Unmasking Impression Management: Large Language Models For Detecting Socially Desirable Responding In Open-Ended Situational Judgment Tests, Barret Vermilion

Graduate Studies Theses and Dissertations 2026

Socially desirable responding (SDR) — the tendency to present oneself in an overly favorable light — remains a persistent validity concern in industrial-organizational psychology. Contemporary theory frames SDR as multidimensional, distinguishing agentic impression management (AM; inflating competence, dominance, and achievement) from communal impression management (CM; inflating warmth, cooperation, and prosocial qualities). Existing measures of AM and CM rely on self-report, which captures these constructs only at the level of generalized trait-like tendencies rather than as they naturally unfold in applicants' own language. This dissertation proposes a text-based alternative: detecting AM and CM in open-ended situational judgment tests (SJTs) of Big …

Switching Languages, Switching Personalities: The Socio-Cognitive Implications Of Bilingualism, Hannah F. Stern

Honors Undergraduate Theses

The increasing prevalence of bilingualism worldwide highlights the importance of further research into its impact on socio-cognitive processes. This study examines variations in personality traits, anxiety levels, locus of control, and cognitive load during language switching, utilizing cultural and visual-linguistic priming techniques to explore real-time socio-cognitive shifts across language contexts. A 2×3 mixed-factorial design compared language groups (monolingual vs. bilingual) across three priming conditions (semantic, cultural, and control). 120 participants completed a series of subjective and objective measures, including the Big Five Personality Inventory, Liebowitz Social Anxiety Scale, and Rotter’s I-E Scale in both languages, with controlled language-specific priming conditions …

Assessing Physiological Arousal During A Standard Versus Inverted Vigilance Task Using Heart Rate Variability, Taha Riaz

Honors Undergraduate Theses

Background: Vigilance tasks require sustained attention over long periods of time while monitoring for rare critical signals. Inverted or reverse vigilance/sustained attention response tasks (SART) may impose greater response-control demands. Although prior studies have compared these tasks behaviorally, there are fewer investigations examining whether they differ in physiological arousal as indexed by heart rate variability (HRV).

Method: Undergraduate students from UCF completed a variation of either the X-CPT (standard vigilance task) or the CPT-3 (inverted/SART) task. Electrocardiogram data was recorded continuously. Data from 40 participants were analyzed. HRV was indexed using frequency domain analysis using the low-frequency to high-frequency ratio …

Investigating The Relationship Between Metacognition And False Feedback, Sarah M. Grillo

Honors Undergraduate Theses

Accepting false feedback may lead to performance decreases and skewed confidence. Identifying who is more susceptible to false feedback can help us understand how to prevent performance declines and overconfidence. We believe that individuals with low metacognition may be more susceptible to blindly accepting false feedback because they often rely on external sources of feedback for self-evaluation, whereas high metacognitive individuals may be protected because they often rely on accurate internal judgements for self-evaluation. Feedback is important for successful task execution; it can highlight errors (negative feedback) or successful behaviors (positive feedback) to guide future behavior. Individuals with higher metacognition …

A Modular Virtual Reality Training Framework For Multi-Target Drone Defense, Susann Schleupner

Graduate Studies Theses and Dissertations 2026

Unmanned aerial systems (UAS), commonly referred to as drones, have become a rapidly growing challenge in modern military operations. In particular, the increasing use of small, agile, and low-cost systems—such as first-person-view (FPV) drones and coordinated multi-drone deployments—places high cognitive demands on operators, requiring rapid target detection, prioritization, and decision-making under time pressure.

Existing training approaches either rely on costly and logistically constrained live exercises or focus primarily on isolated piloting and shooting tasks, without sufficiently addressing these cognitive demands. At the same time, advances in commercial off-the-shelf (COTS) virtual reality (VR) hardware enable scalable, flexible, and repeatable training environments. …

Careless Responding: Testing The Theory Of Vigilance, Rusty Wilson

Graduate Studies Theses and Dissertations 2026

Careless responding (CR) has been identified as a threat to the psychometric integrity of cognitive and non-cognitive tests, with much of the current research focusing on the identification and removal of carelessness from dataset. While this research has proved fruitful in improving data quality, there has been a recent push to move towards preventing carelessness as opposed to post-hoc removal, which harms statistical power. However, the most common prevention strategy to prevent carelessness (pre-survey warnings) has shown equivocal effects. Additionally, the literature lacks an agreed upon theory to explain why carelessness occurs. To address these gaps I introduce theory from …

