    • Call cultures in orang-utans? 

      Wich, Serge A.; Krützen, Michael; Lameira, Adriano R.; Nater, Alexander; Arora, Natasha; Bastian, Meredith L.; Meulman, Ellen; Morrogh-Bernard, Helen C.; Utami Atmoko, S. Suci; Pamungkas, Joko; Perwitasari-Farajallah, Dyah; Hardus, Madeleine E.; van Noordwijk, Maria; van Schaik, Carel P. (2012-05-07) - Journal article
      Background: Several studies suggested great ape cultures, arguing that human cumulative culture presumably evolved from such a foundation. These focused on conspicuous behaviours, and showed rich geographic variation, which ...
    • Can dietary intake influence perception of and measured appearance? A systematic review : dietary intake and appearance 

      Pezdirc, Kristine; Hutchesson, Melinda; Whitehead, Ross David; Ozakinci, Gozde; Perrett, David Ian; Collins, Clare (2015-03) - Journal item
      Appearance-based interventions have had some success in reducing smoking and sun exposure. Appearance may also motivate dietary behavior change if it was established that dietary improvement had a positive impact on ...
    • Causal information and social learning in chimpanzees (Pan troglodytes) and children (Homo sapiens) 

      Horner, Victoria (University of St Andrews, 2004) - Thesis
      Many of the tool-using activities of both chimpanzees and children involve a complex mixture of interconnected causal relationships between a tool and a reward, and much of this tool-use is thought to be acquired, at least ...
    • A causal role for the anterior mid-cingulate cortex in negative affect and cognitive control 

      Tolomeo, S.; Christmas, D.; Jentzsch, Ines; Johnston, B.; Sprengelmeyer, Reiner Heinrich; Matthews, K.; Steele, J.D. (2016-06) - Journal article
      Converging evidence has linked the anterior mid-cingulate cortex to negative affect, pain and cognitive control. Shackman and colleagues proposed this region uses information about punishment to control aversively motivated ...
    • Cerebral hemispheric studies on the visual perception of motion 

      Mackenzie, Alexander (University of St Andrews, 1981) - Thesis
      Experiments were conducted to examine the differential capabilities of the cerebral hemispheres for the visual perception of motion. Subjects were normal right handed adult male and female humans. Stimuli were viewed ...
    • Change point analysis of travel routes reveals novel insights into foraging strategies and cognitive maps of wild baboons 

      Noser, Rahel; Byrne, Richard William (2014-05) - Journal article
      Efficient space use is a critical challenge for animals relying on stationary resources. It is often difficult with purely observational methods to gain unambiguous insight into any ability of primates to manage and process ...
    • Characterizing Visual Attention during Driving and Non-driving Hazard Perception Tasks 

      MacKenzie, Andrew Kerr; Harris, Julie (ACM siggraph, 2014-03-26) - Conference item
      Research into driving skill, particularly of hazard perception, often involves studies where participants either view pictures of driving scenarios or use movie viewing paradigms. However oculomotor strategies tend to ...
    • Children draw more affiliative pictures following priming with third-party ostracism 

      Song, Ruiting; Over, Harriet; Carpenter, Malinda (2015-06) - Journal article
      Humans have a strong need to belong. Thus, when signs of ostracism are detected, adults often feel motivated to affiliate with others in order to re-establish their social connections. This study investigated the importance ...
    • Children's judgements of sameness-difference among schematic faces 

      Roy, Carolyn Mary (University of St Andrews, 1983) - Thesis
      Researchers have found that young children often make "confusion errors" in judging visual stimuli for sameness. That is, children are reported to treat as "just the same" stimuli that are not identical in all respects. ...
    • Chimpanzee (Pan troglodytes) gaze following in the informed forager paradigm : analysis with cross correlations 

