Canine Emotions: Guidelines For Research, Miiamaaria V. Kujala
Canine Emotions: Guidelines For Research, Miiamaaria V. Kujala
Animal Sentience
In the target article, I called for a discussion on the nature and extent of dogs’ emotions. The commentators generally agreed on the existence of dog emotions, but the diversity and quality of dog emotions, as well as the influence of human social cognition on perceiving dog emotions, raised more debate. To respond to the stimulating commentaries, I touch briefly on the philosophy of (canine) mind and discuss further the benefits of comparing cognition across species, secondary emotions, and the shaping of canine emotions by evolution, breeding and experience. I conclude with suggestions for future research guidelines on studies of …
Can Neuroimaging In Dogs Have Practical Implications?, Tiffani J. Howell
Can Neuroimaging In Dogs Have Practical Implications?, Tiffani J. Howell
Animal Sentience
Jealousy, or at least aggression, can be observed in dogs using neuroimaging techniques, but this response attenuates quickly following repeated exposure to the aggression-inducing stimulus. This may have a practical application. Early socialisation as a puppy, and habituation as an adult dog, could help prevent undesirable behaviours such as predatory behaviour. It is unclear whether these processes are the same, and affected only by the dog’s age. Neuroimaging could help us understand whether the same neurological processes underlie socialisation and habituation, and whether self-rewarding behaviours such as predatory behaviour could be stopped using socialisation/habituation techniques.
Sentient Plants? Nervous Minds?, Arthur S. Reber
Sentient Plants? Nervous Minds?, Arthur S. Reber
Animal Sentience
The commentaries by Calvo (2018) and Mallatt & Feinberg (2017) on my 2016 target branch out from a common conceptual node like forks in a road. Calvo criticizes me for not acknowledging that plants too are likely to be sentient and claims I have fallen into the kind of category error of which I accuse others ─ a zoocentric bias that fails to grant consciousness to flora. Mallatt & Feinberg maintain that I've gone too far in granting sentience to any species that lacks a nervous system. Calvo makes some good points but there are other issues concerning plant sentience …
The Many Faces Of Fear And Vigilance, Guy Beauchamp
The Many Faces Of Fear And Vigilance, Guy Beauchamp
Animal Sentience
In the target article, I examined the relationship between vigilance and fear in prey animals. The joint occurrence of vigilance and other physiological responses to fear, such as increased heart rate and stress hormone release, would bolster the idea that vigilance can be a useful marker of fear. Nevertheless, a common theme in much of the empirical research is an uncoupling of vigilance and physiological correlates of fear. The commentators suggest several ways to refine the concepts of vigilance, fear, and risk. I discuss these refinements, which in the end will prove useful to assess further the relationship between vigilance …
Fish And Plant Sentience: Anesthetized Plants And Fishes Cannot Respond To Stimuli, Ken Yokawa, František Baluška
Fish And Plant Sentience: Anesthetized Plants And Fishes Cannot Respond To Stimuli, Ken Yokawa, František Baluška
Animal Sentience
Recent denial of fish sentience is at variance with the fact that all living organisms need environmental awareness in order to survive in a continuously fluctuating environment. Moreover, fish sentience – like plant sentience – is also strongly supported by the sensitivity of fishes and plants to diverse anesthetics.
Degrees Of Sentience?, Jonathan Birch
Degrees Of Sentience?, Jonathan Birch
Animal Sentience
I focus on the possibility of sentience in zebrafish larvae. The evidence here prompts two intuitive reactions that are difficult to reconcile: the reaction that larvae, if sentient, should be protected in some way, and the reaction that larvae, if capable of nociception, should be used as replacements for adults. Both reactions are reasonable, but they can be reconciled only by constructing a framework for assigning degrees of protection in proportion to degrees of sentience.
