The Effects Of Caffeine And Expectancy On Short Term Memory, Sara J. O'Brien

Doctoral Dissertations and Master's Theses

Although caffeine is the most widely used drug in the world, research on the effects of caffeine on mental performance tasks (especially short term memory tasks) is inconclusive. One possible explanation for this limited understanding is the lack of studies accounting for participant expectancy surrounding caffeine. This study examined the effects of caffeine dosage (0mg, 200mg, and 400mg) and expectancy related to past caffeine use (positive, negative) on short term memory span task. A two-way Analysis of Variance showed that the two independent variables (caffeine dose and expectancy), did not significantly influence the short term memory span score. However, the …

Psychosocial Problems Of Refugees: Understanding And Addressing Needs, Catherine Doren

Independent Study Project (ISP) Collection

Because all refugees have, by definition, left their country due to a “well-founded fear of persecution due to race, political opinion, ethnic origin, religion, or belonging to a particular social group,” it must be assumed that they have experienced trauma, making psychosocial problems ubiquitous among refugees (Bulbul, 2011; M. Carballo, personal communication, 29 September 2011). Research has shown that refugees often experience a range of psychosocial problems, yet research about the potential avenues for ameliorating these problems and their consequences is lacking and must be increased. Through a combination of interviews and a review of the field’s existing literature, it …

The Structure Of Client Language And Drinking Outcomes In Project Match, Tim Martin, Paulette J. Christopher, Jon M. Houck, Theresa B. Moyers

Faculty Articles

Client language during Motivational Interviewing interventions is an important predictor of drinking outcomes, but there are inconsistencies in the literature regarding what aspects of client language are most predictive. We characterized the structure of client language by factor analyzing frequency counts of several categories of client speech. The results provide limited support for a model proposed by Miller et al. (2006) and Amrhein et al. (2003) but with some important differences. While Amrhein et al. (2003) found that only increasing strength in client commitment language predicted behavior change, the current study revealed that client language preparatory to commitment predicted drinking …

Lateralization Of Emotion, Reaction Time, And Skin Conductance Responsiveness, Kimberley Erin Rose

Loma Linda University Electronic Theses, Dissertations & Projects

Bilateral presentations of brief (250 ms), unmasked emotional and neutral stimuli were examined in two experiments with primarily female samples. Reaction time and accuracy data were used to measure perception of emotion and skin conductance response (SCR) was used to measure experience of emotion. Both words and pictures were used to account for hemispheric differences in language and visuospatial dominance. Response time was faster to emotional pictures than words. Reaction time and speeded accuracy data did not support right hemisphere hypothesis (RHH) or valence hypothesis (VH) in the expected manner. Data suggested emotion caused greater interference under speeded conditions in …

Integrating The Development Of Children And Gestalt Therapy, Jennifer J. Thompson

Loma Linda University Electronic Theses, Dissertations & Projects

There are many theories that have contributed to what we know about the development of children; for instance, theoretical diversity supports the complexities of human nature. A child's developmental level will impact his ability to relate. Gestalt theory supports the child's phenomenological view by focusing on the here-and-now of what is happening in the therapeutic environment. Most of what a child will do is in response to a need or want. The child will work toward fulfilling that need. The child may develop maladaptive ways to fulfill his needs based on the environment in which he lives. Gestalt play therapy …

Horticulture Group Therapy With Mentally Ill Older Adults, Kristen J. Hill

Loma Linda University Electronic Theses, Dissertations & Projects

With a greatly increasing number of older adults due to advances in medical care, aU baby boomers in the United States will be 65 or older by 2029. As the number of older adults grows, so does the number of those with severe mental illness. Treatments are needed to address older adults with severe mental illness that include the negative side effects of medications. Due to the nature of severe mental illness, lower levels of required cognitive processing allows for those admitted to inpatient psychiatric settings to participate, including those with dementia. Horticulture therapy has proven useful to address severe …

Interpersonal Aggression Perpetration: Static And Emotion Regulation Risk Factors, Jill Panuzio

