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 …

Reducing The Complexity Of The Experimental Design Attenuates Trait-Level Effects In Threat Safety Discrimination Learning, Justin M. Lazzarino

Dissertations, Theses, and Capstone Projects

Trait measures of negative emotionality have sometimes been shown to play a role in shaping threat learning, but findings are mixed. For example, Johnson et al (2023) showed that the inhibitory and prospective subscales of the Intolerance for Uncertainty Scale (IUS) were associated with diminished and enhanced threat-safety discrimination, respectively, during the acquisition phase of a Pavlovian fear conditioning task. This finding was subsequently replicated in an independent sample (Kinney-Petrucha, 2024, unpublished). However, these findings and other trait-level fear acquisition effects have not been consistently observed in the broader fear learning literature. Variation in the complexity of or uncertainty inherent …

What Learning Benefits Can Leadership Bring To Social Dilemma Situations?, Kyisha M. Walter

College of Arts & Sciences Senior Theses

Social dilemmas are ethical dilemmas that citizens, students and employees face every day. When faced with a social dilemma, an individual must work alone and along with others in a group. These situations create conflict between personal and group interests and can be easily mismanaged. Research has started to tackle the question of how we can teach people to best manage a social dilemma. The current exploratory study asks the same question with respect to leadership. Undergraduate students (N=20) played a social dilemma board game twice in groups of four, received a lesson on social dilemmas, and completed …

Towards An Understanding Of Learning In Immersive Virtual Reality: Investigating Learning Affordances To Bridge Theory And Practice, Gregory Mcgowin

Graduate Studies Theses and Dissertations 2026

This dissertation examines how modality-specific scaffolding shapes performance, presence, and transfer in immersive virtual reality (I-VR). Framed through theories of extended cognition, real-time guidance is conceptualized as cognitive scaffolding that structures perception and action by embedding task-relevant information within the environment. Situated within the learning sciences and informed by 4E cognition (embodied, embedded, enactive, extended), this work develops a framework for understanding how I-VR affordances relate to learning and performance.

The empirical study investigates how scaffolding modality (audio vs. visual) influences presence and performance in a VR racing simulation. Using a 3 × 2 × 2 mixed factorial design, 111 …

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 …

Examining Video-Based Learning In Higher Education, Kay (Catherine) L. Tislar

Dissertations, Master's Theses and Master's Reports

Instructional video has proliferated recently due to the explosion in popularity of TikTok and YouTube. However, most videos are not developed using principles derived from research and instructional design theories that have been tested with content presented in other types of media (de Konig et al., 2018). Many of these principles are based on the Cognitive Theory of Multimedia Learning, including research on the seductive detail effect; seductive details are “interesting but irrelevant details that are added to a passage to make it more interesting” and have been shown to harm learning (Harp & Mayer, 1997). This has motivated the …

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 …

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 …

Brainwaves, Memory, And Reward, Rebecca Mccune

Dissertations, Theses, and Capstone Projects

The development of effective educational curricula for enhancing learning involves the crucial consideration of effort and rewards. In the realm of education, teachers commonly employ rewards as motivational tools. Traditionally, these rewards are given to students as a recognition of their successful performance. However, a thought-provoking idea emerges: What if we were to extend rewards to students not solely based on accurate answers, but also on the effort they invest, even in cases where their actual response might be incorrect? Our study explores the potential impact of this approach on the way information is absorbed and subsequently retained, specifically focusing …

Moving Beyond Fulfillment: Wisdom Years Stories Of Passion, Perseverance, And Productivity, Kenneth A. Kiewra, Jessica Walsh, Chris Labenz

Department of Educational Psychology: Faculty Publications

Seven participants were interviewed to uncover how they remain so productive in their wisdom years, those typically marked by retirement. Participants included a leading educational psychologist, a renowned national television news anchor, a four-time national champion collegiate coach, the founder and former chief executive of Arbor Day Foundation, a university scholar turned playwright, and two female adventurers who quit their jobs, sold their possessions, and have lived a nomadic life, hiking thousands of miles throughout America. Their wisdom years stories describe how and why they shun retirement and remain productive. The article concludes with seven advice-laden conclusions for readers: (a) …

The Effect Of Testing On New Learning Of Related And Unrelated Text Sections, Katie Ingram

