The Role Of 5-Ht6 Receptor Activation In Learning Consolidation, Jasmine Alyssa Robinson

Electronic Theses, Projects, and Dissertations

The focus on serotonergic dysfunction as a contributor to cognitive deficits in disorders such as autism spectrum disorder, Alzheimer's disease, and schizophrenia drives researchers to investigate the functional impact of specific serotonin receptor types on executive functioning. By discerning the potential enhancement or impairment effects, this endeavor seeks to unravel the complex interplay between serotonin receptors and cognitive abilities. Specifically, within the three domains of learning, acquisition, consolidation, and retrieval, we find serotonergic modulation to be pivotal. Recent studies have highlighted the 5-HT6 receptor as a novel target for cognitive enhancement. However, the majority of the research investigates the effects …

Does Pleasurable Music Indirectly Better Learning?: A Multimodal Approach, Elizabeth Anna Roeglin

Undergraduate Honors Papers

Recent research has shown that musical pleasure is due to the combination of uncertainty and surprise a musical piece elicits. Additionally, research has demonstrated that music influences arousal and mood, both of which affect learning. However, current research has not adequately tested whether pleasurable music indirectly improves learning by influencing mood/arousal. This study attempts to do so. Twenty-seven participants completed a survey that included the Barcelona Music Reward Questionnaire. Eighteen participants, whose scores demonstrated that they feel emotion-evoking and/or mood-regulatory pleasure from listening to music, came in for further testing. These participants experienced a music condition, in which they listened …

The Role Of Glutamate In The Medial Prefrontal Cortex In The Acquistion And Expression Of Conditioned Approach, Rudolf Nisanov

Dissertations, Theses, and Capstone Projects

A series of experiments were conducted to assess the role of glutamatergic stimulation in the dorsal and ventral regions of the medial prefrontal cortex (mPFC) in both the acquisition and expression of reward-related learning using a Pavlovian conditioning paradigm, the conditioned-approach paradigm. Rats with surgically implanted cannulas were exposed to Pavlovian conditioning sessions that occurred on three alternative days (acquisition) or seven consecutive days (expression). These 60-min conditioning sessions consisted of 30 pairings of light (CS) and food pellets (US) presented under a random time schedule. After a two-day break, rats underwent a session with no CS or US and …

Building Technology Breaks Into Classroom Instruction To Reduce Media Multitasking And Increase Learning, Lisa Decicco

PCOM Psychology Dissertations

The current study was designed to investigate the impact of media multitasking on learning outcomes in the classroom. The goal was to develop an instructional intervention that reduces the negative effects of media multitasking on learning outcomes by incorporating technology breaks into the instructional design. High school students in an all-girls school took part in three learning sessions, each with a different instructional strategy related to media multitasking in the classroom: Condition 1: Instruction as Usual; Condition 2: No access to technology; Condition 3: Technology Breaks. Students completed a pre and post-test knowledge-based assessment to measure their retention of the …

One group of students (n = 30) received mindfulness training while the acted as an active control group (n = 30) and received study skills training. Both groups received 20-minutes training in their English classes, four days a week, for 4-weeks. All participants …

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 …

​​The Effects Of Viewpoint, Motion, And Affordance Priming On Perceptual Learning Of Feelies​, Catherine Dowell

Dissertations

According to Gibson and Gibson (1955) perceptual learning is a process of developing the skill to differentiate previously undifferentiated but available information. The initial investigations focused on object identification, lacking a behaviorally relevant functional task. In the current study participants learned to differentiate between novel objects (feelies). To test the role of visual exploration objects were viewed from either a side or a top view and were displayed as either static pictures or rotating about a vertical axis. In Experiment 1 a simple object discrimination task was used. Perfect accuracy was achieved sooner in static conditions compared to motion conditions …

Motor Milestone Acquisition And Sleep-Related Learning And Development In Infancy, Aaron Demasi

Dissertations, Theses, and Capstone Projects

The aim of this dissertation is to summarize and extend work in the field of infant sleep and motor development. Chapter 1 summarizes what is currently known about typical infant sleep development and the way that sleep impacts learning throughout infancy. Chapter 2 describes two experiments showing the importance of napping and night sleep in the consolidation of gross motor learning. Given that sleep is beneficial for learning throughout human infancy, the remainder of the dissertation investigates how learning (in this case, motor development) impacts sleep. Chapter 3 establishes the possible role of sleep-dependent movement in sleep disruption resulting from …

The Impact Of Immersive Vr Verses Desktop Vr Technologies On Learning Attainment And Sense Of Presence, Haley Renee Hoffman

Dissertations and Theses

The study examined the influence of immersive technologies and sense of presence on learning outcomes while comparing different media formats (Immersive Virtual Reality and Desktop Virtual Reality). The experiment was conducted on N=68 students that experienced a biology lesson about the human cellular system and its related processes. The current literature suggests that Immersive technologies can a powerful impact to learning, but it is crucial to identify when and how these impacts emerge. The current assumption is that presence and educational outcomes stem from the amount of engagement with the material, which is suggested to depend on the level of …

