Formant Frequency Transitions In The Fluent Speech Of Adults Who Do And Do Not Stutter: Testing The Over-Reliance On Feedback Hypothesis, Kaitlin Arnold

Masters Theses

A recent theory proposed by Civier and colleagues (Civer et al. 2010; Civer et al. 2013) developed a model of stuttering that implicates a faulty feedforward control system. The hypothesis suggests that stuttering results from relying too heavily on sensory feedback to guide speech movements. An overreliance on sensory feedback would result in subtle anomalies in fluent speech (such as slowed articulatory transitions) as well as overt stuttering behaviors (such as sound repetitions). The present study tested this general hypothesis by comparing articulatory transition rates of adults who do and do not stutter across casual and fast speech rates. Participants …

Effects Of Altering Motivation In Pigeons Performing A Titrating-Delayed-Matching-To-Sample Task, Zachary J. Zimmermann

Masters Theses

In order to better understand the role motivating operations (MOs) serve in preceding and evoking behavior, it is useful to examine the effects of whether manipulating motivation can influence performance on tasks with known behavioral outcomes. It is well established that altered stimulus control is responsible for changes in responding on tasks of generalization and discrimination. Therefore, if stimulus control could be influenced by MOs, then perhaps stimulus discriminations could be improved by manipulating the relevant MO. To this end, the effects of altering motivation via food deprivation were examined in pigeons using a titrating-delayed-matching-to-sample task. Additional pharmacological variables (i.e., …

From “Black Is Beautiful” To “Gay Power”: Cultural Frames In The Gay Liberation Movement, Eric Denby

The Hilltop Review

In lieu of an abstract, a short excerpt is provided:

"

The 1960s and 1970s were a decade of turbulence, militancy, and unrest in America. The post-World War II boom in consumerism and consumption made way for a new post-materialist societal ethos, one that looked past the American dream of home ownership and material wealth. Many citizens were now concerned with social and economic equality, justice for all people of the world, and a restructuring of the capitalist system itself. According to Max Elbaum, the traditional narrative of the 1960s begins with an “idealistic, impassioned” youth working on voter registration …

Free Zone Scientology: The Social Structure Of A Contemporary Reform Movement, Kyle D. Byron

The Hilltop Review

In lieu of an abstract, a short excerpt is provided:

"

The Church of Scientology has a notorious history of controversy. The sources of this controversy stem from both the legal realm (most notably in the acquisition of the legal label of “religion” and, therefore, tax exempt status) and the social sphere, with critics from both the Christian and secular “anti-cult” movements publishing polemics against the Church. There also, however, exists a third source of criticism: self-identified Scientologists who have chosen to leave the official institution of Scientology. These understudied groups, practicing outside of the Church, are known as …

Reproductive Genetics: Desired Genes, Gendered Ethics, And Eugenic Echoes, Marykate K. Bodnar

The Hilltop Review

Present knowledge of genetics and assisted reproduction make fertile ground for a new type of eugenics: reproductive genetics. Proponents of reproductive genetics aim to separate these techniques from the problematic and negative connotations associated with historical eugenic policies by claiming them as part of the liberal eugenic movement. In-vitro fertilization (IVF), the market for sperm and eggs, and prenatal genetic testing allow conscious decision-making regarding the potential genetic make-up of children. Decisions are made in a gendered and politicized environment, shaping understandings of genes, eggs, and sperm around stereotypes and ideal social norms. In choosing “desirable” characteristics, whatever they may …

The Effects Of Humorous Facebook Posts On Messenger Credibility And Social Attractiveness, Brett A. Stoll

The Hilltop Review

The purpose of this study was to determine the effect that humorous Facebook messages have on perceived source credibility and social attractiveness. Social networking sites (SNS) such as Facebook continue to rise in popularity, solidifying their ongoing presence and influence for the foreseeable future. As users continue to look for ways to manage interpersonal impressions online, many turn to humor in public wall posts and message feeds. With humor proliferating the content of nearly 20% of Facebook posts, it begs the question of what effect its use has on impression management. To address this question, the researcher asked 283 participants …

