Normal Behavioral Responses To Light And Darkness And The Pupillary Light Reflex Are Dependent Upon The Olivary Pretectal Nucleus In The Diurnal Nile Grass Rat, Andrew J. Gall, Ohanes S. Khacherian, Brandi Ledbetter, Sean P. Deats, Megan Luck, Laura Smale, Lily Yan, Antonio A. Nunez

Faculty Publications

The olivary pretectal nucleus (OPT) is a midbrain structure that receives reciprocal bilateral retinal projections, is involved in the pupillary light reflex, and connects reciprocally with the intergeniculate leaflet (IGL), a retinorecipient brain region that mediates behavioral responses to light pulses (i.e., masking) in diurnal Nile grass rats. Here, we lesioned the OPT and evaluated behavioral responses in grass rats to various lighting conditions, as well as their anxiety-like responses to light exposure. While control grass rats remained diurnal, grass rats with OPT lesions exhibited a more night-active pattern under 12h:12h light-dark (LD) conditions. However, when placed in constant darkness, …

A Proposal And Examination Of A Novel Life History And Sociometer Model Of Self-Esteem, Jin Chuan Yong

Dissertations and Theses Collection

Self-esteem occupies an esteemed position in psychological research, but the self-esteem scholarship has often raised more questions than it has answered. Recent alternative approaches to self-esteem have made decent strides in resolving the mixed findings abound in the literature, such as a call for greater focus on self-esteem’s functionality and domain-specific components of self-esteem. However, the lack of a well-grounded, parsimonious theory of self-esteem has kept these proximate theories and findings disparate and our overall understanding of self-esteem incomplete. The current dissertation sought to address these issues by developing a model of self-esteem based on the evolutionarily driven sociometer and …

Racial Bias In Judgments Of Physical Size And Formidability: From Size To Threat, John Paul Wilson, Kurt Hugenberg, Nicholas O. Rule

Department of Psychology Faculty Scholarship and Creative Works

Black men tend to be stereotyped as threatening and, as a result, may be disproportionately targeted by police even when unarmed. Here, we found evidence that biased perceptions of young Black men's physical size may play a role in this process. The results of 7 studies showed that people have a bias to perceive young Black men as bigger (taller, heavier, more muscular) and more physically threatening (stronger, more capable of harm) than young White men. Both bottom-up cues of racial prototypicality and top-down information about race supported these misperceptions. Furthermore, this racial bias persisted even among a target sample …

Trauma Therapy For Very Young Children Living In Poverty: A Randomized Controlled Trial, Joanna Ruth Love

Dissertations (1934 -)

This study used a randomized control design with immediate treatment and wait list control conditions to evaluate the efficacy of the New Hope program, a home-based, parent-and-child therapy program that has been developed for very young children living in poverty who experienced one or more potentially traumatizing events. Within a three-phase model of treatment, the New Hope program is designed to establish safety, build the caregiver child relationship, create a nurturing environment, teach coping skills, address trauma-related thoughts and feelings, and develop prosocial skills. Training in this program included discussions regarding the cultural implications of providing therapy services in the …

Inch By Inch: Making Our Gardens Grow, Rita Beck Neal, Nanci Weinberger

Applied Psychology Department Faculty Journal Articles

Why bring gardens to early education programs? School garden success has a long history, but this success has been found primarily in elementary schools (Blair 2009). Yet child care centers are typically open year-round and therefore are better prepared to enjoy the full bounty that gardens may provide.

Gardening with young children isn’t new (McFarland 2005), but a small national “farm to child care movement” that supports garden programs is growing (Berkenkamp and Mader 2012).

