Youth's Political Identity And Fertility Desires, Heather M. Rackin, Christina M. Gibson-Davis

Faculty Publications

Objective: This study examines the association between political identity and young adults' fertility desires from 1989 to 2019. Background: Understanding the factors that shape fertility preferences is important because these preferences are the critical bridge between social forces and fertility. Identity is a theorized, but understudied, predictor of fertility desires. The increasing salience of political identity suggests that the association between political identity and fertility desires has strengthened over time. Method: Data come from the 1989–2019 waves of Monitoring the Future, a nationally representative study of 12th graders (N = 67,557). Regression models examined how political identity (measured by Republican …

Precision Nutrition For Management Of Cardiovascular Disease Risk During Menopause, Hannah E. Cabre, Emily K. Woolf, Leanne M. Redman

Clinical Research Faculty Publications

Background:Women can spend up to 40%of their lives in the postmenopausal state. As women begin to transition into menopause, known as perimenopause, changes in hormonal concentrations and body composition dramatically increase overall cardiometabolic risk. Dietary patterns and interventions can be utilized to prevent and treat cardiovascular disease (CVD) and some dietary patterns over others may be more beneficial due to their specific effects on the health aspects of menopause. In this narrative review, we summarize key cardiovascular alterations that occur during the menopause transition and explore current dietary recommendations to address CVD risk aswell as explore the newfrontier of precision …

An Analysis Of The Development Of Cognitive Control In Young Children Within An Auditory And Visual Modality., Lauren A. Schiro

LSU Master's Theses

The Dual Mechanisms of Cognitive Control Framework (DMC) posits that cognitive control is directed through two different modes: proactive and reactive control. Proactive control involves the maintenance and manipulation of information in preparation of a response while reactive control would involve little to no preparation until after a response prompt. The AX-Continuous Performance Task (AX-CPT) is a cognitive control task that is often utilized in studies looking at proactive and reactive control as it measures context processing and goal maintenance. The aims of this study were to validate the auditory version of the AX-CPT and to then apply this task …

A Confirmatory Factor Analysis Of The Psi-4-Sf In Parents Of Children With Autism Spectrum Disorder, Paige Weir

LSU Doctoral Dissertations

The factor structure of the Parenting Stress Index - Short Form (PSI-4-SF) was evaluated among parents of children with autism spectrum disorder (ASD). Two hypotheses were tested: (1) the original PSI-4-SF model would yield an unsatisfactory fit, and (2) a three-factor alternative model would improve fit compared to the original and other models. A sample of 205 parent-child dyads was analyzed using confirmatory factor analysis (CFA) with the lavaan package in R Studio. Preliminary analyses included descriptive statistics, normality checks, and assessments of skewness and kurtosis. Results supported the first hypothesis, showing poor fit indices for the original PSI-4-SF model. …

Examining Social Anxiety, Generalized Anxiety, And Major Depression’S Symptom Comorbidity In Children And Adolescents: A Longintudinal Test Of The Multiple Pathway Model, Paige Picou

LSU Doctoral Dissertations

Anxiety and depressive disorders are highly prevalent in and impairing for children and adolescents and are highly comorbid. Many theories have been proposed to explain this co- occurrence, with recent models postulating multiple pathways in which specific anxiety disorders and depression may co-occur both concurrently and over time. Unfortunately, little research has evaluated these pathways longitudinally across development in a community sample. The current study tested the multiple pathway model in a sample of 9 to 12-year-old youth (Mage = 9.48, SD= 0.51) at baseline and at two-year follow-up using a subsample of the Adolescent Brain Cognitive Development …

Towards Addressing Mental Health In Rural Louisiana: Blueberry Supplementation As A Natural Intervention, Katy E. Venable

LSU Doctoral Dissertations

Depression and anxiety are major public health issues; however, there is an unmet need for novel effective and accessible treatments, particularly in rural communities. Blueberries are an unexplored nutraceutical for these conditions due to their excellent nutritional profile, with particularly high levels of polyphenols and anthocyanins and benefits on mood, cognition, and health. Therefore, we conducted a double-blind, randomized pilot study in a rural population. We employed a cross-over design to test the effects of 12 weeks daily ingestion of 24 g of whole freeze-dried blueberry powder versus placebo on symptoms of depression and anxiety in those diagnosed with depression …

Asmrtistry In Immersive Sound: Investigating The Effectiveness Of Immersive Sound Technologies In Eliciting Autonomous Sensory Meridian Response, Scott D. Nelson

