but species differences ...
    • African perceptions of female attractiveness 

      Coetzee, Vinet; Faerber, Stella J; Greeff, Jaco M; Lefevre, Carmen Emilia; Re, Daniel; Perrett, David Ian (2012-10-29) - Journal article
      Little is known about mate choice preferences outside Western, educated, industrialised, rich and democratic societies, even though these Western populations may be particularly unrepresentative of human populations. To ...
    • Age-dependent cognitive inflexibility in great apes 

      Marin Manrique, Hector; Call, Josep (2015-04) - Journal article
      The ability to suppress and/or change behaviour on the basis of negative feedback, often conceptualized as cognitive flexibility, has rarely been investigated in nonhuman great apes across a broad age range. In this study, ...
    • Aggressor or protector? Experiences and perceptions of violence predict preferences for masculinity 

      Borras Guevara, Martha Lucia; Batres, Carlota; Perrett, David I. (2017-07) - Journal article
      Women’s preferences for masculine male partners have been explained in terms of heritable health. The evidence between masculinity and health, however, is controversial and therefore, alternative explanations for masculinity ...
    • Animal behaviour in a human world : a crowdsourcing study on horses that open door and gate mechanisms 

      Krueger, Konstanze; Esch, Laureen; Byrne, Richard (2019-06-26) - Journal article
      Anecdotal reports of horses opening fastened doors and gates are an intriguing way of exploring the possible scope of horses’ problem-solving capacities. The species’ natural environment has no analogues of the mechanisms ...
    • The animal origins of disgust : reports of basic disgust in nonhuman great apes 

      Case, Trevor I.; Stevenson, Richard J.; Byrne, Richard W.; Hobaiter, Catherine (2019-05-23) - Journal article
      Intrinsic to an evolved disease avoidance account of disgust is Darwin’s assumption of continuity between the emotional lives of humans and animals. However, beyond the case of avoiding stimuli that taste bad, there has ...
    • Apes have culture but may not know that they do 

      Gruber, Thibaud; Zuberbuehler, Klaus; Clement, Fabrice; van Schaik, Carel (2015-02-06) - Journal article
      There is good evidence that some ape behaviors can be transmitted socially and that this can lead to group-specific traditions. However, many consider animal traditions, including those in great apes, to be fundamentally ...
    • Apes in the Anthropocene : flexibility and survival 

      Hockings, Kimberley J.; McLennan, Matthew R.; Carvalho, Susana; Ancrenaz, Marc; Bobe, René; Byrne, R.W.; Dunbar, Robin I.M.; Matsuzawa, Tetsuro; McGrew, William C.; Williamson, Elizabeth A.; Wilson, Michael L.; Wood, Bernard; Wrangham, Richard W.; Hill, Catherine M. (2015-04) - Journal article
      We are in a new epoch, the Anthropocene, and research into our closest living relatives, the great apes, must keep pace with the rate that our species is driving change. While a goal of many studies is to understand how ...
