Exploring The Intersectionality Between Homelessness And Addiction: A Review, Antonia Miranda

Honors Projects

The homelessness crisis and drug epidemic have been, and continue to, ravage the nation in a manner that is both detrimental to society and humanity. The correlation between substance abuse and homelessness is enormous, though not necessarily causal. The conditions of being homeless coupled with the prevalence of mental illness drastically increases the susceptibility to substance abuse and addiction. On the other hand, addiction and substance abuse can contribute to someone entering homelessness. The intersectionality between the two is frequently ignored, yet critical to address. Informed by research regarding both conditions, the implications for public policy and reform are huge. …

The Influence Of Prediction Error Strength On Reconsolidation, Kevin D. Mohawk

UNLV Theses, Dissertations, Professional Papers, and Capstones

It has been well established that consolidated memories can be reactivated and enter a labile state where they are once again vulnerable to modification. Reactivated memories, therefore, need to be restabilized or reconsolidated. Prediction error (PE) is one of the most common ways of reactivating consolidated memories, yet no studies have examined how varying the strength of PE influences reconsolidation. The present study aimed to determine if the strength of PE is an important factor for triggering reconsolidation and if so, how PE strength influences the reconsolidation process, whether through strengthening or weakening the memory. To vary PE strength, participants …

Comparing Comics And Illustrated Texts In Multimedia Learning, Jackson S. Pelzner

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this research was to examine how different forms of media, in particular science comics and illustrated texts, contribute to different patterns of learning. While the standard illustrated text seen in a textbook has been a useful tool for instruction, science comics appear to be an alternative that could be used in lieu of media that use the traditional illustrated text format. The comic format, known more for its visual appeal to readers, is consistent with the principles of the Cognitive Theory of Multimedia Learning (Mayer, 2009), though comprehension may require different mechanisms (Cohn, 2013a). It was hypothesized …

An Erp Measure Of Non-Conscious Memory Reveals Dissociable Implicit Processes In Human Recognition Using An Open-Source Automated Analytic Pipeline, Richard J. Addante, Javier Lopez-Calderon, Nathaniel Allen, Carter Luck, Alana Muller, Lindsey Sirianni, Cory S. Inman, Daniel L. Drane

Psychology Faculty Publications

Non-conscious processing of human memory has traditionally been difficult to objectively measure and thus understand. A prior study on a group of hippocampal amnesia (N = 3) patients and healthy controls (N = 6) used a novel procedure for capturing neural correlates of implicit memory using event-related potentials (ERPs): old and new items were equated for varying levels of memory awareness, with ERP differences observed from 400 to 800 ms in bilateral parietal regions that were hippocampal-dependent. The current investigation sought to address the limitations of that study by increasing the sample of healthy subjects (N = 54), applying new …

The Origins Of The Iraq War: The Role Of Anthrax In The Weapons Of Mass Destruction Claims, John P. Koenig

Student Theses and Dissertations

The 2001 Anthrax Attacks were a critical factor in the Weapons of Mass Destruction (WMD) claims that sparked the Iraq War. Despite its significance, little systematic work has been done regarding the topic. Existing studies primarily focus on the role of the Military Industrial Complex and intelligence failures as the primary explanations for the origins of the Iraq War. These explanations are limited, as they rely on hindsight biases. This thesis contends that anthrax was the catalyst for WMD claims that sparked the Iraq War. The 2001 Anthrax Attacks reinforced the belief that Iraq harbored WMDs and posed a threat …

Addressing Vaccine Hesitancy Through A Trust In Science Training Intervention, Nathan Dumessa

All Dissertations

Vaccine hesitancy is an ongoing public health issue that has been underscored by the COVID-19 pandemic and has implications for future pandemics and other vaccines. This research aimed to understand and address the factors associated with hesitancy. Study 1 was a correlational study that measured several factors that could predict vaccine hesitancy among Black and White participants recruited online (n = 364). Findings suggest that trust in science was the strongest predictor of attitudes towards the vaccine’s safety and effectiveness, which in turn strongly predicted vaccine hesitancy. Study 1 established the direct and indirect relationships between several predictors of …

Mechanisms Of False Memories In Bilinguals, Bianca Valentina Gurrola

Open Access Theses & Dissertations

Research on false memory in bilinguals has discovered that false memories can transfer across languages and occur at a higher rate than for within-language false memories (Marmolejo et al., 2009). However, the exact conditions that cause the stronger between-language false memory effect are not clear, nor is it clear how language proficiency influences the production of false memories. The present study had three goals. First, we tested whether the stronger between- language false memory effect relative to the within-language effect would replicate. Second, we examined whether bilinguals could integrate information across languages to form false memories by implementing a mixed-language …

