Conditions Of Cooperation Between Rats In The Prisoner's Dilemma Model, Malory B. Wodka

Honors Projects

Reciprocal cooperation is the act of working together with another individual to increase the likelihood that the other individual will continue to work together during future encounters. Reciprocal cooperation can be explained evolutionarily because it promotes the fitness of individuals in certain conditions. Cooperation is most commonly studied in humans. However less complex mammals such as rats display cooperative behaviors in certain conditions. This study examines the necessary conditions for cooperation in rats by testing the significance of housing conditions and prior interactions between cooperating rats. We found that rats did not cooperate at levels greater than chance.

Amygdalar Stimulation Produces Alterations On Firing Properties Of Hippocampal Place Cells, Eun Joo Kim, Earnest S. Kim, Mijeong Park, Jeiwon Cho, Jeansok J. Kim

Faculty Publications - Psychology Department

Stress is a biologically ubiquitous factor that, when perceived uncontrollable by humans and animals, can have lingering adverse effects on brain and cognitive functions. We have previously reported that rats that experienced inescapable-unpredictable stress subsequently exhibited decreased stability of firing rates of place cells in the CA1 hippocampus, accompanied by impairments in CA1 long-term synaptic potentiation and spatial memory consolidation. Because the elevated level of glucocorticoid hormones and the heightened amygdalar activity have been implicated in the emergence of stress effects on the hippocampus, we investigated whether administration of corticosterone and electrical stimulation of the amygdala can produce stress-like alterations …

Disaster Mental Health, Denise Bulling, Tarik Abdel-Monem

University of Nebraska Public Policy Center: Publications

People have always given aid and comfort to each other during times of disaster. However, attempts to structure and professionalize this assistance are fairly recent developments. Disaster mental health, as an evolving field of practice and study, is a collection of interventions and practices that are designed to address incident-specific stress reactions, rather than ongoing or developmental mental health needs. Traditional mental health practice is based on a medical model, with a clinician seeing a patient in an office setting. Disaster mental health introduces a paradigm shift, requiring that practitioners (clinicians and indigenous helpers) work with individuals and whole communities …

"...Bless Her Little Heart!": The Culture Of Honor And Emotion Recognition, Forrest J. Rackham

College of Graduate Studies: Theses & Dissertations

Author's abstract: Some researchers assert that cultural display rules may explain differences in perceiving emotions (Matsumoto, Yoo, & Chung, 2010). The current study examined the display rule of masking within the Southern culture of honor. It was hypothesized that masking within the culture of honor negatively affects emotion perception sensitivity, particularly in the speed and accuracy of recognizing anger. Southern undergraduate students were primed with the culture of honor and then presented with the Emotional Expression Multimorph Task. Participants chose one of the six emotions (i.e., sad, happy, surprise, fear, disgust, or anger). It was hypothesized participants in the masking …

Alexithymia, Social Constraints, And Self-Efficacy As Moderators Of Written Emotional Disclosure And Coping Skills Training: For Which Patients With Rheumatoid Arthritis Do These Interventions Improve Pain And Physical Functioning?, Jennifer Carty

Wayne State University Theses

Rheumatoid arthritis (RA) causes pain, disability, and inflammation. Written emotional disclosure (WED) and pain coping skills training (CST) improves adjustment, but effect sizes are small to moderate; research needs to identify patients most likely to benefit from WED and CST. A moderator analyses was conducted to determine if alexithymia, social constraints, or self-efficacy predicted health outcomes from interventions at 1-, 4-, and 12-month follow-up. Health assessed at baseline and at each follow-up. Patients were randomized to WED or equivalent control (Health Behavior Writing), and to CST or equivalent control (Arthritis Education). Findings from this study suggest that alexithymia and social …

Adolescent Characteristics And Peer Influence As Predictors Of Antisocial Behavior In Males, Benjamin D. Goodlett

Wayne State University Theses

Deviant peer influence during adolescence has been found to predict substance use, delinquency, and aggression. This study examined youth characteristics (prosociality, daring, and verbal ability) along with peer influence (deviant talk) as predictors of antisocial behavior. Peer influence, in the form of deviant talk, was also examined as a potential mediator between youth characteristics and antisocial behavior. The current study added to the literature by examining a slope measure of deviant talk as an organizing feature of peer discussions. Data were collected prospectively from a subsample of 178 youths participating in the Pitt Mother and Child Project. Findings supported daring, …

