Rethinking Attention Control: An Individual Differences Approach, Vincent A. Medina

LSU Doctoral Dissertations

While there is extensive literature on visual spatial attention, less is known about auditory spatial attention, especially in terms of attention control. There is also a growing literature highlighting the importance of considering individual differences in attention control ability. Given these points, the purpose of this study was twofold. The first was to understand how auditory attention control is influenced by spatial location as well as vision. The second was to examine whether individual differences in attention control ability can predict task performance in that context. We utilized two tasks for these purposes. Experiment 1a consisted of a cross-modal Stroop …

Further Refinement Of An Asd-Subscale For The Childhood Behavior Checklist, Kimberly Ellison

LSU Doctoral Dissertations

The early diagnosis of autism spectrum disorder (ASD) is tied to receiving the earliest possible intervention services that can influence a child’s development (Filipek et al., 1999). There are different measurement tools utilized to aid in the diagnostic assessment process, including broadband behavioral rating scales. The Childhood Behavior Checklist (CBCL; Achenbach & Rescorla, 2001) is a parent/caregiver completed questionnaire about one’s child (typically or atypically developing). The CBCL is one of the most utilized broadband measures at the initial stages of a diagnostic assessment or screening to aid in understanding the symptom presentation (Hyman et al., 2020). Currently, there …

Pathways To Blunted Facial Affect In Negative Schizotypy: Social Motivation And Online Cognitive Resources, Tovah M.D. Cowan

LSU Doctoral Dissertations

Schizotypy, a range of personality traits which confer liability for schizophrenia, is associated with significantly diminished social functioning and quality of life. Social dysfunction in all forms of schizotypy, including schizophrenia, is connected to blunted affect, or diminished expressivity, particularly facial expressions which are less frequent, intense, or long than typical. However, the mechanisms and treatments for blunted affect are, as yet, poorly understood and underdeveloped. In this project, two putative mechanisms of blunted affect were explored. The first involves cognitive load capacities, which are diminished in schizotypy, causing blunted affect – individuals do not have the cognitive resources to …

A Comparison Of Self-Report Measures To Screen For Mental Health Concerns In Youth, Jacob Landon Deboer

LSU Doctoral Dissertations

Proactive screening for treatable conditions is not a new concept. Instead, screening has been present in the United States since at least the early 1900s. Accordingly, many schools actively screen for academic problems, yet the same attention is not paid to mental health. Past research estimates that one out of five children in the U.S. has a mental health disorder. However, recent research conducted during the COVID-19 pandemic has found these numbers to be increasing. Additional estimates suggest that only one-third of children with a mental health disorder receive treatment. Schools have a role to play in addressing the identification …

Confirmatory Factor Analysis Of The Adult Coping Inventory, Kristen Ashley Hollas

LSU Doctoral Dissertations

There are few psychometrically sound measures that assess coping in adults. For example, a widely used measure of coping, the COPE, has highly unstable sub-scales and was developed using a homogenous sample (Lyne & Roger, 2000). Because of these limitations, the Adult Coping Inventory (ACI) was developed. The ACI is a 57-item measure that contains five factors including Problem Solving, Mindfulness, Maladaptive Coping, Social Support and Avoidance. Initial reliability and validity analyses demonstrate good construct, concurrent and incremental validity. The current study involved conducting a confirmatory factor analysis to confirm the factor structure of the ACI. The participant sample consisted …

An Evaluation Of Procedures To Increase Medical Device Compliance, Sarah Christian Holmes

LSU Doctoral Dissertations

Behavioral interventions have been implemented to increase compliance with medical devices across patient populations and target devices. Intervention to increase medical device compliance (MDC) can involve a variety of components, including different reinforcement, graduated exposure, extinction, and punishment with varying degrees of acceptability and feasibility. In the current study, we compared the effects of noncontingent (NCR) versus synchronous reinforcement schedules on the duration of MDC and latency to device removal with KN95 face masks with 2 patients with Autism Spectrum Disorder. Following an initial baseline phase demonstrating that both participants engaged in compliance for less than 5 min, we used …

