Cbd's Impact On Learning, Memory, And Anxiety: A Dose Response, Audrey Camacho

Psychology ETDs

Cannabidiol (CBD) is widely utilized for its therapeutic properties, yet its impact on an unmanipulated model at baseline behavior remains poorly understood. This study investigates CBD’s dose-dependent behavioral profile on spatial learning, memory, and anxiety using Long-Evans rats. Subjects received a vehicle, 20 mg/kg, or 40 mg/kg CBD dose prior to assessment in the Morris Water Task (MWT) and Elevated Plus Maze (EPM). MWT results indicated consistent Day 1 learning, but the 40 mg/kg dose induced a temporary disruption 24 hours post-treatment. Performance returned to baseline by day 6. On the EPM, traditional anxiety markers remained unchanged. While CBD did …

Assessment And Classification Of Idiosyncratic Behavioral Sequences In Rodent Navigation, Max G. Segal

Psychology ETDs

The Morris Water Task (MWT) has been the gold standard assessment of place learning and memory for over four decades, yet the processes that contribute to successful navigation are not completely understood. It is generally posited that rats learn to navigate directly to a place; however, navigation is not perfectly direct but contains variation in swim speed and trajectory resulting in efficient, yet suboptimal paths. Gonçalves-Garcia et al. (2024) demonstrated that path topography is quantitatively similar across trials within individual rats for a given start location, and dissimilar between rats and different start locations within rat. This suggests rats may …

How Does Age Affect Our Memory? Semantic Relatedness In Proper Name Recall, Art Beqiraj

Masters Theses, 2020-current

Proper names belong to a distinct class of lexical items that pose challenges for encoding and retrieval across people of all ages. Unlike common nouns, and the exception of nicknames, proper names are arbitrary relative to their referent. Forgetting someone’s name is not only seen as a social faux pas but may be particularly concerning for older adults due to its interpretation as a cognitive decline indicator. Prior research has shown that when names are physically descriptive of their referent (e.g., a giraffe called ‘Lengthy’), they are better learned and recalled; however, the extent to which descriptiveness without a visual …

Factors Relating To Memory, Kyra Vanheirseele

Honors Theses

Cognitive and emotional processes are increasingly recognized as important factors influencing memory functioning. In the current study, the associations between depressive symptoms, selfcritical rumination, sleep quality, and cognitive confidence with self-referent memory recall were examined in a sample of undergraduate students (N = 60; 70.0% female, 21.7% male; M age = 19.36 years, SD = 1.21). The sample was predominantly White (73.2%), with additional representation from Black or African American (14.3%), American Indian or Alaska Native (1.8%), Asian (1.8%), and other racial groups (8.9%). Using established self-report measures, participants reported on depressive symptoms (Schmitt & Maes, 2000; Sauer et al., …

Storytelling As A Pedagogical Tool For Improving Memory In Lectures, Sydney E. Rutter

Honors Theses

The purpose of the study was to examine if utilizing storytelling in lectures caused a positive effect on students' memory over a week-long period. Storytelling has been used as a mnemonic device to improve memory, however its benefits have not been experimented much in higher education. In this study, 53 undergraduate psychology students were placed into two groups: traditional lecture or storytelling lecture. Students then watched the lecture they were assigned, both lectures discussed the ASURE model. A week later, students returned and took a 17 question memory test. Results indicated that students who watched the storytelling lecture performed significantly …

How Schema Knowledge Affects Memory, Sarah Waller

Psychological Science Undergraduate Honors Theses

Schemas are a type of semantic knowledge that are formed from generalizations about the world. Schemas are essentially expectations about how we expect the world to be, and they are helpful for understanding and categorizing information we encounter. Prediction errors, which occur when our predictions are violated, are caused by events that are inconsistent with our schemas. Current findings on prediction error’s effects on memory are contradictory, with some studies stating that the presence of a prediction error enhances memory for a context, while other research disagrees. A popular theory proposes that prediction error causes a boost in memory for …

Negation And The Backfire Effect, Caden Fowler

Psychological Science Undergraduate Honors Theses

Quick! Do not think of a polar bear. Did you think of a white bear? As Russian author Fyodor Dostoevsky wrote in his 1863 essay “Winter Notes on Summer Impressions,” “[when tasked to not think of a polar bear] you will see that the cursed thing will come to mind every minute.” The consequence of negation without context (i.e., unlicensed negation; Levine & Hagaman, 2008) is what has come to be referred to as the “backfire effect,” a phenomenon where correcting misinformation strengthens belief in that information rather diminishing it (Ecker, et al., 2020). Fake news and misinformation in …

