Why Babies Do Not Feel Pain, Or: How Structure-Derived Functional Interpretations Can Go Wrong, Helmut Segner Jan 2016

Why Babies Do Not Feel Pain, Or: How Structure-Derived Functional Interpretations Can Go Wrong, Helmut Segner

Animal Sentience

The response to pain involves a non-conscious, reflexive action and a conscious perception. According to Key (2016), consciousness — and thus pain perception — depends on a neuronal correlate that has a “unique neural architecture” as realized in the human cortex. On the basis of the “bioengineering principle that structure determines function,” Key (2016) concludes that animal species such as fish, which lack the requisite cortex-like neuroanatomical structure, are unable to feel pain. This commentary argues that the relationship between brain structure and brain function is less straightforward than suggested in Key’s target article.

A Review On Locomotor Training After Spinal Cord Injury: Reorganization Of Spinal Neuronal Circuits And Recovery Of Motor Function, Andrew C. Smith, Maria Knikou Jan 2016

A Review On Locomotor Training After Spinal Cord Injury: Reorganization Of Spinal Neuronal Circuits And Recovery Of Motor Function, Andrew C. Smith, Maria Knikou

Publications and Research

Locomotor training is a classic rehabilitation approach utilized with the aim of improving sensorimotor function and walking ability in people with spinal cord injury (SCI). Recent studies have provided strong evidence that locomotor training of persons with clinically complete, motor complete, or motor incomplete SCI induces functional reorganization of spinal neuronal networks at multisegmental levels at rest and during assisted stepping. This neuronal reorganization coincides with improvements in motor function and decreased muscle cocontractions. In this review, we will discuss the manner in which spinal neuronal circuits are impaired and the evidence surrounding plasticity of neuronal activity after locomotor training …

Are Coloring Books Really Just For Kids? Investigating Possible Effects Of Specific Pattern Coloring On Conceptual, Physiological And Behavioral Aspects Of Anxiety, Hannah Taylor Jan 2016

Are Coloring Books Really Just For Kids? Investigating Possible Effects Of Specific Pattern Coloring On Conceptual, Physiological And Behavioral Aspects Of Anxiety, Hannah Taylor

Scripps Senior Theses

This study examined the role of specific pattern coloring, such as coloring books for adults, on conceptual, behavioral and physiological measures of anxiety. Undergraduate female students (n = 8) had ECG electrodes and a respiration belt attached and completed the State Trait Anxiety Inventory (STAI) at five time points; at baseline, after an initial autobiographical anxiety induction, following a passive relaxation condition, after a repeat induction and then after a coloring condition. The participants were randomly split into a control and experimental group; the control group free colored while the experimental group colored in a mandala pattern. Participants had the …

Evaluating Competition Between Verbal And Implicit Systems With Functional Near-Infrared Spectroscopy, Troy A. Schiebel Jan 2016

Evaluating Competition Between Verbal And Implicit Systems With Functional Near-Infrared Spectroscopy, Troy A. Schiebel

Honors Undergraduate Theses

In category learning, explicit processes function through the prefrontal cortex (PFC) and implicit processes function through the basal ganglia. Research suggested that these two systems compete with each other. The goal of this study was to shed light on this theory. 15 undergraduate subjects took part in an event-related experiment that required them to categorize computer-generated line-stimuli, which varied in length and/or angle depending on condition. Subjects participated in an explicit "rule-based" (RB) condition and an implicit "information-integration" (II) condition while connected to a functional near-infrared spectroscopy (fNIRS) apparatus, which measured the hemodynamic response (HR) in their PFC. Each condition …

The Object Of Grief, Clark Glymour Jan 2016

The Object Of Grief, Clark Glymour

Animal Sentience

King’s new book is a wonderful collection of diverse anecdotes illustrating the variety of animal practices that are convincing illustrations of grief. Those who want scientific arguments for that conclusion should, however, read elsewhere.

