Physiological Response To Concealed Information In A Mock-Crime Paradigm​, Ezra Koenigsberg, Tamya Mchenry, Jasmine Manzana, Taylor Powell, Samantha Jackson

Science University Research Symposium (SURS)

The Concealed Information Test (CIT), based on Lykken’s guilty knowledge framework, measures physiological responses when individuals recognize crime-related details compared to neutral alternatives. Previous studies show that variations in stimulus presentation enhance the CIT’s accuracy, especially through changes in electrodermal activity and heart rate. However, few studies have tested whether a Qualtrics-based mock-crime version of the CIT can replicate these physiological patterns. This study addresses that gap by adapting the CIT for a digital research environment. The goal is to determine whether participants show greater physiological arousal—measured through skin conductance, heart rate, and respiration—when exposed to crime-related “critical” stimuli compared …

Renewal Of The Mind: Forgiveness Through The Lens Of Christian Faith And Neuroscience, Khelen Walsh

University Honors Theses

Within Christian theology, forgiveness is a foundational concept that is often understood as a divine command, a spiritual practice, and a path toward reconciliation and personal growth. Recent neuroscientific research further supports this viewpoint, providing data that shows forgiveness engages neural systems responsible for emotional regulation, empathy, moral reasoning, and perspective-taking. Through neuroplasticity, repeated acts of forgiveness reshape the brain, strengthen connections between prefrontal and limbic regions, reduce amygdala reactivity, and enhance emotional stability and cognitive flexibility. Although forgiveness offers many benefits, modern culture frequently distorts its meaning, framing it as a sign of weakness, gullibility, or a form of …

Capacity, Allocation And Update Dynamics Of Human Memory Systems, Shaoying Wang

Electronic Theses and Dissertations

Information is encoded and stored in three types of memory: sensory memory (SM), short-term memory (STM), and long-term memory (LTM). SM has a large capacity but retains information for only a brief period. When information transfers to STM, only a limited amount can be stored. Information in STM can then be transferred to LTM, which has a much larger capacity and longer retention time. STM is often conceptualized as working memory (WM) to highlight its role in active information processing. Due to the limited capacity of STM, it is commonly believed that STM serves as the bottleneck for information processing. …

Measuring Human Ability To Detect Emotional Energies In Transpersonal Fields Of Consciousness, Carol Richardson Phd, Mdiv, Mph

Journal of Conscious Evolution

This research presents original data from an online research survey with 111 respondents regarding their ability to detect emotional energies in transpersonal fields of consciousness in crowds and dyads. The data show that a majority of respondents, from 90% to 96.4%, reported experiencing different emotions “in the air,” such as excitement, tension, anxiety, anger, and love. Personal data responses include age, gender or gender identity, and worldview. Examples of possible worldviews include: “scientific, not religious, not spiritual”; “spiritual and scientific”; “religious”; and “religious and scientific.” Respondents were given two free-answer essay options: one in which they could describe their personal …

Trailblazing Pathways: Personal Traits Fueling Success For Underrepresented Minority Entrepreneurs, Rebecca P. Wilson

Dissertations

This study examines how entrepreneurial personality traits influence business outcomes among underrepresented minority entrepreneurs in the United States. Specifically, it investigates the effects of entrepreneurial self-efficacy, locus of control, risk tolerance, and extraversion on entrepreneurial performance, as well as the moderating role of grit and the mediating role of business networking. Although underrepresented minority entrepreneurs contribute significantly to innovation and economic growth, they continue to face persistent barriers, including limited access to capital, mentorship, and supportive entrepreneurial ecosystems. Guided by Trait Theory of Entrepreneurship and Social Cognitive Theory, this study employed a quantitative, cross-sectional survey design with embedded open-ended questions …

Unraveling The Lullabies Of Learning: Exploring The Role Of Individual Components Of Infant-Directed Speech In Language Learning, Stephanie L. Lopez

LSU Doctoral Dissertations

Children learn language more effectively from infant-directed speech (IDS) than adult-directed speech (ADS). Three experiments were run (a pilot and two full experiments) testing the effects of pitch and pitch variability on segmenting a target word out of the speech stream and then associating it to an object. Visual prosody via eyebrow movements and lip contours were added as additional cues after the Pilot Study. Additional factors included after the Pilot Study were shortened sentences from 10 syllables each to seven syllables each, shortened target words from three syllables to two syllables, consistent syllable onset of target words, and two …

