Foster Parents' Perceptions And Beliefs About Social Emotional Development In Infants And Toddlers, Susan R. Noel

DNP Projects

Infants and toddlers placed in foster care are at increased risk for social-emotional (SE) development dysregulation. Foster parents, as surrogate parents, play a critical role in a young child having the potential for healthy SE development. The transactional model supports the complex and intricate interplays and transactions of the child, the foster parent, and the environment that influences a healthy SE development. This qualitative descriptive study explored foster parent knowledge, behavioral cue recognitions, and role perception regarding a young child's SE development. Although the sample size was small, the study provides relevant information, from the on-going experiences of foster parents, …

Do Olfactory Stimuli Increase Presence During Exposure Tasks: A Comparative Study, Benson Munyan

Electronic Theses and Dissertations

Exposure therapy (ET) is an extensively studied and supported treatment for anxiety and trauma-related disorders. ET works by exposing the patient to the feared object or situation without any danger in order to overcome the related anxiety. Over the past few years, various technologies including head-mounted displays (HMDs), scent machines, and headphones have been used to augment the exposure therapy process by presenting multi-sensory cues (e.g., sights, smells, sounds) to increase the patient*s sense of presence. While studies have shown that scents can elicit emotionally charged memories, no prior research could be identified that examined the effect of olfactory stimuli …

The Effect Of Traumatic Brain Injury On Exposure Therapy In Veterans With Combat-Related Posttraumatic Stress Disorder, Kathleen Ragsdale

Electronic Theses and Dissertations

Veterans of Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn are presenting for treatment with high rates of combat-related posttraumatic stress disorder (PTSD) and traumatic brain injury (TBI), spurring a need for clinical research on optimal treatment strategies. While exposure therapy has long been supported as an efficacious treatment for combat-related PTSD, some clinicians are hesitant to utilize this treatment for veterans with TBI history due to presumed cognitive deficits that may preclude successful engagement. The purpose of this study was to compare exposure therapy process variables in veterans with PTSD only and veterans with PTSD+TBI. Results suggest …

Association Between Toxocariasis And Cognitive Function In Young To Middle-Aged Adults, Bruce L. Brown, Lance D. Erickson, Shawn D. Gale, Andrew Berrett, Dawson W. Hedges

Faculty Publications

The ascarid nematodes Toxocara canis (Werner, 1782) and Toxocara cati (Schrank, 1788) may infect humans resulting in toxocariasis. A prior study associated species of Toxocara Stiles, 1905 with cognitive deficits in children. To determine if a similar association between toxocariasis and cognition exists in adults, we analysed a large dataset from the United States’ Center for Disease Control’s National Health and Nutrition Examination Survey. We used linear-regression and multivariate models to examine the association between toxocariasis as assessed by the presence of anti-Toxocara IgG antibodies and three measures of cognitive function – simple reaction time (SRT), symbol-digit substitution (SDS) and …

Resiliency Of Multiple-Placed Foster Youth Experiencing Emotional Competence: A Mixed-Methods Study, Audrey Murph-Brown

Theses and Dissertations

This applied dissertation was designed to address the resilient processes of multiple placed foster youth to develop age-appropriate emotional competence. Adding texture to the study was the role played by race and culture. Inherent to the study were the voices of successful multiple-placed foster youth. The research attempted to respond to gaps in the literature regarding African American and Hispanic youth placed in foster placements that, if better understood, can positively impact the livelihoods of other multiple-placed foster youth. The minor participants, 10 to 17 years old, selected for this study were no longer wards of the state, having been …

A Comparison Of Mitragyna Speciosa And Mitragynine Against Opioids On Thermal Nociception In Rats, Catherine Criddle

