Effects Of Talker Variability On Categorization Of Spectrally Degraded Vowels., Emily A. Dickey
College of Arts & Sciences Senior Theses
When a person listens to a context sentence with prominent higher frequencies, the subsequent vowel sound is more likely to be perceived as being of a lower frequency and vice versa. This is a spectral contrast effect (SCE). Recent work has shown that talker variability diminishes these SCEs. They were found to be smaller when 200 sentences were spoken by a different talker each time compared to one talker (Assgari & Stilp, 2015). Cochlear Implant (CI) users’ speech categorization is also influenced by SCEs but are known to struggle with talker discrimination. Here, I tested whether talker variability affected SCEs …

The Effects Of Sex Role Stereotype Endorsement And Work-Family Conflict On Emerging Adult Aspirations, Andrea Fink-Armold
UNLV Theses, Dissertations, Professional Papers, and Capstones
Workplace and household inequality remain prevalent in the United States and sex role (e.g. breadwinner and caregiver) stereotypes affect the roles that individuals seek out. This research used a mixed-methods approach to investigate the effects of sex role stereotypes and expected work-family conflict on the work and family aspirations of emerging adults. A racially diverse sample wrote freely about their future selves for ten minutes then completed measures to evaluate their sex-role stereotype endorsement, expected work-family conflict, and personal preferences for career and family roles. Results indicate that endorsement of stereotypes predicts increased expectations of work-family conflict, for both men …
An Investigation Into The Structure Of Self-Control,

East Tennessee State University
An Investigation Into The Structure Of Self-Control, Parker A. Dreves
Electronic Theses and Dissertations
Self-control has been measured using a variety of methods including self-report measures, cognitive inhibition tasks, delay discounting and delay of gratification tasks, and persistence and willpower tasks. Although these are all theoretically linked to processes involved in self-control, recent evidence has shown that these diverse measurement techniques relate only minimally to one another. Assuming that self-control is a reflective construct, this would indicate that many of these tasks are poor indicators of self-control. The present research challenges the common assumption that self-control is a reflective construct and instead proposes that self-control is a formative construct. Conceptualizing self-control as a formative …

Mathematics Attitudes And Mathematics Performance: Novel Approaches Towards Noncognitive Educational Measurement, Applications To Large-Scale Assessment Data, And Examinations Of Multigroup Invariance, Kalina Gjicali
Dissertations, Theses, and Capstone Projects
Academic performance is predicted by a multitude of demographic, contextual, cognitive, and noncognitive constructs. The noncognitive factors of achievement in mathematics that have previously been explored in depth are study skills, collaborative problem-solving, confidence, self-efficacy, and personality traits (Kyllonen, 2012). Limited applied research has explored the predictive value of noncognitive factors such as attitudes and beliefs in mathematics achievement – even though attitudes towards mathematics are a promising avenue for understanding the variability in mathematics achievement. The current research uses the theory of planned behavior (TPB) to explain high school students’ performance in mathematics in a series of three studies. …
Considerations In S-Χ2: Rest Score Or Summed Score, Priors, And Violations Of Normality,

Considerations In S-Χ2: Rest Score Or Summed Score, Priors, And Violations Of Normality, Christine E. Demars, Derek Sauder
Department of Graduate Psychology - Faculty Scholarship
The S-χ2 item fit index is one of the few item fit indices that appears to maintain accurate Type I error rates. This study explored grouping examinees by the rest score or summed score, prior distributions for the item parameters, and the shape of the ability distribution. Type I error was slightly closer to the nominal level for the total-score S-χ2 for the longest tests, but power was higher for the rest-score S-χ2 in every condition where power was < 1. Prior distributions reduced the proportion of estimates with extreme standard errors but slightly inflated the Type I error rates in some conditions. When the ability distribution was not normally distributed, integrating over an empirically-estimated distribution yielded Type I error rates closer to the nominal value than integrating over a normal distribution.

