The Effects Of Paired Kinesthetic Movements And Embedded Pictures On Literacy Skills With Preschoolers, Erica Lozy

LSU Doctoral Dissertations

Reading difficulties during childhood often continue during adulthood and result in adverse effects (e.g., unemployment, poverty). A common method to teach early literacy skills is via multisensory instructional programs, which use combinations of mnemonic devices, such as visual, auditory, tactile, and kinesthetic movements. The current literature on the effects of pairing visual mnemonics and kinesthetic movements with literacy skills, either in isolation or in combination, is sparse. The purpose of Study 1 and Study 2 was to compare the efficacy, generalization, and maintenance of and preference for letter sound interventions with and without mnemonic devices. Study 1 evaluated a traditional …

A Relational Study Of Self-Taught And Formally Trained Musicians: Trends Within Memory And Socioeconomic Factors, Matthew N. Jimenez, Emily M. Elliott

LSU Master's Theses

It has been well documented that musicians perform better in memory tasks than non-musicians. The current study utilized self-taught musicians, formally trained musicians, and non-musicians, and focused on short-term memory (STM), musicianship, and SES factors to explore this finding. Do the memory benefits of musical training extend to self-taught musicians? First, we addressed musicianship amongst all groups using the Goldsmith’s Musical Sophistication Index (GMSI), which contained subjective and objective measures. The subjective measure was a survey regarding the role of music in daily life. In the objective measures, participants completed tests of beat and melody perception. To measure STM, participants …

Organizational Commitment Profiles And Employee Well-Being: A Latent Profile Analysis, Hannah E. Perkins

LSU Master's Theses

The present study examined the influence that employees’ organizational commitment profile has on both work and non-work outcomes. While the nomological network of the three-component model of organizational commitment has been studied widely, the application of the latent profile analysis (LPA) has changed the way researchers explore organizational commitment. Specifically, while variable centered approaches (e.g., correlations, multiple regression) measure each type of commitment independently and ultimately assume the linear relationships detected are applicable to every employee, a person-centered approach (e.g., latent profile analysis) groups individuals according to patterns of the reported target variables, allowing researchers to explore the combined or …

Does Chronic Risperidone Administration Affect Food Reinforcement In Adulthood In Mice?, Francis Torres, Paul Soto

LSU Master's Theses

Second-generation antipsychotics (SGAs) increase weight gain and food consumption in humans and non-human animals. It has been speculated that SGAs increase the reinforcing effects of food, which increases food consumption and drives weight gain. The current study evaluated the effects of risperidone on sucrose reinforcement in male and female C57BL/6J mice using economic demand assessments. Demand for sucrose was measured by varying the fixed ratio (FR) value required to produce sucrose delivery across experimental sessions using five FR values: 1, 5, 15, 30, and 45. The effects of acute risperidone administration on demand for sucrose were first assessed by orally …

The Use Of Non-Immersive Virtual Reality As A Functional Rehabilitation Tool For Older Adults With Cognitive Decline, Ross M. Divers

LSU Master's Theses

There is currently no cure for age-related cognitive decline or dementia and current pharmacologic interventions have had limited success at improving daily functioning. Consequently, older adults who experience cognitive decline require assistance with daily activities, which can be quite expensive and lead to caregiver burden. Repeated performance of everyday tasks has been shown to improve performance but requires supervision and direction by another person. The present study evaluated a low-cost computer training program that will use non-immersive virtual reality to enable participants with dementia or cognitive decline to independently practice meaningful everyday activities (e.g., meal preparation). Participants (N= 8) with …

The Influence Of Clutter On Target Prevalence And Decision Making During Visual Search, Brandon Eich

LSU Master's Theses

Participants are sensitive to target prevalence effects in visual search. Low prevalence of targets leads to increased miss rates and shorter response times, and high prevalence of targets leads to increased false alarm rates and longer response times. These effects have been explained using the Multiple-Decision Model (MDM), in which two decisions impact performance during serial visual search. The first decision is whether an inspected item is a target. The second decision is whether the search should be ended with a target-absent response. Target prevalence influences these decisions, evidenced by changes in miss rate, false alarm rate, and response time. …

Examining The Relationship Between Functionally Assessed Parental Behavior And Child Anxiety, Allison Smith

