Where Is Pain In The Brain?, Marshall Devor

Animal Sentience

Key argues that fish cannot experience pain based on (1) brain imaging in humans, (2) consequences of lesions and (3) direct brain stimulation. Imaging indeed shows that pain-relevant signals reach the cortex, but not that they underlie the subjective experience of pain. Lesions and stimulation data are more to the point, but Key paints an idiosyncratic and misleading picture of their effects. S1 and S2 ablation does not eliminate evoked or spontaneous pain, although there may be up- or down-modulation. Likewise, stimulation of pain-associated cortical areas rarely induces pain, and pain almost never occurs at the onset of epileptic seizures. …

Fish Pain: Would It Change Current Best Practice In The Real World?, B. K. Diggles

Animal Sentience

Much of the “fish pain debate” relates to how high the bar for pain should be set. The close phylogenetic affinities of teleosts with cartilaginous fishes which appear to lack nociceptors suggests caution should be applied by those who seek to lower the bar, especially given the equivocal and conflicting nature of the experimental data currently available for teleosts. Nevertheless, even if we assume fish “feel pain,” it is difficult to see how current best practice in aquaculture would change. This is because of the need to avoid stress at all stages of the rearing process to optimize health, growth …

Pain-Capable Neural Substrates May Be Widely Available In The Animal Kingdom, Edgar T. Walters

Animal Sentience

Neural and behavioral evidence from diverse species indicates that some forms of pain may be generated by coordinated activity in networks far smaller than the cortical pain matrix in mammals. Studies on responses to injury in squid suggest that simplification of the circuitry necessary for conscious pain might be achieved by restricting awareness to very limited information about a noxious event, possibly only to the fact that injury has occurred, ignoring information that is much less important for survival, such as the location of the injury. Some of the neural properties proposed to be critical for conscious pain in mammals …

Going Beyond Just-So Stories, Brian Key

Animal Sentience

Colloquial arguments for fish feeling pain are deeply rooted in anthropometric tendencies that confuse escape responses to noxious stimuli with evidence for consciousness. More developed arguments often rely on just-so stories of fish displaying complex behaviours as proof of consciousness. In response to commentaries on the idea that fish do not feel pain, I raise the need to go beyond just-so stories and to rigorously analyse the neural circuitry responsible for specific behaviours using new and emerging technologies in neuroscience. By deciphering the causal relationship between neural information processing and conscious behaviour, it should be possible to assess cogently the …

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.

Breaking The Silence: The Veterinarian’S Duty To Report, Martine Lachance

Animal Sentience

Animals, like children and disabled elders, are not only the subjects of abuse, but they are unable to report and protect themselves from it. Veterinarians, like human physicians, are often the ones to become aware of the abuse and the only ones in a position to report it when their human clients are unwilling to do so. This creates a conflict between professional confidentiality to the client and the duty to protect the victim and facilitate prosecution when the law has been broken. I accordingly recommend that veterinarian associations make reporting of abuse mandatory.

Behaviors Of A Captive Coenobita Clypeatus In The Presence Of Varying Light Stimuli, Larry D. Fort, Ingrid K. Tulloch

Modern Psychological Studies

Coenobita clypeatus, or the purple pincher, is a terrestrial hermit crab and common pet in the United States. Modern behavioral studies have waned since the early 2000s; we therefore sought to characterize the behavior of a single captive C. clypeatus under varying light conditions. Frequency and duration of behaviors were studied in the presence of different light stimuli, along with weight monitoring. The crab was recorded for a set period of time every night with all conditions standardized except for light. The light stimulus alternated between no light, blue light, and red light. The case study revealed a significant increase …

Examining The Effect Of Caffeine And Technology On Adolescent Sleep, Kaci D. Clark

Masters Theses

The current study expands upon existing sleep research by assessing adolescent caffeine consumption and technology use around bedtime and group differences in caffeine consumption and technology use in regard to sleep onset time, duration and quality, as well as symptoms of delayed sleep phase syndrome (DSPS). Participants, ranging in age from 13 to 18 years, were recruited from two Midwestern high schools and one junior high school. Online survey software was used to capture adolescents' self-reported caffeine consumption, technology use, and sleep. Adolescents who drank more caffeine did not spend significantly more time using technology at night, nor did they …

Evaluation Of The Expectancy Challenge Alcohol Literacy Curriculum (Ecalc) For High School Students, Alyssa Dietz

