The reviewer concludes that while suitable for introductory courses, both textbooks would benefit from supplemental materials and critical reflection questions to enhance student learning and address potential biases.


Promoting Emergent Literacy In Preschool Through Extended Discourse: Covert Translanguaging In A Mandarin Immersion Environment, Robin E. Harvey, Kevin M. Wong Aug 2024

Promoting Emergent Literacy In Preschool Through Extended Discourse: Covert Translanguaging In A Mandarin Immersion Environment, Robin E. Harvey, Kevin M. Wong

Education Division Scholarship

Rich oral language practices, including the opportunity and ability to participate in cognitively and linguistically challenging extended discourse, are foundational to early literacy development. To meet children’s needs in their first exposure to the languages of schooling, educators may engage students in extended discourse multilingually. The current study focuses on student-centered translanguaging conversations to examine strategies that preschool teachers employ to support young children’s emerging bilingual and biliteracy development in a Mandarin immersion preschool serving primarily nonheritage learners of Mandarin in the United States. Findings indicate that, despite the school’s Mandarin-only policy, teachers engaged in covert translanguaging practices to extend …

Emotional Response In Working Memory Of Individuals With Latent Toxoplasmosis, Antonella Quimbayo Aug 2024

Emotional Response In Working Memory Of Individuals With Latent Toxoplasmosis, Antonella Quimbayo

All HCAS Student Capstones, Theses, and Dissertations

Toxoplasma gondii is a prevalent parasite that infects about 30% of the world population. House cats and other felids serve as definitive hosts and acquire Toxoplasma by consuming infected prey, which are intermediate hosts. This includes rats and avians, but also large mammals such as wolves and deer. Toxoplasma gondii is known to manipulate prey behavior to enhance its transmission. For example, infected rodents demonstrates attraction to and curiosity around cat urine. Wolves infected with Toxoplasma were 11 times more likely to disperse from their pack and start a new pack. The manipulation of intermediate host behavior observed in rodents …


Reflections And Revelations In Autoethnography: A Review Of Meaningful Journeys Of Quest And Identity Transformation, Niroj Dahal Aug 2024

Reflections And Revelations In Autoethnography: A Review Of Meaningful Journeys Of Quest And Identity Transformation, Niroj Dahal

The Qualitative Report

In this review of—Meaningful Journeys: Autoethnographies of Quest and Identity Transformation, edited by Alec Grant, Ph.D., and Elizabeth (Lizzie) Lloyd-Parkes, Ph.D., I have made an effort to offer my evaluation that explores the autoethnographies of quest and identity transformation (Grant & Lloyd-Parkes, 2024). The book presents a curated anthology of personal ethnographic narratives, each grounded in the foundational concepts, philosophical insights, and linguistic roots of “journeying,” “questing,” and both ancient and contemporary interpretations of “pilgrimage.” As an autoethnographer, even during the different phases of life—personal and professional—I have been through the different roots of transformation, and now, at …


Assessing Comprehension And Competence In Bottlenose Dolphins (Tursiops Truncatus) On The Concept: Do Something Different, Charlotte M. Mulligan Aug 2024

Assessing Comprehension And Competence In Bottlenose Dolphins (Tursiops Truncatus) On The Concept: Do Something Different, Charlotte M. Mulligan

Theses and Dissertations

Many studies have been conducted using a training paradigm based on the research of Pryor et al. (1969) wherein the participants are trained on the abstract concept: do something different. This paradigm challenges working memory and requires the participants to respond with a behavior, either previously trained or novel, which has not yet been offered within the session. The work of Braslau-Schneck (1994) expanded this concept and demonstrated the ability of dolphins to successfully complete this task in synchronized pairs, though the method of accomplishing this task remained unclear. The present research was conducted as part of a broader …


The Effect Of The Lunar Cycle On The Demographics Of Asian Elephants Observed In Open Areas In A Protected Wildlife Sanctuary And Surrounding Crop Fields, Serene K. Rivera Aug 2024

The Effect Of The Lunar Cycle On The Demographics Of Asian Elephants Observed In Open Areas In A Protected Wildlife Sanctuary And Surrounding Crop Fields, Serene K. Rivera

Theses and Dissertations

Due to human development and habitat fragmentation, Asian elephants increasingly use human landscapes and encounter people. These interactions have led to negative interactions between humans and elephants, such as crop-raiding. Despite efforts to mitigate these conflicts, farmers have not been able to consistently protect their crops from elephant foraging. Therefore, it is important to understand elephant behavior in these landscapes to help create long term mitigation plans. Specifically, research regarding demographic patterns in Asian elephants’ perceived predation risk can inform wild elephant management. This study used camera traps in Salakpra Wildlife Sanctuary in Kanchanaburi, Thailand to observe the wild Asian …