Department of Psychology: Dissertations, Theses, and Student Research

Intimate partner aggression (IPA) is a serious public health problem for both men and women in the United States. With aspirations of alleviating the significant negative effects of IPA, a substantial body of literature has been devoted to uncovering risk factors for IPA perpetration. Much of this research has focused on static, or relatively stable, factors that may influence IPA, such as life stress, distress tolerance, rumination, and jealousy. However, considering situational variables that influence individuals more proximally to aggressive acts, in conjunction with these static factors, may provide more precise prediction of partner aggression. Current theoretical and empirical work …

Does Practice Make Perfect? A Randomized Control Trial Of Behavioral Rehearsal On Suicide Prevention Gatekeeper Skills, Wendi F. Cross, David Seaburn, Danette Gibbs, Karen Schmeelk-Cone, Ann Marie White, Eric D. Caine

Psychology Faculty Publications

Suicide is the third leading cause of death among 10-24-year-olds and the target of school-based prevention efforts. Gatekeeper training, a broadly disseminated prevention strategy, has been found to enhance participant knowledge and attitudes about intervening with distressed youth. Although the goal of training is the development of gatekeeper skills to intervene with at-risk youth, the impact on skills and use of training is less known. Brief gatekeeper training programs are largely educational and do not employ active learning strategies such as behavioral rehearsal through role play practice to assist skill development. In this study, we compare gatekeeper training as usual …

Impact Of An Online Support System On Health Related Quality Of Life Among Men Diagnosed With Prostate Cancer, Daniel K. Osei

Loma Linda University Electronic Theses, Dissertations & Projects

Prostate cancer is a major public health issue worldwide and a significant cause of male cancer death in the USA. Though early screening and treatment has greatly enhanced the outcome, men diagnosed with prostate cancer face problems that compromise quality of life after treatment. Online support for prostate cancer clients is a convenient way to help because it is anonymous, inexpensive, and can be used at clients’ convenience. Yet few studies have explored how these supports impact these clients. This study used a longitudinal randomized experimental design to examine the impact of online services on quality of life of prostate …

The Development Of Future Orientation: Underpinnings And Related Constructs, Sarah J. Beal

Department of Psychology: Dissertations, Theses, and Student Research

Future orientation has been conceptualized in a variety of ways across literatures in psychology, sociology, education, and vocation. The lack of a shared definition and measurement across theoretical perspectives has resulted in a challenge in comparing findings across literatures and organizing results in a way that provides a coherent sense of how future orientation impacts later outcomes. Trommsdorff (1979) provided a comprehensive definition of future orientation that included eight dimensions: extension, detail, domain, affect, motivation, control, sequence of events, and number of cognitions. Study 1 was designed to test this definition using measures from five prominent theories of future orientation …

An Exploratory Investigation Of The Effects Of Dragon Boating On The Psychosocial Well-Being Of Female Cancer Survivors, Clara Therese Louise Vanherweg

Master's Theses

The purpose of this study was to prospectively examine the effects of dragon boat participation on the psychosocial well-being of female cancer survivors over time and compared with the population-based norms. Nine female cancer survivors belonging to the dragon boat team, SurvivOars, participated in the initial measurement process. The measurement packet was 21 page compilation of psychosocial questionnaires capturing demographics, quality of life, moods, depressive symptoms, perceived stress, self-esteem, self-efficacy, social support, physical activity levels, body image, and sedentary behaviors. After 8 weeks, 8 subjects completed the same follow-up questionnaire to assess changes in psychosocial variables over time. Scores were …

The Levels Of Analysis Revisited., Scott A Macdougall-Shackleton

Brain and Mind Institute Researchers' Publications

The term levels of analysis has been used in several ways: to distinguish between ultimate and proximate levels, to categorize different kinds of research questions and to differentiate levels of reductionism. Because questions regarding ultimate function and proximate mechanisms are logically distinct, I suggest that distinguishing between these two levels is the best use of the term. Integrating across levels in research has potential risks, but many benefits. Consideration at one level can help generate novel hypotheses at the other, define categories of behaviour and set criteria that must be addressed. Taking an adaptationist stance thus strengthens research on proximate …

Emotional Reactivity And Regulation In Current And Remitted Depression: An Event Related Potential Study, Lauren M. Bylsma