Functional Analysis Of Gambling, Mack S. Costello

Dissertations

Given high rates of gambling and the growing population of disordered gamblers, there is a need to develop assessment strategies with improved treatment validity. More specifically, assessment strategies are needed that identify the controlling variables for disordered gambling and, thus, provide guidance in the selection of treatment and prevention strategies. This study sought to develop a functional analysis for gambling by utilizing a simulated gambling environment in which contextual variables hypothesized to be causally linked to disordered gambling could be systematically manipulated. Seven experienced gamblers participated in the multi-element, single-subject experimental study. Participants who endorsed at least some problems from …

Why Abstain? Trends In And Origins Of Indifference And Estrangement In The United States, 1968-2012, Christopher R. Keeler

Masters Theses

Abstention rates have remained quite high in the United States for the last several decades. This thesis explores the trends in and origins of the nonvoters from 1968 to 2012 using a statistical model of abstention in presidential elections. The objective is to determine why nonvoters have chosen to abstain and who are they?

Using data from the American National Elections Studies, four groups of nonvoters are identified – voters who are both alienated and indifferent, voters who are neither alienated nor indifference, voters who are only alienated, and voters who are only indifferent. The two groups exclusively analyzed are …

Exploration Of Linguistic And Extra-Linguistic Factors In Stroke Knowledge And Emergency Response: Studies Of Input, Output, And Outcome, Laura L. O. Froeschke

Dissertations

This dissertation is comprised of three studies centered on addressing factors that influence stroke knowledge and decision-making during the acute stroke emergency in both general and Hispanic populations. The first study provided data on patterns of explicit stroke knowledge in a sample of 94 Hispanic subjects. This study assessed relationships between stroke knowledge (Stroke Action Test; STAT; Billings-Gagliardi & Mazor, 2005) and subjects’ typical language use (Short Acculturation Scale for Hispanics; Marín, Sabogal, VanOss Marín, Otero-Sabogal, Pérez-Stable, 1987). No relationship was found between language use (Spanish/English) and stroke symptom knowledge. Contrastingly, STAT scores were found to …

Multi-Level Adjustments In Singing Behavior By A Migratory Songbird In Response To Urbanization, Jacob Job

Dissertations

The spread of high-amplitude anthropogenic noise across natural landscapes is a serious issue for vocally communicating animals. Noise disrupts communication, which has implications for individual fitness and population persistence. In response, animals adjust their vocal signals with increasing noise. As the increase in noise has occurred on a relatively short time scale, evolutionary responses are likely not the primary cause of adjustments. Instead, short-term behavioral adjustments may drive population differences; however, such adjustments are currently not well understood. Moreover, noise is only one characteristic of urbanized landscapes and whether other characteristics, such as highly reverberant surfaces interact with noise to …

Family Resilience And Sojourning Japanese Families In The U.S., Mitsuyo Izumi

Dissertations

This study examined processes of family resilience sojourning Japanese parents reported using while raising children (between the ages of 4 and 8) in the U.S., the relationship between family resilience and child behavior and impact of stressful life events, and predictors of the impact of stressful life events and child behavior. Seventy mothers and 37 fathers from six Japanese educational institutions completed self-report questionnaires. Measures included Japanese translations of the Family Resilience Assessment (Duncan Lane, 2011), Strengths and Difficulties Questionnaire (Goodman, 1997), the Impact of Stressful Life Events Scale (Hasui et al., 2009), the Kansas Marital Satisfaction (Schumm et al., …

Dissertations

This study examined the relative effects of tiered goals, difficult goals, and moderate goals on performance when individuals earned bonus pay for goal achievement. The experimental design was a 3 x 2 mixed factorial design. Participants were 44 undergraduate students performing a computerized data entry task that simulated the job of a medical data entry clerk. For each session, participants were paid a $4 base salary plus bonus pay contingent on goal achievement. Participants were randomly assigned to 1 of 3 groups: a) a multiple, tiered goal level condition, in which participants earned $1 in bonus pay for achieving an …

Emotional Responses To Musical Dissonance In Musicians And Nonmusicians, Rebecca Joan Bumgarner

