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 …

A Study Of Flight Simulation Training Time, Aircraft Training Time, And Pilot Competence As Measured By The Naval Standard Score, Aaron D. Judy

Doctor of Education (Ed.D)

The purpose of the study was to investigate the relationships between US Navy T-45C flight simulation training time, actual aircraft training time, and intermediate and advanced jet pilot competence as measured by the Naval Standard Score (NSS). Examining the relationships between US Navy T-45C flight simulation time and actual aircraft flight time may provide further information on flight simulation training versus actual aircraft training to aviation authorities, flight instructors, the military aviation community, the commercial aviation community, and academia. The study was non-experimental, correlational, causal-comparative with an emphasis upon the establishment of mathematic and predictive relationships using archival data from …

Motivational Valence Alters Memory Formation Without Altering Exploration Of A Real-Life Spatial Environment, Kimberly S. Chiew, Jordan Hashemi, Lee K. Gans, Laura Lerebours, Nathaniel J. Clement, Mai-Anh T. Vu, Guillermo Sapiro, Nicole E. Heller, R. Alison Adcock

Psychology: Faculty Scholarship

Volitional exploration and learning are key to adaptive behavior, yet their characterization remains a complex problem for cognitive science. Exploration has been posited as a mechanism by which motivation promotes memory, but this relationship is not well-understood, in part because novel stimuli that motivate exploration also reliably elicit changes in neuromodulatory brain systems that directly alter memory formation, via effects on neural plasticity. To deconfound interrelationships between motivation, exploration, and memory formation we manipulated motivational state prior to entering a spatial context, measured exploratory responses to the context and novel stimuli within it, and then examined motivation and exploration as …

Towards Improving Learning With Consumer-Grade, Closed-Loop, Electroencephalographic Neurofeedback, Zall Soren Hirschstein

Senior Projects Spring 2018

Learning is an enigmatic process composed of a multitude of cognitive systems that are functionally and neuroanatomically distinct. Nevertheless, two undeniable pillars which underpin learning are attention and memory; to learn, one must attend, and maintain a representation of, an event. Psychological and neuroscientific technologies that permit researchers to “mind-read” have revealed much about the dynamics of these distinct processes that contribute to learning. This investigation first outlines the cognitive pillars which support learning and the technologies that permit such an understanding. It then employs a novel task—the amSMART paradigm—with the goal of building a real-time, closed-loop, electroencephalographic (EEG) neurofeedback …

Assessing The Implicitness Of Visual Statistical Learning At The Individual Level, Derek Mcclellan

Online Theses and Dissertations

Previous research has examined visual-statistical learning at the individual level but have used measurements which are not sensitive enough to detect differences at the individual level. This study investigates temporal visual-statistical learning but uses a recently modified task designed to be more sensitive to individual performance. This study also incorporated an indirect measure of learning in the form of a rapid serial visual presentation paradigm (RSVP), a cover task, and binary confidence judgments, to assess how aware participants were of the statistical structure. Although there was strong evidence of participants learning the statistical structure at the group level, there was …

The Domain-Generality And Durability Of Efficient Learning, Christopher Zerr

Arts & Sciences Electronic Theses and Dissertations

People differ in how quickly they learn information and how long they remember it, and a common finding in the literature is that a quicker rate of learning coincides with better retention for the learned material. Zerr and colleagues (2017) termed the relation between learning rate and retention as learning efficiency, with more efficient learning representing both a faster acquisition rate and better memory performance after a delay. Zerr et al. also demonstrated in separate experiments that how efficiently someone learns is stable across a range of days and years. The current thesis includes two experiments addressing additional questions …

An Examination Of Accessible Hands-On Science Learning Experiences, Self-Confidence In One’S Capacity To Function In The Sciences, And Motivation And Interest In Scientific Studies And Careers., Mick D. Isaacson, Cary Supalo, Michelle Michaels, Alan Roth

Journal of Science Education for Students with Disabilities

This study examined the potential relationship of accessible hands-on science learning experiences to the development of positive beliefs concerning one’s capacity to function in the sciences and motivation to consider science as a college major and career. Findings from Likert survey items given before and after engaging in accessible hands-on science laboratories show that students who were blind or had low vision (BLV) were more likely to agree with the following items after engaging in accessible science experiences: 1) I plan on enrolling as a science major in college; 2) My educational experiences, so far, have given me the …

Recognition Training For Faces Across Age Gaps, William Blake Erickson

Graduate Theses and Dissertations

Face recognition is a problem that has theoretical and applied value. However, the fact of facial aging is rarely addressed in research and unmentioned in the major theories of face recognition. Facial aging also has ramifications for missing persons and fugitive cases, confounding attempts by law enforcement to recover these people whose last known images are years or decades out of date. This dissertation reports three studies aimed at measuring baseline age-gap recognition ability and testing various training regimens designed to increase accuracy rates for this unique kind of recognition task.