Unfortunately, many teachers are not familiar with gardening and plant science (Blair 2009). The novelty of gardening may be one of the obstacles in bringing …

Independent Study Project (ISP) Collection

This paper discusses the topic of mental illness stigma and treatment in Uganda as explored through internship in the Social Work Department at Butabika National Referral Mental Hospital. The objectives of this project were to complete a meaningful internship while exploring causes of mental illness in Uganda, contradictions between traditional and modern approaches to treatment, and the affect of stigma on mental well-being. The internship included a total of 120 hours at Butabika Hospital. Individual research using documentary and literature review methods accompanied the internship. Butabika Hospital did not consent to the completion of formal research at, so any conclusions …

Aging, Executive Function, Fronto-Parietal Network Cortical Thickness: Insights From Cognitive Reserve, Katherine Reiter

Dissertations (1934 -)

Cognitive reserve (CR) indexes the nonlinear relationship between neurological insult and behavioral change. CR is manifested in both static factors (e.g., childhood environment, education) and modifiable lifestyle factors, (e.g., leisure activities). Detailed investigation of the influence of CR on cortical thickness, which indexes neuropathology, and cognitive functioning could be particularly important in understanding the heterogeneity of Alzheimer’s disease (AD). While memory decline is the hallmark of AD, executive functioning (EF) decline often predates memory changes, making EF an important target for investigating CR influences. The current study examines the relationship of CR and genetic risk for AD (ε4) on EF …

The Effects Of Income And Ethnicity On Health Outcomes Of Mexican Immigrant And Anglo Women, Andrea M. Debarros

Theses and Dissertations

The Hispanic Paradox is the finding that Hispanic immigrants living in the United States have better health than Anglo Americans despite being socioeconomically disadvantaged (Crespo et al., 1996; Stern et al., 1999; Sundquist et al., 1999; Dixon et al, 2000; Lariscy et al., 2015; Overton et al., 2015; Thomson et al., 2013). The literature surrounding the Hispanic Paradox has studied these effects primarily in Mexican-American Immigrant populations (Sundquist et al., 1999; Dixon et al, 2000; Lariscy et al.); however, additional research has found similar findings for various other Hispanic countries such as Cuba and Puerto Rico (Abraido-Lanza, A F. et …

Attitudes And Actions That Adoptive Parents Perceive As Helpful In The Process Of Raising Their Internationally Adopted Adolescent, Marina V. Kuzmina

This phenomenological dissertation study explored the lived experiences of adoptive parents in the process of raising their internationally adopted adolescents. The researcher interviewed 9 participants. Criteria for selection of the research sample included having personal experience with parenting one or more international adolescents adopted at age 10 or older and raising these adolescents for at least two years following such adoption. Data analysis included steps suggested by Moustakas (1994) and the participation of a research team and external auditor. According to the recommendations of Lincoln and Guba (1985), several strategies for trustworthiness were implemented during this course of the study. …

Parent Perceptions Of Treatment Effectiveness And Attendance Rates In A Behavioral Parent Training Program: Do They Predict Treatment Outcomes For Children?, Natalie A. Hofmann Leedy

USF Tampa Graduate Theses and Dissertations

Young children who display disruptive behaviors are at risk for negative outcomes in later development such as school dropout, early pregnancy, and unemployment (Bradshaw, Schaeffer, Petras, & Ialongo, 2010). For this reason, it is imperative parents of children with disruptive behaviors seek early intervention to reduce problem behaviors and prevent negative effects (Breitenstein, Hill, & Gross, 2009). Parent behavioral training interventions are effective for reducing problem behaviors in young children. Attrition from parent training interventions, however, is a common problem that reduces positive outcomes for children with challenging behaviors (Kazdin, Holland, & Crowley, 1997; Prinz & Miller, 1994). Barriers to …

A New Taxonomy Of Altruism In Terms Of Prosocial Behaviors, Kristin Kaiser

Dialogue & Nexus

The definition of altruism has been studied, explained, and even confused by many scholars in various fields. The term itself has been inappropriately used to describe prosocial behaviors that do not fall within the definition of altruism. An evaluation of Grant Ramsey’s taxonomy of altruism, which includes biological altruism, psychological altruism, and helping altruism, proves that it is not adequate in categorizing organism’s behaviors. A new taxonomy, with the branches of kin selection, reciprocity, and aesthetic altruism, is presented and explained to clarify the definition of altruism and alleviate confusion about how to describe prosocial behaviors. Both naming systems are …

