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 …

Separating Memory And Attention In Secondary Tasks, Anne Olsen

USF Tampa Graduate Theses and Dissertations

Memory and attention are intricately intertwined throughout life. How these processes interact and effect the encoding process shows to be just as complex and intricate. A recent study by Sahakyan and Malmberg (2018) revealed that when cognitive resources are strained during encoding, long-established retrieval patterns in both recall and recognition alter. These patterns found were suggested to be the result of an altered mechanism in strengthening processes that eliminated trace strengthening when cognitive resources were strained. This work investigates those claims through a direct replication of the original experiment (Experiment 1) as well as investigating the components of the secondary …

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 …

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 …

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 …

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 …

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 …

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.
