To Identify All The Relevant Factors Is To Explain Feeling, Arthur S. Reber Jan 2017

To Identify All The Relevant Factors Is To Explain Feeling, Arthur S. Reber

Animal Sentience

Several additional comments on Reber (2016a) have appeared. Like those addressed in Reber (2016b), they reflect points of agreement and disagreement on various elements of my Cellular Basis of Consciousness (CBC) model. Some, however, seem to have missed key points. I'm willing to take some responsibility for this. Perhaps I was not clear about some of the more radical points of the model. Hopefully the case-by-case review here will help.


Consciousness Is Not Inherent In But Emergent From Life, Jon Mallatt, Todd E. Feinberg Jan 2017

Consciousness Is Not Inherent In But Emergent From Life, Jon Mallatt, Todd E. Feinberg

Animal Sentience

Reber’s theory of the cellular basis of consciousness (CBC) is right to emphasize that we should study consciousness (sentience) in its simplest form, taking its evolution into account. However, not enough evidence is presented to support CBC’s unorthodox claim that even simple, one-celled organisms are conscious. As pointed out by other commentators, the CBC seems to be based on outdated ideas about evolution and does not acknowledge that consciousness could be an evolutionary novel feature. Such emergent features are abundant in living organisms. We review our own emergentist solution, in which consciousness evolved in the elaborating nervous systems of the …


What Can Research On Nonhumans Tell Us About Human Dissonance?, Jennifer Vonk Jan 2017

What Can Research On Nonhumans Tell Us About Human Dissonance?, Jennifer Vonk

Animal Sentience

Zentall’s thoughtful review of the literature on cognitive dissonance in nonhumans helps to highlight the common finding that similar outcomes in humans and nonhumans can be attributed to different underlying mechanisms. I advocate a more fully comparative approach to the underlying mechanisms, avoiding the assumption of shared processes in humans and nonhumans.


Dissonance Reduction In Nonhuman Animals: Implications For Cognitive Dissonance Theory, Cindy Harmon-Jones, Nick Haslam, Brock Bastian Jan 2017

Dissonance Reduction In Nonhuman Animals: Implications For Cognitive Dissonance Theory, Cindy Harmon-Jones, Nick Haslam, Brock Bastian

Animal Sentience

We review the evidence for dissonance reduction in nonhuman animals and examine the alternative explanations for these effects. If nonhuman animals engage in dissonance reduction, this supports the original theory as proposed by Festinger (1957) over the revisions to the theory that focused on the self-concept. Evidence of animal sentience, including dissonance reduction, may be a source of cognitive dissonance.


Clarifying Concepts In Cognitive Dissonance Theory, Eddie Harmon-Jones Jan 2017

Clarifying Concepts In Cognitive Dissonance Theory, Eddie Harmon-Jones

Animal Sentience

This commentary on Zentall’s target article focuses primarily on clarifying some postulates and variables in cognitive dissonance theory. I discuss the adaptive motivational functions of dissonance arousal and dissonance reduction, and attempt to clarify some past dissonance experiments and to tease apart a dissonance theory and contrast explanation of effort-justification-type effects. The evidence and arguments reviewed here support the explanatory power of cognitive dissonance theory in a wide variety of circumstances in human and nonhuman animals, but they depend on first defining concepts such as “cognitions” quite broadly, as Festinger did when he originally proposed the theory.


Cognitive Dissonance Or Contrast? It Could Be Both, Thomas Zentall Jan 2017

Cognitive Dissonance Or Contrast? It Could Be Both, Thomas Zentall

Animal Sentience

My target article suggested that cognitive dissonance may be accounted for by a simpler mechanism: contrast. Whether contrast can explain all cognitive dissonance effects is an empirical question, but it is always useful to try to distinguish simpler mechanisms from more complex cognitive ones. The insistence that cognitive dissonance is a human-only process quite different from contrast may be a self-serving means of justifying the exploitation of animals.


Cognitive Continuity In Cognitive Dissonance, David R. Brodbeck, Madeleine I. R. Brodbeck Jan 2017

Cognitive Continuity In Cognitive Dissonance, David R. Brodbeck, Madeleine I. R. Brodbeck

Animal Sentience

Zentall’s (2016) model of cognitive dissonance is compatible with cognitive continuity between humans and nonhumans. It may help explain cognitive dissonance-like behavior in many species, including humans. It is also consistent with Tinbergen’s (1963) ‘four whys’ in ethological explanation.


Fishes Are Gaining Academic Respect, Jonathan Balcombe Jan 2017

Fishes Are Gaining Academic Respect, Jonathan Balcombe

Animal Sentience

I respond to five commentaries on my 2016 book What a Fish Knows. The commentaries express more harmony than dissent about my interpretation of fishes as cognitive, aware individuals deserving better treatment by humankind.


