Modeling Distribution Learning In Visual Search, Andrey Chetverikov

MODVIS Workshop

Chetverikov, Campana, and Kristjansson (2017) used visual search to demonstrate that human observers are able to extract statistical distributions of visual features. Observers searched for an odd-one-out target with distractors randomly drawn from the same distribution over the course of several “prime” trials. Then, on test trials parameters of the target and distractors changed and response times (RT) were analyzed as a function of the distance between the target position in feature space and the mean of distractor features during prime trials. The resulting RT curves followed the probability density of prime distractor distributions. This approach provides a detailed estimation …

Down Syndrome, The Image Of God, And Personhood, Paris Webb

Dialogue & Nexus

People with Down syndrome help Christians understand what being made in the image of God truly means. After describing Down syndrome, we will examine the different views of the image of God and how these relate to people with Down syndrome. Another approach will be to define personhood in light of God’s image and relate it to Down syndrome. We will use the principles held by the L’Arche community as an exemplar in this discussion to demonstrate that those with Down syndrome encourage us to expand our understanding of the image of God. Consequently, Down’s persons allow us to apply …

Modeling The Neural Circuitry Underlying The Behavioral And Eeg Correlates Of Attentional Capture, Chloe Callahan-Flintoft, Brad Wyble

MODVIS Workshop

The Reactive-Convergent Gradient Field model (R-CGF) is a unique approach to modeling spatial attention in that it links neural mechanisms to event related potentials (ERPs) from scalp EEG. This model was developed with the aim of explaining different, sometimes conflicting, findings in the attention literature. Specifically, this model address conflicting findings showing both simultaneous and serial deployment of attention. Another argument addressed by the model is whether attention to a location invokes a suppression of the spatial surround, or the selective inhibition of distractors. With the R-CGF, we have found that these results are not as incompatible as they appear …

Age-Related Changes In Visual Spatial Performance, Samantha Farrell

Seton Hall University Dissertations and Theses (ETDs)

Visual spatial skills allow individuals to understand the relationship between objects, people, and the environment for their everyday activities. Visual spatial abilities incorporate visual, motor, and cognitive components, each of which changes across the lifespan. The current study examined the effects of age-related changes and practice type on visual spatial performance. Participants between 40 and 79 years of age were asked to complete the Block Design Task (BDT) by using nine blocks to recreate various designs. Both accuracy and latency were measured to examine these changes. Task difficulty and practice type were varied and cognitive abilities were measured via MMSE …

The Developmental Progression Of Cognitive Abilities In Deaf Children, Jacqueline N. Wunderlich

Undergraduate University Honors Capstones

Although there has been a copious amount of research on deaf children’s language acquisition and academic abilities, our knowledge concerning the development of nonverbal cognitive functioning in this population remains limited. The Rey-Osterrieth Complex Figure (ROCF) is a commonly used neuropsychological tool for the assessment of visuospatial, visuoconstructional, visuomemory, and executive functioning abilities. As a language-reduced test, it seems ideal for use with deaf children. Previous studies using different scoring systems indicate that deaf children perform average to slightly above average on the ROCF compared with hearing youth. However, minimal normative data and established cognitive developmental patterns for deaf children …

Individual And Group Differences In Sound Category Learning, Ben Carlstrom

Student Research Symposium

Abstract: We examined the role of procedural-, declarative-, and working-memory systems in adults learning novel sound categories. Adults have fully developed declarative-memory skills that sometimes inhibit their ability to learn implicitly/procedurally (Filoteo, Lauritzen, & Maddox, 2010). Models of impaired language like the Procedural Deficit Hypothesis suggest that procedural-memory deficits are predictive of language-learning outcomes (Lum, Conti-Ramsden, Page, & Ullman, 2011). This study tested the hypothesis that language structure is best learned implicitly/procedurally, which has implications for L2 learning and language impairment. The novel sound categories presented to participants varied along a phonologically non-native dimension, pitch, and a native dimension, vowel …

Mindfulness Meditation As A Stress Reactivity Intervention: An Event-Related Potential Study, Jessica L. Trottier, Barry S. Oken

