Information Prioritization: A Comparison Between Utility Maximizers And Probability Matchers, Yusuf Ismaeel
CMC Senior Theses
This thesis examines the differences between probability matchers and utility maximizers in their preferences for information sources in a lab environment. In this paper, we consider the best source of information to be the most connected one. We conducted several linear probability model type regressions along with logit regressions. Furthermore, we also attempted to control and fix any potential misclassifications in classifying the cognitive strategy by using instrumental variables. The results show that utility maximizers will almost always choose the most informed node. Probability matchers, on the other hand, do not exhibit such a behavior as the probability matching strategy …
Corticostriatal Pathway Inactivation And Connections To Associative Learning With Nicotine Stimulus In Rats,

Corticostriatal Pathway Inactivation And Connections To Associative Learning With Nicotine Stimulus In Rats, Anna Kalinowski
Honors Theses and Capstones
The main concern of this study is looking into the neural mechanisms of associative learning with a nicotine stimulus. The goal of this study was to find out if inactivating the corticostriatal pathway through DREADDs (Designer Receptors Exclusively Activated by Designer Drugs) inhibited goal-tracking behavior in rats. In this experiment, rats underwent two surgeries. One was to inject DREADDs into the infralimbic cortex and the other in the dorsomedial caudate-putamen (dmCPu). Rats were initially trained on levers through water deprivation. Once they reached the criterion, they moved on to the self-administration phase. After the rats were trained in self-administration sessions …

Frontal Alpha Wave Asymmetry In Regard To Affect, Monica Leigh Sewell
All Master's Theses
This study examines frontal alpha brain wave asymmetry (FAA) in relation to emotion processing. Previous research has shown that differences between left versus right FAA could exhibit a neurological marker for emotional intelligence (EI), mental health, and stress. Behavioral data were collected using Profile of Emotional Competence Questionnaire, Perceived Stress Questionnaire, Patient Health Questionnaire-9, and the Generalized Anxiety Disorder-7. This was followed by a series of resting EEG recordings. This study hypothesizes that participants who are mentally healthy, have higher EI scores and lower stress will display greater left FAA. The hypothesis is partially supported; participants with depression had greater …

The Role Of Acetylcholine In Attention And Lapses In Attention In Rats Using The Mode And Deviation From Mode Of Reaction Time Latency, Scott Lee Mitchell
Electronic Theses and Dissertations
Attention Deficit-Hyperactivity Disorder (ADHD) is currently the neurodevelopmental disorder most commonly diagnosed in children in the United States, and one of the defining characteristics of ADHD is inattention. Inattention is marked by increased lapses in attention, and when assessed clinically, it has been highly correlated with reaction-time variability (RTV). Evidence from the human/clinical literature has shown an inherently higher RTV to be the primary quantitative indicator of an ADHD diagnosis. Reaction-time distributions are characterized by an asymmetrical rightward skew, and because of the prevalence of this presentation, it has been theorized that the distribution peak and skew represent separate phenomena, …

Post-Bariatric Surgery Patients Fail To Exercise Consistently: Exploring The Potential Role Of Self-Compassion, Naomi Teeter
EWU Masters Thesis Collection
Many bariatric weight loss surgery patients do not exercise after surgery. One potential reason this population may not exercise is due to body image shame and low self-compassion, which can contribute to lower appreciation for one’s body. Adult participants from an international bariatric population sample (N = 805) and an Eastern Washington University undergraduate student sample (N = 104) completed a one-time online questionnaire that included measures of self-compassion, physical activity frequency, body appreciation, and body image shame. In the bariatric sample, self-compassion was indirectly associated with exercise frequency via body appreciation and body image shame. Additionally, at the highest …

Visual Perception And Action In Reaching During Upper Limb Obstacle Avoidance, Nondon Chakraborty
Theses and Dissertations (Comprehensive)
During everyday activities, people reach to specific objects with their hands and avoid obstacles. For people to move successfully through an obstacle gap, it is necessary to be able to accurately perceive the actions that the surroundings afford and adjust hand movements accordingly. Reaching behaviours, including planning (perception) and execution (action), depend on visual information. This study aimed to understand and detect the differences between perceptual judgment and actual performance of both hands during a reaching task at the time of obstacle avoidance by using a hand-scaled approach. Participants were young adults (male (n=7) and female (n=10) aged 18 to …

Decipher The Effect Of Gamification In Harnessing Boredom And Improving Performance, Zhuoyi Zhao
Theses and Dissertations (Comprehensive)
My thesis investigates the effectiveness of gamification in harnessing boredom and improving performance in a repetitive work process. In video games, “loot” rewards are unpredictable, intermittent gains used to motivate players to repeat boring actions. In a 2 X 2 experiment, I examine how loot rewards in point form may impact 1) disengagement, which is an immediate outcome of boredom, and 2) performance in settings where the points have and do not have cash value, respectively. More specifically, I manipulate the level of point reward unpredictability (fixed versus loot) and whether point rewards have cash value (absent versus present).