Electronic Theses and Dissertations

Prevention efforts targeted at children and adolescents are important because alcohol consumption contributes to the three leading causes of death in this among 12-20 year-olds: unintentional injury, homicide, and suicide. Research on the causes of alcohol misuse traditionally focused on pharmacological and genetic explanations, but models have expanded to include cognitive processes in the development of alcohol use patterns. Alcohol expectancies, or beliefs about the effects of alcohol, are an important influence on drinking behavior. Expectancies exist prior to the initial drinking experience, predict the onset of alcohol consumption, differentiate both children and adults in terms of light- and heavy-drinking …

Mothers' History Of Child Maltreatment And Regulation Abilities: Interactions Among Young Children's Temperament, Attachment, And Maltreatment Potential, Jayme Puff

Electronic Theses and Dissertations

Given the impact that parents' and young children's characteristics have on the potential for child maltreatment, the present study sought to examine how mothers' ratings of their own childhood maltreatment, their psychological symptoms, their regulation abilities (i.e., emotion regulation, reflective functioning, attributions, and coping with young children's negative emotions), and their perceptions of their young children's temperament were related to their narratives of their attachment relationships with their young children and their child maltreatment potential. As part of this study, 54 mothers rated themselves and their young children on the aforementioned variables. Binary logistic hierarchical regression analysis suggested that mothers' …

Role Of Sleep In Exposure Therapy For Posttraumatic Stress Disorder In Oif/Oef Combat Veterans, Franklin Mesa

Electronic Theses and Dissertations

Exposure therapy is theorized to reduce posttraumatic stress disorder (PTSD) symptomatology by promoting habituation/extinction of fear responses to trauma-related cues. Empirical evidence indicates that emotional memory, including habituation/extinction learning, is enhanced by sleep. However, service members with combat-related PTSD often report disturbed sleep. In this study, quality of sleep and indicators of extinction learning were examined in veterans of recent wars who had completed an exposure-based PTSD intervention. Fifty-five participants were categorized into two groups based on self-reported quality of sleep: low sleep disruption severity (LSDS; N = 29) and high sleep disruption severity (HSDS; N = 26). Participants in …

The Longitudinal Relationship Between Moderate Alcohol Use And Cognitive Aging Among Older Adults., Danielle Herring

Electronic Theses and Dissertations

Cognitive aging appears inconsistent across cognitive domains, indicating that domains may not all decline at the same rate across individuals. Individual trajectories of cognitive aging can vary widely and are affected by numerous lifestyle and health factors. Alcohol use among older adults is known to confer both health risks, typically related to excessive use, and protective effects, often associated with moderate consumption. Moderate alcohol use has been linked with better cognitive functioning as well as a decrease in cardiovascular mortality and systemic inflammation, as compared to heavy or abstinent users. Given that extant research has identified C-reactive protein (CRP) as …

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.

Responses To Familiar And Unfamiliar Humans By Belugas (Delphinapterus Leucas), Bottlenose Dolphins (Tursiops Truncatus), & Pacific White-Sided Dolphins (Lagenorhynchus Obliquidens): A Replication And Extension, Heather M. Hill, Deirdre Yeater, Sarah Gallup, Sara Guarino, Steve Lacy, Tricia Dees, Stan A. Kuczaj Ii

Psychology Faculty Publications

Previous research has documented that cetaceans can discriminate between humans, but the process used to categorize humans still remains unclear. The goal of the present study was to replicate and extend previous work on the discrimination between familiar and unfamiliar humans by three species of cetaceans. The current study manipulated the familiarity and activity level of humans presented to 12 belugas (Delphinapterus leucas) housed between two facilities, five bottlenose dolphins (Tursiops truncatus), and six Pacific white-sided dolphins (Lagenorhynchus obliquidens) during free-swim conditions. Two measures of discrimination were coded from video recordings of each trial: …

Anger Maintenance And The Impact Of Shame, Attachment, And Experiential Avoidance, Ahva R. Mozafari

EWU Masters Thesis Collection

Prior to the present study, the relationships between attachment, shame, experiential avoidance, and anger had not been empirically evaluated. This study investigated the influence of shame and attachment style on anger and experiential avoidance. Additionally, this study also explored the differences between those with anxious and avoidant attachment styles and their experiences of anger, as well as their ability to confront emotions. It was hypothesized that the combination of attachment, shame, and experiential avoidance would be predictors of anger. Finally, it was hypothesized that shame experiences would mediate the relationships between attachment and anger as well as attachment and experiential …