Effects Of An Early Life Immune Challenge On Body Growth, Personality, Mating Behaviors, And Brain Development Of Zebra Finches (Taeniopygia Guttata), Ahmet Kerim Uysal

USF Tampa Graduate Theses and Dissertations

The developmental stress hypothesis predicts that an aversive condition, such as decreased food intake, predation, and social isolation, in the early developmental stage could have long term effects on behaviors and brain development of an animal. In nature, bird nestlings are susceptible to various factors, such as malnutrition, infections, and parasites. Effects of early life stress on adulthood have been extensively studied with some stressors including malnutrition. However, immune challenges as an early life stressor and their long-term programming effects on adult behaviors are yet to be studied in detail. The goal of the current study was to investigate changes …

The Experience Of Mental Health Practitioners With Computer Games Designed To Induce Empathy, Jordan Reed

College of Science and Health Theses and Dissertations

Though mental health care providers’ primary function is to facilitate improved outcomes for their clients, providers who have stigmatizing attitudes towards mental illness can compromise therapeutic outcomes for those living with mental disorders. The therapeutic relationship is the component of care most closely tied to therapeutic outcomes, and this relationship is often jeopardized by provider stigma. Training and mid-career interventions to reduce stigma by enhancing provider empathy for persons with mental illness show varying levels of effectiveness and a majority of these use lecture based instruction. Interventions that engage mental health providers in the experience of persons with mental health …

How Social Reactions To Alcohol-Related Facial Flushing Are Affected By Gender, Relationship, And Drinking Purposes: Implications For Education To Reduce Aerodigestive Cancer Risks, Ian Newman, Lanyan Ding, Duane F. Shell, Lida Lin

Department of Educational Psychology: Faculty Publications

Alcohol-related facial flushing is a sign of compromised alcohol metabolism and increased risk of certain cancers. This project examined how facial flushing might be used to reduce alcohol use to lower cancer risks. Interviews with Chinese university students identified gender, friendship, and drinking purpose as important variables related to whether someone would encourage a person who flushes when drinking alcohol to stop or reduce their drinking. A questionnaire was developed that incorporated these variables into 24 drinking scenarios in which someone flushed while drinking. Students responded whether they would (a) encourage the flusher to stop or drink less; (b) do …

Toxoplasma Gondii Moderates The Association Between Multiple Folate-Cycle Factors And Cognitive Function In U.S. Adults, Bruce L. Brown, Andrew N. Berrett, Shawn D. Gale, Lance D. Erickson, Dawson W. Hedges

Faculty Publications

Toxoplasma gondii (T. gondii) is a microscopic, apicomplexan parasite that can infect muscle or neural tissue, including the brain, in humans. While T. gondii infection has been associated with changes in mood, behavior, and cognition, the mechanism remains unclear. Recent evidence suggests that T. gondii may harvest folate from host neural cells. Reduced folate availability is associated with an increased risk of neurodevelopmental disorders, neurodegenerative diseases, and cognitive decline. We hypothesized that impairment in cognitive functioning in subjects seropositive for T. gondii might be associated with a reduction of folate availability in neural cells. We analyzed data from the third …

Stimulus-Selectivity Of Drug Purchase Tasks: A Preliminary Study Evaluating Alcohol And Cigarette Demand, Justin Charles Strickland, William W. Stoops

Psychology Faculty Publications

The use of drug purchase tasks to measure drug demand in human behavioral pharmacology and addiction research has proliferated in recent years. Few studies have systematically evaluated the stimulus selectivity of drug purchase tasks to demonstrate that demand metrics are specific to valuation of or demand for the commodity under study. Stimulus selectivity is broadly defined for this purpose as a condition under which a specific stimulus input or target (e.g., alcohol, cigarettes) is the primary determinant of behavior (e.g., demand). The overall goal of the present study was to evaluate the stimulus selectivity of drug purchase tasks. Participants were …

Intimate Partner Violence, Perception Of Safety, And Faith Among Female College Students Attending Faith-Based Institutions, Liliya Anatolyevna Rudneva

Doctor of Psychology (PsyD)