USF Tampa Graduate Theses and Dissertations

Major Depressive Disorder (MDD) is thought to be characterized by emotion regulation deficits, including decreased use of adaptive strategies such as reappraisal, but little is known about the exact nature of these deficits and whether or not they are specific to the depressed mood state. The late positive potential (LPP) is a sustained positive deflection of the event-related potential (ERP) associated with responding to emotionally-valenced stimuli, and reappraisal strategies have been found to reduce LPP magnitude in response to emotional stimuli in healthy individuals, but this effect has not been examined in MDD. This study utilized ERPs to examine emotional …

Visual Attention And Social Anxiety: Oculomotor Behavior When Threatened, Jacqueline S. Singh

Department of Psychology: Dissertations, Theses, and Student Research

A growing theoretical and research literature suggests that trait and state social anxiety can predict attentional patterns in the presence of emotional stimuli. The current study addressed some inconsistencies and gaps in the literature using eye tracking methodology. Participants with high and low trait social anxiety were randomly assigned to either give a speech or to watch a video of another individual delivering a speech (state social anxiety manipulation). Next, participants were asked to engage in a free view task in which pairs of emotional facial stimuli (angry-happy, angry-neutral, or happy-neutral) were presented for 3 s. Eye movements were monitored …

Conditions For Empathy In Medicine: A Grounded Theory Study, Hannah Barnhill Bayne

Counseling & Human Services Theses & Dissertations

Previous research in the medical setting has credited empathy with improving treatment outcomes and patient satisfaction, though operational definitions of the concept are widely varied and indicate inconsistencies in conceptualization and subsequent assessment. The purpose of this grounded theory study was to examine the role of empathy in the medical setting. A model of conditions for empathy in medicine was developed through in-depth interviews with 21 healthcare professionals, utilizing their professional experiences and perspectives to structure the multi-level model. The seven levels of the model indicate the layers of complexity inherent in facilitating optimal empathy in medicine and add to …

The Referral Process: Rural Primary Care Physicians' Perspectives On Providing Counseling Referrals, Casey N. Tallent

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The advantages to collaborative care between physicians and mental health care providers have been known for many decades. Rural primary care physicians (RPCPs) are the first professionals that most patients contact when they have a mental health concern, particularly in rural communities. It is therefore important to understand the process that occurs when a referral for counseling is made from a RPCP and the subsequent collaboration that occurs. The purpose of this qualitative study was to generate a model that provides a better understanding of the counseling referral process from the perspective of RPCPs in private practice in the Midwest. …

When Knowing Just Isn't Enough: Examining The Role Of Moral Emotions In Health Decision Making Using The Theory Of Planned Behavior, Kate Duangdao

Department of Psychology: Dissertations, Theses, and Student Research

A proposed integrated Theory of Planned Behavior (TPB) model aimed to examine the role of moral emotions and two health outcomes: prosocial behaviors and smoking outcomes. Based on Tangney’s work with shame and guilt-proneness, it was expected that those more prone to guilt would engage in more prosocial behaviors and those more prone to shame would engage in more smoking behaviors. Prosocial behaviors were found to be negatively associated with smoking outcomes. However, results suggested that guilt and shame-proneness seem to function similarly in predicting behavioral outcomes. Components within the TPB were generally positively correlated with each health outcome, however …

Exploratory Analyses Of A Developmental Conceptualization Of Insight And Treatment Outcomes Of Individuals With Serious Mental Illness In Psychiatric Rehabilitation, Ashley R. Wynne

Department of Psychology: Dissertations, Theses, and Student Research

The purpose of the present study was to further examine the relationship between adolescent psychiatric pathology and SMI by assessing the relationship between prior mental health services before the age of 18 and time of assessment on people’s insight into their illnesses. A secondary relationship between adolescent psychiatric pathology and functioning in a variety of domains before, during, and after treatment was assessed. Overall, there was an inconsistent pattern of results and partial support of hypotheses. The current study was a retrospective longitudinal study in which assessments were given to 308 participants in an inpatient psychiatric rehabilitation unit every 6 …

Why Confronting Sexism Works: Applying Persuasion Theories To Confronting Sexism, Amy Hillard