The Psychological Impact Of Adolescent Violence Exposure: The Roles Of Coping And Social Support, Kelsey Gnade Coulthard

LSU Doctoral Dissertations

Research demonstrates that children and adolescents experience a wide range of exposure to violence with rates ranging from 20% and 50% (Finkelhor & Dziuba-Leatherman, 1994; Finkelhor et al., 2005; Zimmerman & Posick, 2016). Violence exposure has been associated with several negative outcomes including biological, psychological, family-based, and academic problems. Further, studies have examined potential protective factors that may buffer against these consequences, with inconsistent results surrounding the roles of coping and social support. However, many of these studies use either an overly generalized definition of both violence exposure and/or social support or use very specific type of violence within a …

Sucrose Demand And Essential Value In Mice With Early-Life Exposure To Risperidone, Megan Federoff

LSU Master's Theses

Second-generation antipsychotics (SGAs), such as risperidone, are widely prescribed to children, but the long-term effects of SGA treatment are not well understood. This study investigated the impact of early-life risperidone treatment on sucrose demand in mice in adulthood. Mice were administered risperidone or vehicle from postnatal day (PND) 33 to 60 and trained in adulthood (>PND 120) to nose poke for a sucrose solution reinforcer. The fixed ratio (FR) value (the number of responses required to produce sucrose delivery; the “price” of sucrose) was varied from 1 to 45, and the resulting consumption versus FR value data were analyzed …

Universal Screening For Student Mental Health: Selection Of Norming Sample As A Determinate Of Risk Status, Meagan Zeitvogel

LSU Master's Theses

The prevalence of student mental health concerns has increased the need for universal mental health screening. In turn, students may have increased access to services and support. Some screeners determine risk status by comparing student scores to norming samples that can be based solely on age (i.e., combined-gender) or on age and gender (i.e., separate-gender). Combined-gender norming samples assign risk status based on typical emotional and behavioral functioning across development. Separate-gender norming samples assign risk status based on developmental and biological differences between boys and girls. Currently, there is no research determining if students’ risk status changes based on norming …

Division I Softball Athletes' Perceptions On Stress, Coping, Performance, And Mental Health, Rhianna Weall

LSU Master's Theses

Collegiate athletes face numerous stressors in both athletic and academic areas of performance. Their perceptions of situations dictate coping responses and their ability to enact behavior or implement strategies to manage stress levels. This study investigated perceived stress and coping strategies using semi-structured in-person interviews with five current NCAA Division I softball players. Three main themes emerged from the interviews: (a) Pressure is Privilege, (b) Team Dynamic and Identity Development, (c) Softball-Centrism. In the first theme, pressure is viewed as a positive aspect and as an opportunity to perform in areas of high and low levels of confidence. Within the …

Neurocognitive Models Of Anxious Apprehension And Emotion Regulation: Implications For Working Memory, Paul Spano

LSU Master's Theses

Children and adolescents with internalizing disorders, such as generalized anxiety and major depression, often experience functional impairment across multiple domains that exacerbates psychopathology. Working memory is a cognitive process that has been scrutinized for its ubiquity in daily life, its strong association with academic success, and its susceptibility to interference from internalizing symptoms, such as a depressed mood or anxious apprehension. However, the literature on the relationship between youth internalizing symptoms and working memory span is sparse, and existing research is confounded by a lack of theoretical clarity and, consequently, incomparable procedures. The present study aims to clarify this relationship …

The Influence Of Native Language And Sentence Form On Memory Of Motion Events, Stephanie L. Lopez

LSU Master's Theses

This study utilized four experiments to investigate the extent to which native language influences memory in accordance with linguistic relativity. In Experiment 1, monolingual English speakers and Spanish/English bilinguals were divided into a verbal encoding condition and a verbal suppression encoding condition and watched motion events of low or high physical salience. Participants engaged in a recognition memory task followed by an event memory similarity judgment task. In Experiment 2, native monolingual English speakers were divided into an English-like (or manner-on-verb) description group, a Spanish-like (or path-on-verb) description group, mimicking the language groups of Experiment 1 respectively, and a verbal …

