  1. Automatic brushes induce positive emotions and foster positive social interactions in group-housed horses

    Contributor(s):: Lansade, Léa, Lemarchand, Julie, Reigner, Fabrice, Arnould, Cécile, Bertin, Aline

  2. Human Preferences for Conformation Attributes and Head-And-Neck Positions in Horses

    Full-text: Available

    | Contributor(s):: Georgina L. Caspar, Navneet K. Dhand, Paul D. McGreevy

    Human preferences for certain morphological attributes among domestic animals may be entirely individual or, more generally, may reflect evolutionary pressures that favor certain conformation. Artificial selection for attributes, such as short heads and crested necks of horses, may have...

  3. The recognition of canine pain behaviours, and potentially hazardous Catch-Neuter-Return practices by animal care professionals

    | Contributor(s):: Bacon, H. J., Walters, H., Vancia, V., Waran, N.

  4. Humans can identify cats' affective states from subtle facial expressions

    | Contributor(s):: Dawson, L. C., Cheal, J., Niel, L., Mason, G.

  5. Lambs show changes in ear posture when experiencing pain

    | Contributor(s):: Guesgen, M. J., Beausoleil, N. J., Minot, E. O., Stewart, M., Stafford, K. J., Morel, P. C. H.

  6. What can kinematics tell us about the affective states of animals?

    | Contributor(s):: Guesgen, M. J., Bench, C. J.

  7. Studying dog emotion beyond expression and without concern for feeling

    Full-text: Available

    | Contributor(s):: Peter F. Cook

    Studies of dog emotion have focused on the expression of social emotion, either because this is taken to suggest human-like feeling states in dogs or because it has been the most accessible signal of dog emotional processing. I argue for an approach grounded in affective neuroscience, relying...

  8. The neural basis of understanding the expression of the emotions in man and animals

    Full-text: Available

    | Contributor(s):: Robert P. Spunt, Emily Ellsworth, Ralph Adolphs

    Humans cannot help but attribute human emotions to non-human animals. Although such attributions are often regarded as gratuitous anthropomorphisms and held apart from the attributions humans make about each other’s internal states, they may be the product of a general mechanism for...

  9. Slow Blink Eye Closure in Shelter Cats is Related to Quicker Adoption

    | Contributor(s):: Humphrey, T., Stringer, F., Proops, L., McComb, K.

  10. The ability to recognize dog emotions depends on the cultural milieu in which we grow up

    Full-text: Available

    | Contributor(s):: Amici, F., Waterman, J., Kellermann, C. M., Karimullah, K., Bräuer, J.

    Inter-specific emotion recognition is especially adaptive when species spend a long time in close association, like dogs and humans. Here, we comprehensively studied the human ability to recognize facial expressions associated with dog emotions (hereafter, emotions). Participants were presented...

  11. Dogs (Canis familiaris) recognise our faces in photographs: implications for existing and future research

    | Contributor(s):: Eatherington, C. J., Mongillo, P., Looke, M., Marinelli, L.

  12. Juvenile pigs use simple geometric 2D shapes but not portrait photographs of conspecifics as visual discriminative stimuli

    | Contributor(s):: Gieling, Elise T., Musschenga, Maartje A., Nordquist, Rebecca E., van der Staay, F. Josef

    Several animals living in social groups, such as monkeys, cows and sheep, have been shown to use facial discrimination for social recognition. Whether pigs can discriminate between faces of conspecifics purely based on visual stimuli provided by 2D portrait photographs, has not yet been...

  13. Evolution of facial muscle anatomy in dogs

    | Contributor(s):: Kaminski, J., Waller, B. M., Diogo, R., Hartstone-Rose, A., Burrows, A. M.

    Domestication shaped wolves into dogs and transformed both their behavior and their anatomy. Here we show that, in only 33,000 y, domestication transformed the facial muscle anatomy of dogs specifically for facial communication with humans. Based on dissections of dog and wolf heads, we show that...

  14. Face-based perception of emotions in dairy goats

    | Contributor(s):: Bellegarde, Lucille G. A., Haskell, Marie J., Duvaux-Ponter, Christine, Weiss, Alexander, Boissy, Alain, Erhard, Hans W.

    Faces of conspecifics convey information about identity, but also gaze, and attentional or emotional state. As a cognitive process, face-based emotion recognition can be subject to judgement bias. In this study we investigated whether dairy goats (n=32) would show different responses to 2-D...

  15. Development and application of CatFACS: Are human cat adopters influenced by cat facial expressions?

    | Contributor(s):: Caeiro, C. C., Burrows, A. M., Waller, B. M.

    The domestic cat (Felis silvestris catus) is quickly becoming the most popular animal companion in the world. The evolutionary processes that occur during domestication are known to have wide effects on the morphology, behaviour, cognition and communicative abilities of a species. Since facial...

  16. Initial evaluation of facial expressions and behaviours of harbour seal pups (Phoca vitulina) in response to tagging and microchipping

    | Contributor(s):: MacRae, Amelia Mari, Joanna Makowska, I., Fraser, David

    There are no proven species-specific indicators of pain in harbour seals (Phoca vitulina). The analysis of facial expressions has proven to be a repeatable, accurate and valid method of identifying pain in multiple species, but facial expressions have not been examined in any species of pinniped....

  17. Why Pain Is Still a Welfare Issue for Farm Animals, and How Facial Expression Could Be the Answer

    Full-text: Available

    | Contributor(s):: Krista Marie McLennan

    Pain is a sensory and emotional experience that significantly affects animal welfare and has negative impacts on the economics of farming. Pain is often associated with common production diseases such as lameness and mastitis, as well as introduced to the animal through routine husbandry...

  18. Conceptual and methodological issues relating to pain assessment in mammals: The development and utilisation of pain facial expression scales

    | Contributor(s):: McLennan, Krista M., Miller, Amy L., Dalla Costa, Emanuela, Stucke, Diana, Corke, Murray J., Broom, Donald M., Leach, Matthew C.

  19. Face scanning in autism spectrum disorder and attention deficit/hyperactivity disorder: human versus dog face scanning

    Full-text: Available

    | Contributor(s):: Mauro Muszkat, Claudia Berlim de Mello, Patricia de Oliveira Lima Muñoz, Tania Khiel Lucci, Vinicius Frayze David, José de Oliveira Siqueira, Emma Otta

    This study used eye tracking to explore attention allocation to human and dog faces in children and adolescents with autism spectrum disorder (ASD), attention deficit/hyperactivity disorder (ADHD), and typical development (TD). Significant differences were found among the three groups. TD...

  20. Human Facial Recognition by Northern Mockingbirds

    Full-text: Available

    | Contributor(s):: Jessica A. Stehlin, Janice Crook-Hill, Brad Bailey

    A number of studies have examined the ability of various animal species to recognize individual humans, but only a few have focused on native, non-captive birds. Previous research demonstrated that American Crows learn to recognize individual human faces. Other research indicated that Northern...
