Sex Differences In The Anatomy Of Mam E17 Treated Rats: A Developmental Model Of Schizophrenia, Cassandra Hartsgrove

Honors Program Theses and Projects

Enlarged ventricles and reduced cortical volume are neuroanatomical abnormalities correlated with schizophrenia and typically more severe in males. The MAM model of schizophrenia is a developmental disruption model that involves exposing animals to a teratogen, methylazoxymethanol acetate (MAM), to reflect the neuroanatomical traits of schizophrenia. Rodents exposed to MAM on embryonic day 17 (E17) experience a reduction of cortical volume and increased ventricular volume. Measuring brain weight and ventricular volume can be used to inversely measure the severity of cortical reduction. The circling method was used to measure the lateral ventricles of a sample of 27 rodents; 8 MAM-females, 7 …

Parental Genetic Contributions To Neonatal Temperament In A Nonhuman Primate (Macaca Mulatta) Model, Elizabeth K. Wood, Jacob N. Hunter, Joseph A. Olsen, Laura Almasay, Stephen G. Lindell, David Goldman, Christina S. Barr, Stephen J. Suomi, Daniel B. Kay, James Dee Higley

Faculty Publications

Temperament is an individual’s nature and is widely believed to have a heritable foundation. Few studies, however, have evaluated paternal and maternal contributions to the triadic dimensions of temperament. Rhesus monkeys are widely utilized to model genetic contributions to human development due to their close genetic-relatedness and common temperament structure, providing a powerful translational model for investigating paternal and maternal genetic influences on temperament. The temperament of rhesus monkey infants born to 19 different sires and 50 different dams was assessed during the first month of life by comparing the temperament of paternal or maternal half-siblings reared with their mothers …

Teacher Perception Of A Brief Mindfulness-Based Curriculum And Its Impact On The Development Of Social Skills And Self-Regulation On A Preschool Classroom, Allison Poggendorf

Educational Specialist, 2020-current

Recent studies on mindfulness and its impact on children have found promising results, especially with social-emotional skill development. A majority of the research on mindfulness applied in educational setting tends to focus on elementary and high school students, and there is limited, but growing research that examines the impact of mindfulness among early childhood students. This current study explored the impact of a brief mindfulness-based curriculum on an intact preschool classroom. Specifically, this study examined if preschool teachers perceive mindfulness practices in the classroom to impact their students’ self-regulation skills and social skills and how likely they were to continue …

'Bleeding-In-The-World': A Qualitative Study Of Self-Cutting And Blood, Sadie Mohler

Electronic Theses and Dissertations

This dissertation is an existential, phenomenological study of the role and meaning of blood in self-cutting. Using in-depth, open-ended interviews with participants who self-cut, the author gathered data on the multisensorial experience of blood and bleeding in self-cutting. Data analysis was organized around the lifeworld existentials of corporeality, temporality, spatiality, communication, and relationality. The impact of blood and bleeding across each lifeworld dimension emphasized highly relevant, and previously unstudied, aspects of the lived experience of self-cutting. The six themes identified and explored are (a) blood as an animate abject; (b) bleeding and control; (c) bleeding is a process and the …

Calm-Mo: An Integrative Tool For Psychological Mindfulness, Charles L. Miller

Dissertations, 2020-current

Henriques has developed a “Unified Theory” that consists of eight key ideas he argues can effectively frame both the science of psychology and the practice of psychotherapy. CALM-MO, the eighth of these ideas, offers an integrative, principled approach to psychological mindfulness. CALM-MO is an acronym that encapsulates the process of cultivating a “calm” meta-cognitive observer that embodies the attitudes of curiosity, acceptance, loving compassion, and motivation toward valued states of being. Henriques posits that the idea consolidates key elements from across the various schools of thought to bring together essential therapeutic principles geared toward seeking and maintaining well-being. As such, …

An Evaluation Of Ethograms Measuring Distinct Features Of Enrichment Use By Captive Chimpanzees (Pan Troglodytes), Julia L. Greeson, Kara I. Gabriel, John B. Mulcahy, Bonnie King Hendrickson, Susan D. Lonborg, Jay C. Holloway