Gaining Voice, Creating Opportunity: An Exploration Of Non-Native English-Speaking Students’ Sources Of Self-Efficacy In U.S. College Public Speaking Classrooms, Desiree M M Flores-Molina

Graduate Studies Theses and Dissertations 2026

This qualitative dissertation explores the sources of public speaking self-efficacy among non-native English-speaking international students enrolled in U.S. college public speaking courses. The study applies Bandura's social cognitive theory to examine how students describe the experiences that shape their confidence and perceived ability to succeed, with attention to mastery experiences, vicarious experiences, verbal persuasion, and physiological and affective states. It also considers how classroom practices and instructor support contribute to or constrain students' confidence.

Data were collected through semi-structured student interviews, guided reflection artifacts connected to major speech assignments, and key-informant interviews with public speaking instructors. Thematic analysis was used …

Comparing Interactive Versus Static Educational Images On Student Learning Outcomes, Noah Schwartz

Honors Undergraduate Theses

Static images routinely accompany text in educational sources such as textbooks, articles, and websites to convey complex, educational information. These are generally effective; however, current technology allows for interactive images that seem to enhance engagement. How effective are these interactive images? The present study investigated whether an interactive image produced better learning outcomes compared to a static image using the same text. Specifically, this study examined whether interactive images affected comprehension, memory, engagement, and cognitive load differently than static images. In this study, data from 153 college student participants were analyzed. First, participants were assigned to read about the neuropsychology …

From Vinyl To Viral: Evaluating The Mere Exposure Effect Through Music And Technological Advancements, Ariana R. Deboo

Honors Undergraduate Theses

The Mere Exposure Effect (MEE) refers to a psychological pattern in which a person develops preference for a stimulus that has been repeatedly presented to them. The present study examined environmental influences of preference through repeated exposure to music. Social media platforms such as TikTok, Reels, and Shorts influence where people listen to music. The fast-paced consumption algorithm for new media is provided by quick, entertaining videos that allow users to scroll past content that does not keep their attention. A total of 406 participants (n=406) were involved in this study. The purpose for this study was to identify how …

Users' Trust Perceptions Of Ai Search Results, Leilani J. Cordoves

Honors Undergraduate Theses

Utilizing a repeated measure design, this experiment analyzes users’ perceptions of artificial intelligence embedded within search engines compared to traditional linked search engines in various contextual situations. The purpose of this study is to find the differences in confidence for differing search methods and the variables of trust that lead to these perceived differences. Using screenshots of AI overview search results and linked search results, we asked participants questions of confidence and human-computer trust to gauge their perceptions of the varying search methods. We find evidence of a significant interaction effect in confidence scores between the search method and the …

Investigating The Effects Of Binaural Beats On Encoding Efficiency And Working Memory Performance In College Students With Attention-Deficit/Hyperactivity Disorder Traits, Megan Daza

Honors Undergraduate Theses

Binaural beats (BB) have been increasingly explored as a non-invasive cognitive enhancement tool, particularly in populations with neurodevelopmental conditions such as Attention-Deficit/Hyperactivity Disorder (ADHD). This study investigates the effects of beta-frequency binaural beats on encoding efficiency and working memory performance, specifically verbal-spatial working memory, in college students with ADHD traits. Using a 2 (ADHD/Neurotypical) × 2 (Low/High Cognitive Load) mixed ANOVA design, participants will complete an N-back working memory task under baseline, binaural beats, and control (white noise) conditions. Key research questions examine whether binaural beats improve working memory accuracy and reaction time, whether their effects vary across cognitive load …

Disconnected Minds: Exploring Nomophobia And Adhd's Impacts On Driving Hazard Perceptions Among College Students, Stephanie Zheng

