  • The coevolution of building nests on the ground and domed nests in Timaliidae 

    Hall, Z.J.; Street, S.E.; Auty, S.; Healy, S.D. (2015-07) - Journal article
    Despite the accumulation of structural descriptions of bird nests and considerable diversity in these structures across species, we know little about why birds build the nests that they do. Here we used phylogenetic ...
  • 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 ...
  • The coevolution of innovation and technical intelligence in primates 

    Navarrete Rodriguez, Ana Francisca; Reader, Simon M.; Street, Sally E.; Whalen, Andrew; Laland, Kevin N. (2016-03) - Journal article
    In birds and primates, the frequency of behavioural innovation has been shown to covary with absolute and relative brain size, leading to the suggestion that large brains allow animals to innovate, and/or that selection ...
  • The coevolution of virulence : tolerance in perspective 

    Little, Tom J.; Shuker, David M.; Colegrave, Nick; Day, Troy; Graham, Andrea L. (2010-09) - Journal item
    Coevolutionary interactions, such as those between host and parasite, predator and prey, or plant and pollinator, evolve subject to the genes of both interactors. It is clear, for example, that the evolution of pollination ...
  • Cognition in inter-group relations : the effect of group membership on theory of mind and its precursors 

    McClung, Jennifer (University of St Andrews, 2012) - Thesis
    Social categorization based on group membership has a significant and broad influence on behaviour (Turner, Hogg, Oakes, Reicher, & Wetherell, 1987). People perceived as being of the same group, ‘in-group’ members, are ...
  • Cognitive ability is heritable and predicts the success of an alternative mating tactic 

    Smith, Carl; Phillips, Andre; Reichard, Martin (2015-06-22) - Journal article
    The ability to attract mates, acquire resources for reproduction, and successfully outcompete rivals for fertilisations may make demands on cognitive traits - the mechanisms by which an animal acquires, processes, stores, ...
  • Cognitive and brain function in adults with Type 1 diabetes mellitus : is there evidence of accelerated ageing? 

    Johnston, Harriet N. (University of St Andrews, 2013-06-25) - Thesis
    The physical complications of Type 1 diabetes mellitus (T1DM) have been understood as an accelerated ageing process (Morley, 2008). Do people with T1DM also experience accelerated cognitive and brain ageing? Using findings ...
  • The cognitive and motor deficits of Parkinson's disease. 

    Gauntlett-Gilbert, Jeremy (University of St Andrews, 1999-03) - Thesis
    Deficits of attentional and motor set that are seen in patients with PD were investigated in the research reported in this thesis. A deficit of attentional set is a failure of selective attention to one aspect of a complex ...
  • Cognitive and neural processes underlying memory for time and context 

    Persson, Bjorn Martin (University of St Andrews, 2017-06-20) - Thesis
    The aim of this thesis is to examine the underlying cognitive and neural processes at play during retrieval of temporal and contextual source information. This was assessed across three experimental chapters. In the first ...
  • A cognitive approach to the study of culture in wild chimpanzees (Pan troglodytes schweinfurthii) 

    Gruber, Thibaud (University of St Andrews, 2011-11-30) - Thesis
    The question of animal culture has been of interest for decades. Chimpanzees (Pan troglodytes) have played a key role in the debate of whether or not it is appropriate to use the term ‘culture’ to describe animal behaviour ...
  • Cognitive aspects of travel and food location by chimpanzees (Pan troglodytes schweinfurthii) of the Budongo Forest Reserve, Uganda 

    Bates, Lucy (University of St Andrews, 2005) - Thesis
    Finding food in tropical forests poses a potentially major problem for chimpanzees, whose ranging is thought primarily to be directed at locating suitable food resources: (1) chimpanzees are frugivorous, large bodied and ...
  • Cognitive control of heart rate in diving harbor porpoises 

    Elmegaard, Siri; Johnson, Mark; Madsen, Peter; McDonald, Birgitte (2016-11-21) - Journal article
    Marine mammals have adapted to forage while holding their breath in a suite of aquatic habitats from shallow rivers to deep oceans. The key to tolerate such extensive apnea is the dive response, which comprises bradycardia ...
  • Cognitive differences between orang-utan species: a test of the cultural intelligence hypothesis 

    Forss, Sofia I. F.; Willems, Erik; Call, Josep; van Schaik, Carel P. (2016-07-28) - Journal article
    Cultural species can-or even prefer to-learn their skills from conspecifics. According to the cultural intelligence hypothesis, selection on underlying mechanisms not only improves this social learning ability but also the ...
  • Cognitive impairments in developmental dyslexia 

    Duncan, Lynne G. (University of St Andrews, 1992-07) - Thesis
    The nature of cognitive impairments in developmental dyslexia was investigated in two studies. The issue of heterogeneity was addressed and an attempt was made to identify cognitive processes which might feature in a ...
  • Cognitive processes associated with sequential tool use in New Caledonian crows 

    Wimpenny, Joanna H.; Weir, Alex A. S.; Clayton, Lisa; Rutz, Christian; Kacelnik, Alex (2009-08-05) - Journal article
    Background: Using tools to act on non-food objects-for example, to make other tools-is considered to be a hallmark of human intelligence, and may have been a crucial step in our evolution. One form of this behaviour, ...
  • A cognitive prosthesis and communication support for people with dementia 

    Alm, N; Astell, Arlene Jean; Ellis, Maggie; Dye, R; Gowans, G; Campbell, J (2004-03) - Journal article
    Computers may have the potential to augment human cognitive processes in ways that could be beneficial for people with dementia. This possibility is being investigated by a multidisciplinary team. Previous work on improving ...
  • Coherence dynamics and quantum-to-classical crossover in an exciton-cavity system in the quantum strong coupling regime 

    Kasprzak, J.; Sivalertporn, K.; Albert, F.; Schneider, C.; Höfling, Sven; Kamp, M.; Forchel, A.; Reitzenstein, S.; Muljarov, E. A.; Langbein, W. (2013-04-22) - Journal article
    Interaction between light and matter generates optical nonlinearities, which are particularly pronounced in the quantum strong coupling regime. When a single bosonic mode couples to a single fermionic mode, a Jaynes-Cummings ...
  • Coherence protection in coupled quantum systems 

    Cammack, Helen Mary; Kirton, Peter George; Stace, Thomas; Eastham, Paul; Keeling, Jonathan Mark James; Lovett, Brendon William (2018-02) - Journal article
    The interaction of a quantum system with its environment causes decoherence, setting a fundamental limit on its suitability for quantum information processing. However, we show that if the system consists of coupled parts ...
  • Coherent and passive one dimensional quantum memory 

    Ping, Y.; Jefferson, J.H.; Lovett, B.W. (2014-10-16) - Journal article
    We show that the state of a flying qubit may be transferred to a chain of identical, (near) ferromagnetically polarized, but non-interacting, static spin-1/2 particles in a passive way. During this process the flying qubit ...
  • Coherent control of plasmonic nanoantennas using optical eigenmodes 

    Kosmeier, Sebastian; De Luca, Anna Chiara; Zolotovskaya, Svetlana; Di Falco, Andrea; Dholakia, Kishan; Mazilu, Michael (2013-05-09) - Journal article
    The last decade has seen subwavelength focusing of the electromagnetic field in the proximity of nanoplasmonic structures with various designs. However, a shared issue is the spatial confinement of the field, which is ...
