Comparing Functional Motor Control And Gait Parameters In Children With Autism To Those Of Age-Matched Peers Who Are Typically Developing, Patricia Stevenson, Samantha Novotny, Jillian May, Christopher Ancell

UNLV Theses, Dissertations, Professional Papers, and Capstones

The purpose of this study was to compare motor performance of children with Autism Spectrum Disorder (ASD) to that of age-matched peers who are typically developing (TD) on motor control tasks plus symmetry and variability of gait parameters across four walking conditions. A sample of convenience of children with ASD (n=6) and peers who are TD (n=6) were recruited. Motor control was assessed using initiation and completion times on the Timed Up and Go (TUG) test. Gait parameters were collected using a computerized walkway under four trial conditions: 1) walking at self-selected velocity (SSV); 2) walking during a tray-carrying task …

Experience-Specific And Domain-General Effects On Simple And Complex Meter Processing, Sangeeta Gupta

UNLV Theses, Dissertations, Professional Papers, and Capstones

Our ability to process rhythmic patterns is constrained by the complexity of its interval structure. The goal of the present study was to explore the cognitive demands and neural mechanisms for processing simple and complex meters, and the extent to which they are modulated by culture-specific experience. The first experiment explored the argument that perception of rhythm is guided by a domain-general ability to process quantity, and that processing simple and complex meter rhythms requires different cognitive strategies. Rhythm perception was assessed by testing listeners’ ability to detect disruptions in simple and complex meter melodies. Proficiency with numerosity judgments was …

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study explored the impact online gaming has on a couples relational intimacy. Gaming has become one of the most popular entertainment Medias in the United States with forty-six percent of American homes having a gaming counsel (Nielsen, 2013). Some of these games are online and gameplay cannot be interrupted and takes up much of the user’s time. Therefore, this study set out to discover if this time commitment had an impact on a relationship’s intimacy levels.

This study used data that had been collected in a previous study and reanalyzed it looking for any correlations between the amount of …

Examining The Role Of Supportive Others In Substance Abuse Treatment And Child Welfare, Jessica Marie Urgelles

UNLV Theses, Dissertations, Professional Papers, and Capstones

Child neglect is a prevalent problem and often co-occurs with parental substance abuse. Mothers are most often the perpetrators of child neglect. The currently available treatment programs appear to be failing to meet the needs of these mothers. Most mothers are not completing treatment, putting them at risk of losing custody of their children. The literature suggests that women may have different risk factors associated with their substance use, as compared to men. Social networks appear to play a particularly important role in the maintenance of women’s substance abuse problems. The role of social networks may be distinct for different …

Functional Capacity In Schizophrenia: Relationship Among Effort, Reinforcement Learning And Self-Beliefs, Sally J. Vogel

UNLV Theses, Dissertations, Professional Papers, and Capstones

Individuals with schizophrenia exhibit a wide range of complex neurocognitive, psychiatric and behavioral impairments. Recent research suggests that this complex array of symptoms can be at least partially accounted for by dysfunction in more basic mechanisms, such as the ability to learn from positive and negative reinforcement, or the ability to exert adequate effort when completing simple tasks. Evidence also suggests that deficits in these basic mechanisms may contribute to more complex symptoms, such as functional impairment. Also, the relationship between neurocognitive deficits and functional impairment has been found to be mediated by defeatist performance beliefs. However, studies have not …

Methods Of Teaching Social Intelligence And Its Impact On Service Quality, Martee Fischman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Current literature on social intelligence was reviewed and analyzed and most was focused on the general understanding of social intelligence and methods of measurement. There is little literature that connects social intelligence to the business world and none that focuses on the hospitality industry. It is important to fill the gap in research because social intelligence could have a significant impact on service quality, which in turn affects revenues. The current literature provides a good foundation, but more research is needed in the hospitality industry to determine the impact social intelligence actually has on service quality. Experimentation utilizing several measurement …

Preferences For Evidence-Based Depression Treatments: An Emphasis On Patient-Focused Care, Lauren A. Frye

Dissertations

Research indicates most depressed patients in the general U.S. adult population seek depression treatment in primary care settings where the prevailing method of treatment is antidepressant medication. Although primary care physicians regard this approach as a preferable first line method of depression treatment, studies indicate many patients do not. Several studies have found depressed patients in these settings prefer psychotherapy or counseling over anti-depressant medication. Many advocate patient preferences should be integral to the treatment decision making process. There is a demonstrated propensity towards psychotherapy or counseling over antidepressant medication among depression patients. However, it is unclear which psychological depression …

The Effects Of Incentive Pay Systems With Tiered Goals On Performance, Daniel B. Sundberg