UNF Graduate Theses and Dissertations

When individuals are presented with a variety of materials, including word lists, face-name pairs, text passages, and more, the presence of a test between sections can enhance future section learning, a phenomenon called the forward testing effect (FTE). In addition to the FTE, studies have suggested that a decrease in the relatedness of the subject matter units can increase learning of the material. The current study examined the interaction between the presence of a test and the relatedness of material using text sections and cued-recall questions. Participants were 119 individuals assigned to a related test, related no-test, unrelated test, or …

Birds Of A Feather: Exploring Social Facilitation Effects On Learning And Suboptimal Choice In Pigeons (Columba Livia), Peyton Mueller

Theses and Dissertations--Psychology

The social facilitation effect describes a change in the behavior of an individual due to the presence of another organism of the same species (i.e., a conspecific). Many theories exist that attempt to explain why this change in behavior exists across species. A set of four experiments were executed to best explain how pigeons learn in the presence of non-competing conspecifics. The first experiment sought to replicate an interesting effect previously found in cockroaches and rats, such that conspecific presence inhibits performance early in training but facilitates it with increased training. The second experiment placed the novel response acquired in …

Testing An Overtraining Protocol For Fear Learning In Humans, Gordon M. Haskell

Dissertations, Theses, and Capstone Projects

Successful regulation of fear memories is a fundamental tenet to the exposure-based therapies often employed by mental health professionals for individuals with PTSD, phobias, and other anxiety disorders. Consequently, the efficacy of these treatment methodologies is largely dependent on the strength of the fear memory, as stronger memories are often characterized by an increased resistance to extinction and heightened fear recovery. However, there is little consensus within the scientific community regarding how to effectively maximize fear memory strength in human studies, and the literature exploring the impact of variability in acquisition parameters on memory strength is sparse. Here, we tested …

Individual Differences In Structure Learning, Philip Newlin

Theses and Dissertations

Humans have a tendency to impute structure spontaneously even in simple learning tasks, however the way they approach structure learning can vary drastically. The present study sought to determine why individuals learn structure differently. One hypothesized explanation for differences in structure learning is individual differences in cognitive control. Cognitive control allows individuals to maintain representations of a task and may interact with reinforcement learning systems. It was expected that individual differences in propensity to apply cognitive control, which shares component processes with hierarchical reinforcement learning, may explain how individuals learn structure differently in a simple structure learning task. Results showed …

The Interaction Of Spaced Retrieval Practice And Element Interactivity., Cameron K. Mattingly

College of Arts & Sciences Senior Theses

Our study investigates the interaction of retrieval practice and element interactivity. Spaced practice is the process of breaking up the retrieval of information into smaller chunks across a longer period of time as opposed to learning everything in one time block. Retrieval practice is the process of testing yourself on previously learned material. Spaced retrieval practice is the merger of these two ideas. This style of learning is well-suited for learning many items that must be retained indefinitely (Lyle et al., 2019). Element interactivity describes the amount of learned items (elements) that are interrelated and must be processed together in …

Classical Conditioning Of Cognitive States, Arthur Burns

Neuroscience Honors Papers

Classical conditioning has been a fundamental concept and practice throughout the history of psychology. While classical conditioning traditionally seeks to elicit target behaviors in correlation to specific stimuli, we sought to do the same with cognitive states in place of behaviors. Specifically, we wanted to determine the effectiveness of conditioning states of cognitive arousal in human participants in conjunction with cues presented in a designed learning task. We designed a cognitive task specifically for this research, referred to as “the Tone Pitching Task”, which utilized a combination of working memory and mental processing in order to elicit cognitive arousal and …

Parent Reports Of Executive Functions In Students With Learning Disability, Jane Roitsch, Annemarie L. Horn, Lisa Morin

Communication Disorders & Special Education Faculty Publications

This study examines the results of the Behavior Rating Inventory of Executive Function (BRIEF-2) (Gioia et al., 2015) reported by parents of children with Specific Learning Disability (LD) and/or other comorbid disabilities. LD is most notably associated with comorbid attention deficit hyperactivity disorder (ADHD) (Alloway & Stein, 2014; Westby &Watson, 2004; Willcutt et al., 2013). A total of 43 parents completed the BRIEF-2 rating scale. Findings suggest children with LD and ADHD display greater challenges with inhibition, working memory, planning, along with greater challenges in organization and metacognition. Parents of children with LD reported their children have greater levels of …

