  1. The efficacy of systematic desensitization for treating the separation-related problem behaviour of domestic dogs

    Contributor(s):: Butler, Rynae, Sargisson, Rebecca J., Elliffe, Douglas

    The evaluation of systematic desensitization to treat separation-related problem behaviours, such as destruction of property, excessive barking, or house-soiling, has tended to rely on single case-studies. Eight dogs exhibiting separation-related behaviour, and their owners, participated in a...

  2. Do pigs distinguish between situations of different emotional valences during anticipation?

    Contributor(s):: Imfeld-Mueller, Sabrina, Van Wezemael, Lea, Stauffacher, Markus, Gygax, Lorenz, Hillmann, Edna

    An animal's welfare is strongly affected by its emotional state. Thus, many recent studies have focused on measuring the emotional states and responses of animals. However, there is still a lack of knowledge on assessing positive emotions, although it is widely accepted that positive emotions are...

  3. Do children understand man's best friend? Classification of dog barks by pre-adolescents and adults

    Contributor(s):: Pongrácz, Péter, Molnár, Csaba, Dóka, Antal, Miklósi, Ádám

    Play back experiments compared the ability of children (aged 6, 8, and 10 years) and adults to discriminate dog barks recorded in three different contexts. Participants had to categorize barks according to recording context, and to characterize the inner states of dogs by relating barks to facial...

  4. Degree of social isolation affects behavioural and vocal response patterns in dwarf goats (Capra hircus)

    Contributor(s):: Siebert, Katrin, Langbein, Jan, Schön, Peter-Christian, Tuchscherer, Armin, Puppe, Birger

    Separation from the group presents a serious challenge for social animals. This stressful and disagreeable situation can impair animal welfare and may have an undesirable impact on experimental data in scientific studies. In the present study, we observed whether different degrees of social...

  5. Behavioural fear and heart rate responses of horses after exposure to novel objects: Effects of habituation

    Contributor(s):: Leiner, Lisa, Fendt, Markus

    The emotion fear promotes the fitness of wild animals. In a farm environment, exaggerated fear, e.g., in horses, can cause several problems. Therefore, knowledge about fear in horses helps to prevent or to handle potential fear-inducing situations. The present study investigated which behavioural...

  6. Early recognition of offspring vocalisation by mink mothers

    Contributor(s):: Malmkvist, Jens

    Mink deliver around the same time of year. Consequently, mink dams are exposed to other delivering dams and litters nearby in the same housing facility on farms. In addition, farmers often transfer kits between litters within the first week of life, as levelling large litters is believed to...

  7. Maternal nest building and choice of nest site are temperature dependent in mink: Parent-offspring temperature conflict?

    Contributor(s):: Schou, Toke Munk, Malmkvist, Jens

    We investigated whether nest building and nest site preference are temperature dependent in female mink. We designed two experiments: in Experiment 1, female mink had access to unheated (7 °C, Room7C group) or heated (25 °C, Heated25C group) nest boxes; in Experiment 2, female mink had free...

  8. Should I whine or should I bark? Qualitative and quantitative differences between the vocalizations of dogs with and without separation-related symptoms

    Contributor(s):: Pongrácz, Péter, Lenkei, Rita, Marx, András, Faragó, Tamás

    Separation-related disorder (SRD) is one of the most common behavioral problems of companion dogs, causing inconvenience and stress for dog owners and others living close by, as well as being considered as a major contributor to poor animal welfare. Although excessive vocalization is considered...

  9. Cats and owners interact more with each other after a longer duration of separation

    Full-text: Available

    | Contributor(s):: Matilda Eriksson, Linda J. Keeling, Therese Rehn

    Little is known about the cat’s (Felis silvestris catus) need for human contact, although it is generally believed that cats are more independent pets than e.g. dogs. In this study, we investigated the effect of time left alone at home on cat behaviour (e.g. social and distress-related)...

  10. The effects of cage color and light intensity on rat affect during heterospecific play

    | Contributor(s):: LaFollette, Megan R., Swan, Melissa P., Smith, Rebecca K., Hickman, Debra L., Gaskill, Brianna N.

  11. Cheetahs discriminate familiar and unfamiliar human voices

    Full-text: Available

    | Contributor(s):: Maël Leroux, Robyn Shelia Hetem, Martine Hausberger, Alban Lemasson

    Domestic species can make the distinction between several human sub-groups, especially between familiar and unfamiliar persons. The Domestication hypothesis assumes that such advanced cognitive skills were driven by domestication itself. However, such capacities have been shown in wild species...

  12. Fear vs. frustration - Possible factors behind canine separation related behaviour

    | Contributor(s):: Lenkei, R., Alvarez Gomez, S., Pongracz, P.

  13. Pet dog management practices among a representative sample of owners in Victoria, Australia

    | Contributor(s):: Howell, T. J., Mornement, K., Bennett, P. C.

    It is often assumed that pet dogs experience better welfare than livestock production animals because many owners consider them to be members of the family and, collectively, spend billions of dollars on them annually. However, this assumption is not based on scientific evidence, and a...

  14. Examining dog-human play: the characteristics, affect, and vocalizations of a unique interspecific interaction

    | Contributor(s):: Horowitz, A., Hecht, J.

    Despite the growing interest in research on the interaction between humans and dogs, only a very few research projects focus on the routines between dogs and their owners. In this study, we investigated one such routine: dog-human play. Dyadic interspecific play is known to be a common...

  15. Owners' direct gazes increase dogs' attention-getting behaviors

    | Contributor(s):: Ohkita, M., Nagasawa, M., Kazutaka, M., Kikusui, T.

  16. Bottlenose Dolphins' (Tursiops truncatus) Theory of Mind as Demonstrated by Responses to their Trainers' Attentional States

    | Contributor(s):: Masaki Tomonaga, Yuka Uwano

    The present study examined the ability of dolphins to follow the gestural signs presented by humantrainers in various attentional states in order to understand the social cognition of dolphins. Thehuman trainers enacted the gestural signs by orienting their bodies and heads in different...

  17. Dog growls express various contextual and affective content for human listeners

    | Contributor(s):: T Faragó, N Takács, A Miklósi, P Pongrácz

    Vocal expressions of emotions follow simple rules to encode the inner state of the caller into acoustic parameters, not just within species, but also in cross-species communication. Humans use these structural rules to attribute emotions to dog vocalizations, especially to barks, which match with...

  18. Owners' direct gazes increase dogs' attention-getting behaviors

    | Contributor(s):: Ohkita, M., Nagasawa, M., Kazutaka, M., Kikusui, T.

  19. Of Mice, Birds, and Men: The Mouse Ultrasonic Song System Has Some Features Similar to Humans and Song-Learning Birds

    | Contributor(s):: Gustavo Arriaga, Eric P. Zhou, Erich D. Jarvis

    Humans and song-learning birds communicate acoustically using learned vocalizations. The characteristic features of this social communication behavior include vocal control by forebrain motor areas, a direct cortical projection to brainstem vocal motor neurons, and dependence on auditory feedback...

  20. Reduced locomotor play behaviour of dairy calves following separation from the mother reflects their response to reduced energy intake

    | Contributor(s):: Rushen, Jeff, Wright, Rebecca, Johnsen, Julie Føske, Mejdell, Cecilie Marie, de Passillé, Anne Marie

    Play behaviour is an indicator of good welfare in young calves and is reduced by low energy intake and weaning off milk. There is renewed interest in keeping calves longer with the cow but separation leads to signs of distress, such as vocalizations. Providing calves with an alternative milk...