Dissertations

This study examined the relative effects of three incentive pay systems, piece-rate pay, threshold piece-rate pay, and bonus pay, on performance when individuals were given the same five-tiered performance goals. A fourth system, wage pay, served as a control. The task was a computerized simulation of a medical data entry job and the primary dependent variable was the number of correctly completed patient records. Sixty-six college students were randomly assigned to one of the four pay conditions, and attended one 60-minute covariate session and five 60-minute experimental sessions. Participants in the wage pay condition earned $6.50 per session; those in …

The Relationship Of Cell Phone Usage To Personality And Attention, Victoria L. Grajeda

Senior Theses

Cell phones seem to create distraction and anxiety in student’s daily lives. The present study tests if distraction would occur just by the ring from a cell phone (i.e. they will score lower on the lecture quiz). The procedure will include 40 students enrolled in two sections of Introduction to Psychology. In one section, a backpack will be situated on an empty desk with a cell phone inside which is set to ring during a normal classroom lecture. Once the lecture ends (in both sections), a quiz will be issued about the PowerPoint including slides showing during the cell phone …

Depression And Social Functioning : Examining Two Interpersonal Theories, Caroline B. Smith

Honors Theses

The purpose of this study was to test the specific predictions of two theories of depression and social functioning. One, the Social Navigation Hypothesis, is an adaptationist approach that predicts that depression functions to increase an individual’s ability to analyze and solve problems in their social system. The individual engages in behaviors such as feedback seeking in order to identify potential problems and develop solutions. In contrast, Interpersonal Theory predicts that depression is related to aversive social behaviors that can lead to rejection. Adult American participants (n=155) were recruited from Amazon’s Mechanical Turk. They completed an online survey …

The Relationship Between Receptacle Design, Normative Conduct, Environmental Concerns, And Recycling Behavior, Molly Arnold

Honors Theses

Conservation psychology is a growing field that explores how people interact with and interpret their roles in the environment. I conducted a three part study that incorporates conservation psychology principles to examine the effects of recycling bin design and normative conduct on recycling behavior as well as the ecological orientation of UTC students based on survey responses. Experiment 1 compared two recycling bin conditions (non-lidded bin vs. bin covered with a lid with two holes indicating the shape of recyclables) to determine which bin design was more effective in promoting recycling behavior. No difference was found between the two designs. …

Sport-Related Head Injury And Performance Anxiety, Haley V. Popp

Honors Theses

Head injury in sport is a highly individualized experience; the symptoms and persistence tend to differ widely between athletes. Neurocognitive deficits in head injury may be worsened by the emotional reaction of the athlete to the injury. Athletes that are removed from play due to musculoskeletal injuries tend to be anxious about becoming reinjured are more likely to be depressed and may have low attention and reaction time. Emotions that result from removal from play can have emotional, psychosocial, and career implications for the athletes. Despite this, there is a lack of literature directly examining the impact of head injury …

Lindenwood Students’ Cultural Domain Of Female Beauty, Courtney Cox

Undergraduate Psychology Research Methods Journal

In this study, the shared cultural domain of female physical beauty on the Lindenwood campus was identified. A cultural domain is essentially, “things that somehow go together” (Bernard 2006, p. 299). The domain is established by systematic use of free lists, a method in which participants list all of the attributes that they can in response to a prompt. A written free list method was selected so that a large group of students could provide their data in a quick and anonymous manner. In this case, the domain of interest was “attributes that are physically beautiful in women.” After providing …

Relationship Between Social Category And Third-Party Perceptions Of Crime, Sara Roderick

Undergraduate Psychology Research Methods Journal

How social category affects observer perceptions of crime is an interesting topic that can yield many interesting results. Previous research has shown that the social category of individual can hold some influence on how the individual is perceived. Some studies focused on the dispositional qualities attributed to individuals solely based on social category, while other were more concerned with third-party responses to individuals based on social category. Within that same line, this study hoped to replicate findings by Lieberman and Linke (2007) which indicated that the social category of a perpetrator of a crime did indeed have an effect on …

The Neuroendocrine And Performance Correlates Of Posttraumatic Stress Disorder In Males And Females, Meghan E. Pierce

UNLV Theses, Dissertations, Professional Papers, and Capstones

Distinct gender differences exist in the incidence of posttraumatic stress disorder in the United States population. Currently, the direct biological mechanisms involved in the development of PTSD have not been elucidated. However, many studies indicate a dysregulation of the hypothalamic-pituitary-adrenal axis (HPA-axis) as a contributing factor in the development of PTSD. This study investigated performance and endocrine correlates of PTSD in 38 females without PTSD, 14 females with PTSD, 32 males without PTSD and 5 males with PTSD. We examined the differences between basal cortisol concentrations, as well as cortisol reactivity to the Trier Social Stress Test (TSST). In addition, …

