Its Skin Is My Skin, Bryan Page

Graduate School of Art Theses

This text examines the complexity of attempting to empathize with bodies that are vastly othered from my own. This broad yet nuanced subject crosses epistemological boundaries and complicates the dualities between both the mind and body, and between the corporeal and the virtual. My desire to better understand the conditions of another’s experience originates from a painful traumatic loss which caused me to feel isolated and incomplete. In response to this suffering, I long to emotionally connect with other beings and create artwork that attempts to bridge the qualia of individual experience.

I am interested in the capacity (or lack …

Observation Of Visitors At A Chimpanzee (Pan Troglodytes Schweinfurthii) Ecotourism Site Reveals Opportunity For Multiple Modes Of Pathogen Transmission, Darcey Glasser

Theses and Dissertations

Chimpanzee (Pan troglodytes) tracking is a popular ecotourism activity across Sub-Saharan Africa, offering visitors a personal wildlife experience. However, chimpanzee ecotourism may increase the risk of disease transmission between chimpanzees and people. This study assessed how tourist behaviors might facilitate cross-species disease transmission in Kibale National Park, Uganda.

A Study Of Beluga (Delphinapterus Leucas) Vocal Ontogeny, Audra Elizabeth Ames

Dissertations

There is a shortage of literature regarding beluga (Delphinapterus leucas) vocal ontogeny, as presently, there has only been one published study on the vocal development of beluga calves, despite the value of ontogenetic studies for our understanding of sound-centered species. Here I offer the second longitudinal study of beluga vocal development. Using a calibrated digital hydrophone with a sampling rate of 256 kHz, I studied the vocal progression of a male beluga calf in early life. From his first day, the calf produced broadband pulse trains with upper frequency limits extending past the study’s Nyquist frequency (128 kHz); …

First Thirty Days Of Life: Examining Calf Behavioral Development In Beluga Whales (Delphinapterus Leucas) And Pacific White-Sided Dolphins (Lagenorhyncus Obliquidens) At One Zoological Facility, Kendal Smith

Master's Theses

Cetacean development is important for general comparative understanding and the implementation of informed husbandry policies. Due to the inaccessibility of many of these species in the wild, researchers can study managed care populations to better understand basic developmental patterns of cetaceans, as well as to improve husbandry policies for facility animals. However, no previous studies have attempted to observe the behavioral development of Pacific white-sided dolphins (Lagenorhyncus obliquidens). Eight beluga whale calves and four Pacific white-sided dolphin calves were observed for the first 30 days of life to determine the developmental trajectory of several typically monitored behaviors. The …

Stabilizing Forces In Acoustic Cultural Evolution: Comparing Humans And Birds, Daniel C. Mann

Dissertations, Theses, and Capstone Projects

Learned acoustic communication systems, like birdsong and spoken human language, can be described from two seemingly contradictory perspectives. On one hand, learned acoustic communication systems can be remarkably consistent. Substantive and descriptive generalizations can be made which hold for a majority of populations within a species. On the other hand, learned acoustic communication systems are often highly variable. The degree of variation is often so great that few, if any, substantive generalizations hold for all populations in a species.

Within my dissertation, I explore the interplay of variation and uniformity in three vocal learning species: budgerigars (Melopsittacus undulatus), …

The Development Of Socio-Sexual Behavior In Beluga Whales (Delphinapterus Leucas), Malin K. Lilley

Dissertations

The reproductive success of the beluga whale is critical for a species facing extinction in its endangered Cook Inlet, Alaska population. To date, little is known about the mating behavior of these whales in wild populations. On the other hand, observations of beluga whales in human care allow researchers to better understand many aspects of their daily lives and life histories that are difficult to assess in wild populations. Thus far, a catalog of socio-sexual behavior has been established based on observations of belugas; however, the developmental trajectory of socio-sexual behavior is not well-understood. The present study explored how socio-sexual …

Bottlenose Dolphin (Tursiops Truncatus) Vocal Responses To Sonar And Spectrally Pink Background Noise, Maria Zapetis

Dissertations

As human populations rise, the level of man-made noise increases globally. Naval sonar and boat traffic are underwater sound sources of particular concern to marine mammal welfare. To better understand the impact of these noise increases on cetaceans, studies can explore animals’ behavioral changes in response to noise. Studies have investigated the ‘dose-response’ relationship between the received sound pressure level of sonar signals and the behavior of cetaceans in the wild, but exposure studies in controlled environments are limited. The studies in this dissertation examined bottlenose dolphin vocal modifications during various experimental noise treatments. Acoustic recordings previously obtained for bottlenose …