“Home.”: A Trauma-Informed Children’S Book Exploring Secure Attachment For Children In Foster Care, Keeli Langford

Undergraduate Theses

Estimates suggest 6% of U.S. children (nearly half a million) will be placed in foster care at any point between their birth and eighteenth birthday (Turney & Wildeman, 2017). This population of children is subject to multiple adverse childhood experiences (ACEs; Turney & Wildeman, 2017). Such ACEs include parental divorce, parental incarceration, parental abuse, a household member with a psychological disorder, violence exposure, or a household member grappling with substance use. Exposure to childhood ACEs can negatively affect children behaviorally, emotionally, socially, and academically (Lawrence et al., 2006; McGuire et al., 2021). Research indicates youth in foster care are more …

The Influence Of False Memories On Eyewitness Testimony, Shay Kossen

Honors College Theses

This paper examines the role that false memories play in eyewitness testimony. Though eyewitness testimonies are a direct source of evidence regarding a crime, they are often flawed due to the malleable and reconstructive nature of memory, leading to many wrongful convictions. This review synthesizes previous research on false memories and eyewitness testimony to analyze the factors that contribute to inaccuracies in eyewitness testimony. This paper examines the origination of false memories, highlighting key factors such as the misinformation effect, source misattribution, and retention intervals. Additionally, this review analyzes factors from previous research that increase susceptibility to false memories, the …

Three Good Things And Family Process, Julia Prouty

Journal of Undergraduate Research at Minnesota State University, Mankato

There is a need for adaptive and affordable prevention/intervention strategies to promote happiness, health, and well-being in families. Three Good Things (3GT) is a free exercise from the field of positive psychology meant to shift an individual’s focus and perceptions towards gratitude. 3GT promotes focusing on gratitude by reflecting on what an individual is grateful for from the past day/week. Persons are encouraged to write down and share their 3GT with another individual. A mindset of gratitude is closely associated with improved happiness, health, and well-being. The exercise of reflecting on 3GT is adaptive to most individuals/families. To date, most …

The Role Of Temporal Predictability In Sustained Attention, Miho Kato, Harun Yörük, Thomas S. Redick

Annual Student Research Poster Session

Attention requires sustaining focus on information and goals over time. Sustained attention performance is affected by time and temporal predictability. Specifically, previous research showed that performance in sustained attention tasks decreases when the focus of attention is required to be sustained over a longer period of time, and performance increases when the duration to sustain attention is predictable (known as temporal predictability). The current research examines the relationship between the duration of sustained attention and temporal predictability with two cognitive tasks. In the Sustained Attention to Cue Task (SACT), participants were required to sustain their focus of attention on a …

Eeg And Media Multitasking: Adhd As A Moderating Factor, Xiaoying Guo

Theses and Dissertations

Media use has become an integral part of everyday life. It has risen dramatically over the past century with the advent of television, computers, and digital platforms, and more recently, it has been characterized by individuals using multiple devices simultaneously (Bushman & Anderson, 2001; Nielsen Media Research, 1998; Rideout & Robb, 2019, 2021). Media multitasking (MMT) has been linked to cognitive control challenges and attentional difficulties. This study examined EEG workload (Fz theta/Pz alpha ratio), survey accuracy, and ADHD traits (ASRS v1.1) in 33 adult participants across baseline and single-versus dual-media conditions. Results indicated that mental workload was significantly higher …

Is It Enough? Investigating The Effectiveness Of Adhd Accommodations For College Students, Sreekavya Mekala

Senior Theses

This study explores the effectiveness of accommodations given by the University of South Carolina (USC) for students diagnosed with attention-deficit/hyperactivity disorder (ADHD). A total of 435 students completed a survey divided into three groups: those diagnosed with ADHD (n = 74), those not diagnosed but familiar with someone with ADHD (n = 321), and those not diagnosed and unfamiliar with ADHD (n = 40). Results showed that while most students with ADHD were aware of accommodations, far fewer used them, and many reported inconsistent faculty understanding and hesitation due to stigma. Students familiar with ADHD viewed accommodations as generally fair …