Honors Theses

The purpose of this experiment is to compare Mitragyna speciosa (M. speciosa) and its active component, mitragynine, a known µ-opioid receptor (MOR) agonist, against well-known and commonly abused opioids, morphine and oxycodone. Another goal of this research is to determine if these compounds are also active when administered orally as is typical in human users. Male Sprague-Dawley rats were administered M. speciosa and mitragynine both intraperitoneally (IP) and orally and their antinociceptive effects were evaluated on the hotplate. Mitragynine exhibited antinociceptive effects similar to oxycodone when administered both IP and orally. M. speciosa exhibited a trend towards antinociceptive effects when …

Cortisol Levels And Voltage Conditions Of College Students, Adriana Steffens

Walden Dissertations and Doctoral Studies

There is a limited research base on low voltage brain conditions, which are characterized by electrical activity being measured at below 20 microvolts. The purpose of this study was to examine the relationship between saliva cortisol levels and voltage using an EGG in a college student population. Illuminating this relationship is important to inform how low voltage conditions can affect daily memory and cognitive functioning of undergraduate college students that may be a result of stress. The college student population may be vulnerable to the low voltage condition because of stress from the transition between teenage and adult life and …

Editorial: Neural Implementation Of Expertise, Merim Bilalic, Robert Langner, Guillermo J. Campitelli, Luca Turella, Wolfgang Grodd

Research outputs 2014 to 2021

How the brain enables humans to reach an outstanding level of performance typical of expertise is of great interest to cognitive neuroscience, as demonstrated by the number and diversity of the articles in this Research Topic (RT). The RT presents a collection of 23 articles written by 80 authors on traditional expertise topics such as sport, board games, and music, but also on the expertise aspects of everyday skills, such as language and the perception of faces and objects. Just as the topics in the RT are diverse, so are the neuroimaging techniques employed and the article formats. Here we …

Secure-Base Caregiving And Adult Attachment Development Within The Client-Psychotherapist Relationship, Dennis A. Weeks

Walden Dissertations and Doctoral Studies

Recent studies have shown significant improvements in the attachment security of adult therapy clients during therapy, supporting Bowlby's theory that such improvement can be influenced by secure-base caregiving provided by mentors such as therapists. However, because these studies did not measure the secure-base variable, its relationship to client attachment development remains unknown. The present study is the first to evaluate that relationship by measuring clients' pre and posttherapy attachment security using the Relationship Scales Questionnaire and therapists' secure-base caregiving using the Client Attachment to Therapist and Working Alliance Inventory, Short Form. Of 21 initially insecure client participants, 17 experienced high …

Differences In Stress Biomarkers In Women With High And Low Stress Appraisal, Clarissa Sara Gomez

Open Access Theses & Dissertations

Measures of physiological biomarkers have been widely used in the field of stress research to explain how stress negatively impacts health outcomes. Women in particular have been shown to be more at risk for developing physiological and psychological stress-induced conditions (e.g., hypertension, depression) due to hormonal differences (Kirschbaum et al., 1992), but more importantly, because of their appraisal of stressful events (Schamus et al., 2008). Few studies however have examined whether womenâ??s stress appraisal is predictive of stress reactivity, as measured by stress biomarkers, during stressful events. The goal of this study was to examine whether stress appraisal predicted stress …

Child-Centered Play Therapy For Children With Autism: A Case Study, Ashley H. Morgenthal

Antioch University Dissertations & Theses

This dissertation evaluated archival data from the implementation of a child-centered approach to play therapy with a young girl diagnosed with autism. Goals of treatment included promoting spontaneous symbolic play and increasing verbal communication skills. Young children with autism who engage in early intervention often receive behavioral interventions, such as applied behavior analysis (ABA), on a regular basis. However, the use of child-centered play therapy as an intervention is not as common, as play is frequently viewed as being a deficiency for children with autism. In psychological theory, play is often regarded as a child’s work, and his or her …

Effects Of Presenting Normative Alcohol Data On Perceptions Of College Drinking Behavior, Cullen Patrick Hardy

Antioch University Dissertations & Theses

Alcohol abuse, often in the form of binge drinking, is a problem that every college campus faces. Many researchers suggest that students believe that their peers drink more alcohol than is actually true, and use such a perception as a justification to drink more alcohol than should be consumed (Perkins, Haines, & Rice, 2005). The purpose of this study is to understand whether presenting normative information on drinking behavior among college students in two different ways (focus on heavy drinking or focus on abstinence) has an effect on the perceptions of drinking behavior.