Student Research Symposium

The biological and neural mechanisms of stress have been extensively studied and supported, but are still unclear. Event-related potentials (ERP’s) emitted by neurons in the brain are a useful tool in measuring stress because they reflect neural response in real-time, to the millisecond, versus typical biological markers, which are typically evaluated before and after a stress test. The neurobiological relationship between ERP’s and stress originates in the anterior cingulate cortex, which in turn activates the hypothalamic–pituitary–adrenal axis; the main physiological cascade fueling the stress response and its chronically harmful symptoms. Malfunctions in the stress response, as in the cases of …

Associations Between The Willingness To Exert Cognitive Effort And Smoking Abstinence, Austin A. Phanouvong

Student Research Symposium

In decision-making tasks, individuals who prefer smaller, immediate rewards over larger, delayed rewards (delay discounting) are less likely to quit smoking. Indeed, decision-making tasks with delayed reward costs are sensitive to many aspects of substance use disorders. However, other reward costs might also be important. Our study focused on one of these other reward costs, which was cognitive effort (CE). 22 current smokers who were anticipating quitting in the near future were recruited to validate if more CE discounting predicted shorter abstinence times in reinforced smoking lapse period. Each participant had to be over the age of 21, and smoke …

Multilingualism And Ego Depletion In Interference Task Performance – Are Multilingual Brains More Intelligent Than Monolingual Brains?, Dorota B. Botwina

Theses and Dissertations

Research linking multilingualism with better executive control has produced inconsistent findings. Since definitive empirical evidence is not available, this study seeks to explore whether these advantages really exist. The Flanker Task followed an ego depletion task that was introduced to participants who were monolingual, bilingual and trilingual.

Does Genotype Correlate With Phenotype? Evaluating Ruffed Lemur (Varecia Spp.) Color Vision Using Subject Mediated Automatic Remote Testing Apparatus (Smarta), Raymond Vagell

Theses and Dissertations

Ruffed lemur (Varecia spp.) color vision research was conducted using a multidisciplinary approach: psychophysics, genetic analysis, technology, and animal training. The behavioral manifestation of Varecia spp. trichromacy was shown using a touchscreen apparatus (SMARTA). Trichromats performed better than dichromats when discriminating red from green (G₂ = 78.10, p < 0.001).

The Effects Of Pointing Gestures On Visual Attention, Samaria J. Hamilton

Honors College Theses

Visual attention is a process that involves concentrating on select features, such as sensory cues, within the complex environment. Sensory cues within the visual field capture and redirect our attention. Previous research on eye gaze revealed that direct gaze captures attention. In the present study, pointing gestures and motion cues were tested together in a visual search task to examine their effects on attention. Participants were instructed to identify a target letter presented on one of four hands. Initially, two hands displayed a pointing gesture while the other two displayed an open gesture. Next, a target letter appeared, one open …

The Role Of Stereotype Threat In Mental Rotation, Bridget A. Parler

All NMU Master's Theses

Numerous studies have been conducted on mental rotation ability in both males and females. A lot of the literature discusses male superiority in mental rotation task as opposed to females. This paper examined the role of stereotype threat in a mental rotation task. Particularly, the research study focused on gender stereotype threat in female college students. The study was completed in a two part design with students completing two mental rotation task in a group setting. The low numbers in the sample make it impossible to reliably say that the Vandenberg Mental Rotation Task (VMRT) and the Purdue Mental Rotation …

Literacy Revolution: How The New Tools Of Communication Change The Stories We Tell, Molly Gamble

Dissertations, Masters Theses, Capstones, and Culminating Projects

The transmission of culture depends upon every generation reconsidering what it means to be literate. The way we consider ourselves to be a literate species is changing, which puts us at a unique turning point in human history. Verbal literacy, or the ability to read and write, is slowly being replaced by visual literacy as a primary tool for human communication. As a culture, we tend to underestimate the creative ferment of our increasingly visual world. The linear, structured pathways of traditional literacy are shifting towards a creative and participatory pursuit of unstructured information that emphasize dimensional thinking. The acceleration …

The Social Progression Of Post -Traumatic Stress Disorder: Post Vietnam And September 11th Attacks, Ellie Mcdonald

Capstone Projects and Master's Theses

The Social Progression of Post-Traumatic Stress Disorder Post-Vietnam and September 11^th Attacks is an examination on the infrastructure of the U.S. Department of Veterans Affairs’and of the Department of Defense’s lack of clarity and misinformation of the challenges and effects of mental illness within military ranks. Post-traumatic stress disorder (PTSD) made the Diagnostic Statistical Manual (DSM) after Vietnam. Since then, PTSD has been reevaluate numerous times, to properly define it. This research is a comparative analysis of the misconceptions of PTSD as experienced by Vietnam veterans and the first responders of the September 11^th tragedy. My research charts …

