Inducing Proactive Control With High Load Ax-Cpt, Mina Selim

Electronic Theses, Projects, and Dissertations

A central hypothesis of cognitive control is that goal maintenance operates via two distinct modes: proactive control and reactive control (Braver, Gray, & Burgess, 2007). Individuals using a proactive strategy, focus on actively maintaining goal-relevant information in memory, whereas reactive individuals store goal-relevant information and retrieve it when cues are present. This theoretical framework for understanding the sources of variation in cognitive control is termed the dual mechanisms of control (DMC). When compared to high working memory capacity (WMC) individuals, low WMC individuals tend to utilize reactive control more often. However, some factors influence an individuals’ bias towards one type …

Posttraumatic Stress Disorder: Comparing Short-Term, Intensive Therapy To Traditional, Long-Term Therapy, Laura Gonzalez, Sean Kruckenberg

Electronic Theses, Projects, and Dissertations

ABSTRACT

Posttraumatic Stress Disorder (PTSD) is a mental health diagnosis that occurs following a traumatic event, and military veterans are at higher risk of exposure to hazardous or life-threatening situations that may result in psychological trauma.

Many agencies, such as the Department of Veteran’s Affairs (VA) provide treatment PTSD, however most programs experience dropout rates as high as 36%. Recent studies have shown that …

Does Working Memory Capacity Modulate The Relationship Between Intentional Mind-Wandering And Task Demand?, Stephen Ware

Electronic Theses, Projects, and Dissertations

Mind wandering (MW) is affected by multiple factors. Among those factors, the present study investigated the effects of working memory capacity on task demands on types of mind wandering. It was hypothesized that individuals with high working memory capacity (WMC) would show more intentional mind wandering in a low demanding task, and in this case, task performance would not be impaired. On the other hand, individuals with low working memory capacity would show more unintentional mind wandering in the high demand condition; therefore, task performance would be affected. Task demand was manipulated with verbal n-back tasks and WMC was measured …

Treatment Access For Dual Diagnosis Substance Use And Mental Health Disorders, Pedro Banuelos

Electronic Theses, Projects, and Dissertations

In 2018, of 1.3 million Latinx adults in the United States facing concurrent issues with substance use disorders (SUD) and mental health disorders (MHD) 93% remained untreated for either diagnosis. This is concerning since Substance Abuse and Mental Health Services Administration (SAMHSA) data reveals that this population is at greater risk for suicidal thoughts, plans, and attempts. They also face structural barriers such as employment, housing, legal involvement, and insurability that further impede access to treatment.

This study’s purpose was to examine barriers to accessing treatment for Latinx populations confronting co-occurring SUDs and MHDs. This study used a qualitative design …