Pharmacokinetics And Reward-Related Behaviors Of Ethanol In Male And Female Japanese Quail (Coturnix Japonica), Shannon Eaton
Theses and Dissertations--Psychology
Ethanol is one of the most widely used and abused drugs. Problem use is associated with many different health problems and the economic burden is in the billions of dollars. Additionally, many people have difficulty controlling their ethanol consumption and about 5% of adults end up with an alcohol use disorder (AUD). Many people with an AUD often find themselves in a cycle of binge, remission, and relapse.
Following ethanol consumption ethanol enters the bloodstream from the small intestine where it gets distributed to peripheral tissues. Ethanol in the bloodstream is cleared from the system by the liver. The primary …

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 Of Barriers To Treatments, And The Attitudes And Beliefs Toward Medication Assisted Treatment (Mat) On The Readiness To Change Within Young Adults Engaging In Regular Alcohol And Opioid Use., Kylie Thorwardson, Ryan Carpenter, Miriam Mead
Undergraduate Research Symposium
People who use substances vary in terms of the problems they experience and the degree to which they feel change is needed. Among those who are interested in making changes, many have qualms and questions about doing so, despite the potential positive benefits of reducing use. Young adults who use substances are especially unlikely to receive substance-focused treatment. It is unclear to what extent this is due to limited access to treatment, a lack of desire to change, beliefs that existing treatments are unlikely to be beneficial, or a combination of factors. This study will examine the associations of perceived …
Influence Of Increased Options On Performance Generalization Across Two Variations Of The Monty Hall Dilemma,

Influence Of Increased Options On Performance Generalization Across Two Variations Of The Monty Hall Dilemma, Robert A. Southern
College of Graduate Studies: Theses & Dissertations
The Monty Hall dilemma (MHD) is a probability puzzle at which humans consistently fail to adopt the optimal winning strategy. The participant chooses between three identical doors, behind one of which is a valuable prize. After the participant makes their initial decision, the host reveals that there is nothing behind one of the two remaining doors, then asks the participant if they would like to stay with their originally selected door or switch to the remaining unopened door. The optimal choice is to switch to the previously unchosen door, which increases the probability of winning from 33% to 67%. Despite …

Understanding Racial Experiences And The Influence Of Family On Stress And Familism Attitudes, Jaqueline Miranda
College of Graduate Studies: Theses & Dissertations
Sixty-five percent of undergraduates reported family as their most important in-group and 79% reported family as being in their top three in-groups (McConnell, 2019). Familial bonds are vital for racial ethnic minorities because of their unique experiences as minorities such as experienced racism, acculturative stress, and other forms of adversity. The current study examined the effects of a racially-based stress induction and imaginal exercise on state stress levels and familial attitudes, and the relationship between racial-ethnic socialization and racial battle fatigue including kinship social support as a moderator. The study used an experimental design, manipulating stress induction through a script …

Entitled To Be Served: Does Self-Checkout Make Customers Feel Less Rewarded?, Farhana Nusrat, Yanliu Huang
AMTP Proceedings 2021
The adoption of self-service technologies (SST) has been rising over the last few years, and among different SSTs, self-checkout systems are one of the most popular options. In this study, we examine how self-checkout service impacts customers’ shopping outcomes compared to regular checkout service. We propose that self-checkout (vs. regular checkout) systems, would make customers feel less rewarded and less satisfied with their purchases. We conducted four studies to test our hypotheses and showed that self-checkout (vs. regular checkout) service makes customers feel less rewarded, less satisfied with their shopping outcomes, and less likely to return to the store. We …
Response Interruption And Redirection (Rird) As A Treatment For Vocal Stereotypy In Children Who Are Dually Diagnosed With Autism And Down Syndrome,

Response Interruption And Redirection (Rird) As A Treatment For Vocal Stereotypy In Children Who Are Dually Diagnosed With Autism And Down Syndrome, Stacy Taylor
Theses and Dissertations
Individuals who are dually diagnosed with Down Syndrome (DS) and autism spectrum disorders (ASD) frequently engage in vocal stereotypy that can interfere with learning, impede socially appropriate behavior, and disrupt others. Response interruption and redirection (RIRD) is an intervention that blocks and redirects stereotypy to reduce behavior. Studies on RIRD, while varied in their overall approach, have overwhelmingly been shown to be effective in clinical settings for children with ASD. There are few studies that have evaluated this procedure in more natural settings and with other diagnoses. Given that ASD is prevalent in those with DS and that stereotypy is …

