  • 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 ...
  • Are apes essentialists? Scope and limits of psychological essentialism in great apes 

    Cacchione, Trix; Hrubesch, Christine; Call, Josep; Rakoczy, Hannes (2016-09) - Journal article
    Human reasoning is characterized by psychological essentialism (Gelman, 2003): when reasoning about objects we distinguish between deep essential properties defining the object’s kind and identity, and merely superficial ...
  • A general auditory bias for handling speaker variability in speech? Evidence in humans and songbirds 

    Kriengwatana, Buddhamas; Escudero, Paola; Kerkhoven, Anne H.; ten Cate, Carel (2015-08-25) - Journal article
    Different speakers produce the same speech sound differently, yet listeners are still able to reliably identify the speech sound. How listeners can adjust their perception to compensate for speaker differences in speech, ...
  • Great apes and children infer causal relations from patterns of variation and covariation 

    Voelter, Christoph Johannes; Sentís, Inés; Call, Josep (2016-10) - Journal article
    We investigated whether nonhuman great apes (N=23), 2.5-year-old (N=20), and 3-year-old children (N=40) infer causal relations from patterns of variation and covariation by adapting the blicket detector paradigm for apes. ...
  • New Caledonian crows attend to multiple functional properties of complex tools 

    St Clair, James J H; Rutz, Christian (2013-11) - Journal article
    The ability to attend to the functional properties of foraging tools should affect energy-intake rates, fitness components and ultimately the evolutionary dynamics of tool-related behaviour. New Caledonian crows Corvus ...
  • Revisiting vocal perception in non-human animals : a review of vowel discrimination, speaker voice recognition, and speaker normalization 

    Kriengwatana, Buddhamas; Escudero, Paola; ten Cate, Carel (2015-01-13) - Journal item
    The extent to which human speech perception evolved by taking advantage of predispositions and pre-existing features of vertebrate auditory and cognitive systems remains a central question in the evolution of speech. This ...
  • Subjectivity may hinder the application of Kline’s teaching framework in comparative contexts 

    Dean, Lewis; Kendal, Rachel (2015-01) - Journal item
    We welcome Kline’s attempt to develop an overarching framework to allow much needed collaboration between fields in the study of teaching. While we see much utility in this enterprise, we are concerned that there is too ...
  • Tool bending in New Caledonian crows 

    Rutz, Christian; Sugasawa, Shoko; van der Wal, Jessica Eva Megan; Klump, Barbara Christina; St Clair, James (2016-08) - Journal article
    ‘Betty’ the New Caledonian crow astonished the world, when she ‘spontaneously’ bent straight pieces of garden wire into hooked foraging tools. Recent field experiments have revealed that tool bending is part of the species’ ...
  • What can nest-building birds teach us? 

    Breen, Alexis; Guillette, Lauren Mary; Healy, Susan Denise (2016) - Journal article
    For many years nest building in birds has been considered a remarkable behaviour. Perhaps just as remarkable is the public and scholarly consensus that bird nests are achieved by instinct alone. Here we take the opportunity ...
  • Why study cognition in the wild (and how to test it)? 

    Pritchard, David James; Hurly, T. Andrew; Tello-Ramos, Maria Cristina; Healy, Susan Denise (2016-01-18) - Journal article
    An animal's behavior is affected by its cognitive abilities, which are, in turn, a consequence of the environment in which an animal has evolved and developed. Although behavioral ecologists have been studying animals in ...
