Mood Effects And Individual Differences On Reappraisal And Distraction: An Erp Study Of The Sensitivity Of Emotion Regulation Strategies, Elsa Mastico

All Master's Theses

The present research evaluated the effect of mood and individual differences on the regulatory process of emotions by using a regulation task with negative and neutral images to assess reappraisal and distraction ability. Specifically, this research evaluated the average amplitude of the latent positive potential (latent positivity, LPP) brainwave linked to distraction and reappraisal using an ERP analysis. In addition, the current study compared the modulation of the LPP to the self-reported mood of the participants and their individual differences in regulation ability through scores of a self-report emotion regulation questionnaire. The latent positive potentials from an emotion regulation task …


A Metacognitive Triggering Mechanism For Anticipatory Thinking, Alexander R. Hough, Othalia Larue, Ion Juvina Jan 2020

A Metacognitive Triggering Mechanism For Anticipatory Thinking, Alexander R. Hough, Othalia Larue, Ion Juvina

Psychology Faculty Publications

Current autonomous systems have the ability to adapt to envi-ronmental changes in real-time, but limited ability to engage inanticipatory thinking (AT) with the flexibility to generalize andconsider hypothetical future situations. We argue that metacog-nitive processes are important for an and provide supporting lit-erature primarily from psychology. As an example, we presenta metacognitive monitoring mechanism implemented in a cog-nitive model and discuss ways to extend the mechanism to allowfor dynamic behavior and anticipatory thinking capabilities.


A Natural Remedy: Nbccpt Approach In School For Adhd Diagnosed, Kiran Patel Jan 2020

A Natural Remedy: Nbccpt Approach In School For Adhd Diagnosed, Kiran Patel

Capstone Showcase

Nature-based child centered play therapy (NBCCPT) is a non-directive approach that can be practiced by the counselor in a natural environment consisting of natural tools. The approach allows a child to lead a therapy session without the counselor’s input. Such an approach can be beneficial for children with Attention deficit hyperactivity disorder (ADHD), especially in a school setting. Therapy in school can aid families that cannot afford outpatient therapy as well as allow counselors to track the child’s therapy progress. In school, counselors can utilize an outdoor garden to conduct NBCCPT with the help of five stages, planning, preparing, planting, …


Cancer Patients’ Tobacco Use And Tobacco Treatment Referral Response: Implementation Outcomes At A National Cancer Institute- Designated Cancer Center, Tia Borger Jan 2020

Cancer Patients’ Tobacco Use And Tobacco Treatment Referral Response: Implementation Outcomes At A National Cancer Institute- Designated Cancer Center, Tia Borger

Theses and Dissertations--Psychology

Smoking after cancer diagnosis is linked to cancer-specific and all-cause mortality among other adverse outcomes. Yet, 10-20% of U.S. cancer survivors are current smokers. Implementation of evidence-based tobacco treatment in cancer care facilities is widely recommended, yet rarely accomplished. This study focuses on the early outcomes of a tobacco treatment program integrated within an NCI-designated cancer center. Participants consist of 26,365 patients seen at the cancer center during the first 18 months of implementation. The study is a retrospective chart review of patients’ tobacco use, and among current users, patients’ treatment referral response. Over 99% of patients were screened for …


Mechanisms Of Value-Biased Prioritization In Fast Sensorimotor Decision Making, Kivilcim Afacan-Seref Jan 2020

Mechanisms Of Value-Biased Prioritization In Fast Sensorimotor Decision Making, Kivilcim Afacan-Seref

Dissertations and Theses

In dynamic environments, split-second sensorimotor decisions must be prioritized according to potential payoffs to maximize overall rewards. The impact of relative value on deliberative perceptual judgments has been examined extensively, but relatively little is known about value-biasing mechanisms in the common situation where physical evidence is strong but the time to act is severely limited. This research examines the behavioral and electrophysiological indices of how value biases split-second perceptual decisions and the possible mechanisms underlying the process. In prominent decision models, a noisy but statistically stationary representation of sensory evidence is integrated over time to an action-triggering bound, and value-biases …


Fight, Flight, Or Freezing? Investigating The Immobility Response In Military Veterans, Paige Elizabeth King Jan 2020

Fight, Flight, Or Freezing? Investigating The Immobility Response In Military Veterans, Paige Elizabeth King