LSU Master's Theses

Etiological theories of child anxiety suggest an interaction of multiple factors that lead to the development and maintenance of child anxiety. Environmental influence, specifically that involving the family or parent, has been a target area of study for decades. Additionally, functional assessment of behavior indicates that certain behaviors may be maintained primarily by specific functions. Functional assessment has been successful at identifying functions of problematic behavior and planning treatment accordingly. However, in the realm of child internalizing disorders, research has not utilized functional assessment in this way. Acknowledging the impact of parental behavior on child anxiety as well as the …

Visuomotor Rotation Adaptation And Workspace Manipulation: A Behavioral And Cognitive Emphasis, Reuben N. Addison

LSU Doctoral Dissertations

This is a three-study dissertation in which we aimed to broaden our knowledge of the mechanisms contributing to a 45° clockwise visuomotor adaptation by including variations in workspace. We provide behavioral and in one study physiological outcomes as evidence to support our conclusions. In the first experiment, we observed the adaptation of movement parameters such as pathlength, movement time, resultant velocity, and normalized jerk across groups trained with rotated visual feedback with both the left and right hands. Workspace location and hand differentially affected movement trajectory length. The group that practiced the task with their nondominant, left hand showed larger …

Mindfulness And Physical Activity As Moderators Of Behavioral Inhibition Sensitivity And Psychological Distress, Edward Silber

LSU Master's Theses

Framed in Reinforcement Sensitivity Theory, the current study examined the moderating effects of mindfulness and moderate-to-vigorous physical activity (MVPA) on the relationship between behavioral inhibition system (BIS) sensitivity and psychological distress. Participants (N=183) were college students at a large public university in the Southeastern United States. Data were collected using an online survey with self-report questionnaires that demonstrated acceptable reliability. Data analysis utilized multiple linear regression models to test study hypotheses. Findings revealed a significant positive relationship between BIS sensitivity and psychological distress, with mindfulness and MVPA significantly moderating this association. Specifically, increased reports of mindfulness and MVPA …

Evaluation Of Hippocampal Allostatic Load-Associated Factors In Animal Models Of Post-Traumatic Stress Disorder: Relevance To Human Ptsd, Dennis Parker Kelley

LSU Doctoral Dissertations

Post-traumatic stress disorder (PTSD) is associated with elevated allostatic load, nearly double the risk for metabolic syndrome, reduced hippocampal volume, and contextual memory processing deficits. Emerging evidence suggests that these stress effects may predispose individuals to the development of PTSD, and there is a known relationship between chronic stress and metabolic dysfunction. In this work, we utilized two rat models of PTSD to explore these connections. We used an acute predator odor stressor to investigate the relationship between PTSD-like behaviors and mitochondrial dysfunction in the hippocampus of rats, and we observed that conditioned place avoidance was associated with reduced mitochondrial …

Caregiver Treatment Consumption In An Experimental Treatment Marketplace, Delaney J. Darragh

LSU Master's Theses

Behavioral economics is an approach to understanding consumer behavior by integrating behavioral science with economic principles. Behavioral economics incorporates traditional economic principles with operant learning approaches. There is limited research examining how individuals consume psychological and behavioral treatments. This is especially the case for treatments designed for children. The current study used data from a previously collected sample to explore gender differences in an experimental treatment marketplace (ETM). Experimental treatment marketplaces are generally used to evaluate choices between goods and services (e.g., types of behavior interventions). An ETM was developed to evaluate treatment consumption when levels of evidence differed between …

The Effects Of Team Surface-Level Diversity On Creativity & Innovation, Roman Mitchell

Faculty Publications

During the last 20 years, the global marketplace has become more competitive due to increased globalization, aggressive market competition, and changing customer demands. This has forced organizations to assemble teams with diverse knowledge, skills, and abilities to remain competitive. However, previous meta-analytic investigations examining the relationship between team surface-level diversity (i.e., race or gender identity), creativity, and innovation have indicated a small negative relationship. Despite the said positive effects of team diversity, theory and empirical evidence suggests that increased surface-level team diversity leads to decreased team collaboration, team cohesion, and diminished creativity and innovation (Bell, 2007).

