The Hormonal Correlates Of Stress And Posttraumatic Stress Disorder Symptoms In Female Veterans, Meghan Pierce

UNLV Theses, Dissertations, Professional Papers, and Capstones

With the increase of female veterans serving in the military, a better understanding of posttraumatic stress disorder is needed to provide comprehensive treatment. This study examines salivary cortisol in female veterans with PTSD, female veterans without PTSD, civilian females with PTSD and healthy controls. The Posttraumatic Stress and Beck Depression Inventory-II were used to assess posttraumatic stress and depressive symptoms. Saliva samples were collected at bedtime and awakening, as well as in response to the Trier Social Stress Test. Significant results were not found for diurnal cortisol levels [ F (3, 11)= .979, p < .05] or stress cortisol levels (F (3,12) = 1.140, p >.05). …

Executive Function Profiles In Pediatric Traumatic Brain Injury, Erik Nelson Ringdahl

UNLV Theses, Dissertations, Professional Papers, and Capstones

Traumatic brain injury is a common cause of disability and death among children in the United States. Insult to the frontal and temporal lobes are frequent in closed head brain injury. Cognitive deficits in a variety of domains are common sequelae of brain trauma. In many cases, trauma to the frontal and temporal lobe regions engender prominent deficits in higher-order cognitive processing, memory, and attention.

Higher-order cognitive processing, or Executive Functions are the grouping of cognitive processes necessary for organization of thoughts and activities, attending to the activities, prioritizing tasks, managing time efficiently, and making decisions (Alvarez & Emory, 2006; …

International Study Program For Indoor Environmental Research, Stoil Pamoukov

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study examined the effect on student performance, perception and mood caused by different physical classroom environmental conditions. Three classroom physical environmental conditions were investigated; room temperature, light intensity and sound level. A two phase pilot study was performed where these conditions were compounded into one and two levels were selected in such a way to create a normal and extreme classroom physical environment. A total of 154 undergraduate UNLV students participated in the two phase pilot laboratory study in which they completed tasks related to reading and listening to an oral presentation of a passage of high density technical …

The Self: Your Own Worst Enemy? A Test Of The Self-Invoking Trigger Hypothesis, Bradley J. Mckay

UNLV Theses, Dissertations, Professional Papers, and Capstones

The self invoking trigger hypothesis was recently proposed by Wulf and Lewthwaite (2010) as the mechanism underlying the robust effects of attentional focus on motor learning and performance. The hypothesis suggests that causing individuals to access their self schema will negatively impact their ability to learn and perform a motor skill. The purpose of the present study was to provide an initial test of this hypothesis by causing one group of participants to activate their self schema in a straightforward manner. Participants (N = 32) were assigned to either a self-activated or control condition and asked to practice a wiffleball …

The Development And Evaluation Of A Safety Skill Intervention For Child Victims Of Neglect, Heather H. Hill

UNLV Theses, Dissertations, Professional Papers, and Capstones

Child neglect is the least studied, yet most frequently indicated, type of child maltreatment. Still, there are few assessment and treatment methods specifically designed for victims of child neglect. Unintentional injuries have long remained the leading cause of death for children in the United States after the first year of life, and research suggests the majority of these child fatalities are actually the result of child neglect. Homes of neglectful families are often inundated with safety hazards but child-focused home safety skill interventions have yet to be developed. Thus, the present study focused on the development and initial evaluation of …

The Dilemma Of Minors’ Access To Adult Content On The Internet: A Proposed Warnings Solution, Helen Zaikina-Montgomery

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Internet can be a dangerous place for children. Because minors have unrestricted access to adult content, a system of warnings targeting minors on the Internet should be developed. The present studies tested icons for such a system and subsequently to examined selected icons in combination with signal words, color, and warning messages. One hundred and ninety three adults and eleven children participated in the first study. Participants rated thirty eight icons created by the researcher for their understandability, carefulness, attention-getting, likelihood of encountering and severity of danger, likelihood of avoidance and familiarity. Familiar icons were found to be rated …

The Effect Of Working Memory And Math Ability On Decision Making, Jeremy A. Krause

UNLV Theses, Dissertations, Professional Papers, and Capstones

Previous research has indicated that people use various strategies when making decisions. A majority of the research has involved the idea that people use a heuristic when making decisions. Kahneman and Tversky have illustrated that there are instances that people respond with an answer that appears to be indicative of usage of the representativeness heuristic. One of the purposes of the current paper is to gain insight into the actual strategies that are used in these instances. Another purpose of the current experiment is to see if math ability and working memory capacity influence the strategy that a person selects …