Fish Are Smart And Feel Pain: What About Joy?, Becca Franks, Jeff Sebo, Alexandra Horowitz
Fish Are Smart And Feel Pain: What About Joy?, Becca Franks, Jeff Sebo, Alexandra Horowitz
Animal Sentience
Sneddon et al. rightly point out that the evidence of fish pain is now so strong and comprehensive that arguments against it have become increasingly difficult to defend in balanced academic discourse. But sentience involves more than just pain. Recent research indicates that fish have an impressive range of cognitive capacities, including the capacity for pleasure, in the form of play and other behaviors likely to involve positively valenced experience. Having made the case for pain, research can now focus on other aspects of fish sentience. Doing so will not only provide a more complete picture of the mental lives …
Ample Evidence For Fish Sentience And Pain, Lynne U. Sneddon, David C.C. Wolfenden, Matthew C. Leach, Ana M. Valentim, Peter J. Steenbergen, Nabila Bardine, Donald M. Broom, Culum Brown
Ample Evidence For Fish Sentience And Pain, Lynne U. Sneddon, David C.C. Wolfenden, Matthew C. Leach, Ana M. Valentim, Peter J. Steenbergen, Nabila Bardine, Donald M. Broom, Culum Brown
Animal Sentience
The majority of commentaries are supportive of our position on the scepticism that muddies the waters surrounding fish pain and sentience. There is substantial empirical evidence for pain in fish. Animals’ experience of pain cannot be compared to artificial intelligence (AI) because AI can only mimic responses to nociceptive input on the basis of human observations and programming. Accepting that fish are sentient would not be detrimental to the industries reliant on fish. A more proactive discussion between scientists and stakeholders is needed to improve fish welfare for the benefit of all.
Limits Of Neuroscience, Paul Morris
Limits Of Neuroscience, Paul Morris
Animal Sentience
Examining the relationship between jealous behaviour and the amygdala may be quite informative about the function of the amygdala, but the amygdala may be less helpful in informing us about jealous behaviour. Claims about the potential practical relevance of the results also require that the magnitude of the effects inform the relevant discussion. The dogs used in the study probably share some very important personality characteristics; this too limits the practical implications of Cook et al.’s findings for dogs in general. It is nevertheless a testament to the skill of the experimenters, and the amazing bond between dogs and humans, …
Using Anthropocentrism To The Benefit Of Other Species, Vanessa Wilson
Using Anthropocentrism To The Benefit Of Other Species, Vanessa Wilson
Animal Sentience
Chapman & Huffman (2018) argue that we should not consider humans as unique or superior to other animals when we have the chance to explore the diversity of the traits of other species. This is a valid and progressive point in our approach to research, but I suggest that an anthropocentric approach can have animal welfare benefits when it helps us perceive other species – especially distantly related ones such as crustaceans – in a human light.
Individuals In The Wild, Bob Fischer
Individuals In The Wild, Bob Fischer
Animal Sentience
If many wild animals have net negative lives, then we have to consider how likely it is that the good for animals, considered as individuals, aligns with the good for species, or the climate, or the preservation of wild spaces.
How To Foster Respect For Animals? Superiority, Dissimilarity, And Prejudice, Matteo Colombo
How To Foster Respect For Animals? Superiority, Dissimilarity, And Prejudice, Matteo Colombo
Animal Sentience
Chapman & Huffman (C & H) might be taken to argue as follows: Humans may treat animals however they want only if humans are superior to animals. But humans are not superior to animals. Therefore, humans may not treat animals however they want. Whatever its merit, this is not C & H’s actual argument. Their point, instead, is that humans often mistreat animals because they tend to perceive them as inferior. A remedy for animal mistreatment would then be acknowledging the deep similarities between us and animals. But is C & H’s suggested remedy likely to be effective to foster …
What Sets Us Apart Could Be Our Salvation, Anne Fawcett, Paul Mcgreevy
What Sets Us Apart Could Be Our Salvation, Anne Fawcett, Paul Mcgreevy
Animal Sentience
We agree with Chapman & Huffman that human capacities are often assumed to be unique — or attempts are made to demonstrate uniqueness scientifically — in order to justify the exploitation of animals and ecosystems. To extend the argument that human exceptionalism is against our interests, we recommend adopting the One Welfare framework, according to which animal welfare, environmental sustainability and human wellbeing are inseparably linked. Let us distinguish ourselves from other animals by resisting our short- and mid-term Darwinian inclinations, consuming less, reproducing less, and striving for a much longer-term biological fitness for us all.