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 …

Critical Literacy: Meeting Twenty-First Century Literacy Demands For Adolescent Learners, Molly Blew

PCOM Psychology Dissertations

Adolescents’ critical text interpretation skills are important to college, career, and citizenship demands. At present, the literature reflects concerns with adolescents’ ability to interpret academic and internet-based texts critically. The pedagogical framework of critical literacy is presented as an instructional approach that may support the development of adolescents’ critical text interpretation skills. The objective of this study was to understand the perceptions of secondary teachers concerning student proficiency in critical text interpretation, teachers’ current level of implementation of instructional practices consistent with the critical literacy framework, and perceived barriers to implementation. Three hundred thirty four (334) high school teachers were …

Culturally Responsive Evaluation Methods In Philanthropy: Striving For Community Inclusion Amidst Power Hoarding Practices, Cristina Elena-Tangonan Whyte

CGU Theses & Dissertations

The importance of culture in the field of evaluation can be observed through the advancements that culturally responsive evaluation (CRE) and culturally responsive equitable evaluation (CREE) scholars have made in this arena over the past few decades. The literature, however, still lacks close examination of how CRE approaches are applied in institutions where cultural bias exists, such as philanthropy. Few researchers have examined the biases present in partnering with funders, white dominant norms, and the extent to which these elements facilitate or inhibit community inclusion in CRE. To address this gap, the present study utilized an exploratory sequential mixed methods …

The Role Of Dentate Gyrus Pituitary Adenylate Cyclase Activating Polypeptide (Pacap) In Contextual Fear Discrimination, Samantha Kelly Moriarty

Graduate College Dissertations and Theses

When dysregulated, neural systems important for fear behaviors can contribute to mental health disorders such as anxiety, phobias, and post-traumatic stress disorder (PTSD). In PTSD, a myriad of symptoms is possible, but a hallmark feature of the disorder is generalizing fear. This occurs when fear is experienced inappropriately in relation to the environment or circumstances. To study this behavior in rodent models, contextual fear conditioning is used. Contextual fear conditioning is a learning theory preparation where rodents are conditioned with an aversive stimulus such as foot-shock in one distinct context (A), while concurrently being exposed to a safe context (B). …

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 …

The Neurotic Wandering Mind And Self-Efficacy During Training, Mario L. Arredondo

Legacy Theses & Dissertations (2009 - 2024)

AbstractPersonality is complex and dynamic, and because this attribute consists of a cluster of different distinctive traits, successfully predicting how personality predisposes individuals to different reactions and feelings during a learning activity is an equally complex and challenging task. For this thesis I will focus on the personality trait of low emotional stability, or neuroticism. Previous research has shown that people with lower emotional stability have a predisposition to be more stringent with self-perceptions across different domains of behaviors and feelings. Self-efficacy influences people’s confidence in their ability to exert control over their own behavior and impact their environment, all …

Developmental Differences In The Learning And Consolidation Of Linguistic Regularities, Sarah Berger

Electronic Thesis and Dissertation Repository

Relative to adults, children have a well-known advantage for learning linguistic regularities, which could be partially driven by their deeper sleep. To examine the relationship between consolidation and language learning across development, children and adults learned a novel article system with an implicit grammatical rule. Participants performed a judgment task on phrases containing the novel articles before and after a night of EEG-monitored sleep. We found that rule sensitivity emerged rapidly in children, whereas it did not emerge until the second session in adults. Children demonstrated better generalization of the rule than adults. Consolidation effects showed a developmental double dissociation, …

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 Honors 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 …

Testing Models Of Context-Dependent Outcome Encoding In Reinforcement Learning, William M. Hayes Iv

Theses and Dissertations

Previous studies of reinforcement learning (RL) have established that choice outcomes are encoded in a context-dependent fashion. Several computational models have been proposed to explain context-dependent encoding, including reference point centering and range adaptation models. The former assumes that outcomes are centered around a running estimate of the average reward in each choice context, while the latter assumes that outcomes are compared to the minimum reward and then scaled by an estimate of the range of outcomes in each choice context. However, there are other computational mechanisms that can explain context dependence in RL. In the present study, a frequency …

Mapping Learning Ecologies: A Diffractive Exploration Of The Emergence Of Learning, Laurie Hurson

Dissertations, Theses, and Capstone Projects

In this dissertation, drawing on Karen Barad’s theory of agential realism (2007), I explore the learning ecology as a “specific material configuration” that produces learning, an emergent, “onto-epistemological” phenomenon of entangled being-knowing. I offer a new materialist approach to the learning ecology to better define the concept, taking seriously the material nature of the ecology and acknowledging that learning and knowing is a material practice of being in the world.