Father Involvement As A Predictor Of Preschool Children's Academic Readiness And Socioemotional Competence, Travis Alexzander Goldwire

Wayne State University Theses

Predictors of father involvement (FI) were examined. Associations between learning encouragement (LE) and socioemotional support (SS) in relation to later school readiness outcomes were examined. A subsample of residential fathers (n = 6150) from the ECLS-B was used. Hierarchical linear regressions and conceptual path analysis were used to conduct statistical analyses. Child sex, paternal employment, and the mother-father relationship were significant predictors of LE at 9 months. The mother-father relationship predicted LE at 2 years and SS at 9 months. LE at 9 months was a significant predictor of academic readiness indicators at preschool. LE at 2 years significantly predicted …

Sex Differences In The Dopaminergic Regulation Of Courtship, But Not Pairing Behaviors In Zebra Finches, Erin Marie Lowrey

Wayne State University Theses

Dopamine is one of the key ingredients in the glue that cements social bonds in vertebrates. The D2 dopamine receptor has been implicated in the regulation of monogamous pair bonding in the prairie vole. While dopamine affects courtship behaviors in the male zebra finch, the behavioral role of dopamine acting at D2 receptors in both males and females deserves further attention. We hypothesized that the D2 receptor would regulate courtship and pairing behaviors in the male and female zebra finch. Sixteen males and females were tested using a repeated measures design. On day 1, the zebra finches were injected with …

Determining Musical Preferences In Persons With Dementia: Comparing Caregiver Options To Stimulus Preference Assessment, Eva Christine Igler

All Graduate Theses, Dissertations, and Other Capstone Projects

The music therapy literature supports the use of individualized music in order to reduce problem behaviors among individuals with moderate to severe dementia; however, these interventions frequently rely on family members and/or staff to choose preferred music. Family members and caregivers are often inaccurate when choosing preferred stimuli for cognitively impaired individuals. The purpose of this study was to determine if family members and caregivers could accurately identify the preferred music of individuals with dementia. A single stimulus preference assessment was used to empirically determine preferred music and then these results were compared to family member and caregiver rankings. The …

The Ecological Validity Of The Self-Explanation Effect: The Deleterious Effect Of Music On Self-Explanations, Jason Geller, Robert J. Calin-Jageman

Modern Psychological Studies

One of the most powerful ways to boost learning is to require students to self-explain—to generate written or verbal explanations of their study material as they are studying. Although self-explaining is known to enhance learning across a wide range of ages and study materials, this empirical work has focused almost exclusively on optimal study conditions. Here we explore if selfexplaining is similarly effective in the presence of background music, a distraction students commonly elect to incorporate into their study routines. In the first study, 32 university students were asked to learn about neuronal action potentials while we varied both self-explaining …

The Effect Of Music Genre On A Memory Task, Darragh Bugter, Randy Carden

Modern Psychological Studies

This study examined the effects of two different music genres and silence on a memory task Sixty participants were randomly assigned to three groups which were exposed to rap music, classical music or silence while playing the Concentration game. The number of flips needed to complete the Concentration game was measured and served as the memory score. Results of a one-way analysis of variance detected a significant difference between the groups. A planned post hoc analysis found that the classical music group completed the Concentration game in significantly fewer flips than the rap group.

Problems In Using Diagnosis In Child And Adolescent Mental Health Services Research, Leonard Bickman, Lynne G. Wighton, E. Warren Lambert, Marc Karver, Lindsey Steding

Psychology Faculty Publications

This paper presents results from a three-part study on diagnosis of children with affective and behavior disorders. We examined the reliability, discriminant, and predictive validity of common diagnoses used in mental health services research using a research diagnostic interview. Results suggest four problems: a) some diagnoses demonstrate internal consistency only slightly better than symptoms chosen at random; b) diagnosis did not add appreciably to a brief global functioning screen in predicting service use; c) low inter-rater reliability among informants and clinicians for six of the most common diagnoses; and d) clinician diagnoses differed between sites in ways that reflect different …

Women, Alcoholics Anonymous, And Related Mutual Aid Groups: Review And Recommendations For Research, Sarah E. Ullman, Cynthia J. Najdowski, Ericka B. Adams

