The Effects Of Seizure Modeling And Polyphenols On Behavior In Bang-Sensitive Drosophila, Alphonso A. Smith

Loma Linda University Electronic Theses, Dissertations & Projects

Epilepsy is a worldwide public health concern associated with debilitating neurological, cognitive, and psychosocial consequences. Current antiepileptic drugs can have debilitating side effects and new treatments are needed for individuals with pharmaco-resistant seizures like those observed in temporal lobe epilepsy (TLE). Ellagic acid (EA), a polyphenol present in several fruits and nuts, has shown beneficial effects in rodent models of epilepsy and anxiety, possibly mediated through GABAergic pathways. Bang-Sensitive Drosophila mutants model epileptic seizures following mechanical shock and provide a high-throughput alternative to costly rodent studies. The objectives of this study were to: 1) examine the effectiveness of seizure modeling …

Stress, Depression, Social Support, And Help-Seeking In College Student-Athletes, Clint H. Norseth

Loma Linda University Electronic Theses, Dissertations & Projects

Student-athletes have been identified as a distinctive sub-population in universities and colleges that face unique stressors and pressures that may put them at risk for developing mental health problems, including depression, when compared to student non-athletes. However, student-athletes have been found to seek help from mental health professionals less often than student non-athletes. Studies of college students in the general population have shown that social support networks can play an important part in “buffering” or moderating the effect of stress on both depression and help-seeking, which may also be the case for student-athletes. The purpose of the current study is …

The Effect Of Language On Cognition In An Acculturated American Sample Of Healthy Older Adults, K'Dee D. Elsen

Loma Linda University Electronic Theses, Dissertations & Projects

Background: Older adults are not only the fastest growing segment of the population (~841 million worldwide) and continually increasing, but are of special concern due to the numerous age-associated deficits, especially those on cognition. Research indicates that knowing multiple languages may act as a protective factor against the deleterious effects of cognitive aging. Objective: The purpose of the current study is to examine whether multilingualism protects against the effects of cognitive aging on the domains of executive functioning, linguistic processing, attention, memory, and visuospatial functioning. Methods: Participants were 312 healthy older adults (68% female) from the Walnuts and Healthy Aging …

The Effects Of Poverty And Allostatic Load On The Development Of Chronic Disease, Natali Do

Loma Linda University Electronic Theses, Dissertations & Projects

Research suggests that there is a significant impact of poverty on poor health outcomes. Poverty is associated with limited access to education and healthcare, increased exposure to violence, and chronic stress that contribute to the development of chronic diseases. The poverty and chronic disease relationship is potentially associated with chronically elevated stress biomarkers. The present study investigated the relationship between demographics, poverty (during childhood, young adulthood, and mid/late adulthood), allostatic load—a cumulative measure of system dysregulation—and the Charlson Comorbidity Index, a measure of chronic disease and mortality, using data from the Biopsychosocial and Religion and Health Study (BRHS; Lee et …

Erp And Theta Activity Associated With Facial Emotion Memory, Shaina Roxanne Herman

Loma Linda University Electronic Theses, Dissertations & Projects

Facial emotion recognition is an important component of daily functioning and is highly connected to the social element of human interaction. At present, it is not clear whether initial stimulus encoding or memory maintenance of the face promotes accurate facial emotion memory. The purpose of this study was to explore the mechanisms of facial affect memory. Specifically, we aimed to compare whether type of emotion, length of delay interval, or robustness of encoding the initial stimulus were associated with accurate facial emotion recognition and memory. A task of explicit emotion memory was given to 30 participants. A visual stimulus of …

Parental Stress, Emotion Regulation, Meta-Emotion, And Changes Following An Mbsr Intervention, Yangmu Xu

Loma Linda University Electronic Theses, Dissertations & Projects

Parents of children with developmental delays (DD) have consistently reported higher rates of parental stress (Dabrowska & Pisula, 2010; Oelofsen & Richardson, 2006). Difficulties with child emotion regulation are often exhibited among children with DD, and the relationship between parental stress and child emotion regulation may be bidirectional. Previous studies have found that underlying thoughts about parent’s own emotions is an important construct that has a direct impact on parental emotional wellbeing and child emotion regulation (Gottman et al., 1996). Furthermore, previous studies suggest that Mindfulness-Based Stress Reduction (MBSR), an empirically supported stress-reduction intervention, is efficacious in reducing parenting stress …

Role Of Cultural And Psychological Factors Influencing Diabetes Treatment Adherence, Sonika Kravann Ung

Loma Linda University Electronic Theses, Dissertations & Projects

Chronic diseases are the leading causes of disability worldwide although health complications can be prevented with lifestyle change (CDC, 2013). Type 2 diabetes is a growing global epidemic, and its prevalence is predicted to increase from 6.4% (285 million adults) in 2010 to 7.7% (439 million adults) by 2030 (Shaw, Sicree, & Zimmet, 2010). Given the reality of cultural diversity in contemporary society, the aim of this study was to address the need for research that integrates both cultural and psychological factors with behaviors central to diabetes control among culturally diverse populations (Betancourt & López, 1993; Betancourt, Flynn, Riggs, & …

