On Neglected Taxa: Protostomes And The Evolution Of Myelination, Michaella P. Andrade, Charles Morphy D. Santos

Animal Sentience

Understanding the evolution of nervous and sensory systems in animals is key to understanding the distribution of animal sentience. However, the use of model organisms – mostly vertebrates, and especially mammals – often biases comparative analyses. Sneddon et al. (2018a,b) point out that using nonhuman animals as models helps us better understand the multifaceted aspects of animal pain and sentience. Several concerns need to be considered in dealing with model organisms. Here we discuss how models that are unrepresentative phylogenetically influence hypotheses about the evolution of the myelination in animals. Greater effort is needed to escape “vertebrate-centrism” in evolutionary research.

Investigating The Interaction Between Memory Recall Content And Savoring Interventions On Openness, Caroline V. Young

Electronic Theses and Dissertations

Openness is generally characterized by a stark curiosity for novel experiences and the ability to flexibly shift one’s attention and thinking processes to appreciate differing perspectives. Research suggests openness is a personal resource in terms of helping individuals effectively regulate emotions, cope with stress, and socialize with diverse populations. However, it is unknown what interventions specifically lead to an increase in openness. Positive affect appears to be associated with openness, yet the mechanisms by which positive affect promotes openness remain unclear. It is possible savoring, the ability to maintain and extend positive affect, may play an important role in clarifying …

“I Am Not An Animal”, Lori Marino

Animal Sentience

The answer to Chapman & Huffman’s question — “Why do we want to think humans are different?” — lies in the work of Ernest Becker and the social psychology literature known as Terror Management Theory, according to which our deep anxiety about animality and death can drive our need to feel superior to the other animals.

The Effects Of Mood On Empathy, Openness To Diversity, Attitudes, And Willingness To Help Marginalized Groups, Angela J. Adams

Electronic Theses and Dissertations

Members of marginalized groups such as lesbian women and gay men are often at an increased risk of threat or harm compared to their heterosexual counterparts. They may experience prejudice in the form of discrimination and stigma related behaviors. Due to the stigma lesbian women and gay men face throughout various stages of their lives, it is important to examine and discover which factors increase more acceptance and empathy. Additionally, it is important to examine ways to increase positive regard and reduce discrimination in order to promote psychological and overall wellbeing for lesbians and gay men. Given what we know …

Moderating Effects Of Posttraumatic Growth On Suicidal Ideation After Combat Exposure, Matthew A. Strader

Electronic Theses and Dissertations

The suicide rate in the United States has risen since 1999 (Curtin, Warner, & Hedegaard, 2016). This increase may be a distinct problem for military service members who may have an additional risk through combat exposure (Bryan et al., 2015). There is a need to identify protective factors for suicide broadly and specifically for military service members and veterans. There is emerging evidence that posttraumatic growth may be a protective factor for suicide ideation possibly buffering the effects of combat exposure on suicide ideation (Bush, Skopp, McCann, & Luxton, 2011). The current study was designed to further examine the relationship …

Let Me Upgrade You: Common Measures In Public Health Accreditation Action Plans, Gurleen K. Roberts

Electronic Theses and Dissertations

Objectives: The purpose of this study is to understand the success rates for health departments pursuing and achieving accreditation in version 1.0 and 1.5 of the Public Health Accreditation Board (PHAB) standards and measures. During the accreditation process, health departments that present performance gaps are asked to complete an Action Plan to specify how they plan to improve to meet the desired conformity. This study will highlight specific measures that are often included in Action Plans so that health departments pursuing accreditation can be better prepared to address these common pitfalls.

Methods: This study is a non-experimental, secondary …

Far More To Sheep Than Meets The Casual Eye, Bernard Rollin

Animal Sentience

Marino & Merskin’s survey of the cognitive and social capacities of sheep is an eye-opener about the individuality and emotionality of this most maligned of all farm animals. My own eyes had already been opened by an adopted orphaned lamb, so much more like a dog as a companion animal than the mindless robot I had been conditioned to expect. I am morally certain that Marino & Merskin’s survey will have a similar effect on readers open to changing their minds.

Applied Cognition Research To Improve Sheep Welfare, Kristina Horback

Animal Sentience

If a change is going to occur in the care and management of domestic sheep, there needs to be a collaborative effort across many disciplines. This review by Marino & Merskin of the literature on cognitive processing in domestic sheep is limited by the inherent bias of the authors, including the impracticable goal of eliminating sheep production. Animal welfare concerns about the management of commercial sheep are valid; however, in order to make a difference, we need to develop an application for this knowledge about cognitive abilities in sheep.