Perceptions Of Immunizations As Health Prevention Among Female Mexican Immigrants In Oklahoma, Jennifer Doyle

Walden Dissertations and Doctoral Studies

Research on health prevention behaviors of Mexican immigrant mothers regarding immunizations has been limited. As of 2014, Hispanics or Latinos comprised 9.6% of the population of the state of Oklahoma and were the largest minority group within Oklahoma. This minority population has continued to grow at a rapid rate in Oklahoma. The purpose of this study was to explore the perceptions of immunizations held by Mexican immigrants who are mothers residing in Oklahoma. The aim of this study was to identify their perceived risk of contracting a vaccine-preventable disease if not immunized and knowledge of immunizations as a health prevention …

Attitudes Of Nigerian Mothers Toward Children With Autism Spectrum Disorder, Valentine Ntoo Chukwueloka

Walden Dissertations and Doctoral Studies

Autism spectrum disorder (ASD) is a form of developmental disability that affects many children in the U.S. and abroad. The Center for Disease Control (CDC) has indicated that 1 out of every 68 children is diagnosed with ASD in the United States. However, there was limited literature about the attitudinal dispositions of Nigerian mothers toward children with ASD and their lived experiences with a child with autism. The purpose of this qualitative study was to explore the attitudes of Nigerian mothers toward their children with autism. The theoretical foundation of this study was the variation of the social relational understanding …

Impact Of Positive Youth Development Services On Resilience Among Adjudicated Girls, Shaunette Roberta Byers Parker

Walden Dissertations and Doctoral Studies

Positive youth development (PYD) frameworks that guide PYD services suggest at-risk youth need to develop resiliency attitudes and resiliency skills in order to prevent long-term failure in their adult lives. This concept is based on multiple developmental theories that suggest increased levels of resiliency make it easier to navigate challenging situations. Adjudicated youth have faced a major setback in their short lives, yet they still have an opportunity to become successful and avoid additional jail time, if they are able to display a strong sense of resilience. Many youth development programs geared toward serving adjudicated youth, lack the appropriate structure …

Sexuality, Sexual Orientation, And Intellectual Developmental Disorder: A Parent's Perspective, Wendy Marie Kellon

Walden Dissertations and Doctoral Studies

A consistent gap in previous studies was sexuality education and sexual orientation, as well as how to disseminate the sexual education material in a format that would be useful to individuals with IDD, parents, and caregivers. This biographical study addresses the understanding of sexuality and sexual orientation of an individual with intellectual developmental disorder (IDD), as reported by his parents. Data were collected through face-to-face interviews, documents, and social media sites belonging to the participants. The theoretical framework for this study was social constructivism; a thematic analysis was used for data analysis. The six themes that emerged from this research …

Immigration's Impact On Emerging Mental Health Issues Among Kenyans In The Northeast United States, Jane Itumbi Kabuiku

Walden Dissertations and Doctoral Studies

Immigrants lose their unique psychosocial context when their experiences are subsumed under pan ethnic labels such as Hispanics, Latina/o, Asians or Africans. The stress from navigating different cultural contexts becomes problematic when immigrants operate within mainstream cultural norms that are in conflict with their traditional values. The number of Kenyan immigrants to the United States has steadily increased since the 1980s. The purpose of this descriptive phenomenological study was to study the lived experience of Kenyan immigrants by focusing on their integration experience and how the integration processes may have affected their mental health. Very few studies center on the …

Yuli's Story: Using Educational Policy To Achieve Cultural Genocide, Katrina Johnson Leon

University of the Pacific Theses and Dissertations

All children residing in the United States have the right to a quality education. At least that is our collective expectation. Through the lived experience of Yuli, a Native American woman from the Southwest, you will discover, due to her birth on a remote reservation, she was not given the same access to education you or I would expect. On Yuli’s reservation, the school system is managed by the Bureau of Indian Education (BIE). Rather than provide K-12 schooling, the BIE operates K-8 on her reservation and then Native youth who want to go to high school must move off-reservation. …