Fish Consciousness, David Gamez
Fish Consciousness, David Gamez
Animal Sentience
Woodruff makes two arguments to support his claim that ray-finned fish are conscious: (1) Fish neuroanatomy has similarities with the structures in the human brain that support consciousness. (2) The complexity and flexibility of fish behaviour suggest that they are conscious. This commentary will argue that neither the neuroanatomical nor the behavioural argument can provide conclusive evidence for consciousness in fish. We should suspend judgement until we have discovered mathematical theories of consciousness that can reliably map between states of consciousness and states of the physical world.
Jealousy In Dogs? Evidence From Brain Imaging, Peter Cook, Ashley Prichard, Mark Spivak, Gregory S. Berns
Jealousy In Dogs? Evidence From Brain Imaging, Peter Cook, Ashley Prichard, Mark Spivak, Gregory S. Berns
Animal Sentience
Domestic dogs are highly social and have been shown to be sensitive not only to the actions of humans and other dogs but to the interactions between them. We used the C-BARQ scale to estimate dogs’ aggressiveness, and we used noninvasive brain imaging (fMRI) to measure activity in their amygdala (an area involved in aggression). More aggressive dogs had more amygdala activation data while watching their caregiver give food to a realistic fake dog than when they put the food in a bucket. This may have some similarity to human jealousy, adding to a growing body of evidence that differences …
Situating The Study Of Jealousy In The Context Of Social Relationships, Christine E. Webb, Frans B. M. De Waal
Situating The Study Of Jealousy In The Context Of Social Relationships, Christine E. Webb, Frans B. M. De Waal
Animal Sentience
Whereas the feelings of other beings are private and may always remain so, emotions are simultaneously manifested in behavior, physiology, and other observables. Nonetheless, uncertainty about whether emotions can be studied adequately across species has promoted skepticism about their very presence in other parts of the animal kingdom. Studying social emotions like jealousy in the context of the social relationships in which they arise, as has been done in the case of animal empathy, may help dispel this skepticism. Empathy in other species came to be accepted partly because of the behavioral similarities between its expression in nonhuman animals and …
The Inconvenient Truth About Thinking Chickens, Lori Marino
The Inconvenient Truth About Thinking Chickens, Lori Marino
Animal Sentience
Original Abstract: Domestic chickens are members of an order, Aves, which has been the focus of a revolution in our understanding of neuroanatomical, cognitive, and social complexity. Some birds are now known to be on a par with many mammals in their intelligence, emotional sophistication, and social interaction. Yet views of chickens have largely remained unrevised in light of this new evidence. In this paper, I examine the data on cognition, emotions, personality, and sociality in chickens, exploring such areas as self-awareness, cognitive bias, social learning and self-control, and comparing their abilities with other birds and other vertebrates, particularly …
Raising Consciousness About Chicken Consciousness, Bernard Rollin
Raising Consciousness About Chicken Consciousness, Bernard Rollin
Animal Sentience
The topics explored by Marino are definitive, and should work well to lay to rest forever the widespread belief that chickens have no personality, are unintelligent, or in any other way lack a mental life.
Chickens’ Brains, Like Ours, Are Lateralized, Lesley J. Rogers
Chickens’ Brains, Like Ours, Are Lateralized, Lesley J. Rogers
Animal Sentience
This commentary draws attention to yet another attribute that has been instrumental in demonstrating the cognitive abilities of domestic chicks: lateralization of brain function. The discovery of lateralization in domestic chicks was part of the first evidence showing that humans are not unique in this respect. The effects on cognitive ability of sensory stimulation in critical stages of development have implications for the welfare of chicks, as well as other species.
Are Chicken Minds Special?, Rafael Freire, Susan J. Hazel
Are Chicken Minds Special?, Rafael Freire, Susan J. Hazel
Animal Sentience
The number of publications on chicken cognition and emotion exceeds that on most birds and is comparable to the number of publications on some more “advanced” mammals. We argue that the chicken is an excellent model for this type of research because of (1) the presence of well-established fundamental mental processes in the chicken, (2) a challenging ethological environment and (3) social pressures that may have facilitated the evolution of cognitive abilities similar to those of some mammals. Marino’s (2017) review provides an excellent foundation for the continued study of complex mental abilities in this species.