Intermittent Hypoxia And Effects On Early Learning/Memory: Exploring The Hippocampal Cellular Effects Of Pediatric Obstructive Sleep Apnea, Arvind Chandrakantan, Adam C Adler, Mehmet Tohsun, Farrah Kheradamand, Russell S Ray, Steven Roth

Faculty, Staff and Students Publications

This review provides an update on the neurocognitive phenotype of pediatric obstructive sleep apnea (OSA). Pediatric OSA is associated with neurocognitive deficits involving memory, learning, and executive functioning. Adenotonsillectomy (AT) is presently accepted as the first-line surgical treatment for pediatric OSA, but the executive function deficits do not resolve postsurgery, and the timeline for recovery remains unknown. This finding suggests that pediatric OSA potentially causes irreversible damage to multiple areas of the brain. The focus of this review is the hippocampus, 1 of the 2 major sites of postnatal neurogenesis, where new neurons are formed and integrated into existing circuitry …

Effect Of Environmental Enrichment On The Brain And On Learning And Cognition By Animals, Thomas R. Zentall

Psychology Faculty Publications

The humane treatment of animals suggests that they should be housed in an environment that is rich in stimulation and allows for varied activities. However, even if one’s main concern is an accurate assessment of their learning and cognitive abilities, housing them in an enriched environment can have an important effect on the assessment of those abilities. Research has found that the development of the brain of animals is significantly affected by the environment in which they live. Not surprisingly, their ability to learn both simple and complex tasks is affected by even modest time spent in an enriched environment. …

Examining The Relationship Between Confusion And Learning: A Descriptive Meta-Analysis, Dara L. Mcweeney, Aaron Y. Wong, Caitlin Mills

Honors Theses and Capstones

Previous research into confusion and learning neglects to investigate how this relationship varies when faced with impact factors such as multiple types of affect and learning measurements, learning environment, or grade level. Moreover, past research also reports di-verse effect size values for this relationship, making the correlation ambiguous. As such, the current research seeks to reconcile these nuances between confusion and learning through a meta-analytic approach. In this analysis, it was found that there was no relationship between confusion and learning gains, or in the subgroup analysis of grade level. Since only one impact factor, grade level, was analyzed, it …

Better With Science: Strengthening Patron Learning, Heather Simmons, Alyson Drake, Joseph Lawson

Presentations

A baseline understanding of cognitive theory and educational psychology concepts is critical to successful student learning. With librarians in all settings providing more teaching and training than ever, designing educational experiences with these concepts in mind will result in greater retention and understanding for their patrons. This program will discuss five important ideas from cognitive learning science and give examples of how librarians and other information professionals can incorporate those theories into their instructional offerings. Participants will then work in groups to brainstorm ways various theories can be applied as they design or restructure their own instructional programs.

Reconsolidation: Unique Cognitive Process Or State Dependent Learning?, Chris Kiley

UNLV Theses, Dissertations, Professional Papers, and Capstones

Accessing a previously consolidated memory trace brings it back into a labile state where it must then undergo a re-stabilization process known as reconsolidation. During this process memories are susceptible to interference and may be updated with new information. Reconsolidation has been demonstrated in animals as well as in the procedural and episodic human memory systems. However, it is still unclear when the effect will occur. Some studies suggest that reconsolidation is only necessary when new information is presented in the same spatial context or when prediction error occurs. More recent work has provided evidence that reconsolidation could be due …

Information Sampling, Judgment And The Environment: Application To The Effect Of Popularity On Evaluations, Gaël Le Mens, Jerker Denrell, Balázs Kovacs, Hülya Karaman

Research Collection Lee Kong Chian School Of Business

If people avoid alternatives they dislike, a negative evaluative bias emerges because errorsof under-evaluation are unlikely to be corrected. Prior work that analyzed this mechanismhas shown that when the social environment exposes people to avoided alternatives (i.e. itmakes them resample them), then evaluations can become systematically more positive. In this paper, we clarify the conditions under which this happens. By analyzing a simple learning model, we show that whether additional exposures induced by the social environment lead to more positive or more negative evaluations depends on how prior evaluations and the social environment interact in driving resampling. We apply these …

Does Testing Episodic "Lion-Tiger" And/Or "Tiger-Stripes" Associations Facilitate Later "Lion-Stripes" Learning, Deana Vitrano

Legacy Theses & Dissertations (2009 - 2024)

