Brief Treatment For Ptsd: Promoting Trauma Recovery With A Five-Session Cognitive Processing Therapy Protocol, Sanela Kalakovic

Dissertations

Cognitive Processing Therapy (CPT) is a first-line treatment for trauma. CPT is traditionally administered over 12 sessions. This open clinical trial examined the feasibility and efficacy of a 5-session CPT protocol. The abbreviated protocol moves more quickly to the proposed therapeutic mechanism of action, cognitive restructuring, to alter unhelpful traumarelated thoughts and beliefs. The goal is to maintain efficacy while making therapy more efficient and thereby reducing barriers to trauma treatment. Using a repeated measures open clinical trial design (with embedded multiple baselines), 67 adults (M age = 43 years, 90% female, 79% White) with clinically significant post-traumatic stress disorder …

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 …

Unpacking The Behavioral, Cognitive, Sleep, And Stress Associations With Smartphone Checking, Yi Jing Chua

Dissertations and Theses Collection (Open Access)

The widespread use of smartphones for various daily activities has led many users to habitually check their devices. Smartphone checking may be negatively associated with daily behavioural, health, affective, and cognitive outcomes when it interrupts individuals during their work, health, and well-being-enhancing pursuits. Yet, research on smartphone checking suffers from various research gaps, including the use of cross-sectional design which hinder interpretation of the direction of relationship between smartphone checking and daily outcomes, the presence of individual difference confounds, and relying on subjective smartphone checking measures that are susceptible to recall biases. To address these gaps, the study investigated the …

A Daily Diary Investigation Of The Fear Of Missing Out And Diminishing Daily Emotional Well-Being: The Moderating Role Of Cognitive Reappraisal, Andree Hartanto, Joax Wong, Verity Yu Qing Lua, Yue Qi Germaine Tng, K. T. A. Sandeeshwara Kasturiratna, Nadyanna M. Majeed

Research Collection School of Social Sciences

With modern societies becoming ever-increasingly interconnected due to technology and media, we have gained unprecedented access and exposure to other people’s lives. This has resulted in a greater desire to constantly be socially connected with the activities of others, or the fear of missing out (FoMO). While much of the present available research has established the association between FoMO and diminished emotional well-being, little has been done to identify protective factors that can help one cope with the negative psychological consequences of FoMO. Utilizing data from a 7-day diary study of a large sample of young adults (N = 261), …

Ripl: Recursive Inference For Policy Learning, Kunal Jha, Jeremy R. Manning, Alberto Quattrini Li

Computer Science Senior Theses

Humans excel at understanding the thoughts and intentions of others (theory of mind) and leverage this ability to learn and adapt in social environments. However, replicating this capability in artificial agents remains a challenge. This paper explores the gap between fast, efficient learning often achieved by Reinforcement Learning (RL) algorithms and the interpretability and adaptability desired in agents interacting with humans. We propose a novel approach that integrates an inference network within existing RL frameworks. This allows agents to reason about the beliefs of others (nested reasoning) while learning optimal actions. Our method leverages approximate solutions to the I-POMDP framework, …

Consciousness And The Reality Of Monsters In Horror Movies: Dehumanization And What Monsters In Horror Films Say About Us, Leila Kincaid

Journal of Conscious Evolution

This essay responds to Carroll’s The Nature of Horror from the perspective of transdisciplinary phenomenological film theory, largely developed by Edgar Morin in the 1950s. It argues that Carrolls’s reduction of the phenomenological value of horror films to an unreal category minimizes and even dismisses the inherent value of horror films. Morin, Allan Combs, and others offer more integral and transdisciplinary methods for art interpretation and functionality. They help us understand how monsters in horror films can stand as mirrors and reflections of the monstrous in ourselves and society. Thus, the transformational function and value of film is revealed and …

Understanding Parasocial Relationships And The Mental Health Impact, Leslee Lynae Bennett

Master's Theses

Parasocial relationships have recently become a topic of discussion in our society. This is because individuals are still looking for something to connect with after the COVID-19 pandemic. These relationships originally were more common among young people, but due to the constant usage of media, individuals have become more attached to popularity which results in an unrealistic online connection. Parasocial relationships are both a fascination and a danger due to the mental connections an individual makes within themselves. This research is a qualitative study of previous research done on parasocial relationships. Topics discussed in this thesis will cover multiple facets …

Listener Biases Toward Chinese And Latino Instructor Accents: Their Impact On Subjective Evaluations And Objective Memory Measures, Ka Wai Lau

