The Role Of Prelimbic Projections To The Rostromedial Tegmnetal Nucleus In Cue Discrimination, Emma Lane Carlson

Theses and Dissertations

Maladaptive decision-making, such as persistent reward seeking despite negative consequences, is a hallmark of substance use disorder (SUD) and related psychiatric conditions. These behaviors are thought to arise from impairments in aversive learning and disrupted neural signaling that normally supports behavioral inhibition. The prelimbic cortex (PL) plays a critical role in encoding cue–outcome associations and exerting top-down control over behavior, while the rostromedial tegmental nucleus (RMTg) serves as a GABAergic inhibitor of midbrain dopamine neurons in response to aversive stimuli. Although both structures have been implicated in reward and avoidance processes, little is known about how direct PL-RMTg projections contribute …

Integrity On The Line: An Action Research Investigation Into Cheating Behaviors Among Honors Students, Latasha Arda Smart

Theses and Dissertations

Academic dishonesty remains a persistent issue in education, undermining both learning and institutional integrity. While it has been extensively researched in general contexts, little is known about its occurrence in high-achieving settings such as honors classes, where students are frequently under increased performance pressure. This action research study investigated the prevalence, causes, and consequences of cheating behaviors among honors students at a rural high school.

The Processing Of Emotional Prosody And Semantics In Native And Non-Native Chinese Speakers, Cheng Xiao

Theses and Dissertations

Emotional information in spoken language is conveyed through both semantic and prosodic cues. While listeners interpret the meaning of utterances (what is said), they also detect the speaker’s emotional prosody (how it is said). For non-native speakers, processing these two types of information simultaneously can be challenging, particularly in a tonal language such as Mandarin Chinese, where the same acoustic feature (i.e., pitch) encodes both lexical semantics and emotional prosody. This dissertation reports a series of behavioral and fMRI experiments investigating how native and non-native Chinese speakers perceive and process emotional prosody and semantics in words and sentences. Behaviorally, results …

Theses and Dissertations

This qualitative case study explored how teachers in Title I schools across the southern United States perceived and experienced school discipline practices. The study addressed the problem of inconsistent implementation of restorative and preventive frameworks, which has contributed to inequitable outcomes, teacher frustration, and lost instructional time. Although initiatives such as Positive Behavioral Interventions and Supports (PBIS) are mandated across many districts, inconsistent use and limited fidelity have restricted their effectiveness in improving equitable discipline and school climate.

The purpose of the study was to examine teacher perspectives to inform the development of a culturally responsive, schoolwide behavioral system grounded …

Anthropomorphism In Language And Thought: The Effect Of Agentive Linguistic Framing On Readers’ Perceptions Of Ai Animacy, Dawson Petersen

Theses and Dissertations

Over the past decade, deep learning AI systems have gone from academic obscurity to near cultural centrality in the developed world. As these technologies become increasingly integrated into daily life, there is growing cause for concern about AI anthropomorphism—i.e., the perception of AIs as more human than they really are. Despite the potential risks, AI developers continue to market their technologies using agentive language that seems to be designed to encourage anthropomorphism. The current dissertation utilizes behavioral and eye-tracking methods to examine the relationship between agentive linguistic framing and AI anthropomorphism in both controlled judgments and automatic inferences. The results …

Multi-Layer Decision Making For Long-Term Autonomous Mission Based On Dual Process Theory, Shruti Jadhav

Theses and Dissertations

Unmanned aerial vehicles (UAVs) are increasingly used in precision agriculture, where extended autonomous operation is required for monitoring, intervention, and field management. However, achieving long-term autonomy remains challenging due to battery constraints, environmental uncertainty, and the need to balance exploration with event-driven tasks. To address these challenges, a multi-layer decision-making framework inspired by Dual Process Theory (DPT) is developed. The framework combines reactive return-tobase strategies, exploratory navigation, and directional bias from prior missions, with a conflict-monitoring mechanism that adapts system behavior based on real-time conditions. The approach is implemented in a simulated agricultural grid environment, demonstrating improved adaptability and coverage …

Being both reviewers and recipients of feedback had positive yet distinct impacts on …

Unlocking The Power Of Connection: Engagement And Communication With Limited/ Non English Language Families, Melinda Hope Burnette

Theses and Dissertations

Family engagement can positively impact a student’s academic performance, attendance, literacy, and behavior at school (Bachman et al., 2021; Garbacz et al., 2018; Houri et al., 2019; Karge & Lansky, 2011; Robinson et al., 2022). However, there are several barriers to school-family communication, including additional responsibilities outside the school setting and socioeconomic factors. Parents and families who have limited/no English literacy skills face additional barriers to participation because of the lack of language support from schools in communicating events, providing access to language support at events, and parent perceptions of school acceptance (Arellanes et al., 2023; Perrigo et al., 2022; …