Honors Undergraduate Theses

An increasing psychological concern in the 21st century is the development of the fear of being unable to access one's mobile phone, also known as nomophobia. However, its impact on individuals with Attention-Deficit/Hyperactivity Disorder (ADHD) remains largely unexplored. Given ADHD’s association with impulsivity, attentional difficulties, and emotional dysregulation, those with the condition may be particularly vulnerable to nomophobia, which can affect every aspect of their daily lives, ranging from interpersonal relationships to their academic success and overall physical and mental well-being. This study aims to answer four questions: how does ADHD impact the severity of nomophobia among college students, do …

In Seal We Trust? Investigating The Effect Of Certifications On Perceived Trustworthiness Of Ai Systems, Magdalena Wischnewski, Nicole Krämer, Christian Janiesch, Emmanuel Müller, Theodor Schnitzler, Carina Newen

Human-Machine Communication

Trust certification through so-called trust seals is a common strategy to help users ascertain the trustworthiness of a system. In this study, we examined trust seals for AI systems from two perspectives: (1) In a pre-registered online study participants, we asked whether trust seals can increase user trust in AI systems, and (2) qualitatively, we investigated what participants expect from such AI seals of trust. Our results indicate mixed support for the use of AI seals. While trust seals generally did not affect the participants’ trust, their trust in the AI system increased if they trusted the seal-issuing institution. Moreover, …

Human Performance In Context: Exploring The Effect Of Social Support On Vigilance, Allison E. Garibaldi

Graduate Thesis and Dissertation 2023-2024

Over many decades, vigilance research has consistently found that performance on vigilance tasks decline over time (i.e., the vigilance decrement; Davies & Parasuraman, 1982), and that performing a vigilance task is both mentally demanding and stressful (Warm et al., 2008). Researchers have subsequently implemented a wide range of interventions to both understand and attempt to attenuate the vigilance decrement and its associated affective effects. Among these efforts, little attention has been devoted to understanding the effects of the social environment on vigilance. Nonetheless, a handful of studies have indeed suggested that the presence of others can affect performance, workload, and …

Deceptive Realities: Exploring The Nexus Of Fake News, Artificial Intelligence, And Public Perception, Victor E. Milanes

Honors Undergraduate Theses

Our research delves into two critical areas: fake news and artificial intelligence (AI). Historically, fake news predates the printing press, but its resurgence after the 2016 US Presidential Election garnered mass attention. Studies indicate its potency, with one fake article found to be as influential as a campaign ad (Allcott & Gentzkow, 2017). However, partisan media likely skews its impact on public perception.

Conversely, AI's integration has surged in recent years, sparking both excitement and concern among the public (Pew Research Center, 2022). Its ability to generate hyper-specific images, demonstrated by DALL·E 2 and Midjourney, poses challenges in distinguishing real …

Learning Disabilities And The Impact Of Accommodation Programs In Post-Secondary Education, Jacqueline Persaud

Honors Undergraduate Theses

As enrollment rates for students with learning disabilities steadily increase, post-secondary institutions must become more inclusive. Current literature reveals a gap in studies between post-secondary education and student views on access programs. Our endeavor focused on this community. The survey was distributed using SONA and by the Student Accessibility Services Office via Qualtrics. Our study looked at 312 participants, aged from 18 - over 30 years old and who varied in sex. More satisfaction with accommodations equated to more academic competence towards goals. However, the results showed less satisfaction with personal lives and self-acceptance. This is possibly due to participants …

Revisiting The Vigilance Taxonomy: Are Findings Consistent In A Remote Environment?, Grace E. Waldfogle

Graduate Thesis and Dissertation 2023-2024

Previous research has highlighted key taxonomic factors that have been found to influence human performance on vigilance tasks. However, previous literature has focused on research conducted in laboratory settings but has not examined vigilance tasks in remote environments. The present dissertation addresses this gap in the literature by examining human performance on a remote vigilance task, as well as workload and stress associated with the task. Qualitative data were collected to further understand the environment and distractions that participants experienced. Across three experiments, 372 participants were asked to complete a vigilance task and answer surveys pertaining to stress, workload, and …

Neural Dynamics Of Categorical Representations Used For Visual Search, Ashley Phelps

