The Use Of Systematic Distractions To Increase Sustained Attention In School-Aged Children With Attention Problems, Emma Larson

LSU Master's Theses

With the growing prevalence of Attention Deficit Hyperactivity Disorder (ADHD) in children (DSM-5, 2013), it has been established that the ability of these children to sustain attention is marked with difficulty (Barkley, 2006). Prior research has addressed the need to increase sustained attention in children with ADHD, however, not all of the promising methods take into consideration that children with ADHD have difficulty ignoring distractions (Rapport et al., 2009). This is problematic because the typical classroom environment is filled with distractions. The current study attempted to fill this research gap by training participants to sustain attention while systematically introducing distractions …

The (B)Link Between Amotivation And Dopamine In Psychosis: What Phasic Eye Blink Rate Reveals, Jessica Elaina Mcgovern

LSU Doctoral Dissertations

Motivation deficits (i.e., avolition or amotivation) are a cardinal feature of schizophrenia spectrum disorders (SSDs) and are linked to worse functional outcomes. Accumulating evidence implicates underactive dopamine responses in reward areas of the brain (e.g., striatum) in the etiology of amotivation. Phasic dopamine firing in the striatum purportedly has a role in increasing the perceived value of a potential reward that, in effect, helps “push” the organism toward initiating and persisting in the action to pursue rewards. Previous research has suggested that eye blink rate (EBR) may be a reliable and valid index of striatal dopamine. Amotivation (clinician-rated and self-reported) …

A Randomized Controlled Trial Of A Hatha Yoga Intervention For Smokers, Emily Robin Jeffries

LSU Doctoral Dissertations

Despite well-documented negative effects of smoking, many individuals continue to smoke. Anxiety and depression are associated with poorer cessation outcomes. Three transdiagnostic factors may explain the anxiety/depression-smoking link: anxiety sensitivity (AS), distress tolerance (DT), anhedonia (Anh; Leventhal & Zvolensky, 2015). It therefore follows that changing AS, DT, and Anh could aid cessation efforts. Thus, the current study tested the efficacy of hatha yoga for reducing craving, smoking, AS, and Anh and increasing DT, and whether anxiety/depression moderates these relationships. Participants were 55 community-recruited smokers (62% male, 71% non-Hispanic White, M_age = 28.16) motivated to reduce or quit smoking. We …

Predicting Working Memory And Fluid Intelligence From Measures Of Musicality, Juan Alexander Ventura

LSU Master's Theses

The relationship between musicality and cognitive abilities has been a popular topic in the media and among researchers over the last 25 years. Research has been inconsistent on whether musicality influences performance on non-musical complex tasks, such as measures of working memory and fluid intelligence. Inconsistencies regarding results between studies have arisen partly due to differences in sample and task selection, in addition to conflicting interpretations of results. Consequently, we conducted an individual differences investigation on the prediction of working memory (tonal, verbal, and visuospatial) and fluid intelligence by measures of musicality (formal years of musicality training, musical sophistication, melodic …

Attentional Deployment, Cognitive Control, And Reappraisal In Schizophrenia, Kyle Robert Mitchell

LSU Doctoral Dissertations

Recent studies posit that deficits in emotion regulation may lead to increased negative emotional experience in schizophrenia. While individuals with schizophrenia evidence a number of abnormalities in emotion regulation, it is unclear whether these deficits are discrete or related; furthermore, the mechanisms underlying these deficits are not clear. Cognitive control has been posited as an important mechanism supporting emotion regulation. The current study examined the relationship between attentional deployment and both lexical and self-reported indices of reappraisal, as well as the mediating role of cognitive control on this relationship in a sample of 22 individuals with psychotic disorders. A novel …

Differential Effects Of Mindful Breathing And Loving-Kindness Meditation Exercises On College Students' Mental Health, Sarah J. Bolognino

LSU Doctoral Dissertations

Mindfulness and loving-kindness are two concepts with associated meditation exercises that have been evaluated as part of mindfulness-based treatment approaches (MBTAs) to improve mental health. A common MBTA, Mindfulness Based Stress Reduction (MBSR) includes multiple component exercises including mindful breathing meditation (MBM), and loving-kindness meditation (LKM). The purpose of the present study was to examine differential effects of MBM and LKM on the proposed process variables of social connectedness, cognitive fusion and experiential avoidance, present moment awareness, affect, and compassion for self and others, as well as across outcomes measures of general anxiety, social anxiety, depression, and wellbeing. Additionally the …

Examining The Sex Ratio In Autism Spectrum Disorder, Maya N. Matheis

LSU Doctoral Dissertations

The higher prevalence of autism spectrum disorder (ASD) among males compared to females is well documented but poorly understood. The ASD sex ratio may provide valuable insight into the underlying neurobiological mechanisms of the disorder. A review of studies examining the prevalence in ASD published in the last 5 years was conducted, revealing a mean male/female (M/F) ratio of 4. Literature examining the ASD sex ratio in relation to risk factors and associated features of ASD was also summarized. The study aimed to examine the ASD sex ratio and its association to various risk factors among an early intervention sample. …

