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 …

How Not To Move The Line Drawn On Pain, Bjorn H. Merker

Animal Sentience

In this second commentary I outline the inadequacy of Key's responses to the many peer critiques of his thesis that have so far appeared in Animal Sentience. I illustrate with examples drawn from his response to my first commentary.

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?

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 …

Animal Welfare And Animal Rights, M.E. Rolle

Animal Sentience

This overview of Broom’s book, Sentience and Animal Welfare (2014), considers the role the book could play in the animal rights debate. In a thoroughly researched and objectively presented text, Broom lays out information that could place doubt in the minds of decision-makers. By highlighting not just the ways animals resemble humans, but also the ways humans resemble animals, Broom shines a light on a solidly grey area in the animal rights debate.

The Effects Of Construal Level On Stigmatizing Attitudes Toward An Individual With Mental Illness, Jeremy Glenn Gay

College of Graduate Studies: Theses & Dissertations

People with mental illness often face stigmatization by society. However, little research has examined cognitive factors that may activate or dissipate stigmatizing attitudes toward those with mental illness. Construal level, or the extent that people focus on abstract generalizations versus concrete details of events, may be one such cognitive factor. Two contradictory hypotheses emerged concerning how construal may affect stigmatizing attitudes. One hypothesis suggests that abstract construals will decrease stigmatization because abstract construals tend to increase the activation of similar goals, thus leading to a similarity focus. In contrast, another hypothesis suggests that abstract construals will increase stigmatization because abstract …

Animal Mourning: Précis Of How Animals Grieve (King 2013), Barbara J. King

Animal Sentience

Abstract: When an animal dies, that individual’s mate, relatives, or friends may express grief. Changes in the survivor’s patterns of social behavior, eating, sleeping, and/or of expression of affect are the key criteria for defining grief. Based on this understanding of grief, it is not only big-brained mammals like elephants, apes, and cetaceans who can be said to mourn, but also a wide variety of other animals, including domestic companions like cats, dogs, and rabbits; horses and farm animals; and some birds. With keen attention placed on seeking where grief is found to occur and where it is absent …

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.

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 …

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.

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.

Do Placement And Repetition Of Information In Pictorials Affect Comprehension And Memory Of Medication Instructions?, Jessica Le

College of Graduate Studies: Theses & Dissertations

The purpose of this study was to examine how text and picture pairings affected comprehension and memory for medication instructions. Participants viewed instructions on how to prepare a mock oral suspension drug. These instructions either had the picture repeat the information in the text, or complement information in the text. The text instructions were also either integrated into the pictures, or were separated from the pictures. Next, participants were assessed on their comprehension and memory including memory for the order of the steps and their belief in their ability to carry out this task effectively. The results indicated that participants …

Perceptions In Predicting Actor And Partner Sexual And Relational Satisfaction In Couple Relationships, Lucia Novakova

Theses and Dissertations--Family Sciences

The present exploration of perceptual accuracy and bias in romantic relationships bridges a gap in the literature on the ability of partners to estimate one another’s level of relational and sexual satisfaction, and its impact on their own and their partner’s level of satisfaction. A sample of 50 couples, recruited internationally, in continuously monogamous relationships of at least six-months in length completed online assessments of their relationship. The degree of accuracy and bias of their perception was established by comparing actor’s estimates of their partner’s satisfaction with the partner’s actual, self-reported satisfaction scores. The actor-partner interdependence model (APIM; Kenny, Kashy, …

Title: Parents And Teachers’ Perceptions And Clinical Diagnosis Of Autism Among White And Non-White Groups, Margaret Gopaul

Walden Dissertations and Doctoral Studies

The pervasiveness of autism has significantly increased over the past 2 decades with the 2014 Center for Disease Control and Prevention report indicating 1 in 68 children are diagnosed with Autism Spectrum Disorder (ASD). Early intervention is recommended as the most effective treatment approach. Nevertheless, previous research has indicated that White children are diagnosed with ASD about 1.5 years earlier than are Non-White children. A current gap remains in literature regarding ASD and different racial groups, and evidence has been inconclusive regarding disparities in identifying and diagnosing ASD. To fill this gap, this study investigated the relationship between child race, …

Getting Active With Passive Crossings: Investigating The Efficacy Of In-Vehicle Auditory Alerts For Rail Road Crossings, Steven Landry

Dissertations, Master's Theses and Master's Reports

Train-vehicle collisions at highway-rail grade crossings continue to be a major issue in the US and across the world. Installing additional hardware at individual crossings is expensive, time consuming, and potentially ineffective. To prevent recent trends in safety improvement from plateauing, experts are turning towards novel warning devices that can be applied to all crossings with minimal cost. In-vehicle auditory alerts (IVAAs) could potentially remedy many of the human factor issues related to crossing safety in a cost effective manner.

