Understanding Animal Suicide And Death Can Lead To Better End-Of-Life Care, Jessica Pierce

Animal Sentience

Peña-Guzmán’s target article on animal suicide will help inform end-of-life care for animals by emphasizing the need for a broad research focus on animal thanatology. Greater scientific understanding of the continuum of death-related awareness, experiences, and behaviors will help us improve veterinary care for animals at the end of life.

Complicated Grief, Teya Brooks Pribac

Animal Sentience

My commentary discusses complicated grief and the ensuing sense of helplessness that may lead to suicide. I close with a story about a pygmy pig.

Can Nonhuman Animals Commit Suicide?, David M. Peña-Guzmán

Animal Sentience

Many people believe that only humans have the cognitive and behavioral capacities needed for suicidal behavior, such as reflexive subjectivity, free will, intentionality, or awareness of death. Three counterarguments — based on (i) negative emotions and psychopathologies among nonhuman animals, (ii) the nature of self-destructive behavior, and (iii) the problem of model fidelity in suicide research — suggest that self-destructive and self-injurious behaviors among human and nonhuman animals vary along a continuum.

The Roles Of Individuals And Social Networking In A Small Group Of Domestic Horses At Pasture, C. Ricci-Bonot, Marthe Kiley-Worthington

Social Behavior Collection

100 h (500 horse h) of critically assessed observations where analysed from two pastural situations on decision making and social networking in a herd of 5 arab and arab x horses of the Druimghigha Stud, behaviourally studied since 1978. Roles such as decision maker (the oldest mare) or follower (the youngest filly) and the popularity of each individual from whom they chose to be near were analysed. Social netwok analysis indicated the centrality of an individual, cohesive bonds among 3 mares and a sub group of the filly and the gelding. A network closure towards the gelding was also illustrated, …

Getting To The Other Side, Debra Merskin

Animal Sentience

Marino’s comprehensive, detailed, and timely review provides clear evidence of the sentience of chickens and strong support for those wishing to challenge their exclusion from even the limited protections currently accorded to animals grown for food.

Sentience Does Not Require “Higher” Cognition, Giorgio Vallortigara

Animal Sentience

I agree with Marino (2017a,b) that the cognitive capacities of chickens are likely to be the same as those of many others vertebrates. Also, data collected in the young of this precocial species provide rich information about how much cognition can be pre-wired and predisposed in the brain. However, evidence of advanced cognition — in chickens or any other organism — says little about sentience (i.e., feeling). We do not deny sentience in human beings who, because of cognitive deficits, would be incapable of exhibiting some of the cognitive feats of chickens. Moreover, complex problem solving, such as transitive inference, …

Misperceiving And Underestimating The Ubiquitous Chicken, Carrie P. Freeman

Animal Sentience

Marino has provided an accurate and nuanced view about chickens’ complex capabilities as sentient individuals. I explore the implications of these findings for scholars as well as for activists in the protection of farmed animals.

Is Psychological Science Committing “Suicide” By Linguistic Muddling?, Roger K. Thomas

Animal Sentience

Beginning mainly with the “cognitive revolution” in psychology in the latter half of the 20^th century, psychological science has been committing “suicide” slowly via linguistic muddling. Peña-Guzmán’s target article is but one of thousands of cuts contributing to this death by “suicide.” Having said that, given the current state of affairs in animal cognition research, there is much to commend in Peña-Guzmán’s article. I leave that to others, however. This commentary explains how the suicide by muddling of psychological science is happening in general, with the understanding that it applies also to Peña-Guzmán’s target article.

On Assisted Suicide, Clark Glymour

Animal Sentience

What would be the moral implications of the capacity for suicide in nonhuman animals? Humans can be helped to end their lives if they no longer find them bearable. Should captive animals not be given the same possibility?

