Investigation Of Videogame Flow: Effects Of Expertise And Challenge, Jolie G. Gascon

Doctoral Dissertations and Master's Theses

The number of participants in this expertise and videogame flow test totaled 80 from multiple target locations. Participants engaged in various levels of the videogame Super Mario Bros. Twenty experts and twenty novices experienced the easier level of World 1-2 while the other twenty experts and novices were exposed to the more difficult level World 6-1. After gameplay, participants completed a modified survey measuring flow. This survey, along with overall percentage game score, was analyzed. A significant interaction was found between game level (challenge level) and skill levels in perceived immersion, with significant main effects for expertise in perceived skill, …

The Effects Of Acute Psychosocial Stress On Cognitive Performance, Anne I.S. Gray

Doctoral Dissertations and Master's Theses

The purpose of this study was to examine the effects of acute psychosocial stress on cognitive performance. Psychosocial stress evolves from the perceived presence of a social evaluative threat and results in the activation of the home hypothalamic-pituitary-adrenal axis. As part of this reaction the stress hormone cortisol is secreted into the blood stream, ultimately crossing the blood-brain barrier, where it can have profound effects on various aspects of cognition. A review of the literature reveals that that attention, working memory, spatial judgment and cognitive processing efficiency are particularly susceptible to stress induced changes in performance level. A test battery …

The Effects Of Sensor Performance As Modeled By Signal Detection Theory On The Performance Of Reinforcement Learning In A Target Acquisition Task, Nate Quirion

Doctoral Dissertations and Master's Theses

Unmanned Aerial Systems (UASs) today are fulfilling more roles than ever before. There is a general push to have these systems feature more advanced autonomous capabilities in the near future. To achieve autonomous behavior requires some unique approaches to control and decision making. More advanced versions of these approaches are able to adapt their own behavior and examine their past experiences to increase their future mission performance. To achieve adaptive behavior and decision making capabilities this study used Reinforcement Learning algorithms. In this research the effects of sensor performance, as modeled through Signal Detection Theory (SDT), on the ability of …

Are All Types Of Expertise Created Equal? Car Experts Use Different Spatial Frequency Scales For Subordinate Categorization Of Cars And Faces, Assaf Harel, Shlomo Bentin

Psychology Faculty Publications

A much-debated question in object recognition is whether expertise for faces and expertise for non-face objects utilize common perceptual information. We investigated this issue by assessing the diagnostic information required for different types of expertise. Specifically, we asked whether face categorization and expert car categorization at the subordinate level relies on the same spatial frequency (SF) scales. Fifteen car experts and fifteen novices performed a category verification task with spatially filtered images of faces, cars, and airplanes. Images were categorized based on their basic (e.g. ‘‘car’’) and subordinate level (e.g. ‘‘Japanese car’’) identity. The effect of expertise was not evident …

The Influence Of Mindful Attention On Value Claiming In Distributive Negotiations: Evidence From Four Laboratory Experiments, Jochen Reb, Jayanth Narayanan

Research Collection Lee Kong Chian School Of Business

We examined the effect of mindful attention on negotiation outcomes in distributive negotiations across four experiments. In Studies 1 and 2, participants who performed a short mindful attention exercise prior to the negotiation claimed a larger share of the bargaining zone than the control condition participants they negotiated with. Study 3 replicated this finding using a different manipulation of mindful attention. Study 4 again replicated this result and also found that mindful negotiators were more satisfied with both the outcome and the process of the negotiation. We discuss theoretical and practical implications, limitations, and future directions.

