  1. Anxiety influences attention bias but not flight speed and crush score in beef cattle

    Contributor(s):: Lee, Caroline, Cafe, Linda M., Robinson, Samantha L., Doyle, Rebecca E., Lea, Jim M., Small, Alison H., Colditz, Ian G.

    Attentional biases towards threatening stimuli are increased when animals are in anxious states. An ability to assess negatively valanced affective states such as anxiety are important as they may be related to poor welfare. Flight speed and crush score are two well established tests of...

  2. Applying welfare science to bottlenose dolphins (Tursiops truncatus)

    Contributor(s):: Clegg, I. L. K., Van Elk, C. E., Delfour, F.

  3. Artificial rearing affects the emotional state and reactivity of pigs post-weaning

    Contributor(s):: Schmitt, O., O'Driscoll, K., Baxter, E. M., Boyle, L. A.

  4. Assessing the emotions of laboratory rats

    Contributor(s):: Makowska, I. Joanna, Weary, Daniel M.

    Rats are one of the most commonly used species in research, and decades of testing have yielded a large amount of information pertaining to their experience of emotion. The aim of this review is to bring together information on rat emotion from across a number of disciplines and over several...

  5. Cognitive Bias in Zoo Animals: An Optimistic Outlook for Welfare Assessment

    Full-text: Available

    | Contributor(s):: Isabella L. K. Clegg

    Cognitive bias testing has emerged as one of the most valid tools in measuring animals’ affective states, and while it has been extensively applied in farm and laboratory settings, only a few studies have taken place in zoos and aquaria. This review evaluates past cognitive bias studies...

  6. Conceptualising the Impact of Arousal and Affective State on Training Outcomes of Operant Conditioning

    | Contributor(s):: Melissa J. Starling, Nicholas Branson, Denis Cody, Paul D. McGreevy

    Animal training relies heavily on an understanding of species-specific behaviour as it integrates with operant conditioning principles. Following on from recent studies showing that affective states and arousal levels may correlate with behavioural outcomes, we explore the contribution of both...

  7. Cross sectional study comparing behavioural, cognitive and physiological indicators of welfare between short and long term kennelled domestic dogs

    | Contributor(s):: Titulaer, Mieke, Blackwell, Emily J., Mendl, Michael, Casey, Rachel A.

    Affective states are an integral part of animal welfare but are difficult to assess using traditional welfare measurements. It has previously been shown that kennelled dogs commonly show indications of poor welfare. The aim of this study was to compare welfare of short-term (ST) and long-term...

  8. Current perspectives on attachment and bonding in the dog–human dyad

    Full-text: Available

    | Contributor(s):: Payne, Elyssa, Bennett, Pauleen C., McGreevy, Paul D.

    This article reviews recent research concerning dog–human relationships and how attributes that arise from them can be measured. It highlights the influence of human characteristics on dog behavior, and consequently, the dog–human bond. Of particular importance are the influences of...

  9. Disrupting motivational sequences in chicks: Are there affective consequences?

    | Contributor(s):: Seehuus, Birgitte, Mendl, Mike, Keeling, Linda J., Blokhuis, Harry

    The ‘reward cycle’ conceptualises reward acquisition as a cyclic phenomenon divided into three motivational stages with related emotional or affective states. For feeding behaviour such a cycle consists of an appetitive stage characterised by foraging and exploration linked to emotions such as...

  10. Effects of brief exposure to a pet therapy dog on affective states of HIV-positive men

    | Contributor(s):: Pepper, Tory Deborah

  11. Effects of stereotypic behaviour and chronic mild stress on judgement bias in laboratory mice

    | Contributor(s):: Novak, Janja, Stojanovski, Klement, Melotti, Luca, Reichlin, Thomas S., Palme, Rupert, Würbel, Hanno

    Cognitive processes are influenced by underlying affective states, and tests of cognitive bias have recently been developed to assess the valence of affective states in animals. These tests are based on the fact that individuals in a negative affective state interpret ambiguous stimuli more...

  12. Enhanced understanding of horse-human interactions to optimize welfare

    Full-text: Available

    | Contributor(s):: Merkies, K., Franzin, O.

    Horses (Equus caballus) have been domesticated for millennia and are regularly utilized for work, sport, and companionship. Enhanced understanding of human–horse interactions can create avenues to optimize their welfare. This review explores the current research surrounding many aspects of...

  13. 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...

  14. Evidence of horsemanship and dogmanship and their application in veterinary contexts

    | Contributor(s):: Payne, E., Boot, M., Starling, M., Henshall, C., McLean, A., Bennett, P., McGreevy, P.

    This review collates peer-reviewed evidence for desirable attributes for those who work with dogs and horses. It is written with a particular focus on the veterinary profession. Although veterinarians and veterinary nurses (VNs) occupy variable roles when interacting with their patients, several...

  15. Evidence of negative affective state in Cavalier King Charles Spaniels with syringomyelia

    | Contributor(s):: Cockburn, Alastair, Smith, Melissa, Rusbridge, Clare, Fowler, Carol, Paul, Elizabeth S., Murrell, Joanna C., Blackwell, Emily J., Casey, Rachel A., Whay, Helen R., Mendl, Michael

    Syringomyelia is a common and chronic neurological disorder affecting Cavalier King Charles Spaniels. The condition is putatively painful, but evaluating the affective component of chronic pain in non-human animals is challenging. Here we employed two methods designed to assess animal affect -...

  16. Frustration in horses: Investigating expert opinion on behavioural indicators and causes using a delphi consultation

    | Contributor(s):: Pannewitz, Laura, Loftus, Loni

  17. Generating positive affective states in sheep: The influence of food rewards and opioid administration

    | Contributor(s):: Verbeek, Else, Ferguson, Drewe, Quinquet de Monjour, Patrick, Lee, Caroline

    This study investigated the involvement of the opioid system in modulating the affective state after the consumption of palatable and unpalatable rewards, using judgement bias as an indicator of the affective state. We hypothesised that consuming a palatable food reward would generate a more...

  18. Human-Animal Relations in Business and Society: Advancing the Feminist Interpretation of Stakeholder Theory

    Full-text: Available

    | Contributor(s):: Tallberg, L., García-Rosell, J. C., Haanpää, M.

    Stakeholder theory has largely been anthropocentric in its focus on human actors and interests, failing to recognise the impact of nonhumans in business and organisations. This leads to an incomplete understanding of organisational contexts that include key relationships with nonhuman animals....

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

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

  20. Investigating putative depression-like states in the domestic dog: Does greater time spent displaying waking inactivity in the home kennel co-vary with negative judgment of ambiguity?

    | Contributor(s):: Harvey, Naomi D., Moesta, Alexandra, Wongsaengchan, Chanakarn, Harris, Hannah, Craigon, Peter J., Fureix, Carole

    Exposure to chronic stressors and/or traumatic events can trigger depression-like forms of waking inactivity in non-human species (mice, horses, primates) as well as clinical depression in humans. This study aimed to test the hypothesis that elevated levels of waking inactivity in the home...