Department of Psychology: Dissertations, Theses, and Student Research

Speaking up about or confronting prejudice creates more positive attitudes, but the mechanism underlying confrontation’s prejudice reducing effect remains unclear. Based on an integration of the confronting prejudice and persuasion literatures, I expected that observing a confrontation (vs. no confrontation) reduces prejudice and discrimination; that elaborating on confrontation messages reduces prejudice and discrimination more than confrontation alone; and that elaborating on confrontation messages causes attitude change that lasts longer than confrontation alone. Participants were recruited to complete measures of sexism and feelings toward subtypes of women across three time points (i.e., pre-test, lab manipulation, and post-test). During the lab manipulation, …

Treating Trauma Survivors With Neurofeedback: A Grounded Theory Study Based On The Practices Of Experienced Mental Health Professionals, Christine L. Currie

Counseling & Human Services Theses & Dissertations

Neuroscience, the mental health field, and the concept of trauma as an underlying factor in mental and physical disorders have been inextricably linked since the inception of the mental health professions. Numerous quantitative studies have indicated that neurofeedback may be effective in ameliorating trauma symptoms; however, there is a paucity of research exploring the factors that produce those positive outcomes. The purpose of this qualitative grounded theory study was to explore the factors and processes that influence treatment outcomes when neurofeedback is used with trauma survivors. Thirty interviews were completed with ten experienced mental health and neurofeedback professionals identified through …

“What” And “Where” In Auditory Sensory Processing: A High-Density Electrical Mapping Study Of Distinct Neural Processes Underlying Sound Object Recognition And Sound Localization, Victoria M. Leavitt, Sophie Molholm, Manuel Gomez-Ramirez, John J. Foxe

Publications and Research

Functionally distinct dorsal and ventral auditory pathways for sound localization (WHERE) and sound object recognition (WHAT) have been described in non-human primates. A handful of studies have explored differential processing within these streams in humans, with highly inconsistent findings. Stimuli employed have included simple tones, noise bursts, and speech sounds, with simulated left–right spatial manipulations, and in some cases participants were not required to actively discriminate the stimuli. Our contention is that these paradigms were not well suited to dissociating processing within the two streams. Our aim here was to determine how early in processing we …

Perflurorochemical (Pfc) Exposure In Children: Associations With Impaired Response Inhibition, Brooks B. Gump, Qian Wu, Amy K. Dumas, Kurunthachalam Kannan

Falk College Research Center

Background: Perfluorinated chemicals (PFCs) have been used widely in consumer products since the 1950s and are currently found at detectable levels in the blood of humans and animals across the globe. In stark contrast to this widespread exposure to PFCs, there is relatively little research on potential adverse health effects of exposure to these chemicals.Objectives: We performed this cross-sectional study to determine if specific blood PFC levels are associated with impaired response inhibition in children. Methods: Blood levels of 11 PFCs were measured in children (N = 83) and 6 PFCs: perfluorooctane sulfonate (PFOS), perfluorohexane sulfate (PFHxS), perfluorooctanoic acid (PFOA), …

Prefrontal Cortex Deactivation In Macaques Alters Activity In The Superior Colliculus And Impairs Voluntary Control Of Saccades, Michael J. Koval, Stephen G. Lombar, Stefan Everling

Brain and Mind Institute Researchers' Publications

The cognitive control of action requires both the suppression of automatic responses to sudden stimuli and the generation of behavior specified by abstract instructions. Though patient, functional imaging and neurophysiological studies have implicated the dorsolateral prefrontal cortex (dlPFC) in these abilities, the mechanism by which the dlPFC exerts this control remains unknown. Here we examined the functional interaction of the dlPFC with the saccade circuitry by deactivating area 46 of the dlPFC and measuring its effects on the activity of single superior colliculus neurons in monkeys performing a cognitive saccade task. Deactivation of the dlPFC reduced preparatory activity and increased …

The Association Of Religious Coping On Reports Of Low Back Pain And Inflammatory Markers, Jacqueline D. Bougie

Loma Linda University Electronic Theses, Dissertations & Projects

Chronic pain is the most common cause of disability in the United States with depression, anxiety, and stress often occurring co-morbidly. The purpose of the study was to explore how religion may modulate the frequency of back pain, influence inflammatory markers, influence the use of medications, and impact functional ability.