Animal Suffering Calls For More Than A Bigger Cage, Simon R. B. Leadbeater Jan 2016

Animal Suffering Calls For More Than A Bigger Cage, Simon R. B. Leadbeater

Animal Sentience

Ng (2016) argues for incremental welfare biology partly because it would be impossible to demonstrate conclusively that animals are sentient. He argues that low cost changes in industrial practices and working collaboratively may be more effective in advancing animal welfare than more adversarial approaches. There is merit in some of Ng’s recommendations but a number of his arguments are, in my view, misdirected. The fact that nonhuman animals feel has already been adequately demonstrated. Cruelty to animals is intrinsic to some industries, so the only way to oppose it is to oppose the industry.

Does The Pain Of Rejection Promote The Pleasure Of Revenge? A Neural Investigation Of Cingulo-Striatal Contributions To Violence, David Chester Jan 2016

Does The Pain Of Rejection Promote The Pleasure Of Revenge? A Neural Investigation Of Cingulo-Striatal Contributions To Violence, David Chester

Theses and Dissertations--Psychology

Aggression is a dynamic and costly feature of human behavior. One reliable cause of aggression is social rejection, though the underlying mechanisms of this effect remain to be fully understood. Previous research has identified two psychological processes that are independently linked to aggressive retaliation: pain and pleasure. Given recent findings that pain magnifies the experience of pleasure, I predicted that the pain of rejection would promote the pleasure of aggression and thus, aggression itself. I also expected that this indirect effect of aggressive pleasure would only be observed among individuals with weaker self-regulatory abilities that are necessary to cope with …

Modulation Of Behavior In Communicating Emotion, Martin Gardiner Jan 2016

Modulation Of Behavior In Communicating Emotion, Martin Gardiner

Animal Sentience

King discusses many examples where two animals, as they bond, behave in ways we interpret as expressing love for one another. If one of the bonded animals then dies, signs of loving are replaced by signs we interpret as expressing grief by the animal who remains. I propose a pathway for emotional communication between an animal and an observer that can have a central role in these and other observations by King and in our overall ability to interpret observed behavior in relation to emotion. This pathway provides evidence of emotion in an observed animal by communicating evidence of emotion’s …

Sentience And Animal Welfare: Affirming The Science And Addressing The Skepticism, Nancy Clarke Jan 2016

Sentience And Animal Welfare: Affirming The Science And Addressing The Skepticism, Nancy Clarke

Animal Sentience

Broom’s (2014) book is a well-researched and thoroughly written exploration and evaluation of the journey from the origins of animal welfare science to what we can say we now know and need to consider in relation to animal sentience and welfare. This book will help to counter any skepticism among academics and policy makers.

Nonhuman Mind-Reading Ability, Marthe Kiley-Worthington Jan 2016

Nonhuman Mind-Reading Ability, Marthe Kiley-Worthington

Animal Sentience

Harnad (2016) is mistaken that humans are better at mind-reading than other species. Humans have context-independent language, but nonhuman species, especially mammals, have context-dependent nonverbal skills – perceptual, communicative and social -- that can be much keener than our own.

Cognitive Evidence Of Fish Sentience, Jonathan Balcombe Jan 2016

Cognitive Evidence Of Fish Sentience, Jonathan Balcombe

Animal Sentience

I present a little-known example of flexible, opportunistic behavior by a species of fish to undermine Key’s (2016) thesis that fish are unconscious and unable to feel. Lack of a cortex is flimsy grounds for denying pain to fish, for on that criterion we must also then deny it to all non-mammals, including birds, which goes against scientific consensus. Notwithstanding science’s fundamental inability to prove anything, the precautionary principal dictates that we should give the benefit of the doubt to fish, and the state of the oceans dictates that we act on it now.

