Object Permanence In The Dwarf Goat (Capra Aegagrus Hircus): Perseveration Errors And The Tracking Of Complex Movements Of Hidden Objects, Christian Nawroth, Eberhard Von Borell, Jan Langbein

Memory Collection

Object permanence is the notion that objects continue to exist even when they are out of an observer’s sight. In mammals, the highest stage of object permanence (Stage 6) has been observed only in primates, whereas other species have shown difficulty in following once-hidden objects, particularly when complex movements are involved. We conducted four experiments to examine the ability of dwarf goats to mentally represent once-hidden objects. In Experiment 1, we investigated whether dwarf goats are prone to commit the A-not-B or perseveration error which is commonly used as a measure for self-control. Subjects here continue to search for an …

The Divergent Effects Of Fear And Disgust On Inhibitory Control: An Erp Study., Mengsi Xu, Zhiai Li, Cody Ding, Junhua Zhang, Lingxia Fan, Liuting Diao, Dong Yang

Education Sciences and Professional Programs Faculty Works

Negative emotional stimuli have been shown to attract attention and impair executive control. However, two different types of unpleasant stimuli, fearful and disgusting, are often inappropriately treated as a single category in the literature on inhibitory control. Therefore, the present study aimed to investigate the divergent effects of fearful and disgusting distracters on inhibitory control (both conscious and unconscious inhibition). Specifically, participants were engaged in a masked Go/No-Go task superimposed on fearful, disgusting, or neutral emotional contexts, while event-related potentials were measured concurrently. The results showed that for both conscious and unconscious conditions, disgusting stimuli elicited a larger P2 than …

Sleep Hygiene Practices: A Cross Cultural Survey Of Sleeping And Dreaming In College Students, Ivan Noe Martinez Salazar

Masters Theses

There is consensus that a sizeable percentage of people in most developed countries do not obtain adequate amounts or quality of sleep. These disruptions in sleep, when chronic and severe, can lead to psychological, behavioral and health consequences. The focus on behavioral and contextual factors that impact sleep has been termed “sleep hygiene”. An on-line anonymous survey collected sociodemographic information, as well as self-reports on sleep, sleep hygiene practices and dreaming across two cultural groups (English & Spanish speaking responders). A total of 204 participants (majority of them college and graduate students) answered the survey. Both cultural groups, English and …

Participants for this study were recruited from multiple states serving …

Differential Effects Of Methylenedioxypyrovalerone (Mdpv) And Mephedrone In Rats Trained To Discriminate Mdma Or A D-Amphetamine+Mdma Mixture, Eric Louis Harvey

Masters Theses

Recent reports on the abuse of novel synthetic cathinone derivatives call attention to serious public health risks of these substances. In response to this concern, a growing body of preclinical research has characterized the psychopharmacology of these substances, particularly mephedrone (MEPH) or methylenedioxypyrovalerone (MDPV), noting their similarities to MDMA and cocaine. The present study employed drug discrimination methodology to assess the discriminative stimulus effects of MEPH and MDPV in male Sprague-Dawley rats trained to discriminate 1.5 mg/kg 3,4 methylenedioxymethamphetamine (MDMA) or a mixture of 1.5 mg/kg MDMA and 0.5 mg/kg d-amphetamine (MDMA+AMPH). After establishing dose response functions with each training …

Effects Of Altering Motivation In Pigeons Performing A Titrating-Delayed-Matching-To-Sample Task, Zachary J. Zimmermann

Masters Theses

In order to better understand the role motivating operations (MOs) serve in preceding and evoking behavior, it is useful to examine the effects of whether manipulating motivation can influence performance on tasks with known behavioral outcomes. It is well established that altered stimulus control is responsible for changes in responding on tasks of generalization and discrimination. Therefore, if stimulus control could be influenced by MOs, then perhaps stimulus discriminations could be improved by manipulating the relevant MO. To this end, the effects of altering motivation via food deprivation were examined in pigeons using a titrating-delayed-matching-to-sample task. Additional pharmacological variables (i.e., …

Psychological And Social Variables Impacting Young Adults Caring For Severely Mentally Ill Mothers, Courtney Gale Deloney