This thesis presents a series of experiments designing and testing an IVAA system for grade level railroad (RR) crossings. Study …

An Analysis Of Stakeholders Communication In Collaborative Software Development Projects, Wei Zhang

Dissertations, Master's Theses and Master's Reports

Software development is a multidisciplinary collaboration involving many stakeholders. However, existing software development processes exhibit many issues related to that collaboration. Because prior research on stakeholder analysis and teamwork revealed the importance of communication, this study analyzed stakeholder communication with reference to team activities as a social and cognitive process. The study’s goal was to understand the collaboration process during software development and to delineate factors that influence this process. We focused on communication between the software developers and their clients during the requirements gathering phase, the team process, and the inter-team and interdisciplinary collaboration, in particular between software engineers …

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.

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.

Confidence Judgments In A Simultaneous Task Using Sprague Dawley Rats (Rattus Norvegicus), Jessica K. Kumm

Graduate Student Theses, Dissertations, & Professional Papers

In the present experiment, metacognitive confidence judgments were measured in the Sprague-dawley rats using a simultaneous discrimination task. Performance on two types of trials were compared: Forced and Choice. For Forced trials, subjects were required to classify a range of eight tones as either a “long” or “short” tone with the four longest frequency durations comprising the “long” tone category and the four shortest frequency tones comprising the “short” tone duration category. The Choice trials were identical to the Forced trials with the exception that a bailout response was also available, allowing the subject to advance to the next trial …

The Relationship Between Nursing Students' Perceptions Of Staff Nurses' Attitudes Towards Them And Self-Efficacy In Sophomore- And Senior- Level Nursing Students, Sarah A. Mueller, Raechel M. Naragon, Rachael R. Smith

Williams Honors College, Honors Research Projects

Clinical teaching gives nursing students practical experience, allowing them to practice skills and to apply theories of nursing alongside a staff nurse. The purpose of this study was to examine the relationship between nursing students’ perceptions of staff nurses’ attitudes towards them and self-efficacy in sophomore- and senior-level nursing students. According to scientist Albert Bandura’s Social Cognitive Theory, self-efficacy is defined as a person’s belief in his or her own abilities. Using non-experimental comparative design, convenience sampling, and Likert scale questionnaires, sophomore- and senior- level baccalaureate nursing students were asked to complete the survey using the Nursing Clinical Self-Efficacy …

Slam Poetry: An Online Intervention For Treating Depression, Spencer J. Ruchti, Mercedes Becker, Cara Mckee, Austin Herron, Alex Swalling

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Given that depression is the “leading cause of disability worldwide,” and that less than 50% of people suffering from depression receive treatment, this study aims to provide support for a globally accessible depression treatment (WHO, 2012). The study conducted implemented an internet-based treatment for depression in which users were provided an opportunity to watch slam poetry videos related to mental health issues and write free responses regarding the content of the videos and their subjective experience of depression. Numerous studies provide support for the effectiveness of expressive writing, online mental health interventions, and slam poetry in particular for reducing symptoms …

Chronic Pain Causal Attributions In An Interdisciplinary Primary Care Clinic: Patient-Provider And Provider-Provider Discrepancies, Bryan Jensen

Theses and Dissertations

The purpose of the present study was to investigate the influence of pain causal attributions on patient pain-related functioning, treatment engagement, and clinical outcomes. Additionally, the impact of discordant pain causal attributions between patients and their providers as well as between interdisciplinary providers was examined. Patients rated their pain functioning and causal pain attributions during a regular clinic visit. Following the patient’s visit both the behavioral medicine provider and internal medicine resident provided ratings of similar pain-related functioning domains and causal attributions. Follow-up data were collected from the electronic medical record three months following that clinic visit. Overall, results revealed …

The Effect Of Inversion And Motor Expertise On Body Compatibility, Harrison M. Goodall Iii