Our Disparaging View Of Sheep Is Indeed Based On Cognitive Inadequacy: Unfortunately, It’S Ours, Hank Davis

Animal Sentience

Additional data, such as those surveyed by Marino & Merskin, are unlikely to change our perception of sheep. Arguably, the problem lies deeper than insufficient information. There are indeed cognitive deficits at the core of the problem, but they reside in Homo sapiens, not sheep. Judgmental biases that originated in the Pleistocene age have been over-extended in the modern world and result in unreasoning discriminative practices including speciesism. “Ism’s” run deep and the more an “other” looks and acts like us, the more respect we give it. Sheep do not prosper as “individual sentient beings” under such a heuristic.

Science, Social Critique, And The Need For Ethics, Peter Woodford, Alecia Carter

Animal Sentience

Marino & Merskin’s target article on the cognitive and psychological capacities of sheep commendably aims to use science to critique human practice. However, the article fails to make specific recommendations about how human-sheep relations should change going forward. We also underscore two problematic assumptions highlighted by other commentators: (1) that cognitive complexity is important to the case for the moral status of non-human animals and (2) that the way humans use and treat animals is caused by our conception of animals’ capacities. Scientists should engage more with philosophy and ethical theory to articulate the implications of animal capacities for human …

Cognitive Dissonance About Sheep Cognition And Consumption, Catia Correia Caeiro

Animal Sentience

Sheep are perceived as mere resources under the massive demand of the food and wool industry. Evidence that sheep cognition is comparable to that of other species may inspire reflection on sheep consumption. Dogs may be a promising comparison species.

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.

Effects Of Mental Health Programs On School Violence, Lillian R. Gray

Electronic Theses and Dissertations

Bullying, defined as any unwanted aggressive behavior(s) by another youth or group of youths who are not siblings or current dating partners that involves an observed or perceived power imbalance and is repeated multiple times or is highly likely to be repeated, is becoming an epidemic in our schools, with rates of victimization rising (Donegan, 2012). This thesis examines mental health programs already established within schools, as well as schools where students do not have access to mental health resources and compares the amount of violence that is perpetrated within these schools. Next, this study explores the relationship between bullying …

The Bioarchaeology Of The Tugalo Site (9st1): Diet, Disease, And Health Of The Past, Nompumelelo Beryl Hlophe

Electronic Theses and Dissertations

The Tugalo site is a prehistoric and early historic Native American site located in northeast Georgia along the upper Savannah River basin, near the junction of Toccoa Creek and the Tugalo River. According to archaeological materials analyzed from the site it was occupied from ca. A.D. 1100 to 1600 (Anderson et al. 1995). Although archaeological investigations of the site revealed basic characteristics of its chronology and architecture, very little analysis and reporting of the skeletal remains from Tugalo has been completed. By analyzing data collected by Williamson (1998) concerning the age and sex of the burials, the presence or absence …

The Effects Of Ses Stereotypes On Hurricane Decision Making, Alexandria D. Booth

Electronic Theses and Dissertations

Despite the severe and often costly consequences associated with severe weather instances, there is a continuing problem with noncompliance to weather warnings. This issue is pervasive, and research has shown a number of factors that are related to weather response (Joslyn & LeClerc, 2013). Further, individuals of a low socioeconomic status (SES) are often disproportionately impacted by severe weather instances, such as hurricanes (Elliot & Pais, 2006). Past research has shown that individuals of a low education level do not understand some aspects (e.g., numerical uncertainty) of a weather warning, suggesting that weather warnings may not be accessible for all …

Does Enhancing Mind Perception Affect Conspiracy Belief?, Jorge R. Noguera - Sepulveda

Electronic Theses and Dissertations

This study was conducted to determine the effectiveness of a novel mind perception manipulation. Mind perception is currently theorized to be an essential aspect of a number of human social psychological processes. Thus, a successful manipulation would allow for the causal study of those processes. This manipulation was created in an attempt to explore the downstream impact of mind perception on the endorsement of conspiracy theories. Conspiracy theories are steadily becoming more and more prominent in social discourse. Endorsement of conspiracy theories are beginning to show real world ramifications such as a danger to human health (e.g., in the anti-vaccination …