Contain Yourself, Gianina Gelatro

SURGE

I can’t say I’ve ever been known as the most organized person in the world. Likely due to clothing littered around my bed and papers sprawled across my desk, my living space is usually greeted with the phrase, “Well, it definitely looks lived-in.” Feeling fed-up with my clutter and inspired by a bout of Spring Fever, I took my first trip to the The Container Store this past weekend. I was overwhelmed and excited by the immense amount of gadgets and boxes that existed to compartmentalize any and every aspect of my life. They really have it all from jewelry …

Does Child Sponsorship Have A Positive Impact On The Quality Of Life And Social Behavior Of Sponsored Children? Evidence From Indonesia, Mario Carrillo

Master's Theses

Relaxing an internal constraint of an individual at early stages of life is an approach that complements traditional policy interventions aimed to alleviate poverty. The Compassion International child sponsorship program focuses their work on the emotional, social, and spiritual development of sponsored children. This study investigates the impacts of child sponsorship on the quality of life and social behavior of sponsored children using age-eligibility as an instrument for sponsorship, a time preference experiment and a trust game. The study looks specifically at self-esteem, optimism, social trust, educational outcomes, patience and reciprocity of 286 sponsored children and 234 non-sponsored children between …

The Influence Of Spatial Distance Priming On Test Anxiety And Judgments, Eric R Raap

Masters Theses & Specialist Projects

This paper examined the effects of distance priming on test anxiety and judgment. Research suggests that individuals’ perceived distance can impact their affect and judgments, which sheds light on the principle of “distance equals safety” (Williams & Bargh, 2008). Taking an exam invokes both cognitive and emotional anxiety, such as worry, panic, and tension. It is hypothesized that the distance priming may reduce test anxiety—particularly, the emotionality aspect—as well as perceived test difficulty. The results showed that, counter to the hypotheses, there was no significant difference among the three priming groups in their emotional test anxiety or perceived test difficulty. …

Self-Regulation And Physical Activity In Wku Employees, Scott Perkins

Masters Theses & Specialist Projects

Many Americans do not engage in the recommended amount of physical activity, and thus do not receive the potential physical and mental health benefits from physical activity. Stage of change is a model that categorizes individuals into one of five stages based on behavior and intentions for future behavior. This model is useful for promoting physical activity because it allows for tailoring of interventions to individuals with different physical activity levels and readiness for change. The main purpose of this research was to test if more adaptive scores for Essential Self-Regulation Model (ESRM) constructs are found for persons in higher …

The Effects Of Gender And Implicit Theories On Science Achievement And Interest In Elementary-Aged Students, Savannah Benningfield

Participants in the current study consisted of a total of 1910 students from six elementary schools from one south-central Kentucky district that participate in Project GEMS (Gifted Education in Math and Science). Data were analyzed by means of analysis of variance and Pearson correlations. Younger students evidenced lower scores on …

Evaluation Of A Short-Form Of The Berg Card Sorting Test, Christopher J. Fox, Shane T. Mueller, Hilary M. Gray, Jacob Raber, Brian J. Piper

Psychology Faculty Publications and Presentations

The Psychology Experimental Building Language http://pebl.sourceforge.net/Berg Card Sorting Test is an open-source neurobehavioral test. Participants (N = 207, ages 6 to 74) completed the Berg Card Sorting Test. Performance on the first 64 trials were isolated and compared to that on the full-length (128 trials) test. Strong correlations between the short and long forms (total errors: r = .87, perseverative response: r = .83, perseverative errors r = .77, categories completed r = .86) support the Berg Card Sorting Test-64 as an abbreviated alternative for the full-length executive function test.

Attention And Criminal Charge, Profile And Description: The Effect On Prospective Person Memory, Lindsey Nicole Sweeney

Graduate Theses and Dissertations

Prospective person memory is the ability to recognize and react to a missing or wanted individual that one has been asked to be on the lookout for in the future. Prospective person memory relies on several processes including face recognition, event-based prospective memory, and attention. Only recently has research on the role of visual attention on prospective person memory been examined. In this dissertation, the gap between prospective person memory and attention is addressed. Although research on prospective person memory is steadily increasing, the research in this area is still in its infancy and the exact memory mechanisms that affect …

Witnessing Reconciliation Reduces Arousal Of Bystanders In A Baboon Group (Papio Hamadryas Hamadryas), Peter G. Judge, Katherine A. Bachmann

