The Influence Of Prediction Error Strength On Reconsolidation, Kevin D. Mohawk May 2023

The Influence Of Prediction Error Strength On Reconsolidation, Kevin D. Mohawk

UNLV Theses, Dissertations, Professional Papers, and Capstones

It has been well established that consolidated memories can be reactivated and enter a labile state where they are once again vulnerable to modification. Reactivated memories, therefore, need to be restabilized or reconsolidated. Prediction error (PE) is one of the most common ways of reactivating consolidated memories, yet no studies have examined how varying the strength of PE influences reconsolidation. The present study aimed to determine if the strength of PE is an important factor for triggering reconsolidation and if so, how PE strength influences the reconsolidation process, whether through strengthening or weakening the memory. To vary PE strength, participants …

The Effect Of Sleep And Emotion On Pattern Separation, Alanna N. Osmanski May 2023

The Effect Of Sleep And Emotion On Pattern Separation, Alanna N. Osmanski

UNLV Theses, Dissertations, Professional Papers, and Capstones

Prior work on the relationship between sleep and memory suggests that the sleep state is an optimal time for memory consolidation to occur. During slow wave sleep, newly encoded information in the hippocampus is repeatedly activated, driven by slow oscillations that originate in the neocortex. This process that occurs during slow wave sleep facilitates the long-term storage of memories. A widely accepted view of emotion and sleep is that emotional memories are preferentially consolidated during sleep so that they are easily accessible for retrieval, whereas neutral memories tend to be less accessible. However, recent meta-analyses of sleep, emotion, and memory …

Systemic Theoretical Instruction: Tense And Aspect In Italian A Sociocultural Study Of American Learners Of Italian, Charles Joseph Panarella, Jr. May 2023

Systemic Theoretical Instruction: Tense And Aspect In Italian A Sociocultural Study Of American Learners Of Italian, Charles Joseph Panarella, Jr.

UNLV Theses, Dissertations, Professional Papers, and Capstones

University-level language and second-language classrooms typically use general rules of thumb to teach grammar without considering its conceptual aspects and cultural origins. These general rules of thumb are normally taught using a communicative approach to language teaching which typically places little emphasis on immediate corrective feedback and learner development. Most assessments are static in nature and focus on right and wrong answers rather than their origins (i.e., learner development and microgenesis). The lack of corrective feedback and lack of considering affective factors have the potential to negatively influence language acquisition in terms of motivation and self-efficacy. In addition, foreign language …

Comparing Comics And Illustrated Texts In Multimedia Learning, Jackson S. Pelzner May 2023

Comparing Comics And Illustrated Texts In Multimedia Learning, Jackson S. Pelzner

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this research was to examine how different forms of media, in particular science comics and illustrated texts, contribute to different patterns of learning. While the standard illustrated text seen in a textbook has been a useful tool for instruction, science comics appear to be an alternative that could be used in lieu of media that use the traditional illustrated text format. The comic format, known more for its visual appeal to readers, is consistent with the principles of the Cognitive Theory of Multimedia Learning (Mayer, 2009), though comprehension may require different mechanisms (Cohn, 2013a). It was hypothesized …

Leveraging Simulation To Understand Nursing Student Learning In Technologically Complex Environment, Deborah Rojas May 2023

Leveraging Simulation To Understand Nursing Student Learning In Technologically Complex Environment, Deborah Rojas

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction The adoption of simulation technologies in schools of nursing has increased significantly over the last 5 years. Results regarding the use of simulation technology have been positive. The use of simulation technologies has been developed to include complex nursing situations that resemble real clinical settings. Research has demonstrated that memory recall is better in an environment that is the same or similar to the environment in which the learning took place (Krokos et al., 2018). For this reason, educators have used simulation technologies to create realistic environments where students can learn. However, learning outcomes in simulations are affected by …

Sight Words: Poems, Benjamin Harrison Socolofsky May 2023

Sight Words: Poems, Benjamin Harrison Socolofsky

UNLV Theses, Dissertations, Professional Papers, and Capstones

Sight Words is a collection of poems that questions the image as the central unit of meaning in poetry. Sight words is a lyric bildungsroman, that traces the process of metaphysical alienation that an individual undergoes in the postmodern world. The speaker is exposed to an overabundance of meaning that the visual world transmits and as the order of language deteriorates, meaning multiplies and falters. The language and poetics of Sight Words struggles to reconcile the disconnect between visual language and spoken language. Every missed communication points to a denial of access to the self, which the speaker apprehends as …

Examining The Effects Of Perspective-Taking And Empathetic Concern On Attractiveness Biases In Millennial And Generation X Adults, Stephanie Verba-Quinones May 2023