Visual Aids And Numeracy In Healthcare: Leveraging The Drawing Effect, Zephyr J. Markley

Capstone Showcase

Healthcare decisions often require patients to interpret numerical risk information under stress, yet many struggle with low numeracy, which can distort comprehension and undermine informed consent. Well-designed visual aids can improve diagnostic inference, calibrate confidence, and support better choices, especially for patients with limited numeracy, but their impact depends on whether users can actually interpret the format accurately. Drawing may further enhance these tools by adding a tactile, generative layer that engages visual, semantic, and motoric processing while helping patients organize information into concrete models.

Passive visual aids appear useful but limited because they often position patients as observers rather …

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 …

Echoes Of Longing, Mahalexmi Mohan

Masters Theses

Loss lingers like a shadow, a weight no time can lift. Longing becomes a silent scream, echoing within, unanswered. Internal pain festers in the quiet, where unhealed wounds weave themselves into the fabric of being. Each breath is both survival and surrender, a fragile balance between hope and the hollow ache of what was, what will never be, yet could be.

Abstract

My work is deeply influenced by my experiences within a dysfunctional family structure and is explored through the relationship of emotional vulnerability and its effect on self-worth. Layered into the work is a confrontation with the scars, conflict …

Looking Forward To It: Investigating The Role Of Anhedonia In Episodic Future Thinking, Sarah Corner, Alicia E. Meuret

Psychology Theses and Dissertations

Episodic future thinking, or our ability to simulate personal future events, is implicated in a range of important functioning from problem solving to emotion regulation. However, individuals with clinical diagnoses like depression and schizophrenia struggle to produce future thinking that is vivid and detailed. While these deficits mirror well-document autobiographical memory deficits, they remain poorly understood. The current study aimed to examine the role of anhedonia in episodic future thinking vividness using a within-subjects dimensional approach. A mixed sample of sixty-five undergraduate students and community adults completed two future thinking tasks and one autobiographical memory across two study visits, during …

Storytelling: A Natural Mnemonic, Hailey Stephens

Honors Theses

The present study explored the effectiveness of storytelling as a teaching method in enhancing memory performance for educational material compared to traditional lecture-based instruction. Memory plays a crucial role in learning, and effective teaching strategies should facilitate information encoding, retention, and retrieval. Storytelling, an ancient yet often overlooked pedagogical tool, has been shown to engage students emotionally and cognitively, making presented content more memorable. In the present study, participants were randomly assigned to either a storytelling-based instruction group or a traditional lecture group. Both groups received instruction on the ASSURE Model and were tested immediately after the lesson and again …

Penny For Your Thoughts: Exploring Mechanisms Linking Socioeconomic Status And Cognition, Colton Hunter

Graduate Theses and Dissertations

Socioeconomic status is a complex psychological construct linked to a number of professional and personal barriers, including cognitive deficits. Throughout this dissertation, I seek to examine the mechanisms that link socioeconomic status and cognition. First, I explore potential mediators in the link between adolescent family income and cognition in adulthood, identifying education, stressful life events, inflammation, and family education expectations as significant mediators. Next, I examine the effects of writing-based stress manipulations on long-term memory and working memory, as these effects may mimic stress from financial worry. In doing so, I identify potential effects on working memory parameters. Finally, in …

Differences In Performance In Mental Rotation And Short-Term Free Recall In Gender Minorities, Katheryne Renee Wood

Electronic Theses and Dissertations

The study examined mental rotation, short-term free recall, state anxiety, and gender expression through masculinity and femininity. This study addressed gaps in literature examining gender differences in gender minority groups by investigating gender differences in two tasks: mental rotation and short-term recall. Participants are categorized into four gender groups: cisgender men, cisgender women, non-binary, and binary transgender. In accordance with previous literature, it was hypothesized that men would outperform women in mental rotation, women would outperform men in short-term free recall performance, and that non-binary individuals would operate separately from other groups. Anxiety was recorded as a possible covariate, but …

Quantity Over Quality? What Pupil Dilations Tell Us About Cognitive Effort At Learning., Durna Alakbarova

