Making Emotions Trustworthy, Xiaoyu Ke
Making Emotions Trustworthy, Xiaoyu Ke
Arts & Sciences Graduate Student Theses and Dissertations
I investigate ways by which agents can make their emotions more trustworthy from a perspective that’s informed by recent psychological research on the nature of emotion regulation. This dissertation is a collection of three articles, each addressing one type of cases of untrustworthy emotions in a particular context. Chapter one (Developing Appropriate Emotions) concerns emotions that are untrustworthy because they are irrelevant to the moral or epistemic judgements at hand. By situating the problem in the context of a situationist challenge to neo-Aristotelian virtue ethics, I argue that we can address this problem by developing ameliorative abilities such as emotion …
Psychophysiological Effects Of Increasing Awareness Of Nondual Consciousness In Young Adults With Depression And Anxiety, Milena Braticevic
Psychophysiological Effects Of Increasing Awareness Of Nondual Consciousness In Young Adults With Depression And Anxiety, Milena Braticevic
CONSCIOUSNESS: Ideas and Research for the Twenty-First Century
Young adults increasingly suffer from anxiety and depression during the time of transition into adulthood. This research study examined the effects of increasing awareness of nondual consciousness in young adults who were experiencing various levels of anxiety and depression. The methodology was mixed-method and included four 1-hour group-based sessions over 4 weeks. Increasing awareness of nondual consciousness through educational, experiential, and behavioural components resulted in reduction in the average depression score from 19.4 (borderline clinical depression) to 10 (normal), and reduction in the average anxiety score from 12.7 (moderate anxiety) to 6.9 (mild). Participants reported increased mental, emotional, physical, and …
Belonging Amidst Bias: Embracing Difference On The Path To Common Humanity, Alyssia Sheikh
Belonging Amidst Bias: Embracing Difference On The Path To Common Humanity, Alyssia Sheikh
Mindfulness Studies Theses
The mindfulness community prioritizes self-awareness and common humanity, but is often entrapped by the idea that oneness is equivalent to sameness. This inclination for objectivity is rooted in the same neural propensities that facilitate bias; the brain is a subjective organ, however, and so neurologically speaking, bias is inevitable. This paper asks: Is striving for sameness separating us from interconnectedness? A human experience is a subjective, diverse, and variable one. The path to shared humanity and social justice co-occurs with increasing cultural humility through mindful awareness and acknowledging our subjective nature. Exploring our neurological tendency to make assumptions, we …
Hiding Behind The Title: Bridging The Gap Between Identity And Leadership Through Neuroscience, Emotional Intelligence And Ethical Management, Alicia S. Huddleston
Hiding Behind The Title: Bridging The Gap Between Identity And Leadership Through Neuroscience, Emotional Intelligence And Ethical Management, Alicia S. Huddleston
College of Education Theses and Dissertations
Leadership is the key determinant in the success of any organization, and leaders have an immeasurable impact on the lives and performances of those they have been entrusted to develop, support and lead. School principals are an integral part of the leadership tapestry within society and many people have been impacted by a school principal. Often enough, there are individuals who lead with or behind their title versus understanding first who they are intrinsically, and then working through those dynamics to effectively lead their own lives. When leaders are able to do this, then and only then are they equipped …
Pain Sentience Criteria And Their Grading, Eva Jablonka, Simona Ginsburg
Pain Sentience Criteria And Their Grading, Eva Jablonka, Simona Ginsburg
Animal Sentience
On the basis of the target article by Crump and colleagues, we suggest a more parsimonious scheme for evaluating the evidence for sentience. Since some of the criteria used by Crump et al. are not independent and some are uninformative we exclude some criteria and amalgamate others. We propose that evidence of flexible learning and prioritization, in conjunction with relevant data on brain organization, is sufficient for assigning pain-sentience to an animal and we suggest a scoring scheme based on four criteria.
Truly Minimal Criteria For Animal Sentience, Mark Solms
Truly Minimal Criteria For Animal Sentience, Mark Solms
Animal Sentience
The criteria for determining animal sentience proposed in the target article are sensible but they lack an explicit functional justification for the focus on pain. This commentary provides an abbreviated account of the most basic functional principles that underpin animal sentience and articulates some minimal criteria for determining its presence.
No Need For Certainty In Animal Sentience, Yew Kwang Ng
No Need For Certainty In Animal Sentience, Yew Kwang Ng
Animal Sentience
This commentary supports Crump et al.’s (2022) point that where risks to welfare are severe, strong evidence of sentience is sufficient to warrant protecting welfare. Crump et al.’s eight criteria for sentience are also useful. Flexible decision-making (5) and flexible behaviour (6) are consistent with Ng (1995). The concession that the “no-need-for-sentience” proposition is unnecessary also strengthens the importance of the target article’s conclusions.