To explore learning ecologies, I conducted qualitative interview and mapping sessions with 26 undergraduate students at the City University of New York. To analyze the narrative and visual data, I …

Constructing Engineering Knowledge Through Tinkering, Reflection, And Digital Storytelling, Lauren C. Pagano

Dissertations

Educators and researchers suggest that informal learning activities in museums, libraries, and families’ homes can promote children’s science, technology, engineering, and mathematics (STEM) learning (Sobel & Jipson, 2016). Tinkering, a form of hands-on problem-solving involving real tools and materials, is one way to engage families in engineering design processes. However, tinkering activities vary greatly in terms of the goals presented, the resources available, and opportunities to test (Bevan, 2017). Across three studies, we examined how variations in tinkering exhibit design and parent-child interaction relate to children’s memory and STEM learning. In Study 1, we examined the structure and content of …

Relationships Between Executive Functioning, Memory, And Source Judgements On Children’S Responses To Online Advertising, Samantha Barbosa

Theses and Dissertations (Comprehensive)

Children’s understanding of online content is a topic of interest, yet little is known about how children distinguish distracting and often misleading information (e.g., advertisements) from relevant information. Our aim is to measure the relationship between executive functioning, memory and source monitoring in a population that has heavy internet usage and are also the most at risk for mistakenly recalling false or irrelevant information. Children aged 7-12 years old (N = 30), with no known developmental or cognitive disorders, were recruited for the study. In an online session, the children viewed two novel online media sources (i.e., a website …

Contributions Of Reward Identity And Time Prediction Errors To Pavlovian Learning, Daniel B. Siegel

Dissertations, Theses, and Capstone Projects

Some models of associative learning attempt to explain effects such as blocking and unblocking as reflecting a prediction error (PE): Associative strength, and thereby learning, are said to be greater when the unconditioned stimulus (US) received following a cue deviates from one’s expectations. Some models of PE-motivated behavior and PE-relevant brain activity represent the US as a single quantitative variable for outcome value, and that learning therefore only occurs when outcome value differs from expectations. There is growing evidence to suggest that changes in other dimensions of reward, such as identity and timing, also contribute to learning. In Experiment 1, …

Closing The Loop And Opening The Possibilities: Augmenting Sleep-Dependent Consolidation To Improve Long Term Memory, Aaron Paul Jones

Psychology ETDs

Memory consolidation occurs during slow-wave sleep. This is a complex process that can be studied using electroencephalography (EEG) and modulated with brain stimulation. Previous studies have shown that transcranial alternating current stimulation (tACS) can be used to entrain or disrupt endogenous oscillations in cortical networks and can be used for the manipulation of consolidation processes during sleep. In this series of experiments, sleep-dependent memory consolidation was modulated using closed-loop tACS (CL-tACS to improve memory performance for three tasks: a verbal paired associates task (PAT), an interference paired associates task (iPAT), and a visual category learning task. EEG was collected during …

Learned But Not Distracting: Low-Value Stimuli And Value-Driven Attentional Capture, John Albanese

Senior Theses and Projects

Stimuli previously associated with reward slow response times (RTs) when presented as irrelevant distractors in subsequent, unrewarded tasks (value driven attentional capture, VDAC). Typical VDAC training requires search for one of two experimentally-determined, colored circles and an orientation judgement of a line inside the color-defined target. Reward follows correct responses, associating high- or low-value with specific colors. Distractors rendered in high-value colors consistently slow RTs in an unrewarded test phase, an outcome that is rarely observed for low-value colors. Might this be due to a failure to adequately learn the reward contingencies during training? 22 observers underwent a modified training …

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 …

Mapping Out Learning: How Aerobic Exercise, Sex And Alzheimer's Disease Impact Learning, Grace G. Bouker

Senior Independent Study Theses

Exercise has the power to ameliorate the outward symptoms of Alzheimer’s Disease (AD) by rescuing hippocampal-dependent learning and memory. The goal of this research was to map out how exercise and sex impact behavioral learning in AD mouse models by looking outside of the traditional measurements in the Morris water maze (MWM), as they fail to describe the process of learning itself. I calculated heading error at maximum velocity, manually categorized search strategy in the MWM across trials, and determined flexibility in the probe trial for transgenic and wild-type mice who were exposed to exercise or control housing. Mice significantly …

The Effect That Testing Has On Nondeclarative Memory, David Smith

Electronic Theses and Dissertations

Testing has been shown to improve long-term memory retention by decreasing the amount of material forgotten, a phenomenon known as the testing effect. This positive impact of testing has been shown using direct tests of memory that require declarative memory, things like memorizing word-pairs and single-word lists. This dissertation is the first research to investigate how testing impacts nondeclarative memory using three experiments. The first and second experiment utilize the word fragment completion task to measure the effect that testing has on words learned via methodology thought to recruit either declarative or nondeclarative memory. The third experiment utilizes a probabilistic …
