  1. Can ear postures reliably measure the positive emotional state of cows?

    Contributor(s):: Proctor, Helen S., Carder, Gemma

    Animal welfare science is increasingly concerned with the promotion of positive emotions in animals, yet little is known about how to measure them. We examined whether ear postures in dairy cows were reliable indicators of a low arousal, positive emotional state. We conducted a total of 381,...

  2. Behaviour of horses in a judgment bias test associated with positive or negative reinforcement

    Full-text: Available

    | Contributor(s):: Briefer Freymond, Sabrina, Briefer, Elodie F., Zollinger, Anja, Gindrat-von Allmen, Yveline, Wyss, Christa, Bachmann, Iris

    Moods can influence our judgment of ambiguous stimuli as positive or negative. Measuring judgment bias in animals is a promising method to objectively assess their emotional states. Our study aimed to develop a cognitive bias test in horses, in order to assess the effect of training using...

  3. Social dimension of emotions and its implication for animal welfare

    | Contributor(s):: Špinka, Marek

    Animal emotions are central to the concept of animal welfare. So far, emotions have been investigated in animal welfare science as within-individual phenomena, i.e. coordinating mechanisms that guide the animal to take appropriate action. However, emotions include an important social dimension....

  4. Measuring empathic responses in animals

    | Contributor(s):: Edgar, J. L., Nicol, C. J., Clark, C. C. A., Paul, E. S.

    Domestic animals may be frequently exposed to situations in which they witness the distress or pain of conspecifics and the extent to which they are affected by this will depend on their capacity for empathy. Empathy encompasses two partially distinct sets of processes concerned with the...

  5. Housing induced mood modulates reactions to emotional stimuli in sheep

    | Contributor(s):: Reefmann, Nadine, Muehlemann, Thomas, Wechsler, Beat, Gygax, Lorenz

    The assessment of positive and negative short-term affective states (emotions) in animals and their modulation by long-term affective states (mood) is an on-going challenge. This study investigated the use of behavioural and physiological measures to assess emotions and their modulation by mood...

  6. Environmental enrichment induces optimistic cognitive biases in pigs

    | Contributor(s):: Douglas, Catherine, Bateson, Melissa, Walsh, Clare, Bédué, Anaïs, Edwards, Sandra A.

    The objective assessment of affective (emotional) state in farm livestock, especially positive states, poses a significant challenge. In human psychology, there is evidence that affective state can alter cognition, with more positive states being associated with an increased likelihood of judging...

  7. Cognitive bias and anticipatory behaviour of laying hens housed in basic and enriched pens

    | Contributor(s):: Wichman, Anette, Keeling, Linda J., Forkman, Björn

    The performances of adult laying hens, housed in either a basic or an enriched pen, were investigated in a cognitive bias and an anticipation test. Both tests were designed to measure the assumed emotional state of the birds. The behaviour of birds in each test was compared to see whether both...

  8. 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...

  9. Adolescents' Affective and Physiological Regulation Shape Negative Behavior During Challenging Equine Assisted Learning Activities

    Full-text: Available

    | Contributor(s):: Patricia Pendry, Alexa M. Carr, Jaymie L. Vandagriff

    This study examined associations between adolescents’ (N = 59; M age = 11.63) diurnal and momentary activity of the Hypothalamic Pituitary Adrenal (HPA) axis as marked by salivary cortisol, and affective and behavioral responses to their first, mounted equine assisted learning (EAL)...

  10. Physiological State of Therapy Dogs during Animal-Assisted Activities in an Outpatient Setting

    | Contributor(s):: Clark, S. D., Martin, F., McGowan, R. T. S., Smidt, J. M., Anderson, R., Wang, L., Turpin, T., Langenfeld-McCoy, N., Bauer, B. A., Mohabbat, A. B.

    Therapy dogs are increasingly being incorporated into numerous clinical settings. However, there are only a handful of studies that have focused on the impact of animal-assisted activity or therapy sessions on the wellbeing of the therapy dogs. Furthermore, these studies show mixed results. The...

  11. Horses feel emotions when they watch positive and negative horse–human interactions in a video and transpose what they saw to real life

    | Contributor(s):: Trösch, Miléna, Pellon, Sophie, Cuzol, Florent, Parias, Céline, Nowak, Raymond, Calandreau, Ludovic, Lansade, Léa

    AbstractAnimals can indirectly gather meaningful information about other individuals by eavesdropping on their third-party interactions. In particular, eavesdropping can be used to indirectly attribute a negative or positive valence to an individual and to adjust one’s future behavior towards...

  12. Do dogs rescue their owners from a stressful situation? A behavioral and physiological assessment

    | Contributor(s):: Carballo, F., Dzik, V., Freidin, E., Damian, J. P., Casanave, E. B., Bentosela, M.

  13. Animal-assisted therapy in a Canadian psychiatric prison

    | Contributor(s):: Dell, C., Chalmers, D., Stobbe, M., Rohr, B., Husband, A.

  14. "There Is a Cat on Our Ward": Inpatient and Staff Member Attitudes toward and Experiences with Cats in a Psychiatric Ward

    | Contributor(s):: Wagner, C., Lang, U. E., Hediger, K.

  15. A qualitative exploration of post-acute stroke participants' experiences of a multimodal intervention incorporating horseback riding

    | Contributor(s):: Pohl, P., Carlsson, G., Bunketorp Kall, L., Nilsson, M., Blomstrand, C.

  16. Dog ownership satisfaction determinants in the owner-dog relationship and the dog's behaviour

    | Contributor(s):: Herwijnen, I. R. V., van der Borg, J. A. M., Naguib, M., Beerda, B.

  17. Let me sniff! Nosework induces positive judgment bias in pet dogs

    | Contributor(s):: Duranton, C., Horowitz, A.

    When confronted with an ambiguous stimulus, an individual’s perception of and behaviour towards the situation are affected by emotional states. In a new situation, positive emotional states lead to optimistic reactions; negative emotional states, to pessimistic reactions. This phenomenon is...

  18. A novel emotional and cognitive approach to welfare phenotyping in rainbow trout exposed to poor water quality

    | Contributor(s):: Colson, V., Mure, A., Valotaire, C., Le Calvez, J. M., Goardon, L., Labbé, L., Leguen, I., Prunet, P.

    Recent scientific evidence for fish sentience has stressed the need for novel sentience-based detection tools of fish welfare impairment in commercial farms. In order to mimic a well-characterised stress situation, rainbow trout (Oncorhynchus mykiss) were exposed to poor water quality (hypoxia...

  19. The nose may not know: Dogs’ reactions to rattlesnake odours

    | Contributor(s):: Mulholland, Michele M., Olivas, Victoria, Caine, Nancy G.

    According to anecdotal reports from dog (Canis lupus familiaris) owners and data from veterinary studies, domestic dogs often fail to avoid, and indeed will approach, venomous snakes. Accordingly, we tested the hypothesis that odours associated with rattlesnakes will elicit investigation, but not...

  20. Boredom-like states in mink and their behavioural correlates: A replicate study

    | Contributor(s):: Meagher, Rebecca K., Campbell, Dana L. M., Mason, Georgia J.

    Scientists and laypeople have long expressed concern that animals in non-enriched, unchanging environments might experience boredom. However, this had attracted little empirical study: the state is difficult to assess without verbal self-reports, and spontaneous behavioural signs of boredom can...