Playing With Fire Or Arson? Identifying Predictors Of Juvenile Firesetting Behavior, Mary Ellen Britt

UNLV Theses, Dissertations, Professional Papers, and Capstones

Firesetting is a complex behavior that spans a wide range of developmental stages in childhood and adolescence and involves varying motivations and intents. A better understanding of this destructive behavior is critical to developing strategies to control its devastating effects. The purpose of this research project was to identify potential predictors of juvenile firesetting behavior by studying youth who were enrolled in a regional firesetting intervention program. Data collected from firesetting assessment instruments completed by parents or guardians of program participants were examined. In the analyses, special emphasis was placed on evaluating associations between juvenile firesetting behavior and the socioeconomic …

Bilingualism And Math Cognition, Michelle M. Guillaume

UNLV Theses, Dissertations, Professional Papers, and Capstones

Within cognitive psychology, the fields of bilingualism and math cognition have been investigated relatively separately from one another. Although there has been a substantial amount of research conducted in both areas, few studies have examined mathematical processes as they relate to bilinguals. A couple of the traditional effects found in the math cognition literature, the problem size and associative confusion effects, have been studied with bilinguals; however, bilingual categorization was not carefully controlled for in those studies. There have also been mathematical models applied to bilingual samples; one such model is the encoding-complex model, which has been extended to Chinese-English …

To Consult Or Not To Consult? Investigating Barriers To Dysparenia Treatment-Seeking In Young Women, Robyn L. Donaldson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Little is known about mediators of treatment-seeking in dyspareunia. The general health belief literature as well as some existing qualitative data specific to dyspareunia, however, suggests a number of potentially significant barriers that may delay or prevent women from enlisting the aid of health care professionals. The aim of this study was to investigate influences on dyspareunia treatment-seeking behavior in young women, for whom the consequences of treatment avoidance are hypothesized to be the greatest. Given the lack of standardized health behavior measures relevant to intercourse pain, we constructed a measure assessing potential barriers to dyspareunia treatment-seeking. An exploratory principal …

Operation Span Task’S Susceptibility To Math Anxiety: Support From Fluid Intelligence, Robert T. Durette

UNLV Theses, Dissertations, Professional Papers, and Capstones

This experiment tested possible math anxiety effects on the two most prominent working memory span tasks, the operation span and reading span tasks. Math anxiety effects on the performance of the processing component of the operation span task, which is math based, were found, but not on the processing component of the reading span task, which is reading based. High math anxious individuals were the largest group of individuals that failed to meet the prescribed 85% accuracy threshold of the processing component of the operation span, countering the hypothesis that not meeting the threshold score is due to a lack …

The Effect Of Early Environmental Manipulation On Locomotor Sensitivity And Methamphetamine Condition Place Preference Reward, Emily Hensleigh

UNLV Theses, Dissertations, Professional Papers, and Capstones

Early life stress has drastic effects on neurological development, affecting health and well-being later in life. Instances of child abuse and neglect are associated with higher rates of depression, risk taking behavior, and an increased risk of drug abuse later in life (Chapman,D.P. 2004; Dube,S.R. 2003). This study used repeated neonatal separation of rat pups as a model of early life stress. Rat pups were either handled and weighed as controls or separated for 180 minutes per day during postnatal days 2-8. In adulthood, rats were tested for methamphetamine conditioned place preference reward and methamphetamine induced locomotor activity. Tissue samples …

Personality, Presence, And The Virtual Self: A Five-Factor Model Approach To Behavioral Analysis Within A Virtual Environment, Michael Patrick Mccreery

UNLV Theses, Dissertations, Professional Papers, and Capstones

For several decades, researchers have explored the existence of the virtual self, or digital embodiment of self found within an avatar. It was surmised that this new component of one’s overall identity not only existed in conjunction with the public and private persona, but was replete with the necessary physical and psychological characteristics that facilitate a broad range of cognitive, cultural, and socio-emotional outcomes found within a virtual environment (e.g., Second Life, World of Warcraft). However, little is known with regard to whether these characteristics do indeed impact behavioral outcomes. For this reason, this study employed an observational assessment method …

Testosterone And Vasopressin In Men’S Reproductive Behavior, Eric T. Steiner

UNLV Theses, Dissertations, Professional Papers, and Capstones

One common practice used by researchers is to divide human reproduction into two major domains: mating and parenting. Adaptive problems men faced over the millennia may have produced evolutionary pressure for hormone responses and behavior that facilitate both mating and parenting, either separately or simultaneously. The sometimes competing domains of mating and parenting in men are often mediated by a number of the same hormones, such as testosterone (T) and arginine vasopressin (AVP). One aim of the current study was to examine differences in baseline levels of T and AVP between childless men who were not in an exclusive, romantic …