UNF Graduate Theses and Dissertations

When the body is faced with threat to life or limb, the autonomic nervous system works to overcome the danger – by either fight, flight, or freezing. While immobility may not appear to be the most logical solution, theories exist that it allows for judgement of the situation and preparation for action. This study investigated the stress response that military veterans, with or without post-traumatic stress disorder (PTSD), demonstrate when shown unpleasant images. Researchers wanted to determine the extent to which veterans would show freezing or immobile responses when under an unpleasant image condition. It was hypothesized that veterans who …


Military Veteran Students Transition To Academic Life With Ptsd, Trauma, And Potential For Freezing Response., Alicia Marie Erchul Jan 2020

Military Veteran Students Transition To Academic Life With Ptsd, Trauma, And Potential For Freezing Response., Alicia Marie Erchul

UNF Graduate Theses and Dissertations

The current study is the first known research to investigate the association of the freezing response with PTSD and traumatic stress in the military veteran student population. Current understanding of the freezing response are primarily based in comparative psychology, with some studies extending to human participants (Azevedo et al., 2005; Facchinetti et al., 2006; Hagenaars et al., 2012; Volchan et al., 2017). Models generally agree that the freezing response consists of reduced body sway with decreased heart rate (Porges, 2003, 2007; Hagenaars et al., 2014).

Thirty-eight military veteran students (n=38; 18 female; 20 male) with ages ranged from 19 to …


An Examination Of Social Connectedness On Ptsd And Freezing In A Student Military Population, Jessica Marie Ledwith Jan 2020

An Examination Of Social Connectedness On Ptsd And Freezing In A Student Military Population, Jessica Marie Ledwith

UNF Graduate Theses and Dissertations

This study investigates the impact of social connectedness (SC) and post-traumatic stress disorder (PTSD) in a military college population, and their relation to physiological measures such as body sway, heart rate (HR), and heat rate variability (HRV). According to previous research, people with PTSD are more likely to exhibit a freezing response to affective images. In the present study, we explore the potential freezing response for military personnel at the levels of PTSD symptom groups and social connectedness. We also investigate the possible buffering effect social connectedness has on the outcome of PTSD and freezing. There was a total of …


Development Of A Multidimensional, Multi-Informent Measure Of Teacher Mindfulness As Experienced And Expressed In The Middle School Classroom, Nicolette P. Rickert, Ellen A. Skinner, Robert W. Roeser Jan 2020

Development Of A Multidimensional, Multi-Informent Measure Of Teacher Mindfulness As Experienced And Expressed In The Middle School Classroom, Nicolette P. Rickert, Ellen A. Skinner, Robert W. Roeser

Psychology: Faculty Publications

In response to growing interest in mindfulness as a support for educators, the current study sought to create and test a new multidimensional and multi-informant measure of teacher mindfulness in the classroom. To counter some of the limitations of context-general self-reports, we designed two theoretically based classroom-specific measures that capture the experience and expression of mindful teacher behavior from the perspective of teachers and students. Drawing on emerging consensus from experts on mindfulness in education, the measures incorporated three dimensions of mindfulness, namely, Calm, Clear, and Kind teacher behavior in the classroom, as well as their antitheses, namely, Reactive, …


Associations Between Stress, Racial Discrimination, And Cytokine Levels In Black Americans, Takia Williams Jan 2020

Associations Between Stress, Racial Discrimination, And Cytokine Levels In Black Americans, Takia Williams

Theses and Dissertations

Inflammation is a common pathophysiological pathway for a number of chronic diseases and is influenced by exposure to stress. Although there are racial disparities in health outcomes, relatively little is known about factors that may influence the inflammatory response in Black American individuals. This study examined whether racial discrimination and other forms of stress are associated with the balance of pro- and anti- inflammatory cytokines in Black American adults. Data from 22 participants were drawn from a larger study of Black American children (ages 5-12) and their primary caregivers drawn from low income neighborhoods in Richmond, Virginia. Caregivers reported demographics, …


Black Women And Body Image: Implications Of The Racialized Beauty Aesthetic, Rachel L. Boutte Jan 2020

Black Women And Body Image: Implications Of The Racialized Beauty Aesthetic, Rachel L. Boutte

Theses and Dissertations

Black women have the highest prevalence of overweight and obesity relative to any other demographic group in the United States, however current weight management interventions appear least effective for them. Although several hypotheses have been proposed to explain these outcomes, few studies have collected data to evaluate how well they fit the lived experiences of Black women. In particular, the potential roles of body image and body dissatisfaction in the development and maintenance of overweight and obesity in Black women are not well understood. Extant literature largely reports that Black women are inoculated from body dissatisfaction due to cultural factors, …

Psychology Faculty Publications

Objective

The present study aimed to determine whether the momentary severity of women's somatic symptoms was concurrently and prospectively associated with their engagement in binge eating in naturalistic settings.

