Cognitive Impairment, Depression, Anxiety, And Personality And Ms Patient Estimations Of Memory Function, Jordan Charboneau Oct 2017

Cognitive Impairment, Depression, Anxiety, And Personality And Ms Patient Estimations Of Memory Function, Jordan Charboneau

Dissertations (1934 -)

Multiple Sclerosis (MS) is an autoimmune disease of unknown etiology, characterized by a wide range of physical, cognitive, psychological, and behavioral symptoms. To effectively diagnose and treat MS, clinicians rely on patient reports of function to help identify and treat their problems (Kinsinger, Lattie, & Mohr, 2010). Specifically, self-reports of cognitive symptoms are a valuable source of information upon which clinicians depend (Van der Hiele, Spliethoff-Kamminga, Ruimschotel, Middelkoop, & Visser, 2012). While patient reports of cognitive functioning, including memory, are important, there has been substantial debate about the accuracy of such information. The present study investigated the association between general …


An Empirical Examination Of A Well-Being Engine Model, Korey Jacob Connor Oct 2017

An Empirical Examination Of A Well-Being Engine Model, Korey Jacob Connor

Dissertations (1934 -)

Humanity has struggled to define the good life from, at very least, the beginning of recorded history. The last three decades have seen a major uptick in the amount of scholarly activities in this vein, with contemporary iterations falling under the auspices of well-being studies. These studies in the field of psychology, while abundant, have tended to align closely with one of a select few schools of thought while eschewing alternative approaches. Studies are produced at a dizzying rate, but are often limited in scope and in need of greater conceptual clarification. A promising integrative theoretical model, called the engine …


Feature Space Augmentation: Improving Prediction Accuracy Of Classical Problems In Cognitive Science And Computer Vison, Piyush Saxena Oct 2017

Feature Space Augmentation: Improving Prediction Accuracy Of Classical Problems In Cognitive Science And Computer Vison, Piyush Saxena

Dissertations (1934 -)

The prediction accuracy in many classical problems across multiple domains has seen a rise since computational tools such as multi-layer neural nets and complex machine learning algorithms have become widely accessible to the research community. In this research, we take a step back and examine the feature space in two problems from very different domains. We show that novel augmentation to the feature space yields higher performance. Emotion Recognition in Adults from a Control Group: The objective is to quantify the emotional state of an individual at any time using data collected by wearable sensors. We define emotional state as …


Biculturalism, Bilingualism, & Executive Function Among U.S. Latinos: Implications For Cognitive Reserve, Leticia G. Vallejo Oct 2017

Biculturalism, Bilingualism, & Executive Function Among U.S. Latinos: Implications For Cognitive Reserve, Leticia G. Vallejo

Dissertations (1934 -)

The current study was an exploratory investigation of the cultural constructs of biculturalism and bilingualism as predictors of executive function among a community-based sample of 25 older adult Latinos living in the U.S. The potential moderating effects of education and bicultural identity integration were also examined. Using regression analyses, biculturalism and bilingualism were examined independently as predictors of performance on three separate tasks of executive function: trail making tests, a phonemic fluency task, and a clock drawing task. Bilingualism was not found to predict performance on any of the executive functioning tasks. In the overall sample, biculturalism also was not …


Sleep, Internalizing Symptoms, Executive Functioning, And Diabetes Outcomes In Adolescents With Type 1 Diabetes Mellitus, Ashley Charlene Moss Oct 2017

Sleep, Internalizing Symptoms, Executive Functioning, And Diabetes Outcomes In Adolescents With Type 1 Diabetes Mellitus, Ashley Charlene Moss

Dissertations (1934 -)

Insufficient sleep is a nearly universal problem during adolescence and is likely associated with various biopsychosocial and contextual factors present with this developmental period. Youth with type 1 diabetes mellitus (T1DM) may experience greater sleep difficulties, poorer sleep quality, and greater daytime sleepiness/fatigue compared to healthy youth. Also, sleep difficulties are associated with poorer diabetes outcomes (e.g., treatment adherence). Understanding how sleep may impact illness management during adolescence is critical given increasing rates of non-adherence during this developmental period. Although research suggests poor sleep is associated with decreased neurocognitive functioning and increased internalizing behavior among healthy youth, limited research has …


Heart Rate Variability Biofeedback Training As An Intervention For Chronic Pain, Annette Marie Wilson Jul 2017

Heart Rate Variability Biofeedback Training As An Intervention For Chronic Pain, Annette Marie Wilson

Dissertations (1934 -)

Millions of Americans suffer from chronic pain. Treatment costs are in the billions and some patients still do not find relief. Current effectiveness research shows positive results for biofeedback training as an intervention for headache and other types of chronic pain. The present retrospective, archival study used patient information (N=72) collected during a heart rate variability biofeedback training program to assess treatment effectiveness among patients who experience chronic pain. More specifically, the study was designed to examine six research questions focused on patient-reported levels of pain and distress, as well as catastrophizing, depression, anxiety, and somatization. It was hypothesized that …