Participants were from the Biological Manifestations of Religion Study (BioMRS; N= 508) and the Psychological Manifestations of Religion Study (PsyMRS; N = 10,988). All participants completed a 20-page questionnaire and BioMRS participants provided blood, salivary, and urine samples, performance tests, and learning tests all collected within 1 week of …

What Do You Expect? : An Investigation Of How Caffeine Expectancies Affect College Students' Cognitive Performances, Katie Alyse Berg

Undergraduate Honors Thesis Collection

Caffeine use is common, but few studies have examined how the expectancies that people hold about caffeine relate to the effects they experience after consuming it. My study examined how typical caffeine consumption and students' expectancies about how caffeine generally affects them influence their decisions about caffeine use as well as their performance on memory and attention tests. I hypothesized that expectations about how caffeine affects students would interact with their beliefs about how much caffeine they had consumed to impact performance on tests of attention and memory. Undergraduate students were divided into four groups: high consumption and high expectancy, …

Positive Affect During Goal Adoption : Why Happiness Breeds Success, Katherine Wainwright

Undergraduate Honors Thesis Collection

Prior research has shown that positive affect helps individuals to achieve their goals. typically by energizing individuals' performance during goal pursuit. However, questions remain as to whether other mechanisms might exist by which positive affect could facilitate success. Specifically, researchers have yet to address the role that positive affect might play during the process of goal adoption. In the current study, I examined whether positive affect experienced at the time of goal adoption facilitates goal achievement. Participants were induced into either a positive or neutral affective state by watching a video clip. They were also asked to adopt the goal …

The Effects Of A Brief Mindfulness Intervention On Impulsivity In College Students, Myles Elgin Trapp

Undergraduate Honors Thesis Collection

This study investigated the impact of a brief, introductory mindfulness intervention on attention, executive control, and impulsivity. I randomly assigned forty-seven undergraduate students to a treatment group (TG) receiving mindfulness training and a waiting list control group (WLG). Participants completed a battery of self-report questionnaires and standardized neuropsychological tests before and after the intervention. Participants high in trait mindfulness suffered less interference on a Stroop task, were less impulsive on the Balloon Analogue Risk Task, but also evidenced less cognitive flexibility on a dual fluency test at baseline. The TG demonstrated greater improvement than the WLG from baseline to re-test …

The Effect Of Dopamine Therapy On Ventral And Dorsal Striatum-Mediated Cognition In Parkinson's Disease: Support From Functional Mri., Penny A Macdonald, Alex A Macdonald, Ken N Seergobin, Ruzbeh Tamjeedi, Hooman Ganjavi, Jean-Sebastien Provost, Oury Monchi

Brain and Mind Institute Researchers' Publications

The central aim of our study was to elucidate functions mediated by the ventral and dorsal striatum, respectively, to better understand the cognitive effects of dopamine replacement in Parkinson's disease. We proposed that the ventral striatum underlies general learning of stimulus associations, whereas the dorsal striatum promotes integration of various influences on selecting. In Parkinson's disease, dopamine depletion is substantially less notable in the ventral relative to the dorsal striatum, and therefore greater improvements are expected for dorsal striatum-mediated functions with dopamine replacement. Using a simple selection task, we found that dopamine replacement impaired encoding and facilitation of consistent stimulus-stimulus …

College Student Mental Health: The Relationship Between Depression And Emotional Intelligence Using The Student Relationships Assessment, Andre George Broquard

Graduate Theses and Dissertations

The purpose for conducting this study was to investigate the relationship between emotional relational intelligence (ERQ) and depression in college students. The significance of this study is based on the additional support that can be provided to students with increased information and understanding of emotional relational intelligence and depression. In an effort to help college students achieve their educational goals and aspirations, the researcher suggests that emotional relational intelligence can be beneficial. The relationship between depression and emotional relational intelligence may provide insight on how to support and care for college students who are struggling with depressive symptomology. The results …