The Effects Of Meditation On Brain Organization And The Implications For Treating Adhd, Talia Gibson

Honors Projects

Attention-deficit/hyperactivity disorder (ADHD) has recently become increasingly diagnosed for children and adolescents. As of now, the most common treatment method is medication, with the purpose of changing brain organization. Recently, however, there has been increasing interest in the use of mindfulness meditation to treat the symptoms associated with ADHD. In this paper, eleven different studies, which have introduced mindfulness meditation as a treatment method for ADHD, are analyzed. The studies measure the degree to which mindfulness meditation improves common symptoms associated with ADHD. These symptoms include attentional problems, reduced mindful awareness, externalizing and internalizing problems, reduced self-control, impaired social behavior, …

An Exploratory Mixed-Methods Examination Of Empathy And Multiple Intelligences Among Youth Involved In Bullying, Heather Schwartz

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Bullying is a significant issue among school-aged youth, and it is important to examine the underlying mechanisms of these behaviors. Studies have shown that one characteristic found among some children who bully is a lack of empathy. Previous literature examining empathy and bullying has typically relied on the use of self-report data. Few studies have included other ways of evaluating empathy. Self-report data can be limiting, particularly for individuals who possess strengths other than verbal/linguistic. Drawings have been found to reveal insight into children’s emotions and may be more suited to assessing empathy. Studying children’s drawings of bullying, and their …

Exploring The Effect Of Encoding Modality And Rehearsal Strategy On Foreign Language Vocabulary Recall, Danielle R. Bestfelt

Undergraduate Theses

Experience with a foreign language is considered a valuable skill in workplace and school settings alike. However, recent studies in the field of psychology exploring the process of acquiring a second language have limited applicability, especially for adults with English as a first language. This study sought to explore the relation between encoding modality (auditory, visual, or visual and auditory; based on Baddeley’s model of working memory) and rehearsal strategy (active or passive, based on Craik and Lockhart’s Level of Processing approach and Roger’s Self-Reference Effect) in the recall of foreign language vocabulary words. Vocabulary words were the target information …

Reconsolidating: The Effect Of Spatial Context And Expectations, Chris R. Kiley

UNLV Theses, Dissertations, Professional Papers, and Capstones

Consolidation is the process by which memories become stable over time. 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 again 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. The exact boundary conditions for reconsolidation are not yet known. Some studies suggest that reconsolidation is only necessary when new information is presented in a spatial context that is indistinguishable from the …

The Relationship Between Mood And Implicit Learning, Kathleen Larson

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation investigates whether a person’s current mood state influences their ability to learn implicitly. Implicit learning refers to learning about regularities in the environment without having conscious access to the information (e.g., Reber, 1967). According to the affect-as-information hypothesis, a positive mood increases global processing of incoming information and negative mood leads to local processing (e.g., Clore & Storbeck, 2006); however, most previous studies that investigated mood and cognition have focused on more explicit types of learning and decision making, but few have examined implicit processes. Thus, the current experiments examined how varying levels of mood and arousal affect …

An Examination Of Accuracy And Elaborations For Character Traits In A Narrative, Michael Palena

UNLV Theses, Dissertations, Professional Papers, and Capstones

When people read a story, they often form a highly detailed representation known as a situation model. The event-indexing model (Zwaan, Langston, & Graesser, 1995) proposes that situation models are constructed along several indices, one of which is protagonist or character. While much research has been devoted to the study of tracking and forming trait-based models of fictional characters, little attention has been paid to the representation of characters’ external attributes. In Experiment 1, participants read a short story containing various characters and their attributes. Participants were then asked to recall the characters and their attributes, either according to their …

Story Problem Solving, Brian D. Kalina

Creativity and Change Leadership Graduate Student Master's Projects

This project paper will explore and define the relationship between the Creative Problem Solving (CPS) and the timeless concept of storytelling. Since the beginning of time, people have been sharing stories to relate their experiences and their solutions to overcome challenges and obstacles. CPS is a more modern methodology that aids people in their approach and their ability to generate plans and solutions to overcome challenges and obstacles. Therefore, the premise of this project is to seek answers to the questions; (1) How might we look to stories as frameworks for solving our problems? and (2) How might we marry …