Mechanisms Responsible For The Development Of Causal Perception In Infancy., Nicholas A. Holt

Electronic Theses and Dissertations

The aim of the current dissertation was to investigate the mechanisms that contribute to the emergence of causal perception in infancy. Previous research suggests that the experience of self-produced causal action may be necessary to promote the development of causal perception (Rakison & Krogh, 2012). The goal of the current study was two-fold: (1) to further explore the roles of self-produced action, haptic, proprioceptive and visual information, and parental interaction on young infants’ understanding of causality. To assess the impact of these factors on infants’ causal learning, 4½-month-olds were randomly assigned to one four conditions. Three of the conditions (Active …

Dancing In The Dark: Sleep-Dependent Motor Skill Memory Consolidation And Periodic Limb Movement Disorder, Valya Sergeeva

Electronic Thesis and Dissertation Repository

Periodic Limb Movement Disorder (PLMD) is a neurodegenerative disease characterized by dysfunction of the striatum and brief, repetitive limb movements during sleep. PLMD can severely disrupt non-rapid eye movement (NREM) sleep. Motor skills learning and memory consolidation are dependent on striatal activation, the latter enhanced by NREM sleep. Therefore, we investigated whether individuals with PLMD had learning and sleep-related memory deficits, and whether this putative deficit was related to sleep quality or symptom severity. 14 adults with a PLM index >15/hr underwent two nights (baseline, training) of polysomnographic recording. 15 age-matched healthy controls underwent three nights (baseline, undisturbed training and …

An Analysis Of Canine Processing Of Stimulus Compounds Varying In Light And Sound Intensity, Katherine O. Compitus

Theses and Dissertations

A dog was trained to respond deferentially to two light-sound compounds. The dog was then tested with combinations of additional light and sound intensities. The dog appeared to use the information provided by both stimulus dimensions. This research is relevant to the understanding of information processing, specifically categorization and generalization.

Practical Implications Of Learning From Unsuccessful Retrieval Attempts, Ann C. Rossmiller, James R. Houston

Williams Honors College, Honors Research Projects

Recent findings suggest that retesting oneself facilitates better learning than studying alone. Building off previous experiments where correcting participants has significantly increased correctness, the current study furthers our understanding about learning from unsuccessful retrieval attempts by manipulating the frequency of correction. Using a set of 42 associated word pairings, each participant was exposed to two blocks where they would memorize the word pairs. This was followed by two quizzing blocks and a final exam block where participants were asked to write down the associate to the stimulus presented on screen. Frequency of correction was manipulated during the quizzing blocks where …

Variable Semantic Input And Novel First-Language Vocabulary Learning, Nichole Runge

Arts & Sciences Electronic Theses and Dissertations

Vocabulary learning involves mapping a word form to a semantic meaning. An individual asked to learn the Spanish word for “apple,” for example, must map a new word form (manzana) onto the appropriate semantic representation. Previous studies have found that acoustic variability of word forms can improve second language vocabulary acquisition (Barcroft & Sommers, 2005; Sommers & Barcroft, 2007). The current experiments investigated whether variable semantic input could have a similar beneficial effect on first language vocabulary learning. Participants learned low-frequency English vocabulary words and their definitions. Half of the words were shown with the same verbatim definition …

Fluid Grouping: Quantifying Group Engagement Around Interactive Tabletop Exhibits In The Wild, Florian Block, James Hammerman, Michael Horn, Amy Spiegel, Jonathan Christiansen, Brenda Phillips, Judy Diamond, E Margret Evans, Chia Shen

Department of Educational Psychology: Faculty Publications

Interactive surfaces are increasingly common in museums and other informal learning environments where they are seen as a medium for promoting social engagement. However, despite their increasing prevalence, we know very little about factors that contribute to collaboration and learning around interactive surfaces. In this paper we present analyses of visitor engagement around several multi-touch tabletop science exhibits. Observations of 629 visitors were collected through two widely used techniques: video study and shadowing. We make four contributions: 1) we present an algorithm for identifying groups within a dynamic flow of visitors through an exhibit hall; 2) we present measures of …

Learning Requires Attention For Binding Affective Reinforcement To Information Content, Chia Mun Foo

Scripps Senior Theses

Humans are limited in their capacity to process information about the environment; to choose the most salient details to process, we have to make rapid value appraisals and prioritize our attentional resources. In this proposed study, it is expected that attention is required to learn from affective information. Learning is measured by the difference between update (the difference between the first and second estimation) and the estimation error (the difference between the average likelihood and the first estimation). Using a belief-updating paradigm, participants will be asked to estimate their likelihood of encountering a negative event, once before and once after …

