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 …
What Is It Like To Be A Jealous Dog?, Emanuela Prato Previde, Paola Valsecchi
What Is It Like To Be A Jealous Dog?, Emanuela Prato Previde, Paola Valsecchi
Animal Sentience
Jealousy is a good candidate for comparative studies due to its clear adaptive value in protecting social bonds and affective relationships. Dogs are suitable subjects for investigating the evolution of jealousy, thanks to their rather sophisticated socio-cognitive abilities — which in some cases parallel those reported for human infants — and thanks to their long-lasting relationship with humans. The work of Cook and colleagues (2018) addresses the issue of jealousy in dogs through the lens of neuroscience, examining the relationship between the amygdala and jealousy. Their experiment has a number of methodological flaws that prevent distinguishing jealousy from other internal …
Fake Or Not: Two Prerequisites For Jealousy, Juliane Bräuer, Federica Amici
Fake Or Not: Two Prerequisites For Jealousy, Juliane Bräuer, Federica Amici
Animal Sentience
Cook and colleagues (2018) use a novel approach to test jealousy in dogs. Although such a non-invasive approach is more than welcome in comparative research, several methodological shortcomings limit the impact of this study. We briefly outline two main problems. (1) There is no evidence that the fake dogs in the study were perceived as real, and thus as social rivals, which would be a prerequisite for jealousy. (2) It is questionable whether dogs generally show the cognitive prerequisites for jealousy, such as attentiveness toward a social rival, the ability to understand intentions, and a sense of fairness. We suggest …

Only The Human Brain Has The Cognitive Capacity For Jealousy, Donatella Marazziti
Animal Sentience
Jealousy is exclusively a human phenomenon because nonhuman animals lack the brain structures regulating the higher processes underlying jealousy.
Fill-In-The-Blank-Emotion In Dogs? Evidence From Brain Imaging, Alexandra Horowitz, Becca Franks, Jeff Sebo
Fill-In-The-Blank-Emotion In Dogs? Evidence From Brain Imaging, Alexandra Horowitz, Becca Franks, Jeff Sebo
Animal Sentience
What is needed to make meaningful claims about an animal’s capacity for subjective experience? Cook et al. (2018) attempt to study jealousy in dogs by placing them in a particular context and then seeing whether they display a particular brain state. We argue that this approach to studying jealousy falls short for two related reasons. First, the relationship between jealousy and the selected context is unclear. Second, the relationship between jealousy and the selected brain state (indeed, any single brain state) is unclear. These and other issues seriously limit what this study can show. It is important not to see …
The Degeneracy Of Behavior And The Rise Of Neuroimaging To Measure Affective States In Dogs, Peter F. Cook, Gregory S. Berns
The Degeneracy Of Behavior And The Rise Of Neuroimaging To Measure Affective States In Dogs, Peter F. Cook, Gregory S. Berns
Animal Sentience
It is gratifying and significant that so many scientists from diverse fields are arguing in-depth regarding a particularly complex set of social emotions in a non-human animal. Emotions play a fundamental role in decision making and information processing. Neuroimaging is important in understanding the cognitive and emotional worlds of non-human animals and can help measure covert emotions lacking clear behavioral correlates. Various experimental approaches could clarify the relative importance of attachment and aggression in jealousy and whether the phenomenon we measured is more akin to human envy or jealousy. Reverse inference from amygdala activation is probably justified because behavior is …
Sentience In Fishes: More On The Evidence, Michael L. Woodruff
Sentience In Fishes: More On The Evidence, Michael L. Woodruff
Animal Sentience
In my target article, I argued that the brains of ray-finned fishes of the teleost subclass (Actinopterygii) are sufficiently complex to support sentience — that these fishes have subjective awareness of interoceptive and exteroceptive sense experience. Extending previous theories centered on the tectum, I focused on the organization of the fish pallium. In this Response to the commentaries, I clarify that I do not propose that the fish pallium is, or must be, homologous to the mammalian neocortex to play a role in sentience. Some form of a functionalist approach to explaining the neural basis of sentience across taxa is …
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 …
Ecologies Of Embodied Minds Embedded: Radical Romantic Perspectives On Architectures Of Technology, Sharmaine Browne
Ecologies Of Embodied Minds Embedded: Radical Romantic Perspectives On Architectures Of Technology, Sharmaine Browne
Dissertations, Theses, and Capstone Projects
This dissertation explores Romantic responses to the role of architectural technologies in the development of material being, consciousness, and culture by applying a critical approach in which I combine radical embodied cognitive theory, ecocritical perspectives, and a phenomenological lens to select Romantic texts written from 1789 to 1884 in response to industrial modernity. While scholarship has thoroughly explored technology as a cultural force which inevitably shapes consciousness, I propose that a slight shift of emphasis from technology’s external influence to the material internalization of its influence allows for new perspectives—particularly in light of recent proposals in cognitive philosophy which assert …
Neuroscience, Materialism, And The Soul: Limit Questions, Jeremy M. Aymard
Neuroscience, Materialism, And The Soul: Limit Questions, Jeremy M. Aymard
Dialogue & Nexus
In light of recent discoveries in neuroscience linking the mind to physical processes, Christian philosophers have resorted to a more materialistic view of the human person, using neuroscience as support for their view that an immaterial soul does not exist. In this essay, I will point out a major flaw in the logic for defending a materialistic view, argue that either a bipartite or tripartite view of the human person is more aligned with Scripture, and hopefully point towards a more reliable means for attaining truth regarding human nature and the soul.
Mollifying Neuroscience And Christian Faith: An Emergent Monistic Claim For Free Will And The Soul, Paul Figel
Mollifying Neuroscience And Christian Faith: An Emergent Monistic Claim For Free Will And The Soul, Paul Figel
Dialogue & Nexus
Modern neuroscience makes it difficult for one to support a case for substance dualism regarding the existence of a soul and free will. The neuroscientific evidence stems from several experiments in which test subjects were instructed to perform a simple voluntary movement. Scientists consistently observed neurological antecedents preceding the subject’s conscious decision to perform the action. An examination of these experiments and the conclusions drawn will show several key inconsistencies that weaken the extreme anti-conscious will claim. However, it is important to not reject the neurological evidence against substance dualism, but instead discover a new perspective (e.g. emergent monism) that …