Neural Processes Underlying Auditory Context Effects, Breanne Yerkes

UNLV Theses, Dissertations, Professional Papers, and Capstones

Auditory information within our natural environments is disorganized and often ambiguous, leaving our auditory systems with a complex task: organizing sound into coherent objects. The auditory system uses both current and prior information to assist in completing this task. The influences of previous context on current perception have been referred to as context effects. A contrastive context effect results in a current perception that is opposite of what is expected based on the physical stimulus properties presented during an immediate context. A facilitative context effect results in a current perception that is the same as the perception during the immediate …

Video Game Engagement, Gender, And Age: Examining Similarities And Differences In Motivation Between Those Who May Or May Not Play Video Games, Joseph Camarata

Electronic Theses and Dissertations

This research aims to fill a research gap by examining video games to explore whether gender, age, or hours played per week would exert any influence on the information of those who may or may not play video games. Mood Management Theory and Uses and Gratification Theory were used as the theoretical foundation for this study. Four-hundred-three East Tennessee State University students who received the survey via email were asked to voluntarily participate in a survey about their motivations behind playing video games. Results from MANOVA showed that the motivations of male participants on video games were significantly higher than …

Assessing The Relationship Between Change Blindness And The Anchoring Effect, Melissa Schoenlein

Honors Projects

A lack of consideration for all aspects of a question prompts fragmented decision making. These decisions, as they leave out fundamental information, repeatedly then lead to a potentially problematic reaction to the target question or stimuli. The anchoring heuristic propels one to make a decision, usually an estimate, based on a presented “fact”, often ignoring additional background and environmental clues. Reducing the rate of occurrence of the anchoring bias is thought to lead to an increase in holistic decision making. To promote this reduction, the purpose of this research was to affirmexamine the relationship between the susceptibility to change blindness …

The New Theory Of Disuse Predicts Retrieval Enhanced Suggestibility (Res), Victoria Bartek

Seton Hall University Dissertations and Theses (ETDs)

Retrieval enhanced suggestibility (RES) refers to an effect where initial testing of an event leads to better learning of and higher production of misinformation regarding that event. This paper proposes the New Theory of Disuse (Bjork & Bjork, 1992) as a supplement to the retrieval fluency account for RES (Thomas et al., 2010). The amount of interference presented between the misinforming narrative and final test was manipulated in order to investigate how decays in retrieval strength (how easily a memory is recalled) affect misinformation reporting. Results suggested that the learning of interfering information may decrease RES, but that this effect …

Sparking A Dolphin's Curiosity: Individual Differences In Dolphins' Reactions To Surprising And Expectation-Violating Events, Malin Katarina Lilley

Master's Theses

Non-scientific literature consistently describes dolphins as “curious animals,” but there has been little systematic research on curiosity in dolphins. Curiosity in humans and certain non-human animal species, including birds and non-human primates, has been studied by examining individual differences in exploration and reactions to novel stimuli. Additionally, research has explored how human infants and non-human animals react when an event violates their expectations. The present study explored dolphins’ reactions to spontaneously surprising and expectation-violating stimuli. The reactions of dolphins, 15 bottlenose (Tursiops truncatus) and 6 rough-toothed (Steno bredanensis), at Gulf World Marine Park were analyzed in …

Behavioral Finance And Its Impact On Investing, Jordan Fieger

Senior Honors Theses

The field of behavioral finance has seen incredible growth over the past half century as it has explored the effect that cognitive psychological biases can have on investors’ financial decisions. Behavioral finance stands in stark contrast to the efficient market hypothesis, as it attributes market inefficiencies to investors who are not perfectly rational human beings. It offers a solution to the observed 3.5% gap that active equity investors miss out on in the market compared to passive index funds, which it attributes to their emotions and psychological biases. These common human biases can be grouped into five major categories: heuristics, …

Explicit Programming For Icon Rings: Visual-Based Discrimination, Samantha Borowski

Honors Theses

Instructional icons are helpful as basic direction following is the basis for complex skills needed later in life. These instructions should have a good training so that children can get the basic skills and can move on to the complex skills. The goal of the project was to increase the correct responses to instructional icons. Visuals are a good tool for learning because it attaches a picture with the event that is happening or will happen. Children with autism sometimes struggle when they are introduced to a new environment so having a system in place to help make instruction following …