LSU Doctoral Dissertations

Despite a wide array of immersive sound technologies available to digital media creators who specialize in making audio-visual content that aims to elicit Autonomous Sensory Meridian Response (ASMR), only a few sound reproduction modalities are widely used: mono/stereo and binaural recording. To date, nearly all research studying ASMR, a bio-sensory phenomenon wherein people feel brain tingles triggered by calming audio-visual cues, has been content to carry out ASMR studies entirely with stereo and binaural sound reproduction methods. Therefore, it stands to reason that more understanding about how diverse immersive sound modalities like wave field synthesis, or three-dimensional spatial audio for …

Assessing Team Performance And Cohesion Of Isolated Multicultural Teams Using Digital Escape Rooms, Susannah J. Aronson

LSU Doctoral Dissertations

History has shown that when multicultural teams are together for long periods of time, conflict can occur. When put in an isolated environment, these conflicts can become dangerous. This study looked at physically isolated multicultural teams through the lens of systems engineering and if a publicly available escape room video game could measure the team’s individual level team performance and cohesion. The author also evaluated the relationship between these success measures, cultural intelligence, and fusion collaboration. Results showed the escape room video game was a reliable and valid instrument to measure individual level team performance and cohesion. The validity correlation …

Optimizing Associative Memory In Autistic And Non-Autistic Adults: Retrieval Practice, Post-Retrieval Feedback, And Gesture, Brianna E. Cairney

LSU Doctoral Dissertations

Associative memory—or the ability to form a memory representation linking two previously unrelated concepts—is a critical aspect of learning. This work provides insight into strategies that can be used to support associative memory, their underlying mechanisms, and their effectiveness in autistic and non-autistic learners. Chapter 1 demonstrates that iconic gestures can be used as a tool to enhance associative memory by increasing word concreteness and imageability. This effect was eliminated when the iconic gestures were interspersed with ambiguous nonsense gestures, suggesting a boundary on these benefits that depends on listener expectations regarding gesture clarity. However, it remains unknown whether gestures …

Hd-Tdcs Over Left Supplementary Motor Area Differentially Modulated Neural Correlates Of Motor Planning For Speech Vs. Limb Movement, Fatemeh Tabari, Celeste Patron, Hope Cryer, Karim Johari

Faculty Publications

The supplementary motor area (SMA) is implicated in planning, execution, and control of speech production and limb movement. The SMA is among putative generators of pre-movement EEG activity which is thought to be neural markers of motor planning. In neurological conditions such as Parkinson's disease, abnormal pre-movement neural activity within the SMA has been reported during speech production and limb movement. Therefore, this region can be a potential target for non-invasive brain stimulation for both speech and limb movement. The present study took an initial step in examining the application of high-definition transcranial direct current stimulation (HD-tDCS) over the left …

Transcription Decisions Of Conjoined Independent Clauses Are Equitable Across Dialects But Impact Measurement Outcomes, Janna B. Oetting, Tahmineh Maleki

Faculty Publications

Purpose: Transcription of conjoined independent clauses within language samples varies across professionals. Some transcribe these clauses as two separate utterances, whereas others conjoin them within a single utterance. As an inquiry into equitable practice, we examined rates of conjoined independent clauses produced by children and the impact of separating these clauses within utterances on measures of mean length of utterance (MLU) by a child’s English dialect, clinical status, and age. Method: The data were archival and included 246 language samples from children classified by their dialect (African American English or Southern White English) and clinical status (developmental language disorder [DLD] …

A Longitudinal Evaluation Of Personalized Intrinsic Network Topography And Cognitive Decline In Parkinson's Disease, Renxi Li, Vincent Pozorski, Kevin Dabbs, Maureen Haebig, Christopher R. Cox, Colleen Pletcher, Alexandra Wey, Amy Barzgari, Frances Theisen, Ozioma Okonkwo, Catherine L. Gallagher

Faculty Publications

Resting state functional magnetic resonance imaging (R-fMRI) offers insight into how synchrony within and between brain networks is altered in disease states. Individual and disease-related variability in intrinsic connectivity networks may influence our interpretation of R-fMRI data. We used a personalized approach designed to account for individual variation in the spatial location of correlation maxima to evaluate R-fMRI differences between Parkinson's disease (PD) patients who showed cognitive decline, those who remained cognitively stable and cognitively stable controls. We compared fMRI data from these participant groups, studied at baseline and 18 months later, using both network-based statistics (NBS) and calculations of …

Clinical Research Faculty Publications

The characterization of human behavior in real-world contexts is critical for developing a comprehensive model of human health. Recent technological advancements have enabled wearables and sensors to passively and unobtrusively record and presumably quantify human behavior. Better understanding human activities in unobtrusive and passive ways is an indispensable tool in understanding the relationship between behavioral determinants of health and diseases. Adult individuals (N = 60) emulated the behaviors of smoking, exercising, eating, and medication (pill) taking in a laboratory setting while equipped with smartwatches that captured accelerometer data. The collected data underwent expert annotation and was used to train a …