Dissertations

This dissertation study examined the psychological and social functioning of young adults who care for their severely mentally ill mothers; in doing so this study examined the independent variables coping style, perceived stress, quality of life, and resilience. The dependent variables considered were race, socioeconomic status, support group participation, and living in the same household as one’s mother. Young adulthood was examined as a distinct period of human development. The policy of deinstitutionalization led many families to become caregivers for their severely mentally ill relatives. While some knowledge on this exists, little is known about the experiences of young adult …

Tongues Untied Truth Revealed: Body Image, Social Media, Identity Development, And Meaning-Making In Overweight And Obese Black Gay Msm, Amari Ja-Lynn Enam

Dissertations

This phenomenological study explored the meanings attributed to internalized messages about body image within the context of identity development from the perspectives of overweight/obese men of African descent (OMAD) among a group of 6 men who have sex with men (MSM). I was interested in those messages that have been incorporated, adopted, or integrated into OMAD-MSM’s sense of self. Informants shared body image-related experiences from interactions with family, friends, dating/sex partners, and the media/social media.

Academic literature has explained identity development processes among African Americans through various lenses but research has not adequately explored the convergence of multiply oppressed social …

Disaster Relief And Psychological First Aid, Jenny Haeyeon Cho

Loma Linda University Electronic Theses, Dissertations & Projects

Many organizations that assist in the aftermath of disasters often do not provide psychological relief. Although people tend to be rather resilient in the face of traumatic events, the psychological distress and possible psychopathology that can ensue should not be taken lightly. This manual was created to be used as a training tool for those involved in disaster relief and aid work. A review of the literature, mental health disorders, basic information about disasters, common stress reactions, and Psychological First Aid are included. Although Psychological First Aid has not really been systematically studied, it appears to be promising in aiding …

Psychological Services For Pediatric Victims Of Non Accidental Trauma, Robyn Finckbone

Loma Linda University Electronic Theses, Dissertations & Projects

Child abuse is a significant problem within our society. In 2010, there were approximately 1,560 fatalities as a result of child abuse; 17.6% of those deaths were the direct result of physical abuse and 80% occurred in children under the age of 4. There is a dearth of research examining severe physical abuse among children and, as a result, the demographics of this population are unclear as are the psychological referrals and services provided to these children. The aims of the current study are to identify the demographic characteristics of child victims of non-accidental trauma (NAT, i.e. physical abuse) as …

Cultural Beliefs And Self-Efficacy In Diet Adherence Among Type 2 Diabetics, Sonika Kravann Ung

Loma Linda University Electronic Theses, Dissertations & Projects

Type 2 Diabetes (T2D) is a global epidemic that disproportionately affects socioeconomic and ethnic minority populations (International Diabetes Federation, 2013). Mapuches, the largest Native American population in Chile, shifted from the lowest incidence of T2D to equal rates in comparison to mainstream Chileans within a decade (King & Rewers, 1991; Perez-Bravo et al., 2001). This may be due to economic growth and rapid nutritional shifts (Yu & Zinman, 2007). Previous research has identified the importance of cultural beliefs in explaining health behavior (Betancourt, Flynn, & Ormseth, 2011). This study, guided by Betancourt’s Integrative Model for Culture, Psychological Factors and Behavior …

Adolescents' Perceptions Of Homophobic Language: Implications For Bullying Prevention, Benjamin M. Bailey

Theses and Dissertations

Large scientific studies have recognized homophobic language as a national concern (American Association of University Women [AAUW], 2001; Kosciw, Greytak, Diaz, & Bartkiewicz, 2010). Concerning perceptions of homophobic language use, quantitative studies were mostly conducted in specific areas of the United States and qualitative studies have largely approached the issue with the theory of masculinity. The current study proposed to approach the study actively challenging all assumptions about homophobic language use. This study assimilated 20 adolescents' perceptions of homophobic language, using a hermeneutic qualitative methodology. This study found that in addition to policing masculinity, homophobic language was used to police …

Assessing Validity Of A Screener For Social, Emotional, And Behavioral Concerns: Analyzing Gender Differences In A Middle School Population, Kimberly Lowe