Student Published Works

Environmental enrichment provides mental stimulation and minimizes abnormal behaviors in captive animals. In captive chimpanzees, individual animals may vary in the ways in which they benefit from enrichment or use enrichment devices, so investigating nuances in enrichment use may improve the welfare of captive chimpanzees. In the current study, three ethograms measuring distinct features of enrichment use (i.e., enrichment object, manipulation behavior, and social context) were evaluated by coding videos of captive chimpanzees (Pan troglodytes) at Chimpanzee Sanctuary Northwest in Cle Elum, WA. A total of 732 min and 58 s of video footage was coded from a larger video …

Impact Of Parental Substance Misuse On Attachment In Young Adults: A Qualitative Approach, Susan E. Hardman

Dissertations, 2020-current

This study examined the impact of parental substance misuse on young adult development and relationships by interviewing young adults about their experience being raised by a parent who misused substances. A qualitative design based on constructivist grounded theory and informed by constructs from attachment theory was used. Participants consisted of 10 young adults, ages 18-26, who endorsed being raised by a parent who misused substances. The interview questions developed for the study were informed by a measure of adult attachment. Analysis of the data included identification of emergent categories/themes as well as a priori constructs from attachment theory (safe haven, …

The Acceptability And Feasibility Of Virtual Parent Acceptance And Commitment Therapy Groups: A Feasibility Study, Abigail Elizabeth Moretti

Theses and Dissertations

Parents of children with autism spectrum disorder (ASD) experience higher rates of anxiety, depression, and poor overall well-being, particularly when their child also engages in challenging behavior (e.g., self-injury, aggression, property destruction). Acceptance and commitment therapy (ACT), which encourages psychological flexibility and attending to the present moment, is particularly suited for this population because parents of children with ASD experience high stress levels and difficulty with adaptive coping. The aim of the current study is to examine the feasibility and acceptability of implementing virtual ACT groups with parents of children with ASD and co-occurring challenging behavior. Participants attended an in-person …

The Combined Benefits Of Dispositional Mindfulness And Trait Self-Compassion As Potential Buffers Of The Effects Of Perceived Stress On Sleep Quality In College-Aged Young Adults., Jackie Ma

Electronic Theses and Dissertations

Using a nonclinical sample of 108 undergraduates between the ages of 18 to 25 years old, this cross-sectional study investigated the relationship between dispositional mindfulness (as measured by the Five Facet Mindfulness Questionnaire; Baer et al., 2006) and sleep quality (as measured by the Pittsburgh Sleep Quality Index; Buysse et al., 1989). Second, it evaluated the association between trait self-compassion (as measured by the Self-Compassion Scale; Neff, 2003b) and sleep quality. Third, it aimed to test for an interaction effect between dispositional mindfulness and trait self-compassion as buffers against the adverse effects of perceived stress on sleep quality. Results showed …

Compliance With Ostracism: How Excluding A Member Of A Despised Outgroup Affects Psychological Need Satisfaction, Emma Nettles

USC Aiken Psychology Theses

Ostracism is a social process through which individuals are excluded or ignored (Williams, 1998). While recent research has slowly shifted toward the perpetrators of ostracism, relative to the targets, there is still little research on the effects of complying with ostracism. While previous research suggests engaging in ostracism leads to negative affect and thwarted need satisfaction, ostracism was directed toward an otherwise underserving target (Legate et al., 2013). The current research examined the effects of being instructed to ostracize a member of a despised outgroup on affect and need satisfaction. Seventy-one participants were recruited to play Cyberball, in which they …

Examining Dehumanization Of Individuals With Schizophrenia, Brianna Drake

USC Aiken Psychology Theses

Objective: Previous literature examines dehumanization of marginalized groups; though, most of this work focuses on ethnic and racial groups. Currently, there is a gap in the literature examining the extent to which people with mental illness are dehumanized. This study examined whether people with schizophrenia are dehumanized (relative to other marginalized groups, such as drug addicts). Furthermore, this research will investigate if using “person-first” language can attenuate dehumanization.