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.

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
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.

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
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, …

Is Psychological Science Committing “Suicide” By Linguistic Muddling?, Roger K. Thomas
Is Psychological Science Committing “Suicide” By Linguistic Muddling?, Roger K. Thomas
Animal Sentience
Beginning mainly with the “cognitive revolution” in psychology in the latter half of the 20th century, psychological science has been committing “suicide” slowly via linguistic muddling. Peña-Guzmán’s target article is but one of thousands of cuts contributing to this death by “suicide.” Having said that, given the current state of affairs in animal cognition research, there is much to commend in Peña-Guzmán’s article. I leave that to others, however. This commentary explains how the suicide by muddling of psychological science is happening in general, with the understanding that it applies also to Peña-Guzmán’s target article.

What would be the moral implications of the capacity for suicide in nonhuman animals? Humans can be helped to end their lives if they no longer find them bearable. Should captive animals not be given the same possibility?
Self, Death, And Suicide: Does An Animal Know Of These?, Carolyn A. Ristau
Self, Death, And Suicide: Does An Animal Know Of These?, Carolyn A. Ristau
Animal Sentience
Peña-Guzmán makes a strong case, using examples from the media and scientific literature, that many captive animals suffer severely. In examining the possibility of animal suicide, he dismisses the need for “reflective self-subjectivity” and “intent” in suicidal behavior. He claims that at least some animals understand “death,” citing examples of behavior he deems to be death “rituals.” But these can be more simply interpreted. The possibility of animal suicide remains more dubious than Peña-Guzmán suggests.
Changes In Behavior And Emotion Under Chicken Domestication, Martin Johnsson
Changes In Behavior And Emotion Under Chicken Domestication, Martin Johnsson
Animal Sentience
Marino’s target article provides an overview of chickens’ cognition, emotion, and personality, with the aim of changing how people view chickens. In this commentary, I will agree that chickens deserve better than their reputation, but contend with a statement about the lack of behavioral change under chicken domestication.