Psychology Faculty Scholarship

Recent literature reviews and meta-analyses have supported the effectiveness of Alcoholics Anonymous (AA) in helping members stop drinking and maintain sobriety. Despite the extensive body of research on AA, less attention has focused on differences in the efficacy of the program for and experiences of women as compared to men. Such a focus is warranted given that there are significant gender differences in the development and progression of alcoholism, impact of drinking, and response to treatment. This review synthesizes results of extant research on women in AA and similar mutual aid groups focused on problem drinking to describe the state …

Epigenetics: A Possible Mechanism Of Memory, Aliza Grossman Rubenstein

The Science Journal of the Lander College of Arts and Sciences

The following is an excerpt from the introduction to this article: The mind-body connection has fascinated philosophers and scientists for centuries. How is it possible that consciousness arises from a lump of matter known as the brain? How does neurons’ firing affect choice and beliefs? How do the electrochemical properties of the brain allow for the memory of events long after they’ve occurred? One of the most studied of these areas is that of memory. Researchers seek to understand the biological basis behind memory and how that biology is affected in individuals suffering from memory disorders.

Characterization Of The Behavioral, Biochemical And Molecular Indices Of Stress Produced By Nicotine Exposure And Withdrawal In Male And Female Rats, Oscar Valentin Torres

Open Access Theses & Dissertations

Introduction: Tobacco use is a major economic and health problem. Particularly concerning is that women consume more tobacco products, have a more difficult time quitting, and are less likely to benefit from cessation therapies than men. As a result, women are at higher risk of developing tobacco-related diseases. Women are generally more susceptible to stress and are more likely to cope with stress by smoking as compared to men. During abstinence, women also experience intense anxiety as compared to men and report that the anxiety-reducing effects of smoking are the main reason for continued use and relapse. Thus, stress produced …

Cognitive Profiles And The Impact Of Medication On Children With Attention Deficit Hyperactivity Disorder, Lucy J. Wimpenny

PCOM Psychology Dissertations

Attention Deficit Hyperactivity Disorder (ADHD) is one of the most frequently diagnosed disorders in children and adolescents. Individuals with ADHD often display behavioral symptoms, including inattention and/or impulsivity, which can also lead to struggles in the school setting. Current research has suggested that deficits in processing speed and working memory are common in individuals diagnosed with ADHD and are often seen on measures of cognitive ability. Positive outcomes have been associated with the use of psychostimulant medication to treat the symptoms of ADHD, although little research has supported this form of treatment to improve cognitive functioning in individuals diagnosed with …

The Relationship Between Parental Stress, Cognitive Distortions, And Child Psychopathology, Daniel Kennedy

PCOM Psychology Dissertations

While there are a number of factors that may contribute to maladaptive parenting behaviors, parental stress has consistently been related to the increased risk of child maltreatment and, ultimately, the development of childhood. The question then is what drives parental stress and what are those key factors? Based on previous research, there are multiple parental, child, and environmental factors that lead to parental stress, but there is not a clear understanding of what initially drives parental stress. Based on cognitive behavioral models of stress and Abidin’s theory of parental stress, it is theorized that parental cognitions play an important role …

Selective Mutism: Identification Of Subtypes And Influence On Treatment, Christy A. Mulligan

PCOM Psychology Dissertations

Selective Mutism (SM) is a psychiatric disorder with a relatively low incidence that impairs social communication in some settings. There are many characteristics that appear similar in some children but are absent in others. Therefore, it was hypothesized that there may be distinct SM subtypes that warrant differential diagnosis and treatment strategies. In this study, 442 Selective Mutism Comprehensive Diagnostic Questionnaires (SM-CDQ) were analyzed to help identify children with specific characteristics that made their SM unique. Participants ranged in age from 3 to18 years old and met criteria for SM. The data were coded based on 203 variables and were …

Sensory Processing In Children With Adhd: A Classroom Study And Rational Item Analysis, Jason Mathison

PCOM Psychology Dissertations

In the classroom, distinguishing between sensory modulation disorder (SMD), one proposed subtype of Sensory Processing Disorder, and attention deficit hyperactivity disorder (ADHD) can be difficult given their similar behavioral manifestations. The overlap between these two disorders and the prevelance of rating scales used for gathering diagnostic information warrant a closer look at items on commonly used rating scales to ensure discriminative validity. This pilot study examined specific patterns of SMD in 24 children with ADHD using the Sensory Profile School Companion (SPSC), which includes four components of SMD, namely, Seeking, Avoiding, Registration, and Sensitivity. As hypothesized, the majority of teacher …