Fine-Tuning The Criteria For Inferring Sentience, Culum Brown
Fine-Tuning The Criteria For Inferring Sentience, Culum Brown
Animal Sentience
“Sentience” means the capacity to feel, and feelings are private affairs. Sentience is hence extremely difficult to quantify in nonhuman animals. We have no direct means of determining whether an animal is sentient. Thus we rely on a series of indirect measures or criteria which collectively provide some level of confidence about the probability that an animal is sentient. Crump et al. propose a modified framework based on 8 criteria for estimating the likelihood of sentience in a target taxon. Whereas I very much like their proposed framework, I would suggest a couple of amendments that may improve it further: …
Generalizing Frameworks For Sentience Beyond Natural Species, Michael Levin
Generalizing Frameworks For Sentience Beyond Natural Species, Michael Levin
Animal Sentience
Crump et al. (2022) offer a well-argued example of an essential development: a rigorous framework for assessing sentience from the perspective of moral concern over an agent’s welfare. Current and forthcoming developments in bioengineering, synthetic morphology, artificial intelligence, biorobotics, and exobiology necessitate an expansion and generalization of this effort. Verbal reports (the Turing Test) and homology to human brains are utterly inadequate criteria for assessing the status of novel, unconventional agents that offer no familiar touchstone of phylogeny or anatomy. We must develop principled approaches to evaluating the sentience of (and thus, our responsibility to) beings of unfamiliar provenance and …
Sentience In Decapods: An Open Question, Mark Briffa
Sentience In Decapods: An Open Question, Mark Briffa
Animal Sentience
Crump et al.’s framework is a powerful tool designed to assist decisions on the ethical treatment of decapod crustaceans. However, the question of whether decapods are sentient (i.e., whether they feel), remains open, perhaps indefinitely. More optimistically, we might design experiments that distinguish among different levels of awareness, sometimes viewed as components of sentience. We should strike a balance between assuming that all organisms are sentient and making unnecessary anatomical assumptions about sentience. Refining current experiments may provide concrete insights about awareness in Decapoda and other taxa.
Does The Sentience Framework Imply All Animals Are Sentient?, Kristin Andrews
Does The Sentience Framework Imply All Animals Are Sentient?, Kristin Andrews
Animal Sentience
The eight criteria proposed in Crump et al.’s framework for evaluating pain sentience in decapod crustaceans are just the tip of the iceberg when it comes to markers that could increase confidence in an animal’s sentience more generally. Some of the commentaries have already pointed out that pain is only one kind of sentience (Souza Valente). It has also already been pointed out that there are other criteria for pain that could be usefully added to the framework’s eight (Burrell). This expansive thinking about criteria that can be used to increase confidence in sentience raisess the question: in an expansive …
Distinguishing Epistemic And Moral Grounds For Legal Protection, Carlos Montemayor
Distinguishing Epistemic And Moral Grounds For Legal Protection, Carlos Montemayor
Animal Sentience
The criteria proposed by Crump et al. are based on various cognitive roles associated with sentience. A subset of them may be sufficient for certain kinds of welfare, but the presence of all of them should be considered as clearly sufficient for substantial kinds of legal protection based on their relation to capacities that we consider essential for moral standing in human beings.
Unconscious Humans, Autonomous Machines And The Difficulty Of Knowing Which Animals Are Sentient, Marian Stamp Dawkins
Unconscious Humans, Autonomous Machines And The Difficulty Of Knowing Which Animals Are Sentient, Marian Stamp Dawkins
Animal Sentience
The framework proposed by Crump et al. still leaves much doubt about whether invertebrates such as crabs are sentient. For example, many complex behaviours - even in humans - occur without sentience. Also, simple machines could easily meet all of Crump et al.’s eight proposed criteria for sentience. Acknowledging the limitations of what we currently know about sentience is important both for formulating legislation correctly and for advancing scientific understanding of this most puzzling of biological phenomena.
Decapod Sentience: Broadening The Framework, Cecilia De Souza Valente
Decapod Sentience: Broadening The Framework, Cecilia De Souza Valente
Animal Sentience
A framework for studying sentience in decapods is of great value, but how high a cost (in suffering) to each individual decapod (or any animal) is warranted for collecting scientific evidence of sentience? The lack of evidence for some of the target article’s proposed criteria surely results from the fact that research is focused mainly on biomedical studies, ecotoxicology, and commercial production, with decapod sentience and welfare seen as only a secondary research topic. I draw attention also to the possibility of a wider framework that includes all felt experiences, from suffering to pleasure.