Focality In Prospective Memory: A Thorough Examination Of Cue Specificity And Task-Appropriateness, Bethany Alice Lyon

LSU Doctoral Dissertations

Prospective memory (PM) refers to memory for future intentions (e.g. remembering to press a button when you see an animal word). Researchers classify PM intentions in the laboratory as focal or nonfocal primarily in two ways. One way, task-appropriateness, refers to how the processing for the intention relates to the processing required for an ongoing task; the PM intention and the ongoing task either match in processing (TAP; focal) or mismatch in processing (TIP; nonfocal). The second way researchers classify focality is based on cue specificity, with the PM task either being specific (focal) or general (nonfocal). Resolving this ambiguity …

The Potential Iatrogenic Effects Of Formal Vs. Informal Juvenile Justice System Processing: The Moderating Influence Of Callous-Unemotional Traits, Emily Lynne Robertson

LSU Master's Theses

Previous research has indicated that adolescents who are formally processed by the juvenile justice system are at a higher risk of worse outcomes, most notably increased risk for subsequent offending and arrests. However, it is unclear whether this effect is due to the processing decision and subsequent involvement with the justice system or whether it is due to characteristics of the adolescents who are formally processed. Further, it is unclear whether formal processing increases the risk for future offending in all adolescents or whether its effects are more pronounced for certain adolescents. In the current study, we tested the predictions …

Evaluating The Predictive Validity Of The Implementation Beliefs Assessment On Classwide Management Components, Sarah Alexa Metallo

LSU Doctoral Dissertations

Given the broad framework of the Positive Behavioral Interventions and Supports model, its barriers to adaptability and implementation in schools have affected an increased emphasis on exploration and measurement of treatment integrity. A tool directly linked with a model of treatment integrity is the Implementation Beliefs Assessment (IBA; Sanetti, Long, Neugebaur, & Kratochwill, 2012). The IBA has preliminary evidence indicating it is a psychometrically sound measure; however, since it is a measure related to behavior change, assessing its predictive validity of treatment integrity is a useful indicator of this tool’s value during the consultation process. The current study utilized multiple …

A Preliminary Examination Of The Time And Organization Preparation System-College (Tops-C) With Undergraduate Students, Ashley Elizabeth Bordelon

LSU Doctoral Dissertations

Many factors contribute to the educational success of undergraduate students, including personal beliefs, effort, and the ability to self-manage. Many students are not prepared for the rigors of post-secondary education. This need is particularly striking given the limited availability of manualized evidenced based interventions available to support college students with academic task demand management. This study sought to determine the efficacy of the Time and Organization Preparation System-College (TOPS-C), a program aimed to increase study skills, organization, self-regulated learning, and time management through direct instruction, group contingency, and performance feedback. To determine changes in skill level, students completed the Learning …

What Motivates Children To Respond? Functional Analysis And Intervention Of Math Computation Fluency, Catherine Rose Lark

LSU Doctoral Dissertations

An abundance of research exists supporting the use of functional analyses to assess and treat problem behavior. In contrast, little research has been conducted on the application of functional analysis (FA) procedures to academic behaviors. The current study attempted to fill this research gap by conducting an FA of academic responding for five elementary students with low math fluency. Sessions were conducted using both a traditional reinforcement schedule of a fixed ratio of one (FR-1) as well as a more practical reinforcement schedule of a fixed ratio of ten (FR-10) to examine the effects of the reinforcement schedule on the …

The Relationship Between Maternal Distress And Adjustment Problems In Adolescents With Attention-Deficit/Hyperactivity Disorder: An Examination Of Family Routines And Communication As Moderators, Ryan Nicole Cummins

LSU Master's Theses

Attention-Deficit/Hyperactivity Disorder (ADHD) is a common disorder in youth. The presence of comorbid internalizing and externalizing symptoms is a frequent occurrence in ADHD youth; comorbid symptoms are associated with poor adjustment into adolescence and negative trajectories into adulthood. There are many contributing factors in the development of comorbid symptoms (e.g., parental distress and family environment). Thus, it is important to understand the relationship between contributing factors and the ways in which family consistency helps to manage problem behaviors in adolescents with ADHD. One way to increase consistency is through the use of routines and positive communication. The present study examined …

Implementation Planning Adapted For Group-Based Training Of Proactive Classroom Management Strategies, James Jaran Upright

LSU Master's Theses

Proactive classroom management (PCM) strategies are preventative teacher practices implemented prior to the onset of problem behavior. PCM strategies have been widely demonstrated to be effective in preventing and reducing disruptive behavior while promoting academic engagement in the classroom. In practice, however, the use of proactive strategies is far less common than reactive strategies for managing student behavior. Although teachers are concerned about classroom management, many report a lack of training or support needed to successfully implement behavior management strategies. One promising approach for supporting teachers’ use of behavior management strategies is implementation planning. Implementation planning is an implementation support …

