The Other Race Effect : The Role Of Experience And Social Attiudes On Face Recognition, Emily Wheat

Master's Theses

The ORE is phenomenon whereby recognition for own race faces is better than recognition of other race faces. This study examines how non-perceptual factors—social context, attitudes, and experience—impact the ORE. Participants from three different racial groups (Caucasian, Black, Asian) completed a face recognition task screening faces for status-specific targets (baseline, perpetrator, victim), self-report measures of explicit bias and experience with members from other races and a measure of implicit bias. Results indicated that non-perceptual factors impact the ORE. Specifically, Caucasian participants revealed a reduced ORE for other race perpetrators in comparison to victims. Black participants revealed a reduced ORE for …

Shared Features And Similarity : Implications For Category Specificity And Normal Recognition, Daniel Kinka

Master's Theses

Patients with category-specific visual agnosia (CSVA) often exhibit a disproportionate difficulty recognizing objects from biological categories due (in part) to the fact that exemplars from biological categories tend to be visually and conceptually more similar. Similarity is often conceived of as a pairwise property (i.e., in terms of distance in a psychological space matrix), but may be more accurately conceived of as a setwise property (i.e., in terms of shared features). The purpose of this study is to examine the effect of shared features on similarity in normal observers, while controlling for distance in structural space. Behavioral and electrophysiological results …

Do We Know What We Know? Self- Assessment Across The Lifespan, Courtney Clare Lee

Master's Theses

Self-knowledge can play a critical role in navigating physical, cognitive, and social changes in late life. To protect and preserve one's sense of self against these changes, individuals may engage in self-enhancing and self-serving biases in areas important to self-esteem. The importance attached to these areas may change with age, and self-knowledge of these psychological processes may vary with age. We investigated self-enhancing biases and metacognitive awareness of abilities in adulthood. Participants ranging in age from 20 to 80 completed a series of tests assessing the better than average effect across a variety of age-relevant domains as well as objective …

Why Does This Always Happen To Us? An Examination Of Co-Rumination In The Same Sex Friendships Of Emerging Adults, Teresa Michelle Preddy

Master's Theses

Co-rumination, which has been defined as a passive, repetitive form of problem discussion, has been linked to both benefits in terms of positive friendship quality and maladaptive outcomes such as internalizing distress. This study explored the trade-offs associated with co-rumination in emerging adult same-sex friendships both concurrently and longitudinally through the use of self-report questionnaires. Co-rumination was associated with concurrent positive friendship quality. Additionally, co-rumination partially mediated the link between gender and positive friendship quality, and was a marginal predictor of increases in positive friendship quality over time. Although co-rumination was associated with depression, co-rumination did not predict depressive symptoms …

Neural Replay : A Possible Mechanism For Differing Rehersal Strategies Across Parity, Cassie Brooke Jones

Master's Theses

All mammalian females undergo behavioral and neurological changes during pregnancy and motherhood. Many of these changes lead to an enhanced ability to be an effective mother including: increased memory, foraging behaviors, and boldness. Here, we examined the differences in rehearsal strategies between mother and virgin rats. Stops made by rats when exploring their environment have been found to result in reverse replay activity in the hippocampus (Foster & Wilson, 2006). Reverse replay is sequential replay that occurs in the hippocampus immediately after a spatial experience; this replay/activation is in reversed order of the initial spatial episode (Foster & Wilson, 2006). …

The 9/11 Victim Compensation Fund : A Case Study, Mary Kathleen Gorman

Master's Theses

The 9/11 Victim Compensation Fund was the largest victim compensation fund in U.S. history, disseminating more than $7B federal tax monies directly to survivors, victims and their respective families following the terrorist attacks of that day. This represented an unprecedented effort on the part of the U.S. government to fully fund terrorism victim compensation within a no-fault framework intended, first and foremost, to protect the airline industry from potential economic ruin. But in so doing, the Fund compromised legal, ethical, economic and sociological principles on which victim compensation had been based since the inception of government. This interdisciplinary exploratory case …

Looking Into The Mind Of The Mother : Pup Exposure And Reactivation Of Maternal Circuits, Tricia Lauren Norkunas

Master's Theses

The female rat, among other species, undergoes a fundamental brain re-modeling as a consequence of experiencing the normal and natural events of pregnancy and offspring stimulation. Compelling data show that maternal experiences produce neurobiological modifications in the female leading to specific maternal behaviors, affective states, and the basic underlying female neurobiology necessary to raise viable offspring. This study aims to evaluate the number, quality and selective activation of neurons that develop during the maternal experience. The study showed a trend toward supporting the hypothesis that a “maternal-circuit” is formed through the proliferation of neurons during late-motherhood and lactation, and is …