High Fat Diet & Social Isolation: Interactive Effects On Pain, Cognition, & Neuroinflammation, Ian M. Campuzano Aug 2024

High Fat Diet & Social Isolation: Interactive Effects On Pain, Cognition, & Neuroinflammation, Ian M. Campuzano

Research Psychology Theses

Prior research has established a role for both social isolation and exposure to high fat Western diets in altering a range of behaviors from reduced memory performance to increased depression-like behaviors. The present study scrutinizes the interplay among these variables during the peri-adolescent developmental phase, utilizing Long-Evans rats as the experimental model. Our overarching hypothesis is that rats exposed to either social isolation, a high-fat diet, or both will result in heightened pain sensitivity, diminished cognitive flexibility, and increased neuroinflammatory responses within brain regions implicated in sociability, cognition, memory, and pain processing. Behavioral flexibility will be assessed using a maze-based …


Wired For Success: A Neurobiological Approach To Improving The Academic Outcomes Of Middle School Boys, Allison Emery Aug 2024

Wired For Success: A Neurobiological Approach To Improving The Academic Outcomes Of Middle School Boys, Allison Emery

University Honors Theses

Male accomplishment in scholastic settings has been declining globally for the last decade, leading to long-term consequences for boys and men. Possible neurobiological underpinnings of the gender gap in education are discussed in this literature review. While male and female differences have, in the past, largely been considered socialized, recent science also confirms neurobiological variances between male and female development. These distinctions are assessed for their potential ties to the decline in male academic success, and are correlated to classroom practices, strategies and interventions meant to increase boys' engagement and performance.


An Analysis Of The Development Of Cognitive Control In Young Children Within An Auditory And Visual Modality., Lauren A. Schiro Jul 2024

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 …

Faculty, Staff and Student Publications

Structural neuroimaging data have been used to compute an estimate of the biological age of the brain (brain‐age) which has been associated with other biologically and behaviorally meaningful measures of brain development and aging. The ongoing research interest in brain‐age has highlighted the need for robust and publicly available brain‐age models pre‐trained on data from large samples of healthy individuals. To address this need we have previously released a developmental brain‐age model. Here we expand this work to develop, empirically validate, and disseminate a pre‐trained brain‐age model to cover most of the human lifespan. To achieve this, we selected the …

These profiles can then be used to identify users securely and efficiently, even in the presence of sophisticated attacks, by harnessing AI-driven systems for mental profile creation and user authentication.

After reviewing the existing literature on authentication and mental profiling, it presents a new mental profiling test that is specifically designed for authentication purposes. The test was evaluated on a sample of 100 users, and results …


Neuroscience And Organizational Trust: Biological Mechanisms For Enhanced Learning, Rob E. Carpenter Jun 2024

Neuroscience And Organizational Trust: Biological Mechanisms For Enhanced Learning, Rob E. Carpenter

Human Resource Development Faculty Publications and Presentations

Individual representations of trust are deeply rooted in individual consciousness and serve as significant cognitive constraints, influenced by neural processes and psychiatric factors. This paper aims to highlight the often overlooked or under-operationalized role of human trust's biological agency within the context of organizational learning. From a psychiatric and neuroscience perspective, the paper proposes that through intentional management practices, the biological agency of trust, mediated by neural mechanisms, can act as a proxy for organizational learning. It suggests that adopting a more scientific approach to management, informed by an understanding of neural and psychiatric underpinnings, can enhance employee trust from …

Biofeedback Gaming For Substance Use Disorder, Rebecca L. Chevrel Jun 2024

Biofeedback Gaming For Substance Use Disorder, Rebecca L. Chevrel

University Honors Theses

Substance Use Disorder (SUD) and stress are often predictive of one another, bidirectionally causal, and mutually intensifying. This thesis describes the bi-directional connection between physiological stress-modulating systems and Substance Use Disorder, and explores some emerging biofeedback stress-reduction gaming technology as a potential adjunct to recovery treatments. Improving autonomic balance, often described by Heart Rate Variability, has been shown to be beneficial for physical and psychological recovery, as well as improving self-control. For this reason, regular biofeedback for stress relief could be helpful in augmenting SUD treatment and preventing relapse. This exploration found that presenting it through a gaming lens may …


Attrition And Assimilation: The Neural Mechanisms Of Mandarin-English Bilingualism, Natalie Paige Robison Jun 2024

Attrition And Assimilation: The Neural Mechanisms Of Mandarin-English Bilingualism, Natalie Paige Robison

