    • Kin-based cultural transmission of tool use in wild chimpanzees 

      Lamon, Noemie; Neumann, Christof; Gruber, Thibaud; Zuberbühler, Klaus (2017-04-26) - Journal article
      Current research on animal culture has focused strongly on cataloging the diversity of socially transmitted behaviors and on the social learning mechanisms that sustain their spread. Comparably less is known about the ...
    • Knowing without knowing : implicit cognition and the minds of infants and animals 

      Gomez, Juan-Carlos; Kersken, Verena Angela; Ball, Derek Nelson; Seed, Amanda Madeleine (2017) - Journal article
      The main aim of this paper is to highlight the need to address the conceptual problem of “implicit knowledge” or “implicit cognition” —a notion especially important in the study of the nonverbal minds of animals and infants. ...
    • Labels facilitate infants' comparison of action goals 

      Gerson, Sarah; Woodward, Amanda (2014) - Journal article
      Understanding the actions of others depends on the insight that these actions are structured by intentional relations. In a number of conceptual domains, comparison with familiar instances has been shown to support children's ...
    • Late presentation with HIV in Africa : phenotypes, risk, and risk stratification in the REALITY trial 

      Siika, Abraham; McCabe, Leanne; Bwakura-Dangarembizi, Mutsa; Kityo, Cissy; Mallewa, Jane; Berkley, Jay; Maitland, Kath; Griffiths, Anna; Baleeta, Keith; Mudzingwa, Shepherd; Abach, James; Nathoo, Kusum; Thomason, Margaret J.; Prendergast, Andrew J.; Walker, Ann Sarah; Gibb, Diana M.; Mugyenyi, P.; Kityo, C.; Musiime, V.; Wavamunno, P.; Nambi, E.; Ocitti, P.; Ndigendawani, M.; Kemigisa, M.; Acen, J.; Olebo, D.; Mpamize, G.; Amone, A.; Okweny, D.; Mbonye, A.; Nambaziira, F.; Rweyora, A.; Kangah, M.; Kabaswahili, V.; Abach, J.; Abongomera, G.; Omongin, J.; Aciro, I.; Philliam, A.; Arach, B.; Ocung, E.; Amone, G.; Miles, P.; Adong, C.; Tumsuiime, C.; Kidega, P.; Otto, B.; Apio, F.; Baleeta, K.; O'Hare, B. (2018-04-01) - Journal article
      Background. Severely immunocompromised human immunodefciency virus (HIV)-infected individuals have high mortality shortly afer starting antiretroviral therapy (ART). We investigated predictors of early mortality and "late ...
    • Lateral entorhinal cortex is necessary for associative but not nonassociative recognition memory 

      Wilson, David Ian Greig; Watanabe, Sakurako; Milner, Helen Louise; Ainge, James Alexander (2013-12) - Journal article
      The lateral entorhinal cortex (LEC) provides one of the two major input pathways to the hippocampus and has been suggested to process the nonspatial contextual details of episodic memory. Combined with spatial information ...
    • Laterality in the gestural communication of wild chimpanzees 

      Hobaiter, Cat; Byrne, Richard William (2013) - Journal article
      e examined hand preference in the intentional gestural communication of wild chimpanzees in the Budongo forest, Uganda. Individuals showed some tendency to be lateralized, although less than has been reported for begging ...
    • Learning from their own actions : the unique effect of producing actions on infants’ action understanding 

      Gerson, Sarah; Woodward, Amanda (2014-02) - Journal article
      Prior research suggests that infants' action production affects their action understanding, but little is known about the aspects of motor experience that render these effects. In Study 1, the relative contributions of ...
    • Learning how to learn : the development of memory in 3-6 year-olds 

      Whittaker, Stephen (University of St Andrews, 1984) - Thesis
      The aim of the present study was to investigate the development of children's ability to make use of external sources of information when they are studying or remembering different types of information. More specifically, ...
    • Learning to focus and focusing to learn : more than a cortical trick 