A Suggested Model For Emergency Medical System Response During An Outbreak Of Human Pandemic Influenza, Ellen A. Black

Master's Theses

Predictions on infection rates for a possible outbreak of human pandemic influenza have officials in Public Health, Epidemiology, Public Safety, and other organizations developing plans on the federal, state, and local levels. These plans are outlining prevention, preparedness, and response during an outbreak, stressing interagency collaboration and contingencies for significant employee absenteeism rates for extended periods of time. However, Emergency Medical Service (EMS) providers will likely face a marked increase for calls for service to the community; and may be forced to provide service with a diminished workforce and additional duties not traditionally performed by their personnel. This Thesis examines …

Are We All Together? : A Study Of Evacuation And Sheltering Of Public Safety Special Needs Populations In The Commonwealth Of Virginia, Anna M. Mcray

Master's Theses

Events thousands of miles away from Virginia have led to enhancements of the existing evacuation and emergency sheltering planning, highlighting the need to consider more than traditional special needs populations. Updated state-level plans specifically address the medical needs of evacuation populations. Pets were taken into consideration and inclusion of dogs, cats, and birds in traditional sheltering planning has begun. Planning began to address those with social needs such as low-income families who may not be able to evacuate until the final hours of an active evacuation. It became clear that there were specific populations that had not been included in …

Local Law Enforcement's Initial Role In Response To A Radiological Dispersion Device Attack, Andrew Robert Hoehl

Master's Theses

Today the potential exists for a terrorist organization to use a Radiological Dispersion Device or a dirty bomb within the United States. The results of such an attack could be catastrophic to the affected population. The response by law enforcement must be calculated and planned.

To properly analyze the law enforcement's role in a radioactive incident a qualitative approach was taken. A determination must be made prior to an attack to discern what kind of training will be necessary, what equipment will be required, and what response procedures need to be in place to ensure a safe and efficient response. …

The Role Of Phonological Similarity In Constructing A Developing Lexicon, Lin Li

Master's Theses

The implicational hierarchy of phonological feature development has proposed that children acquire native phonemic inventory in a systematic way, from the least articulatory-effort-required phonemes to most demanding ones. On the phonemic inventory level, the hierarchy suggests that perceptual features bearing by oral stops /p/, /b/, /t/, /d/, /k/, /g/ would appear ahead of perceptual features bearing by fricatives, affricatives and liquids ... while nasals stops ... would emerge in the middle. With the help of age-of-acquisition index and a phonemic change schema, the distributions of 489 phonological neighbors have been examined against the data from MacArthur Communicative Development Inventory to …

Attentive Mothers Versus Minimally Invested/Neglectful Mothers : The Development Of New Neurons In The Hippocampus Specifically Activated By Foster Pup Exposure, Danielle Christina Worthington Stoneman

Master's Theses

As pregnancy progresses, the female is transformed from an animal that actively avoids pup-related cues (Kinsley, 1994) to one highly motivated to build nests, and retrieve, group, groom, and crouch over a set of pups. In the vast majority of events, motherhood progresses normally; in a striking subset, however, it does not. This study seeks to evaluate neurological differences in the dentate gyrus between primiparous females that respond maternally and those that do not when exposed to foster pups. It was hypothesized that the attentive mothers which perform the expected maternal behaviors have a different number of triple labeled BrdU(measuring …

Using Internet Simulation Games To Train Prehospital Providers For Mass Casualty Response, Meredith L. Moss

Master's Theses

During a disaster emergency medical services (EMS) plays a critical role in supporting mass casualty response. However, the processes and procedures used in a disaster are different than those which the prehospital providers encounter during routine emergency response. With limited time and resources, new approaches to training should be considered. This thesis presents research on EMS training, disaster response, distance learning, and instructional technology. Survey and interview results are analyzed providing a foundation for the development of a proposed software model using Internet simulation games to train prehospital providers for mass casualty response.