Farm Animal Cognition—Linking Behavior, Welfare And Ethics, Christian Nawroth, Jan Langbein, Marjorie Coulon, Vivian Gabor, Susan Oesterwind, Judith Benz-Schwarzburg, Eberhard Von Borell

Social Cognition Collection

Farm animal welfare is a major concern for society and food production. To more accurately evaluate animal farming in general and to avoid exposing farm animals to poor welfare situations, it is necessary to understand not only their behavioral but also their cognitive needs and capacities. Thus, general knowledge of how farm animals perceive and interact with their environment is of major importance for a range of stakeholders, from citizens to politicians to cognitive ethologists to philosophers. This review aims to outline the current state of farm animal cognition research and focuses on ungulate livestock species, such as cattle, horses, …

Perceptual Lateralization Of Vocal Stimuli In Goats, Luigi Baciadonna, Christian Nawroth, Elodie F. Briefer, Alan G. Mcelligott

Communication Skills Collection

Functional asymmetries, for example, the preferential involvement of 1 brain hemisphere to process stimuli, may increase brain efficiency and the capacity to carry out tasks simultaneously. We investigated which hemisphere was primarily involved in processing acoustic stimuli in goats using a head-orienting paradigm. Three playbacks using goat vocalizations recorded in different contexts: food anticipation (positive), isolation (negative), food frustration (negative), as well as 1 playback involving dog barks (negative) were presented on the left and right sides of the test subjects simultaneously. The head-orienting response (left or right) and latency to resume feeding were recorded. The direction of the head-orienting …

Object Permanence In Asian Elephants (Elephas Maximus), Dalia Miller

Theses and Dissertations

This study investigated object permanence in Asian elephants (Elephas maximus) using visible and invisible test paradigms with single and multiple object displacements. Elephants were predicted to succeed, demonstrating a capacity for object permanence and for using vision in a cognitive task. Study outcomes supported these predictions.

Dolphins In Space: Quantifying The Relative Positions Of Bottlenose Dolphins (Tursiops Truncatus), Megan S. Mcgrath

Theses and Dissertations

Bottlenose dolphins (Tursiops truncatus) are socially sophisticated mammals with high fission-fusion dynamics and complex communication. The relative positioning of individual dolphins as they swim within their social group may aid in the expression of social roles. This study sought to quantify relative positioning in a small social group of female bottlenose dolphins at the National Aquarium in Baltimore that included two mother-daughter pairs, maternal and paternal half-sisters, a half-aunt and niece, and one unrelated female. We devised a method for scoring relative positioning in three dimensions. We found that the two mothers and their juvenile and adult daughters …

A Global Reassessment Of Solitary-Sociable Dolphins, Laetitia Nunny, Mark P. Simmonds

Personality Collection

Dolphins are typically regarded as highly social animals. However, some individuals live apart from their own species and may come to socialize with people through a recognized series of stages which are presented and expanded on in this paper. The term “solitary-sociable dolphins” has been used to describe these animals and such individuals have been identified from several different species and reported in many parts of the world. In many instances, the interactions with people that may follow their original isolation, and which typically become more intense over time, have created situations where the welfare of the animal has been …

Elevated Sensitivity To Tactile Stimuli In Stereotypic Horses, Sabrina Briefer Freymond, Déborah Bardou, Sandrine Beuret, Iris Bachmann, Klaus Zuberbühler, Elodie Briefer

Personality Collection

Although stereotypic behaviors are a common problem in captive animals, why certain individuals are more prone to develop them remains elusive. In horses, individuals show considerable differences in how they perceive and react to external events, suggesting that this may partially account for the emergence of stereotypies in this species. In this study, we focused on crib-biting, the most common stereotypy displayed by horses. We compared how established crib-biters (“CB” = 19) and normal controls (“C” = 18) differed in response to a standard “personality” assessment test battery, i.e., reactivity to humans, tactile sensitivity, social reactivity, locomotor activity, and curiosity …

The Impacts Of The City And County Of Denver’S Breed Specific Legislation, Sloane M. Hawes, Devrim Ikizler, Katy Loughney, Justin F. Marceau, Philip Tedeschi, Kevin N. Morris

Speciesism and Breed Discrimination Collection

In August of 1989, the City and County of Denver, CO, USA enacted legislation that prohibits the presence of all “pit bull” type dogs (PBTD) (defined in Denver as: American Pit Bull Terrier, American Staffordshire Terrier, or Staffordshire Bull Terrier) within the city limits. In the 30 years the “pit bull ban” has been in place, the City and County of Denver and its animal control agency, Denver Animal Protection, have committed substantial resources to removing PBTDs from the community, including patrolling communities and/or responding to complaints made by neighbors, conducting thorough breed evaluations of suspected PBTDs, and kenneling PBTDs …