Method

Thirty women (Mage = 34.13, SD = 13.92) who had engaged in binge eating at least once over the month prior to study entry completed a 14-day ecological momentary assessment (EMA) protocol. During each of the 14 days, participants received five semi-random surveys via text message that assessed momentary somatic symptom severity (i.e., headaches, stomachaches/pain, chest/heart pain, faintness/dizziness, shortness of breath, fatigue) and disordered eating behaviors. Generalized estimating equations …


Frontal Brain Injury: Effects On Flexibility, Impulse Control, And Attention, Christopher Matthew O'Hearn Jan 2020

Frontal Brain Injury: Effects On Flexibility, Impulse Control, And Attention, Christopher Matthew O'Hearn

Graduate Theses, Dissertations, and Problem Reports (ETD)

Traumatic Brain Injury (TBI) is defined as an impact to the head, penetration of the skull, or rapid deceleration of the skull, resulting in an alteration of brain function or neurological deficit. Cognitive deficits are common following TBI and often go unresolved due to a lack of effective treatments. These deficits often perseverate into the chronic post injury phase, so the development of rehabilitative strategies is imperative. Behavioral flexibility, impulse control, and attention are a few cognitive processes that are commonly affected by TBI. The current research compares these processes between rats with and without a severe frontal brain injury …

It’s purpose was to gather data that would help to inform future policy decisions aimed at optimizing the use and availability of these services in the KSA. There were three specific aims: 1) Examine the barriers to initiation and continuation of mental health treatment in people with a disorder diagnosed during the previous 12-months. 2) Explore the prevalence and predictors of mental health treatment dropout. 3) Examine the prevalence and patterns …


What Makes An Image Memorable? Effects Of Encoding On The Mechanism Of Recognition, Asiya Gul Jan 2020

What Makes An Image Memorable? Effects Of Encoding On The Mechanism Of Recognition, Asiya Gul

Theses and Dissertations (Comprehensive)

Memory is undoubtedly one of the most important processes of human cognition. A long line of research suggests that recognition relies on the assessment of two explicit memory phenomena: familiarity and recollection. Researchers who support the Dual Process Signal Detection (DPSD) model of recognition memory link the FN400 component (a negative ERP deflection peaking around 400 ms at frontal electrodes) with familiarity; however, it is currently unclear whether the FN400 reflects familiarity or implicit memory. Three event-related potentials (ERP) studies were conducted to determine whether implicit memory plays a role in setting up encoding strategies, and how these encoding strategies …


Retrieval-Induced Forgetting In Autism Spectrum: Combining Narrative Experience With Clinical Research To Explore Stress-Induced, Transitory Retrograde Amnesia, Elizabeth Willsmore-Finkle Jan 2020

Retrieval-Induced Forgetting In Autism Spectrum: Combining Narrative Experience With Clinical Research To Explore Stress-Induced, Transitory Retrograde Amnesia, Elizabeth Willsmore-Finkle

Scripps Senior Theses

Currently, psychological research explores autism, a blanket term for a range of neurobiological and developmental differences, through a clinical, as opposed to an experiential, lens. Autism has only existed as formal diagnosis under that name since 1943 (Kanner); however, the advocacy of activists such as Temple Grandin, a slaughterhouse systems designer best known for documenting her life with autism in a series of autobiographic accounts, has begun to legitimize the incorporation of emic experiences of autism within clinical research. Researcher Dermot Bowler and colleagues (2011) have conducted extensive reviews of memory distinctions in autism, finding differences of varying degrees across …

The Role Of Awareness In Traumatic Brain Injuries: Interviews With Experts, Dominique Chao Jan 2020

The Role Of Awareness In Traumatic Brain Injuries: Interviews With Experts, Dominique Chao