      Dhawan, Sandeep Sonny (University of St Andrews, 2018-12-06) - Thesis
      The consequence of many psychiatric and neurodegenerative disorders, such as Parkinson’s disease and schizophrenia, is an impairment in ‘executive functioning’; an umbrella term for several cognitive processes, including ...
    • Learning to use illumination gradients as an unambiguous cue to three dimensional shape 

      Harding, Glen; Harris, Julie; Bloj, Marina (2012-04-30) - Journal article
      The luminance and colour gradients across an image are the result of complex interactions between object shape, material and illumination. Using such variations to infer object shape or surface colour is therefore a difficult ...
    • Light activated escape circuits : a behavior and neurophysiology lab module using Drosophila optogenetics 

      Titlow, Joshua S.; Johnson, Bruce R.; Pulver, Stefan R. (2015-07-07) - Journal article
      The neural networks that control escape from predators often show very clear relationships between defined sensory inputs and stereotyped motor outputs. This feature provides unique opportunities for researchers, but it ...
    • Limitations to the cultural ratchet effect in young children 

      Tennie, Claudio; Walter, Victoria; Gampe, Anja; Carpenter, Malinda; Tomasello, Michael (2014-10) - Journal article
      Although many animal species show at least some evidence of cultural transmission, broadly defined, only humans show clear evidence of cumulative culture. In the current study, we investigated whether young children show ...
    • Linguistic capacity of non-human animals 

      Zuberbuehler, Klaus (2015-05) - Journal article
      Linguists interested in language evolution tend to focus on combinatorial features and rightly point out the lack of comparable evidence in animal communication. However, human language is based on various unique capacities, ...
    • Linguistic laws in chimpanzee gestural communication 

      Heesen, Raphaela; Hobaiter, Catherine; Ferrer-i-Cancho, Ramon; Semple, Stuart (2019-02-13) - Journal article
      Studies testing linguistic laws outside language have provided important insights into the organization of biological systems. For example, patterns consistent with Zipf's law of abbreviation (which predicts a negative ...
    • A link between attentional function, effective eye movements and driving ability 

      MacKenzie, Andrew Kerr; Harris, Julie (2017-02) - Journal article
      The misallocation of driver visual attention has been suggested as a major contributing factor to vehicle accidents. One possible reason is that the relatively high cognitive demands of driving limits the ability to ...
    • Linking 3D face shape to social perception 

      Holzleitner, Iris J. (University of St Andrews, 2015-09) - Thesis
      Advances in computer graphic and statistical methods have made it possible to visualise global face shape correlates of social judgments. The current thesis used a data-driven approach to investigate face shape correlates ...
    • Linking actions to outcomes: the role of the posterior pedunculopontine tegmental nucleus in instrumental learning 

      MacLaren, Duncan A. A. (University of St Andrews, 2012-11-01) - Thesis
      Located in the mesopontine tegmentum, the pedunculopontine tegmental nucleus (PPTg) is comprised principally of glutamatergic, cholinergic and GABAergic neurons. In addition to being fully integrated into basal ganglia, ...
    • Listeners can extract meaning from non-linguistic infant vocalisations cross-culturally 

      Kersken, Verena; Zuberbühler, Klaus; Gomez, Juan-Carlos (2017-01-25) - Journal article
      We present empirical evidence showing that the acoustic properties of non-linguistic vocalisations produced by human infants in different cultures can be used cross-culturally by listeners to make inferences about the ...
    • Living in stable social groups is associated with reduced brain size in woodpeckers (Picidae) 

      Fedorova, Natalia; Evans, Cara L.; Byrne, Richard W. (2017-03) - Journal article
      Group size predicts brain size in primates and some other mammal groups, but no such relationship has been found in birds. Instead, stable pair-bonding and bi-parental care have been identified as correlates of larger ...
    • Maintaining personhood and self-image in dementia : an exploration of collaborative communication 

      Ellis, Maggie P. (University of St Andrews, 2009) - Thesis
      The main aim of this thesis was to explore the maintenance of personhood and self-image in dementia by way of facilitating collaborative communication between people with dementia and their caregivers/interaction partners. ...