Method: Participants (n = 310) were recruited from Amazon Mechanical Turk to complete a measure of dehumanization and demeaning needs for each of the nine targets (i.e., self, close friend, lawyer, elderly, …

Examining The Impact Of Attachment And Parent Socialization Of Emotion In Childhood On Emotion Regulation In Maltreated Adults, Nikki Major

USC Aiken Psychology Theses

Objectives: The aim of the current study was to examine the relationship between child maltreatment and adult emotion regulation by examining parenting processes of emotion socialization and attachment security as possible mechanisms accounting for this relationship. It was hypothesized that maltreated adults would retrospectively report more unsupportive responses from parents/caregivers, greater attachment insecurity, more difficulty with emotion regulation, and using expressive suppression more than cognitive reappraisal. It was also hypothesized that unsupportive responses to emotions and attachment security would both indirectly effect the relationship between child maltreatment and adult emotion dysregulation.

Method: A sample of 226 participants from Amazon Mechanical …

Prevalence And Predictors Of Polypharmacy In Adolescents Who Have Engaged In Sexually Abusive Behaviors, Rebecca Gilley

Electronic Theses and Dissertations

Polypharmacy, or the concurrent use of multiple medications, is associated with detrimental outcomes for patients and has gathered increasing attention within the scientific clinical literature. Pediatric populations warrant special consideration for the practice of polypharmacy, as medication effects are more pronounced in youth and adverse effects may have a lasting impact on development. This dissertation study examined psychotropic prescribing practices in a sample of adolescents who have engaged in sexually abusive behaviors, a subset of justice-involved youth who are at risk for polypharmacy. General prescribing trends were examined, and a principle components analysis involving variables associated with risk of polypharmacy …

Measuring Affective Responses To Different Types Of Nature Exposure, Abigail P. Moffett

All NMU Master's Theses

Natural environments provide many physical and physiological benefits for an individual. Examples may include decreased stress levels, increased intrinsic motivations and prosocial behavior, and more. Fueled by the curiosity of the extent to which nature provides these benefits, this study investigated whether pre-existing preference for either waterscape scenes or mountainous scenes, as well as self-reported affective and associative responses to those environmental exposures are possible explanations for the experience of wellbeing when one is exposed to nature. Measures included the Nature Relatedness Scale, State Vitality Scale, Positive and Negative Affect Scale, and a nature preference scale (mountainous vs. waterscape). Nature …

Crime Scene Behaviors Of Sexual Murderers With And Without A Criminal History Of Sexual Assault, Tirza Z. Ben Ari

Student Theses

This exploratory study is intended to serve as a gateway to future research about the differences between sexual murderers with (HSAO) and without (N-HSAO) a recorded criminal history of sexual assault, on which there is little to no comparative literature. This study aims to extend our understanding of these groups by comparing their crime scene (and crime-related) behaviors and exploring their underlying psychological functioning. The results suggest that N-HSAO have a significantly higher tendency to murder friends or strangers, initially attack or abduct their victims from the victim’s residence, use more than one killing method in the murder, attack their …

A Small Wolf Eats A Large Apple: An Experimental Investigation Of The Temporal Processing Of Conceptual Magnitudes, Carolina Alvarez

Theses and Dissertations

When individuals are presented with two options and are asked to select the conceptually larger item, a size congruity effect is usually observed. A size congruity effect is present in comparison tasks when congruent stimuli, whose physical size and conceptual size match, are compared much faster than incongruent stimuli, whose physical size and conceptual size do not match. The current study used images and words as stimuli to investigate the two competing hypotheses for the size congruity effect using delta plots. Positive delta plots were observed when response time for incongruent items was compared to congruent items, providing evidence of …

The Influence Of Motivation, Role Identity, And Perceived Meaningfulness Of Work On The Relationship Between Volunteer Satisfaction And Volunteer Contribution, Tonia Christine Caraveo

Electronic Theses, Projects, and Dissertations

Volunteering, the act of donating time and effort to contribute to society is a unique form of helping that includes deliberate non-obligated services given one time or long-term. Utilizing an integrated approach incorporating the functionalist perspective and role identity theory as framework, the present study re-examined factors that influence volunteer contribution. The sample consisted of 161 participants who have donated time volunteering. Structural equation modeling (SEM) was used to test the model. Results of the structural equation model indicated the hypothesized model was not a good fit. As such, no significance was found among the expected relationships between volunteer satisfaction, …

Look, But Don’T Touch: Impact Of Covid-19 On The Nicu Caregiver, Rebecca C. Otwell-Dove