Pomona Senior Theses

Previous studies have established that when a subject’s attention is directed to a specific body part, the subject is able to move that body part faster than a body part their attention was not drawn to. This is known as the body compatibility effect, and it has been shown that this effect only occurs when viewing upright images of the human body. In this study, we presented control subjects and expert acrobats with inverted and upright stimuli. We hypothesized that the amount of time the acrobats spent inverted would result in the acrobats exhibiting body compatibility effects for both upright …

Reflections Of The Social Environment In Chimpanzee Memory: Applying Rational Analysis Beyond Humans, Jeffrey R. Stevens, Julian N. Marewski, Lael J. Schooler, Ian C. Gilby

Jeffrey Stevens Publications

In cognitive science, the rational analysis framework allows modelling of how physical and social environments impose information-processing demands onto cognitive systems. In humans, for example, past social contact among individuals predicts their future contact with linear and power functions. These features of the human environment constrain the optimal way to remember information and probably shape how memory records are retained and retrieved. We offer a primer on how biologists can apply rational analysis to study animal behaviour. Using chimpanzees (Pan troglodytes) as a case study, we modelled 19 years of observational data on their social contact patterns. Much …

Cognitive Phenotypes And The Evolution Of Animal Decisions, Tamra C. Mendelson, Courtney L. Fitzpatrick, Mark E. Hauber, Charles H. Pence, Rafael L. Rodriguez, Rebecca J. Safran, Caitlin A. Stern, Jeffrey R. Stevens

Jeffrey Stevens Publications

Despite the clear fitness consequences of animal decisions, the science of animal decision making in evolutionary biology is underdeveloped compared with decision science in human psychology. Specifically, the field lacks a conceptual framework that defines and describes the relevant components of a decision, leading to imprecise language and concepts. The ‘judgment and decision-making’ (JDM) framework in human psychology is a powerful tool for framing and understanding human decisions, and we apply it here to components of animal decisions, which we refer to as ‘cognitive phenotypes’. We distinguish multiple cognitive phenotypes in the context of a JDM framework and highlight empirical …

Context-Dependent Seed Dispersal By A Scatter-Hoarding Corvid, Mario B. Pesendorfer, T. Scott Sillett, Scott A. Morrison, Alan C. Kamil

Avian Cognition Papers

1. Corvids (crows, jays, magpies and nutcrackers) are important dispersers of large-seeded plants. Studies on captive or supplemented birds suggest that they flexibly adjust their scatter-hoarding behavior to the context of social dynamics and relative seed availability. Because many corvid-dispersed trees show high annual variation in seed production, context-dependent foraging can have strong effects on natural corvid scatter-hoarding behavior.

2. We investigated how seed availability and social dynamics affected scatter-hoarding in the island scrub jays (Aphelocoma insularis). We quantified rates of scatter-hoarding behavior and territorial defense of 26 colormarked birds over a three-year period with variable acorn crops. …

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.

Cognitive Complexity, Mindfulness, And Reflection In Mental Health Professionals, Dharshini Goonetilleke

All Graduate Theses, Dissertations, and Other Capstone Projects

In this cross sectional quantitative investigation, the relationships among mental health professionals' cognitive complexity, mindfulness, and reflection were explored. To determine if there was a correlation between mindfulness and cognitive complexity, a Pearson's correlation was conducted: There was a strong positive correlation between mindfulness and cognitive complexity. To determine whether observing and describing (two key variables of mindfulness) could predict counselor overall cognitive complexity, a simultaneous multiple regression was conducted. The observing subscale significantly predicted counselor cognitive complexity and the describing subscale did not significantly predict mindfulness. To determine if there is a correlation between mindfulness and reflection, a Pearson's …

Why Fish Do Not Feel Pain, Brian Key

Animal Sentience

Only humans can report feeling pain. In contrast, pain in animals is typically inferred on the basis of nonverbal behaviour. Unfortunately, these behavioural data can be problematic when the reliability and validity of the behavioural tests are questionable. The thesis proposed here is based on the bioengineering principle that structure determines function. Basic functional homologies can be mapped to structural homologies across a broad spectrum of vertebrate species. For example, olfaction depends on olfactory glomeruli in the olfactory bulbs of the forebrain, visual orientation responses depend on the laminated optic tectum in the midbrain, and locomotion depends on pattern generators …

An Invertebrate Perspective On Pain, Jennifer A. Mather

Animal Sentience

Although Key (2016) argues that mammals feel pain and fish do not, from an invertebrate perspective, it is obvious that the pain experience is shared by animals from a number of different animal groups.