The Experience Of Sibling Death In Childhood: A Qualitative Analysis Of Memoirs, Katrin Neubacher

Antioch University Dissertations & Theses

This qualitative study explored the experience of the death of a sibling in childhood. Seven memoirs written by individuals who lost a sibling in childhood were analyzed using Interpretive Phenomenological Analysis. Themes focused on the child’s lived experience of sibling loss, parental and familial function, and factors identified as supporting the child’s grieving and functioning. Where relevant, an in-depth review of the existing literature of relevant psychological research and theories supported and expanded on the themes identified in the narratives. As the purpose of this research was to inform a model for understanding the life and grief of a bereaved …

The Impact Of Baby Sign Training On Stress Levels Of Daycare Providers, Grisel Julieta Rodriguez

Open Access Theses & Dissertations

Proponents of baby sign claim improvements in child-caregiver interactions and reductions in parental stress as benefits of implementing baby sign. Due to research contradicting the claims, and to the rise in daycare attendance, the current study investigated the effects of a baby sign workshop on the stress perception of daycare providers. A pre-test post-test between groups design with 20 participants was conducted using the Perceived Stress Scale (PSS10) and a workshop-specific descriptive survey as measures. The difference between the post-test stress levels of experimental and control groups approached significance, as did the differences between pre-test and post-test results for the …

Cocaine-Induced Behavioral Sensitization And Conditioned Place Preference In Japanese Quail (Coturnix Japonica): A Focus On Sex Differences And Dopaminergic Mechanisms, Karin E. Gill

Theses and Dissertations--Psychology

Research has indicated that gonadal hormones may mediate behavioral and biological responses to cocaine. Estrogen, in particular, has been shown to increase behavioral responding to cocaine in female rats relative to male rats. The use of Japanese quail may add to our knowledge of sex differences in drug abuse because of their advanced visual system and the ability to control their gonadal hormones via alterations in photoperiod. In three experiments, cocaine-induced behaviors were examined using this avian model.

In Experiment 1, I investigated the potential sex differences in cocaine-induced locomotor activity between male and female Japanese quail and I examined …

Delicious Justice: Schadenfreude Toward Atheists Bound For Hell, Maxine Najle

Theses and Dissertations--Psychology

In the wake of the death of a prominent atheist figure in 2011, an especially unsavory side of anti-atheist prejudice became evident as many celebrated the death of a prominent atheist, rejoicing that he would be in hell. The current study explores how these attitudes reveal a sense of schadenfreude in anti-atheist prejudice previously unexplored in the literature. Potential origins of this schadenfreude are discussed, and a study to experimentally explore this phenomenon was carried out. Using the repeated taste-test paradigm, this study gave participants atheist primes and hell primes between identical drinks and measure perceived taste after these manipulations, …

Development Of An Avian Model For Identifying Individual Differences In Drug Vulnerability, Beth A. Rice

Theses and Dissertations--Psychology

The attribution of incentive salience to cues that become associated with drugs of abuse is a critical characteristic of individuals who may be vulnerable to drug addiction. Rodents with the propensity to sign track are thought to be vulnerable to drug abuse. The goal of the current work was to investigate whether sign trackers (STs) would acquire cocaine conditioned place preference (CPP) to a discrete cue using an avian species. In Experiment 1, sign and goal trackers (GTs) were first identified using a one third rank order split. Following identification, cocaine-CPP was conducted with a discrete cue in each end …

Effect Of Social Peers On Risky Decision Making In Male Sprague Dawley Rats, Virginia Weiss