Consciousness, Evidence, And Moral Standing, Irina Mikhalevich Jan 2017

Consciousness, Evidence, And Moral Standing, Irina Mikhalevich

Animal Sentience

Woodruff (2017) claims to have identified the neural correlates of phenomenal consciousness (“p-consciousness”) in fishes, and argues that these neurological data, along with behavioral evidence, suggest that teleost fishes are in all probability sentient organisms. Woodruff’s case may be strengthened by challenging key assumptions behind a common criticism of accounts such as his: that fishes cannot be p-conscious because they lack the cortical structures necessary for p-consciousness. A more serious objection to Woodruff’s proposal would be that his evidence for p-consciousness establishes only that fishes are “access-conscious” (“a-conscious”), where a-conscious states are cognitive representations that are made available to cognitive …


Battlefish Contention, Sean Allen-Hermanson Jan 2017

Battlefish Contention, Sean Allen-Hermanson

Animal Sentience

Contrary to Woodruff’s suggestion, investigations into possible reasoning capacities of cichlid fighting fish and trace memory in goldfish do not support claims about sentience. This is disputed by research results about learning and implicit processing, sleep, vegetative states, amnesia, semantic priming, artificial network modeling, and even insects. A novel, deflationary, interpretation of Grosenick et al.'s experiments on A. burtoni is also offered.


Sentience In Living Tissue, Alfredo Pereira Jr. Jan 2017

Sentience In Living Tissue, Alfredo Pereira Jr.

Animal Sentience

I agree with Woodruff’s concept of sentience but must disagree about what he proposes as the biological correlates of feeling. Based on the interpretation of brain function originally presented by Camilo Golgi, I assume that feelings are instantiated by hydro-ionic waves in living tissue. From this viewpoint, the anatomical, physiological and behavioural criteria of Woodruff would not be necessary to argue for sentience in fish.


Of Cortex And Consciousness: “Phenomenal,” “Access,” Or Otherwise, Scott A. Husband Jan 2017

Of Cortex And Consciousness: “Phenomenal,” “Access,” Or Otherwise, Scott A. Husband

Animal Sentience

From the perspective of a comparative neuroanatomist studying the avian pallium, Woodruff’s (2017) claims about the behavioral and electrophysiological evidence for teleost sentience blur the lines between phenomenal and access consciousness (Block, 1995). I discuss the bias that complex cognition can only arise in the cortical layering typical of the mammalian pallium and conclude that Woodruff makes a good case that the tecto-pallial connections in teleosts are sufficiently complex to support something like sentience.


Learning, Memory, Cognition, And The Question Of Sentience In Fish, Robert Gerlai Jan 2017

Learning, Memory, Cognition, And The Question Of Sentience In Fish, Robert Gerlai

Animal Sentience

Evolutionarily conserved features have been demonstrated at many levels of biological organization across a variety of species. Evolutionary conservation may apply to complex behavioral phenomena too. It is thus not inconceivable that a form of sentience does exist even in the lowest order vertebrate taxon, the teleosts. How similar it is to human sentience in its level of complexity or in its multidimensional features is a difficult question, especially from an experimental standpoint, given that even the definition of human sentience is debated. Woodruff attempts a Turing-like test of fish sentience, and lists numerous neuroanatomic, neurophysiological and behavioral similarities between …


Animal Models, Agendas And Sentience, Thomas Creson Jan 2017

Animal Models, Agendas And Sentience, Thomas Creson

Animal Sentience

Woodruff’s target article on teleost consciousness is a well-organized logical argument for considering the fish as a sentient being. This becomes more important for animal ethical discussion as the fish becomes a more important and legitimate animal model for investigating animal states and traits associated with higher levels of behavior such as learning and memory.


We Still Need A Theory, Paula Droege Jan 2017

We Still Need A Theory, Paula Droege

Animal Sentience

Woodruff (2017) has compiled a convincing array of data to support his contention that teleost fish feel pain. However, in the absence of an explanatory theory about the nature and function of consciousness, a checklist of criteria is insufficient to allay skeptical concerns. I offer a theory that can explain why features like selective attention and behavioral flexibility indicate consciousness. Consciousness represents the present moment in order to allow dynamic changes in actions or goals in response to situational demands.


Dogs Consciously Experience Emotions: The Question Is, Which?, Ralph Adolphs Jan 2017

Dogs Consciously Experience Emotions: The Question Is, Which?, Ralph Adolphs

Animal Sentience

I discuss three themes related to Kujala’s target article. First, the wealth of emerging data on cognitive studies in dogs will surely show that dogs have a very rich repertoire of cognitive processes, for most of which we find homologues in humans. Second, understanding the internal states that mediate social behaviors, such as emotions, requires us to consider both a dog’s behaviors with other dogs, and the emergence of new behavioral patterns in interaction with humans. Third, all of this will certainly narrow the range of justifications for denying that dogs have subjective experiences of emotions.