Student Theses and Dissertations

Many people in the United States speak with a non-native accent that reveals their racial identity. Accent bias and discrimination are prevalent issues in many social interactions, including academic and work environments. Past research has argued that foreign-accented speech is generally more difficult to process. The present study aimed to explore the impact of Chinese and Latino accents compared to standard American accents on subjective evaluations and objective memory in a classroom setting. Participants were asked to evaluate speaker competence, trustworthiness, and warmth in math and Western literature lessons and completed a memory test for them. I found that Chinese-accented …

The Power Of Words: Unpacking Language's Role In Educational Inequities, Zara Yokohama, Liz Beccari, Malcolm Jasmin

Symposium Of University Research and Creative Expression (SOURCE)

The language used to describe racial disparities in education may inadvertently influence how we address them. Framing such disparities as “achievement gap” rather than as “inequality in educational outcomes” assumes a deficit thinking mindset, shifting focus from the structural injustices contributing to education disparities to individuals, resulting in decreased prioritization of racial equity (Quinn & Desruisseaux, 2022). We aim to replicate this prioritization effect, specify the language driving the effect, and examine the impact of frames on perceptions of how to achieve racial equity. Participants were randomly assigned to conditions framing racial equity concerns as: a racial achievement gap, racial …

Comparing Executive Control: Bilingualism's Cognitive Advantage, Malcolm Jasmin, Tonya Buchanan Ph.D.

Symposium Of University Research and Creative Expression (SOURCE)

The Stroop Task is a widely used method for studying executive control. It helps to understand cognitive processes like inhibition and attentional regulation to examine how reading text and naming colors can interfere with each other. The study intends to use the Stroop Task to explore the executive control abilities of both bilingual and monolingual individuals. Previous research has shown that bilingual individuals perform better in the Stroop test compared to those who only speak one language (Bialystok et al., 2010). The impact of this advantage is believed to be due to the need to switch between languages and prevent …

The Relationship Between Autistic Traits, Autistic Camouflaging, And Adults’ Representations Of Abstract And Social Concepts, Henry Tomiser, Katja Wiemer Dr.

Honors Capstones

Concrete concepts (e.g., BUTTON) can be experienced directly by the senses, whereas abstract concepts (e.g., FRIENDSHIP) cannot. Additionally, the mind may represent abstract concepts using more introspective, social, and emotional information than concrete concepts. Social difficulties are one defining feature of autism, and autistic individuals may use social camouflaging to hide these difficulties, but the precise nature of social processing in autism is not known. This study aims to explore possible links between autistic traits, autistic camouflaging, and mental representations of concepts. Participants gave open-ended definitions for concepts varying in concreteness and social content via an online survey. Responses were …

The Effects Of Classification Versus Observation During Category Learning, Enoch Sarakpo

Theses - ALL

We report a category-learning experiment that examines the learning outcomes of classification and observational training methods across three category structures. Thus, we crossed training (classification vs. observation) and category type (natural vs. featural vs. relational). Some subjects classified the stimuli (side-by-side bird pairs) and received corrective feedback after each response, whereas others studied these stimuli, wherein they were presented with the corresponding category label. The posttest was an endorsement task made up of repeated and novel items. We did find an observation training advantage, as subjects in the observation training were better in the natural and relational categories for the …

Contextual And Positional Associations In Free And Serial Recall, Nathan Burns

Theses - ALL

The research in this thesis presents a novel experiment and analyses to characterize effects in episodic memory which have classically been developed using different classes of theories. An encoding design was used which typically offers support for positional coding theory, phonological similarity among words in a studied list, with a recall paradigm which typically offers support for retrieved context theory, free recall. This experiment manipulated recall task, serial recall and free recall, as well as the presence and order of similar items across three possible list types. Analyses focused on differences in recall probability, recall errors, and recall transitions by …

The Effects Of Processing Tasks On False Memories, Caroline Lewis

Honors Theses

The purpose of the present study was to examine the effects that three different processing tasks had on the rate of false memories. Participants were randomly assigned into a story condition, survival condition, or a pleasantness condition. Using a word list that had three groups of ten words each connected to a nonpresented critical word, participants were asked to process the words using instructions based on their given condition. Processing occurred through written sentences, which was then followed by a short mathematical distraction test. Participants were then given time to recall all of the words presented on the list by …

Sleep's Relationship To Executive Functioning In Toddlers, Ella Havertape

Honors Theses

The primary purpose of this study was to identify the relationship between toddlers’ sleep and executive functioning. While there are a few studies that examine the relation between sleep and executive functioning in this age group, the majority of research focuses on older populations. Regardless, previous research has found a correlation between sleep problems and executive functioning abilities. This study utilized a parent reported questionnaire to measure children’s sleep and a battery of tasks to measure executive functioning. The results revealed no correlation between sleep duration and executive function performance, however, I did find a correlation between night wakefulness and …