Octopus Umwelt Or Umwelten?, Luis H. Favela

Animal Sentience

Even if its intelligent behaviors are the product of decentralized control systems, Mather argues that the octopus has an “Umwelt,” and, thus, a mind. I argue that Umwelt does not provide a conceptual basis for understanding the octopus as having a mind. First, Umwelt does not refer only to an organism’s perceptual abilities. Second, in providing evidence for decentralized control systems that underlie intelligent behaviors, Mather makes a case against an octopus Umwelt. Instead, the octopus is more akin to a collection of systems, or Umwelten, than a single system with an Umwelt.

Octopus Minds Must Lead To Octopus Ethics, Barbara J. King, Lori Marino

Animal Sentience

Mather argues convincingly for the existence of minds in octopuses based largely on laboratory experiments. Many of these experiments are highly invasive and involve mutilation and death. Moreover, octopuses are now being hailed as a “new model” for biological research and are being enthusiastically bred in captivity, both for research and for food. We argue that the compelling evidence for mind in octopuses must be accompanied by intense scrutiny of the ethics that shape how we treat them and that the intrinsic value of their individual lives must be recognized.

The Perfecting Of The Octopus, Ila France Porcher

Animal Sentience

Cephalopods split away from the phylogenetic tree about half a billion years ago, and octopus evolution has been accelerated by an extremely low survival rate. This helps explain why this unusual animal presents qualities found in no other. It has a radially organized nervous system with a processing centre for each of its eight tentacles. Yet, although this might suggest that each tentacle has its own centre of consciousness, it remains just one animal, with one mouth to feed, and one life to lose, and it behaves as if it is centrally controlled. Its capacity for a range of intelligent …

‘Mind’ Is An Ill-Defined Concept: Considerations For Future Cephalopod Research, Alexandra Schnell, Giorgio Vallortigara

Animal Sentience

Scientific discussions about the ‘mind’ of an octopus are empirically vacuous and should be confined to folk psychology. This form of labelling is unhelpful for science and should be replaced by specific mechanistic accounts of behavior and associated neural structures, which are amenable to rigorous scientific investigation. Mather provides a detailed review of octopus behavior, but rather than making unquantifiable assumptions about what orchestrates octopus behavior, efforts should focus on investigating cognitive mechanisms that can be measured. In this commentary, we outline two lines of research that include quantifiable methods to facilitate a more robust understanding of cephalopod behaviors and …

The Octopus Mind: Implications For Cognitive Science, Sidney Carls-Diamante

Animal Sentience

Mather consolidates the case for octopus mind and how it may be structured, shifting the starting point of inquiry from “If octopuses had minds, what would they be like?” to “What is the mind of an octopus like?”.

Octopus Sentience: Three Criteria, Alix Noël-Guéry

Animal Sentience

The first question to ask is whether octopuses are sentient, so that, if so, they can be protected. Three consensual criteria to evaluate animal sentience can be applied to the octopus. Octopuses meet all three of them.

The Effects Of School Disciplinary Policies On Violence, Delinquency, And Disorder, Ernest E. Zittrouer Iii

Electronic Theses and Dissertations

The occurrence of violent and disruptive behavior in schools has been present throughout most of American educational history. The disciplinary policies established to address these behaviors have changed over time, becoming only more severe. The deterrent effect these policies were intended to produce has seen to be minimal, and despite a reduction in violent school victimization since the mid-1990s, schools continue to rely on these harsh policies (Skiba, 2014). This study examines the relationship between incident counts and discipline action counts for Georgia public schools (N = 2,150) for the 2017-2018 academic school year. This research utilizes negative binomial regression …

Are Chronic Inflammatory Diseases Associated With Trauma Exposure And Gender? An Empirical Analysis Of Self-Reported Trauma And Health Histories Of Men And Women, Meghan Lacienski

Electronic Theses and Dissertations

A growing body of research indicates an association between trauma, inflammation, and chronic inflammatory disease; however, the mechanisms of this relationship are not fully understood, and the salience of potential risk factors, such as cumulative effects of trauma, trauma type, and gender, remain unclear. Trauma is associated with poor mental and physical health, such as PTSD, depression, and chronic inflammatory conditions, and this association may be stronger when certain risk factors are considered (Brody, Pratt, & Hughes, 2018; Groer, Kane, Williams, & Duffy, 2014; Husky, Mazure, & Kovess-Masfety, 2018; Kilpatrick et al., 2013). For example, sexual trauma and multiple traumatic …

