  • 3D camouflage : exploiting photons to conceal form 

    Penacchio, Olivier; Lovell, Paul George; Cuthill, Innes; Ruxton, Graeme Douglas; Harris, Julie (2015-10) - Journal article
    Many animals have a gradation of body color, termed countershading, where the areas that are typically exposed to more light are darker. One hypothesis is that this patterning enhances visual camouflage by making the retinal ...
  • Able-bodied wild chimpanzees imitate a motor procedure used by a disabled individual to overcome handicap 

    Hobaiter, Catherine; Byrne, Richard William (2010-08-05) - Journal article
    Chimpanzee culture has generated intense recent interest, fueled by the technical complexity of chimpanzee tool-using traditions; yet it is seriously doubted whether chimpanzees are able to learn motor procedures by imitation ...
  • Abnormal center-periphery gradient in spatial attention in simultanagnosia 

    Balslev, Daniela; Odoj, Bartholomaeus; Rennig, Johannes; Karnath, Hans-Otto (2014-06-04) - Journal article
    Patients suffering from simultanagnosia cannot perceive more than one object at a time. The underlying mechanism is incompletely understood. One hypothesis is that simultanagnosia reflects "tunnel vision," a constricted ...
  • 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 ...
  • Acoustic models of orangutan hand-assisted alarm calls 

    De Boer, Bart; Wich, Serge A.; Hardus, Madeleine E.; Lameira, Adriano R. (2015-03-18) - Journal article
    Orangutans produce alarm calls called kiss-squeaks, which they sometimes modify by putting a hand in front of their mouth. Through theoretical models and observational evidence, we show that using the hand when making a ...
  • 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. ...
  • Adapting to time : duration channels do not mediate human time perception 

    Curran, WIlliam; Benton, Christopher; Harris, Julie; Hibbard, Paul Barry; Beattie, L (2016-03) - Journal article
    Accurately encoding the duration and temporal order of events is essential for survival and important to everyday activities, from holding conversations to driving in fast-flowing traffic. Although there is a growing body ...
  • 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 ...
  • Adding a psychological dimension to mass gatherings medicine 

    Hopkins, Nick; Reicher, Stephen (2016-06) - Journal article
    Objectives. Mass gatherings pose distinctive challenges for medicine. One neglected aspect of this is that the behaviour of people participating in such events is different from the behaviour they exhibit in their everyday ...
  • Adenosine-mediated modulation of ventral horn interneurons and spinal motoneurons in neonatal mice 

    Witts, Emily Charlotte; Nascimento, Filipe; Miles, Gareth Brian (2015-10) - Journal article
    Neuromodulation allows neural networks to adapt to varying environmental and biomechanical demands. Purinergic signalling is known to be an important modulatory system in many parts of the CNS, including motor control ...
  • ‘Adoption’ by maternal siblings in wild chimpanzees 

    Hobaiter, Cat; Schel, Anne Marijke; Langergraber, Kevin; Zuberbuehler, Klaus (2014-08-01) - Journal article
    The adoption of unrelated orphaned infants is something chimpanzees and humans have in common. Providing parental care has fitness implications for both the adopter and orphan, and cases of adoption have thus been cited ...
  • Adult protection in Scotland in 1857 and in 2015 : what have we learned? 

    Campbell, Martin (2016-04-01) - Journal article
    Purpose: The purpose of this paper is to compare recent developments in adult protection legislation, policy and practice in Scotland in 2015 with the first attempts at adult protection of adults at risk of harm, in 1857-62, ...
  • 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 ...