Independence, Weight And Priority Of Evidence For Sentience, Elizabeth Irvine
Independence, Weight And Priority Of Evidence For Sentience, Elizabeth Irvine
Animal Sentience
This commentary maps out relationships of dependency between the criteria proposed in the target article (Crump et al. 2022), identifying the criteria that carry most of the weight of the evidence, and suggesting which criteria should have priority in research on sentience.
Sentience In Decapods: Difficulties To Surmount, Michael L. Woodruff
Sentience In Decapods: Difficulties To Surmount, Michael L. Woodruff
Animal Sentience
In the target article Crump et al. present 8 criteria to assess whether decapods experience pain. Four of these -- sensory integration, motivational trade-offs, flexible self-protection, and associative learning -- could be used to assess sentience in general. In this commentary I discuss difficulties with using these criteria to provide evidence of sentience in decapods, particularly if this evidence is to change public opinion and policies. These difficulties are lack of evidence, the potential to eventually explain the neurobiological basis of the behaviors chosen as criteria, thereby eliminating any explanatory work for sentience, and the reluctance to bring animals that …
Decapod Sentience: Promising Framework And Evidence, Jon Mallatt, Todd E. Feinberg Md
Decapod Sentience: Promising Framework And Evidence, Jon Mallatt, Todd E. Feinberg Md
Animal Sentience
Strong points of the target article by Crump et al. are that it offers clear criteria for judging whether decapods are sentient, an effective semi-quantitative grading system for this purpose, and an astute, critical review of the literature. It concludes plausibly that major subgroups of decapods are sentient. A minor problem is that it includes classical, Pavlovian learning as a marker of sentience along with the more valid marker of complex (e.g., operant) learning. Another minor problem is that it does not distinguish results that are negative because of likely absence of sentience from results that are negative because they …
A Framework For Evaluating Evidence Of Pain In Animals, Matilda Gibbons, Lars Chittka
A Framework For Evaluating Evidence Of Pain In Animals, Matilda Gibbons, Lars Chittka
Animal Sentience
Crump et al. define eight criteria indicating sentience in animals, with a focus on pain. Here, we point out the risk of false negative or false positive diagnoses of pain. Criteria of different levels of inclusivity are useful for using the precautionary principle in animal welfare considerations, and for more formal scientific evidence of pain. We suggest tightening the criteria -- from more general evidence of sentience to pain alone -- because crucial evidence for animal welfare decisions might otherwise be missed for animals subjected to invasive and injurious procedures.
Animal Sentience Research: Synthesis And Proposals, Andrew Crump, Heather Browning, Alex Schnell, Charlotte Burn, Jonathan Birch
Animal Sentience Research: Synthesis And Proposals, Andrew Crump, Heather Browning, Alex Schnell, Charlotte Burn, Jonathan Birch
Animal Sentience
Most commentaries on our target article broadly support our approach to evaluating evidence of animal sentience. In this Response, we clarify the framework’s purpose and address criticisms of our criteria. A recurring theme is that a framework to synthesise current evidence of sentience is not the same as an agenda for future directions in animal sentience research. Although future directions are valuable, our framework aims to evaluate existing evidence and inform animal welfare legislation.
A Horor Theory For Introspective Consciousness, Adriana Renero, Richard Brown
A Horor Theory For Introspective Consciousness, Adriana Renero, Richard Brown
Publications and Research
Higher-order theories of consciousness typically account for introspection in terms of one’s higher-order thoughts being conscious, which would require a third-order thought—i.e., a thought about a thought about a mental state. In this work, we offer an alternative account of introspection that builds on the recent Higher-Order Representation of a Representation (HOROR) theory of phenomenal consciousness. According to HOROR theory, phenomenal consciousness consists in having the right kind of higher-order representation. We claim that this theory can be extended to introspection by recognizing that there is a distinctive kind of consciousness—i.e., introspective consciousness—which can be accounted for as the theory …
Lack Of Imagination Can Bias Our View Of Animal Sentience, Brian Key, Deborah Brown
Lack Of Imagination Can Bias Our View Of Animal Sentience, Brian Key, Deborah Brown
Animal Sentience
How an animal reacts to a sensory stimulus is often used to assess whether that animal can experience feelings such as pain and pleasure. This behavioural path is typically complemented with reference to how a human would normally respond to and experience an analogous stimulus. Together, these approaches can lead to a “hard to imagine otherwise” argument for feelings. It is time to go beyond these qualitative assessments and to now determine whether a nervous system can execute the neural functions necessary for sentience.
Legal Recognition Of Animal Sentience: The Case For Cautious Optimism, Jane Kotzmann
Legal Recognition Of Animal Sentience: The Case For Cautious Optimism, Jane Kotzmann
Animal Sentience
Rowan et al.’s target article provides a valuable indication of the work that was required to reach the point where animals are recognised as sentient in various laws. To ensure this work was not in vain, the language of sentience needs to be used as a moral currency to demand further cultural change involving greater human respect for animals.
