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 …

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 …

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 …

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 …