The Potential Of Epigenetics Research To Transform Conceptions Of Phenotype Development, David S. Moore

Pitzer Faculty Publications and Research

Epigenetics remains an exciting subdiscipline of biology, generating discoveries and insights about development. Because epigenetic phenomena can draw attention to the dynamic, interactional, and probabilistic nature of phenotype development, epigenetics research could hasten the demise of both nature-nurture debates and reductionist, genetically determinist perspectives on phenotype development. However, new data alone will not inevitably transform conceptualizations of phenotype origins, because it remains possible to assimilate epigenetic phenomena into traditional conceptual frameworks; epigenetic discoveries could even strengthen biologically determinist conclusions if traditional conceptualizations are retained. Although epigenetics will not force conceptual transformation, epigenetics research encourages the dismissal of the nature-nurture dichotomy …

Executive Control Goes To School: Implications Of Preschool Executive Performance For Observed Elementary Classroom Learning Engagement, Timothy D. Nelson, Jennifer Mize Nelson, Tiffany D. James, Caron A.C. Clark, Katherine M. Kidwell, Kimberly Andrews Espy

Department of Psychology: Faculty Publications

The transition to elementary school is accompanied by increasing demands for children to regulate their attention and behavior within the classroom setting. Executive control (EC) may be critical for meeting these demands; however, few studies have rigorously examined the association between EC and observed classroom behavior. This study examined EC in preschool (age 5 years, 3 months) as a predictor of classroom learning engagement behaviors in first grade, using a battery of performance-based EC tasks and live classroom observations in a longitudinal sample of 313 children. Multilevel modeling results indicated that stronger EC predicted more focused engagement and fewer task …

A Correlational Study Of Emotional Intelligence And Language Style Matching, Deprise M. Depass

Honors Undergraduate Theses

ABSTRACT

Individuals subconsciously convey emotions through language. The present study investigates the relationship between emotional intelligence (EQ) and language style matching (LSM). Emotional intelligence involves the ability to regulate, maintain, and express one’s emotions and to perceive the emotion of others. LSM involves the phenomenon that when individuals talk they tend to mimic each other’s word usage (Neiderhoffer & Pennebaker, 2002). The hypothesis of the present study is that individuals who are emotionally intelligent subconsciously match their language to their communication partner. Ten participants from the University of Central Florida’s Psychology Department were given an emotional intelligence test. The participants …

Origins Of Thalamic And Cortical Projections To The Posterior Auditory Field In Congenitally Deaf Cats., Blake E Butler, Nicole Chabot, Andrej Kral, Stephen G Lomber

Psychology Publications

Crossmodal plasticity takes place following sensory loss, such that areas that normally process the missing modality are reorganized to provide compensatory function in the remaining sensory systems. For example, congenitally deaf cats outperform normal hearing animals on localization of visual stimuli presented in the periphery, and this advantage has been shown to be mediated by the posterior auditory field (PAF). In order to determine the nature of the anatomical differences that underlie this phenomenon, we injected a retrograde tracer into PAF of congenitally deaf animals and quantified the thalamic and cortical projections to this field. The pattern of projections from …

Hippocampal Neurogenesis And Volume In Migrating And Wintering Semipalmated Sandpipers (Calidris Pusilla)., Nara Gyzely De Morais Magalhães, Cristovam Guerreiro Diniz, Daniel Guerreiro Diniz, Ediely Pereira Henrique, Patrick Douglas Corrêa Pereira, Isis Ananda Matos Moraes, Mauro André Damasceno De Melo, David Francis Sherry, Cristovam Wanderley Picanço Diniz

Brain and Mind Institute Researchers' Publications

Long distance migratory birds find their way by sensing and integrating information from a large number of cues in their environment. These cues are essential to navigate over thousands of kilometers and reach the same breeding, stopover, and wintering sites every year. The semipalmated sandpiper (Calidris pusilla) is a long-distance migrant that breeds in the arctic tundra of Canada and Alaska and winters on the northeast coast of South America. Its fall migration includes a 5,300-kilometer nonstop flight over the Atlantic Ocean. The avian hippocampus has been proposed to play a central role in the integration of multisensory spatial information …

Are There Place Cells In The Avian Hippocampus?, David F Sherry, Stephanie L Grella, Mélanie F Guigueno, David J White, Diano F Marrone