Examining The Durability Of Peers For Adolescents With Asd: Maintenance Of Neurological And Behavioral Effects, Bridget Kathleen Dolan Jul 2017

Examining The Durability Of Peers For Adolescents With Asd: Maintenance Of Neurological And Behavioral Effects, Bridget Kathleen Dolan

Dissertations (1934 -)

To date, there are no known published studies that have assessed the maintenance of treatment effects in the context of neurological changes and their relationship to behavioral outcomes following a social skills intervention for adolescents with Autism Spectrum Disorder (ASD). The few studies that have incorporated long-term assessment into their design have focused exclusively on sustained behavioral responses to treatment. Individuals with ASD across the lifespan exhibit aberrant neural activity, which is thought to underlie social skill deficits noted in persons on the spectrum. Thus, this study sought to examine the impact of a social skills intervention, the Program for …


Trauma Therapy For Very Young Children Living In Poverty: A Randomized Controlled Trial, Joanna Ruth Love Jul 2017

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

Dissertations (1934 -)

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


Aging, Executive Function, Fronto-Parietal Network Cortical Thickness: Insights From Cognitive Reserve, Katherine Reiter Jul 2017

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

Dissertations (1934 -)

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


Experience Of Nontenured, Tenure-Track Faculty And Gatekeeping: A Qualitative Research Study, Meghan Butler Jul 2017

Experience Of Nontenured, Tenure-Track Faculty And Gatekeeping: A Qualitative Research Study, Meghan Butler

Dissertations (1934 -)

Using a consensual qualitative research (CQR) approach, this study investigated the experience of nontenured, tenure track faculty (NTTTF) members involved in gatekeeping with students for non-academic concerns from American Psychological Association (APA)- and The Council for the Accreditation of Counseling and Related Educational Programs (CACREP)-accredited programs. The study investigated the emotional and cognitive reactions, factors supportive/facilitative and discouraging/hindering of the decision to intervene, the impact the gatekeeping process had on NTTTF relationships and what the NTTTF learned from the gatekeeping intervention. Participants were five female faculty members. Results indicated participants had little to no training in gatekeeping beyond informal training …


The Impact Of Racial Miscategorization And Racial Ambiguity On Multiracial Identity And Well-Being: A Qualitative Study, Shirley A. Newcomb Jul 2017

The Impact Of Racial Miscategorization And Racial Ambiguity On Multiracial Identity And Well-Being: A Qualitative Study, Shirley A. Newcomb

Dissertations (1934 -)

Despite the rapid growth of the multiracial population there is a dearth of literature that informs the field of counseling psychology about the identity development and well-being of multiracial people. More specifically, there is little research which explores the challenge of having one’s racial identity repeatedly questioned and/or miscategorized, and how these experiences of racial miscategorization and racial incongruence may influence their identity choices and well-being. The sample consisted of 11 total participants, (women N = 9, men N = 2) who self-identified as racially ambiguous and of multiracial descent. Overall findings of the study suggest that experiences of racial …


Stress And Prosocial Decision Making: The Influence Of Acute Stress On Trust Behavior, Stephanie Ross Potts Apr 2017

Stress And Prosocial Decision Making: The Influence Of Acute Stress On Trust Behavior, Stephanie Ross Potts

Dissertations (1934 -)

While acute stress exposure has been associated with modulation of risk-taking in decision making, the influence of stress on social decision making and trust has not been well-researched. The current study aims to advance scientific understanding of how stress influences trust behavior. Ninety-six participants (49 male and 47 female) engaged in an adapted Trust Game task, randomly assigned between-subjects to either an acute stress (cold pressor test or socially evaluative cold pressor test) or control group. The Trust Game was administered at different time points with respect to stress exposure to examine the potential differential roles of temporally distinct stress …


Heterosexual Allies' Confrontation Of Sexual Prejudice: The Effect Of Gender, Attitudes, And Past Allied Behavior, Kelly L. Lemaire Apr 2017

Heterosexual Allies' Confrontation Of Sexual Prejudice: The Effect Of Gender, Attitudes, And Past Allied Behavior, Kelly L. Lemaire

Dissertations (1934 -)

Confrontation of prejudice is one method that has been demonstrated to reduce future discrimination on behalf of perpetrators and non-target witnesses in the future. The current study sought to 1) determine whether the gender of the perpetrator, target, or witness of heterosexist prejudice affects witness’s reactions to prejudice, including confrontation, 2) understand if other factors including participants’ attitudes about society, gender roles, and gay men and lesbian women, as well as their general level of assertiveness and previous allied behaviors were predictive of confrontation behavior and 3) examine participant’s satisfaction with their responses and anticipated future responses in relation to …