Too Much Of A Good Thing? Can Students Be Too Behaviorally Engaged, Rosemary Louise Odem

Theses and Dissertations

Student engagement in school is a key determinant of students’ academic success. Student engagement is commonly conceptualized as a meta construct comprised of three dimensions: emotional, cognitive, and behavioral engagement (Fredricks, 2015). Behavioral engagement, the focus of this study, is defined by positive conduct, involvement in learning and academic tasks, and participation in school-related activities (Fredricks et al., 2004). Some researchers have suggested that psychological strengths, like engagement, can be overused and result in maladaptive consequences (Niemiec, 2019; Oishi et al., 2007). This study addressed this notion using archival data from a sample of 422 students from one Southeastern US …

Strategies For Developing Mathematical Identities In Middle School Students, Margaret M. Stevens

Theses and Dissertations

This concurrent mixed-methods action research study investigated the impact of mathematical discourse intervention on seventh-grade students’ mathematical identities and understanding. Twenty students participated in a four-week intervention implementing Smith and Stein’s (2018) five practices plus one framework.

Quantitative results showed curriculum-based assessments improved significantly (p < .001, d = 1.64). State mathematics assessment revealed minimal change in mean scores. The Mathematical Identity Questionnaire revealed positive shifts across all five constructs, with largest gains in Mathematical Initiative (+0.40) and Problem-Solving Persistence (+0.30). Qualitative analysis using Bingham’s (2023) five-phase process revealed three themes: Mathematical Voice Development, Identity Transformation Through Competence Building, and Communal Validation. Social Cognitive Theory and Culturally Relevant Pedagogy integration showed how discourse interventions addressed both individual self-efficacy and systemic inequities. Findings suggest intensive discourse intervention can initiate positive changes in mathematical identity and understanding for struggling students. Implications include restructuring mathematics instruction to prioritize student discourse and voice, creating more equitable learning environments.

An Investigation Of Sex-Specific Effects Of Nucleus Accumbens Dopamine Receptor Signaling In Persistent Reward Seeking Under Punishment, Anna Caroline Toburen

Theses and Dissertations

Addiction involves persistent reward-seeking behavior despite adverse outcomes, with the nucleus accumbens (NAc) critically mediating motivation and cost-benefit decision-making. Dopamine (DA)-responsive neurons in the NAc, specifically D1 and D2 receptors within the NAc are crucial in encoding motivated behavior. However, the specific role of D1/D2 receptors in driving reward-seeking under punishment remains unclear. Preliminary findings suggest a sex-specific effect, with females exhibiting greater sensitivity to the suppressive effects of footshock on natural reward-seeking compared to males. We investigated the differential roles of NAc D1/D2 receptors in modulating reward-seeking behavior under punishment, with a focus on potential sex-specific effects. Using a …

Fuel represents over 70% of the logistical resupply demand within the Department of Defense, with the United States Air Force accounting for most of that consumption. While prior fuel efficiency efforts have primarily focused on technical upgrades, this research explores how behavioral interventions can influence pilot decision-making and operational energy outcomes. Using the Theory of Planned Behavior (TPB) as a guiding framework, this study investigates the effects of targeted behavioral strategies on pilots’ attitudes, subjective norms, perceived behavioral control, intentions, and actual fuel-efficient behaviors. A quasi-experimental design was applied through a controlled pilot study using simulator flights. Six participants were …

The Relationship Between Effort Cost Decision Making, Consummatory/Anticipatory Pleasure, And Health Behaviors In Schizotypy, Adriann Lai

Theses and Dissertations

Motivational and hedonic deficits are not well studied in schizotypy as they relate to health behaviors. Nonclinical undergraduate participants (n= 247) completed self-report measures and a behavioral task (EEfRT) that assessed effort cost decision making. Social anhedonia was positively associated with increased effort but simultaneously reduced responsiveness to increasing rewards, indicating inefficient effort allocation. Consummatory pleasure was the more relevant hedonic predictor of effort, rather than anticipatory pleasure. In exploratory analyses, higher positive schizotypy scores were significantly associated with greater consummatory pleasure, while disorganized schizotypy was unrelated to pleasure indices or effort performance. In secondary hypothesis analyses, all schizotypy traits …

Rethinking The Red Zone: Risk Factors Of College Student Dating Violence Victimization During The Fall Semester, Alexandra Nicoletti

Theses and Dissertations

College students experience dating violence (DV) victimization at alarmingly high rates, which is associated with a variety of negative outcomes (Brewer & Thomas, 2019; Choi et al., 2017; Leemis et al., 2022). To implement effective prevention programming, it is important to understand the risk factors associated with DV victimization on college campuses. Further, college students report the highest rates of one type of DV victimization—sexual victimization—during the fall semester, also known as the “red zone” (Carey et al., 2018, Cranney, 2015). This study utilized the socioecological model to understand which individual-, relationship-, and community-level risk factors were associated with DV …