Aberrant Salience And Probabilistic Reasoning In Distressing Attenuated Positive Psychotic Symptoms: An Examination Of A Two Factor Model, Huw Green

Dissertations, Theses, and Capstone Projects

Theoretical psychological models of positive psychotic symptoms have increasingly emphasized the interaction of multiple cognitive factors. Research into delusions in particular has focused on the interaction of two factors; a perceptual anomaly that gives rise to a need for explanation, and a bias toward premature acceptance of a hypothesis. Recently this two factor approach has been applied to positive psychotic symptoms more broadly. Two candidate factors have received extensive theoretical and empirical interest. The aberrant salience hypothesis posits that salience regulation, mediated by dopamine, goes awry in psychosis, giving rise to a generalized sense of undue significance that is applied …

Who Posts Selfies And Why?: Personality, Attachment Style, And Mentalization As Predictors Of Selfie Posting On Social Media, Nancy Adler

Dissertations, Theses, and Capstone Projects

This study examines the phenomenon of selfie posting on social media and its relationship to narcissism, the Dark Triad, impulsivity, attachment style, rejection sensitivity, and reflective functioning. The sample was made up of 499 participants who completed an online survey consisting of personality measures and open- and closed-ended questions about selfie posting behavior. Data were analyzed using a negative binomial regression model.

Results: The study found that individuals with high levels of the Dark Triad trait of psychopathy post more selfies on social media than do individuals with low levels of the trait. The Dark Triad trait of narcissism was …

Are You With Me? The Impact Of Losing A Conversation Partner’S Attention To A Mobile Device, Zachary A. Geller

Dissertations, Theses, and Capstone Projects

This study examined the impact of a cell phone interruption on participants’ emotional experience during a conversation, using the Thematic Apperception Test (TAT) (Murray, 1943) as a measurement instrument. The study explored whether or not, after losing their conversation partner’s attention to a cell phone, subjects would: tell stories reflecting less adaptive representations of relationships with oneself and others, as measured using a social cognition and object relations rating, SCORS (Stein et al, 2011); tell stories containing more negative emotional words, as measured using a linguistic inquiry software, LIWC (Pennebaker, 2001); and tell stories containing fewer words total.

Dreams And The Maternal Imaginary: From Nostalgic Intersubjectivity To Mourning, Julie Ackerman

Dissertations, Theses, and Capstone Projects

This dissertation concerns the history of psychoanalytic thinking about dreams. It is about both the psychic function of dreams and their theoretical function, or the function that they have served within psychoanalytic discourse. It begins with a consideration of the significance of the dream in classical thinking, where it was conceptualized as a psychic emergence in the context of maternal absence. It traces the way in which the rise of object relational paradigms led to the reconceptualization of the dream in relation to the presence of the maternal mind rather than the absence of the maternal body. It describes how …

Activation And Habituation Of The Cingulate Cortex During Emotion Processing In Healthy Controls, Borderline, And Schizotypal Personality Disorder, Emily Balevich

Dissertations, Theses, and Capstone Projects

Disturbances in emotional functioning are central features of the clinical profiles of both borderline and schizotypal personality disorder (BPD and SPD, respectively). BPD is characterized by a high sensitivity to emotional stimuli and unusually strong and long-lasting reactions, indicative of impaired habituation to emotional stimuli (Linehan, 1993). Previous research suggests that SPD patients demonstrate limbic hyper-reactivity to unpleasant stimuli, at least initially, but intact habituation to repeated presentation of unpleasant stimuli (Hazlett et al., 2012). The cingulate cortex supports various aspects of emotion processing and regulation, and abnormalities of this region have been related to emotion dysfunction in SPD and …

The Contributions Of Child And Romantic Attachment To Sleep Quality, Karen Estefane

Dissertations, Theses, and Capstone Projects

Little is known about the relation between attachment and sleep, although both develop around the first year of life and mutually influence each other. Furthermore, attachment styles and dimensions have been associated with sleep difficulties in both childhood and adulthood. However, these findings have not been consistent, especially among dismissing individuals. In addition, the specific contributions of both child and romantic attachment to sleep quality have not been investigated thus far. This cross-sectional study aims to examine the ways child and romantic attachment are associated with sleep quality. A sample of 671 heterosexual residents of the United States, aged 18 …

The Impact Of Spirituality And Trauma On Appraisals Of Psychotic-Like Experiences, Kathleen Isaac

