Pathways To Obesity In Women : The Role Of Coping And Emotional Eating, Veronica Nicole Stotts
Pathways To Obesity In Women : The Role Of Coping And Emotional Eating, Veronica Nicole Stotts
Legacy Theses & Dissertations (2009 - 2024)
Obesity is a major health crisis in the United States, with approximately two-thirds of the population qualifying as overweight and, of those, almost one half qualifying as obese (CDC, 2007). While there are a myriad of causes of obesity, a great deal of evidence shows that many individuals, and particularly women, eat as a coping response to stress (e.g., Greeno & Wing, 1994). Therefore, one's ability to cope, or the process by which individuals deal with situations that involve stress or threat, may be a factor that contributes to increased body mass index, or BMI, a common measure of obesity. …
Is Competitive Behavior Controlled By Its Consequences? The Effects Of Omission Training On Competitive Behavior In Rats, Melinda Mallory, '09
Is Competitive Behavior Controlled By Its Consequences? The Effects Of Omission Training On Competitive Behavior In Rats, Melinda Mallory, '09
Honors Projects
Recent research has examined competitive behavior in rats. When multiple rats are placed in an open field with a single feeder delivering pellets on a Variable Interval Schedule, the rats typically engage in a competitive wrestling response near the feeder tube. This response has been observed in several different experiments, but little is known about its specific nature. One possibility is that the response is a traditional operant. Although there is no explicit contingency with reinforcement, rats that do not engage in the response are unlikely to consume pellets. Alternatively, the competitive response might represent a species-specific foraging mode, controlled …
The Effects Of Medial Septal Modification On The Theta Rhythm Of The Amygdala, Colleen E. Mcshane, '09
The Effects Of Medial Septal Modification On The Theta Rhythm Of The Amygdala, Colleen E. Mcshane, '09
Honors Projects
The theta rhythm is a 3- 1 2 Hz electroencephalographic (EEG) oscillatory phenomenon that has been recorded from the hippocampus of small animals during large motor movements, periods of arousal, and memory tasks. Theta denotes the amount of brain synchrony occurring, with higher theta amplitude corresponding to more synchrony among individual neurons. The proposed pacemaker of the hippocampal theta rhythm is the medial septal area (MSA), which consists of neurons that fire rhythmically in frequencies corresponding to the theta rhythm. Despite the proven physical connection between the MSA and the amygdala, there is uncertainty as to whether the MSA serves …
Why Can't We Be Friends?: The Effects Of Disclosure And Severity On Typical Students' Attitudes Toward Peers With Autism Spectrum Disorders, Jacqueline M. Dowjotas, '09
Why Can't We Be Friends?: The Effects Of Disclosure And Severity On Typical Students' Attitudes Toward Peers With Autism Spectrum Disorders, Jacqueline M. Dowjotas, '09
Honors Projects
The autism spectrum disorders (ASDs) are characterized by deficits in social interaction, communication, and restrictive and repetitive behaviors and interests. Although many children with autism desire social interaction, they tend to have a difficult time mastering conversation skills and socially appropriate behavior. In addition, they have fewer and lower quality friendships when compared to typical peers, and they often face negative stigma from their typical peers. The current study was used to investigate typical students' attitudes toward hypothetical peers with varying degrees of ASDs. Participants (N = 61) read and responded to vignettes that depicted adolescents, in which severity of …
Youth In Out-Of-Home Care: The Question Of Psychological Agency, Lauren M. Polvere
Youth In Out-Of-Home Care: The Question Of Psychological Agency, Lauren M. Polvere
Dissertations, Theses, and Capstone Projects
This dissertation examines the critical perspectives of formerly institutionalized youth with psychiatric disabilities through the lens of psychological agency. Framed in sociohistorical perspective, a theoretical shift is suggested for understanding the development of youth with mental health placement histories. In contrast to clinical approaches, which focus on psychopathology of youth in placement, this study elucidates the agentic meaning making processes employed by youth as they negotiate various treatment contexts and engage in activism. Participants in the study are 12 youth between the ages of 16-23, who are involved in peer-run groups for young people with out-of-home treatment experience, and 4 …
Intuition, Rational Analysis And The Relation Between Implicit And Explicit Attitudes, Mervyn Lee Whitfield
Intuition, Rational Analysis And The Relation Between Implicit And Explicit Attitudes, Mervyn Lee Whitfield
Theses and Dissertations (Comprehensive)
Across four experiments, reliance on rational analysis reduced the correspondence between implicit and explicit attitudes relative to reliance on intuition. In each experiment, implicit attitudes were measured, and then participants were induced to rely on either rational analysis or intuition. Following this manipulation, explicit attitudes were measured. We found that participants reported explicit attitudes that were more or less consistent with implicit attitudes depending on whether they relied more on intuitions or rational analysis. Notably, rational analysis only reduced the correspondence between implicit and explicit attitudes when it led participants to consider reasons for their attitudes that were inconsistent with …