Chicken Of The Sea, Jonathan Balcombe
Chicken Of The Sea, Jonathan Balcombe
Animal Sentience
Marino summarizes research showing that chickens perform cognitively and emotionally at a higher level than previously assumed. Here, I describe capacities of teleost fishes that parallel those of chickens, including the ability to recognize human faces, perspective-taking, and referential communication. Research on chickens and on fishes reveals an emerging trend in cognitive ethology: abilities once thought limited to a scant few highly intelligent non-humans may actually occur broadly across taxa.

Chickening Out Of Change: Will Knowing More About Thinking Chickens Change Public Perceptions?, Ewan Bottomley, Steve Loughnan
Chickening Out Of Change: Will Knowing More About Thinking Chickens Change Public Perceptions?, Ewan Bottomley, Steve Loughnan
Animal Sentience
This commentary examines the next step in Marino’s target article – changing people’s attitudes and beliefs about chickens. The scientific case seems clear: chickens are far more complex, psychologically and socially, than originally thought. Marino suggests we use this information to make people feel uncomfortable about their dietary choices in the hope of changing them. We review the psychological literature, examining how people maintain meat consumption despite the clash with their moral beliefs (the “meat paradox”). This work highlights the important gap between what science knows about animals and what people think about animals.
Evolutionary Continuity, Anne Benvenuti
Evolutionary Continuity, Anne Benvenuti
Animal Sentience
The principle of evolutionary continuity states that all animal capacities and behaviors exist — with variations in degree — in continuity with other species. Rather than assuming discontinuity, we should ask why any behavior observed in humans would not be found in at least some other sentient animals under similar conditions. In the case of suicide, the more pertinent issue might be the ethical one: our human responsibility for creating conditions under which other animals might deliberately seek to end their own lives.
Non-Human Animal Suicide Could Be Tested, David Lester
Non-Human Animal Suicide Could Be Tested, David Lester
Animal Sentience
Schaefer (1967) showed that mice can discriminate live from dead mice and lethal from nonlethal environments, and that they avoid a lethal environment; but the experiment lacked some controls. This might be a way to test whether mice would ever choose a lethal environment. Humans may also choose a potentially lethal environment unconsciously.
Understanding Animal Suicide And Death Can Lead To Better End-Of-Life Care, Jessica Pierce
Understanding Animal Suicide And Death Can Lead To Better End-Of-Life Care, Jessica Pierce
Animal Sentience
Peña-Guzmán’s target article on animal suicide will help inform end-of-life care for animals by emphasizing the need for a broad research focus on animal thanatology. Greater scientific understanding of the continuum of death-related awareness, experiences, and behaviors will help us improve veterinary care for animals at the end of life.
Complicated Grief, Teya Brooks Pribac
Complicated Grief, Teya Brooks Pribac
Animal Sentience
My commentary discusses complicated grief and the ensuing sense of helplessness that may lead to suicide. I close with a story about a pygmy pig.
Can Nonhuman Animals Commit Suicide?, David M. Peña-Guzmán
Can Nonhuman Animals Commit Suicide?, David M. Peña-Guzmán
Animal Sentience
Many people believe that only humans have the cognitive and behavioral capacities needed for suicidal behavior, such as reflexive subjectivity, free will, intentionality, or awareness of death. Three counterarguments — based on (i) negative emotions and psychopathologies among nonhuman animals, (ii) the nature of self-destructive behavior, and (iii) the problem of model fidelity in suicide research — suggest that self-destructive and self-injurious behaviors among human and nonhuman animals vary along a continuum.

Sentience Does Not Require “Higher” Cognition, Giorgio Vallortigara
Animal Sentience
I agree with Marino (2017a,b) that the cognitive capacities of chickens are likely to be the same as those of many others vertebrates. Also, data collected in the young of this precocial species provide rich information about how much cognition can be pre-wired and predisposed in the brain. However, evidence of advanced cognition — in chickens or any other organism — says little about sentience (i.e., feeling). We do not deny sentience in human beings who, because of cognitive deficits, would be incapable of exhibiting some of the cognitive feats of chickens. Moreover, complex problem solving, such as transitive inference, …
