Multipurpose Map Designs For Gps Surface-Vehicle Navigation: Spatial Knowledge And Advisory Functions, Caitlan A. Rizzardo

Browse all Theses and Dissertations

Current car navigation systems primarily utilize track-up maps with spatial turn arrows, which facilitate turn decision-making but do not facilitate acquisition of spatial knowledge of the region. North-up maps do facilitate acquisition of regional spatial knowledge, however, these displays sometimes have arrows heading in directions misaligned with a driver's forward view, such as when the car is heading south. Drivers have difficulty making turn decisions in these misaligned maps because of stimulus-response reversals (Chan and Chan, 2005; Levine, 1982; Levine, Marchon and Hanley, 1984; Montello, 2010). A new display was designed using a fixed orientation north-up map and added a …

Developing A Word Fragment Completion Task For Measuring Trait Aggression, Steven Khazon

Browse all Theses and Dissertations

The goal of this paper was to develop a test that uses the implicit processing style to assess aggression. This paper begins by reviewing current aggression theories and how aggression is assessed. Next it discusses the implicit and explicit processing styles and how scholars have used these methods of information processing to create psychological assessments. Afterwards, it presents a new indirect test of trait aggression that is based on the word fragment completion task and attempts to evaluate its validity in three experiments. In Study 1, psychometric methods are used to derive a 9-item trait aggression scale and initial support …

The Role Of Deliberate Behavior In Expert Performance: The Acquisition Of Information Gathering Strategy In The Context Of Emergency Medicine, Frank Eric Robinson

Browse all Theses and Dissertations

Effective performance in dynamic domains requires experts to assess problems and implement solutions within the constraints of their work system, but these processes are not well accounted for in the expertise literature. I observed resident and attending emergency physicians to determine the behaviors that distinguish doctors as they manage patients and what contextual variables may affect these behaviors. Factor analyses revealed three types of behavior: goal establishment behavior, goal enactment behavior, and acknowledging uncertainty. Multilevel analyses indicated that doctors' experience and both the local and global context of care impact these behaviors. More experienced doctors appear to be more sensitive …

Sound Localization In Multisource Environments: The Role Of Stimulus Onset Asynchrony And Spatial Uncertainty, Brian David Simpson

Browse all Theses and Dissertations

Several studies have shown that detection of a target in a concurrent noise masker improves when the masker onset occurs prior to that of the target (see, e.g., Zwicker, 1965; McFadden, 1966; Yost, 1985). Recent research indicates that this "masker fringe" (i.e., the portion of the masker occurring prior to the target onset) also facilitates sound localization in noise (Simpson, Gilkey, Brungart, Iyer, & Romigh, 2009a; Simpson, Gilkey, Brungart, Iyer, & Hamil, 2009b). However, these studies do not provide a clear indication of what information listeners are exploiting to obtain this improved localization performance. This dissertation was designed to determine …

Replacing Indirect Manual Assistive Solutions With Hands-Free, Direct Selection, James W. Leonard Jr.

Browse all Theses and Dissertations

Case study BK is a teenage male who suffers from severe cerebral palsy, making communication very difficult using his current assistive technology. His performance with a manual switch was compared to a hands-free system for computer interaction (Cyberlink Brainfingers/ NIA). BK uses a switch scanning menu, which steps through predetermined options till he chooses the current option being read aloud by pressing a button. A yes/no menu was used for the switch scanning interface for both manual and hands free conditions, as well as the point and click condition. In both hands-free conditions, BK was as fast and accurate as …

Cognitively Sensitive User Interface For Command And Control Applications, Michael James Findler

Browse all Theses and Dissertations

While there are broad guidelines for display or user interface design, creating effective human-computer interfaces for complex, dynamic systems control is challenging. Ad hoc approaches which consider the human as an afterthought are limiting. This research proposed a systematic approach to human / computer interface design that focuses on both the semantic and syntactic aspects of display design in the context of human-in-the-loop supervisory control of intelligent, autonomous multi-agent simulated unmanned aerial vehicles (UAVs). A systematic way to understand what needs to be displayed, how it should be displayed, and how the integrated system needs to be assessed is outlined …

