“…In parallel, the area of research investigating the ability of various animal species, including companion animals, to experience a range of positive and negative emotions (both basic and complex) is experiencing exponential growth. This includes, but is not limited to, pain, fear, joy, anger, disgust, regret, compassion, empathy, depression, and surprise (Yue, Moccia and Duncan 2004;Custance and Mayer 2012;Meridda, Gazzano and Mariti 2014).…”

The Emotional Lives of Companion Animals: Attachment and Subjective Claims by Owners of Cats and Dogs

There is a growing body of scientific evidence supporting the existence of emotions in nonhuman animals. Companion-animal owners show a strong connection and attachment to their animals and readily assign emotions to them. In this paper we present information on how the attachment level of companion-animal owners correlates with their attribution of emotions to their companion cat or dog and their attribution of mirrored emotions. The results of an online questionnaire, completed by 1,023 Dutch-speaking cat and/or dog owners (mainly in the Netherlands and Belgium), suggest that owners attribute several emotions to their pets. Respondents attributed all posited basic (anger, joy [happiness], fear, surprise, disgust, and sadness) and complex (shame, jealousy, disappointment, and compassion) emotions to their companion animals, with a general trend toward basic emotions (with the exception of sadness) being more commonly attributed than complex emotions. All pet owners showed strong attachment to their companion animal(s), with the degree of attachment (of both cat and dog owners) varying significantly with education level and gender. Owners who ascribed human characteristics to their dog or cat also scored higher on the Pet Bonding Scale (PBS). Finally, owners who found it pleasant to pet their dog or cat had a higher average PBS score than those who did not like to do so. The relationship between owners' attributions of mirrored emotions and the degree of attachment to dogs was significant for all emotions, whilst for cats this relationship was significant only for joy, sadness, surprise, shame, disappointment, and compassion.

“…This behaviour may occur, for example, as a defensive mechanism against fear (e.g. Yue et al, 2004), or as an anti-predator defence (e.g. Vilhunen & Hirvonen, 2003).…”

“…Avoidance learning tasks are a common paradigm in fear research, revealing a consistent pattern of avoidance behaviours (e.g. Portavella et al, 2003;Yue et al, 2004). Yue and colleagues (2004) have shown how the behavioural responses of rainbow trout to fearful stimuli are of a non-reflexive nature and how they can make conscious choices to avoid future frightening stimuli.…”

Galhardo L, Oliveira RF. Psychological Stress and Welfare in Fish. Annu Rev Biomed Sci 2009;11:1-20. The ability to respond to stress is vital to the survival of any living organism, though sustained reactions can become detrimental to the health and welfare of animals. Stress responses of vertebrates are known through several studies in their physiological, behavioural and psychological components, under acute and chronic contexts. In fish, the physiological and behavioural aspects of stress are considerably well known phenomena and show striking similarities to those of other vertebrates. However, the psychological component is not well known. Some authors deny mental experiences to fish on the basis of their lack of neocortex. Nevertheless, recent studies have shown neuroendocrine, cognitive and emotional processes in fish that are not only equivalent to other vertebrates, but also allow inferring some forms of mental representation. The integration of psychological elements in fish stress physiology is insufficiently studied, but, as discussed in this article, there is already indirect evidence to admit that some form of stimuli appraisal can take place in fish. This fact has profound implications on the regulation of the stress response, as well as on fish welfare and its management.

“…A habilidade cognitiva de reconhecimento e realização de certo comportamento que evitará uma situação aversiva é evidência de que o comportamento exibido não seja uma manifestação automática inconsciente (YUE et al, 2004).…”

“…Os indicadores de medo que têm sido referenciados para peixes incluem o aumento da taxa respiratória, a produção de feromônios de alarme e as reações comportamentais de aversão, nomeadamente a fuga rápida e o distanciamento (CHANDROO et al, 2004). Usando paradigmas de condicionamento operacional e clássico, YUE et al (2004) demonstraram como trutas arco-íris (Oncorhynchus mykiss) aprendem através de uma associação de estímulos, a evitar um evento percebido como perigoso, sendo capazes de obter um aprendizado envolvendo memória de longa duração (mais de sete dias). O tipo de resposta comportamental exibida (fuga) mostrou-se flexível e adaptativo, pois o seu tempo de latência variou com a exposição ao estímulo, sendo menor na presença do evento adverso (estímulo não condicionado) que em relação ao estímulo condicionado (que originalmente antecedia e sinalizava a ocorrência do evento adverso).…”

resumo -No Brasil, assim como em outras partes do mundo, a preocupação com o bem-estar dos peixes encontra-se em seus passos iniciais. O bem-estar de peixes, se comparado com o bemestar de outras espécies de animais de produção, é um tópico praticamente ausente para consumidores, produtores e legislação vigente. Porém, as evidências anatômicas, fisiológicas, comportamentais, evolutivas e farmacológicas sugerem que os peixes experimentam sentimentos como dor, medo e outros de maneira similar aos demais vertebrados. Isso sugere que os peixes têm potencialmente a capacidade de sofrer e apresentar outros sentimentos, ou seja, que os peixes são seres sencientes. Esta revisão teve como objetivo discutir aspectos referentes à dor e à presença de consciência nos peixes, visando colaborar com o entendimento da senciência nesses animais. Uma vez reconhecida a senciência em peixes, estes animais são incluí-dos nas considerações éticas acerca de não serem submetidos a sofrimento. palavras-chave: Senciência; cognição; consciên-cia; dor; teleósteo.abstract -In Brazil, as well as in other parts of the World, the concern about fish welfare is in its initials steps. Fish welfare, if compared to the welfare of other species of farm animals, is practically an absent topic for consumers, producers and current law. However, anatomic, physiologic, behavioral, evolutive and pharmacologic evidences suggest that fish experience feelings such as pain, fear and others, in ways that are similar to other vertebrates. This suggests that fish are potentially capable of experiencing suffering and other feelings; in other words, that fish are sentient. The objective of this review was to discuss pain and consciousness in fish, in order to collaborate with sentience understanding in these animals. Once fishes are recognized as sentient beings, these animals are then included into ethical considerations regarding the avoidance of suffering infliction.