Direct Perception Of Animal Mind, Paul Morris Jan 2017

Direct Perception Of Animal Mind, Paul Morris

Animal Sentience

Kujala’s (2017) target article is ostensibly focused on how everyday folk (fail to) make sense of canine emotions. However, the theories outlined in the article apply to making sense of all aspects of the mentality of both human and non-human animals. The target article neglects the fundamental arguments surrounding the problem of other minds. I explore the relevant arguments and briefly review approaches suggesting that our everyday-life sense that both human and non-human animals are thinking, feeling, emotional beings has a secure epistemological basis.


Canine Emotions And The Bond Between Humans And Dogs, Robert G. Franklin Jr. Jan 2017

Canine Emotions And The Bond Between Humans And Dogs, Robert G. Franklin Jr.

Animal Sentience

I explore how the findings reviewed by Kujala (2017) influence our understanding of the human-dog bond. The special social cognitive abilities of dogs may be unique among animal species, probably influenced by the circumstances surrounding canine domestication. The bond has influenced animal welfare policies, giving dogs a privileged place among animals. To determine what protections other species should have in a rational animal welfare policy, more research is needed on whether other species have similar social cognitive abilities.


Communicating Canine And Human Emotions, Juliane Bräuer, Karine Silva, Stefan R. Schweinberger Jan 2017

Communicating Canine And Human Emotions, Juliane Bräuer, Karine Silva, Stefan R. Schweinberger

Animal Sentience

Kujala (2017) reviews a topic of major relevance for the understanding of the special dog-human relationship: canine emotions (as seen through human social cognition). This commentary draws attention to the communication of emotions within such a particular social context. It highlights challenges that need to be tackled to further advance research on emotional communication, and it calls for new avenues of research. Efforts to disentangle emotional processes from cognitive functioning might be necessary to better comprehend how they contribute, alone and/or in combination, to the communication of emotions. Also, new research methods need to be developed to account for the …


Studying Dog Emotion Beyond Expression And Without Concern For Feeling, Peter F. Cook Jan 2017

Studying Dog Emotion Beyond Expression And Without Concern For Feeling, Peter F. Cook

Animal Sentience

Studies of dog emotion have focused on the expression of social emotion, either because this is taken to suggest human-like feeling states in dogs or because it has been the most accessible signal of dog emotional processing. I argue for an approach grounded in affective neuroscience, relying on direct measures of physiology across different contexts. This work may be particularly fertile in exploring social emotion in the dog, not because dogs necessarily share human emotional states, but because they are unique in having likely evolved to fit a human social niche.


Inferring Emotion Without Language: Comparing Canines And Prelinguistic Infants, Stefanie Hoehl Jan 2017

Inferring Emotion Without Language: Comparing Canines And Prelinguistic Infants, Stefanie Hoehl

Animal Sentience

Research on canine emotions has to deal with challenges quite similar to psychological research on social and emotional development in human infants. In both cases, verbal reports are unattainable, and behavioral and physiological methods have to be adjusted to the specific population. I will argue that both regarding empirical approaches and conceptual work, advances in research on social-cognitive development in human infants can inform the study of canine emotions.


Reef Society And The Tyranny Of Data, Robert Wintner Dec 2016

Reef Society And The Tyranny Of Data, Robert Wintner

Animal Sentience

Modern science now approaches divergent processes in many areas, including health assessments of marine eco-systems and social aspects of marine species. Scientific data have long enjoyed a reputation for objectivity but incidents of science-for-hire, data spinning/skewing and political jading are more frequent than ever. In the field of reef creature sensitivity, technical treatises can “logically” explain away what a person of average education can clearly observe on any given reef. Western medicine discounted anecdotal evidence of any cure outside the 4% margin of error until those cures demanded attention and in some cases application. Modern science must now enter an …


Still Wondering How Flesh Can Feel, Gwen J. Broude Dec 2016

Still Wondering How Flesh Can Feel, Gwen J. Broude

Animal Sentience

Reber believes he has simplified Chalmers’s “hard problem” of consciousness by arguing that subjectivity is an inherent feature of biological forms. His argument rests on the related notions of continuity of mind and gradual accretion of capacities across evolutionary time. These notions need to be defended, not just asserted. Because Reber minimizes the differences in mental faculties among species across evolutionary time, it becomes easier to assert, and perhaps believe, that sentience is already present in early biological forms. The more explicit we are about the differences among these mental faculties and the differences across species, the less persuasive is …