Aggression In And Out Of The Surrounding Space, Marissa Incer

Undergraduate Honors Theses

Social isolation is a type of punishment used to address misbehavior in individuals, such as children with time-outs and prisoners in solitary confinement. It was thought to be an effective method for teaching good behavior or alleviating tense situations. However, this type of punishment may worsen the punished individual’s aggression depending on the environment of isolation. The current study was divided into two experiments. In the first experiment, participants were isolated in a small (2x2 feet) or large (6x6 feet) space to observe if the space alone affected their aggression. In the second experiment, a frustration-inducing task was given to …

Stimulus–Response Congruency Effects Depend On Quality Of Perceptual Evidence: A Diffusion Model Account, Blaine Tomkins

Psychology Faculty Publications

Individuals often need to make quick decisions based on incomplete or “noisy” information. This requires the coordination of attentional, perceptual, cognitive, and behavioral mechanisms. This poses a challenge for isolating the unique effects of each subprocess from behavioral data, which reflect the summation of all subprocesses combined. Sequential sampling models offer a more detailed examination of behavioral data, enabling us to separate decisional and non-decisional processes at play in a task. Participants were required to identify briefly presented shapes while perceptual (duration, size, location) and response features (location-congruent/-incongruent/-neutral) of the task were manipulated. The diffusion model (Ratcliff, 1978) was used …

Cognitive Decline And Contact Sports: The Relationship Between P3 Amplitude And Sub-Concussive Head Impact, Elizabeth Kerman

Undergraduate Honors Theses

The present study sought to explore the effect of repetitive sub-concussive head impacts on the P3 event-related potential (ERP) amplitude and measures of movement kinematics. University students participating in collision, contact, and non-contact sports at the club and varsity level completed a cued visuomotor adaptation task. Results indicated that participants who estimated experiencing four or more sub-concussive head impacts per week display a significantly reduced P3 amplitude across both normal and adaptive trials. Additionally, participants who estimated experiencing less than four sub-concussive head impacts per week displayed no significant changes in P300 amplitude between “switch” and “stay” trials. This research …

The Role Of Attention Control In Automation Performance, Claire Textor

All Dissertations

Research in human-automation interaction has demonstrated that some individuals are more severely impacted by the negative effects of unreliable automation (i.e., exhibit lower performance) than others. A body of work has sought to explain this variability through individual differences, primarily investigating the role of working memory. However, not all studies have demonstrated a clear relationship between working memory capabilities and performance when using automation. Engle’s (2002) controlled attention theory of working memory posits that the relationship between working memory and other cognitive constructs such as fluid intelligence can be explained through a shared reliance on attention control. Studying the role …

The Dynamics Of Emotion-Related Impulsivity: An Analysis Of Emotional Control And Daily Emotion-Driven Urges And Actions Via Ecological Momentary Assessment, Jeremy B. Clift

Graduate Theses and Dissertations

Emotion-related impulsivity, or the engagement in impulsive reactions specifically in response to emotions, has been identified as a crucial transdiagnostic factor. Mixed evidence from ecological momentary assessments (EMA) underscores a potential discrepancy between the existing measurements of emotion-related impulsivity at trait and state levels. Unlike previous EMA studies examining emotion-related impulsivity through measures of urgency, the current study tested Carver and colleagues’ (2008) reflexive responding to emotion framework by investigating the relationship between emotional control and emotion-related impulsivity. Participants (N = 197) with varying levels of emotional control completed one week of EMA to investigate two central questions. First, we …

Memory For Metaphors: Verbatim Memory Held For Literal Sentences Vs. Metaphors, Taylor Suneson

Psychological Science Undergraduate Honors Theses

Certain literary features of text (metaphor, idiom, etc.) are said to be foregrounded, or stand out from the surrounding text. Prior research (Miall & Kuiken, 1994) demonstrates that foregrounded text slows readers down, which is consistent with attention being grabbed. Do features of literary text, more specifically metaphors, improve memory as a result of being foregrounded? The present study investigated the effect of reading metaphoric phrases on reading time, memory accuracy, and decision times. We predicted that when a textual phrase was read as a metaphor, verbatim memory would be better retained than when that same phrase was read as …