Mediating Claims Through Critical Anthropomorphism, Gordon Burghardt Jan 2016

Mediating Claims Through Critical Anthropomorphism, Gordon Burghardt

Animal Sentience

Key’s (2016) discussion of his claim that fish do not feel pain ignores the history of attempts to study the attribution of mental states to other species. Although willing to accept that mammals feel pain, Key claims that fish lack the mammalian neural mechanisms underlying pain and are unconscious of their experiences. Consequently, we do not need to be overly concerned about fishing practices that would otherwise be viewed as painful. Key uses a flawed anthropomorphic lens. All attributions of mental events to organisms other than oneself involve inferences derived from anthropomorphic processes through which we process physiological and behavioral …

Fish Lack The Brains And The Psychology For Pain, Stuart W.G. Derbyshire Jan 2016

Fish Lack The Brains And The Psychology For Pain, Stuart W.G. Derbyshire

Animal Sentience

Debate about the possibility of fish pain focuses largely on the fish’s lack of the cortex considered necessary for generating pain. That view is appealing because it avoids relatively abstract debate about the nature of pain experience and subjectivity. Unfortunately, however, that debate cannot be entirely avoided. Subcortical circuits in the fish might support an immediate, raw, “pain” experience. The necessity of the cortex only becomes obvious when considering pain as an explicitly felt subjective experience. Attributing pain to fish only seems absurd when pain is considered as a state of explicit knowing.

Pain And Other Feelings In Humans And Animals, Antonio Damasio, Hanna Damasio Jan 2016

Pain And Other Feelings In Humans And Animals, Antonio Damasio, Hanna Damasio

Animal Sentience

Evidence from neuroanatomy, neurophysiology, and neuropsychology suggests that the experience of feelings in humans does not depend exclusively on structures of the cerebral cortex. It does not seem warranted to deny the possibility of feeling in animals on the grounds that their cerebral cortices are not comparable to those of humans.

Consumer Neuroscience: A Multi-Disciplinary Approach To Marketing Leveraging Advances In Neuroscience, Psychology And Economics, Bridget E. Blum Jan 2016

Consumer Neuroscience: A Multi-Disciplinary Approach To Marketing Leveraging Advances In Neuroscience, Psychology And Economics, Bridget E. Blum

CMC Senior Theses

For decades, neuroscience has greatly contributed to our foundational understanding of human behavior. More recently, the findings and methods of neuroscience have been applied to study the process of decision-making in order to offer advanced insights into the neural mechanisms that influence economic and consumer choices. In this thesis, I will address how customized marketing strategies can be enriched through the integration of consumer neuroscience, an integrative field anchored in the biological, cognitive and affective mechanisms of consumer behavior. By recognizing and utilizing these multidisciplinary interdependencies, marketers can enhance their advertising and promotional mix to elicit desired neural and affective …

Vitamin D Clinical Relevance In The Recovery From Traumatic Brain Injury Among The Military Population, Yuisa M. Colón Jan 2016

Vitamin D Clinical Relevance In The Recovery From Traumatic Brain Injury Among The Military Population, Yuisa M. Colón

Honors Undergraduate Theses

Background: Traumatic brain injury (TBI) still remains a difficult disorder to treat. TBI has been associated to chronic neuroinflammation and a high risk for neurodegenerative disorders. Since 2001 between ten to twenty percent of all deployed military members have suffered a combat-related TBI. Nearly twenty to thirty percent of those will experience chronic cognitive, behavioral and somatic symptoms after suffering a TBI.
Methods: The objective of this review is to evaluate current literature examining vitamin D as a neurosteroid with protective properties and its clinical relevance after traumatic brain injury. Vitamin D is known to participate in neurobiological …

Anthropomorphic Denial Of Fish Pain, Lynne U. Sneddon, Matthew C. Leach Jan 2016

Anthropomorphic Denial Of Fish Pain, Lynne U. Sneddon, Matthew C. Leach

Animal Sentience

Key (2016) affirms that we do not know how the fish brain processes pain but denies — because fish lack a human-like cortex — that fish can feel pain. He affirms that birds, like fish, have a singly-laminated cortex and that the structure of the bird brain is quite different from that of the human brain, yet he does not deny that birds can feel pain. In this commentary we describe how Key cites studies that substantiate mammalian pain but discounts the same kind of data as evidence of fish pain. We suggest that Key's interpretations are illogical, do not …

