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, …


Misperceiving And Underestimating The Ubiquitous Chicken, Carrie P. Freeman Jan 2017

Misperceiving And Underestimating The Ubiquitous Chicken, Carrie P. Freeman

Animal Sentience

Marino has provided an accurate and nuanced view about chickens’ complex capabilities as sentient individuals. I explore the implications of these findings for scholars as well as for activists in the protection of farmed animals.


Is Psychological Science Committing “Suicide” By Linguistic Muddling?, Roger K. Thomas Jan 2017

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.


On Assisted Suicide, Clark Glymour Jan 2017

On Assisted Suicide, Clark Glymour

Animal Sentience

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 Jan 2017

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 Jan 2017

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.


Experiment Versus Analogy In The Search For Animal Sentience, Geoffrey Hall Jan 2017

Experiment Versus Analogy In The Search For Animal Sentience, Geoffrey Hall

Animal Sentience

Deciding between rival accounts of an instance of an animal’s behavior can frequently be achieved by experimental tests of different predictions made by the alternatives. When, however, one (or both) of the alternatives is expressed in terms of the mental state of the animal, an experimental test to distinguish them can be hard to find. Although it is unsatisfactory in many ways, it may be necessary to fall back on argument from analogy with human behavior and experience.


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.


Establishing That Contrast Is Cognitive Dissonance, Travis R. Smith Jan 2017

Establishing That Contrast Is Cognitive Dissonance, Travis R. Smith

Animal Sentience

Zentall suggests that the same mechanism underlies cognitive dissonance in humans and the within-trial contrast effect in pigeons (and humans). The contrast effect has face validity in explaining cognitive dissonance, but more research is needed to establish construct validity. To determine whether both phenomena share the same mechanism, future research should test (1) whether both share physiological processes, (2) whether individuals who show sensitivity to one are also sensitive to the other, and (3) whether both phenomena are affected by the same changes in an independent variable.


How Should We Conceptualize Moral Disagreements About Animals?, Kristian Cantens Jan 2017

How Should We Conceptualize Moral Disagreements About Animals?, Kristian Cantens

Graduate Student Theses, Dissertations, & Professional Papers

I intend this paper as a sort of philosophical reflection on my experiences as an animal activist. In my three years of doing outreach on college campuses, I came to an increasing appreciation for what Murdoch referred to as “the difficulty and complexity of the moral life and the opacity of persons” (Murdoch 1998d, 293). This appreciation came in turn at the cost of an increasing disappointment with many of the philosophers I admired at the time – namely, Peter Singer and Tom Regan. What I came to understand is that many of these contemporary moral theories were in fact …


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 …

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.


The Potential For Sentience In Fishes, Jay R. Stauffer Jr. Jan 2017

The Potential For Sentience In Fishes, Jay R. Stauffer Jr.

Animal Sentience

Balcombe’s book is filled with information on the biology, behavior, and life history of fishes. I do not agree with all his premises. I am still somewhat perplexed about the discussion of whether fish feel pain; I am not sure whether the distinction between nociception and pain makes any difference. Overall, however, his treatment of the principles of both natural and sexual selection is comprehensive and accurate, and has greatly increased my knowledge and awareness of the biology, ethology, and potential for sentience in fishes. In summary, this work has exposed me to new ideas about how to examine fishes …


The “Precautionary Principle” – A Work In Progress, Shelley Adamo Jan 2017

The “Precautionary Principle” – A Work In Progress, Shelley Adamo

Animal Sentience

The target article by Birch illustrates the practical difficulties with the “Animal Sentience Precautionary Principle” (ASPP) while presenting potential solutions. However, the ASPP will be difficult to use without guidelines detailing how evidence of sentience should be assessed. Moreover, extrapolating conclusions found for a single species to all species within an Order is problematic. Finally, I recommend that Birch demonstrate his ASPP framework using a controversial test case to help show how it could be used in real-world situations.


Shoring Up The Precautionary Bar, Jon Mallatt Jan 2017

Shoring Up The Precautionary Bar, Jon Mallatt

Animal Sentience

I offer four ways to reinforce Birch’s precautionary principle so it can be used effectively and practically in deciding which animals to cover by legislation for humane treatment: (1) add one more credible indicator of sentience to the BAR rule; (2) use phylogenetic classification, not the outdated Linnaean classification, to test which animal clades have sentience; (3) disentangle the pain of suffering from sentience; and (4) reconsider the sentient status of decapods and insects to remove potential inconsistencies in the proposed framework.


Precaution, Proportionality And Proper Commitments, Colin Klein Jan 2017

Precaution, Proportionality And Proper Commitments, Colin Klein

Animal Sentience

Birch’s extension of the precautionary principle (PP) is plausible but raises issues about how proportionality ought to be incorporated into law. Following Steel (2013), I suggest that the PP is best considered as a meta-norm, and as such any resulting laws are likely to lack the fineness of grain that we would hope to achieve. To fill the gap, I suggest a parallel with the ethics of studying looted artifacts.