A (Dynamic) Investigation Of Stereotypes, Belief-Updating, And Behavior, Katherine Coffman, Maria Paola Ugalde Araya, Basit Zafar

Faculty Publications

Using a controlled experiment, we study the dynamic effects of feedback on decision-making across verbal skills and math. Before feedback, men are more optimistic about their performance and more willing to compete than women, especially in math. While feedback shifts individuals' beliefs and behavior, we see substantial persistence of gender gaps 1 week later. This is particularly true among individuals who receive negative feedback. Our results are not well-explained by motivated reasoning; in fact, negative feedback is more likely to be recalled than positive feedback. Overall, our results highlight the challenges involved in overcoming gender gaps in dynamic settings.

Presidential Stories Of Fear: Focusing Congressional Climate Change Mitigation Attention In The United States, Holly L. Peterson, Chad Zanocco

Faculty Publications

Do presidential climate change narratives increase related congressional attention in the United States? Narrative theory says since narratives leverage cognitive heuristics, they should focus policy-making attention in institutions more efficiently than non-narrative statements. This study identifies and tests climate change statements and narratives, including those focused on solutions, or “stories of hope,” and those focused on problems and victims, “stories of fear,” for relationships with congressional attention using time series analysis. Findings suggest a relationship between narrative and hearings, but not for non-narrative statements and hearings. Furthermore, while narratives are related to hearings generally, stories of fear have larger effects, …

Language Discrimination Using Bilingual Picture Exchange For Culturally And Linguistically Diverse Children With Autism Spectrum Disorder, River Waits

LSU Doctoral Dissertations

Recent research suggests that one-fifth of United States households use non-English languages in the home setting. Ethically and effectively supporting culturally and linguistically diverse (CLD) clients (e.g., autistic individuals) presents a growing challenge to practitioners of Applied Behavior Analysis (ABA). Though efforts to address the linguistic needs of the population have grown in recent years, current literature focuses on language selection for monolingual services and underemphasizes the need for bilingual service provision. Studies were conducted to (I) evaluate the efficacy of bilingual picture exchange (i.e., mand response) across items, speakers, and languages (i.e., English and Spanish) as well as (II) …

Academic Support Programs At Hbcu Law Schools, Marla L. Dickerson

LSU Doctoral Dissertations

This qualitative descriptive case study delves into the effectiveness of academic support programs (ASPs) for students at Historically Black Colleges and Universities (HBCU) law schools, focusing on enhancing academic performance and passing the bar exam. The underrepresentation of minority lawyers in the United States, which is attributed partly to standardized test disparities, underscores the need for tailored support mechanisms. Drawing from social cognitive theory (SCT), the study investigates how ASPs impact academic success, informed by participant interviews and thematic analysis.

Key findings reveal four prominent themes. Firstly, effective features of ASPs for promoting academic performance include personalized guidance from academic …

The Collaborative Assessment And Management Of Suicdality As A Single Session Intervention For Patients Admitted To Inpatient Psychiatric Care For Suicidal Thoughts And Behaviors, D Nicolas Oakey-Frost

LSU Doctoral Dissertations

Inpatient psychiatric care is a critical contact point for individuals experiencing suicidal thoughts and behaviors (STB). The Zero-Suicide framework provides useful scaffolding for improving suicide prevention within inpatient psychiatry (i.e., Assess, Intervene, and Monitor [AIM-SP]). Available evidence suggests instruments are available for evidence informed risk assessment but are hindered by low construct validity and a limited collaborative approach. Additionally, extant interventions do not typically target STB and are not optimized for inpatient psychiatric care. The Collaborative Assessment and Management of Suicidality (CAMS) meets the criteria of the Zero-Suicide Framework and is often leveraged as a single session intervention (SSI) but …

Emotional Reactivity And Recognition Deficits In Individuals With Callous-Unemotional (Cu) Traits: A Multilevel Meta-Analysis, Emily C. Kemp

LSU Doctoral Dissertations

Youth and adults with antisocial behavior present a significant mental health concern. Elevated callous-unemotional (CU) traits, characterized by deficient empathy and remorse, distinguish clinically important subgroups of antisocial individuals who present with more severe behavior and distinct cognitive-affective characteristics that may help to explain the underlying causes of their antisocial behavior and inform more effective treatments. Specifically, two mechanisms theorized to underlie the development of elevated CU traits by way of atypical empathy development are deficient reactivity to and recognition of others’ emotions. Though a substantive literature base reports associations between CU traits and emotional processing deficits, significant inconsistencies remain. …