Many women experience intimate partner violence (IPV), and research shows this violence significantly impacts their mental health, physical health, and substance abuse. The experience of IPV may also impact other areas of life. This study aims to explore the relationship between the experiences of IPV, perception of safety, and perception of faith, among female college students attending Christian universities. Archival data from the National College Health Assessment (NCHA) was used to explore this relationship among female students who experienced physical, sexual, or psychological IPV in the past twelve months. Results indicate students who experienced IPV endorsed lower perceptions of safety …

Camp-Based Intervention For Overweight Children With Developmental Disabilities, Allyson Davis

Loma Linda University Electronic Theses, Dissertations & Projects

Childhood obesity is a growing epidemic and results in negative health and psychosocial outcomes. Children with intellectual and developmental disabilities (IDD) experience increased rates of obesity compared to typically developing children, but interventions targeting health behaviors in this population have been limited. We examined the feasibility and efficacy of a health behaviors camp for children and adolescents with IDD. We also tested the correlation of child behavior problems and social skills with baseline weight status and health behaviors. Furthermore, we examined these psychosocial risk factors as moderators of camp outcomes. The camp included participants aged 9 – 15 years who …

Veterans, Ptsd Severity, And Health Conditions Over Time, Macey Mendez-Vigo Wolfe

Loma Linda University Electronic Theses, Dissertations & Projects

PTSD has been linked to the development of numerous health conditions; this study’s aim is to determine if PTSD predicts the diagnosis of type II diabetes, overweight/obesity, hypertension, musculoskeletal disorders, neurological disorders, and chronic pain. Participants were 416 veterans presenting for PTSD assessment/treatment that had served in the most recent conflicts (Operation Enduring Freedom, Operation Iraqi Freedom, Operation New Dawn, and Dessert Storm) with a mean age of 35.5 (SD = 10.9). Participants completed a measure of PTSD symptomatology. Electronic medical records were used to obtain diagnosis of health conditions. Cox-Regression analyses were used to evaluate PTSD as a predictor …

The Influence Of Health Framing On Weight Stigma And Health Knowledge, Serena D. Stevens

Loma Linda University Electronic Theses, Dissertations & Projects

With increasing rates of obesity and obesity-related health problems, recent years have seen a great deal of effort exerted to improve physical health by reducing obesity. While information about health is frequently communicated through news media, research has shown that news articles do not increase knowledge of physical health behaviors and instead increase weight stigma, which predicts decreased physical and mental health. Given that this method of presenting health information is ineffective and harmful, it is important to examine alternative ways to frame information on physical health behaviors. This study examined differential effects of three article types, Health Improvement, Weight …

Cancer Center Regional Benchmarks For Psychosocial Care, Desiree R. Azizoddin

Loma Linda University Electronic Theses, Dissertations & Projects

The American College of Surgeons (ACoS) Commissions on Cancer (CoC) formulated and implemented standard 3.2 for Psychosocial Distress Screening. This standard requires that all accredited cancer centers evaluate psychosocial distress and provide appropriate triage and intervention for all cancer patients. Over the past decade, Loma Linda University Medical Oncology Center (LLUMOC) administration, physicians, nurses, psychosocial care staff, and chaplaincy collaborated to implement a psychosocial screening and referral program throughout cancer patient services. This current research includes qualitative analysis assessing strengths and barriers of the psychosocial program at LLUMOC from the perspective of LLUMOC providers and two directors of Supportive Care …

A Descriptive Study Of The Elderly In California Substance Abuse Treatment Programs, David Berenschot

Electronic Theses, Projects, and Dissertations

As gerontologists may know, there are a great deal of studies and a variety of academic literature on the misuse of alcohol and prescription medication amongst the elderly population. While there is a plethora of information on alcohol and prescription misuse, there is little reported data about the prevalence of other substance misuse experienced by this population. This study aims to help to fill that gap in the data by using quantitative methods to describe the scope of substance abuse of individuals 55-years or older. This study utilizes data from the Treatment Data Set Admission (TEDS-A). The TEDS-A is a …

The Relationship Between Physical Activity, Depressive Symptoms, And Cognitive Functioning, Imari-Ashley F. Palma