Brain and Mind Institute Researchers' Publications

Birds possess a hippocampus that serves many of the same spatial and mnemonic functions as the mammalian hippocampus but achieves these outcomes with a dramatically different neuroanatomical organization. The properties of spatially responsive neurons in birds and mammals are also different. Much of the contemporary interest in the role of the mammalian hippocampus in spatial representation dates to the discovery of place cells in the rat hippocampus. Since that time, cells that respond to head direction and cells that encode a grid-like representation of space have been described in the rat brain. Research with homing pigeons has discovered hippocampal cells, …

Religious Coping And Spiritual Struggle Among Emergency Room Patients With Suicidal Intent, Rosanna J. S. Bailey, Mark R. Mcminn, Mary A. Peterson, Kathleen Gathercoal

Faculty Publications - Doctor of Psychology (PsyD) Program

Previous literature has shown religion and spirituality to be protective factors for depressive symptoms and suicidal ideation, and that spiritual struggle is associated with increases in suicidal ideation. However, in some cases, positive religious coping may also be associated with risk factors for suicidality. The present study explored aspects of spiritual struggle or religious coping that were spontaneously offered and noted in a medical record during a standard emergency room risk assessment involving the Collaborative Assessment and Management of Suicidality (CAMS). Among 839 archival records from emergency department settings in Yamhill County, Oregon, in 2015 and 2016, only 36 interviews …

I Hate It, But I Can't Stop: The Romanticization Of Intimate Partner Abuse In Young Adult Retellings Of Wuthering Heights, Brianna R. Zgodinski

ETD Archive

In recent years, there has been a trend in young adult adaptations of Wuthering Heights to amend the plot so that Catherine Earnshaw chooses to have a romantic relationship with Heathcliff, when in Bronte’s novel she decides against it. In the following study, I trace the factors that contribute to Catherine’s rejection of Heathcliff as a romantic partner in the original text. Many critics have argued that her motives are primarily Machiavellian since she chooses a suitor with more wealth and familial connections than Heathcliff. These are indeed factors; however, by engaging with contemporary research on adolescent development, I show …

The Effect Of Computer-Delivered Brief Intervention On Heavy Alcohol Use: A Pilot Study, Benjamin Varner Laliberte

Wayne State University Dissertations

Alcohol misuse remains a significant issue on college campuses. One potential remedy, especially for those unwilling or unable to seek face-to-face intervention, are computer-delivered brief interventions. Although the literature is mixed regarding the magnitude of their effect on alcohol use, findings are consistent that they at least produce small changes in alcohol use. The current study tested a computer-delivered brief intervention (CDBI) against an education-only control in order to examine its efficacy in reducing alcohol use. Additionally, it tested the interactive effects of secondary psychopathic personality, a trait associated with higher rates of alcohol use. 100 heavy drinking college students …

Hearing Loss And Verbal Memory Assessment In Older Adults, Christina G. Wong

Wayne State University Dissertations

Prior research has found that adults with hearing loss perform worse on cognitive testing than adults without hearing loss, and some studies have suggested that hearing loss is associated with dementia. Heavy emphasis on tests involving auditory stimuli for memory assessment may result in overdiagnosis of cognitive impairment in individuals with hearing loss. The present study compared visual and auditory versions of a verbal memory test among older adults with and without hearing loss. Forty-one adults with moderate-to-severe, sensorineural hearing loss (HL) and 41 age-matched adults with normal hearing (NH) participated. Age ranged from 55 – 80 years. They completed …

Women’S Readiness To Engage In Risky Sexual Behavior: The Effects Of Interpersonal Violence Victimization And Social Rejection, Jacqueline Woerner

Wayne State University Dissertations

The current study explores the role of psychosocial factors in women’s likelihood to engage in risky sexual behavior (RSB). Social rejection is particularly relevant as it is linked to a wide range of negative outcomes including engagement in self-reported RSB; however, its causal role has been rarely studied in a systematic manner. Furthermore, interpersonal violence victimization has been associated with RSB, but the processes underlying this relationship are largely unknown. This study aimed to: 1) test the impact of social rejection on women’s tendency to engage in RSB; 2) understand victimization as an individual vulnerability for engaging in RSB; and …