The Association Between Mobile Phone Use And Suicidal Ideation, Brendan Wolf

Psychological Science Undergraduate Honors Theses

Research suggests that suicidal ideation can increase among people who feel that they do not belong (i.e. thwarted belongingness) and who perceive themselves to be a burden on others (i.e. perceived burdensomeness). However, it is not known whether these risk factors for suicidal ideation are moderated by smartphone use and social media use. I hypothesized that the association of thwarted belongingness and perceived burdensomeness would be stronger at higher levels of mobile phone use and social media use. Undergraduate student participants (N = 81) were incentivized via class credit to participate in a two-week longitudinal study. They completed questionnaires about …

Updating Of Protagonist Information In Narratives, Luke Mcclanahan

Psychological Science Undergraduate Honors Theses

The purpose of the present research was to further examine contested findings in the research literature surrounding the processes readers use to maintain and update their mental representation of contextual information in a text. Research indicates that whether information is directly relevant to the goal of a story’s protagonist influences whether it will be used as a basis for later validation (Levine & Kim, 2019; Levine & Klin, 2001; Lutz & Radvansky, 1997). Some prior research that indicates that participants fail to validate inconsistent contextual information (Albrecht & Myers, 1995; Smith et al., 2020; Smith & O’Brien, 2012) relies on …

Dancing Bees, Singing Whales. The Impact Of Idiosyncratic Information On Children’S Attitudes Toward And Moral Reasoning About Animals, Vittoria Sipone

Theses and Dissertations

Research in conservation psychology suggests that the tendency to engage in conservation behaviors develops from the interplay of both knowledge of and affinity toward nature (Schmitz & Rocha, 2018; Berenguer, 2007). The present study explores this connection between knowledge and attitudes by investigating the impact of information on individuals' attitudes and care toward animals. This study focuses on knowledge in the form of idiosyncratic information, due to considerations of potential cognitive strengths as well as the pervasiveness of “fun facts” in everyday life. Idiosyncratic information about natural items is not likely to be found in science textbooks at grade-school level, …

The Effect Of Sleep And Emotion On Pattern Separation, Alanna N. Osmanski

UNLV Theses, Dissertations, Professional Papers, and Capstones

Prior work on the relationship between sleep and memory suggests that the sleep state is an optimal time for memory consolidation to occur. During slow wave sleep, newly encoded information in the hippocampus is repeatedly activated, driven by slow oscillations that originate in the neocortex. This process that occurs during slow wave sleep facilitates the long-term storage of memories. A widely accepted view of emotion and sleep is that emotional memories are preferentially consolidated during sleep so that they are easily accessible for retrieval, whereas neutral memories tend to be less accessible. However, recent meta-analyses of sleep, emotion, and memory …

Examining Measures Of Eeg As Biomarkers For Autism Spectrum Disorder, Shuhan Liang

Undergraduate Honors Theses

A central aim of this study was to determine whether there are consistent differences in a variety of ERPs and/or resting state measures of EEG between children diagnosed with ASD and psychiatric controls. Additionally, we aimed to determine whether any of those differences would generalize to the neural correlates of continuous measures of autistic tendencies in the general population. We classified EEG data into three categories: basic sensory responses, cognitive/perceptual ERPs, and resting state measures. Our study indicated that basic sensory responses and cognitive/perceptual event-related potentials (ERPs) did not differentiate autistic individuals from controls. For resting-state measures, the high gamma …

An Evaluation Of Therapeutically Applied Role-Playing Games For Psychological And Social Functioning Amongst Youth/Young Adults, Adam Thomas Soleski

Electronic Theses, Projects, and Dissertations

Tabletop role-playing games (TTRPGs) are “a collaborative narrative game where group members role-play a character that they create in order to solve puzzles, uncover treasure, and defeat monsters in a fictional environment that is created together using formal rules and participation structures'’ (Davis & Kilmer, 2020). TTRPGs have begun to increase in popularity and evoke new interest in exploring whether these new treatment modalities result in positive mental health outcomes. Specifically, therapeutically applied role-playing games (TARPGs) are TTRPGs that integrate therapeutic mechanisms in order to promote improved psychological and social functioning. The goal of the present study was to examine …

Creative Problem Solving Using Visual Thinking, Jacob L. Ravnborg

Creativity and Change Leadership Graduate Student Master's Projects

Creative Problem Solving Using Visual Thinking

This project explores the concept of visual and semantic thinking and how they can be incorporated into Creative Problem Solving sessions. Visual thinking is the ability to conjure mental images as part of the thinking process. This type of thinking is hard-wired into the human brain and can be seen in individual behavior and language. Meanwhile, semantic thinking is using language and grammar to convey meaning. It is a sequential process that depends on cultural and social references. The project argues that both types of thinking are essential and recommends specific guidelines for including …