Examining The Psychological Adjustments Of Neurotypical Siblings Of Individuals With Autism Spectrum Disorder (Asd) And Determining The Efficiency Of Support Groups, Swathi Deo Sambatha

UROP Posters

Neurotypical siblings of individuals with behavioral disorders are reported to have complex, complicated psychological adjustments that vary significantly due to a multitude of sociodemographic factors. In addition, these children are at risk of mental health disorders and negative psychological symptoms. Support groups or extensive social support are known to increase intra-communication and create better sibling dynamics between the neurotypical and autistic siblings. This paper investigates such complications to the psychological adjustment of neurotypical siblings of individuals with autism spectrum disorder (ASD) and determines the implications of the utilization of support groups/social support. The analyzed trends and reportings of multiple studies …

The Effects Of Pet Ownership On Anxiety And Depression Among Trauma-Exposed College Students, Dung N. Nguyentran, Marlene A. Michniak, James J. Jung, Christine Q. Do

UROP Posters

Rates of anxiety and depression are prevalent in college students and can be attributed in part to stress and trauma-related events. However, studies suggest that pet ownership has the possibility of alleviating symptoms of anxiety, depression, negative emotions, and suicide. The purpose of this study was to determine the relationship between pet ownership and levels of anxiety and depression among those who have experienced a traumatic event. The sample was comprised of five hundred and forty-seven VCU students who completed an online survey from Spit for Science during their junior year. Linear regressions were performed to determine the nature and …

The Impact Of Survival Processing And Collaborative Inhibition On Memory Performance, Lindsey Hardin

Honors Theses

This study examines the effects of survival processing and collaborative inhibition on memory performance. The purpose of this research is to determine whether survival processing produced more accurate memory recall than pleasantness processing, as well as determine the impact of collaborative inhibition when compared to nominal groups. In this experiment, participants were given the instructions to rate a given list of words based on survival or pleasantness depending on which scenario they were assigned to. Then, the participants recalled the list of words in either collaborative groups or nominal groups. The results indicated that the survival condition did produce better …

Compassion Fatigue And Crisis Workers' Attitude To Work, Maria Adneza Loolo

Walden Dissertations and Doctoral Studies

Past research has revealed that mental health practitioners experience challenging reactions in the course of their professional interactions with traumatized clients in the clinical work setting. The demands of caring, without commensurate replenishment, deplete the practitioners' empathy and produces forms of apathy and indifference towards the suffering of others, known as compassion fatigue. This quantitative, exploratory, cross sectional study examined the predictive relationships between compassion fatigue and work attitudes in primary care physicians located in West Africa. The etiological model of compassion fatigue and constructivist self-development theory (CSDT) formed the conceptual framework for examining clinician responses to trauma-related experiences in …

Predictors Of Likeliness To Engage In Radical Animal Rights And Environmental Activism, Patsy Mckenzie

Walden Dissertations and Doctoral Studies

Radical animal rights and environmental activism is considered domestic terrorism under the Animal Enterprise Terrorism Act. Traditional models of terrorism purport that there is a path to radicalization that is influenced by an individual's sense of identity and ideological beliefs. Using collective identity theory and cognitive experiential self-theory as the framework, the purpose of this quantitative study was to examine whether social identity, cognitive processing mode, and ideological beliefs were predictors for engagement in radical animal rights and environmental activism. The Three Factor Model of Social Identity Scale, the Rational Experiential Inventory, and the Activism Orientation Scale were used to …

Everyday Problems With Executive Dysfunction And Impulsivity In Adults Recovering From Methamphetamine Addiction, Carilyn Ellis, William Hoffman, Sarah Jaehnert, Jane Plagge, Jennifer M. Loftis, Daniel Schwartz, Marilyn Huckans

Faculty Publications - Doctor of Psychology (PsyD) Program

Objectives

Compared with non-addicted controls (CTLs), adults in remission from methamphetamine addiction (MA-REM) evidence impairments on objective measures of executive functioning and impulsivity.

Methods

To evaluate the impact of these impairments in MA-REM adults, demographically matched groups (MA-REM, n=30; CTLs, n=24) completed objective and self-report measures of executive functioning and impulsivity.

Results

MA-REM adults demonstrated significantly (p < 0.050) greater objective and subjective problems with executive functioning and impulsivity.

Conclusions

These results suggest that adults in MA-REM are aware of their deficits and that these deficits have significant impact in everyday life.

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.