Modern Arab Discourse And Democracy: An Epistemological Critique, Ali Saeed Abd

Browse all Theses and Dissertations

Nearly two centuries have elapsed since the early 19th century modern Arab nahda. In contemporary Arab-Muslim accounts, there can be no downplaying the fact that after nearly two centuries, the Arab nahda has faltered at achieving its desired objectives. If so, what explains its faltering? Numerous well-read explanations on this bulk in Arab and Western literature; however, I argue that the most important factor behind the faltering of Arab nahda to date is the faulty form of Arab rationality dominating nahda discourse since its inception: ahistoricity. The entirety of Arab discourse treats the past as ahistorical and sacral to be …

Reconstructing Autism: A Phenomenological Study Of The Relationship Between Parents And Their Children Diagnosed With An Autism Spectrum Disorder, Laura Elizabeth Solomon

Browse all Theses and Dissertations

This study aims to serve as a deconstruction of the experience of parenting a child with an autism spectrum disorder (ASD). The increasing number of families with children affected by ASDs has led to many questions about the impact of ASDs on the family unit; however, the voice of parents is sorely missing in the extant research. The history of ASDs and disability in general continues to impact the ways families, society, and professionals treat families affected by ASDs, and particularly the ways they view and value the parent-child relationship. Six mothers of children with ASDs were interviewed about their …

Children's Grief Resources: A Website For Children Grieving The Loss Of A Parent And Their Caregivers, Jami L. Pfirrman

Browse all Theses and Dissertations

The death of a parent can represent one of the most devastating life experiences for children. It is an experience that disrupts a developmental path. It is also a crisis that families and communities must address in order to help a grieving child cope and develop resilience. Currently, there are few mental health resources available for parentally bereaved children. Literature on bereavement following the death of a parent suggests that children may experience long-term negative psychological consequences from the loss. However, the literature also notes that with appropriate support, access to resources, and opportunities to express their grief and build …

Mindfulness For The Millennial Generation: A Clinician's Handbook For College Counseling Centers, Shaznin Percy Daruwalla

Browse all Theses and Dissertations

The current generation of college students, the Millennials (Howe & Strauss, 2000, 2007) lead highly pressured and achievement-oriented lives. Along with generational changes, change is occurring on university campuses, especially in terms of mental health demographics. There is an increase in the severity of presenting concerns reported by students as seen at counseling centers (Gallagher, 2008), and more students with existing mental health diagnoses are seeking college admissions (Gallagher, 2009). Changes in the current college student generation and socio-cultural changes underscore the need for an effective stress-reduction program for university students. Mindfulness-based interventions have received attention from researchers and clinicians. …

Parent-Child Interaction Therapy (Pcit) & Maternal Depression: A Proposal For The Application Of Pcit With Mothers Who Are Depressed And Their Children, Seema Jacob

Browse all Theses and Dissertations

Maternal depression is often a prevalent disorder in society, which has far reaching effects on the psychological well being of both the mother as well as her child(ren). Research has indicated that maternal depression impacts the parenting skills of a woman and thereby puts her children at risk for maladaptive ways of behaving. Children of mothers who are depressed are at a higher risk of developing externalizing and internalizing problems. Many of the empirically supported treatments for depression focus on the individual aspects of the person, without considering the roles and stress of being a parent. Many treatments for children …

Sexual Satisfaction In Women With Physical Disabilities: Results Of An Online Survey, Jessica Rose Heschel

Browse all Theses and Dissertations

The study of sexual satisfaction and pleasure in Women with Disabilities (WwD) represents a significant gap in the current literature. The present study, using a Participatory Action Research (PAR) approach, attempted to explore several areas of the sexual satisfaction of WwD. An internet-based survey was used to gather information in five specific areas: the messages WwD had received about sexuality and disability, their personal feelings about sexuality and disability, the specific elements that contribute to their sexual satisfaction, the amount of useful education and information they had received from mental and physical healthcare providers regarding their sexuality as WwD, and …

Multicultural Group Screening Form (Mgsf): Development Of A Pre-Group Screening Form For Use With Diverse Groups At University Counseling Centers, Taronish H. Irani