Potential For Aerobic Exercise To Release Growth Factors To Induce Cognitive Changes In Children With Autism Spectrum Disorder, Maya Harrington Jan 2016

Potential For Aerobic Exercise To Release Growth Factors To Induce Cognitive Changes In Children With Autism Spectrum Disorder, Maya Harrington

Undergraduate Research Posters

Autism Spectrum Disorder (ASD) is becoming increasingly prevalent among adolescents, and while the number of individuals diagnosed with the disorder grows, there continues to be no cure or even a clear treatment path for ASD. This study analyzes the biological stimulations that create cognitive changes—which are induced by intensive aerobic exercise—within the brains of individuals ages 8-18 diagnosed with autism. I studied journal articles on the current treatments available for ASD, the increasing prevalence of the disease, the cognitive alterations of the autistic brain relative to the brains of individuals without the disease, the release of growth factors due to …

Fish Pain: A Painful Topic, Carl Safina Jan 2016

Fish Pain: A Painful Topic, Carl Safina

Animal Sentience

If fish cannot feel pain, why do stingrays have purely defensive tail spines that deliver venom? Stingrays’ ancestral predators are fish. And why do many fishes possess defensive fin spines, some also with venom that produces pain in humans? These things did not evolve just in case sentient humans would evolve millions of years later and then invent scuba. If fish react purely unconsciously to “noxious” stimuli, why aren’t sharp jabbing spines enough? Why also stinging venom?

How Welfare Biology And Commonsense May Help To Reduce Animal Suffering, Yew-Kwang Ng Jan 2016

How Welfare Biology And Commonsense May Help To Reduce Animal Suffering, Yew-Kwang Ng

Animal Sentience

Welfare biology is the study of the welfare of living things. Welfare is net happiness (enjoyment minus suffering). Since this necessarily involves feelings, Dawkins (2014) has suggested that animal welfare science may face a paradox, because feelings are very difficult to study. The following paper provides an explanation for how welfare biology could help to reduce this paradox by answering some difficult questions regarding animal welfare. Simple means based on commonsense could reduce animal suffering enormously at low or even negative costs to humans. Ways to increase the influence of animal welfare advocates are also discussed, focusing initially on farmed …

Why Animal Welfarism Continues To Fail, Lori Marino Jan 2016

Why Animal Welfarism Continues To Fail, Lori Marino

Animal Sentience

Welfarism prioritizes human interests over the needs of nonhuman animals. Despite decades of welfare efforts other animals are mostly worse off than ever before, being subjected to increasingly invasive and harmful treatments, especially in the factory farming and biomedical research areas. A legal rights-based approach is essential in order for other animals to be protected from the varying ethical whims of our species.

Understanding Emotional Suffering, Barbara J. King Jan 2016

Understanding Emotional Suffering, Barbara J. King

Animal Sentience

In responding to insightful commentaries from 7 scholars, for which I am grateful, I offer new thoughts on whether animals can conceptualize and express signs of grief. I also discuss why I included both weak and strong examples of animal mourning, and how this work may help us think about enhanced welfare for animals, including freedom from emotional suffering.

On The Sentience Of Fish, Pentti O. Haikonen Jan 2016

On The Sentience Of Fish, Pentti O. Haikonen

Animal Sentience

Key’s (2016) target article, “Why fish do not feel pain,” is based on a moralistic fallacy where conclusions about natural conditions are drawn not from research and experiments, but from subjective moral views on how things should be. Moreover, the neurobiological findings purporting to show that fish do not feel pain are insufficient for drawing this conclusion.

Pain In Parallel, Peter Godfrey-Smith Jan 2016

Pain In Parallel, Peter Godfrey-Smith

Animal Sentience

Key's (2016) arguments against the view that fish feel pain can be shown to be fallacious by considering some damage-related behaviors in invertebrates. Pain may have different neural bases in different organisms, so the absence in fish of the cortical structures that might underlie pain in mammals does not settle the question of fish pain.

