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...
Perception of animal sentience by Brazilian and French citizens: The case of sheep welfare and sentience
| Contributor(s):: Priscilla Regina Tamioso, Daniel Santiago Rucinque, Mara Miele, Alain Boissy, Carla Forte Maiolino Molento
The study compared the perception of ordinary citizens from Curitiba, Brazil (OB) and Clermont-Ferrand, France (OF), as well as OB, Brazilian veterinarians (VB), biologists (BB) and animal scientists (AB), concerning animal welfare and sentience. An online survey containing 18 open-ended,...
Domestic dogs' understanding of human emotional cues
| Contributor(s):: Min Hooi Yong
Past research has focused on the ability of domestic dogs to recognise human communicative cues such as human pointing, eye gaze, attachment behaviour, social learning, and responses to affective stimuli. However, there is still much to be learned about dogs’ ability to recognise human...
A preliminary study of the effects of individual response to challenge tests and stress induced by humans on learning performance of weaned piglets (Sus scrofa)
| Contributor(s):: Brajon, S., Laforest, J. P., Schmitt, O., Devillers, N.
This study investigated whether individual behavioural characteristics of piglets and stress induced by experience with humans can influence learning performance. After weaning, piglets received a chronic experience with humans to modulate their emotional state: rough (ROU), gentle (GEN), or...
What is suffering in animals?
| Contributor(s):: Weary, D. M., Appleby, M. C., Sandoe, P.
In much of the recent animal welfare literature the word 'suffering' is used simply as an adjunct (as in 'pain and suffering') or to emphasize that the animal consciously perceives pain or some other negative affect. A stronger usage of the term implies that the negative feelings are prolonged,...
Is that fear? Domestic dogs' use of social referencing signals from an unfamiliar person
| Contributor(s):: Yong, MinHooi, Ruffman, T.
The aim of this study was to investigate whether dogs could successfully interpret a 'social referencing' cue (either happiness or fear) toward an object after viewing a human emotional expression. Fearful expressions are more likely to be unfamiliar to dogs, and thus they may not understand the...
Which personality dimensions do puppy tests measure? A systematic procedure for categorizing behavioral assays
| Contributor(s):: McGarrity, M. E., Sinn, D. L., Gosling, S. D.
With the recent increase in interest in personality in dogs, behavioral assays of their behavior have proliferated. There has been particularly strong interest in predicting adult behavior from puppy tests. As a result, researchers and practitioners seeking to measure personality in puppies are...
Repeated exposure to positive events induces optimistic-like judgment and enhances fearfulness in chronically stressed sheep
| Contributor(s):: Destrez, A., Deiss, V., Leterrier, C., Calandreau, L., Boissy, A.
Chronic stress in farm animals can induce detrimental effects in emotional sensitivity and cognitive function, for example, by altering fearfulness and eliciting pessimistic-like judgment. Based on a few experiments carried out on laboratory animals, we suggest that exposing chronically stressed...
Disrupting motivational sequences in chicks: are there affective consequences?

How "natural" training methods can affect equine mental state? A critical approach - a review

Attachment styles impact on pet visitation effectiveness
| Contributor(s):: Colby, Patrcia M., Sherman, Angela
Examined the effects of attachment style (secure, anxious-ambivalent, dismissive avoidant, or fearful avoidant) on the subjective well-being of institutionalized older adults participating in a dog visitation program. The participants were 52 residents of an assisted living facility, aged 58-98...
Vigilance, time budgets and predation risk in reintroduced captive-bred grey partridges Perdix perdix
| Contributor(s):: Rantanen, E. M., Buner, F., Riordan, P., Sotherton, N., Macdonald, D. W.
Anti-predator behaviour has direct fitness consequences for prey species and thereby affects their reintroduction success, which has generally been poor. Development of anti-predator behaviour may be impaired in captive conditions which favour low emotional reactivity, resulting in poor...

The use of diazepam as a pharmacological validation of eye white as an indicator of emotional state in dairy cows
| Contributor(s):: Sandem, A. I., Janczak, A. M., Salte, R., Braastad, B. O.
This experiment aims at validating the percentage of visible white in the eye as an emotional indicator, related to the frustration-contentedness axis, in cattle. Earlier experiments showed that the calculated percentage of white in the eyes was larger in frustrated or scared cows compared to...
The effect of behavioral therapy on dog phobia response patterns
| Contributor(s):: Hoffmann, W. A., Odendaal, J. S. J.
Phobic fear can be regarded as an emotional response syndrome consisting of three groups of response patterns, namely cognitive-affective, motor-behavioral and physiological. In the present study, female students were assigned to two groups: an experimental group consisting of participants...