Faculty Journal Articles

Reconciliation is the occurrence of friendly behaviour between opponents shortly after an aggressive conflict. In primate groups, reconciliation reduces aggression and post-conflict arousal. Aggression within a group can also increase arousal of bystanders (e.g. increase bystanders’ rates of self-directed behaviour). Since reconciliation reduces aggression between opponents, we tested whether it also reduces self-directed behaviour in bystanders. Following aggression in a captive group of hamadryas baboons, one observer conducted a focal sample on one of the combatants to document reconciliation and a second observer simultaneously conducted a focal sample on a randomly selected bystander. Matched control observations were then collected on …

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 …

A Conceptual Model Of Exploration Wayfinding: An Integrated Theoretical Framework And Computational Methodology, Matthew Lee Tenney

Graduate Theses and Dissertations

This thesis is an attempt to integrate contending cognitive approaches to modeling wayfinding behavior. The primary goal is to create a plausible model for exploration tasks within indoor environments. This conceptual model can be extended for practical applications in the design, planning, and Social sciences. Using empirical evidence a cognitive schema is designed that accounts for perceptual and behavioral preferences in pedestrian navigation. Using this created schema, as a guiding framework, the use of network analysis and space syntax act as a computational methods to simulate human exploration wayfinding in unfamiliar indoor environments. The conceptual model provided is then implemented …

Concurrent Neurological And Behavioral Assessment Of Number Line Estimation Performance In Children And Adults, Joseph Michael Baker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Understanding the brain’s response to common math-learning activities may help improve math education. For example, by imaging the brains of typically developing children and adults throughout a number line estimation task, it is possible to establish a baseline of what “typical” brains do in such situations. Thus, comparisons may be made to determine the degree to which brain functioning differs between typical and atypical math learners. Moreover, by identifying methods that may increase the brain’s response to real-world math activities, it may be possible to improve the math learning process for typical and atypical learners alike.

Brain imaging devices such …

The Effects Of Selected Drugs On The Memory Recall Of Sleep Deprived Mice, Jenn Pauldurai

Capstone Research Projects

Humans often make use of the neurotransmission altering effects of drugs such as caffeine, ephedrine, and ethanol. These drugs induce changes in memory and learning ability, specifically when used for sleep deprivation. English white mice (Mus musculus) have been shown to exhibit similar cognitive changes when administered drugs while sleep deprived. A sample of 20 mice was divided into three experimental groups (each group receiving a different drug) and one control group. Maze-testing demonstrated that mice performance decreased with sleep deprivation (Treatment-1) but all groups returned to baseline performance when injected (IP) with selected drugs (Treatment-2), regardless of …

Getting A Grip On Memory: Unilateral Hand Clenching Alters Episodic Recall, Ruth E. Propper, Sean E. Mcgraw, Tad T. Brunyé

Department of Psychology Faculty Scholarship and Creative Works

Unilateral hand clenching increases neuronal activity in the frontal lobe of the contralateral hemisphere. Such hand clenching is also associated with increased experiencing a given hemisphere’s “mode of processing.” Together, these findings suggest that unilateral hand clenching can be used to test hypotheses concerning the specializations of the cerebral hemispheres during memory encoding and retrieval. We investigated this possibility by testing the effects of a unilateral hand clenching on episodic memory. The hemispheric Encoding/Retrieval Asymmetry (HERA) model proposes left prefrontal regions are associated with encoding, and right prefrontal regions with retrieval, of episodic memories. It was hypothesized that right-hand clenching …

Analysis Of Gender Differences In Self-Statements And Mood Disorders, Robert Devore

McNair Scholars Research Journal

Over 25% of adult Americans suffer from a mental disorder each year, with depression and anxiety being some of the most commonly reported issues. Researchers estimate that between 10% and 50% of adult Americans will suffer from a depressive episode at some point in their life, and cognitive theorists argue that mental states, including disorders, are generated and maintained by personal, subjective beliefs, and that events can only be appropriately labeled by the individual experiencing them. Thus, cognitive theorists suggest a strong link between self-talk (ST) and behavior and note that the automatic use of ST is associated with disordered …