Contrasting Perceptions Of Motivation To Change: Clinicians And Substance Abuse Clients, Arthur Tabrizi

UNLV Theses, Dissertations, Professional Papers, and Capstones

Substance abuse persists as one of the most costly, prevalent, and damaging health problems in the United States. As of 2012, an estimated 22 million individuals, approximately 8.9 percent of the total population, were diagnosed with substance abuse or dependence disorder. Considering the significant number of clients served, successful national completion rates among individuals utilizing outpatient care remain markedly low. In the state of Nevada, where the present study is conducted, successful intensive outpatient treatment (IOP) completion rate remains at an alarmingly low 20.1 percent. Early dropout is a particular concern in that duration of participation in treatment has been …

Presence-At-Hand, Eric Lyle Schultz

Graduate School of Art Theses

Abstract

The writing that follows is intended to provide a theoretical framework for the motives behind my practice. The primary concerns addressed are the reception, transmission, and physical shape of knowledge. I will discuss a human condition that exists as a byproduct of both the legacy of representation as well as the innate biology of the brain. I will argue that as a society we are governed by the residue of an extreme logic, and that this condition places severe margins on our potential for creative solutions. I will propose that our ability to create meaning is stifled by the …

Are Women Higher In Anxiety Than Men? United States Surveys, 2003‐2013, Rabale Hasan

Honors Scholar Theses

A large proportion of the U.S. population suffers from anxiety and related mental illnesses. An in-depth analysis needs to examine all possible factors that may explain why anxiety is on an upward trend and why women are more likely than men to present with anxiety. This study examined the anxiety in five cross-sectional United States surveys (Total N=19,630) taken in 2003, 2006, 2009, 2011, and 2013. Predictors such as demographics (e.g., race, age, gender), medical conditions, behavioral choices (e.g., BMI, exercise, sleep), and psychosocial stressors were investigated. Linear regression and logistic regression analyses were used to examine trends. Anxiety is …

Oscillatory Activity In The Subthalamic Nucleus And Motor Cortex In A Pharmacological Model Of Parkinsonian Tremor, Aileen F. Haque

Honors Scholar Theses

Parkinson’s Disease (PD) is a motor disorder with symptoms including resting tremor, akinesia, bradykinesia, and rigidity. A major neuropathological feature of PD is degeneration of nigrostriatal dopamine (DA) neurons. The resulting DA depletions lead to the production of severe motor deficits. Pharmacological agents that reduce DA transmission can also induce these motor abnormalities. In addition to the involvement of DA, drugs acting on acetylcholine, namely cholinomimetics, can induce or exacerbate Parkinsonian symptoms. In humans, one of the main motor symptoms associated with PD is resting tremor, occurring at a frequency of 3-7 Hz. This can be modeled in rodents using …

Central Auditory Processing And The Link To Reading Ability In Adults, Lisa M. Brody

Honors Scholar Theses

What makes someone a good reader? What makes someone a poor reader? The root biological marker of reading ability has yet to be determined. Many scientists agree that phonological awareness, the understanding of speech sounds, and phonological decoding are key components of reading ability (Melby-Lervag, Lyster, & Hulme, 2012). In addition to this, new research suggests that the auditory system, specifically the timing of auditory processing in the brain, provides a crucial platform that supports the development of reading ability (Banai et al., 2009). This thesis provides empirical data to support the link between reading skill …

Understanding The Psychology Of Bullying: Moving Toward A Social-Ecological Diathesis–Stress Model, Susan M. Swearer, Shelley Hymel

Department of Educational Psychology: Faculty Publications

With growing recognition that bullying is a complex phenomenon, influenced by multiple factors, research findings to date have been understood within a social-ecological framework. Consistent with this model, we review research on the known correlates and contributing factors in bullying/victimization within the individual, family, peer group, school and community. Recognizing the fluid and dynamic nature of involvement in bullying, we then expand on this model and consider research on the consequences of bullying involvement, as either victim or bully or both, and propose a social-ecological, diathesis– stress model for understanding the bullying dynamic and its impact. Specifically, we frame involvement …

The Effects Of Electronic Response Systems On Student Learning, James D. Morrison

Masters Theses

One of the most technologically advanced methods of implementing active student responding is the electronic response system (Judson & Sawada, 2002). This technology is known under several names including audience response system, classroom response system, and colloquially as clickers (Smith, Shon, & Santiago, 2011). To accurately assess the impact of clickers on learning performance and classroom achievement, more quantitative analysis and systematic replication of studies was needed (Kay & LeSage, 2009). This study examined the effects of ASR questions on exam performance in two sections of an organizational psychology class for majors and non-majors. A social validity questionnaire was also …