Restructured Frame-Of-Reference Training Improves Rating Accuracy, Ming-Hong Tsai, Serena Wee, Brandon Koh
Research Collection School of Social Sciences
The use of heuristic judgments is prevalent in organizations and negatively impacts accurate employee assessments. To minimize the negative impact of heuristic judgments (i.e., anchoring and adjustment), we aim to improve rating accuracy by restructuring frame‐of‐reference (FOR) training. We conducted five studies (N = 1,143) using different samples (three including participants with hiring experience), training environments (onsite and online), and rating contexts (evaluations of sales representatives, teachers, contract negotiation specialists, and retail store managers). Across the five studies, the average improvement in rating accuracy was at least twice as large for restructured FOR (vs. control) training as it was for …

A New Paradigm Of Discrimination And Measures Of Latino Linked Fate, Michael Herndon
UNO Student Research and Creative Activity Fair
Linked fate has long been used as a measure of group consciousness and is an important component of group political behavior. Though applying linked fate to Latinos can be complicated because of a widely diverse set of nationalities and historical contexts, Latinos have shown signs of group cohesion under certain circumstances. Despite this, there is still a sizable gap exploring the theory of linked fate as it pertains to Latinos. Furthermore, there is a near-absence of literature that critically dissects the roles of different kinds of discrimination as they pertain to perceptions of linked fate amongst Latinos. There are distinct …

Contextually Modulated Avoidance Behavior In Rats Post-Pavlovian Extinction, Lauren Branigan
Theses and Dissertations
The following study sought to examine the psychological substrates of renewal (e.g.., context dependent extinction processes) for conditioned avoidance behaviors in rats. Using signaled active avoidance conditioning, rats acquired two-way shuttle responding, to two different auditory stimuli. These behaviors were then extinguished through exposure to the auditory stimuli where shuttling behavior was now without consequence. Subjects were then tested for renewal of avoidance in three distinct renewal sequences (e.g., ABA vs ABB, AAB vs AAA, and ABC vs ABB) in three separate groups of rats. It was found that subjects showed more responding to a stimulus presented outside of its …

Integration And Segmentation Conflict During Ensemble Coding Of Aspect Ratio, Elric Matthew Elias
Electronic Theses and Dissertations
The visual system often integrates information that "goes together". Once information has been integrated, summary information (e.g., average emotion or average size) can be extracted; this occurs during ensemble coding. Integration thus allows for fast and efficient generalizations about sets to be made. In contrast, the visual system sometimes segments input that does not go together. For example, the perception of objects can be exaggerated away from natural category boundaries (e.g., a perfect circle is a category boundary; it is neither "flat" nor "tall"). Segmentation allows the visual system to make quick categorical distinctions. Much of the time, integration …
Individual Adjustment As A Predictor Of Improvements In Romantic Relationship Quality From Adolescence To Adulthood,

University of Denver
Individual Adjustment As A Predictor Of Improvements In Romantic Relationship Quality From Adolescence To Adulthood, Jamie Novak Shoop
Electronic Theses and Dissertations
Previous work suggests that individuals who experience a poor quality romantic relationship during adolescence are at heightened risk of experiencing poor quality romantic relationships in adulthood. However, this literature has not yet identified factors that may predict which individuals will go on to experience improved romantic relationship quality in adulthood, despite having experienced a poor quality romantic relationship during adolescence. The goal of the current study was to examine whether adolescents' psychosocial adjustment (internalizing and externalizing symptoms, substance use, and self-esteem) predicted improvements in the quality of their subsequent romantic relationships. Data were drawn from a community sample of 200 …

Stress, Social Support, And Mindfulness In Parents Of Children With Neurodevelopmental Deficits: A Quantitative Analysis, Branden D. Syrotchen
Walden Dissertations and Doctoral Studies
Parenting children with neurodevelopmental deficits (NDDs) is very stressful, more so than the parenting of typically developing children. There is considerable research on the topic of chronic stress experienced by caregivers; however, less is understood of parental stress experienced when raising children with NDDs. The purpose of this study was to examine how parental traits and habits, in the forms of mindfulness and social support levels, affect this cohort's general stress levels. The study was guided by Self-Determination Theory, which explored how parental acts could be classified along a continuum of being intrinsically or extrinsically derived. A convenience sample of …

Parental Alienation As A Predictor Of Adult Marital And Romantic Relationship Quality, Leslie Elizabeth Krill-Reiter
Walden Dissertations and Doctoral Studies
Divorce rates have consistently risen over the past several decades along with the subsequent increase in parental alienation occurring after the breakup of the family. Parental alienation has long-term negative effects on children who have experienced it, including mental health issues, increased risk of substance abuse, lower levels of self-sufficiency, and decreased physical health. The purpose of this quantitative, nonexperimental study was to determine whether alienation from a parent during childhood impacts the quality of adult romantic and marital relationships of the children when they become adults. The Bowen family systems theory and theory of attachment were used as the …