Browse all Theses and Dissertations

To date, no instrument has been developed that specifically assesses multicultural issues within the context of group work. Rather, such issues are based to a large extent on clinician's judgment (Corey & Corey 1992; Jennings & Anderson, 1997; Riva, Lippert, & Tackett, 2000). The purpose of this study was to develop an instrument (i.e., the Multicultural Group Screening Form, MGSF) designed to address this void in the literature. Such a tool provides a basis for future studies on the multicultural factors that could impact the group process and outcome. Among the group literature reviewed, DeLucia-Waack's and Donigian's (2004) discussion on …

Pre-Group Preparation In College Counseling Centers: Through The Use Of An Audio-Visual Aid, Darius Dexter Campinha-Bacote

Browse all Theses and Dissertations

The current dissertation articulates the importance of pre-group preparation, specifically in college counseling centers. The dissertation examines relevant research related to the need for pre-group preparation, as well as the various methods in which information can be delivered to clients. The researcher found that although there are several effective ways to prepare clients for group therapy, an underutilized, efficient, and cost effective way to deliver this information is through the use of an audiovisual aid (Acosta, Yamamoto, Evans & Skilbeck, 2006; D'Augelli & Chinsky, 1974; Egan, 1970; Hoehn-Saric, 1964; Martin & Shewmaker, 1962; Orne and Wender, 1968; Sloane, Cristol, Pepernik, …

The Impact Of Non-Reading Language Performance On The Estimation Of Premorbid Iq Among Normal Elderly Individuals, Abraham Maniparambil-Eapen

Browse all Theses and Dissertations

The influence of non-reading language ability was studied in the context of estimating premorbid IQ among normal elderly individuals. Non-reading language performance was measured by the Controlled Oral Word Association (COWA) Test and the Animal Naming (AN) Test. Non-reading language disturbances were divided into three levels (i.e., no disturbance on COWA and AN, either COWA or AN disturbance, and both COWA and AN disturbances). Intellectual ability was primarily measured by the Wechsler Abbreviated Scale of Intelligence (WASI). Additionally, reading measures such as the New Adult Reading Test- Revised (NART-R) and the Wide Range Achievement Test- Fourth Edition (WRAT-4) Word Reading …

Growth Attenuation, Sterilization, And Cochlear Implants: Ethical, Legal And Social Themes, Jenna Nicole Mercadante

Browse all Theses and Dissertations

Individuals with disabilities have been the subject of invasive medical procedures throughout history, violating their bodily rights and integrity. Because of a history of abuse, medical procedures performed on individuals with disabilities, especially those who cannot consent, require close scrutiny and analysis. This paper explores three controversial medical procedures performed on individuals with disabilities, which include sterilization, cochlear implants, and growth attenuation. Embedded in each medical procedure mentioned above are social, legal, ethical, and psychological variables that influenced the emergence of each procedure and the receptiveness of society. This project explores each of these variables in detail as it relates …

Deaf Group Identification And Sexual Esteem, Anne M. Willis

Browse all Theses and Dissertations

The purpose of this study was to examine sexuality in persons who are deaf. Specifically, it examined group identification and sexual esteem, sexual satisfaction, and sexual preoccupation. Deafness was viewed in this study as not only a level of hearing loss, but as a source of identity and culture. While varying levels of group identification are well defined in the literature, it is unclear as to how this impacts the individual's experience. Analysis of the current sample (N = 68) suggested that there was a slight difference in sexual esteem between subjects who identified as Bicultural, Immersed, Marginalized, and Hearing. …

Kids Able To Fight Stress Everyday (Kafse): A Stress-Management Program For Children With Medical Diagnoses, Aimee N. Townsend

Browse all Theses and Dissertations

It is estimated that 10-30% of children in the United States are currently diagnosed with a chronic illness. Due to recent medical advances and increased knowledge of disease maintenance, many of these children will live into adulthood. In addition to physical symptoms of chronic illness, recent attention has been drawn to the psychological effects of chronic illness on children and adolescents. Illustrating this fact, researchers have recently called for increased research on children with chronic illness and disease. One psychological symptom that may be considered is that of stress and its effects on this special population. As a result of …