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Approximately 2.8 million US citizens sustain a traumatic brain injury (TBI) annually, with more than 275,000 requiring inpatient rehabilitation (Taylor, Bell & Breiding, 2013). As rehabilitation techniques are refined and adapted to increase the speed of recovery and functional independence following TBIs, there is an ongoing need for better prognostic assessment tools. Research has shown that a lack of self-awareness following TBI is associated with poorer outcomes (e.g. employability, community reintegration) following discharge from inpatient hospitalizations (Cheng & Man, 2006; Robertson & Schmitter, 2016) and can result in decreased motivation (Simmonds & Fleming, 2003), compromised safety, poor community re-integration, and …


A Five-Sample Confirmatory Factor Analytic Study Of Burnout-Depression Overlap, Renzo Bianchi, Irvin Sam Schonfeld, Jay Verkuilen Jan 2020

A Five-Sample Confirmatory Factor Analytic Study Of Burnout-Depression Overlap, Renzo Bianchi, Irvin Sam Schonfeld, Jay Verkuilen

Publications and Research

Objective: It has been asserted that burnout—a condition ascribed to unresolvable job stress—should not be mistaken for a depressive syndrome. In this confirmatory factor analytic study, the validity of this assertion was examined.

Methods: Five samples of employed individuals, recruited in Switzerland and France, were mobilized for this study (N = 3,113). Burnout symptoms were assessed with the Shirom–Melamed Burnout Measure, the Maslach Burnout Inventory (MBI)—General Survey, and the MBI for Educators. Depressive symptoms were measured with the PHQ‐9.

Results: In all five samples, the latent factors pertaining to burnout’s components correlated on average more highly with the latent Depression …

Mental Illness Stigma’S Impact On Perceptions Of Intimate Partner Violence Victims: A Mock Juror Study, Madeline K. Butters Dec 2019

Mental Illness Stigma’S Impact On Perceptions Of Intimate Partner Violence Victims: A Mock Juror Study, Madeline K. Butters

Honors Program Theses and Projects

Intimate partner violence (IPV) is a widespread issue that disproportionately affects women with mental illness. Yet, there is a lack of research on the effects of mental illness stigma on legal perceptions of women with mental illness in IPV cases. The present study experimentally investigated mock jurors’ perceptions of IPV cases where the victim has a mental illness and examined the role stigmatization of mental illness played in these perceptions. MTurk participants (N = 191) first completed attitude questionnaires that measured their attitudes towards mental illness and their beliefs about domestic violence. In the second part of the study, participants …

Human Adaptability For Deep Space Missions: An Exploratory Study, Paul T. Bartone, Robert R. Roland, Jocelyn V. Bartone, Gerald P. Krueger, Albert A. Sciarretta, Bjorn Helge Johnsen

Journal of Human Performance in Extreme Environments

The present qualitative study conducts in-depth interviews with astronauts and other subject matter experts in order to shed light on human adaptability in extreme environments. Deep space travel will entail a range of highly stressful conditions to which astronauts must adapt. Feelings of isolation will be increased, as the space traveler is farther from Earth for longer periods of time. Daily life will take place in small and confined areas, for durations extending into years. The dangers of the extreme environment of space are ever-present, and failure of critical equipment or components can lead to death. Astronauts will need to …


Human Milk Omega-3 Fatty Acid Composition Is Associated With Infant Temperament, Jennifer Hahn-Holbrook, Adi Fish, Laura M. Glynn Dec 2019

Human Milk Omega-3 Fatty Acid Composition Is Associated With Infant Temperament, Jennifer Hahn-Holbrook, Adi Fish, Laura M. Glynn

Psychology Faculty Articles and Research

There is growing evidence that omega-3 (n-3) polyunsaturated fatty-acids (PUFAs) are important for the brain development in childhood and are necessary for an optimal health in adults. However, there have been no studies examining how the n-3 PUFA composition of human milk influences infant behavior or temperament. To fill this knowledge gap, 52 breastfeeding mothers provided milk samples at 3 months postpartum and completed the Infant Behavior Questionnaire (IBQ-R), a widely used parent-report measure of infant temperament. Milk was assessed for n-3 PUFAs and omega-6 (n-6) PUFAs using gas-liquid chromatography. The total fat and the ratio of n6/n-3 fatty acids …