Self, Death, And Suicide: Does An Animal Know Of These?, Carolyn A. Ristau

Animal Sentience

Peña-Guzmán makes a strong case, using examples from the media and scientific literature, that many captive animals suffer severely. In examining the possibility of animal suicide, he dismisses the need for “reflective self-subjectivity” and “intent” in suicidal behavior. He claims that at least some animals understand “death,” citing examples of behavior he deems to be death “rituals.” But these can be more simply interpreted. The possibility of animal suicide remains more dubious than Peña-Guzmán suggests.

Post-Training Inactivation Of The Anterior Thalamic Nuclei Impairs Spatial Performance On The Radial Arm Maze, R.E. Harvey, S.M. Thompson, L.M. Sanchez, Ryan M. Yoder, B.J. Clark

Psychology

The limbic thalamus, specifically the anterior thalamic nuclei (ATN), contains brain signals including that of head direction cells, which fire as a function of an animal's directional orientation in an environment. Recent work has suggested that this directional orientation information stemming from the ATN contributes to the generation of hippocampal and parahippocampal spatial representations, and may contribute to the establishment of unique spatial representations in radially oriented tasks such as the radial arm maze. While previous studies have shown that ATN lesions can impair spatial working memory performance in the radial maze, little work has been done to investigate spatial …

Changes In Behavior And Emotion Under Chicken Domestication, Martin Johnsson

Animal Sentience

Marino’s target article provides an overview of chickens’ cognition, emotion, and personality, with the aim of changing how people view chickens. In this commentary, I will agree that chickens deserve better than their reputation, but contend with a statement about the lack of behavioral change under chicken domestication.

Use Of Vertical Enclosure Space And Species-Typical Locomotion By A Rehabilitating Spider Monkey (Ateles Fusciceps), Jake Funkhouser

Undergraduate Honors Theses

With wild spider monkey populations in decline, investigations contributing to captive welfare, and successful rehabilitation and reintroduction knowledge is increasingly pressing. Quantifying and analyzing the appropriateness of naturalistic enclosure designs to foster species-typical behaviors is an effective way to address both of these needs. This study investigates enclosure space use, vertical space preference, substrate use, positional/postural modes, and interactions with human caregivers of a wild-caught, pet-trade rehabilitant Columbian black spider monkey (Ateles fusciceps rufiventris, N = 1). Video data collected daily from August to October 2015 via focal animal sampling (from 08:00 to 10:00) at Alouatta Sanctuary, Panama …

Civic Dignity And Meaningful Political Participation, Melissa Mahoney Smith

CGU Theses & Dissertations

This dissertation looks at how enhanced political participation opportunities can increase individual liberty and improve public-sector reform efforts. It blends political theory with contemporary concerns for individual well-being and government accountability. To do this, several research methodologies are used, including normative, qualitative process-tracing, and quantitative analysis.

First, the dissertation draws insights from ancient and modern political philosophy and the political thought and example of Jane Addams in 19th Century Chicago. It begins with Josiah Ober’s work on civic dignity, which he defines as “equal high standing” among citizens, marked by “non-infantilization and non-humiliation.” This definition is a useful starting point …

Ask Your Doctor About Exposure Therapy!: Direct-To-Consumer Marketing Of Empirically Supported Psychological Treatments For Anxiety, Joshua C. Fulwiler

Electronic Theses and Dissertations

Despite efforts to disseminate Evidence-Based Psychological Interventions (EBPIS) to mental health practitioners, most individuals with psychological disorders do not receive any form of treatment, and many others who do seek treatment do not receive EBPIS. The success of the pharmaceutical industry in effectively marketing prescription drugs directly to consumers is considered as a model for advancing dissemination of EBPIS. Utilizing undergraduate students as participants, the current study examined how potential consumers of mental health services respond to internet-based marketing information about EBPIS. Participants vieinformation about anxiety disorders and a specific type of treatment (i.e., cognitive-behavioral therapy) in both text and …
