The Midsession Reversal Task With Pigeons: Effects Of A Brief Delay Between Choice And Reinforcement, Megan Ashley Halloran

Theses and Dissertations--Psychology

During a midsession reversal task, the session begins with a simple simultaneous discrimination in which one stimulus (S1) is correct and the alternate stimulus (S2) is incorrect (S1+/S2-). At the halfway point, the discrimination reverses and S2 becomes the correct choice (S2+/S1-). When choosing optimally, a pigeon should choose S1 until the first trial in which it is not reinforced and then shift to S2 (win-stay/lose-shift). With this task pigeons have been shown to respond suboptimally by anticipating the reversal (anticipatory errors) and continuing to choose S1 after the reversal (perseverative errors). This suboptimal behavior may result from a pigeon’s …

The Stained Glass Of Knowledge: On Understanding Novice Mental Models Of Computing, Briana Christina Bettin

Dissertations, Master's Theses and Master's Reports

Learning to program can be a novel experience. The rigidity of programming can be at odds with beginning programmer's existing perceptions, and the concepts can feel entirely unfamiliar. These observations motivated this research, which explores two major questions: What factors influence how novices learn programming? and How can analogy by more appropriately leveraged in programming education?

This dissertation investigates the factors influencing novice programming through multiple methods. The CS1 classroom is observed as a "whole system", with consideration to the factors present in it that can influence the learning process. Learning's cognitive processes are elaborated to ground exploration into specifically …

Examining Environmental Use By Captive Lemur Catta And Varecia Rubra, Rhiannon Belcher

All Master's Theses

There are over 100 named species of lemurs, of which 94% are considered threatened with extinction by the International Union for the Conservation of Nature (IUCN). They live in increasingly fragmented forests. To understand how best to protect them in their natural habitats, we can observe how they manipulate the environment and how they use objects, both natural and humanmade, around them. Understanding their behavior is a critical component of conservation, and observing behavior in a captive setting allows us to study lemur-environment relationships without disrupting what little habitat is left in Madagascar. In this study I investigated whether the …

Fast Decision-Making Under Time And Resource Constraints, Kyle Gabriel Lassak

Graduate Theses, Dissertations, and Problem Reports (ETD)

Practical decision makers are inherently limited by computational and memory resources as well as the time available in which to make decisions. To cope with these limitations, humans actively seek methods which limit their resource demands by exploiting structure within the environment and exploiting a coupling between their sensing and actuation to form heuristics for fast decision-making. To date, such behavior has not been replicated in artificial agents. This research explores how heuristics may be incorporated into the decision-making process to quickly make high-quality decisions through the analysis of a prominent case study: the outfielder problem. In the outfielder problem, …

Does Being Unaware Predict Being Unskilled? Analyzing The Predictive Ability Of The Metacognition Awareness Inventory, Daniel A. Scheibe

EWU Masters Thesis Collection

Students’ perceptions of how well they know information ultimately impact the study choices they make. The more accurate these perceptions are, the more prepared students are to be academically successful. Thus, the current study aimed to find an efficient way to quickly identify students who struggle with this self-assessment, and ultimately classroom performance, using a tool designed to assess metacognitive ability. Participants first completed a metacognition scale designed to assess learning strategies – the Metacognitive Awareness Inventory (MAI). Next, the participants were administered a 29-minute lecture followed by a brief exam at the end of the lecture. There were three …

The Effects Of Positive Emotions On Eyewitness Memory, Brandy R. Hutton

EWU Masters Thesis Collection

The purpose of this study was to explore the effects of positive emotions on eyewitness memory. Though little research has been done investigating this question, it has serious implications within the criminal justice system, towards our understanding of emotions, and in creating a fuller comprehension of how memory works. The current study chose two distinct positive emotions and participants were randomly assigned to one of three emotion inductions (joy, gratitude, or neutral). Participants then watched a computer video of a minor crime and responded to questionnaires testing them on their recall accuracy of central and peripheral details of that crime. …