Theses and Dissertations--Psychology

Adolescence is a time associated with increased risk taking and peer relations. Research has shown that adolescents are more vulnerable to peer pressure compared to adults, leading to exacerbated risk taking. Preclinical research suggests that these findings may also be applicable to adolescent rodents, which find social interaction rewarding and are prone to risky behavior. There is, however, little research on the effect of social interaction on rodent models of risky decision-making. This thesis utilized social chambers, which consisted of adjacent operant chambers separated by wire mesh. Adolescent rats performed a risky decision-making task in which they had a choice …

On A(Pe)Theism: Religious Dehumanization Of Atheists And Other Outgroups, Ben Kok Leong Ng

Theses and Dissertations--Psychology

Research on the dark side of religion has recently found evidence that anti-atheist prejudice is embedded in distrust (Gervais et al, 2011). Anti-atheist prejudice though old in its form, has only been systemically researched on over the last couple of years. This study seeks to extend on research in anti-atheist prejudice by examining religious dehumanization of atheists in comparison with other religious outgroups – gays and Muslims. Study 1 utilized a two factor model of dehumanization (Haslam, 2006) to examine dehumanization. Study 2 serves as a conceptual replication and extension using two different measures of dehumanization. Study 1 failed to …

The Effects Of Alcohol And Hypoxia Exposure In The Developing Brain, Megan L. Carter

Theses and Dissertations--Psychology

Exposure to alcohol (ethanol (ETOH)) during fetal development results in a variety of cognitive/behavioral deficits. The effects of fetal ETOH exposure vary across individuals and numerous studies have shown that ETOH’s interaction with other variables can affect outcome in offspring. These studies investigated the effects of developmental ETOH and hypoxia. It was hypothesized that a history of ETOH during development alters the response to a subsequent hypoxic challenge, such as that which may occur during parturition; this results in central nervous system (CNS) damage and behavioral deficits.

The first study determined if developmental ETOH and hypoxia exposure produced behavioral deficits …

Emergent Literacy Skills In Print And Electronic Contexts: The Influence Of Book Type, Narration Style, And Attention, Kathryn Joyce O'Toole

Dissertations

Preschoolers can learn words and story content from traditional print books, but there has been no direct comparison of their learning from print and e-books while controlling for narration style. Additionally, very little empirical work has utilized a tablet e-book as the majority of research has examined learning from computer e-books. The current project examined how 4-year-olds (N = 100) learned words and story content from four different book reading contexts: a print book read aloud by a live adult, a print book narrated by an audio device, a tablet e-book read aloud by a live adult, or a tablet …

Exploring The Interactive Effects Of Social Learning Theory And Psychopathy On Serious Juvenile Delinquency, Brandy Barenna Henderson

USF Tampa Graduate Theses and Dissertations

Social learning theory continues to be one of the most enduring theories of crime. Psychological criminology, on the other hand, tends to explain crime in terms of behavioral propensities. This research is specifically focused on the generality of social learning theory as it varies across a measure of criminal propensity- in this case, psychopathy. Prior studies have tested various theories with the use of measures of propensity, but the theory is rarely social learning, and the measure of propensity has never been psychopathy. The current study examines three components of social learning theory (definitions, differential association, and differential reinforcement) to …

Neural Correlates Of Inhibitory Function Following The Implicit Processing Of Emotional Faces, Lorri A. Kais

Master's Theses

Emotion and cognitive function interact to play a central role in determining

human thought and behavior. Attention to emotion can facilitate or hinder cognitive

control efforts based on the given contextual demands of the task at hand. This study used

scalp electroencephalography (EEG) methods to examine the link between valence of

facial stimuli and neural changes associated with emotional face processing and

subsequent inhibitory response. 20 participants completed a gender discrimination stop-

signal task using emotional faces. Facial valence did not differentially modulate the P200

event-related potential (ERP), indicating that happy and sad faces recruit similar neural

resources in the …

Fear Conditioning And Extinction In Childhood Obsessive-Compulsive Disorder, Joseph F. Mcguire