Spousal Caregivers' Challenges When Caring For Their Loved Ones Battling Alzheimer's Disease, Patricia A. Light
Walden Dissertations and Doctoral Studies
In the United States, the occurrence of Alzheimer's dementia is growing. This chronic illness is highly prevalent in the elderly population. Studies have advised that the elderly population is primarily affected by this chronic illness as age progresses. Aging may lead to mental or physical deterioration. This chronic illness can be extremely challenging for the spousal caregivers involved and the challenging decisions that must be made. There remains a crucial gap in the literature concerning the challenges experienced by spousal caregivers and how they cope with these factors daily. Specifically, there are no studies exploring the perceptions of spousal caregivers …

Subjective Sleep Quality Of Isolated Sleep Paralysis: Fear Parameters And Psychosocial Correlates, Yudyahn Kushkituah
Walden Dissertations and Doctoral Studies
The bidirectional link between insufficient sleep and the distress related to a parasomnia known as isolated sleep paralysis (ISP) might lead to chronic health effects. The impact of fear-ridden hallucinations related to this REM sleep disorder can be both distressful and embarrassing for individuals often resulting in a reticence to seek help. This quantitative study was guided by a biopsychosocial approach with an integrated theoretical framework. One aim of the study was to determine if fear parameters of ISP (low and high) differ when considering psychosocial factors and sleep quality, based on the Dysfunctional Beliefs and Attitudes About Sleep Scale, …

Cultural Distance, Acculturative Stress, Social Support, And Psychological Adaptation Of International Students, Ariel Mitchell Ladum
Walden Dissertations and Doctoral Studies
International students experience stress and adaptation difficulties as they study in a new culture. This study examined how cultural distance, acculturative stress, and social support interacted to influence positive and negative emotional responses among international students in the northern part of Cyprus. Acculturation models and the stress-buffering hypothesis served as theoretical frameworks. The 2 research questions involved understanding whether international students experienced more negative emotional responses compared to students from the home culture and whether social support moderated acculturative stress and reactions to being in the northern part of Cyprus. An analysis of variance (ANOVA) was used to examine differences …

Positive Experiences Among Dui Offenders In Court-Mandated Substance Abuse Treatment, Katarzyna Blanka Pilewicz
Walden Dissertations and Doctoral Studies
Driving under the influence (DUI) of alcohol and other drugs puts communities' and individuals' safety at tremendous risk. The excessive use of alcohol, illicit drugs, and/or some prescribed medications causes cognitive impairment and the physical incapability of operating a vehicle. The court system penalizes drunken driving behaviors by placing DUI offenders in a variety of mandated interventions to minimize the risk of reoffense. The purpose of this phenomenological study was to explore DUI offenders' positive experiences and perceptions derived from DUI programs and how they impacted well-being and commitment to positive change using Seligman's well-being theory as a conceptual framework. …

The Impact Of Critical Incident Team Training On Arrest And Diversion Rates, Richard Wayne Foss
Walden Dissertations and Doctoral Studies
The Critical Incident Team (CIT) training program equips police officers with knowledge regarding mental illness and practical skills for effectively interacting with a mentally ill suspect. In addition to improving officer and suspect safety by decreasing the number of violent encounters between police and the mentally ill, CIT goals include reducing the number of mentally ill individuals who are arrested and providing them with assistance through community resources. However, there is a lack of empirical research on whether CIT training decreases arrest rates and increases diversion rates for mentally ill subjects. The purpose of this quantitative study was to measure …

Staff And Family Perspectives Regarding Person Centered Care For Adults With Intellectual Disability, Tasrina Khan
Walden Dissertations and Doctoral Studies
Individuals with intellectual disabilities often require additional support in performing daily activities as compared to individuals without intellectual disabilities. New York's Office for Developmental Disabilities developed the eight hallmarks of person centered planning to help individuals with intellectual disabilities understand the options available to them regarding care and support and to advocate for themselves and their rights. Researchers have yet to articulate how guardians and professional care providers of individuals with intellectual disabilities experience person centered planning in day habilitation. Thus, using a qualitative phenomenological approach, 5 direct care staff and 5 guardians of individuals with intellectual disabilities were interviewed …