Theses and Dissertations

Systematic screening for social, emotional, and behavioral concerns (SEBC) identifies at-risk students and provides information to guide interventions that may prevent negative outcomes (Glover & Albers, 2006; Kauffman, 1999; Severson, Walker, Hope-Dolittle, Katochwill, & Gresham, 2007). However, the screening process may be influenced by the gender of the student (Young, Sabbah, Young, Reiser, & Richardson, 2010). This study further examined the influence of student gender on screening by assessing the congruency of gates one and two of a screening process based on student gender. Participants included 59 middle school teachers who nominated at-risk students on the Teacher Nomination Form (TNF; …

The Moderating Role Of Parental Warmth On The Relation Between Verbal Punishment And Child Problem Behaviors For Same-Sex And Cross-Sex Parent-Child Groups, Maria Roberta L. Anonas, Liane Peña Alampay

Psychology Department Faculty Publications

This study investigates the relation between parental verbal punishment and externalizing and internalizing behavior problems in Filipino children, and the moderating role of parental warmth in this relation, for same-sex (mothers-girls; fathers-boys) and cross-sex parent-child groups (mothers-boys; fathers-girls). Measures used were the Rohner Parental Acceptance-Rejection and Control Scale (PARQ/Control), the Achenbach Child Behavior Checklist (CBC), and a discipline measure (DI) constructed for the study. Participants were 117 mothers and 98 fathers of 61 boys and 59 girls who responded to a discipline interview, the Parental Acceptance-Rejection and Control scale (PARQ/Control) and the Achenbach Child Behavior Checklist via oral interviews. Hierarchical …

A Sibling Support Group For Children With A Sibling With Autism, Audrey G. Venegas

Electronic Theses, Projects, and Dissertations

The purpose of this project was to create a research‑based sibling support group for 7 to 12 year‑old children who have a sibling with autism. Typically‑developing children (N = 3) and their parents attended a four‑week, once‑weekly sibling support group. The program focused on topics found to be the key issues of typically‑developing siblings who have a sibling with autism: discovering that others share similar family circumstances, learning about their sibling with autism’s special needs, discussing issues and problems children with siblings who have ASD typically face (and developing effective coping strategies to deal with these issues), and having an …

Recently, a mental health museum and archive of artifacts, photographs, and documents was established on the grounds of Patton State Hospital in Highland, California. The purpose of this paper is to reflect on the establishment of this museum and archive and to provide an account of the 125 year history of Patton State Hospital. Understanding the history of Patton provides an opportunity to understand the history of mental health care in the United …

Interactions Between Social Support, Acculturationand Health Among Mexican Immigrants, Christopher D. Anderson

Theses and Dissertations

The impact of acculturation and poor social support as potential risk factors for cardiovascular and metabolic disease amongst Mexican immigrants to the United States (U.S.) is a developing area of research. One theory is that acculturation to U.S. society is negatively associated with health due to the stress of immigration as well as the less healthy diet and lifestyle in the U.S. It is also theorized that positive social support is associated with better health during immigration due to the buffering effect relationships have on stress. Despite these theories, mixed findings have been found regarding the associations between acculturation and …

Electrophysiological Endophenotypes In Autism Spectrum Disorder: A Family Study, Ann Clawson

Theses and Dissertations

Autism spectrum disorder (ASD) is a highly heritable neurodevelopmental disorder associated with altered neural connectivity and deficits in self-monitoring, response inhibition, and planning. One promising avenue of research to improve understanding of the symptoms and heritable nature of ASD may be the identification of neural endophenotypes of ASD. The error-related negativity (ERN) and post-error positivity (Pe), scalp-recorded event-related potentials (ERPs), reflect performance monitoring processes and may qualify as candidate endophenotypes of ASD. We collected ERP and behavioral data (error rates, response times) from 18 ASD probands and their families (mother, father, sibling) and 38 control youth and their parents to …

The Relationship Between Attachment And Depression: The Mediational Role Of Shame, Self-Esteem, And Social Support, Evelyn Estela Ayala

Electronic Theses, Projects, and Dissertations

According to the American College Health Association 31.3% of college students reported feeling depressed. Early parental attachment forms an internal working model that is used as reference for later relationships and experiences. Past research suggests that parental attachment is associated with depression. Low self-esteem was found to mediate the relationship between parental bonding (low care and overprotection) and depression. The cognitive schemas of defectiveness and shame were found to meditate the relationship between poor parental bonding and depression. Among cancer patients the relationship between anxious attachment and symptoms of depression was mediated by perceived social support.