Online Training To Improve Job Coaches’ Support Of Minimally Verbal And Nonverbal Adults With Autism Spectrum Disorder, Erin Brooker Lozott
Theses and Dissertations
Although a sizeable percentage of individuals with autism spectrum disorder (ASD) are minimally verbal or nonverbal, there is limited research on how to best support these individuals in employment settings. Job coaches working with this population should receive specialized training in evidence-based practices (EBP) for ASD to ensure optimal outcomes. This study describes the development, implementation, and evaluation of an online training program for job coaches focused on a behavior skills training approach supporting the use of augmentative and alternative communication. Twenty-two job coaches completed the study. Pre- and posttraining measures were used to evaluate knowledge, self-efficacy, and belief systems …
Effects Of Nonexamples On Concept Formation,

West Virginia University
Effects Of Nonexamples On Concept Formation, Catherine Louise Williams
Graduate Theses, Dissertations, and Problem Reports (ETD)
Concept formation is affected by the examples and nonexamples provided during training, but the degree to which examples and nonexamples should differ is unknown. Two experiments compared concept formation when different kinds of nonexamples were used during training. Both experiments included a within-subject comparison of concept formation following three training conditions: a) nonexamples that were more similar to the examples, b) nonexamples that are less similar to the examples, and c) no nonexamples. Arbitrary concepts were trained in Experiment 1 and concepts akin to those that could be taught in a classroom were trained in Experiment 2. Before and after …

Effects Of Acute And Chronic Nicotine Administration On Choice Of Probabilistic Outcomes, Katya A. Nolder
Graduate Theses, Dissertations, and Problem Reports (ETD)
Risky choice can be operationally defined as the choice for a larger, uncertain reinforcer over a smaller, certain reinforcer. Research suggests smokers engage in more risky or maladaptive decisions when compared to nonsmokers. The relation between nicotine and risky choice could benefit from further investigation, since nicotine is the active substance of tobacco products that maintains tobacco addiction. Acute nicotine administration has shown to alter risky choice; however, since the everyday smoker uses nicotine repeatedly, more research on chronic administration is warranted and would allow for assessment of tolerance or sensitization of these effects. The present study investigated effects of …
Discriminative Stimulus Effects Of Cannabidiol Oil In Rats,

Discriminative Stimulus Effects Of Cannabidiol Oil In Rats, Rebecca L. Chalme
Graduate Theses, Dissertations, and Problem Reports (ETD)
Cannabidiol (CBD) is one of the major centrally active phytocannabinoid components of cannabis, and has been approved by the FDA only for the treatment of two rare seizure disorders. However, CBD has been touted as a potential treatment for anxiety in place of more traditional treatments like benzodiazepines. Although there is some evidence of anxiolytic effects of CBD, its suitability as a substitute for benzodiazepines is unknown. This experiment was designed to assess to what extent CBD shares interoceptive discriminative-stimulus properties with the anxiolytic chlordiazepoxide (CDP), a benzodiazepine. In the present experiment, a range of doses (0-333.3 mg/kg) of over-the-counter …
An Analysis Of Coordinated Responding,

An Analysis Of Coordinated Responding, Brian Katz
Graduate Theses, Dissertations, and Problem Reports (ETD)
Experimental analyses of coordinated responding (i.e., cooperation) have been derived from a procedure described by Skinner (1962) in which reinforcers were delivered to a pair of subjects (a dyad) if both responded within a short interval, thus satisfying a mutual-reinforcement contingency. Although it has been suggested that this contingency enhances rates of temporally coordinated responding, limitations of past experiments have raised questions concerning this conclusion. The present experiments assessed three of those limitations by holding the schedule of reinforcement (Experiment 1: fixed-ratio 1; Experiment 2; variable-interval 20 s) constant (1) across phases and (2) between dyad members, and (3) varying …
Effects Of Blended Integrity Failures On Reinforcement-Based Interventuions,

Effects Of Blended Integrity Failures On Reinforcement-Based Interventuions, Stephanie Hope Jones
Graduate Theses, Dissertations, and Problem Reports (ETD)
Reinforcement-based interventions reduce problematic behavior when implemented as designed. However, the effectiveness of these interventions may decrease when deviations from treatment protocols (i.e., treatment-integrity errors) occur. Treatment-integrity errors differentially impact reinforcement-based interventions based on multiple factors, including how frequently errors occur and the intervention type. Even nominally acceptable integrity values (e.g., 80%) may be detrimental depending on the intervention. To evaluate this possibility and directly compare the effectiveness of multiple reinforcement-based interventions, we conducted two within-subject evaluations using laboratory arrangements. For both experiments, we recruited four undergraduate students to participate in a computer task that involved clicking on moving circles …