Community Consultation And Environmental Justice In The Regent Park Revitalization, Jacqueline De Schutter
Theses and Dissertations (Comprehensive)
The neighbourhood of Regent Park, located in the east end of downtown Toronto, Ontario, is the oldest and largest public housing development in Canada. In 2002, under its new management by the Toronto Community Housing Corporation, the development was announced to undergo a total redevelopment to be completed over 12 years. The revitalization of Regent Park has involved, among other things, an extensive and uniquely designed community consultation process, as well as a redesign for its green space. The community consultation process is examined through a case study method, wherein the use of archival documents, interviews with community staff, and …
Made Me Who I Am: An Examination Of Grandparent And Parent Value Teaching And Young Adult Generativity, Identity, And Adjustment, Elise Bisson
Theses and Dissertations (Comprehensive)
Intergenerational value transmission plays an important role in child socialization. Although much research has been done on parent to child value teaching, there is little research on grandparent to grandchild value teaching. The purpose of this study was to explore parent and grandparent value teaching and how it relates to young adult generativity, identity development, and adjustment. This study involved 100 young adults, between the ages of 25 to 29 with a mean age of 26, taken from a longitudinal sample of participants in 2006. Participants were asked to tell parent and grandparent value teaching stories, in which they described …

Beyond Indigenization: International Dissemination Of Research By Majority-World Psychologists, John G. Adair, Yoshi Kashima, Maria Regina Maluf, Janak Pandey
Papers from the International Association for Cross-Cultural Psychology Conferences
Analyses of the affiliations of authors of articles published in targeted samples of North American and international journals revealed trends toward increasing international publication by psychologists from countries outside the U.S., i.e., from countries in the rest of the world (ROW). Relatively few of these ROW publications came from psychologists from developing countries. Because developing countries are most numerous and represent the majority of the people in the world, their contribution to the world of psychology is important. Following a summary presentation of data for each journal for psychologists from East Asia, Latin America and the Caribbean, and South Asia …

Compulsive Hoarding In Children: Six Case Studies, Edward H. Plimpton, Randy O. Frost, Brianna C. Abbey, Whitney Dorer
Compulsive Hoarding In Children: Six Case Studies, Edward H. Plimpton, Randy O. Frost, Brianna C. Abbey, Whitney Dorer
Psychology: Faculty Publications
Semi-structured interviews were conducted with the parents of six children who showed signs of compulsive hoarding. The cases revealed a wide variety of hoarding behaviors. Hoarding manifested in difficulties in discarding and maintaining control over possessions. Few cases had problems with clutter or excessive acquisition. In three cases hoarding was episodic and stress-related. Most of the cases showed overlapping ADHD symptoms and a majority demonstrated problems with perfectionism. Only two had clear obsessive-compulsive disorder, although concerns about others touching or moving possessions, which was present in all of the cases, may represent a form of ordering and arranging compulsions. None …