From P-Values To Practical Relevance: An Introduction To Effect Sizes Through A Legal Psychological Example, Paul Riesthuis, Henry Otgaar, Tery Setiawan, Nathanael Sumampouw, Charlotte Bücken

Psychological Research on Urban Society

Null-hypothesis significance testing and p-values are frequently criticized for their focus on detecting non-zero differences and their inability to provide evidence for the null hypothesis. In this article, we highlight how effect sizes, when meaningfully interpreted, can address these issues. Specifically, we argue that researchers should consider the smallest effect size of interest (SESOI) - the smallest effect size that yields practical or theoretical relevance. We propose several methods for estimating the SESOI and present a consensus study among Indonesian professionals which can be used to estimate the SESOI for child eyewitness testimony research. Results suggest that most Indonesian professionals …

Investigating The Effects Of Cognitive Loads On Serial Dependence And Metacognition In Visual Working Memory, Wing Sum Chiu

Lingnan Theses (MPhil & PhD)

Humans tend to perceive the physical world based on the input from the recent past, a phenomenon known as serial dependence. Serial dependence typically results in an attractive bias toward prior stimuli to maintain perceptual stability. Nevertheless, it remains unclear whether cognitive loads can modulate serial dependence and metacognitive processes may depend on serial dependence. In this study, we investigate how memory and perceptual loads affect serial dependence, memory precision, and metacognition in visual working memory.

In Experiment 1, we manipulated memory load by varying set sizes. During each trial, 1, 3 or 6 Gabor patches (as a between-subjects factor) …

Leveraging Ai To Democratize The Hidden Curriculum In Medical Education: An Implementation Framework, James Keith Martin Ii, Mercedes Byrd

Libraries Scholarship

The “hidden curriculum” in medical education—comprising unwritten rules, values, and expectations—significantly impacts student success, yet remains inaccessible to students from underrepresented backgrounds. This paper presents a theoretical framework and practical implementation strategy for using artificial intelligence (AI) to democratize access to this hidden curriculum. We analyze how cognitive load theory and the Fast/Slow Thinking paradigm explain inequities in professional integration, then propose a comprehensive implementation approach to guide equitable AI integration. This model demonstrates how AI tools, when thoughtfully implemented, can reduce cognitive burdens on disadvantaged students, accelerate professional acculturation, and contribute to building an inclusive medical workforce.

Dynamical Regulation Of Blood Pressure And Cognitive Function, Joshua Sweigert, Tara Gruenewald, Margie Lachman, Teresa Seeman, Maxine Weinstein, Tse-Hwei Choo, Martina Pavlicova, Ramakrishna Mukkamala, Richard P. Sloan

Psychology Faculty Articles and Research

BACKGROUND

Blood pressure (BP) is not steady. It varies over intervals from months to consecutive cardiac cycles, and this variation contains meaningful information beyond mean BP. Variability over multiple clinic visits (VVV-BP) and during 24-h ambulatory monitoring (ABPV) is positively related to risk of stroke and coronary artery disease and negatively associated with cognitive performance. Beat-to-beat BP variation, often quantified as low frequency variability (0.04–0.15 Hz, LF-BPV), is less well-studied. Here, we examine the relationship between LF-BPV and cognitive outcomes in 1953 participants from the Midlife in the US study.

METHODS

Participants completed the Brief Test of Adult Cognition by …

Does Memory Trust Predict Confidence In Memory Performance?, Rachel Thayer, Jenna Thomason

2024 Symposium

Generally, people tend to believe that they are poor at remembering vital information while simultaneously displaying a tendency to overestimate their performance on memory tests. People display the usage of their metamemory, the control and awareness of memory, by monitoring and reporting how much information they have accurately remembered. Predicting the outcome of test scores is one way of testing metamemory, but this does not address how a person’s trust in their memory relates to their perceptions of how they performed on a test. The Squire Subjective Memory Questionnaire (SSMQ) measures beliefs about susceptibility to omission errors (excluding information), and …