Research is necessary to …

Transgenerational Transmission And The Relationship Between Parents With Symptoms Of Post-Traumatic Stress Disorder And Their Children With Symptoms Of Attention Deficit Hyperactivity Disorder, Donald Dean Campany

Doctoral Dissertations and Projects

This study examined parental symptoms of posttraumatic stress disorder (PTSD) and its effects on children referred for treatment with symptoms of attention deficit hyperactivity disorder (ADHD). Data was collected from children who had been diagnosed ADHD. This research attempted to determine whether negative family functioning can be predicted between caregivers with symptoms of PTSD and their children with symptoms of ADHD, and whether PTSD caregiver’s behavior is an indication of ADHD like symptoms in their children. Results revealed that there was a not a significant difference in behavior of children with symptoms of ADHD when compared to parents with symptoms …

Take The Monkey And Run, Kimberley A. Phillips, M. K. Hambright, K. Hewes, B. M. Schilder, C. N. Ross, S. D. Tardif

Psychology Faculty Research

The common marmoset (Callithrix jacchus) is a small, New World primate that is used extensively in biomedical and behavioral research. This short-lived primate, with its small body size, ease of handling, and docile temperament, has emerged as a valuable model for aging and neurodegenerative research.

A growing body of research has indicated exercise, aerobic exercise especially, imparts beneficial effects to normal aging. Understanding the mechanisms underlying these positive effects of exercise, and the degree to which exercise has neurotherapeutic effects, is an important research focus. Thus, developing techniques to engage marmosets in aerobic exercise would have great advantages.

Executive Functioning And Risk For Alzheimer's Disease In The Cognitively Intact: Family History Predicts Wisconsin Card Sorting Test Performance, Kathleen Hazlett, Christina Marie Figueroa, Kristy A. Nielson

Psychology Faculty Research and Publications

Alzheimer’s disease (AD) research typically focuses on memory. However, executive functioning (EF) deficits are also common among AD patients; these deficits are associated with decreased functioning in activities of daily living, an important criterion in diagnosing AD. A classic test of EF ability, the Wisconsin Card Sort Test (WCST), has demonstrated sensitivity to differentiating individuals with AD from healthy controls, discriminating AD groups based on disease severity, and distinguishing AD from other types of dementia. Such sensitivity to AD raises the possibility that the WCST is also sensitive to very early, preclinical differences between those who have heightened risk for …

The Adaptive Value Associated With Expressing And Perceiving Angry-Male And Happy-Female Faces, Peter Kay Chai Tay

Research Collection School of Social Sciences

Facial expressions are valuable for conveying and understanding the inner thoughts and feelings of the expressor. However, the adaptive value associated with a specific expression on a male face is different from a female face. The present review uses a functional-evolutionary analysis to elucidate the evolutionary advantage in the expression and perception of angry-male and happy-female faces over angry-female and happy-male faces. For the expressors, it is more advantageous for men to show angry facial expression as it signals dominance, averts aggression and deters mate poaching; it is more advantageous for women to display happy facial expression as it signals …

The Unspoken Truth: A Practical Guide For Pastors, Helping Abusers Break The Cycle Of Sexual Abuse, Teresa Johnson

Doctoral Dissertations and Projects

For years, men, women and children have suffered silently as a result of sexual abuse. The abuser suffers and the cycle continues. Destroying the silence of sexual abuse is the beginning of breaking the cycle. Research has shown that the abuse goes far beyond the actual act and causes physical, emotional, and psychological damage. This project will investigate and encourage open discussion, address the abuse, and give valuable insight to the causes and consequences of sexual abuse. This project will offer prescriptive and preventative measures to all parties involved, in an effort to heal and stop sexual abuse. Through research …

The Effects Of Childhood Sexual Abuse On Parenting, Erin Ann Williams

Dissertations, Theses, and Capstone Projects

Childhood sexual abuse (CSA) is a pervasive problem that has been the focus of substantial empirical research. While negative outcomes such as psychiatric diagnoses or health problems have been well documented, the literature regarding the effects of CSA on parenting is sparse and has produced conflicting results. Moreover, the existing research on CSA's effect on later parenting has several methodological limitations (e.g., retrospective data) and has failed to find any consistent explanatory mechanisms/pathways for which CSA is most likely to impede parental success. The present study examined whether a history of CSA leads to negative parental outcomes (i.e., how they …

