Background: Evidence from humans suggests that the expression of emotions can regulate social interactions and promote coordination within a group. Despite its evolutionary importance, social communication of emotions in non-human animals is still not well understood. Here, we combine behavioural and physiological measures, to determine if animals can distinguish between vocalisations linked to different emotional valences (positive and negative). Using a playback paradigm, goats were habituated to listen to a conspecific call associated with positive or negative valence (habituation phase) and were subsequently exposed to a variant of the same call type (contact call) associated with the opposite valence (dishabituation …

Functional asymmetries, for example, the preferential involvement of 1 brain hemisphere to process stimuli, may increase brain efficiency and the capacity to carry out tasks simultaneously. We investigated which hemisphere was primarily involved in processing acoustic stimuli in goats using a head-orienting paradigm. Three playbacks using goat vocalizations recorded in different contexts: food anticipation (positive), isolation (negative), food frustration (negative), as well as 1 playback involving dog barks (negative) were presented on the left and right sides of the test subjects simultaneously. The head-orienting response (left or right) and latency to resume feeding were recorded. The direction of the head-orienting …

Emotion Collection
Emotions can be defined as an individual’s affective reaction to an external and/or internal event that, in turn, generates a simultaneous cascade of behavioral, physiological, and cognitive changes. Those changes that can be perceived by conspecifics have the potential to also affect other’s emotional states, a process labeled as “emotional contagion.” Especially in the case of gregarious species, such as livestock, emotional contagion can have an impact on the whole group by, for instance, improving group coordination and strengthening social bonds. We noticed that the current trend of research on emotions in livestock, i.e., investigating affective states as a tool …

Social Cognition Collection
Domestication has shaped the physiology and the behaviour of animals to better adapt to human environments. Therefore, human facial expressions may be highly informative for animals domesticated for working closely with people, such as dogs and horses. However, it is not known whether other animals, and particularly those domesticated primarily for production, such as goats, are capable of perceiving human emotional cues. In this study, we investigated whether goats can distinguish human facial expressions when simultaneously shown two images of an unfamiliar human with different emotional valences (positive/ happy or negative/angry). Both images were vertically attached to a wall on …

Measuring emotions in nonhuman mammals is challenging. As animals are not able to verbally report how they feel, we need to find reliable indicators to assess their emotional state. Emotions can be described using two key dimensions: valence (negative or positive) and arousal (bodily activation or excitation). In this study, we investigated vocal expression of emotional valence in wild boars (Sus scrofa). The animals were observed in three naturally occurring situations: anticipation of a food reward (positive), affiliative interactions (positive), and agonistic interactions (negative). Body movement was used as an indicator of emotional arousal to control for the effect of …

Judgement Bias In Goats (Capra Hircus): Investigating The Effects Of Human Grooming, Luigi Baciadonna, Christian Nawroth, Alan G. Mcelligott
Emotion Collection
Animal emotional states can be investigated by evaluating their impact on cognitive processes. In this study, we used a judgement bias paradigm to determine if shortterm positive human-animal interaction (grooming) induced a positive affective state in goats. We tested two groups of goats and trained them to discriminate between a rewarded and a non-rewarded location over nine training days. During training, the experimental group (nD9) was gently groomed by brushing their heads and backs for five min over 11 days (nine training days, plus two testing days, total time 55 min). During training, the control group (nD10) did not experience …

The Use Of Judgement Bias To Assess Welfare In Farm Livestock, L. Baciadonna, A. G. Mcelligott
Sentience Collection
The development of accurate measures of animal emotions is important for improving and promoting animal welfare. Cognitive bias indicates the effect of emotional states on cognitive processes, such as memory, attention, and judgement. Cognitive bias tests complement existing behavioural and physiological measures for assessing the valence of animal emotions indirectly. The judgement bias test has been used to assess emotional states in non-human animals; mainly in laboratory settings. The aim of this review is to summarise the findings on the use of the judgement bias test approach in assessing emotions in non-human animals, focusing in particular on farm livestock. The …