Using Machine Learning Methods To Evaluate Undergraduates’ Executive Function In The Context Of Game-Based Measurement, Ming Chen

Dissertations, Theses, and Capstone Projects

Traditional performance-based measurements have faced criticism due to their potential to induce test fatigue and their limited ecological validity. In contrast, game-based assessments have demonstrated the capacity to engage participants effectively in tests and enhance ecological validity by replicating real-world scenarios. Nevertheless, conventional statistical approaches may prove insufficient in capturing the intricate, non-linear associations between participants' gaming performance and their cognitive capabilities. Leveraging the potential of machine learning (ML) techniques, which can model complex problems, offers a promising avenue for estimating students' performance in video games. This dissertation aims to explore various ML methods for the validation of three game-based …

The Interaction Of Multilingualism And Depressed Mood On Cognitive Set-Shifting, Annalise Caviasco

Dissertations, Theses, and Capstone Projects

Although findings are mixed, many researchers believe there are cognitive benefits to multilingualism, a phenomenon dubbed the “bilingual advantage”. Of these apparent benefits, cognitive flexibility, or the ability to shift thinking styles based on the context or specific demands of a certain situation, is thought to be highly relevant. Current literature suggests that one aspect of multilingualism, the practice of “code-switching” between languages throughout their daily lives, is related to increased general cognitive flexibility compared to monolinguals. Another branch of research on cognitive flexibility investigating the role of affect in cognition demonstrates that clinical depression as well as transient negative …

Unveiling The Precision Of Physiological Signals In Prediction Error During Fear Learning: Insights From Associative Strength And Generalized Uncertainty, Haja H. Jallo-Jamboria

Dissertations, Theses, and Capstone Projects

Prediction error (PE) is the discrepancy between expected and actual outcomes. It is a central mechanism in associative learning particularly within fear-conditioning paradigms. Identifying physiological markers of PE in aversive contexts has important implications for refining learning models and enhancing clinical interventions for anxiety-related disorders. This study examined skin conductance response (SCR) as a potential physiological index of PE by analyzing both anticipatory and omission-related responses across multiple learning phases. Participants completed a Pavlovian fear-conditioning paradigm in which two conditioned stimuli (CS+) signaled threat at different reinforcement probabilities: CS+100 (certain threat) and CS+50 (uncertain threat), alongside a non-reinforced safety cue …

Wavelength And Luminance Interaction On Spatio-Temporal Contrast Sensitivity Function, Taylan S. Ergun

Dissertations, Theses, and Capstone Projects

Contrast sensitivity (CS) measures the ability to discriminate objects from their backgrounds under varying conditions(Campbell & Robson, 1968). Contrast sensitivity is important for navigating the real world and operating under different light conditions. The contrast sensitivity function (CSF) reflects how the visual system performs under different conditions. This measure is crucial in assessing the health of the visual system (Chen & Gardner, 2021). CSF contributes to a deeper understanding of how the visual system processes and integrates properties of light to create visual sensation and perception. Human contrast sensitivity depends on the viewing conditions such as field size, luminance, color, …

From Coping Strategies To Fan Well-Being: Resource Dynamics Of Team Identification, Impulse Control, And Psychological Capital In Negative Experiences, Hyun-Woo Lee, Yelim Yoo, Kun Chang, Jun-Phil Uhm

Journal of Applied Sport Management

Guided by conservation of resources theory, the authors examine how team identification, impulse control difficulties, coping strategies, and psychological capital shape fans’ well-being in negative fan experiences. Survey from 300 sport fans were analyzed using structural equation modeling. Results showed that identification promoted adaptive coping and reduced cutting off reflected failure, whereas impulse control difficulties increased denial and cutting off reflected failure. Denial unexpectedly enhanced psychological capital while reducing well-being, and venting functioned as a double-edged mediator across positive/negative pathways. Psychological capital was the strongest predictor of well-being, underscoring its role as a central resource linking coping to outcomes.