The Effects Of Target Age And Perceived Death Responsibility On Posthumous Impression Formations, Jenny Rebekah Heilborn

Master's Theses

Death positivity biases and posthumous evaluations are considered a universal normative social phenomenon which influences social judgments of the dead; we postulate that these individual biases are mediated by both sympathy and fear of mortality, or the belief in a just world. Study 1 postulated that sympathy mediates such positivity biases when target responsibility for cause of death is manipulated. We hypothesized the mediation of the just world violation on posthumous evaluatory measures when age at the time of death was manipulated in Study 2. Although results were inconclusive for both studies, alternate hypotheses and boundary conditions of death positivity …

Motherhood, Memory And Aging : Object Recognition Performance, Julia Margaret Friedenberg

Master's Theses

Reproductively experienced female rats have been shown to have attenuated stress responses, improved visual systems, and better memory and learning. This study sought to extend those findings by comparing aged reproductively experienced and aged virgin female rats on an object recognition task, as well as comparing levels of corticosterone and 17p-estradiol and neural activation. Multiparous (MP, 2 reproductive experiences) females performed better on the task and demonstrated quicker habituation to the task than nulliparous (NP, no reproductive experiences) females. No hormonal or neural activation differences were found. The present study contributes to the growing research areas of reproductive experience and …

Automatic Spatial Processing Of Threatening And Positive Information In Participants With High And Low Levels Of Trait Anxiety, Ryan W. Hansen

Master's Theses

The study sought to investigate potential differences in automatic spatial processing of threatening and positive information in anxious and non-anxious individuals. Participants evaluated threatening and positive words and pictures in a memory task in which the stimuli's varying spatial position was incidental to the task. Participants demonstrated increased accuracy with threatening stimuli, and a decreased accuracy when the word location varied between initial presentation and test. The results did not provide evidence that threatening stimuli were associated with an increased degree of spatial processing, or that this relationship would be influenced by trait anxiety.

Intricacies Of Development : The Impact Of Maternal Experience And Isolation On The Social Development Of Juvenile Male Rats, Lillian Maria Christon

Master's Theses

Reproductive experience induces changes in females. Parity-related differences in maternal treatment of offspring can induce enduring changes in offspring. The relationships between maternal experience, early social isolation, and development were explored in rodents in this experiment. Male rats were weaned from multiparous (MP) and primiparous (PP) mothers and placed into isolation or social housing for four weeks. They were then observed in a social-interaction test. Social behavior and neural oxytocin and vasopressin were assessed post-testing, while corticosterone levels were measured across the four weeks. Weaning was extremely stressful for all offspring. PP- and MP-raised pups exhibited differences in social behavior, …

Early Vocabulary Development In English, Mandarin, And Cantonese : A Cross-Linguistic Study Based On Childes, Shuxia Liu

Master's Theses

Early language development is an exciting topic in the field of child language acquisition. Only a limited amount of cross-linguistic studies has attempted to investigate the similarities and differences in child language development across different languages. In this thesis, I present a study based on English, Mandarin and Cantonese corpora extracted from the Child Language Data Exchange System (CHILDES, MacWhinney, 2000). I investigated the lexical compositions of certain lexical categories (nouns, verbs, and adjectives) in children and their caregivers’ vocabularies across eight different children age groups ranging from 13 to 60 months. ANOVA, frequency analysis, and cluster analysis were used …

Universal Disaster Impact Scale, Brian James Evans

Master's Theses

When disasters occur affecting multiple communities differently, can a determination be made as to which community is in need of financial or humanitarian aid the most? This study proposes a universal disaster impact scale that will allow the impacts of a large variety of disasters, including natural and human systems failures, to be measured against one another. The Universal Disaster Impact Scale includes both quantitative and qualitative disaster impact measurements combined with an economic factor for the affected country in an equation which provides a numeric rating for the disaster. The rating is used to measure the level of need …

The Next Generation Of Emergency Management : Proposal For A New Model Of Emergency Operations Center For A Growing Regional Emergency Management System, John D. Eggleston

Master's Theses

The emergency operations center organizational model used by the Charlottesville/Albemarle/University of Virginia (CAUVA) Emergency Management Agency is organized around the various departments that staff the center. The EOC model has been used to coordinate small scale natural disasters and training exercises, but has never been used to coordinate a significant actual event. After-action reports of previous events and exercises have highlighted several functional deficiencies and have led some local and state officials to doubt the model's ability to coordinate a significant event... The research process involved a literature and extant document review which discovered that there were four recognized EOC …

A Study Of The Best Spanish Training Practices For Police Officers, Nicole Marie Otero