Predicting Personal Growth: An Analysis Of Self-Relevant Approaches, Cole Morse

Honors Theses

Identifying predictors of personal growth–defined as striving to fulfill one’s unique potential–may be important for achieving a life of flourishing (Ryff & Singer, 2008). While existing research demonstrates the link between self-esteem and personal growth, gaps remain in our knowledge of the relationship between other potential self-referential predictors and personal growth (Paradise & Kernis, 2002). The intention of the current study is to not only conceptually replicate the link between positive self-regard (i.e., a positive self-evaluation that is theoretically akin to self-esteem) and personal growth, but to also investigate whether different ways of relating to the self offer unique pathways …

Companionship, Romance, And Self-Perception With Conversational Chatbots, Jonathan Windsor

Departmental Honors & Graduate Capstone Projects

Serving as a metaphorical gateway transcending the communicative barriers of physical relationships in interpersonal dialogues, artificial imators of human behavior and speech, also known as conversational chatbots; a simulation of human knowledge and existence in a bi-directional conversation, functions as a rhetor of expression. Spanning from contexts of professional to romantic, I serve to dissect and critically analyze the nuances of human-machine relationships based on pre-established literature, inviting ethical considerations and biases in their design and marketing. Corporate influences spark pre-established servitude-esque relationships with conversational agents. Professional applications, both task-oriented and emotionally based alike, paint a mixed picture of …

The Impact Of Perceived Self-Connection On Possession-Based Placebo Analgesia : An Investigation Using Implicit And Explicit Measures, Sze Ki Ng

Lingnan Theses (MPhil & PhD)

Previous study found merely possessing a placebo analgesic cream (without using) has similar pain outcomes when it is compared with using a placebo analgesic cream, but the underlying mechanism is unclear (Yeung et al., 2019). Yeung et al. (2020) proposed that an object-to-self expectancy can be a possible mechanism underlying a possession-based placebo effect, which means people believe that the owned object will benefit them. The present study aimed to examine this hypothetical mechanism and investigate how forming a cognitive connection between the analgesic cream and the self affects the possession-based placebo effect. We demonstrated the effect existed and observed …

The Effects Of Acute Exercise On Retrieval-Induced Forgetting, Anna Katherine Pitts

Honors Theses

This research investigates the relationship between acute exercise on retrieval-induced forgetting. Retrieval-induced forgetting (RIF) is a type of active forgetting that occurs when recalling an item from memory leads to the concurrent forgetting of related items connected to the same memory. Inhibition has been theorized as a potential mechanism behind RIF. Additionally, previous studies have shown that acute exercise can contribute to and enhance cognitive inhibitory processes. Therefore, an exercise-RIF relationship is plausible because the mechanisms that influence RIF, inhibition, are also influenced by exercise. Due to this understanding, the present thesis aims to investigate that when acute vigorous-intensity exercise …

Relations Between Parent Reports Of Effortful Control And Behavioral Measures Of Executive Function In Toddlers, Racheal Embry

Honors Theses

Recent proposals have identified many commonalities in conceptualizations of effortful control and executive function (EF, e.g., Zhou, Chen, & Main, 2012). However, the overlap of effortful control and EF during periods of emerging regulation in toddlerhood has not been thoroughly investigated. In the present study, I examined the relationship between effortful control and EF in 14, 18, and 24 month old toddlers by a combination of in-lab tasks and parent report measures. Results revealed few relations between effortful control and EF during this time. The lack of overlap between effortful control and EF may be explained by a number of …

The Effects Of Vigorous-Intensity Acute Exercise On Hippocampal- And Prefrontal Cortex-Dependent Memory, Lauren Hord

Honors Theses

Acute exercise has been shown to differentially impact memory, dependent on whether the task is considered prefrontal cortex- or hippocampal-dependent. More specifically, acute exercise has been shown to impair PFC-dependent memory while enhancing hippocampal-dependent memory. No study has compared whether exercise differentially impacts separate types of cognition, so this experiment was designed to determine the relationship between high-intensity acute exercise and both prefrontal cortex-dependent and hippocampal-dependent memory. This study consisted of five total visits for 55 participants. In the first visit, participants engaged in a maximal exercise test, where their heart rate reserve was obtained. In visits 2-5, participants engaged …