This study explores the …

An Investigation Of How Previous Diagnoses Affect The Developmental Functioning Of Children At Risk For Autism Spectrum Disorder, Michaela Brown

LSU Master's Theses

Research has shown that children with autism spectrum disorder (ASD) often have co-occurring medical and/or psychiatric disorders. This current study aimed to investigate how previous diagnoses, which may become comorbidities of ASD if diagnosed, affect the developmental functioning of children presenting as at risk for ASD compared to those presenting with no risk. Developmental areas such as communication, motor, adaptive, cognitive and social, as well as overall developmental functioning, were considered in the analysis. 11,970 children under the age of three were studied. Results found that the presence of previous diagnoses significantly predicted developmental functioning, particularly in the motor functioning …

Developmental Functioning Of Infants And Toddlers With Neurodevelopmental Disorders, Megan Callahan

LSU Master's Theses

Autism spectrum disorder (ASD), epilepsy, and cerebral palsy (CP) are some of the most common neurodevelopmental disorders among children with prevalence rates of 1.85% (Maenner et al., 2020), 1.2% (Zack & Kobau, 2017), and between 0.21 and 0.31% (Christensen et al., 2013), respectively. These neurodevelopmental disorders are highly comorbid with each other and with other disorders, such as intellectual disability (ID). While previous research has investigated developmental functioning in these neurodevelopmental disorders, it has primarily focused on only two at a time and in older children or adults. The current study aimed to investigate developmental functioning in these neurodevelopmental disorders …

The Contributions Of Immediate Retrieval And Spaced Retrieval To Word Learning In Preschoolers With Developmental Language Disorder, Laurence B. Leonard, Justin B. Kueser, Patricia Deevy, Eileen Haebig, Jeffrey D. Karpicke, Christine Weber

Faculty Publications

Background and Aims: Children with developmental language disorder (DLD) benefit from word learning procedures that include a mix of immediate retrieval and spaced retrieval trials. In this study, we examine the relative contribution of these two types of retrieval.

Methods: We examine data from Haebig et al. (2019) in their study that compared an immediate retrieval condition and a condition of spaced retrieval that also included immediate retrieval trials. Participants were 4- and 5-year old children with DLD and same-age peers with typical language development. Each child learned novel (made-up) words referring to unusual plants and animals in both conditions. …

The Predictive Influence Of Challenging Behavior On Parent Stress In Young Children With Autism Spectrum Disorder, Paige Weir

LSU Master's Theses

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social communication, restricted interest, and repetitive patterns of behavior. Individuals with ASD also exhibit challenging behaviors that affect parent and caregiver stress directly. However, researchers have not yet examined the predictive influence of specific challenging behaviors on parent stress, particularly in young children (i.e., infants and toddlers) with ASD. Therefore, the current study expands existing literature by a) investigating the influence that challenging behaviors of young children with ASD have on parent stress and b) examining the unique contribution that each behavior (i.e., aggressive/disruptive behavior, stereotypy, and self-injurious …

Efficiency Of Teaching Sight Words In Similar Vs Dissimilar Sets, Jensen Chotto

LSU Master's Theses

Early reading intervention can decrease the likelihood that children who struggle with reading develop long-term reading problems. Due to the prevalence of words that cannot be read phonetically in the English language, sight word instruction is required to supplement phonics instruction. In this study, we compared the effects of creating sets of sight words with the same starting letter (3 words per set, 3 total sets) versus distributing words with the same starting letter across sets when assessing acquisition of the combined set (9 words) in five 4-to-6-year-old children using a combined adapted alternating treatments design and pre-posttest design. All …

A Systematic Review And Reflection On The Dimensions Of Diversity Represented In Behavior Analytic Research, Jodie Waits

LSU Master's Theses

The United States continues to transition towards a majority-minority composition and this trend has most rapidly emerged for school-aged children. Work with diverse populations calls for specialized skills and training experiences, but these are not strongly reflected in most training programs in Applied Behavior Analysis (ABA). The present review was conducted to evaluate the scope and range of the dimensions of diversity included in Behavior Analytic research (e.g. race/ethnicity, gender, sexuality, etc.), as well as to compile recommendations related to culturally responsive practice in ABA. The search revealed a total of 50 publications featuring a dimension of diversity. These works …

An Erp Study Of The Effects Of Iconic And Nonsense Gestures On Memory Formation, Brianna E. Cairney

LSU Master's Theses

Co-speech gesture is an important part of human communication and aids in comprehension, learning, and memory. The addition of iconic gestures to speech has been shown in prior work to enhance memory for the speech. However, it remains unclear as to whether this benefit requires gestures to be meaningful, or, conversely, if any attentionally-engaging gesture will enhance memory. In the current study, we tested two theories to explain the mnemonic benefits of co-speech gesture: Dual Coding Theory, which attributes these benefits to multimodal encoding and enhanced imageability, and Attentional Highlighting Theory, which posits that gestures draw more attention to concurrent …