Loma Linda University Electronic Theses, Dissertations & Projects

The number of older individuals experiencing age related cognitive decline (ARCD) continues to grow exponentially. Memory, executive functioning, and cognitive processing speed have shown to be particularly sensitive to the effects of aging. The same regions of the brain associated with executive functioning and memory are also associated with mood. Researchers have shown an association between ARCD and depression. Research on physical activity (PA) continues to show a beneficial influence on cognition, physical health, and mood. Developmentally, women and men have normal differences in cognitive functioning. As women and men age, these differences can increase. In addition, researchers have shown …

Profiles Of School Readiness And Implications For Children's Development Of Academic, Social, And Engagement Skills, Elizabeth Jane Tremaine

Dissertations and Theses

Academic achievement gaps across racial, ethnic, and socioeconomic groups are apparent as soon as children enter kindergarten: racial minorities, Hispanics, and poor children begin school at a distinct disadvantage compared to their White peers from middle- and high-income families (Chatterji, 2005; Fryer, Jr. & Levitt, 2004; Magnuson, Meyers, Ruhm, & Waldfogel, 2004; Magnuson & Waldfogel, 2005; Reardon, 2011). To understand these gaps at kindergarten entry, it is essential that researchers understand the skills with which children enter kindergarten.

Previous research on school readiness has been limited by variable-centered methods that separate components of school readiness (e.g., early academic skills, social …

Attitudes And Preferences About The Stepped-Care Model Of Depression Treatment In Oncology: A Pilot Study, Juliana Alessandra D'Onofrio

Theses and Dissertations

The current pilot study examines the feasibility of conducting a full-scale study that utilizes a survey-based cross-sectional methodological design. The purpose was to systematically explore the attitudes about the Stepped-Care (SC) Model of depression treatment, specific treatment preferences for depression, and client characteristics of a sample of women diagnosed with breast cancer. A total of 26 women were recruited from a breast cancer clinic located in the Northeastern United States. Preliminary results indicated that participants on average rated treatments within the SC Model as acceptable, tended to prefer step three (e.g. psychotherapy, medication, or a combined approach) or step two …

Fast Food, Slow Brain: The Effect Of Diet On Brain Volume, Kayla Alder, Dr. Brock Kirwan

Journal of Undergraduate Research

The hippocampus is a brain structure in the medial temporal lobe that mediates the encoding of sensory information into long-term memory (Squire, Clark, & Stark, 2004). Studies have found a relationship between the volume of the hippocampus and behavioral memory tests; that is, the smaller the volume of the hippocampus, the less accurate the performance on memory tests (Rajah, Kromas, Han, & Jens, 2010). Previous research also demonstrates that a high fat and sugar (HFS) diet impairs the hippocampus and affects memory (Francis & Stevenson, 2011).

Examining The Relationship Between Self-Efficacy And Health Behaviors Among College Students, Brent D. Fisk

Doctor of Psychology (PsyD)

Adolescents’ transition into adulthood often coincides with significant developmental change processes. Behavioral patterns established during this period can determine risk and quality of life trajectories (Ben-Shlomo & Kuh, 2002, Halfon & Hochstein, 2002). Social support facilitates health behavior change and college students have ready access to peers with shared goals. In addition to social support, self-efficacy has also been associated with student health as a protective and predictive factor of healthy behaviors (Von Ah, Ebert, Ngamvitroj, Park, & Kang, 2004). Research indicates a strong relationship between self-efficacy and health behaviors; however, the direction of causality is unclear and there is …

Telemental Health Services As A Targeted Intervention For Individuals Who Are Deaf And Hard Of Hearing, Teresa Crowe

JADARA

Deaf and hard of hearing individuals who have chronic mental illness are a population that is underserved. Like their hearing counterparts with mental illness, individuals who are Deaf and hard of hearing often face medical and treatment disparities. The purpose of this paper is to propose the use of telemental health (TMH) services, or services provided via videoconferencing technology, as a targeted intervention that may provide relief to Deaf and hard of hearing individuals with mental health problems. This paper addresses several areas that are important when considering service provision to Deaf and hard of hearing individuals, including a working …