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 positive reinforcement (PR) or negative reinforcement (NR) on their emotional states. We trained 12 mares to discriminate between a rewarded and a non-rewarded location situated on each side of a paddock. The mares were then trained during five days to perform several exercises using PR (n = 6) for one group, and NR …
Rescued Goats At A Sanctuary Display Positive Mood After Former Neglect, Elodie F. Briefer, Alan G. Mcelligott
Rescued Goats At A Sanctuary Display Positive Mood After Former Neglect, Elodie F. Briefer, Alan G. Mcelligott
Sentience Collection
Moods influence cognitive processes in that people in positive moods expect more positive events to occur and less negative ones (“optimistic bias”), whereas the opposite happens for people in negative moods (“pessimistic bias”). The evidence for an effect of mood on cognitive bias is also increasing in animals, suggesting that measures of optimism and pessimism could provide useful indicators of animal welfare. For obvious ethical reasons, serious poor treatments cannot be easily replicated in large mammals in order to study their long-term effects on moods. In this study, we tested the long-term effects (>2 years) of prior poor welfare …

Equine Welfare As A Mainstream Phenomenon, Bernard E. Rollin
Equine Husbandry and Welfare Collection
The 20th century has witnessed a bewildering array of ethical revolutions, from civil rights to environmentalism to feminism. Often ignored is the rise of massive societal concern across the world regarding animal treatment. Regulation of animal research exists in virtually all Western countries, and reform of “factory farming” is regnant in Europe and rapidly emerging in the United States. In 2012, a series of articles in The New York Times focused welfare attention squarely on the horse industry. Opponents of concern for animals often dismiss the phenomenon as rooted in emotion and extremist lack of appreciation of how unrestricted animal …
Distress Or Suffering: What Should Be Measured To Determine Animal Well-Being?, Ian J. H. Duncan
Distress Or Suffering: What Should Be Measured To Determine Animal Well-Being?, Ian J. H. Duncan
Sentience Collection
It is generally accepted that all the vertebrates and some of the invertebrates (those with large neural ganglia such as the cephalopods) are capable of subjective experiences. Amongst those experiences are the subjective, affective states, sometimes called 'feelings' or 'emotions'. The strong negative feelings are often lumped together as 'suffering' and the positive feelings as 'pleasure'. I have argued for many years that animal welfare/well-being is completely dependent on what the animal feels (Duncan, 1993, 1996, 2002). An animal's well-being is decreased by experiencing suffering and increased by experiencing pleasure. It's as simple as that.

Distress In Animals: Its Recognition And A Hypothesis For Its Assessment, David B. Morton
Sentience Collection
This essay deals with the recognition of non-painful emotional experiences in animals, how they relate to animal wellbeing and animal welfare, and how they can be assessed, monitored and mitigated. While it is written often from a mammalian perspective, the general principles will apply to all animals that are sentient.
Politics Or Metaphysics? On Attributing Psychological Properties To Animals, Kristin Andrews
Politics Or Metaphysics? On Attributing Psychological Properties To Animals, Kristin Andrews
Sentience Collection
Following recent arguments that there is no logical problem with attributing mental or agential states to animals, I address the epistemological problem of how to go about making accurate attributions. I suggest that there is a two-part general method for determining whether a psychological property can be accurately attributed to a member of another species: folk expert opinion and functionality. This method is based on well-known assessments used to attribute mental states to humans who are unable to self-ascribe due to an early stage of development or impairment, and can be used to describe social and emotional development as well …

The emotional effects of euthanizing unwanted animals on professional animal control personnel are examined using written statements of and discussions among twenty-six euthanasia technicians at a workshop during a national session of the Animal Control Academy (Tuscaloosa, AL]. Emotional conflicts arise .in significant part from the dilemma that the same public which is responsible for the problem of unwanted animals also has a markedly negative perception of euthanasia, and by extension, of those who perform euthanasia. During discussions, the euthanasia technicians revealed a variety of strategies for coping with feelings of isolation, alienation and sorrow. These included intellectualization, avoidance of …