Cognitive Load Of Critical Thinking Strategies, Hanem Shehab

UNLV Theses, Dissertations, Professional Papers, and Capstones

Critical thinking is important for today's life, where individuals daily face unlimited amounts of information, complex problems, and rapid technological and social changes. Therefore, critical thinking should be the focus of general education and educators' efforts (Angeli & Valanides, 2009; Oliver & Utermohlen, 1995). Despite passively agreeing or disagreeing with a line of reasoning, critical thinkers use analytical skills to comprehend and evaluate its merits, considering strengths and weaknesses. Critical thinkers also analyze arguments, recognizing the essentiality of asking for reasons and considering alternative views and developing their own point of view (Paul, 1990). Kuhn and Udell (2007) emphasize that …

School Refusal Behavior: The Relationship Between Functions And Symptom Sets, Marisa Charlene Hendron

UNLV Theses, Dissertations, Professional Papers, and Capstones

The current study examined the relationship between functions of school refusal behavior and internalizing and externalizing symptom sets in a community sample of 200 youth and parents recruited from two truancy settings. The first hypothesis was that youth who endorsed refusing school primarily to avoid stimuli that provoke negative affectivity (function 1) would report more symptoms of generalized anxiety and depression. The second hypothesis was that youth who endorsed refusing school primarily to escape from aversive social or evaluative situations (function 2) would report more symptoms of social anxiety. The third hypothesis was that youth who endorsed refusing school primarily …

Attachment And Couple Sexual Functioning, Kathryn Z. Devis, Melissa A. Louder, Kara L. Thompson, Katherine M. Hertlein

Graduate Research Symposium (GCUA) (2010 - 2017)

Within the last several years, there has been a surge in the publications that focus on attachment within the couple relationships, including how it pertains to infidelity treatment. Despite the interest in couple relationships and attachment, however, a limited amount of literature focuses on how varying styles of attachment manifest in a couple's level of sexual functioning. This study is a response to the need to explore the literature and related gaps in literature.

Driving Forces: Police Fatalities, Carol Servino

Graduate Research Symposium (GCUA) (2010 - 2017)

Law enforcement is an inherently risky occupation. The number of traffic-related fatalities for law enforcement officers in the U.S. during the past 13 years has been increasing; however, the number of fatalities for the general population in motor vehicle traffic incidents declined during the same time period.

The federal government reports that federal motor vehicle safety standards aswell as behavioral and vehicle safety programs implemented by state and local law-enforcement agencies contributed to the downward trend for the general public.

What accounts for the pattern and problem with police driving-related deaths?

Decision-Making Techniques Used By Elected Officials, Michael Gordon

Graduate Research Symposium (GCUA) (2010 - 2017)

Politicians often make decisions that lead to contradictory outcomes from situations with seemingly similar circumstances and related factors. Recent examples include the U.S. reaction to the uprising in Iran contrasted with the call for the ousting of president Hosni Mubarak after the 18 Day Revolution in Egypt.

This frustrating reality, frequently based on perceived risks of publication of state secrets, has various far-reaching effects. Two effects of this reality include the loss of trust in government and government officials to do the right thing as well as the frequency of market fluctuations.

Clark County Mental Health Court: An Outcomes-Based Evaluation Model Of Residential And Treatment Programs Beyond Recidivism, Mark J. Nichols

Graduate Research Symposium (GCUA) (2010 - 2017)

The number of America’s mental health courts has grown significantly over the course of the past 15 years. Mental health courts can be seen as a form of therapeutic jurisprudence where the court implements therapeutic interventions, case management and treatment (Palermo, 2010). A mental health court was established in Clark County during 2003. Its mission is to promote engagement in treatment, improve quality of life, decrease recidivism, and increase community safety and awareness (Glass, 2008).

The focus of the evaluation of the Clark County Mental Health Court, limited to performance measures related to the decreased recidivism by its clients and …

The Effects Of Working Memory On High And Low Working Memory Capacity, Colleen M. Parks, Christine Agnir

Festival of Communities: UG Symposium (Posters)

Acute stress is a factor that impairs working memory (McHugh et al.,2010). Emotional stimuli have been used in long-term memory studies. The emotional content of information is important in long-term memory studies that have focused on stress, but it is unknown if the valence of the stimuli matter for working memory tasks. Little research is know to use emotional pictures of N-back stimuli. Our goal is to determine whether these factors may significantly disrupt the working memory process of efficiently completing complex tasks.

