    David A Leavens
    Department of Psychology, University of Georgia, Atlanta, GA, USA
    J Comp Psychol 118:48-57. 2004
    ..The capacity for nonverbal reference may predate the Hominidae-Pongidae split, and the development of nonverbal reference may be independent of human species-specific adaptations for speech...
  2. pmc Intentionality as measured in the persistence and elaboration of communication by chimpanzees (Pan troglodytes)
    David A Leavens
    Psychology Department, University of Sussex, Falmer, East Sussex, UK
    Child Dev 76:291-306. 2005
    ..Thus, their communication was about a specific item, demonstrating that both intentionality and nonverbal reference are capacities shared by humans with our nearest living relatives, the great apes...

    David A Leavens
    School of Psychology, University of Sussex, Falmer, East Sussex, UK
    Anim Cogn 15:437-41. 2012
    ..However, points of each hand shape were displayed at each location, demonstrating that these physical parameters do not fully account for the number of fingers extended while pointing by chimpanzees...
  4. doi request reprint BIZARRE chimpanzees do not represent "the chimpanzee"
    David A Leavens
    School of Psychology, University of Sussex, Falmer, East Sussex BN1 9QH, United Kingdom
    Behav Brain Sci 33:100-1. 2010
    ..Here we argue that rearing history is every bit as important for understanding cognition in other species as it is in humans...
  5. doi request reprint Animal communication: laughter is the shortest distance between two apes
    David A Leavens
    Department of Psychology, School of Life Sciences, University of Sussex, Falmer, East Sussex BN1 9QH, UK
    Curr Biol 19:R511-3. 2009
    ..New acoustic analyses of the calls of great apes and humans in response to tickling reveal the probable evolutionary history of laughter in humans and our nearest living relatives, the great apes...
  6. pmc Multimodal communication by captive chimpanzees (Pan troglodytes)
    David A Leavens
    Department of Psychology, School of Life Sciences, University of Sussex, Falmer, East Sussex, BN1 9QH, UK
    Anim Cogn 13:33-40. 2010
    ..Thus, in the impoverished circumstances characteristic of captivity, complex signaling tactics are nevertheless exhibited by chimpanzees, suggesting continuity in intersubjective psychological processes in humans and apes...
  7. ncbi request reprint Animal cognition: multimodal tactics of orangutan communication
    David A Leavens
    Department of Psychology, School of Life Sciences, University of Sussex, Falmer, East Sussex, UK
    Curr Biol 17:R762-4. 2007
    ..Orangutans select different tactics for repairing failed communication, depending upon how well they are understood: they repeat signals if they are partially understood and switch tactics entirely if completely misunderstood...

    Gillian S Forrester
    Department of Psychology, University of Westminster, 309 Regent Street, London W1B 2UW, England, United Kingdom
    Behav Brain Res 237:200-6. 2013

    Gillian S Forrester
    Department of Psychology, University of Westminster, London, UK
    Anim Cogn 15:1121-7. 2012

    Heidi Lyn
    Department of Psychology, University of Southern Mississippi, Gulf Coast 730 East Beach Blvd, Long Beach, MS, 39560, USA
    Anim Cogn 17:85-94. 2014
    ..Comparative studies are of great importance in elucidating the evolution of human cognition; however, greater care must be taken with methodology and interpretation for these studies to accurately reflect species differences. ..

    William D Hopkins
    Division of Psychobiology, Yerkes National Primate Research Center, Atlanta, GA 30322, USA
    Emotion 6:553-9. 2006
    ..For scratching, the chimpanzees showed no hand preference but a significant bias for scratching on the left side of the body. These results support the view that the right hemisphere regulates the autonomic nervous system during arousal...

    PLoS ONE 8:e79338. 2013