Reducing Disruptive Behavior In High School: The Good Behavior Game, William Blake Ford

Master's Theses

Disruptive behavior in the classroom setting negatively impacts the learning process in various ways, interfering with the educational process of individual students, the teacher, and/or the class as a whole. Class-wide levels of disruptive behaviors worsen these impacts and are often related to problems with a teacher’s classroom management techniques and abilities. Group contingency interventions, such as the Good Behavior Game (GBG), are often used to provide teachers with evidence based management strategies while improving student behavior in the class. Furthermore, group contingency interventions, such as the GBG, can be conceptualized as Tier I or Tier II interventions within a …

Physical Disability And Suicidal Desire: An Examination Of The Constructs Of The Interpersonal-Psychological Theory Of Suicide, Lauren Rachel Khazem

Master's Theses

The primary aims of this study were to examine constructs of the Interpersonal-Psychological Theory of Suicide (IPTS) in an understudied population. Differences in levels of IPTS variables and suicidal ideation between university students with and without physical disabilities were examined. Participants were 184 students from two Southern universities who provided answers to online-based self-report questionnaires. It was hypothesized that students with physical disabilities would endorse higher levels of all IPTS constructs relative to students without physical disabilities. It was further hypothesized that disability status would exhibit an indirect effect on suicidal ideation through perceived burdensomeness and thwarted belongingness. Results indicated …

Personality, Character Strengths, Empathy, Familiarity And The Stigmatization Of Mental Illness, Jessica Shanna James

Master's Theses

The stigma associated with mental illness is pervasive and detrimental. The aim of the current study was to assess individual characteristics that may be positively and negatively associated with the stigmatization of mental illness. Two-hundred fifty-nine undergraduate students from the University of Southern Mississippi completed measures of the Big Five personality traits (i.e., Agreeableness, Extraversion, Conscientiousness, Neuroticism, and Openness to Experience), Dark Triad personality traits (i.e., Machiavellianism, Narcissism, and Psychopathy), selected character strengths (i.e., Open-mindedness, Perspective, Bravery, Integrity, Kindness, Social Intelligence, Fairness, Forgiveness and Mercy, and Hope), Empathy, and Familiarity with mental illness. Participants also completed measures of stigmatizing attitudes …

The Impact Of Relational Training Of Preferred Food And Non-Preferred Food To Arbitrary Symbols On Implicit Relational Tasks, Janelle Antoinette Allison

Theses and Dissertations

The Mixed-Trial Implicit Relational Assessment Procedure (MT-IRAP) is a tool for measuring implicit behavior (i.e., biases or beliefs the individual is unaware of or intends to conceal from the public) among individuals. The MT-IRAP is a modified version of the Implicit Relational Assessment Procedure (IRAP) and was designed to address limitations inherent to the IRAP’s design. The MT-IRAP was tested with adult participants across a series of five studies. Throughout each study, the MTIRAP assessed implicit behavior toward high-preferred foods, non-preferred foods, and arbitrary symbols. The experimenter administered the MT-IRAP before and after participant completion of a task designed to …

Inverse Changes In Ghrelin And A2a Receptor Gene Expression Levels In The Hippocampus Of Heart Failure Canines Following Spinal Cord Stimulation, Benjamin E. Jewett

Undergraduate Honors Theses

Myocardial infarction (MI), often referred to as a heart attack, is a serious health issue in the United States. There is a well-documented link between MI and major depressive disorder (MDD), with a high incidence of MDD occurring after an MI. Overlapping pathologies have been observed within the hippocampus of the brain in animal models of MI and depression. These observations suggest that pathobiological cross-talk between the heart and brain could have a role in the etiology of MDD that occurs after an MI. Spinal cord stimulation (SCS) has previously been shown to have both cardioprotective and neuroprotective effects post-MI, …

The Synergistic Effects Of Methylphenidate On The Behavioral Effects Of Nicotine, Kristen K. Leedy

Undergraduate Honors Theses

One of the most common childhood disorders, attention-deficit hyperactivity disorder (ADHD) places individuals at a higher risk for nicotine (NIC) dependence. Approximately 37.2% of individuals with ADHD currently smoke compared to the 18.3% of individuals with no record of mental illness. Methylphenidate (MPH; Trade name Ritalin) is the most commonly prescribed treatment for ADHD. Research regarding the synergistic effects of MPH and NIC, however, is divided. Some research indicates that MPH may enhance susceptibility to NIC effects, whereas other studies report that MPH may inhibit sensitization to NIC. The present study examines the effects of pre-exposure to MPH (1.0 mg/kg) …