Predicting Conflict In Group Psychotherapy: A Model Integrating Interpersonal And Group-As-A-Whole Theories, Kyle G. Barry

Browse all Theses and Dissertations

Literature on group dynamics has typically focused on six content areas; (1) cohesion and group identification, (2) attributions and perceptions in group, (3) leadership and performance in groups, (4) power and relationships among group members, (5) knowledge and cognitive process in groups, (6) group psychotherapy (Kivlighan and Miles, 2007). While this literature base has built sophisticated theories, these theories tend to be disconnected and lack applicability to clinical practice. This dissertation will integrate interpersonal and group-as-a-whole theories in order to predict the probable dynamic interactions that theoretically occur as individuals move through conflict within group psychotherapy. Recommended interventions are included …

The Power To Promote Justice Program: A Train-The-Trainer Model For The Development Of Culturally Competent Teaching Practices Among Secondary Educators, Patrece Gabrielle Hairston

Browse all Theses and Dissertations

As the United States population becomes increasingly diverse, the need for multicultural training is greater than ever. Due to this tremendous shift in societal demographics, today's classrooms require teachers to educate students varying in culture, language, abilities, and many other characteristics. The Power to Promote Justice program is intended to provide educators with in-depth training in multicultural education. There is evidence to suggest that many teacher education programs provide minimal training in this area, leaving teachers ill equipped to manage the difficulties associated with working with diverse populations. The Power to Promote Justice Program is a five-session train-the-trainer program that …

Browse all Theses and Dissertations

This study utilized a Participatory Action Research (PAR) design to modify a measure that examines the sexual knowledge, experiences, and needs of people with physical disabilities. Participants (N = 23) were college students with physical disabilities that were registered for disability services at a medium sized Midwestern university. Participants completed a secure online survey that allowed them to provide feedback on the utility of the questionnaire. Preliminary data also were gathered and reviewed. Results revealed both convergence and divergence with the existing literature. Limitations, research and clinical implications, and future directions were also explored.

Animal-Assisted Therapy: An Adjunctive Intervention For Reducing Depression And Anxiety In Female College Students With Physical Disabilities And Guidelines For Implementation Into Psychotherapy Practice And Research, Erin Nicole Armour

Browse all Theses and Dissertations

The existing literature has indicated that women with physical disabilities are at greater risk for depression and anxiety compared to men with similar limitations and their able-bodied counterparts (Nosek & Hughes, 2003). In addition to this, female college students with physical disabilities are at greater risk for attrition than able-bodied female college students (Gmelch, 1998). This dissertation discusses the benefits and criticisms of animal-assisted therapy as an adjunctive intervention for depression and anxiety in this population. It also provides guidelines for implementing it into psychotherapy practice and research.

A Solution-Focused Group Treatment Approach For Individuals Maladaptively Expressing Anger, Kimberly Marie Brzezowski

Browse all Theses and Dissertations

This dissertation describes a proposed protocol for a brief solution-focused group treatment model for treating "expressed externalized anger". Such an approach postulates that positive and lasting change can come about in a relatively brief period of time by using a solution-focused rather than a deficits-focused approach. Without minimizing or diminishing the negative and detrimental consequences of maladaptive anger expression, a solution-focused approach aims at using an empowering approach to hold group members responsible for recognizing and utilizing solutions to their difficulties in appropriately managing their anger. This proposed protocol includes a complete solution-focused treatment approach with a stage by stage …

Employee Age Differences In Formal Performance Feedback Reactions: Examining The Effects Of Perceived Valence, Content, And Delivery, Gabriela Burlacu

Dissertations and Theses

As the nature of work is rapidly changing, organizations in developed nations all over the world are experiencing shifts in the age composition of their workforces. These changes, which include an aging workforce that is becoming increasingly age-diverse, indicate that organizational researchers and practitioners need to be better aware of how age differences manifest themselves in the workplace and what implications this has for effective employee management. In the current study it is proposed that employees of different ages react differently to various elements of a formal performance feedback event. Specifically, Carstensen's developmental Socio-emotional Selectivity Theory is used as a …
