Fish Sentience, Consciousness, And Ai, Ila France Porcher Jan 2018

Fish Sentience, Consciousness, And Ai, Ila France Porcher

Animal Sentience

The systematic criticism of articles providing evidence that fish and invertebrates can feel pain is discussed. Beliefs are known to be stronger than evidence in the human mind, and could generate this outcry, while from another perspective, the criticisms appear as a territorial move by fishermen against a perceived threat to their domain. The scientific inconsistency in which consciousness is granted to machines but not to fish and invertebrates, purely due to political bias, is pointed out. No basis exists for denying sentience to any life form as long as science is ignorant of the nature and source of consciousness.


Degrees Of Sentience?, Jonathan Birch Jan 2018

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.


Time To (Finally) Acknowledge That Fish Have Emotionality And Pain, Konstantin A. Demin, Anton M. Lakstygal, Allan V. Kalueff Jan 2018

Time To (Finally) Acknowledge That Fish Have Emotionality And Pain, Konstantin A. Demin, Anton M. Lakstygal, Allan V. Kalueff

Animal Sentience

The increasing work using fish as a model organism calls for a better understanding of their sentience. While growing evidence suggests that pain and emotionality exist in zebrafish, many deniers continue to ignore the evidence. Here we revisit the main conceptual breakthroughs in the field that argue clearly for pain and emotionality. We call for an end to denial and a focus on studying the mechanisms of fish pain and emotionality, and their translational relevance to human conditions.


Jealousy In Dogs? Evidence From Brain Imaging, Peter Cook, Ashley Prichard, Mark Spivak, Gregory S. Berns Jan 2018

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 Jan 2018

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 Jan 2018

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 Jan 2018

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 Jan 2018

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 Jan 2018

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 Jan 2018

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 Sep 2017

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 Sep 2017

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 Jun 2017

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.


Down Syndrome, The Image Of God, And Personhood, Paris Webb May 2017

Down Syndrome, The Image Of God, And Personhood, Paris Webb

Dialogue & Nexus

People with Down syndrome help Christians understand what being made in the image of God truly means. After describing Down syndrome, we will examine the different views of the image of God and how these relate to people with Down syndrome. Another approach will be to define personhood in light of God’s image and relate it to Down syndrome. We will use the principles held by the L’Arche community as an exemplar in this discussion to demonstrate that those with Down syndrome encourage us to expand our understanding of the image of God. Consequently, Down’s persons allow us to apply …


Mollifying Neuroscience And Christian Faith: An Emergent Monistic Claim For Free Will And The Soul, Paul Figel May 2017

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 …

Raising Consciousness About Chicken Consciousness, Bernard Rollin Jan 2017

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 Jan 2017

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 Jan 2017

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 Jan 2017

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 Jan 2017

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.


What Is The Pressing “Animal Question” About? Thinking/Feeling Capacity Or Exploitability?, Gordon Hodson Jan 2017

What Is The Pressing “Animal Question” About? Thinking/Feeling Capacity Or Exploitability?, Gordon Hodson

Animal Sentience

Marino’s timely review highlights what humans go to great lengths to ignore and suppress: non-human animals such as chickens have rich inner lives. Although I share her belief that such evidence should provide the impetus for ending the exploitation of chickens, the psychological literatures on motivated reasoning and group-based dominance suggest not only that this is unlikely but that people will push back precisely because of the implications (as they do for climate change). Human psychology has done a great deal to suppress the recognition of sentience in animals, but it can also shed insights into ending exploitation.


Non-Human Animal Suicide Could Be Tested, David Lester Jan 2017

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 Jan 2017

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 Jan 2017

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 Jan 2017

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.

Getting To The Other Side, Debra Merskin Jan 2017

Getting To The Other Side, Debra Merskin

Animal Sentience

Marino’s comprehensive, detailed, and timely review provides clear evidence of the sentience of chickens and strong support for those wishing to challenge their exclusion from even the limited protections currently accorded to animals grown for food.



Sentience Does Not Require “Higher” Cognition, Giorgio Vallortigara Jan 2017

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, …