Collaborative Memory And Metamemory: The Impact Of Normative And Informational Motivations On Conformity, Karen Rodriguez

Dissertations, Theses, and Capstone Projects

Collaborative memory studies have typically explored the cognitive mechanisms that underlie differences between collaborative and individual memory performance. Despite the social nature of collaboration, few studies have examined the impact of social motivations on collaborative memory. When retrieving information with groups, people may not only be motivated by a desire to be accurate (i.e., informational motivations), but may also be guided by social norms (i.e., normative motivations), such as prioritizing agreeability or alignment with group members (Cialdini & Goldstein, 2004). Similarly, retrieving information with others may also prompt individuals to reflect more on their own memory processes. However, few studies …

Characterization Of The Attentional Profile In Women And Girls With A Fragile X Premutation Allele, Shira Russell-Giller

Dissertations, Theses, and Capstone Projects

The fragile X premutation (PM), characterized by 55 to 200 CGG repeats in the FMR1 gene, is associated with diverse clinical outcomes, including cognitive and neuropsychiatric changes. Despite most individuals with a PM presenting without overt clinical symptoms, adults face increased risks for conditions associated with a PM, including higher rates of attention and executive difficulties. This dissertation investigates the developmental trajectory of attention and executive functioning changes in females with a PM using a series of prospective studies employing the Attention Network Test (ANT). Study 1 re-analyzed prior data on sustained attention in women with a PM, revealing significant …

Associations Between Parental Audism/Linguisticism And Deaf Individuals' Well-Being: Mediation By Interpersonal Needs And Relationship Quality, Dilan H. Arreguin, Crystal D. Oberle

JADARA

This study investigated whether audism and linguisticism from the parents of physically deaf or culturally Deaf individuals—that is, parents’ expectation of their child to communicate within audio-normative standards rather than use sign language—is related to poor mental health of the child. It also investigated whether these relationships are accounted for by interpersonal needs or child-parent relationship quality. For this study, 104 D/deaf adults completed a survey with measures of parental audism and linguisticism, depression, anxiety, thwarted belongingness, perceived burdensomeness, parental closeness, and parental conflict. Parental audism and linguisticism positively correlated with depression and anxiety, and these relationships were mediated by …

Conscious Control: A Case Study On Self-Monitoring And Interventions In Maladaptive Daydreaming, Caleb Chan

McNair Research Journal SJSU

Maladaptive daydreaming (MD) is a persistent mental activity

characterized by immersive, excessive daydreaming that disrupts daily

life. This study examines the effectiveness of self-regulation strategies

in managing MD, including cognitive techniques, behavioral

adjustments, technology-assisted cues, and environmental

modifications. Using a single-subject ABA design, each intervention

phase lasted one week, with MD episodes tracked through self-reported

diaries and EEG monitoring. The results demonstrated that cognitive

reframing and task switching produced the most sustained reductions in

MD episodes, while technology-assisted cues had diminishing

effectiveness over time due to adaptation. Environmental modifications,

particularly workspace reorganization, con- tributed to long-term

improvements, while lighting adjustments …

Proposed Theoretical Model Of Pediatric Onset Multiple Sclerosis And Restrictive Eating Behaviors, Anna L. Smith

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Multiple Sclerosis (MS), a chronic, demyelinating, autoimmune disease that causes an array of physical and cognitive symptomatology, is commonly diagnosed in adulthood. Pediatric Onset Multiple Sclerosis (POMS) is characterized by diagnosis of the disease before age 18 and accounts for about 5% of MS cases. While there is a growing body of literature examining the impact of adult-onset multiple sclerosis on psychosocial functioning, research specifically addressing POMS remains limited. Moreover, there is a notable gap in the literature regarding the risk of eating disorders among individuals with POMS. This paper will explore a constellation of potential risk factors that may …

Understanding The Gaming Disorder–Depression Co-Occurrence: A Narrative Literature Review, An-Pyng Sun, Stephanie Diez

Social Work Faculty Research

Because gaming disorder (GD) often co-occurs with depression, understanding how both disorders work together enables clinicians to better treat individuals with GD–depression comorbidity. The extant literature on GD–depression comorbidity is unsystematic and contradictory, with some studies suggesting depression predicts GD but not vice versa, some claiming GD predicts depression but not vice versa, and some proposing a bidirectional relationship between the two. The goal of this narrative review is to explore and organize these findings to establish a holistic and coherent conceptual framework that explains how GD co-occurs with depression.