The current experiments examined Pyc and Rawson’s (2010) mediator effectiveness hypothesis (MEH) as one potential explanation of the beneficial effects of testing relative to restudying in paired-associate learning. In two experiments, participants learned cue-mediator-target triads (e.g., lion-tiger-stripes) broken down into separate components. Specifically, participants learned and then restudied or were tested on cue-mediator (List 1) and mediator-target (List 2) word pairs in Session 1, and in a Session 2 given 48 hours later learned cue-target (List 3) word pairs. According to Pyc and Rawson, compared to restudying, testing on List 1 cue-mediator and List 2 mediator-target word pairs should lead …

Effects Of Testing On Retroactive Interference And Proactive Interference In The A-B/A-C Paradigm, Stephanie Crocco

Legacy Theses & Dissertations (2009 - 2024)

In an A-B/A-C paradigm, testing A-B pairs before A-C learning reduces retroactive interference (RI, Halamish & Bjork, 2011) and proactive interference (PI, Wahlheim, 2015). In four experiments, after A-B and RI control pairs were studied in List 1, these pairs were either tested or restudied. A-C pairs and PI control pairs were then learned in List 2, followed by a final test on both lists or only List 1. Four procedural factors were manipulated: (1) Swahili-English pairs vs. weakly related English pairs, (2) List 1 restudy vs. test review between- vs. within-subjects, (3) some List 1 pairs studied vs. not …

When Is Test-Potentiated Learning Item-Specific Versus Generalized?, Carol Bolte

Legacy Theses & Dissertations (2009 - 2024)

The current experiments used short (< 1 min) and long (24-hour) retention intervals in the Test-Potentiated Learning (TPL) paradigm to investigate pair specific versus generalized testing effects (TEs) using weakly related English word pairs. The design of the present experiments improved the design used by Cho, Neely, Crocco, and Vitrano (2017), who used Swahili-English pairs. The present design allows for (a) an assessment of both between- and within-subjects pair-specific vs. generalized TEs within the same experiment and (b) better controlled comparisons of the pair-specific and generalized TEs. There was no TE at the short retention interval. At the long retention interval, the TE for tested pairs studied before and after the review test was greater than the generalized TEs obtained for (a) untested pairs studied before and after the review test and (b) untested pairs that were only studied after the review test. Thus, a pair-specific TE occurred, unlike in Cho et al. (2017). The potential reasons for why weakly related English word pairs show pair-specific TEs but Swahili-English pairs do not are discussed.

How Instruction, Math Anxiety, And Math Achievement Affect Learning A Novel Math Task: Evidence For Better Instruction, Amy Jane Mcauley

UNLV Theses, Dissertations, Professional Papers, and Capstones

The primary goal of this paper is to test how math anxiety, achievement, and instruction affect learning a novel math task. Currently, most research measures achievement and math anxiety on previously learned tasks. A two-part study was proposed to measure the effects of math anxiety on learning modular arithmetic (MA), a novel math task that involves subtraction and division. Participants of varying degrees of anxiety and achievement were randomly assigned to either a specific or vague instruction condition. Participants were either taught how to solve the task or given minimal information about how to solve the task. Before moving on, …

Manipulating Goal States And Brain States: Using Eeg And Hd-Tdcs To Investigate Mechanisms Underlying The Influence Of Achievement Goals On Declarative Memory, Yuliya Ochakovskaya

Dissertations, Theses, and Capstone Projects

When it comes to learning factual information, students may benefit from having opportunities where they can learn from their mistakes as opposed to only being asked to study that information. However, the achievement goals that instructors set for their students may influence how students engage with these learning opportunities. Although some instructors may focus students on learning (i.e. mastery goals), others may seek to motivate students by focusing them on doing better than others (i.e. performance goals), which is thought promote greater sensitivity to errors and impair learning. Across two studies, the present dissertation examined the roles of dorsolateral frontal …

Change Deafness: A Comprehensive Examinations, Vanessa Claire Irsik

UNLV Theses, Dissertations, Professional Papers, and Capstones

Environmental changes are a vital source of information which can drive advantageous behavioral responses. For example, detecting visual changes can be critical when driving a vehicle or when simply walking down a busy street. Auditory perception is an essential complement to vision as it can allow awareness of changes in and out of sight. While subjective perception would suggest that our sensory representation of the world is complete, research on change deafness indicates that quite often the opposite is true. Healthy listeners often miss salient, suprathreshold auditory changes. Three separate manuscripts will be presented, each of which aims to advance …