Do Cultural And Perceptual Factor Matter?: An Investigation Of Factors Impacting Intelligence Test Scores Of Latinos/Hispanics In The United States, Mary E. Ignagni

Dissertations, Theses, and Capstone Projects

This paper examined societal and cultural explanations regarding the score differences seen between Latinos/Hispanics and Whites on intelligence tests through focusing specifically on possible explanations for the scores obtained by Latino/Hispanic test-takers. In this paper, it was argued that additional unique factors may impact the test scores of Latino/Hispanic test-takers. Specifically, racial and ethnic self-identification, ethnic centrality, acculturation, cultural distance, test perceptions, and ethnicity were explored as possible unique factors. In addition, an attempt was made to explain within group differences. A non-experimental study was utilized in which a final sample of 194 participants completed an intelligence test and measures …

Testing Visual Ecology Hypotheses In Avian Brood Parasite-Host Systems: The Role Of Uv-Light Perception And Egg-Nest Contrast In Foreign Egg Rejection, Zachary Aidala

Dissertations, Theses, and Capstone Projects

Color signals are highly important features of animal communication systems, particularly among birds, which possess exquisitely complex visual perception systems. Birds possess tetrachromatic vision, and some species are sensitive to ultraviolet (UV) wavelengths. Because human and avian visual systems dramatically differ (i.e. humans are not sensitive to UV wavelengths), biologically relevant sensory models are necessary to accurately assess the function of avian color signals. In this dissertation, I primarily use brood parasite-host interactions as a model for studying the behavioral function of avian-perceivable visual stimuli. In Chapter 1, I review the importance of employing biologically relevant sensory-perceptual visual models when …

Electrophysiological Markers Of Short-Term Visual Adaptation: An Examination Across The Schizophrenia Spectrum, Gizely N. Andrade

Dissertations, Theses, and Capstone Projects

The experiments comprising this dissertation sought to contribute to the understanding of basic sensory processing in schizophrenia-spectrum disorders and risk-liability. We leveraged the sensitivity of visual processing deficits along with widely reported sensory-gating deficits (in other modalities) to develop a new paradigm assaying short-term visual adaptation to repetitive stimuli. In the first experiment, adaptation properties of the visual system were characterized in neurotypical adults using a classic "paired adaptation paradigm" and a more taxing "block adaptation paradigm," using high-density EEG. In the second experiment, we deployed our new visual adaptation assay in a clinical population. We replicated classic early VEP …

The Relationship Between Social-Emotional Development, Academic Achievement And Parenting Practices In Young Children Who Attend Head Start, Emily A. A. Dow

Dissertations, Theses, and Capstone Projects

During the preschool years, children develop social-emotional skills -- such as cooperation and self-regulation -- which predict later academic achievement. Research shows that parents play an important role in the development of these skills. However, it remains unclear how specific parenting practices may facilitate the relationship between social-emotional development and academic success. Often, children who grow up in low-income families are at risk for a variety of cognitive and emotional problems. Head Start is a federal program offered to low-income families that provides services, including early childhood education programs, to help offset these risks. Using Bronfenbrenner's bioecological theory, the purpose …

Negative Cognitive Style, Rumination, And Negative Emotionality As Mediators Of The Antidepressive Effects Of Physical Activity Among Young Adults, Kara Pegram

Clinical Psychology Dissertations

Abstract

This study assessed whether three potential cognitive and affective mechanisms mediated the relationship between physical activity and depressive symptoms. Participants were 143 young adults between the ages of 18 and 29 (M = 19.29, SD = 1.65); the majority of participants were female (72%) and Caucasian (69.9%). Participants were followed across eight weeks and completed measures of trait and state rumination, negative emotionality, cognitive style, depressive symptoms, and physical activity. A mediated model was proposed hypothesizing negative association between physical activity and depression mediated by less rumination, negative emotionality, and cognitive style. Hypotheses were examined cross-sectionally and prospectively. …
