    • Adjusting foraging strategies : a comparison of rural and urban common mynas (Acridotheres tristis) 

      Federspiel, Ira G.; Garland, Alexis; Guez, David; Bugynar, Thomas; Healy, Susan D.; Güntürkün, Onur; Griffin, Andrea S. (2017-01) - Journal article
      Establishment in urbanized environments is associated with changes in physiology, behaviour, and problem-solving. We compared the speed of learning in urban and rural female common mynas, Acridotheres tristis, using a ...
    • Distribution of independent components of binocular natural images 

      Hunter, David William; Hibbard, Paul Barry (2015-09) - Journal article
      An influential theory of the function of early processing in the visual cortex is that it forms an efficient coding of ecologically valid stimuli. In particular, correlations and differences between visual signals from the ...
    • How chimpanzees (Pan troglodytes) perform in a modified emotional Stroop task 

      Allritz, Matthias; Call, Josep; Borkenau, Peter (2016-05) - Journal article
      The emotional Stroop task is an experimental paradigm developed to study the relationship between emotion and cognition. Human participants required to identify the color of words typically respond more slowly to negative ...
    • Intuitive optics : what great apes infer from mirrors and shadows 

      Völter, Christoph J.; Call, Josep (2018-05-02) - Journal article
      There is ongoing debate about the extent to which nonhuman animals, like humans, can go beyond first-order perceptual information to abstract structural information from their environment. In order to provide more empirical ...
    • No evidence for contagious yawning in lemurs 

      Reddy, Rachna B.; Krupenye, Christopher; MacLean, Evan L.; Hare, Brian (2016-09-01) - Journal article
      Among some haplorhine primates, including humans, relaxed yawns spread contagiously. Such contagious yawning has been linked to social bonds and empathy in some species. However, no studies have investigated contagious ...
    • The origins of language in teaching 

      Laland, Kevin N. (2017-02) - Journal article
      I introduce seven criteria for determining the validity of competing theories for the original function of language. I go on to present a novel explanation that meets all the criteria: language originally evolved to teach ...
    • Proto-consonants were information-dense via identical bioacoustic tags to proto-vowels 

      Lameira, Adriano R.; Vicente, Raquel; Alexandre, António; Campbell-Smith, Gail; Knott, Cheryl; Wich, Serge; Hardus, Madeleine E. (2017-02-08) - Journal article
      Why did our ancestors combine the first consonant- A nd vowel-like utterances to produce the first syllable or word? To answer this question, it is essential to know what constituted the communicative function of ...
    • Social play as joint action : a framework to study the evolution of shared intentionality as an interactional achievement 

      Heesen, Raphaela; Genty, Emilie; Rossano, Federico; Zuberbühler, Klaus; Bangerter, Adrian (2017-12) - Journal article
      Social play has a complex, cooperative nature that requires substantial coordination. This has led researchers to use social games to study cognitive abilities like shared intentionality, the skill and motivation to share ...
    • Thirty years of great ape gestures 

      Tomasello, Michael; Call, Josep (2018-02-21) - Journal article
      We and our colleagues have been doing studies of great ape gestural communication for more than 30 years. Here we attempt to spell out what we have learned. Some aspects of the process have been reliably established by ...
    • Where have all the (ape) gestures gone? 

      Byrne, Richard W.; Cochet, Hélène (2017-02) - Journal article
      Comparative analysis of the gestural communication of our nearest animal relatives, the great apes, implies that humans should have the biological potential to produce and understand 60–70 gestures, by virtue of shared ...
    • Women’s facial redness increases their perceived attractiveness : mediation through perceived healthiness 

      Pazda, Adam D.; Thorstenson, Christopher A.; Elliot, Andrew J.; Perrett, David I. (2016-07-01) - Journal article
      In the present research, we investigated whether the red-attraction relation that has been observed for men viewing women may also be observed with regard to women’s facial redness. We manipulated facial redness by slightly ...