Is Social Anxiety Related To An Attentional Bias To Suicide?, Austin Warner Lemke

LSU Master's Theses

Suicide is the cause of death of over 800,000 people worldwide each year and is one of the leading causes of death in the U.S. Individuals with elevated social anxiety appear to be at a particularly high risk for suicide. Attentional bias is a maintaining factor in a broad range of psychological conditions including social anxiety, and an attentional bias toward suicide-related cues is related to both past and future suicide attempts. However, little research has been done on attentional biases toward suicide-related cues, and no known research has examined whether individuals with elevated social anxiety have a bias toward …

Identifying Stress Variables Linking Socioeconomic Status And Smoking, Aaron French Waters

LSU Master's Theses

Smoking is the leading cause of preventable death accounting for approximately 480,000 deaths every year (Jamal et al., 2015). Across the socioeconomic status gradient smoking prevalence differs greatly, with those of lower socioeconomic status smoking at much higher rates. Within the literature relationships have been identified between socioeconomic status, stress variables, and smoking. However, little research has explored the possibility of stress variables mediating the relationship between socioeconomic status and smoking. The goal of the current study was to identify stress variables linking socioeconomic status and smoking in order to identify variables to address in cessation programs for …

Development Of The Routines And Time Management Inventory For Young Adults, Morgan Ashwill Grinnell

LSU Doctoral Dissertations

Routines are observable and repetitive behavior patterns that are context specific and help to automate aspects of daily life (Sytsma, Kelley, & Wymer, 2001; Zisberg, Young, Schepp, & Zysberg, 2007). The presence of routines in an individual’s life promotes overall functioning, and irregular routines have been associated with poorer physical and psychological health (Margraf, Lavallee, Zhang, & Schneider, 2016). Time management skills, such as those required to plan, prioritize, and execute tasks are crucial to cultivating stable routines. Although measures of routines exist for children, adolescents, families, and older adults, the routines of younger adults have been neglected.

A Study Of The Lived Experience Of African American Males Who Transition From Out-Of-Home Care To Postsecondary Education, Marvin Cain Alexander

LSU Doctoral Dissertations

While the literature is replete with studies of the factors contributing to the failure and social deviance of African American males, few qualitative studies have been conducted to determine the factors that support the success of African American males, and virtually none have focused on the transition of African American males from out-of-home care to postsecondary educational institutions. Despite the challenges faced preceding and during out-of-home care, African American males can transition to postsecondary educational institutions. There is a need to understand why some African American males who experience out-of-home care can accomplish this while others cannot. It is imperative …

Personalized Normative Feedback For College Student Condom Use, Sonia Mahesh Shah

LSU Doctoral Dissertations

Personalized normative feedback (PNF) interventions provide corrective normative feedback and have been found to successfully elicit behavior change (e.g., related to alcohol consumption, gambling). There are no known PNF interventions that explicitly target risky sexual behavior (RSB). PNF interventions have demonstrated significant reductions on drinking outcomes and normative perceptions, highlighting the potential utility of a PNF intervention specifically for RSB. The current study tested the utility of a web-based PNF intervention to correct normative perceptions regarding condom use as well as to increase condom use among college students. A sample of 189 undergraduate students (80.6% female, 62.2% non-Hispanic Caucasian) who …

Assessing Changes In Self-Reported Driving Ability After Mild Traumatic Brain Injury, John Philip Kelly Bernstein

LSU Master's Theses

The ability to safely drive a car requires intact cognitive functioning across a variety of domains, many of which are adversely affected following a moderate-to-severe traumatic brain injury (TBI). Mild traumatic brain injury (mTBI) impacts similar cognitive facets, albeit to a less severe extent, and preliminary evidence suggests that mTBI may also have a deleterious effect on driving abilities immediately following injury. However, changes in driving ability over the course of recovery from mTBI have not been adequately examined. The present study addressed this dearth in the literature through examination of self-reported driving ability in 18 participants with a recent …

Vocal Expression In Schizophrenia: Examining The Role Of Vocal Accommodation In Clinical Ratings Of Speech, Thanh P. Le

LSU Master's Theses

Diminished vocal expressivity, defined in terms of a diminution in speech production and intonation/emphasis, is a chronic symptom in schizophrenia. On interview-based measures of vocal deficits, clinicians typically rate patients with schizophrenia 4 to 6 SDs below their non-patient peers. However, recent studies utilizing objective computerized measures have failed to observe vocal expressivity deficits that approach this level. It may be that vocal deficits can only be understood within the boundaries of dyadic exchanges during interview-based assessments. Vocal accommodation, or the degree to which vocal characteristics (i.e., mean F0) between interlocutors synchronize over time, has been linked to enhanced social …