Electronic Theses and Dissertations, 2020-2023

Decades of visual attention research have predominantly used pictorial search paradigms that cue participants with the exact perceptual details of the target. However, in everyday life, people often search for categories rather than specific items (i.e., any pen rather than a specific pen). To study visual attention in a more realistic context, researchers can use categorical search paradigms that cue participants with text indicating the target category. In these instances, one must rely on long-term memory to retrieve categorical features of the target. Both experiments in this study were a reanalysis of experiments previously designed and collected by Schmidt and …

Locating The Attentional Template Using Theta-Gamma Coupling, Michael Miuccio

Electronic Theses and Dissertations, 2020-2023

A significant amount of research has investigated the underlying neural mechanisms that enable the direction of attention throughout a search array. The biased competition model (Desimone & Duncan, 1995) proposes that an attentional template (the neural instantiation of the search target) is created when the target representation in visual working memory (VWM) is communicated to frontal regions which then bias early visual areas to attend to target features. Despite this, much of the current work focuses solely on the target representation in VWM, which is only one small part of the attentional template according to biased competition. Thus, I used …

Gamification Of Sleep Hygiene Education For Insomnia: An Examination Of Its Efficacy And The Role Of Individual Differences, Christine Seaver

Electronic Theses and Dissertations, 2020-2023

Insomnia is a sleep disorder which is classified by one's persistent inability to fall asleep or maintain sleep. One common yet controversial approach to treating insomnia is sleep hygiene education (SHE). Sleep hygiene is defined as behaviors that promote quality sleep. SHE is typically provided through as a paper sheet containing a list of recommendations, and the findings regarding its efficacy are mixed. Providing insomnia sufferers with a SHE treatment modality that offers practice, feedback, and motivation may be effective at treating insomnia. Therefore, the first goal of the present study is to examine the efficacy of a game-based SHE …

Automation, Take The Wheel: An Examination Of Factors Influencing Trust In Automated Driver Assist Technologies, James Ferraro

Electronic Theses and Dissertations, 2020-2023

Driving technology has progressed significantly since the introduction of anti-lock braking and cruise control decades ago. Current driver assist features can alert drivers of oncoming vehicles and even take control to keep the vehicle centered within its lane. The level of trust that people place in automation can impact how they monitor and accept these automated systems. Previous research has shown several performance outcomes associated with improper calibrations of trust in automation. However, there is still a need to examine trust in the context of advanced driving technologies. Research has yet to sufficiently investigate factors influencing trust in assistive driving …

Investigation Of Realism In Facial Characteristics And Anthropomorphic Language In The Design Of Multimedia Instruction, Ecem Olcum

Electronic Theses and Dissertations, 2020-2023

Emotional design elements have recently been added to the research in cognitive load and multimedia learning (Um et al., 2012). One aspect of eliciting positive emotions is to use anthropomorphic design, which has been found to increase learning performance (Um et al., 2012; Plass et al., 2014; Park et al., 2015; Schneider et al., 2018). The current research aimed to investigate three design factors in three studies: anthropomorphism in verbal and visual design, single-frame or multi-frame illustrations, and realism of the anthropomorphic visual design. The first study confirmed that the anthropomorphic verbal and visual materials were perceived as anthropomorphic by …

Predictors Of Technology Use Among Older Adults: Evidence Ranging From Non-Users To Elite Users, Xiaoqing Wan

Electronic Theses and Dissertations, 2020-2023

Older adults tend to under-utilize digital technology and online services that can yield substantial benefits to their health and wellbeing. Addressing this problem requires determining robust and consistent predictors of older adults' technology use. Also, few studies have examined older adults who are elite users of digital technology, who may provide insights into how individuals can prepare to become competent users of future technologies as they age. To address these gaps in the technology and aging literature, this dissertation offers (1) large-scale machine learning analyses, (2) longitudinal perspectives, (3) age group comparisons across the adult life span, (4) the novel …

Modeling The Relationship Between Perceptual And Stimulus Space In Category Learning, Clay Killingsworth

Electronic Theses and Dissertations, 2020-2023

Learning to categorize visual stimuli is a fundamental cognitive skill underlying both everyday functioning and professional competencies in domains such as radiology and airport security screening. Categories may be very simple or highly complex, with accurate categorization dependent on multiple interacting features. General recognition theory (GRT) models uniquely allow examination of feature dimension interactions, but basic questions remain about the applicability of such models and the 2x2 categorization tasks (four-alternative forced choice) employed in studies which use them. Findings in several studies that factorially combine 2 levels of 2 stimulus dimensions indicate a common pattern of perceptual advantage for the …