Cortex Necessary For Pain — But Not In Sense That Matters, Adam J. Shriver Jan 2016

Cortex Necessary For Pain — But Not In Sense That Matters, Adam J. Shriver

Animal Sentience

Certain cortical regions are necessary for pain in humans in the sense that, at particular times, they play a direct role in pain. However, it is not true that they are necessary in the more important sense that pain is never possible in humans without them. There are additional details from human lesion studies concerning functional plasticity that undermine Key’s (2016) interpretation. Moreover, no one has yet identified any specific behaviors that mammalian cortical pain regions make possible that are absent in fish.

Falsifying The Null Hypothesis That “Fish Do Not Feel Pain", Brian Key Jan 2016

Falsifying The Null Hypothesis That “Fish Do Not Feel Pain", Brian Key

Animal Sentience

The reader of Animal Sentience may surmise that because the weight of the commentaries on my target article, “Why fish do not feel pain,” is leaning towards not supporting my argument, it follows that the premise "fish do not feel pain" is incorrect. However, science does not prevail by popular opinion. History is plagued with numerous (and often widely accepted) examples of biological phenomena being explained by mysterious forces. In the absence of a mechanistic understanding, the many different guises of vitalism (the principle that life involves a vital energy) are often invoked to explain the unknown. Spurious …

The Effects Of External Focus Of Attention Exercise Rehabilitation On Dual Task Walking In Parkinson's Disease, Eric N. Beck Jan 2016

The Effects Of External Focus Of Attention Exercise Rehabilitation On Dual Task Walking In Parkinson's Disease, Eric N. Beck

Theses and Dissertations (Comprehensive)

Parkinson’s disease impairs control of well-learned movements, and therefore, individuals with Parkinson’s disease are forced to walk with greater conscious control. This causes difficulties while walking and completing a secondary task simultaneously (dual tasking), in that distractions from conscious control of walking increase the risk of falls and injury. Although, attention-based exercise may be a potential avenue to decrease the demands associated with walking in Parkinson’s disease. For example, an external focus of attention (on manipulated objects) has been found to recruit the networks that are important for walking with little conscious control (automatic control networks). In contrast, an internal …

Death In The Family, Maria Botero Jan 2016

Death In The Family, Maria Botero

Animal Sentience

Barbara King presents grief as the result of the capacity of human and non-human animals for social and affectionate bonds. This is a novel approach that provides a context for interpreting behavioral evidence of grief. The book also offers thought-provoking insights into the relationship between emotion and the expression of emotion. The most surprising element of King’s approach is that, throughout the book, her account of non-human animal grief forces us to reassess the way we treat them.

Considering Animals’ Feelings: Précis Of Sentience And Animal Welfare (Broom 2014), Donald M. Broom Jan 2016

Considering Animals’ Feelings: Précis Of Sentience And Animal Welfare (Broom 2014), Donald M. Broom

Animal Sentience

The concept of sentience concerns the capacity to have feelings. There is evidence for sophisticated cognitive concepts and for both positive and negative feelings in a wide range of nonhuman animals. All vertebrates, including fish, as well as some molluscs and decapod crustaceans have pain systems. Most people today consider that their moral obligations extend to many animal species. Moral decisions about abortion, euthanasia, and the various ways we protect animals should take into account the research findings about sentience. In addition, all animal life should be respected and studies of the welfare of even the simplest invertebrate animals should …

Is Sentience Only A Nonessential Component Of Animal Welfare?, Ian J.H. Duncan Jan 2016

Is Sentience Only A Nonessential Component Of Animal Welfare?, Ian J.H. Duncan

Animal Sentience

According to Broom (2014), animal welfare is a concept that can be applied to all animals, including single-celled organisms that are obviously not sentient. Such a stance makes it difficult to draw a connection between welfare and sentience, and that is the book’s downfall. Some excellent points are made about sentience and there are very good discussions on animal welfare. However, unless sentience is considered the essential component of welfare, any attempt to link the two phenomena will be unsuccessful — and that, indeed, is the case with this book.