A Non-Selective Serotonin Antagonist Promotes Rapid Habituation In The Terrestrial Hermit Crab, Kirandeep Sumra, W. David Stahlman

Psychological Science Articles

Research has indicated that serotonin (5-HT) modulates non-associative learning in a variety of invertebrate species. Recent work has demonstrated that the terrestrial hermit crab is a suitable animal model for non-associative learning phenomena, including habituation, sensitization, and dishabituation. We examined the potential role of a non-selective 5-HT antagonist, methysergide, in non-associative learning in the hermit crab. We administered methysergide prior to delivering repeated stimulus presentations of a looming visual predator. We found evidence for more rapid habituation relative to a control condition in which crabs did not receive the drug. These results indicate a role for 5-HT in the defensive …

Probability Discounting Of Lewis And Fischer 344 Rats: Strain Comparisons At Baseline And Following Acute Administration Of D-Amphetamine, Jenny E. Ozga

Graduate Theses, Dissertations, and Problem Reports (ETD)

Risky choice can be defined as choice for a larger, uncertain reinforcer over a smaller, certain reinforcer when choosing the smaller alternative maximizes reinforcement. Risky choice is studied using various procedures in the animal laboratory; one such procedure is called probability discounting. There are many variables that contribute to risky decision-making, including biological and pharmacological determinants. The present study assessed both of these variables by evaluating dose-response effects of d-amphetamine on risky choice of Lewis (LEW) and Fischer 344 (F344) rats. The probability-discounting procedure included discrete-trials choices between one food pellet delivered 100% of the time and three food …

The Philosopher's Journey: A Chapter In Kindness And Animals, Vaughn E. Sayers

UNF Undergraduate Capstone Projects and Honors Theses

We each are presented with a choice; do we remain in the cave of ignorance or embark on the philosopher’s journey. Your choice will determine the way in which you interpret this paper. However, I will confidently make the assumption that you, like myself, desire to embrace an existence guided by the light of wisdom. This thesis is one of many chapters in the philosopher’s journey, dealing with animals and (cutting through the jargon) kindness. I have found that a lot of scholarship on animal ethics acknowledges a truth, but does not acknowledge that the application of such a truth …

Reconciling Just Preservation, Shelley M. Alexander

Animal Sentience

Treves et al.’s target article can play an important role in reconciling the needs of future generations and non-human animals in conservation. Human capacities are adequate for interpreting and defining many non-human animal needs. Worldviews are more complex, however, and conservation science, like the target article itself, suffers from a lack of diversity and inclusiveness. This may pose practical impediments to realizing just preservation.

Why Factual Appeals About The Abilities Of Sheep May Fail, Sarah Gradidge, Magdalena Zawisza

Animal Sentience

Marino & Merskin (2019) express hope that providing people with positive information about the abilities of sheep (factual appeals) will improve perceptions of them and thus improve their welfare. However, these factual appeals can, and do, fail to change perceptions of animals. This commentary considers why and when factual appeals fail, and with whom they may be effective.

Social Cognition In Sheep: Welfare Implications, Keith M. Kendrick

Animal Sentience

More research has been carried out on social cognition in sheep than in other farm animal species. Although this has often been featured widely in the media, there is still limited public awareness of it. Marino & Merskin’s review is therefore both important and timely. In my commentary, I focus primarily on what has been established about the complexity of sheep social cognition, at the level of both brain and behavior, and on some of these findings for sheep welfare.

Anthropocentrism: Practical Remedies Needed, Helen Kopnina

Animal Sentience

It is true that one of the harmful consequences of creating categories where one group is unique and superior to others is that it justifies discriminating against the inferior groups. And outright abuse of nonhuman animals is indeed morally unjustifiable. But what is to be done about it?

A Behaviorist Approach To Sheep Cognition, Intelligence, And Welfare, Lindsay R. Mehrkam

Animal Sentience

Marino & Merskin’s review sheds light on the complexity of the mind, learning, and cognition of sheep. Readily observable behavior has value in its own right for promoting the well-being of animals. A behavior-analytic approach can add substantially to the understanding of sheep as individuals as well as their learning capacities. The findings can also be applied to arranging their environments to promote their well-being as well as behavioral change in those responsible for their care and management.

Sentience Is The Foundation Of Animal Rights, Michael L. Woodruff

Animal Sentience

Chapman & Huffman argue that the cognitive differences between humans and nonhuman animals do not make humans superior to animals. I suggest that humans have domain-general cognitive abilities that make them superior in causing uniquely complex changes in the world not caused by any other species. The ability to conceive of and articulate a claim of rights is an example. However, possession of superior cognitive ability does not entitle humans to superior moral status. It is sentience, not cognitive complexity, that is the basis for the assignment of rights and the protections under the law that accompany them.