Animals Aren’T Persons, But Is It Time For A Neologism?, Helen Steward Dec 2016

Animals Aren’T Persons, But Is It Time For A Neologism?, Helen Steward

Animal Sentience

Mark Rowlands argues that at least some animals are persons, based on the idea that (i) many animals have a property he calls “pre-reflective awareness,” (ii) the capacity for pre-reflective awareness is sufficient to satisfy the traditional Lockean definition of personhood, and (iii) satisfaction of the traditional Lockean definition of personhood is sufficient for being a person. I agree with (i) and can see that there is a persuasive case for (ii), but I think the case against (iii) blocks the conclusion that animals are persons. I suggest that we may need instead to coin a neologism in order to …


Reber’S Caterpillar Offers No Help, Carl Safina Dec 2016

Reber’S Caterpillar Offers No Help, Carl Safina

Animal Sentience

Reber’s target article “Caterpillars, consciousness and the origins of mind” seems only to shift but not to address the question of where the mind is and how minds occur.



Insect Consciousness: Commitments, Conflicts And Consequences, Colin Klein, Andrew B. Barron Nov 2016

Insect Consciousness: Commitments, Conflicts And Consequences, Colin Klein, Andrew B. Barron

Animal Sentience

Our target article, “Insects have the capacity for subjective experience,” has provoked a diverse range of commentaries. In this response we have collated what we see as the major themes of the discussion. It is clear that we differ from some commentators in our commitments to what subjective experience is and what the midbrain is capable of. Here we clarify where we stand on those points and how our view differs from some other influential perspectives. The commentaries have highlighted the most lively areas of disagreement. We revisit here the debates surrounding whether the cortex is essential for any form …


Consciousness And Evolutionary Biology, Yew-Kwang Ng Nov 2016

Consciousness And Evolutionary Biology, Yew-Kwang Ng

Animal Sentience

Reber’s axiom: “Any organism with flexible cell walls, a sensitivity to its surrounds and the capacity for locomotion will possess the biological foundations of mind and consciousness” does not seem to be supported by things we know and the logic of evolutionary biology. The latter leads to the conclusion that conscious species are flexible in their behavior (rather than in their cell walls), as argued in Ng (1995, 2016). Locomotion may be completely hard-wired and need not involve consciousness. It is hard enough to explain how consciousness could emerge in a sophisticated brain: Isn’t it a harder problem to show …


The Difference Between Conscious And Unconscious Brain Circuits, Ezequiel Morsella, Zaviera Reyes Nov 2016

The Difference Between Conscious And Unconscious Brain Circuits, Ezequiel Morsella, Zaviera Reyes

Animal Sentience

Theoretical frameworks in which consciousness is an inherent property of the neuron must account for the contrast between conscious and unconscious processes in the brain and address how neural events can ever be unconscious if consciousness is a property of all neurons. Other approaches have sought answers regarding consciousness by contrasting conscious and unconscious processes and through investigating the complex interactions between the two kinds of processes, as occurs most notably in human voluntary action. In voluntary action, consciousness is associated most, not with motor control or low-level perceptual processing, but with the stage of processing known as action selection.



Resolving The Hard Problem And Calling For A Small Miracle, Arthur S. Reber Nov 2016

Resolving The Hard Problem And Calling For A Small Miracle, Arthur S. Reber

Animal Sentience

With the exception of the commentary by Key, the commentaries on Reber have a common feature: the commenters feel, with varying levels of enthusiasm, that there is at least some virtue in the core assumption of the Cellular Basis of Consciousness (CBC) theory that consciousness (or subjectivity or sentience) accompanies the earliest forms of life. The model has two important entailments: (a) it resolves the (in)famous Hard Problem by redirecting the search for the biochemical foundations of sentience away from human consciousness; and (b) it reduces the need for an emergentist miracle to a far simpler scale than is currently …


Unconscious Higher-Order Thoughts (Hots) As Pre-Reflective Self-Awareness?, Rocco J. Gennaro Nov 2016

Unconscious Higher-Order Thoughts (Hots) As Pre-Reflective Self-Awareness?, Rocco J. Gennaro

Animal Sentience

Rowlands argues that many nonhuman animals are “persons,” contrary to the prevailing orthodoxy which rests on a mistaken conception of the kind of self-awareness relevant to personhood. He argues that self-awareness bifurcates into two importantly different forms — reflective self-awareness and pre-reflective self-awareness — and that many animals can have the latter, which is sufficient for personhood. I agree that there is good reason to think that many animals can have pre-reflective self-awareness, but I think Rowlands is mistaken about its nature. His account runs the risk of leading to an infinite regress objection, and his notion of pre-reflective self-awareness …