Electronic Theses and Dissertations

Admission of an infant into the neonatal intensive care unit (NICU) is an experience that has been associated with a variety of both positive and negative health outcomes for parent and child. While both the setting name and the admitted population alludes to a sole focus on the affected infant, what often remains underrecognized is the impact on the ones who care for the newborn long before and longer after their NICU stay. Given the recency and unprecedented impact of the COVID-19 pandemic, very little research has examined the impact of COVID-19-specific stress on the experience of parents of infants …

Emotional Support Animal Partnerships: A Multimethod Investigation, Jillian Ferrell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Emotional Support Animals (ESAs) are increasing in prevalence and awareness, though not all the publicity and attention have been positive. Many people, including housing officials, persons with disabilities, health professionals, and the general public are confused about the roles and rights of ESAs. Misunderstandings, lack of awareness, and fraud have led to dangerous and inappropriate situations for humans and animals alike despite overwhelming evidence of powerful therapeutic benefits of the human animal bond.

Three studies provide insight into various perspectives involved in ESA partnership experiences and development. Each study provides a theoretical, quantitative, and qualitative approach, respectively, to explore the …

Music: Seeking Pleasure, Emotional Language, Ritualized Communication, Jillian N. Gerlach

Interdivisional Studies Summer Fellows

The impetus for my project was how I view listening to music as a spiritual or religious experience. Listening to music, instead of practicing religion, satisfies my inclination toward spirituality. In the introduction to my paper, I outlined how music exists in my life. I thought it was valuable to provide my unique experience to give context to my research. I created a diagram that delineates how I interact with music and the benefits I derive from listening to music. During this self-reflection, I realized listening to music functions like a ritual for me. I noticed my individual ritualized listening …

The Role Of Nest Location On The Reproductive Success Of Piping Plovers Breeding At Rockaway Beach, New York, Clara I.D. Arndtsen

Theses and Dissertations

The study’s goal was to learn what aspects of the piping plover experience affect reproductive outcomes at Rockaway Beach Endangered Species Nesting Area. Nest location was found to help predict reproductive success. Nests further from American oystercatcher nests were likely to fledge more chicks. Reproductive success was low in 2021.

Gaze In Cats And Dogs, Michael Bogese

Theses and Dissertations

Domestic dogs (Canis lupus familiaris) developed many behaviors across domestication, one example being gaze behavior. Gaze is the crux of other behaviors that make dogs unique in human-animal dyads, including lookbacks, gaze-following, and participation in an oxytocin feedback loop. Gaze behavior may have been motivated and sustained by evergreen cooperative relationships between dogs and humans (e.g., hunting, service roles). One way to confirm this relationship is to compare dogs to a domesticated species that lacks a protracted history of companionship: the domestic cat (Felis catus). In this study, we compare the gaze duration to owners of …

The Role Of Parental Health And Distress In Assessing Children’S Health Status, Sherrie H. Kaplan, Marilou Shaughnessy, Michelle A. Fortier, Marla Vivero‑Montemayor, Sergio Gago Masague, Dylan Hayes, Hal Stern, Maozhu Dai, Lauren Heim, Zeev Kain

Department of Psychology: Faculty Publications

Purpose The purpose of the study was to examine the contributions of parents’ health and distress to parent’s and children’s assessments of children’s health.

Methods We used baseline data from a longitudinal study of 364 children (ages 4–12) about to undergo surgery and their parents in a Southern California pediatric hospital. We used the 20-item child self-reported CHRIS 2.0 general health and the parallel parent-reported measure of the child’s health, along with a measure of parental distress about the child’s health were administered in the perioperative period. Other measures included parents’ physical and mental health, quality of life, distress over …

The Abstract Language: Symbolic Cogniton And Its Relationship To Embodiment, Steven A. Lenarduzzi

ETD Archive

Embodied theories presume that concepts are modality specific while symbolic theories suggest that all modalities for a given concept are integrated. Symbolic and embodied theories do fairly well with explaining and describing concrete concepts. Specifically, embodied theories seem well suited to describing the actual content of a concept while symbolic theories provide insight into how concepts operate. Conversely, neither symbolic nor embodied theories have been fully sufficient when attempting to describe and explain abstract concepts. Several pluralistic accounts have been put forth to describe how the semantic/lexical system interacts with the conceptual system. In this respect, they attempt to “embody” …