Trust Judgements Of Facial Stimuli, Linsey Culkins

Dissertations, Theses, and Projects

Professional counselors and clients who meet in healthcare facilities may be required to wear masks if COVID community transmission levels are high ([CDC], 2022). The current 4-part study examines how masking may affect therapeutic alliances via judgements of trust formed during first impressions. A 2(trustworthiness) x 5(facial feature visibility) within-subjects factorial design was used to assess one implicit measure of pleasantness using an Affect Misattribution Procedure as well as explicit facial judgements of valence, dominance, and trustworthiness (Payne & Lundberg, 2014). Using E-prime, undergraduate psychology students responded to faces previously rated as high or low in trustworthiness in all parts …

Improving Ethics Surrounding Collegiate-Level Hacking Education: Recommended Implementation Plan & Affiliation With Peer-Led Initiatives, Shannon Morgan, Dr. Sanjay Goel

Military Cyber Affairs

Cybersecurity has become a pertinent concern, as novel technological innovations create opportunities for threat actors to exfiltrate sensitive data. To meet the demand for professionals in the workforce, universities have ramped up their academic offerings to provide a broad range of cyber-related programs (e.g., cybersecurity, informatics, information technology, digital forensics, computer science, & engineering). As the tactics, techniques, and procedures (TTPs) of hackers evolve, the knowledge and skillset required to be an effective cybersecurity professional have escalated accordingly. Therefore, it is critical to train cyber students both technically and theoretically to actively combat cyber criminals and protect the confidentiality, integrity, …

Using Digital Twins To Protect Biomanufacturing From Cyberattacks, Brenden Fraser-Hevlin, Alec W. Schuler, B. Arda Gozen, Bernard J. Van Wie

Military Cyber Affairs

Understanding of the intersection of cyber vulnerabilities and bioprocess regulation is critical with the rise of artificial intelligence and machine learning in manufacturing. We detail a case study in which we model cyberattacks on network-mediated signals from a novel bioreactor, where it is important to control medium feed rates to maintain cell proliferation. We use a digital twin counterpart reactor to compare glucose and oxygen sensor signals from the bioreactor to predictions from a kinetic growth model, allowing discernment of faulty sensors from hacked signals. Our results demonstrate a successful biomanufacturing cyberattack detection system based on fundamental process control principles.

Emotional And Metacognitive Impacts Of A Human Anatomy Course Utilizing Three-Dimensional Learning Modalities, Shawn M. Magrum

Theses & Dissertations

A high school human anatomy course was designed to integrate three-dimensional learning modalities through the use of three-dimensional visualization technology, augmented reality, and whole-body donors (cadaveric specimens), and customized 3D digital models were created to support student learning. The course was organized so that each class meeting fell into one of six unique learning session types: lectures, augmented reality labs, gross anatomy (cadaveric) labs, content application (active learning) sessions, review sessions, and examination sessions.

An interval scale using ten emoji, each associated with a particular emotional valence (i.e., pleasantness) level, was developed and integrated into the course to track students’ …

The Relationship Between Amygdala And Orbitofrontal Cortex Volume In The Context Of Oppositional Defiant Disorder, Rahul Alla

Honors Scholar Theses

Disobedient and rebellious attitude in children is on the rise and this type of behavior is categorized as Oppositional Defiant Disorder (ODD). ODD in children can be identified as a persistent pattern of angry or irritable mood, argumentative or defiant behavior or vindictiveness toward others according to the Diagnostic and Statistical Manual (DSM-5, Fifth Edition) of Mental Disorders.1 Children with ODD typically have difficulty regulating and processing their emotions. Issues with regulating emotions is defined as the process by which individuals “influence which emotions they have, when they have them, and how they experience and express them”.2 Dysregulation of emotions …

Implementing The Reconsolidation Paradigm In Treating Misophonia, Angel Prats

Theses and Dissertations

Misophonic patients experience extreme sense of disgust when exposed to acoustic and/or visual triggers. In this longitudinal study, the reconsolidation paradigm was applied to treat 25 patients during a month. The findings reveal that reminders in a control setting did not improve maladaptive memories, but counterconditioning update ameliorated symptoms.

Conceptual Representation And Schemas: Perceived Gender Differences Among Kinds And Shared Properties, Kathryn G. Johnson

Theses and Dissertations

Schemas are modes of categorization containing associations between kinds and their related properties. Research suggests sex-linked properties possess principled differences between the sexes. The present study’s results suggest that non-sex-linked properties also possess principled differences, which were more prevalent among properties with principled rather than causal connections to a kind.