Cortisol Levels And Voltage Conditions Of College Students, Adriana Steffens

Walden Dissertations and Doctoral Studies

There is a limited research base on low voltage brain conditions, which are characterized by electrical activity being measured at below 20 microvolts. The purpose of this study was to examine the relationship between saliva cortisol levels and voltage using an EGG in a college student population. Illuminating this relationship is important to inform how low voltage conditions can affect daily memory and cognitive functioning of undergraduate college students that may be a result of stress. The college student population may be vulnerable to the low voltage condition because of stress from the transition between teenage and adult life and …

Implicit Theories Of Intelligence And Learning A Novel Mathematics Task, Nathan Oehme Rudig

UNLV Theses, Dissertations, Professional Papers, and Capstones

The social-cognitive model of motivation states that students adopt a theory of the nature of intelligence that guides their goals in academia and their responses to academic setbacks. Students who believe intelligence is an unchanging entity within them are more likely to adopt goals to display high ability, hide low ability, and respond helplessly to failed schoolwork. Conversely, a student who believes intelligence is a measure of effort and persistence will be motivated to gather knowledge and acquire new skills. The current study investigated the role theories of intelligence play in the field of mathematics understanding. In two experiments, participants …

The Formation Of Situation Models In Multimedia, Kris Gunawan

UNLV Theses, Dissertations, Professional Papers, and Capstones

When people read traditional text-based stories, they construct mental representations of the described state of affairs, called situation models, to connect various details of events (e.g., time, space, entity) in memory (Zwaan & Radvansky, 1998). According to the cognitive theory of multimedia learning (Mayer, 2005; 2011), stories presented as pictures and text generate independent channels of mental representations that can work hand-in-hand or separately to acquire and remember the materials presented. This dissertation consisted of two experiments that were used to further explore how the two modalities affect what is being mentally represented in memory. In Experiment 1, participants were …

Examining The Testing Effect Using The Dual-Process Signal Detection Model, Nicole Jessica Bies-Hernandez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Taking a test can lead to enhanced long-term retention compared to not practicing the information or simply restudying, a finding known as the testing effect (Roediger, Agarwal, Kang, & Marsh, 2010). The current study examined whether the dual-process signal detection (DPSD) model (Yonelinas, 1994) offers an approach for investigating the testing effect across two experiments. Experiment 1 investigated if the DPSD model could be used to examine the testing effect, and it also examined a factor (i.e., the number of practice sessions) that influences the magnitude of the testing effect. Experiment 2 investigated whether making the final test dependent on …

Skill Acquisition And The Influence Of Attentional Focus And Practice, Alison Beth Regal

Dissertations, Master's Theses and Master's Reports - Open

Attentional focus and practice schedules are important components in learning a new skill. For attention this includes focusing inward or outward, for practice this includes interference between tasks. Little is known about how the two interact. Four groups; blocked/extraneous (BE); blocked/skill-focused (BS); random/extraneous (RE); and random/skill-focused (RS), practiced 100 trials of golf putting and 64 trials of a key-pressing task in addition to responding to a random tone distracting attention towards or away from skill movement. Participants performed immediate and delayed retention tests. Results demonstrated the BE group had decreased RTE scores compared to the BS group. Immediate retention demonstrated …

Modelling Biased Judgement With Weighted Updating, Jesse A. Zinn

Jesse A Zinn

The weighted updating model is a generalization of Bayesian updating that allows for biased beliefs by weighting the functions that constitute Bayes’ rule with real exponents. This paper shows that weighting a distribution affects the information entropy of the resulting distribution, suggesting that weighted updating can model biases in which individuals mistake the information content of data. The paper augments the base model in two ways, allowing it to account for additional biases. The first expansion involves discrimination between data. The second allows the weights to vary over time. The paper also presents a set of sufficient conditions for the …

Explicit Learning In Down Syndrome: A Cross-Sectional Developmental Trajectory Approach, B. Allyson Phillips

Books and Monographs

The purpose of the current study was to analyze the cross-sectional developmental trajectories of explicit category learning in individuals with Down syndrome compared to individuals with intellectual disability and typically developing individuals. Explicit learning is active, conscious, controlled, and intentional; it is a deliberate attempt to acquire new knowledge or skill from repeated tries with feedback. Explicit learning improves with age throughout childhood and is closely related to intelligence. Because of its relation to intelligence, we expected individuals with Down syndrome to perform below the level expected for their chronological age and nonverbal ability.

The sample was comprised of 41 …