Cortisol Administration Normalizes Aberrant Functional Connectivity In Women With Depression, Adam C. Runyan

Dissertations

Previous resting-state functional connectivity (rsFC) research has identified aberrant connectivity in several large brain networks in depression, including the default mode (DMN), frontoparietal (FPN), and salience networks (SN). Connectivity of these networks is also related to depressive symptom severity and is affected by cortisol levels. To our knowledge, this is the first study to investigate the effects of acute cortisol administration on rsFC of DMN, FPN, and SN in individuals varying in depression history and severity. We collected resting-state fMRI scans for 74 women with and without a history of depressive disorder after administration of cortisol and placebo using a …

The Lived Experience Of Postpartum Anxiety During Covid-19: A Hermeneutic Phenomenological Study, Walker Ladd Phd, Jenny De Decker

The Qualitative Report

The experience of pregnancy and postpartum anxiety disorders results in adverse birth outcomes and the disrupted development of infants and children. Since the COVID-19 Pandemic, the Centers for Disease Control and Prevention (CDC) has designated pregnant and postpartum women as more vulnerable to COVID-19 (CDC, 2021), and perinatal mood and anxiety disorders rates have increased. However, research regarding the lived experience of women with postpartum anxiety (PPA) during a global pandemic remains lacking. Using van Manen’s hermeneutic phenomenological research method, we interviewed eight women self-identifying as having had PPA during the COVID-19 pandemic. Analysis revealed five themes describing the lived …

The Relationship Between Family Environment And Specific Phobias, Jerrica Renee Guidry

LSU Doctoral Dissertations

Specific phobias are the most prevalent disorder among adults and highly common among children. Additionally, specific phobias diagnosed in childhood has been associated other serious mental illnesses later in life (de Vrie et al., 2019). Research pertaining to parenting factors associated with anxiety disorders has been extensive, including parental psychopathology, parent-child relationships, parental control, and parental stress. However, less emphasis has been placed on familial factors which may contribute to the development and maintenance of specific phobias. According to the limited literature focusing on the family factors associated with specific phobias, parent psychopathology and parent over-control are important factors. Multiple …

The Effects Of Overshadowing In Drosophila Melanogaster With Experimentally Evolved Preference, Jill Lee

Theses

As seen in decades of psychology research, preferences play a major role in driving the decision-making process in both humans and animals. Researchers have advocated for using the technique of experimental evolution as a way to address some of the foundational questions on preferences. These preferences can also affect what is later learned and how well new experiences are learned. Salience is usually mentioned as an important component of what could influence preferences. Animals such as Drosophila melanogaster, that lay eggs without any additional maternal or paternal care, it is important to be selective when deciding where to lay …

Food Insecurity In An Anthropogenic Age: An Analysis Into How Consumer Demand Will Shift During Crisis Events, Chloe G. Parsons, Christina Kuchmaner

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

Consumers in the United States may need to adjust their food demand due to food insecurity caused by climate warming events. Research has focused on how climate change impacts food supply chains and distribution; however, there was little research on how consumers responded to these changes. This study analyzed how consumers across the United States responded to food insecurity caused by crisis events (i.e. pandemics and climate change), how consumers shifted from grocery store vendors to local food vendors, and if migration or food miles may increase based on potential food shortages. One study was initiated through survey and a …

Mothers’ Reflections On Cat Ownership For A Child With Autism Spectrum Disorder During Covid-19, Saskia Keville, Sophia De Vita, Amanda K. Ludlow

People and Animals: The International Journal of Research and Practice

Animal- assisted interventions are increasingly used as a complementary therapy in clinical practice to support people with autism spectrum disorder (ASD), with promising outcomes compared to traditional therapies. Less is understood about the therapeutic benefits of more accessible and affordable small pet ownership for families with a child with ASD, alongside the pets’ welfare living in these homes. This study explored the experiences of cat ownership for young people with ASD from the perspective of their mothers during a time of transition generated by COVID-19. Semi-structured interviews were conducted with six mothers and transcripts analyzed using reflexive thematic analysis. Three …