Masters Theses

The purpose of this project was to investigate the influence of music education on individuals’ subjective and physiological responses to consonant and dissonant excerpts. Participants were categorized as having high experience (HE) or low experience (LE) in music education. Participants listened to 40 randomized excerpts of music, half of which were consonant, the other half dissonant. Electrodermal Activity (EDA) and Facial Electromyography (EMG) data were collected for each participant, as well as self-reports of perceived pleasantness for each excerpt. It was expected that HE participants “learned” dissonance through music education, and therefore would respond more strongly to dissonant excerpts. As …

Assessing The Effectiveness Of A Picture Exchange Communication System On Increasing Manding And Vocal Speech In Identical Twin Adults With Autism, Laura C. Hilton

Dissertations

This study examined the effectiveness of a Picture Exchange Communication System (PECS) on increasing manding (i.e., making requests) and spontaneous vocalizations. Participants were a set of identical twin adult women, both with a diagnosis of autism. The main dependent variable was the number of mands emitted by the participants while utilizing PECS. During each phase of training, participants had to meet a specific criterion before receiving a preferred item. Once the participants met the criterion for each phase of PECS training, a new phase began. Spontaneous vocalizations were tracked during each phase of training to determine if, as previous studies …

Missing Pieces: How Neighborhood Health Context Influences Jail Reentry, Andrew Gregg Verheek

Dissertations

This study explores how neighborhood context influences the odds of reoffending by those released from incarceration at a local jail facility. Using data from four sources, I seek to contribute to the understanding of reentry by including two factors missing from current theoretical and empirical work on inmate recidivism. First, using a social disorganization perspective, I include measures of neighborhood health to gain an understanding of how increased substance abuse, mental health, and physical health issues among neighborhood residents impede the development of social capital and informal control that are crucial to the reduction of recidivism. Additionally, I examine jail …

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 …

Increasing Physical Activity In Young Adults With Autism Spectrum Disorder, Katherine B. Lalonde

Dissertations

Experts recommend that individuals walk 10,000 steps or more per day and doing so has been shown to have several health benefits. Unfortunately, many people fall short of 10,000 steps per day. Exercise levels are characteristically lower in people with Autism Spectrum Disorders (ASD) than in people without ASD. The present study comprised two experiments that used goal setting and reinforcement to increase physical activity in young adults with ASD. The first study employed a multiple-baseline-across-participants design in combination with a reversal design to determine the effects of a treatment package on the number of daily steps taken by young …

Choices Related To Maximizing Quality Of Life At End Of Life, Theresa Lynn

Dissertations

Humans, including those residing in the United States, can live in denial of their own mortality. Because of this, futile care is sometimes provided, often at great monetary expense and for little or no return in terms of quality or length of life. At least two opportunities exist for making choices regarding care at the end of life in the U.S.: completing advance directives and choosing hospice care. This dissertation consists of three studies related to this topic. The first is a quantitative study about advance directives and attitude toward death. The advance directive completion rate among adults in the …

Understandinq Second Generation Southeast Asian Americans' Lived Experience Of Lnterracial Romantic Partnerships With White European Americans, Sophia K. Rath

Dissertations

Scholars and mental health professionals whose work involves interracial romantic partnerships (IRPs) have a responsibility to be sensitive to the racial, ethnic, and psychological diversity that characterizes these relationships. Although a growing body of research exists about IRPs, no study to date has explored how being a second generation U.S.-born Southeast Asia American (SEAA) impacts individuals’ experiences in IRPs with White European Americans (WEAs). The present study employed qualitative, phenomenological methods to explore how second generation SEAAs make meaning of their personal and relational experiences in IRPs with WEAs. Semi-structured in-depth interviews were conducted with 11 participants.

An Evaluation Of The Primary Care Providers’ Perspective Of The Effects Of Moderate Alcohol Consumption On Health, Gisele Tchamba

Dissertations

The complexity of health benefits of moderate alcohol consumption (MAC) is well documented. From the World Health Organization recent report, impact of harm from alcohol consumption was 3.3 million deaths or 5.9 percent of all global deaths (WHO, 2014).

Yet, the benefits of MAC for better health and longer life expectancy compared with abstinence are advocated in numerous studies (Nova, Baccan, Zapatera and Marcos, 2012). However, the nature of alcohol, its role on human sufferings has generated disagreements in the scientific community. Analysis of the results of early studies advocating better health for moderate drinkers, reveal discrepancies regarding the influence …

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 …