      Hall, Katherine McGregor (University of St Andrews, 2012-06-19) - Thesis
      I tested two pairs of captive chimpanzees (Pan troglodytes) in the informed forager paradigm: a subordinate saw the location of hidden bait, and then searched with a naïve dominant. This paradigm has tested what subjects ...
    • Chimpanzee culture extends beyond matrilineal family units 

      van Leeuwen, Edwin J. C.; Mundry, Roger; Cronin, Katherine A.; Bodamer, Mark; Haun, Daniel B. M. (2017-06-19) - Journal article
      The “grooming handclasp” (GHC) is one of the most well-established cultural traditions in chimpanzees. A recent study by Wrangham et al. [1] reduced the cultural scope of GHC behavior by showing that GHC-style convergence ...
    • Chimpanzee lip-smacking facilitates cooperative behaviour 

      Fedurek, Pawel; Slocombe, Katie; Hartel, Jessica A.; Zuberbuehler, Klaus (2015-08-21) - Journal article
      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 ...
    • Chimpanzee quiet hoo variants differ according to context 

      Crockford, Catherine; Gruber, Thibaud; Zuberbuhler, Klaus (2018-05-23) - Journal article
      In comparative studies of evolution of communication, the function and use of animal quiet calls have typically been understudied, despite that these signals are presumably under selection like other vocalisations, such ...
    • Chimpanzee uses manipulative gaze cues to conceal and reveal information to foraging competitor 

      Hall, Katie; Oram, Mike W.; Campbell, Matthew W.; Eppley, Timothy M.; Byrne, Richard W.; de Waal, Frans B. M. (2017-03) - Journal article
      Tactical deception has been widely reported in primates on a functional basis, but details of behavioral mechanisms are usually unspecified. We tested a pair of chimpanzees (Pan troglodytes) in the informed forager paradigm, ...
    • Chimpanzees (Pan troglodytes) display limited behavioural flexibility when faced with a changing foraging task requiring tool use 

      Harrison, Rachel Anne; Whiten, Andrew (2018-02-19) - Journal article
      Behavioural flexibility, the ability to alter behaviour in response to environmental feedback, and to relinquish previously successful solutions to problems, is a crucial ability in allowing organisms to adapt to novel ...
    • Chimpanzees (Pan troglodytes) Flexibly Adjust Their Behaviour in Order to Maximize Payoffs, Not to Conform to Majorities 

      Van Leeuwen, Edwin J. C.; Cronin, Katherine A.; Schutte, Sebastian; Call, Josep; Haun, Daniel B. M. (2013-11-27) - Journal article
      Chimpanzees have been shown to be adept learners, both individually and socially. Yet, sometimes their conservative nature seems to hamper the flexible adoption of superior alternatives, even to the extent that they persist ...
    • Chimpanzees communicate to two different audiences during aggressive interactions 

      Fedurek, Pawel; Slocombe, Katie E.; Zuberbuehler, Klaus (2015-12) - Journal article
      Conflict and aggressive interactions are common phenomena in group-living animals and vocal behaviour often plays an important role in determining their outcomes. In some species, vocal signals seem to provide bystanders ...
    • Chimpanzees coordinate in a snowdrift game 

      Sánchez-Amaro, Alejandro; Duguid, Shona; Call, Josep; Tomasello, Michael (2016-06) - Journal article
      The snowdrift game is a model for studying social coordination in the context of competing interests. We presented pairs of chimpanzees, Pan troglodytes, with a situation in which they could either pull a weighted tray ...
    • Chimpanzees demonstrate individual differences in social information use 

      Watson, Stuart K.; Vale, Gillian L.; Hopper, Lydia M.; Dean, Lewis G.; Kendal, Rachel L.; Price, Elizabeth E.; Wood, Lara A.; Davis, Sarah J.; Schapiro, Steven J.; Lambeth, Susan P.; Whiten, Andrew (2018-06-19) - Journal article
      Studies of transmission biases in social learning have greatly informed our understanding of how behaviour patterns may diffuse through animal populations, yet within-species inter-individual variation in social information ...
    • Chimpanzees prioritise social information over pre-existing behaviours in a group context but not in dyads 

      Watson, Stuart; Lambeth, Susan P.; Schapiro, Steven J.; Whiten, Andrew (2018-03-24) - Journal article
      How animal communities arrive at homogeneous behavioural preferences is a central question for studies of cultural evolution. Here, we investigated whether chimpanzees (Pan troglodytes) would relinquish a pre-existing ...