The What And When Of Psychomotor Retardation: A Multimodal Approach, Ole Edvard Granrud

LSU Master's Theses

Psychomotor retardation (PMR) is a diagnostic criterion that reflects a gross slowing of movement, speech, and thought. More so, PMR is a transdiagnostic, pervasive source of impairment and distress that can be observed across disorders, such as Major Depressive Disorder (MDD), Schizophrenia (SZ), and Bipolar Disorder (BD). In clinical settings, PMR is associated with more severe psychopathology and is used to both inform treatment and predict long-term treatment outcomes. However, despite being clinically meaningful, PMR is poorly understood and is often conceptualized as a motor disturbance that happens in isolation from, rather than concurrently with, higher-order cognitive-emotional processes – such …

Health Service Utilization And Conduct Problems: The Role Of Callous-Unemotional Traits And Juvenile Justice System Processing, Julianne Speck

LSU Master's Theses

Previous research indicates that youth with conduct problems, who are overrepresented in the juvenile justice system, are at risk for utilizing a disproportionate amount of health services compared to youth without these problems. The present study investigates self-reported antisocial behavior, juvenile justice system processing type, and callous-unemotional (CU) traits as predictors of health service utilization (medical and mental health service use and out-of-home placement) across adolescence in a sample of justice-involved males from the Crossroads Study. A total of 766 participants provided data at ten appointments over a period of seven years. A series of linear multiple regressions were used …

Beyond Machine Learning: An Fmri Domain Adaptation Model For Multi-Study Integration, Lauryn Michelle Burleigh

LSU Doctoral Dissertations

Traditional machine learning analyses are challenging with functional magnetic
resonance imaging (fMRI) data, not only because of the amount of data that needs to be
collected, adding a particular challenge for human fMRI research, but also due to the change in
hypothesis being addressed with various analytical techniques. Domain adaptation is a type of
transfer learning, a step beyond machine learning which allows for multiple related, but not
identical, data to contribute to a model, can be beneficial to overcome the limitation of data
needed but may address different hypothesis questions than anticipated given the analysis
computation. This dissertation assesses …

Framing Addiction: How Variations Of News Stories Affect Attitudes Toward Addicts, James A. Smith

LSU Master's Theses

Stigma toward drug addicts and alcoholics can act as a barrier to treatment and, ultimately, result in more lives lost. Over previous decades, journalists have largely framed addicts as problematic to society which contributes to public stigma. Prior research in social medicine has found that non-news portrayals of treated addicts can improve public attitudes. Similarly, studies in mass communication have found that different ways of framing news stories can elicit different attitudes from news consumers. The purpose of this study is to test the effects of thematic framing, episodic framing, problem framing, and solution framing on readers’ attitudes when journalists …

Extending Token Economy Systems For Children With Learning Disabilities And Developmental Disabilities Using Operant Behavioral Economics, Parker Levins

LSU Master's Theses

Token economy systems have been used successfully in various general and special education classrooms. Although effective, educators seldom have a priori information on the performance of their reinforcers within the schedules of reinforcement that comprise the token economy. Most token economies are initially designed based on clinical judgment and respective schedules are typically selected on an arbitrary basis (e.g., token-production Fixed Ratio 1 [FR1], exchange-production FR5). This introduces uncertainty whereby the initial arrangement may be too lax (i.e., work expectations are low for the student) or too strict (i.e., work expectations are high for the student), which both have the …

Evaluating Sensory Quality, Willingness To Try, Risk And Product Appropriateness Of Seafood Byproducts, Silvia Jessenia Murillo Miguez