Psychology Dissertations - Archive

The current study examined whether pupil dilations at encoding reflect cognitive effort participants engage in a task. According to the cognitive effort hypothesis of pupil dilations, increases in cognitive effort cause activation of the locus coeruleus–norepinephrine (LC-NE) system, which is reflected in larger pupil dilations. While task-evoked pupillary responses (TEPRs) have been used as a marker of cognitive effort, it remains unclear whether changes in pupil size reflect encoding success. We proposed that the reason for conflicting findings on the topic is a lack of nuance in examining cognitive effort. Specifically, we suggested that cognitive effort consists of two separate …

How To Remember Names Lesson Plan, Madison Paige Davis

ENGS 15.11: Design and Education

This is an introductory lesson intended for any high school- or college-aged student who wants to learn how to deepen connections with others, whether for personal or professional relationships. Through a combination of lecturettes, discussions, reflection time, and activities/ quizzes, students will learn and apply their knowledge about the benefits, science, history, and strategies of remembering people’s names so that they are able to use names in future conversations. The final activity will be a simulation of real life scenarios where students will have to either remember and use a stranger’s name or practice asking for their name, whether they …

Assessing Comprehension And Competence In Bottlenose Dolphins (Tursiops Truncatus) On The Concept: Do Something Different, Charlotte M. Mulligan

Theses and Dissertations

Many studies have been conducted using a training paradigm based on the research of Pryor et al. (1969) wherein the participants are trained on the abstract concept: do something different. This paradigm challenges working memory and requires the participants to respond with a behavior, either previously trained or novel, which has not yet been offered within the session. The work of Braslau-Schneck (1994) expanded this concept and demonstrated the ability of dolphins to successfully complete this task in synchronized pairs, though the method of accomplishing this task remained unclear. The present research was conducted as part of a broader …

Strategies For Misinformation Correction: Evidence For The Power Of Negation, Angel Houts

Graduate Theses and Dissertations

The current study investigated the effectiveness of different correction strategies for misinformation using a 2 (Source: no source, credible source) x 2 (Structure: negation, affirmation) within-subjects design with an additional control condition that had no corrections. Participants read 40 Twitter-like statements, which included 25 pieces of misinformation and 15 truthful statements, and rated their emotional responses on a Likert scale. After completing a distractor task, participants read additional Twitter-like statements across five different conditions. The first four conditions aimed to correct misinformation: negation with a credible source, negation without source, affirmation with a credible source, affirmation without source. The fifth …

Developing A Fair And Interpretable Representation Of The Clock Drawing Test For Mitigating Low Education And Racial Bias., Jiaqing Zhang, Sabyasachi Bandyopadhyay, Faith Kimmet, Jack Wittmayer, Kia Khezeli, David J. Libon, Catherine C Price, Parisa Rashidi

Rowan-Virtua School of Osteopathic Medicine Departmental Research

The clock drawing test (CDT) is a neuropsychological assessment tool to screen an individual's cognitive ability. In this study, we developed a Fair and Interpretable Representation of Clock drawing test (FaIRClocks) to evaluate and mitigate classification bias against people with less than 8 years of education, while screening their cognitive function using an array of neuropsychological measures. In this study, we represented clock drawings by a priorly published 10-dimensional deep learning feature set trained on publicly available data from the National Health and Aging Trends Study (NHATS). These embeddings were further fine-tuned with clocks from a preoperative cognitive screening program …

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 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 …

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 …

Relating Perception And Memory For A Novel Set Of Reconfigurable Auditory Stimuli, Nathan Francis Gillespie

Legacy Theses & Dissertations (2009 - 2024)

Although real-life events are complex and temporally extended, most memory research employs discrete, static stimuli presented in the visual modality. We begin to bridge this gap using a novel set of auditory stimuli constructed by adjusting the distribution of power across upper frequency bands. Across three experiments, participants rated similarity between pairs of sounds and engaged in a recognition memory task. We applied non-metric multidimensional scaling to similarity ratings to obtain a three-dimensional psychological representation of the stimuli. The representation inferred from the similarity ratings predicted recognition memory performance for single probe sounds following sequential presentation of two sounds. Recognition …

The Effect Of Study Music Tempo On Short Term Memory Retention In Reading And Verbal Comprehension, Payton Ballinger

Seaver College Research And Scholarly Achievement Symposium

This study experimentally investigated the effect of background music on retention as it relates to short term memory. Eighty undergraduate participants from various fields of study at Pepperdine University were randomly assigned to either listen to or read a preselected passage while listening to preselected excerpts of fast or slow tempo music. All participants were then asked to complete a 10 question test covering the material presented. There was a main effect specifically for music tempo in that participants who were exposed to background music at a slower speed while either reading or listening to a passage scored higher on …