USF Tampa Graduate Theses and Dissertations

Fear conditioning and extinction are central in the cognitive behavioral model of obsessive-compulsive disorder (OCD), which underlies exposure-based cognitive behavioral therapy (CBT). Youth with OCD may have impairments in conditioning and extinction that carries treatment implications. The present study examined these processes using a differential conditioning paradigm. Forty-one youth (19 OCD, 22 community controls) and their parents completed a battery of clinical interviews, rating scales, and a differential conditioning task. Skin conductance response (SCR) served as the primary dependent measure across all three phases of the conditioning procedure (habituation, acquisition, and extinction). During habituation, no meaningful differences were observed between …

Therapeutic Horseback Riding With Military Veterans: Perspectives Of Riders, Instructors, And Volunteers, Leslie Lafleur

Antioch University Dissertations & Theses

Statistics reveal that over 353,000 military members have been diagnosed with PTSD and/or TBI resulting from war-related activities. With the rising number of war stress injuries, there have not been enough psychotherapeutic services to meet the current demand for the care of returning veterans from Iraq and Afghanistan. Although some intervention strategies have been deemed successful, the current standards of care (e.g., exposure therapy, cognitive therapy) are limited by training inadequacies, accessibility, and outcomes (e.g., retention, early drop out, resistance, non-responsiveness). Furthermore, it is unclear whether these treatments are efficacious in addressing the unique symptom presentations of this population. The …

The Effect Of Emotion On Associative And Item Memory, Priyanga Jeyarathnarajah

Theses and Dissertations (Comprehensive)

Numerous studies to date have demonstrated superior memory for emotional compared to neutral stimuli (Kensinger & Corkin, 2004; Bennion et al., 2013). This finding, although relatively stable across the item memory literature, becomes less consistent when examined in tasks measuring memory for associative or source information (Chiu et al., 2013). For this reason, the present study set out to examine how emotional content (negative, positive and neutral word pairs) influences memory in two distinct associative and item recognition tasks: associative identification (AI), associative reinstatement (AR), paired-item recognition, and single-item recognition. In measuring the influence of emotion on associations using an …

The Role Of Heart Rate Variability In The Treatment Of Migraines, Thomas M. Ledoux

Antioch University Dissertations & Theses

This dissertation assessed the role of heart rate variability (HRV) in the treatment of migraine headaches. The extent of this relationship was measured through a 12-session HRV biofeedback protocol to increase HRV and decrease migraine frequency through resonance frequency breathing (RFB) training. This project used a single-case design methodology to analyze phase changes in physiological variables with a specific focus on changes in HRV and migraine symptoms from baseline to completion of the biofeedback protocol. The prevalence of migraine headaches is discussed, the history of biofeedback as an intervention for migraine is reviewed, and the rationale for the relationship between …

Behavioral Adjustment In Children With Life Threatening Illness A Qualitative Study, E. Joseph Becher Jr.

Antioch University Dissertations & Theses

This study investigated factors that affect adjustment in children with life-threatening illness from the viewpoint of the parents/caregivers. The data were collected from parents/caregivers whose children have a life threatening diagnosis. Parents/caregivers were interviewed and asked to complete the Parent Request Questionnaire (PRQ) which was given to them after the in-person interview. This newly developed PRQ was utilized into prior research to predict the levels of adjustment in children. It includes age, whether the child has been informed of the diagnosis, whether the child engages in age-appropriate activities, the child's prior experience with death, the child's family's involvement in treatment, …

My Heart Is In The East: Exploring Theater As A Vehicle For Change, Inspired By The Poetic Performances Of Ancient Andalucía, Jessica Litwak

Antioch University Dissertations & Theses

This study addresses the research question “How Do I Inspire Personal and Social Change Through My Theater Practice?” I implement the theory and practice of H.E.A.T., a fusion theater system, combining use of theater arts as healing practice, educational asset, activist tool, and an art form.I research different ways that theater can affect change, focusing specifically on the use of history in performance.I dramatically interpret a period of history where performance and poetry contributed to change.I utilize qualitative methods including performance ethnography, auto ethnography, arts-based research, and historical research.I describe the fieldwork in conflict zones in the Middle East, which …