Is A Sense Of Inequity An Ancestral Primate Trait? Testing Social Inequity In Cotton Top Tamarins, Julie J. Neiworth, Elizabeth T. Johnson, Katherine Whillock, Julia Greenberg, Vanessa Brown
Is A Sense Of Inequity An Ancestral Primate Trait? Testing Social Inequity In Cotton Top Tamarins, Julie J. Neiworth, Elizabeth T. Johnson, Katherine Whillock, Julia Greenberg, Vanessa Brown
Psychology Faculty Work
To address a controversy in the literature concerning whether monkeys show an aversion to inequity, individuals of a New World monkey species, cotton top tamarins (Saguinus oedipus) were tested in an offering task and in a bartering task. At issue was whether the monkeys rejected rewards because of a violation of expectancy of the preferred reward, or whether they rejected rewards because of a sensitivity to socially mediated inequity. The data from both tasks indicated that the subjects were more likely to reject when preferred rewards were presented, either because of another animal eating the reward (the social condition) or …
Thinking About Me: How Social Awareness Evolved, Julie J. Neiworth
Thinking About Me: How Social Awareness Evolved, Julie J. Neiworth
Psychology Faculty Work
—Humans seem unique in their consideration of others’ goals, motivations, intentions, and needs. But the human form of social awareness did not spring from nowhere; certain mechanisms shared across primates formed the foundation from which these processes derived. A review of recent nonhuman primate research points to particular ancestral mechanisms, including an interest in images moving in synchrony with self, a mirror neuron system that responds in the same way to actions made by the self and by others, and inherited social tolerance that provided the bases for social thinking. Still there is a gap in tracking social awareness from …
A Study Of Possible Pre-Cognitive Advantages Of Bilingualism, Marisela Gutierrez
A Study Of Possible Pre-Cognitive Advantages Of Bilingualism, Marisela Gutierrez
Open Access Theses & Dissertations
Past research has suggested that second language acquisition has a beneficial effect on the development of inhibitory control processes in children and adults. This has been referred to as the "bilingual advantage" and is most commonly quantified using the Simon task. Whether the bilingual advantage extends to precognitive mechanisms has not yet been examined. The goals of this study were to examine the bilingual advantage in university students; and to examine whether the bilingual advantage extends to the precognitive filtering mechanism of sensorimotor gating. It was predicted that, as compared to monolinguals, bilingual university students would have greater inhibitory control, …
Inhibitory Deficits In Children With Attention-Deficit/Hyperactivity Disorder: Intentional Versus Automatic Mechanisms Of Attention, Mark T. Fillmore, Richard Milich, Elizabeth P. Lorch
Inhibitory Deficits In Children With Attention-Deficit/Hyperactivity Disorder: Intentional Versus Automatic Mechanisms Of Attention, Mark T. Fillmore, Richard Milich, Elizabeth P. Lorch
Psychology Faculty Publications
Application of theoretically based tasks to the study of the development of selective attention has led to intriguing new findings concerning the role of inhibitory mechanisms. This study examined inhibitory mechanisms using a countermanding task and an inhibition of return task to compare deficits in intentionally, versus reflexively, controlled inhibition of attention in children with attention deficit hyperactivity disorder. Fifty children with attention-deficit/hyperactivity disorder (ADHD) were classified into one of three subtypes: predominantly inattentive (ADHD/PI), combined (ADHD/C), and those children with ADHD/C who also met criteria for comorbid oppositional defiant disorder (ADHD/C + ODD). The groups were compared to a …
Role Of Assigned Team Goals In The Relationship Between Individual Difference Factors And Self-Set Goals In A Pre-Team Context, Anupama Narayan
Role Of Assigned Team Goals In The Relationship Between Individual Difference Factors And Self-Set Goals In A Pre-Team Context, Anupama Narayan
Browse all Theses and Dissertations
The purpose of the present study was to examine the effects of individual difference factors, i.e., core self evaluations, cognitive ability, and task specific self-efficacy, on self-set goals and whether those effects were moderated by an assigned team goal in a pre-team context. It was hypothesized that the relationship between individual difference factors and self-set goals for potential team members would be differentially affected by the difficulty of the assigned team goal. I assessed these relationships for individual performance and individual satisfaction. In addition, I examined whether gender, task type, and team composition interacted in their effects on self-set goals. …

Examining Cultural Competence Among Osteopathic Medical Students , Sooni Lee
PCOM Psychology Dissertations
With the growing number of racial and ethnic minorities in the United States, there also has been a rise in health disparities. Ethnic minorities have been experiencing an overabundance of medical issues, particularly chronic diseases like cardiovascular disease, diabetes, and cancer. Although these chronic diseases are preventable, ethnic minorities are at greater risk for death from them. Possible contributing factors to the increase in health disparities include limited medical attention and follow-up appointments with physicians and the physician-patient relationship. The purpose of this study was twofold: to examine cultural competence among osteopathic medical students and to examine their attitudes toward …