Neuroplasticity In The Dentate Gyrus: A Multimethod Investigation On Hippocampal Ltp Following Prenatal Alcohol Exposure, Monica Goncalves-Garcia

Psychology ETDs

Studies have demonstrated alcohol-related deficits in LTP associated with histaminergic and glutamatergic impairments. The histaminergic H3R inverse agonist ABT-239 has shown promise in reversing these deficits. The present study focuses on another H3R inverse agonist, SAR-152594, and its impact on LTP deficits following moderate PAE. The findings reveal that systemic administration of 1 mg/kg of SAR-152594 reverses deficits in potentiation fEPSPs in adult male rats exposed to moderate PAE. Time-frequency analyses of evoked responses indicate PAE-related reductions in power during the fEPSP and increased power during later components of evoked responses, both reversed by SAR-152594. These results provide further evidence …

Multiple Timescales Of Temporal Context In Risky Choice: Behavioral Identification And Relationships To Physiological Arousal, Hayley R. Brooks, Peter Sokol-Hessner

Psychology: Faculty Scholarship

Context-dependence is fundamental to risky monetary decision-making. A growing body of evidence suggests that temporal context, or recent events, alters risk-taking at a minimum of three timescales: immediate (e.g. trial-by-trial), neighborhood (e.g. a group of consecutive trials), and global (e.g. task-level). To examine context effects, we created a novel monetary choice set with intentional temporal structure in which option values shifted between multiple levels of value magnitude ("contexts") several times over the course of the task. This structure allowed us to examine whether effects of each timescale were simultaneously present in risky choice behavior and the potential mechanistic role of …

An Examination Of Working Memory In Dancers And Non-Dancers, Mason Low

All Master's Theses

The present study examined the behavioral working memory differences between dancers and non-dancers. Previous research has indicated that dance can provide an enhancing effect on working memory, particularly in non-dancers. A Dance History Questionnaire along with the letters backward, digits backward, digits forward, letters forward, and abstract visual subtests of the Test of Learning and Memory II was used to collect data. The current study found that dancers had greater visuospatial memory than non-dancers and that dance experience may have an effect on certain working memory tests such as the letters forward subtest.

Recall Me Maybe: The Effects Of Music-Evoked Mood On Recognition Memory, Caroline Grace Coey, Youstina Tadros, Sinead Doogan, Melody Alvarez

Science University Research Symposium (SURS)

The current study aims to further explore the relationship between musically evoked emotional states and recognition capabilities. Previous research has demonstrated emotional congruency between musical stimuli and subsequent task performance (Mitterschiffthaler et al., 2007). The background music’s emotional valence provides additional insight into how to guide the perception of events and how music-evoked emotions can impact memory (Scherer & Zentner, 2001; Hanser et al., 2015). For instance, happy people will have an easier time remembering positive experiences, rather than sad, or negatively valanced ones while those who are sad will better remember negative experiences, rather than happy, or positively valanced …

The Effects Of Acute Exercise Intensity On Memory: State-Dependent Learning, Lauren E. Fuglaar, Rylie S. Mangold, Sierra N. Petty

Honors Theses

The Encoding-Specificity Paradigm states that memory recall will be enhanced when contextual factors are congruent between memory encoding and memory retrieval (i.e., state-dependent learning). However, minimal research has evaluated this paradigm in the exercise domain. The purpose of this study was to evaluate the effects of acute exercise intensity on memory while considering these potential state-dependent effects. Forty-eight university students completed a within-subject experiment involving seven laboratory visits, during which they encoded a list of 15 words and were subsequently asked to free-recall as many of these words as possible. The encoding and retrieval phases were matched or mismatched by …

Mechanisms Of False Memories In Bilinguals, Bianca Valentina Gurrola

Open Access Theses & Dissertations

Research on false memory in bilinguals has discovered that false memories can transfer across languages and occur at a higher rate than for within-language false memories (Marmolejo et al., 2009). However, the exact conditions that cause the stronger between-language false memory effect are not clear, nor is it clear how language proficiency influences the production of false memories. The present study had three goals. First, we tested whether the stronger between- language false memory effect relative to the within-language effect would replicate. Second, we examined whether bilinguals could integrate information across languages to form false memories by implementing a mixed-language …