Measuring Glutamate And Oxygen In Brain Reward Circuits In Animal Models Of Cocaine Abuse And Decision-Making, Seth Richard Batten

Theses and Dissertations--Psychology

Drug-specific reward and associated effects on neural signaling are often studied between subjects, where one group self-administers drug and a separate group self-administers a natural reinforcer. However, exposure to drugs of abuse can cause long-term neural adaptations that can affect how an organism responds to drug reward, natural reward, and their reward-associated stimuli. Thus, to isolate drug-specific effects it is important to use models that expose the same organism to all of the aforementioned. Multiple schedules provide a means of dissociating the rewarding effects of a drug from the rewarding effects of food within a single animal. Further, drug users …

Effects Of A Voluntourism Experience On Perceptions And Attitudes Toward Environmental Sustainability And Science, Mireille Gonzalez

All Master's Theses

The current study explored the impact of a volunteer tourism experience at a community-based conservation (CBC) organization on volunteer perceptions, attitudes, and values toward conservation, the environment, and science. The Madagascar Research and Conservation Institute (MRCI) is a CBC organization that utilizes volunteers as a data collection resource and workforce for conservation and community outreach initiatives. The current study analyzed data from volunteer experience evaluations (VEE), which included pre- and post-experience self-report surveys comprised of qualitative and quantitative response sections, completed by 45 voluntourists over a three-month span. The quantitative findings indicate that the voluntourist experience improved participants’ self-reported attitudes …

Psychologists' Use Of Dogs In Psychotherapy: A Therapeutic Exploration, Christine A. Treece

Antioch University Dissertations & Theses

The current fund of literature documents the many benefits of using dogs as adjunct healing agents for both physical and psychological ailments. Despite the ever-growing body of research about dogs as adjunct interventions, there is a meager amount of information available about clinician’s experience of bringing their dogs to work with them. This dissertation is an in-depth exploration of six psychologists licensed in the state of Washington who brought their dogs with them to work. Each participant’s interview was analyzed using Interpretative Phenomenological Analysis. From their interviews, nine primary themes were identified: Reason for the Acquisition of Dog, Nature of …

Prison-Based Dog Training Programs: Standard Protocol, Tyler M. Han, Erin Flynn, Joseph Winchell, Emily Gould, Jaci Gandenberger, Dana Barattin, Philip Tedeschi, Kevin N. Morris

Animal Training and Obedience Collection

Across the United States, the number of prison-based dog training programs (PDPs) has increased substantially over the past several years. Currently, there are approximately 255 PDPs across 47 states that operate in a variety of correctional settings; however, there is little information available on how to successfully develop and implement a PDP. As a result, the research team from the Institute for Human-Animal Connection (IHAC) has developed a standard protocol to help guide PDP development and implementation.

This report identifies common practices of PDPs and incorporates both general and context-specific recommendations that were gathered from interviews with PDP staff, relevant …

Demographics Regarding Belief In Non-Human Animal Sentience And Emotional Empathy With Animals: A Pilot Study Among Attendees Of An Animal Welfare Symposium, Amelia Cornish, Bethany Wilson, David Raubenheimer, Paul Mcgreevy

Societal Attitudes Toward Animals Collection

Attitudes to animals are linked to beliefs about their ability to experience pain and suffering, their cognition, and their sentience. Education and awareness-raising play a pivotal role in increasing society’s consideration of non-human animal welfare. The current pilot study explores the attitudes towards animal welfare among a unique population of people who attended an animal welfare symposium at the University of Sydney. It involved administration of a validated questionnaire that assessed attitudes to animals; specifically exploring participants’ (n = 41) beliefs about the sentience of animals and their emotional empathy with animals. The resultant data revealed significant associations between participants’ …

Looking On The Bright Side Of Livestock Emotions—The Potential Of Their Transmission To Promote Positive Welfare, Luigi Baciadonna, Sandra Duepjan, Elodie Briefer, Mónica Padilla De La Torre, Christian Nawroth

Emotion Collection

Emotions can be defined as an individual’s affective reaction to an external and/or internal event that, in turn, generates a simultaneous cascade of behavioral, physiological, and cognitive changes. Those changes that can be perceived by conspecifics have the potential to also affect other’s emotional states, a process labeled as “emotional contagion.” Especially in the case of gregarious species, such as livestock, emotional contagion can have an impact on the whole group by, for instance, improving group coordination and strengthening social bonds. We noticed that the current trend of research on emotions in livestock, i.e., investigating affective states as a tool …