All Living Organisms Are Sentient, Arthur S. Reber, Frantisek Baluska, William B. Miller Jr.
All Living Organisms Are Sentient, Arthur S. Reber, Frantisek Baluska, William B. Miller Jr.
Animal Sentience
We argue that all living organisms, from the simplest unicellular prokaryotes to Homo sapiens, have valenced experiences—feelings as states of preference—and are capable of cognitive representations. Bacteria can learn, form stable memories, and communicate, hence solve problems. Rowan et al.'s statement that "Subjective feelings are just that — subjective — and are available only to the animal (or human) experiencing them" is true but irrelevant. When we see a fish flopping about in the bottom of a boat we immediately recognize suffering without having a glimpse of the nature of piscine distress. Some controlled anthropomorphism can go a …
The Science Of Animal Sentience And The Politics Of Animal Welfare Should Be Kept Separate, Marian Stamp Dawkins
The Science Of Animal Sentience And The Politics Of Animal Welfare Should Be Kept Separate, Marian Stamp Dawkins
Animal Sentience
Although linked historically by Rowan et al., the scientific study of animal sentience and political campaigns to improve animal welfare should be kept separate, for at least two reasons. First, the separation makes it clear that standards of evidence acceptable for ethical or political decisions on animal welfare can be lower than those required for a rigorously scientific approach to animal sentience. Second, it helps to avoid confirmatory bias in the form of giving undue weight to results that are in line with pre-conceived ideas and political views.
The Reality And Prevalence Of Animal Sentience, Antonio Damasio
The Reality And Prevalence Of Animal Sentience, Antonio Damasio
Animal Sentience
Rowan et al use findings from neurobiology, clinical neurology, and general biology to argue for the extensive presence of sentience in animals, but they are wisely cautious concerning when in the phylogenetic scale that emergence occurred.
Desire, Culture, And The Body, Zoey Lavallee
Desire, Culture, And The Body, Zoey Lavallee
Dissertations, Theses, and Capstone Projects
What is the nature of desire? In this dissertation I develop a theory of desire according to which desires are essentially enculturated states that play the role of presenting favorable outcomes that act as inputs to intention formation, and thereby intentional action. This analysis of desire debunks a common assumption shared by prominent accounts of desire in philosophy of mind, what can be called the dualist assumption: that bodily desires such as urges and appetites differ in kind from conceptual desires that are typically described as higher cognitive attitudes. I argue that the desires traditionally understood as bodily or appetitive …
Positron Emission Tomography From 1930 To 1990: The Epistemology And Process Of Scientific Instrumentation, Rick Shang
Positron Emission Tomography From 1930 To 1990: The Epistemology And Process Of Scientific Instrumentation, Rick Shang
Arts & Sciences Graduate Student Theses and Dissertations
Positron Emission Tomography (PET) is a groundbreaking detection system that, among many other applications, enabled neuroscience researchers to detect and image physiological changes in the brain associated with cognitive operations as subjects perform a task. This technology helped researchers learn to explore the physiological basis of human cognition in new ways and was the immediate forerunner of functional Magnetic Resonance Imaging (fMRI), a technology that continues to dominate the neurosciences. PET was also the founding invention of a new field of cognitive science: human functional neuroimaging. Indeed, some would say that PET encouraged a particular way of understanding the brain …
The Disunity Of Perception, Benjamin Austin Henke
The Disunity Of Perception, Benjamin Austin Henke
Arts & Sciences Graduate Student Theses and Dissertations
This dissertation argues for disunity in perceptual processing: rather than outputting to a single ‘centralized’ cognitive system, separate perceptual processing pathways produce different person-level representations for different purposes. I argue that this disunity has important implications for abstract theorizing in the philosophy and cognitive science of perception, for experimental methodology, and for our understanding of the normative role of perception itself. The first three chapters explore models in cognitive neuroscience which support perceptual disunity. In Chapter 1, I argue that a version of Milner and Goodale’s (2006) influential ‘two visual streams hypothesis’ survives its recent empirical challenges. In Chapter 2, …

Medical Schools Ignore The Nature Of Consciousness At Great Cost, Anoop Kumar
Medical Schools Ignore The Nature Of Consciousness At Great Cost, Anoop Kumar
Journal of Wellness
The essential question of the relationship between consciousness and matter is ignored in medical school curricula, leading to a machine-like view of the human being that contributes to physician burnout and intellectual dissatisfaction. The evidence suggesting that the brain may not be the seat of consciousness is generally ignored to preserve the worldview of the primacy of matter. By investigating new frameworks detailing the nature of consciousness at different levels of hierarchy, we can bring intellectual rigor to a once opaque subject that supports a fundamental reality about our experience: We are human beings, not only human bodies.
