The Effects Of Courtship And Pairing Behavior On The Nonapeptide And Noradrenergic Systems Of Adult Male And Female Zebra Finches, Erin Lowrey Ondercin

Wayne State University Dissertations

Social relationships are complex and likely involve the multiple neural circuits, including those involved in learning, memory, motivation, and attention. Two neurotransmitter pathways highly involved in these neural circuits are norepinephrine (NE) and the nonapeptides, vasopressin (AVP) and oxytocin (OT). There is extensive research implicating a role for the nonapeptides in trust, sociality, parental care, and romantic relationships. There is little direct evidence for the role of nonapeptides in monogamous relationships in any species other than the prairie vole (Goodson 2013). However, there is evidence that nonapeptides are important in pair bonding for both male and female zebra finches (Lowrey …

Child Maltreatment, Problem Alcohol Use And Physical Revictimization: Examining Longitudinal Trajectories In A Nationally Representative Sample, Kathryn Mariah Zumberg Smith

Wayne State University Dissertations

Past investigations examining the relationships between child maltreatment, alcohol use and physical revictimization have been limited by their use of cross-sectional designs and their focus on childhood sexual abuse and sexual revictimization. In addition, there is a paucity of epidemiological studies examining child maltreatment, alcohol use, and physical revictimization. The present study sought to address these limitations by examining relationships between child maltreatment, problem alcohol use, and physical revictimization in a nationally representative sample. Data were analyzed from the public-use data set of the National Longitudinal Study of Adolescent to Adult Health (Add health; Harris & Udry, 2014), waves I-IV. …

The Impact Of Age On Workplace Motivation: A Person-Centered Perspective, Keith Lynn Zabel

Wayne State University Dissertations

The present study used the person-centered approach to examine how profiles based upon six different age conceptualizations differentially impact workplace motivation. In the first known study to examine all conceptualizations of age simultaneously, results suggested the age conceptualizations of subjective age and health significantly impact growth motives for older workers, but not social or security motives. Results suggest social motives are influenced more by chronological age as opposed to other conceptualizations of age. Implications for practitioners in designing and implementing HR activities (e.g., succession planning) and researchers in utilizing all the conceptualizations of age and studying workplace interventions are discussed.

The Semantic Memory Imaging In Late Life Pilot Study, Michael Adam Sugarman

Wayne State University Dissertations

Introduction: Several functional magnetic resonance imaging (fMRI) studies have analyzed the famous name discrimination task (FNDT), an uncontrolled semantic memory probe requiring discrimination between famous and unfamiliar individuals. Completion of this simple task recruits a semantic memory network that has shown utility in determining risk for Alzheimer's disease (AD). Specific semantic memory probes using biographical information associated with famous individuals may build on previous findings and yield superior information regarding risk for AD.

Method: Sixteen cognitively intact elders completed the FNDT and two novel tasks during fMRI: Categories (matching famous individuals to occupational categories) and Attributes (matching famous individuals to …

An Analysis Of Virtual Place Learning/Navigation In Children And Young Adults Prenatally Exposed To Alcohol, Neil Christopher Dodge

Wayne State University Dissertations

Fetal alcohol spectrum disorder refers to the spectrum of disorders resulting from prenatal alcohol exposure and is the leading cause of preventable mental retardation. Rodent studies have found that prenatal alcohol exposure impairs performance on the Morris water maze. This task requires the rodent to use distal room cues to locate a hidden platform in a pool of opaque water. Successful performance on this task is dependent upon hippocampal function. Rodents prenatally exposed to alcohol are impaired on the Morris water maze and show damage to hippocampal neurons. A human analogue of the Morris water maze, the virtual water maze …

Analgesia Followed By Long-Term Hyperalgesia Generated By Disinhibition Of The Basolateral Amygdala, Derek Atchley

Wayne State University Theses

Stress produces bimodal effects on pain peception. During exposure to a stressor pain responses are inibited (i.e. stress-induced analgesia). However, following long-term exposure to a stressor increases in responsiveness to painful stimuli may develop (i.e. stress-induced hyperalgesia). Here I evaluated how a key component of the subcortical defense circuit and target of stress hormones contributes to the development of both stress-induced analgesia and hyperalgesia. Bicuculline methiodide, a GABAA antagonist, injected into the basolateral amygdala was used to mimic the neural effects of a stressor or threat exposure. Immediately following injection pain responsiveness was decreased as measured by vocalizations after discharge …

Development Of A Financial Decision-Making Self-Efficacy Measure For Older Adults, Evan Gross

Wayne State University Theses

Financial decision-making is important for older adults, and many are at increased risk for elder financial exploitation due to a combination of biological, social, and psychological factors. The role of self-efficacy for financial decision-making in this population has received little attention from researchers, but evidence suggests it may be a critical aspect in motivating positive decisions and avoiding exploitation. This study developed the Financial Decision-Making Self-Efficacy Scale (FDMSES) for older adults. Participants (N = 200, mean age = 71.5) completed the Lichtenberg Financial Decision-Making Rating Scale (LFDRS) and a neuropsychological test battery. Items from the LFDRS related to financial decision-making …

Diabetes Interaction Study: Communicating Understanding And Social Support, Dana K. May

Wayne State University Dissertations

The current study evaluated a brief individualized feedback intervention developed to improve communication style of parents with an adolescent with type 1 diabetes. Seventy-nine parent-adolescent dyads (13-18 years) were randomized to receive a single session of brief feedback to target parental person-centered communication skills (n = 39) or to receive an educational comparison group (n = 40). Families were asked to discuss a diabetes related problem. A clinician concurrently rated the parent’s communication skills to identify communication strengths and weaknesses. Parents in the feedback group received feedback on their use of person-centered communication during the conversation using motivational interviewing techniques. …

Fear Of Alzheimer's Disease And Its Role In Memory Monitoring And Control, Annalise Marie Rahman

Wayne State University Dissertations

Introduction: Fear of Alzheimer’s disease (FAD), or Anticipatory Dementia, is a healthy adult’s misinterpretation of everyday memory failures as indicators of developing dementia. The current study investigated the construct of FAD and aimed to contextualize FAD within the Health Belief Model through development of a new scale, the Anticipatory Dementia Index (ADI). The study also assessed the relationship between FAD and metacognitive monitoring and metacognitive control.

Methods: 94 cognitively-intact community-dwelling older adults with and without a history of family history of AD completed questionnaires regarding their subjective memory complaints, state and trait anxiety, depression, and multiple measures of FAD, including …

Management Safety Climate And Violence Prevention Climate: A Mediational Model For Healthcare Employee Outcomes, Lydia Hamblin Hamblin

Wayne State University Dissertations

Workplace violence is defined as aggressive acts against employees ranging from verbal abuse, threats, and bullying, to physical assault (OSHA, 2002; Jackson, Clare, & Mannix, 2002). The two purposes of this study were (1) to differentiate two specific forms of psychological climate related to workplace violence on a work unit: Violence Prevention Climate (VPC) and Management Safety Climate (MSC), and (2) to test a causal model focusing on the relationship between these climates and their effects on relevant outcomes for at-risk employees in the healthcare industry. MSC was expected to partially mediate the effects of VPC on four outcomes: work …