Master's Theses

Within the last ten years, the Hispanic population in the United States has grown immensely. This presents a communication problem between the Hispanic communities and the police departments who protect and serve them. This also creates a serious liability issue for police departments. Currently, law enforcement is struggling to adequately train police officers how to speak Spanish. This research examines ways for Chesterfield and Henrico County Police Departments to develop the Spanish-speaking skills of their current police officers. This research further provides details of possible costs to provide adequate Spanish-speaking training to the police officers in both counties. The data …

Generational Competence And Retention : A Study Of Different Generations In Law Enforcement And How These Differences Impact Retention In The Chesterfield County Police Department, Gary Scott Edwards

Master's Theses

There are currently four distinct generations in today's workforce (Veterans, Baby Boomers, Generation X, and Millennials). This presents unique challenges for employers since each of these generations is affected and shaped by different events in their lives, which define the values they bring to work. These differences can be increasingly difficult to manage and may lead to conflicts. Significant research has been conducted in this area, but little has focused on public sector employees, specifically sworn law enforcement officers. This research examines whether generational differences observed in society as a whole are the same as those differences found in law …

Shrines And Prayers: Two Missing Elements Of Comprehensive Mass Fatality, Rhonda Keyes Pleasants

Master's Theses

As a Licensed Funeral Service Provider, I am aware of the special issues which surround mass fatalities. A study of numerous mass fatality plans yielded identification of two missing elements from most plans which are critical to mass fatality management. The first missing element is ritual used in the respectful treatment of the dead. The second missing element is religious precepts regarding caring for and final disposition of the dead based upon the particular belief system of the deceased, their family, surrounding community, and culture. Specific qualitative methods of research used were a review of the professional literature, identification of …

A Role For Vasopressin And Oxytocin In Parental Behavior Of The Male Sprague-Dawley Rat, Ekaterina V. Karelina

Master's Theses

Paternal behavior, though infrequent in many mammalian species, can be induced under laboratory conditions through manipulation of either hormonal or environmental states. Rodent studies of parental behavior have implicated similarities for males and females in not only the actual behavioral repertoire, but also the brain mechanisms governing the set of behaviors in both sexes. The current project investigated changes in oxytocin and vasopressin in the hypothalamus of paternal male rats. We found that paternal behavior, which was readily induced through sensitization (chronic pup exposure), was significantly correlated with increasing oxytocin and vasopressin immunoreactivity within the paraventricular nucleus. Further, corticosterone levels …

Learned Fear And Reaction To Novel Stimuli: Behavioral And Hormonal Stress Responses In The Maternal Rat, Brandi Nicole Rima

Master's Theses

The present thesis examines the relationship between reproductive experience and the behavioral, neural, and hormonal processes of learned fear in the female rat. Multiple research models indicate that reproductive experience functions to decrease the female's stress response in potentially harmful environments, thus providing her with numerous survival benefits, including decreased fearfulness, increased aggression, and refined hunting skills. Based on existing understandings of maternal experience and unconditioned fear, this study was designed to determine how nulliparous (no reproductive experience, NP), primiparous (one reproductive experience, PP) and multiparous (more than one reproductive experience, MP) rats comparatively respond to a Pavlovian paradigm of …

Conditional Love : A Study Of Situational Differences In Rooting For An Underdog, Sheila Margaret Hindle

Master's Theses

While people tend to root unabashedly for underdogs in the domain of athletics, underdogs do not generally receive the same tremendous support in matters of business. This may occur for a variety of reasons, but of particular interest is the fact that an individual's perception of a situation as both self-relevant and of high consequences may prove detrimental to his or her willingness to support an underdog. Two studies were conducted to explore these hypotheses. Study 1 (N=48) required participants to read a brief scenario depicting a situation of varied self-relevance and consequences, and then select a company to complete …

Predictors Of Breast And Cervical Cancer Screening Among Vietnamese Immigrant Women, Anh B. Nguyen

Master's Theses

Predictors of breast and cervical cancer screening among Vietnamese immigrant women. Anh B. Nguyen, Master of Arts in Psychology, University of Richmond, 2006. Thesis director: Barbara K. Sholley, Ph.D Although practicing preventative healthcare is an important part of a healthy lifestyle, some high-risk populations do not engage in preventative screenings for cancer. Vietnamese American women constitute a high-risk group in gynecological cancers, and it was hypothesized that tenure, acculturation, health insurance, a regular source of care, education, employment status, and marital status would affect rates of cancer screening. It was also hypothesized that the Vietnamese population would have different trends …
