Reinforcement Learning In Individuals At Risk For Alzheimer's Disease, Christina Marie Figueroa

Master's Theses (2009 -)

Explicit memory is the hallmark of impairment in Alzheimer’s disease (AD) while implicit memory has mixed task-dependent results. Models of memory processes have posited that hippocampal function is sensitive to reinforcement learning (RL), which involves both explicit and implicit memory. The hippocampus is also vital for the transfer of learned associations to novel situations. Nevertheless, RL paradigms have been underutilized in assessing memory processes in individuals at risk for AD, which may aid in early identification of cognitive decline. Thirty-six apolipoprotein-E (APOE) genotyped older adults (Male n=8; Mage=80; Meducation=15 years) performed word stem completion, word recognition, and RL tasks. The …

Understanding African American Male Inmates’ Decisions To Seek Mental Health Treatment While Incarcerated, Darnell A. Durrah Jr.

Dissertations (1934 -)

Incarceration in United States correctional facilities has significantly increased in the past decade (The Pew Charitable Trust, 2009). African American adult males are more likely to be incarcerated compared to all other major ethnic groups (U.S. Department of Justice, 2010). One of the current challenges experienced within correctional facilities is the need to provide appropriate mental health treatment services (U.S. Department of Justice, 2011). Studies have noted the need for such services, however, African American adult males generally are not likely to utilize these services (Morgan et al., 2004). In the general (not incarcerated) population, research has found that cultural …

The Influence Of Anger On Implicit Biases, Katherine Reiter

Master's Theses (2009 -)

Interpretation of ambiguous information is influenced by anxious (Richards, Reynolds, & French, 1992) and depressive (Wisco, & Nolen-Hoeksema, 2010) symptoms. Emotion regulation strategies, and in particular, cognitive reappraisal has shown to be effective at reducing feelings of distress (Denson, Grisham, & Moulds, 2011). The current study seeks to understand the extent that emotion regulation can influence interpretation bias, thoughts and behaviors. In the current study, participants underwent both Angry and Neutral mood inductions. For each mood condition, participants were instructed to cognitively reappraise and attend to their emotions. Participants rated the degree of negative affect they experienced, and completed 6 …

Spiritual Questioning And Its Impact On The Therapeutic Alliance: A Preliminary Study, Cody Carson

Dissertations (1934 -)

A growing number of studies have found that clients would prefer to discuss spiritual and religious (S/R) concerns in psychotherapy and, notably, see it as an appropriate place to discuss these concerns. Although clients report they would prefer to discuss S/R matters with their therapist, psychologists are reluctant to do so. Lack of training may be a factor in the reluctance of psychologist to discuss spirituality and religion with their clients. In addition to the research on spirituality/religion and psychotherapy, the therapeutic alliance has been proposed as a similar component among all forms of treatment and consistently shown to be …

Revising The Body Esteem Scale For The Next Quarter Century, Katherine Frost

Dissertations (1934 -)

Recently, Frost, Franzoi and Oswald (2012) found evidence suggesting that the way individuals evaluate their physical selves, also called body esteem, may have changed over the past quarter century. The findings were particularly strong regarding men's self-evaluations. Because Frost et al.'s (2012) findings focused on the Body Esteem Scale (BES: Franzoi & Shields, 1984), which is a measure that captures dimensions uniquely important to adult self-perception and physical evaluation within a multidimensional and gender-specific framework, one obvious implication of this study is that the BES may need revising in order to remain as current and relevant as possible.