Dissertations, Theses, and Capstone Projects

Background: A substantial portion of the general population (2.5% to 31.4% internationally) reports psychotic-like experiences, which are paranormal, psychic or bizarre perceptual experiences such as voice hearing, or holding strong beliefs (i.e. superstitions) that are neither experienced as pathological nor indicative of a psychotic disorder. Cognitive models of psychosis suggest that the cognitive appraisal (i.e. personal interpretation) of the experience may help distinguish non-clinical psychotic-like experiences from clinical psychotic symptoms. This dissertation attempted to add to cognitive models by assessing whether cultural and personal factors such as spirituality and trauma inform the appraisals of anomalous experiences. This study used a …

Psychoanalysis And Modernity: A Failure To Find Relief From Existential Terror, Erin Liat Claridge

Dissertations, Theses, and Capstone Projects

This project considers the ways in which culture—the symbols and institutions that guide behavior and provide meaning to the individuals living within a community—serves a defensive function against conscious awareness of existential terror. The term existential terror refers to the cognitive and emotional experience of recognizing the inevitability of death, which is often accompanied by feelings of angst, isolation from others, and awareness of meaninglessness. In this dissertation, I will argue that the broad shift from traditional culture based on Judeo-Christian religious beliefs and communal forms of social life to modernity represents a slow but destabilizing deterioration of the defensive …

Making Sense Of Missing Sessions: Attendance Patterns In Posttraumatic Stress Disorder And Substance Use Disorder Treatments, Margaret Rauen

Dissertations, Theses, and Capstone Projects

The current study examined the diverse ways individuals with co-occurring Posttraumatic Stress Disorder and Substance Use Disorders (PTSD-SUD) attend treatment. The study was a secondary analysis of a randomized controlled trial for PTSD-SUD (Ruglass et al., 2017), in which participants meeting criteria for both PTSD and SUD (N=82) were randomized to either Concurrent Treatment of PTSD and SUD using Prolonged Exposure (COPE: n=39) or Relapse Prevention Therapy (RPT: n=43). Latent class growth analysis (Muthén & Muthén, 2000) revealed three distinct classes of attendance as the model of best fit. Diagnostic, but not demographic, variables were significantly associated with treatment attendance …

Women Who Perpetrate Partner Violence: The Role Of Attachment Insecurity And Emotion Regulation, Diana Adele Robinson

Electronic Theses, Projects, and Dissertations

Intimate partner violence (IPV) is a prevalent and destructive social problem affecting millions of people around the world. Although partner violence has been widely examined among women, few studies have focused on women in the role of perpetrator. The purpose of this investigation was to identify the underlying mechanisms of IPV perpetration among college women. Specifically, we investigated the relationship among attachment insecurity (i.e., anxious and avoidant), emotion regulation (ER) strategies (i.e., expressive suppression and cognitive reappraisal), and IPV among a sample of college women. Participants (N = 177) were recruited from a Southern California university and completed measures …

Criminal Responsibility: Meta-Analysis And Study Space, Lauren E. Kois

Dissertations, Theses, and Capstone Projects

Criminal responsibility (CR; i.e., sanity) has garnered significant research attention over the years. While some variables predicting insanity outcomes are consistent, others are not. Study-level characteristics, such as sample selection, variability in the operational definition of insanity, or other unknown influences may explain discrepant findings. It is critical to consolidate these variables and systematically assess differences in methodology to understand the state of the literature and to guide future research. As such, I conducted the first meta-analysis and study space analysis (see Malpass et al., 2008) in this area. Only 16 studies met inclusion criteria for the meta-analysis. Summary effects …

Smoking, Adhd, And Problematic Video Game Use: A Structural Modeling Approach, Hyo Jin Lee

Loma Linda University Electronic Theses, Dissertations & Projects

Problematic video game use (PVGU), or addiction-like use of video games, is associated with negative physical and mental health problems as well as problems in social and occupational functioning. Possible contributors to PVGU include frequency of play, cigarette smoking, and ADHD. The aim of the current study was to explore the relationships among PVGU, cigarette smoking, ADHD, and frequency of play simultaneously using a structural modeling approach. Secondary data analysis was conducted on 2,801 video game users (Mage = 22.43 years, SDage = 4.7; 93% male) who completed an online survey comprising measures of PVGU, ADHD symptomatology, smoking behavior, and …

The Role Of Temporal Distraction On Short-Term Memory And Delayed Recognition, Susanna Luu

Loma Linda University Electronic Theses, Dissertations & Projects

Memory is a complex process that requires the translation of information from an external sensory experience into an internal representation. Once information has been translated into memory, there is little agreement regarding the cognitive structure of memory storage and maintenance. Baddeley (1966) developed a model based on a multi-storage structure which suggested that as information entered through the sensory system, it was relayed by a cognitive control center and placed into storage units based on information type (i.e. auditory, visual, etc.). Baddeley’s (1966) multi-store memory model hypothesized that content translated into memory by two phases: short-term and long-term memory. More …
