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

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.

Scientific Advances And Moral Inertia, Kathie Jenni

Animal Sentience

Marino shows that chickens are as complex mentally as other birds and mammals. Yet common perceptions of chickens are slow to change in response to the science. Human capacities for willful ignorance, inattention, and avoidance keep us from learning about the animals we harm, and the inertia of habit and tradition keeps us from taking appropriate action in response to what we learn. It’s essential for teachers and activists to find ways to overcome this inattention and inertia.

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 20^th 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

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

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

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

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

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.

Flocks, Swarms, Crowds, And Societies: On The Scope And Limits Of Cognition, Zachariah A. Neemeh

Honors Undergraduate Theses

Traditionally, the concept of cognition has been tied to the brain or the nervous system. Recent work in various noncomputational cognitive sciences has enlarged the category of “cognitive phenomena” to include the organism and its environment, distributed cognition across networks of actors, and basic cellular functions. The meaning, scope, and limits of ‘cognition’ are no longer clear or well-defined. In order to properly delimit the purview of the cognitive sciences, there is a strong need for a clarification of the definition of cognition. This paper will consider the outer bounds of that definition. Not all cognitive behaviors of a given …

Cognitive And Emotional Processes Involved In The Experience Of Objects As Holy Or Transcendent, Lotte J. Pummerer

College of Graduate Studies: Theses & Dissertations

In recent years, attitudes about religion/spirituality have become more pluralistic (Pew Research Center, 2015a). At the same time, the number of individuals who identify themselves as nonreligious, atheist or agnostic are growing (Pew Research Center, 2015b), yet we are lacking words and research to describe their attributions of transcendence in language not bound to religious concepts. This study aims at examining both concepts – holiness and transcendence – in their similarities and differences through assessing cognitive and emotional processes involved in experiences of objects.

The study consisted of two parts with a total of 206 Christian and 52 nonreligious/atheistic/agnostic participants. …

On Supposing, Imagining, And Resisting, Eric M. Peterson

Theses and Dissertations--Philosophy

My research focuses on the philosophy of imagination. Within the analytic tradition, there recently has been a growing interest in imagination. The current research lies at the crossroads of various sub-disciplines of philosophy, including aesthetics, moral psychology, ethics, epistemology, and philosophy of mind. My work joins this choir as a voice from within philosophy of mind.

My dissertation addresses two questions within philosophy of imagination. What I call the Relation Question asks what is the proper relation between supposition and imagination, and what I call the Unification Question asks what is the imagination. With regards to the Relation Question, …

Real Intentions And Virtual Wrongs, Elaine Sohng

CMC Senior Theses

In this thesis, I answer the gamer's dilemma or the inability to find a moral distinction between virtual pedophilia and virtual murder. I expand virtual pedophilia to virtual rape to address increasing rates of sexual harassment and assault in virtual reality. In this thesis, I 1) explain what occurs when one engages in virtual rape; 2) identify relevant moral differences between physical rape and virtual rape; 3) challenge the existing relationship between committing harm and wrong in the case of rape; and 4) argue that virtual rape is morally reprehensible due to the agent’s intention to utilize a person as …

Recovery From Design, Cassandra J. Ellison

Theses and Dissertations

Through research, inquiry, and an evaluation of Recovery By Design, a ‘design therapy’ program that serves people with mental illness, substance use disorders, and developmental disabilities, it is my assertion that the practice of design has therapeutic potential and can aid in the process of recovery. To the novice, the practices of conception, shaping form, and praxis have empowering benefit especially when guided by Conditional and Transformation Design methods together with an emphasis on materiality and vernacular form.

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

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.

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 …

Animal Sentience And The Precautionary Principle, Jonathan Birch

Animal Sentience

In debates about animal sentience, the precautionary principle is often invoked. The idea is that when the evidence of sentience is inconclusive, we should “give the animal the benefit of the doubt” or “err on the side of caution” in formulating animal protection legislation. Yet there remains confusion as to whether it is appropriate to apply the precautionary principle in this context, and, if so, what “applying the precautionary principle” means in practice regarding the burden of proof for animal sentience. Here I construct a version of the precautionary principle tailored to the question of animal sentience together with a …

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.

What Harmful Practices? The Material Scope Of Animal Protection Legislation, Eze Paez

Animal Sentience

Jonathan Birch proposes a criterion for the subjective scope of animal protection legislation. He says nothing about its material scope: which harmful practices it should regulate. I argue, first, that most moral views would agree that the worst forms of animal exploitation should be legally forbidden, even if there will inevitably be disagreement about some cases of animal experimentation. I also argue that, when feasible, there should be legal provisions to help wild animals.

The Value Of Bayesian Statistics For Assessing Credible Evidence Of Animal Sentience, Anil K. Seth, Zoltan Dienes

Animal Sentience

Determining what constitutes practically relevant, statistically significant evidence for animal sentience, under the precautionary principle, could be enhanced through Bayesian statistics. A Bayesian approach allows the incorporation of multiple evidence sources through prior probabilities, the tracking of changing evidence across time, and a principled means of adjusting evidentiary bars via Bayes factors.

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.

Anecdotes Can Be Evidence Too, Heather Browning

Animal Sentience

Birch’s criterion for the precautionary principle imposes a high evidential standard that many cases will fail to meet. Reliable, relevant anecdotal evidence suggestive of animal sentience should also to fall within the scope of the precautionary principle. This would minimize potential suffering (as happened in the case cephalopods) while further evidence is gathered.

Animal Pain And The Social Role Of Science, Leslie Irvine

Animal Sentience

Assuming that all animals are sentient would mean ending their use in most scientific research. This does not necessarily imply an unscientific or anti-scientific stance. Examining the social role of science reveals its considerable investment in preserving the status quo, including the continued use of animal subjects. From this perspective, the use of animal subjects is a custom that science could move beyond, rather than a methodological requirement that it must defend.

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.

Choice-Induced Preference: A Challenge For Contrast, Benjamin R. Eisenreich, Benjamin Y. Hayden

Animal Sentience

In his target article, Zentall asks: “to experience cognitive dissonance is it necessary for one to have conflicting beliefs or even beliefs at all?” He then argues that a simple behavioral process, the Within Trial Contrast Effect, may be sufficient to explain observed cognitive dissonance effects in nonhuman animals and possibly humans as well. We agree with Zentall that this effect is sufficient to explain many reported cognitive dissonance effects in nonhuman animals, but question its sufficiency for primate behavior (both monkeys and humans).

Reductionism And Accounts Of Cognitive Dissonance, Kent D. Bodily

Animal Sentience

Zentall (2016) proposed within-trial contrast as an alternative account of cognitive dissonance with greater parsimony and generalizability between human and nonhuman species. This commentary describes forms of reductionism, categorizes several competing accounts of cognitive dissonance phenomena, and addresses the strengths and weaknesses according to the reductionist form each account takes. A focus on functional relations may make explanation more parsimonious while bridging theoretical divides between human and nonhuman research programs.

A Risk Assessment And Phylogenetic Approach, Culum Brown

Animal Sentience

The precautionary principal is often invoked when talking about the evidence of sentience in animals, largely because we can never be certain what any animal is thinking or feeling. Birch (2017) offers a preliminary framework for the use of the precautionary principal for animal sentience combining an epistemic rule with a decision rule. I extend this framework by adding an evolutionary phylogentic approach which spreads the burden of proof across broad taxonomic groups and a risk assessment component which magnifies the likely impact by the number of animals involved.

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.