When Pets Become Pests: The Role Of The Exotic Pet Trade In Producing Invasive Vertebrate Animals, Julie I. Lockwood, Dustin J. Welbourne, Christina M. Romagosa, Phillip Cassey, Nicholas E. Mandrak, Angela L. Strecker, Brian Leung, Oliver C. Stringham, Bradley Udell, Diane J. Episcopio-Sturgeon, Michael F. Tlusty, James Sinclair, Michael R. Springborn, Elizabeth F. Plenaar, Andrew L. Rhyne, Reuben Keller

Environmental Science and Management Faculty Publications and Presentations

The annual trade in exotic vertebrates as pets is a multi-billion- dollar global business. Thousands of species, and tens of millions of individual animals, are shipped both internationally and within countries to satisfy this demand. Most research on the exotic pet trade has focused on its contribution to native biodiversity loss and disease spread. Here, we synthesize information across taxa and research disciplines to document the exotic pet trade’s contribution to vertebrate biological invasions. We show recent and substantial worldwide growth in the number of non-native animal populations introduced via this invasion pathway, which demonstrates a strong potential to increase …

Floodplains Provide Important Amphibian Habitat Despite Multiple Ecological Threats, Meredith Holgerson, Adam Duarte, Marc P. Hayes, Michael J. Adams, Julie A. Tyson, Keith A. Douville, Angela L. Strecker

Environmental Science and Management Faculty Publications and Presentations

Floodplain ponds and wetlands are productive and biodiverse ecosystems, yet they face multiple threats including altered hydrology, land use change, and non-native species. Protecting and restoring important floodplain ecosystems requires understanding how organisms use these habitats and respond to altered environmental conditions. We developed Bayesian models to evaluate occupancy of six amphibian species across 103 off-channel aquatic habitats in the Chehalis River floodplain, Washington State, USA. The basin has been altered by changes in land use, reduced river–wetland connections, and the establishment of non-native American bullfrogs (Rana catesbeiana = Lithobates catesbeianus) and centrarchid fishes, all of which we hypothesized could …

A Longitudinal Investigation Of Interpersonal Trauma Exposure, Posttraumatic Stress Disorder, And Cannabis Use Phenotypes Among College Students, Terrell A. Hicks

Theses and Dissertations

College students have an increased risk for cannabis use, trauma exposure, and posttraumatic stress disorder (PTSD). Cannabis use disorder (CUD) and PTSD comorbidity is high, and given the negative consequences of the comorbidity (e.g., poor academic outcomes), there is a need to understand comorbid CUD-PTSD etiology. Two primary etiologic models exist: self-medication (i.e., PTSD à CUD) and high-risk (i.e., CUD à PTSD) hypotheses. This study 1) examined the prevalence and predictors of cannabis use and interpersonal trauma (IPT) exposure; 2) investigated the relationship between cannabis use and IPT; and 3) examined cannabis use, IPT, and PTSD through mediational self-medication and …

Anthropomorphism Is The First Step, Marthe Kiley-Worthington

Animal Sentience

Individuals have intentions, beliefs and choices. This sense of “personhood” has been known and used for centuries by those who have dealt professionally with any nonhuman mammal. All mammals have a lot in common physically and mentally. The first step toward understand another species’ point of view is anthropomorphism.

Phenotypic Similarity And Moral Consideration, S. Brian Hood, Sophia Giddens

Animal Sentience

Identifying specific traits to justify according differential moral status to humans and non-human animals may be more challenging than Chapman & Huffman suggest. The reasons for this also go against their recommendation that we ought to attend to how humans and non-humans are similar. The problem lies in identifying the moral relevance of biological characteristics. There are, however, other reasons for treating non-human animals as worthy of moral consideration, such as the Precautionary Principle.

Our Brains Make Us Out To Be Unique In Ways We Are Not, Matthew J. Criscione, Julian Paul Keenan

Animal Sentience

Humans have long viewed themselves in a favorable light. This bias is consistent with a general pattern of self-enhancement. Neural systems in the medial prefrontal cortex underlie this way of thinking, which, even when false, may be beneficial for survival. It is hence not surprising that we often disregard contrary evidence in believing ourselves superior.