Relationship Between Perceived And Actual Quality Of Data Checking, Hunter Speich, Sophia Karas, Dan Erosa, Kelly Grob, Kimberly A. Barchard

Festival of Communities: UG Symposium (Posters)

Data quality is critical to reaching correct research conclusions. Researchers attempt to ensure that they have accurate data by checking the data after it has been entered. Previous research has demonstrated that some methods of data checking are better than others, but not all researchers use the best methods. Perhaps researchers continue to use less optimal data checking methods because they mistakenly believe that they are highly accurate. The purpose of this study was to examine the relationship between perceived data quality and actual data quality. A total of 29 participants completed this study. Participants checked that letters and numbers …

Learning Mechanisms For Acquiring Knowledge Of Tonality In Music, Rikka Quam, Matthew Rosenthal, Erin Hannon

Festival of Communities: UG Symposium (Posters)

Most people think that musical knowledge is exclusive to trained musicians. Actually, casual music listeners have implicit knowledge of important structural aspects of music, such as tonality. Tonality contributes to the feeling of anticipation one would experience when hearing someone sing “do re mi faso la ti” without singing the final “do”. Knowledge of tonality may be learned through the statistics of music (Krumhansl, 1990). However, learning mechanisms have rarely been investigated experimentally (Creel et al., 2002). Artificial grammar learning experiments have shown that listeners can acquire highly structured knowledge such as syllable co-occurrence and language syntax through passive exposure. …

Examining The Construct Validity Of The Metaphors Test, Jane Park, Kelly Grob, Yevgeniya Verenikina, Kimberly A. Barchard

Festival of Communities: UG Symposium (Posters)

Emotional Intelligence is a multi-faceted construct. Existing tests do a good job of measuring some aspects of Emotional Intelligence. The Metaphors Test (Barchard, 2004) was designed to measure the ability to decipher the emotional content of ambiguous sentences. This test may measure a new facet of Emotional Intelligence. The purpose of this research was to examine the construct validity of the Metaphors Test as a measure of Emotional Intelligence. Using a sample of 281 undergraduates, the Metaphors Test was correlated with the four branches of the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT; Mayer, Salovey, & Caruso, 2004): Perceiving Emotions, Using Emotions …

Analysis Of Morris Water Maze Data With Bayesian Statistical Methods, Maxym V. Myroshnychenko, Anton Westveld, Jefferson Kinney

Festival of Communities: UG Symposium (Posters)

Neuroscientists commonly use a Morris Water Maze to assess learning in rodents. In his kind of a maze, the subjects learn to swim toward a platform hidden in opaque water as they orient themselves according to the cues on the walls. This protocol presents a challenge to statistical analysis, because an artificial cut-off must be set for those experimental subjects that do not reach the platform so as they do not drown from exhaustion. This fact leads to the data being right censored. In our experimental data, which compares learning in rodents that have chemically induced symptoms of schizophrenia to …

How Experience Influences Infants’ Recognition Of Male And Female Faces, Jennifer L. Rennels, Veronica A. Glover, Andrew J. Cummings, Andrea J. Kayl, Mateusz Orlewicz, Roanne J. Tiongson, Brooke Ditzler

Festival of Communities: UG Symposium (Posters)

Young infants with female primary caregivers are able to differentiate familiar female faces from novel female faces but not male faces. Experience processing faces may be important for being able to discriminate among similar-looking faces. Subsequently, increasing infants’ experience with less familiar faces should improve their ability to differentiate those types of faces. This study examined if infants’ experience with faces affected their recognition of new faces. Prior to testing, 2-3 month old infants were assigned to one of three conditions: a male video, a female video, and no video condition. Infants were familiarized to both male and female faces …

Can Female Genital Mutilation Victims Benefit From Corrective Surgery: To Regain Sexual Pleasure And Be “Whole” Once Again?, Monique Sulls

Festival of Communities: UG Symposium (Posters)

Female Genital Mutilation (FGM) is defined by the World Health Organization, (WHO), as the removal or cutting of the external female genitalia. WHO estimates between 100 and 140 million girls and women worldwide currently live with the consequences of FGM. The study finds that through corrective surgery, pre/post therapy, counseling, and sexual education victims to FGM can regain sexual pleasure providing them a chance to be “Whole” once again.