Examining The Effects Of Perspective-Taking And Empathetic Concern On Attractiveness Biases In Millennial And Generation X Adults, Stephanie Verba-Quinones

UNLV Theses, Dissertations, Professional Papers, and Capstones

The current study examined the effects of perspective-taking and empathetic concern on attractiveness biases and stereotypes in Generation X and Millennial adults. Such biases and stereotypes are pervasive and can lead to preferential treatment and differential outcomes for individuals of varying attractiveness levels (see Langlois et al., 2000 for review). Previous research suggests that social media may amplify the importance placed on attractiveness, particularly for women (Fardouly et al., 2015; Perloff, 2014; Tiggemann et al., 2014; Toma & Hancock, 2018). Given the negative impacts of biases and stereotypes, this study sought to investigate pathways to reduce attractiveness biases and stereotypes …

The In/Visible Stockade: Sex Offender Management, Governmentality, And The Search For Normal Life, Christopher Wakefield

UNLV Theses, Dissertations, Professional Papers, and Capstones

Over the past thirty-five years, the United States has seen a dramatic expansion of regulatory policy around individuals convicted of sexual offenses. Sex offender management policies include national and state registries, notification laws, treatment mandates, residency restrictions, and numerous exclusions from institutions. A growing body of research from sociologists and criminologists has tracked the effects of this sex offender regime by measuring recidivism and collateral consequences among released offenders. Less attention has been paid to how sex offenders adapt to their regulator context—especially the selective public visibility that the registry generates. Furthermore, sociological scholarship has not yet developed strong theoretical …

Development And Initial Validation Of The Mindful Self-Regulated Learning Scale (M-Srls), Sarah Wolff

UNLV Theses, Dissertations, Professional Papers, and Capstones

Modern mindfulness is a catch-all term. Just exactly what it looks like within the context of education and how it is taught vastly varies. As such, program fidelity and integrity is questioned. Here a definition of mindful self-regulated learning is proposed and the Mindful Self-Regulated Learning Scale (m-SRLS) is developed. This includes item generation and development, systematic testing of item performance, scale dimensionality, convergent and divergent validity, measurement invariance across groups and subgroups, and scale reliability over a series of five pilot studies and five primary studies using independent samples. The resulting m-SRLS is a context specific measurement tool that …

Systems Dynamics Of The Anterior Cingulate Cortex And Hippocampus In Behavioral Switching, Spatial Working Memory, And Disease, Ryan Wirt May 2023

Systems Dynamics Of The Anterior Cingulate Cortex And Hippocampus In Behavioral Switching, Spatial Working Memory, And Disease, Ryan Wirt

UNLV Theses, Dissertations, Professional Papers, and Capstones

The electrophysiological properties of the hippocampus (HC) and anterior cingulate cortex (ACC) are the central focus of research on learning, memory, and neurological disease. Previous research has shown that HC is essential for forming new memories, spatial navigation, and temporal processing. While the function of ACC, located within the medial prefrontal cortex, remains controversial, it has a role in long-term memory recall, processing pain, monitoring current state, learning, schema updates, and information integrations. Interactions between the ACC and HC occur during social memory, spatial working memory performance, and long-term memory recall. Notably, the HC and ACC are among the first …

Congruences For Quotients Of Rogers-Ramanujan Functions, Maria Del Rosario Valencia Arevalo May 2023

Congruences For Quotients Of Rogers-Ramanujan Functions, Maria Del Rosario Valencia Arevalo

Theses and Dissertations

In 1919 the mathematician Srinivasa Ramanujan conjectured congruences for the partition function p(n) modulo powers of the primes 5,7,11. In this work, we study Ramanujan type congruences modulo powers of primes p = 7,11,13,17,19,23 satisfied by the Fourier coefficients of quotients the Rogers-Ramanujan Functions G(τ) and H(τ) and the Dedekind eta function η(5τ). In addition to deriving new congruences, we develop the foundational theory of modular forms to motivate and prove the results. The work includes proofs of congruences facilitated by Python/SageMath code.

Characterizing Energy Dissipation Of Shallow-Water Wave Breaking In A Storm Surge, Hunter Boswell, Guirong Grace Yan, Wouter Mostert

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

While understanding breaking waves is crucial for the development of parametrizations used in ocean wave modeling for both deep and shallow water, the complete process of wave breaking is not well understood. Here we present direct numerical simulations of two-dimensional solitary waves that shoal and break on a uniform beach in shallow water, with the presence of storm surge represented by an inshore region. The storm surge depth, beach slope, and wave amplitude are varied to study the dependence of energy dissipation in the breaker on wave and bathymetric parameters. We classify wave breaker types and find a separation between …