The Longitudinal Parallel Process Analysis Of Biomarkers Of Oxidative Stress, Symptom Clusters, And Cognitive Function In Children With Leukemia, Mary C Hooke, Daniel Hatch, Marilyn J Hockenberry, Susan Whitman, Ida Moore, David Montgomery, Kari Marano, Pauline Mitby, Michael E Scheurer, Olga Taylor, Wei Pan

Faculty, Staff and Students Publications

Background: During treatment for acute lymphoblastic leukemia (ALL), children report co-occurring symptoms of fatigue, sleep disturbance, pain, nausea, and depression as a symptom cluster. Central nervous system–directed ALL therapies also put children at risk for cognitive impairments. Cancer therapies can cause an increase in oxidative stress, which may contribute to treatment-related symptoms. This study examined the longitudinal relationships between biomarkers of oxidative stress in the cerebrospinal fluid, the Childhood Cancer Symptom Cluster–Leukemia (CCSC-L), and cognition, in children over the first year of ALL treatment. Methods: Glutathione (GSH) biomarkers of oxidative stress were measured in cerebrospinal fluid collected during treatment lumbar …

Infants’ Relationship With Drop-Offs And Water Environments, Carolina Burnay Rodrigues De Morais

Theses: Doctorates and Masters

Underpinned by the ecological approach to perceptual-motor development, this Thesis aims to contribute to the understanding of the organization of infants’ behaviour during encounters with drop-offs and water environments. Previous studies have linked locomotor experience to infants’ avoidance of falling from heights. Using the Real Cliff / Water Cliff apparatus, Burnay and Cordovil (2016) confirmed the effect of locomotor experience on crawlers’ avoidance of drop-offs and linked locomotor experience to infants’ avoidance of falling into the water for the first time. However, the effect of other specific locomotor experiences on infants’ approach to aquatic environments has not been addressed. This …

Do Faces Facilitate Or Distract Children From Attending To Threats?, Sarah A. Skidmore

Senior Honors Projects, 2010-2019

Threatening stimuli may produce an attentional bias in humans, capturing and holding attention to a greater extent than other types of stimuli. Humans rely on others to alert their attention to threats in their environment, and social stimuli, such as faces, have privileged processing compared to nonsocial stimuli. We wanted to explore whether task-irrelevant fearful or neutral faces facilitate, distract, or have no effect on the detection of threatening or neutral images (spiders and frogs, respectively). Three- to-five-year-old children (N=37) completed a visual search task in which they searched for threatening or neutral animals. Consistent with previous literature, we found …

Spatial Organization In Self-Initiated Visual Working Memory, Hagit Magen, Tatiana Aloi Emmanouil

Publications and Research

Ample research in visual working memory (VWM) has demonstrated that the memorized items are maintained in integrated spatial configurations, even when the spatial context is task irrelevant. These insights were obtained in studies in which participants were provided with the information they memorized. However, the encoding of provided information is only one aspect of memory. In everyday life, individuals often construct their own memory representations, an aspect of memory we have previously termed self-initiated (SI) working memory. In this study, we employed a SI VWM task in which participants selected the visual targets they memorized. The spatial locations of the …

Visual Modulation Of Resting State Α Oscillations, Kelly Webster, Tony Ro

Publications and Research

Once thought to simply reflect passive cortical idling, recent studies have demonstrated that α oscillations play a causal role in cognition and perception. However, whether and how cognitive or sensory processes modulate various components of the α rhythm is poorly understood. Sensory input and resting states were manipulated in human subjects while electroencephalography (EEG) activity was recorded in three conditions: eyes-open fixating on a visual stimulus, eyes-open without visual input (darkness), and eyes-closed without visual input (darkness). We show that α power and peak frequency increase when visual input is reduced compared to the eyes open, fixating condition. These results …

You’Re The Boss: The Stereotype Content Model As A Predictive Behavioral Tool In Résumé Evaluation Processes, Caylin M. Faria

Honors Program Theses and Projects

Extensive literature has confirmed that hiring discrimination is a persistent problem; less research has focused on the social cognitive mechanisms of prejudicial hiring and its effects on résumé evaluations. The present study evaluated how stereotyped evaluations of minority candidates could be predicted with the Stereotype Content Model (SCM) dimensions of warmth and competence. No published research has demonstrated how SCM group ratings may predict evaluations of individuals and their qualifications for employment. Participants evaluated two résumés for each of five listed job positions and completed a survey packet. One résumé in each pair suggested membership in a minority group: Muslim, …