University Honors Theses

This line of research investigates attrition of native language (L1) Mandarin proficiency with increasing proficiency in English. English uses pitch to denote intonation (e.g., "it's there?" versus "it's there!"), while Mandarin additionally uses pitch to indicate word meanings; e.g., /he/ means "drink" when spoken with a high, level tone, or "river" when spoken with a rising tone. The present study delineates between two alternative explanations for the prior finding that English proficiency correlates with attrition of Mandarin tones, but not Mandarin vowels. This pattern could be explained by 1) assimilability of the Mandarin vowel contrasts used in the study into …


Exploring Cultural, Health, And Technology Intersections: A Focus On Migrant Experiences, Merna Mina, Sahij Gill Jun 2024

Exploring Cultural, Health, And Technology Intersections: A Focus On Migrant Experiences, Merna Mina, Sahij Gill

Bridges: An Undergraduate Journal of Contemporary Connections

Despite the plethora of theories and frameworks addressing culture, health, and technology adoption, there remains a notable absence of a unifying theory that comprehensively encompasses all three aspects, particularly concerning newcomers. The Health Belief Model, for example, underscores individual perceptions and attitudes toward health yet fails to consider the intricate interplay between cultural factors and technology adoption among immigrant populations. The Healthy Immigrant Effect, which posits that immigrants often exhibit better health outcomes than native-born individuals, does not mention the role of technology on health outcomes. Acculturation theories, while shedding light on the adaptation process, often fall short of explaining …

Examining Visual Processing Of Hierarchical Figures Through Behavioral Measures And Pupillometry In Relation To Autistic Traits In Adults, Chloe Brittenham Jun 2024

Examining Visual Processing Of Hierarchical Figures Through Behavioral Measures And Pupillometry In Relation To Autistic Traits In Adults, Chloe Brittenham

Dissertations, Theses, and Capstone Projects

Autism spectrum disorder (ASD) and autistic traits in the general population are associated with differences in sensory processing, particularly within the visual domain. Previous studies examining global (i.e., overall gist) and local (i.e., detail) visual processing in relation to ASD have sometimes yielded contradictory findings yet converge on a common theme: slowed global processing and increased local bias associated with ASD. Despite this consensus, the mechanism underlying these differences remains unclear, whether it be differences in visual attention, higher or lower visual perception, and/or cognitive style. The use of traditional tasks and stimuli may further complicate the understanding of contributing …


Flanker Task Performance In Young And Older Adults: A Behavioral And Erp Study, Fatima Medrano Jun 2024

Flanker Task Performance In Young And Older Adults: A Behavioral And Erp Study, Fatima Medrano

Dissertations, Theses, and Capstone Projects

Research suggests that as we get older, executive function abilities decline (Hasher & Zacks, 1988; Salthouse, 1996). One affected ability is that of inhibitory control, which aids in monitoring our responses to non-target stimuli or information. Current research on inhibition reveals inconsistencies across studies. Monitoring brain responses during the Flanker (used to measure inhibitory control) task may add valuable insight into the processes underlying group differences behaviorally, by studying the N200 and P300 event-related potentials which have been associated with inhibitory control processes. This study investigated whether there are differences between older and younger adults in inhibitory control and whether …

Pre-Stimulus Anticipation And Unconscious Fear Learning Disparities In Individuals With Varying Levels Of Anxiety, Anastasiya Rumyantseva Kharlamova

Dissertations, Theses, and Capstone Projects

The current study employed a Pavlovian conditioning paradigm to investigate the influence of pre-stimulus unconscious threat anticipation on subsequent fear responses in associative learning. Additionally, we explored the differences in pre-stimulus anticipation among individuals with varying levels of anxiety. Electrodermal response (EDA) was chosen as a primary measure due to its robustness in fear conditioning paradigms. Moreover, the State-Trait Anxiety Inventory (STAI) was utilized to assess anxiety levels in participants. Twenty-seven subjects were recruited to determine if pre-stimulus skin conductance responses (SCR) would exhibit stimulus-specific patterns influenced by implicit cues (L-shaped configurations) that indicated an upcoming face or a house …

Zoom Dysmorphia: An Eye-Tracking Study Of Self-View And Attention During Video Conferences, Kathleen H. Stimson May 2024

Zoom Dysmorphia: An Eye-Tracking Study Of Self-View And Attention During Video Conferences, Kathleen H. Stimson

Cognitive Science Senior Theses

This study investigates Zoom Dysmorphia, a heightened self-awareness and self-criticism of perceived physical flaws due to prolonged self-view on video conferencing platforms, with associated behaviors resembling symptoms of Body Dysmorphic Disorder (BDD). Drawing on Veale’s (2001, 2004) and Neziroglu’s (2004) cognitive-behavioral models of BDD and prior studies on BDD which suggest the development and maintenance of BDD through excessive self-focused attention and attentional bias, this study explores the potential cognitive and emotional implications of this phenomenon. Participants engaged in two mock video conferences with self-view enabled in one meeting and disabled the other for comparison. Eye tracking technology monitored their …