Out With The Humans, In With The Machines?: Investigating The Behavioral And Psychological Effects Of Replacing Human Advisors With A Machine, Andrew Prahl, Lyn Van Swol

Human-Machine Communication

This study investigates the effects of task demonstrability and replacing a human advisor with a machine advisor. Outcome measures include advice-utilization (trust), the perception of advisors, and decision-maker emotions. Participants were randomly assigned to make a series of forecasts dealing with either humanitarian planning (low demonstrability) or management (high demonstrability). Participants received advice from either a machine advisor only, a human advisor only, or their advisor was replaced with the other type of advisor (human/machine) midway through the experiment. Decision-makers rated human advisors as more expert, more useful, and more similar. Perception effects were strongest when a human advisor was …

Investigating The Role Of Trust And Self-Confidence In Automation, Daniela R. Miele

Honors Undergraduate Theses

A proper calibration of trust in automation is imperative to achieve optimal overall performance in human-machine systems. Previous research has suggested that human operator trust could be influenced by various situational and dispositional factors, as well as operator self-confidence. It is critical to examine what traits and factors will influence how likely a person is to trust autonomous vehicles as they become more prevalent on today's roadways. The goal of this study was to further examine the relationship between individuals' level of self-confidence in their own driving abilities and their reported trust in automation when driving semi-autonomous cars. It was …

Comparative Examination Of The Empatica E4 To Record Heart Rate Variability Metrics, Andres Rosero

Honors Undergraduate Theses

The increased accessibility of cyber technology has resulted in advancements in international communications and information sharing never seen in human history. With this new age of digital software comes the proliferation of illegal online activity and cyber terrorism. Repercussions of cyber-attacks have ranged from identity theft to leaks of classified state secrets. To combat this threat, the Department of Defense (DoD) established the Cyber Mission Force (CMF) to head operations in the interests of protecting against cyber-attacks. One of the CMF’s initial projects involves the creation of a Performance Assessment Suite (PAS), a training program designed to improve the training …

Determining And Assessing Fault Attribution In Collisions Involving Autonomous Vehicles, Alexandra Kaplan

Electronic Theses and Dissertations, 2020-2023

There exists considerable research concerning how humans attribute fault to each other, both in cases of accidents and those instances of intentional harm. There also exist studies involving blame attribution towards robots, when such robots have caused harm through operational failure or lack of safety features. However, relatively little work has, to date, examined the ways in which fault is attributed to self-driving vehicles involved in collisions, despite many newspaper and popular articles which both report past incidents and warn of future risk. This dissertation examined fault attribution in collisions involving autonomous vehicles by conducting three separate experiments. The first …

Does One Bad Phish Spoil The Whole Email Load?: Exploring Phishing Susceptibility Task Factors And Potential Interventions, Dawn Sarno

Electronic Theses and Dissertations, 2020-2023

Phishing emails have become a prevalent cybersecurity threat for the modern email user. Research attempting to understand how users are susceptible to phishing attacks has been limited and hasn't fully explored how task factors influence accurate detection. Even further lacking are the existing training interventions that still have users falling victim to up to 90% of phishing emails following training. The present studies examined how task factors (e.g., email load, phishing prevalence) and a new form of intervention, rather than training, influence email performance. In four experiments, participants classified emails as either legitimate or not legitimate and reported on a …

The Effects Of Social Conformity In Human-Robot Interaction, William Volante

Electronic Theses and Dissertations, 2020-2023

While previous work has investigated aspects of the robot, the human, and the environment as influential factors in the human-robot relationship, little work has examined the role of social conformity in this relationship. As social conformity has been shown to affect human-human choice, relationships, and trust, there are a-priori reasons to believe that it will play an influential role in human-robot interaction (HRI) scenarios as well. Early research into the influence of social conformity in human-robot interaction (HRI) did not find the effect to be present with robots, however more recent work has adapted the methodological paradigm to find more …