LSU Master's Theses

Valorization of food wastes/byproducts has become a major subject of research to increase sustainability of the global food supply chain. Seafood industries generate a substantial quantity of byproducts. An online survey was used to evaluate Willingness-to-try (WTT), the effect of a Consumer Safety Statement (CSS) on WTT, perceived risks and product appropriateness associated with seafood byproducts in food as influenced by gender and race. Based on the finding from this survey, a clean label catfish bone powder (CBP) was developed and used for breaded catfish sticks which were evaluated for sensory liking, emotional profile, and purchase intent. Previous consumers of …

Effects Of Neighborhood Disadvantage And Peer Deviance On Conduct Problems: Interactions With Age Of Onset, Courtney Marie Goetz

LSU Master's Theses

Youth with conduct problems (CP) generally fall into two developmental classifications, child-onset and adolescent-onset, which exhibit different causal processes and life course trajectories. Research suggests that child-onset CP is more likely to be related to individual predispositions, while adolescent-onset CP is more associated with social factors, such as peer delinquency. Living in impoverished and disorganized neighborhoods increases the risk for associating with deviant peers. Thus, the current study tested the hypothesis that neighborhood factors would be more strongly associated with adolescent-onset CP than child-onset CP, which would be explained by a greater association with deviant peers. Linear and negative binomial …

Finding Forensic Evidence In The Operating System's Graphical User Interface, Edward X. Wilson Mr.

LSU Master's Theses

A branch of cyber security known as memory forensics focuses on extracting meaningful evidence from system memory. This analysis is often referred to as volatile memory analysis, and is generally performed on memory captures acquired from target systems. Inside of a memory capture is the complete state of a system under investigation, including the contents of currently running as well as previously executed applications. Analysis of this data can reveal a significant amount of activity that occurred on a system since the last reboot. For this research, the Windows operating system is targeted. In particular, the graphical user interface component …

“By That Daughter’S Most Devoted Affection”: Anxious And Avoidant Attachments In Opie’S Adeline Mowbray, Meghan E. Hodges

Comparative Woman

Attachment theory, or the theory that one’s personality and social development is informed greatly by the infant-parent bond, largely arises in the 1950s with the work of John Bowlby. Although the phenomenon was only then beginning to be scientifically evaluated, it has long been observed that the relationship one has with one’s parents is a determinant factor in one’s development. This work investigates the impact of the failure to heal the insecure attachment Amelie Opie’s Adeline Mowbray (1808). Adeline, having grown up in her distant mother’s intellectual shadow, develops a neurotic attachment to her mother which causes romantic maladjustment in …

Wooing “Willing Dupes”: The Bush Administration’S Use Of Emotional Language In The Drive Toward War With Iraq, Michael F. Russo

Faculty Publications

The publicly available texts of the George W. Bush administration from September 11, 2001, to March 19, 2003, as presented in The Public Papers of the Presidents of the United States, were analyzed for word frequency and the words themselves analyzed for emotional weight using the NRC Emotion Intensity Lexicon. Transcripts of six television news agencies (ABC, CBS, NBC, CNN, FOX, and PBS) were also analyzed for word frequency to determine the extent to which these agencies may have repeated and consequently amplified the rhetoric of the administration. Public opinion polling for this same period was examined in an …

Investigating The Relational Element Of Trust In Teacher-Principal Relationships: An Autoethnographic Case Study, Angela Bradley

LSU Doctoral Dissertations

This autoethnographic case study was designed to investigate the relational aspect of trust, a characteristic of servant leadership, in the teacher-principal relationship. This trusting bond is an often overlooked, foundational element of a school’s success. I examined the role that trust plays in enhancing a school’s culture and how trust is established and maintained among one principal and teachers under my supervision. In addition, as researcher, I sought to uncover specific indicators that trust was present on a school campus. Finally, I sought to examine trust’s effects on collaboration and organizational commitment.