The Healing Power Of The Arts - Drama Therapy And The Use Of Theatre In The Treatment Of Trauma, Brooklyn Snyder Dec 2019

The Healing Power Of The Arts - Drama Therapy And The Use Of Theatre In The Treatment Of Trauma, Brooklyn Snyder

Student Scholar Symposium Abstracts and Posters

Theatre is an incredibly valuable therapeutic tool. In this thesis, I explore the ways in which trauma can reshape individuals lives, both cognitively and physically, impeding their sense of self, ability to trust, engagement, and many other seemingly ordinary aspects of day to day life that those of us unaffected by trauma take for granted. Additionally, I cover how employing theatrical tools, like improvisation and role play, can act as a beneficial treatment option for those who have suffered a traumatic past. Drama therapy allows individuals to reconnect with their bodies and their minds, gain new perspectives on their experiences, …


Influences Of Reasoning And Achievement Motivation On Complex Problem Solving In A New Microworld Operationalization, Stephan Bartholdy, Ulrike Kipman Dec 2019

Influences Of Reasoning And Achievement Motivation On Complex Problem Solving In A New Microworld Operationalization, Stephan Bartholdy, Ulrike Kipman

Journal of Global Education and Research

Complex Problem Solving (CPS) can be defined as those psychological processes that enable a person to achieve goals under complex conditions, which are characterized by their complexity, connectivity, dynamics, lack of transparency, and polytely. Although many hypothesized influences have previously been tested concerning their relevance for the process of solving complex problems (e.g., general intelligence), results were often found to be rather heterogeneous. As this was found to be partially caused by fundamental differences between measurements of CPS, a new operationalization was used in the present study: Following the Microworld approach, CPS was assessed in the simulation game Cities: Skylines …


Turn That Frown Upside-Down! The Effectiveness Of Opposite Action In Changing Emotion, Kaitlyn Diane Chamberlain Dec 2019

Turn That Frown Upside-Down! The Effectiveness Of Opposite Action In Changing Emotion, Kaitlyn Diane Chamberlain

Graduate Theses and Dissertations

While research demonstrates that opposite action (OA) impacts emotion (Rizvi & Linehan, 2005), we lack an understanding of the mechanisms by which it produces opposite emotions. The current study dismantled emotion regulation skill components by comparing tasks with different combinations of cognitive, emotive and behavioral components. I predicted that the OA condition would be the most effective in altering negative emotion. University students (n = 194) completed a sadness induction and were randomly assigned to either a (1) control, (2) low arousal positive imagery (3) high arousal positive imagery, or (4) OA plus high arousal positive imagery condition. The control …


Social Anxiety Reduction In The Context Of Social Modeling Utilizing A Placebo Alcohol Beverage, Kyle K. Jackson Dec 2019

Social Anxiety Reduction In The Context Of Social Modeling Utilizing A Placebo Alcohol Beverage, Kyle K. Jackson

Graduate Theses and Dissertations

Alcohol misuse and elevated social anxiety are found to be highly comorbid, and being exposed to social models consuming alcohol can increase one’s consumption. Yet no research has thus far examined whether the internal experience of alcohol consumption (e.g., social anxiety reduction) can also be transmitted via social modeling. This bar-lab study examined the impact of social modeling behavioral cues of social anxiety on emerging adult drinkers. It was hypothesized that those exposed to a social model experiencing an apparent social anxiety reduction from drinking would themselves report lessened state social anxiety following a placebo drink, and that this effect …


The Role Of Gamma Oscillations And Cortical Inhibition In The Development Of Working Memory In Adolescence, Christopher P. Walker Dec 2019

The Role Of Gamma Oscillations And Cortical Inhibition In The Development Of Working Memory In Adolescence, Christopher P. Walker

Dissertations and Theses (Open Access)

Adolescence is a dynamic period of social, cognitive, and biological changes. In particular, working memory, the ability to actively encode and maintain information over a short period of time, develops early in childhood and gradually increases in capacity and stability during adolescence. The precise neurophysiological mechanism by which working memory capacity increases during adolescence is unclear. The objective of this investigation was to evaluate the role of cortical gamma-band (> 30 Hz) oscillations—which are associated with working memory in adults—for the development of working memory capacity in adolescents, and to identify the extent to which the temporal profile of gamma-aminobutyric …