Autism Spectrum Disorders And Positive Familial Effects, Genevieve Weaver

Senior Honors Theses

Autism Spectrum Disorders (ASD) have been found to significantly impact familial structures and outcomes in various studies. The majority of the impact, however, has been primarily negative; effects like increased stress, marital discontentment, and stigmatization are commonly expressed by families. In this study data from a questionnaire, interview, and picture presentations were analyzed and triangulated to identify the positive familial effects of having a child or sibling with ASD. Parents and siblings shared that having a child or sibling with ASD has bettered their life through learning to enjoy the identity of the individual with ASD, through personal growth, and …

Influences Of Reasoning And Achievement Motivation On Complex Problem Solving In A New Microworld Operationalization, Stephan Bartholdy, Ulrike Kipman

Journal of Global Education and Research

Complex Problem Solving (CPS) can be defined as those psychological processes that enable a person to achieve goals under complex conditions, which are characterized by their complexity, connectivity, dynamics, lack of transparency, and polytely. Although many hypothesized influences have previously been tested concerning their relevance for the process of solving complex problems (e.g., general intelligence), results were often found to be rather heterogeneous. As this was found to be partially caused by fundamental differences between measurements of CPS, a new operationalization was used in the present study: Following the Microworld approach, CPS was assessed in the simulation game Cities: Skylines …

Components Of Mindfulness Training: Impacts On Attention And Affect, Maximilian Fey

Graduate Theses and Dissertations

The literature on mindfulness supports a distinction between two components of non-judgmental acceptance and directed attention. The present research analyzed whether there are distinct differences in attentional capabilities or affect between mindfulness inductions which differed in either including only directed attention or directed attention and non-judgmental acceptance. I hypothesized that the acceptance component of mindfulness would increase participants sustained attentional capabilities relative to a control condition; furthermore, I hypothesized that the non-judgmental acceptance component of mindfulness would lead to significant increases in positive affect and decreases in negative affect relative to control. Lastly, I hypothesized that an individual difference measure …

Changes In Cortical Processing Following Unilateral Visual Cortex Deafferentation, Matthew Gannon

Graduate Theses and Dissertations

After the loss of inputs, cells in visual cortex adapt and begin representing space beyond their classical receptive fields. This ability for functional reorganization is a phenomenon known as neuroplasticity. Homonymous hemianopia is a unique case of this scenario that results from hemispheric deafferentation, or when all visual inputs in to one hemisphere of the brain are lost. This condition occurs due to unilateral damage of the post-chiasmatic geniculo-striate pathway, the network that carries visual information from one side of visual space to the visual cortex for processing. Damage to this pathway causes perceptual blindness in the side of space …

Visual Illusion Susceptibility In Dogs Using The Ebbinghaus-Titchener Illusion In A Spontaneous Choice Task, Nicolette Becker

Theses and Dissertations

In recent years, dogs have been a popular test subject when studying visual illusion susceptibility. Multiple studies have investigated whether animals perceive illusions as humans do, but few studies have evaluated dogs’ perception of illusory stimuli. In this thesis, we studied if dogs are visually susceptible to the Ebbinghaus-Titchener illusion when presented in a spontaneous choice task. Subjects were presented two visual images on a board, which had bologna pieces embedded in the stimuli. In control trials, two different sized bologna pieces were placed in the center of the images. In these control conditions, dogs were expected to choose the …

Ethics And Care: For Animals, Not Just Mammals, Jennifer A. Mather

Speciesism and Breed Discrimination Collection

In the last few decades, we have made great strides in recognizing ethics and providing care for animals, but the focus has been mainly on mammals. This stems from a bias of attention not only in research but predominantly in non-scientists’ attention (to ‘popular’ animals), resulting partly from discussion about and depiction of animals in publications addressed to the public. This is somewhat due to political pressure, and can result in uneven conservation efforts and biases in targets for welfare concerns. As a result, there has been a huge backlash again, with concerns about pain sensitivity and welfare in fish, …