Through weekly reflections, I sought to examine my …

Narcissism And Risk-Taking For Others, Tyler B. Cowley

LSU Master's Theses

While prior findings demonstrate that narcissists are excessively risk-seeking for themselves, research does not yet understand if their risk-seeking behaviors extend to others as well. This paper examines the role of narcissism in risk-taking on behalf of others. I hypothesize that narcissists will take more risks when deciding for others because they lack empathy and perspective taking. Therefore, narcissists are more likely to take risks based on their personal preferences, rather than the recipient’s desires. To test my hypotheses, participants completed the Balloon Analogue Risk Task (BART) for themselves, another individual, and an anonymous individual, followed by completing the Narcissistic …

The Impact Of Social Support Sources On Lgbtq Adolescents, Kaitlyn C. Mccauley

LSU Master's Theses

Research demonstrates that adolescents social support plays an important role in protecting against adverse events (e.g., Brewin & MacCarthy, 1989; Muzik et al., 2017). LGBQ adolescents have been shown to experience greater adverse experiences such a daily microaggressions and higher rates of both childhood adversity (Baams, 2018) and peer victimization (Kosciw et al., 2014). Increased stressors often lead to poorer outcomes in this population. Social support research for adolescents has shown that different sources of social support have shown to buffer these reported issues (e.g., greater parent and peer support buffers suicidal ideation, Fredrick et al., 2018). Studies with LGBQ …

Longitudinal Associations Between Housing Instability, Primary Caregiver's Mental Health, Parenting Skills, And Child Behavior Problems: A Latent Growth Modeling Approach, Xi Du

LSU Doctoral Dissertations

Children who grow up in disruptive environments have heightened vulnerability to psychological and behavioral difficulties, which may influence overall well-being through the course of their lives. This study combined a life course perspective with Conger’s family stress model to investigate the longitudinal associations between housing instability, primary caregiver’s mental health, parenting skills, and child internalizing/externalizing behavior problems by unpacking dynamic change from a focal child’s early childhood to adolescence in each factor.

Data came from the Panel Study of Income Dynamics and its Child Development Supplement survey. The analytic sample comprises 783 children who aged 3-7 at enrollment with consistent …

Examination Of Autism Symptoms Across Ethnic Groups: Cross-Cultural Validation Of The Baby And Infant Screen For Children With Autism Traits (Biscuit), Esther Hong

LSU Doctoral Dissertations

Autism spectrum disorder (ASD) a neurodevelopmental disorder characterized by impairments in social communication and interaction and the presence of restricted and repetitive behaviors (American Psychiatric Association, 2013). Variations in prevalence across different racial and ethnic groups have been reported. Though the reason for these variations is unclear, racial and ethnic disparities in access to early screening services, cultural differences in ASD presentation, and the use of culturally insensitive screening tools appear to contribute to disparities in ASD diagnosis. Thus, cultural validation studies of ASD screening tools are needed to investigate the cultural utility of these instruments for use with diverse …

Baseline Differences In Driving Frequency As A Predictor Of Cognitive Decline, Luke R. Miller

LSU Master's Theses

Driving is a complex task heavily dependent on cognitive functions which can decline with age including executive functions and processing speed. Although driving cessation as a predictor of cognitive changes has been studied, driving frequency is understudied in the literature. Thus, the objective of the current study is to evaluate the predictive utility of driving frequency at baseline toward objective cognitive decline beyond other factors associated with cognitive decline (e.g., depression, general functional mobility). The sample included a subset of 1,426 older adults (M age = 77.6, SD = 7.1) from the Rush University Memory and Aging Project. Participants completed …

Development And Validation Of A Measure For Social Support: Perceived Social Support Inventory, Lindsay Marie Clark

LSU Doctoral Dissertations

Abstract

The literature consistently acknowledges the protective function of social support against various negative psychological and physiological outcomes (Cohen & Wills, 1985; Dunst et al., 1986; Taylor, 2011; Uchino, 2009). Further, social support can emerge from different members that comprise an individual’s social network, such as friends, family, teachers, colleagues, and members of common interest groups. Given the important role that social support plays in health outcomes, the importance of psychometrically sound measures for assessing the construct is essential for use in research and clinical settings. However, many of the current measures of social support are outdated, are limited in …