Perception Of Control And Awareness Of Deficit In Individuals With Neurological Impairment In A Clinical Sample , Donna Marie Struck
PCOM Psychology Dissertations
Acquired brain injury is considered to be one of the most important public health concerns in the United States, with approximately 1.2 million adults that meet the criteria for chronic brain disease, brain disorder, or injury each year. Medical costs directly related to injury, in addition to the indirect costs related to job loss, totaled an estimated 60 billion dollars in the year 2000. Subsequent impairment following brain injury yields a complicated neurobehavioral sequelae of deficits. Anosognosia, specifically, the deficit of the patient's inability to acknowledge, or even recognize impairments, is common following brain injury. In a review of the …

PCOM Psychology Dissertations
The purpose of this dissertation project was threefold: to develop a cognitive-behavioral manual for therapists, a self-help manual for depressed mothers, and a guide to assist children, aged 6 to 11, through the risks of depression was paramount in the design of this project. Given a paradigm shift in the field of psychotherapy towards resilience, this manual is timely in that it is a valuable resource for promoting resilience outcomes in both mothers and their children. This manual includes a variety of social, emotional, and behavioral activities for mothers and children, allowing mothers to be at the forefront of establishing …
Relationship Between Social Problem-Solving Skills, Quality Of Life, And Family Adjustment In Caregivers Of Children With Developmental Disability, Bonita Ellen Fisher
Relationship Between Social Problem-Solving Skills, Quality Of Life, And Family Adjustment In Caregivers Of Children With Developmental Disability, Bonita Ellen Fisher
PCOM Psychology Dissertations
This study focused on the relationship between a caregiver's problem solving skills, their perceived quality of life, their family's adjustment to their child's disability, and the potential for mediation of those relationships by the child's behavior. A total of 111 parents completed the Social Problem Solving Skills Inventory-Revised, short form (SPSI-R:S), the World Health Organization Quality of Life Assessment, brief version (WHOQOL-BREF), the Family Impact of Childhood Disability Scale (FlCD), the Nisonger Child Behavior rating Form (NCBRF) and a demographics questionnaire. Analyses of the data by Pearson product-moment correlation coefficient identified significant correlations between scores on the problem orientation components …
The Power Of The Mind : The Relationship Between Mindfulness, Quality Of Life And Anxiety For Older Adults With Chronic Illness , Tracy Elizabeth Ransom
The Power Of The Mind : The Relationship Between Mindfulness, Quality Of Life And Anxiety For Older Adults With Chronic Illness , Tracy Elizabeth Ransom
PCOM Psychology Dissertations
This dissertation examines the relationship between mindfulness training and older adults with chronic illness and a documented clinical anxiety diagnosis. Six subjects (mean age = 69 years) who met criteria for a DSM-IV-TR anxiety condition and who endorsed one or more chronic illnesses participated in an 8-week customized mindfulness training program. The research evaluated the impact of mindfulness training and practice on depression, quality of life, health satisfaction and anxiety. This dissertation's findings suggest that of these variables, state and trait anxiety were significantly reduced at the conclusion of the program. Given these findings, this research proposes that anxiety in …
Nonlinear Dynamics Of Infant Sitting Postural Control, Joan E. Deffeyes
Nonlinear Dynamics Of Infant Sitting Postural Control, Joan E. Deffeyes
Department of Psychology: Dissertations, Theses, and Student Research
Sitting is one of the first developmental milestones that an infant achieves. Thus measurements of sitting posture present an opportunity to assess sensorimotor development at a young age, in order to identify infants who might benefit from therapeutic intervention, and to monitor the efficacy of the intervention. Sitting postural sway data was collected using a force plate from infants with typical development, and from infants with delayed development, where the delay in development was due to cerebral palsy in most of the infants in the study. The center of pressure time series from the infant sitting was subjected to a …

Noninvasive Physiological Measures And Workload Transitions:An Investigation Of Thresholds Using Multiple Synchronized Sensors, Lee Sciarini
Electronic Theses and Dissertations
The purpose of this study is to determine under what conditions multiple minimally intrusive physiological sensors can be used together and validly applied for use in areas which rely on adaptive systems including adaptive automation and augmented cognition. Specifically, this dissertation investigated the physiological transitions of operator state caused by changes in the level of taskload. Three questions were evaluated including (1) Do differences exist between physiological indicators when examined between levels of difficulty? (2) Are differences of physiological indicators (which may exist) between difficulty levels affected by spatial ability? (3) Which physiological indicators (if any) account for variation in …