Supervisees' Experiences Of Ruptures In Multicultural Supervision: A Qualitative Study, Laura Lubbers

Dissertations (1934 -)

As the paradigmatic shift of multiculturalism emerges in counseling, the constructs of culture and context warrant examination in the supervision process. With an understanding that conflict is inevitable in supervision relationships particularly when cultural topics are being discussed, investigation into the process of ruptures and rupture repair as they take place within multicultural supervision is warranted. Despite the attention paid to addressing culture in supervision, surprisingly little empirical attention has focused on supervisee experiences of ruptures in multicultural supervision. This study sought to provide a deeper understanding of supervisees' experiences of ruptures in multicultural supervision. Twelve participants were interviewed regarding …

Treating Family Members: The Effectiveness Of A Family-Oriented Dialectical Behavior Therapy Program, Melissa Lynn Miller

Dissertations (1934 -)

Borderline Personality Disorder (BPD) is a severe emotion regulation disorder that, according to the biosocial theory, is developed and maintained through transactions that occur between biologically vulnerable persons and their environment. The family members of persons with BPD may experience many deleterious consequences as a result of their relative's illness, including both objective and subjective forms of burden. Dialectical Behavior Therapy (DBT) was originally developed as a comprehensive treatment for persons with BPD, and new programs designed specifically to treat family members are emerging. These programs aim to help family members cope with their own stressors, as well as help …

Freesurfer Vs. Manual Tracing: Detecting Future Cognitive Decline In Healthy Older Adults At-Risk For Alzheimer's Disease, Alissa Butts

Dissertations (1934 -)

Alzheimer's disease (AD) is a neurodegenerative pathological process that is thought to begin years prior to observable symptom onset. The hippocampus appears to be particularly vulnerable to the underlying brain pathology of AD. Hippocampal volume is a sensitive measure in predicting conversion from mild cognitive impairment to AD, but less is known regarding the use of hippocampal volume in asymptomatic individuals at risk for AD who eventually decline. The inconsistent findings may, in part, be due to the chosen method of hippocampal segmentation. FreeSurfer (FS) and manual tracings (MT) are two common segmentation techniques that have unique costs and benefits. …

An Examination Of The Role Of Neurocognitive Functioning In Illness Management Among Adolescents With Type 1 Diabetes, Christopher James Fitzgerald

Dissertations (1934 -)

Children and adolescents living with Type 1 Diabetes Mellitus (T1DM) face many challenges in their daily lives due to the extensive care tasks that the illness requires. Adolescence is a period of development in which treatment adherence and metabolic control has been found to greatly decline. Research examining correlates of this decline in self-management has tended to focus on familial and psychosocial variables such as parental involvement and T1DM-related conflict. The period of adolescence is also marked by several changes in the development of the frontal lobes and prefrontal cortex, which are areas of the brain that are central to …

Parent Attributional Style And Early Termination From Child And Parent Therapy, Ryan James Mattek

Dissertations (1934 -)

ABSTRACT

PARENT ATTRIBUTIONAL STYLE AND EARLY TERMINATION

FROM CHILD AND PARENT THERAPY

Ryan J. Mattek, M.A.

Marquette University, 2013

Behavior problems are prevalent in young children and represent a threat to a child's typical development. These early behavior problems are even more common in children from low-income, urban settings. If left untreated, such challenging behaviors may become ingrained and lead to later more severe behaviors including aggression, violence, and anti-social behaviors. Research has demonstrated that participation in child and parent therapy (CPT) programs significantly reduces problematic child behaviors while increasing positive behaviors in both the child and the parent. However, …

Neural Correlates Of The Extreme Male Brain Theory In Adolescents With And Without Autism Spectrum Disorders, Audrey Meyer Carson

Dissertations (1934 -)

The Extreme Male Brain (EMB) theory (Baron-Cohen, 2003) is a behavioral theory of autism spectrum disorders (ASD), suggesting that the triad of behavioral impairments in ASD can be conceptualized psychologically as impairment in empathizing, coupled with a superior capacity for systemizing. Despite studies of the behavioral manifestations of this theory, it lacks neurological findings, specifically evidence of less coordinated activity between the left and right hemisphere in ASD (i.e. more lateralized activity). This study attempted to investigate neural correlates of the EMB theory utilizing EEG coherence, an index of neural connectivity, to determine if a more lateralized profile exists in …