Clinician Factors In Psychotherapy Disparities For People With Intellectual Disabilities And Co-Occurring Mental Illness, Timothy Barksdale

PCOM Psychology Dissertations

An estimated 4.5 million Americans with intellectual disabilities (ID) have lived in the community for over twenty years now, following the closing of institutions that once isolated them from the public (Scott, Lakin & Larson, 2008). It has since become evident that this group has the same and more vulnerabilities of developing mental illness than the general public but often lack access to therapeutic service (Whitaker & Read, 2005). Unfortunately society’s lack of interaction with and education about this population has contributed to a number of misconceptions and fears. The hypothesized variables for the behavioral health disparity included: level of …

Examining Gender And Socio-Economic Status On The Emotional Intelligence Of Early Adolescents, Alicea J. Davis

PCOM Psychology Dissertations

The purpose of this study was to examine emotional intelligence and its impact on the maturational process of male and female early-adolescent youth. Demographic variables, such gender, socio-economic status, ethnicity, and educational status were, valued against emotionality factors such as intrapersonal stress, interpersonal stress, adaptability, general mood, and overall emotional intelligence (EQ). The study utilized a non-experimental, correlational design examining archival data. The participants consisted of approximately, early adolescent fifth-grade students aged 10-13 years. The participants were administered the Bar-On Emotional Quotient Inventory (BarOn EQ-I:YV) and a demographic questionnaire. Descriptive statistics were used to describe the population sample. A Pearson …

Attention To Psychosocial Concerns Related To Lqts: A Survey Of Medical Providers, Elizabeth Conlin

PCOM Psychology Dissertations

Long QT Syndrome (LQTS) is a heritable condition characterized by syncopal episodes, arrhythmias, and sudden cardiac death in otherwise healthy individuals. Current research, although underrepresented, on the quality of life and psychosocial stressors indicate that some individuals experience depression and anxiety as a result of this chronic medical illness. A survey was created and administered to cardiologists and allied professionals, who offer medical services to LQTS patients, and belong to the Pediatric Arrhythmia and Congenital Electrophysiology Society (PACES). A Likert scale survey was developed for selfadministration and posted in an email for PACES members to complete voluntarily. This survey study …

Acculturation, Psychological Distress, And Family Adjustment Among Russian Immigrants In The United States, Eugene Dunaev

PCOM Psychology Dissertations

The purpose of this research was to investigate the effect of acculturation differences on psychological distress and family functioning in non-Jewish Russian immigrant families. Potential mediating effects of social support and parenting style and moderating effect of the child’s gender were investigated using regression analysis. The sample consisted of 80 Russian immigrant mother-child dyads residing in the northeast region of the U.S. The study included independent assessment of acculturation to American and Russian cultures. Results confirm the presence of associations between acculturative differences, psychological distress, and family problems. A mediational role of social support and parenting style on the impact …

An Evaluation Of A Group Nutritional Program In A Population Of Obese Individuals With Psychiatric Disabilities, Jamie Via

PCOM Psychology Dissertations

Individuals with serious mental illnesses are at high risk for obesity. The increased risk of obesity and comorbid medical conditions among individuals with serious mental illnesses has increased the need to seek and utilize effective treatments to address obesity in this population. In efforts to address the need for effective treatment, Eli Lilly and Company developed the Solutions for Wellness program. The aim of this study was to examine if the Solutions for Wellness nutritional program was effective in increasing wellness knowledge and increasing healthy lifestyle choices within a small sample of obese individuals with serious mental illnesses. The nutritional …

Overweight, Obesity, And Mental Illnesses: Weight Loss Treatment, Michelle Huang

PCOM Psychology Dissertations

For the past 30 years, overweight and obesity has increased at alarming rates in the general population. This public health crisis has affected persons with mental illnesses as it has those in the general population. Little is known about how individuals with psychiatric problems respond to weight-loss treatment compared to the general population. The current study examines the efficacy of a cognitive-behavioral group weight-loss intervention with such individuals. The study also examines self-esteem, motivation, and the involvement of a support person in treatment as predictor variables. The treatment was shown to be effective regardless of depression severity. However, while all …

Early Adolescent Non-Suicidal Self-Injury And Sensory Preference Differences: An Exploratory Study, Jacquelyn Shea Christensen

CGU Theses & Dissertations

BACKGROUND: Non-suicidal self-injury (NSSI) occurs in 13% to 20% of adolescents, and is often indicative of deeper internal or social problems. A close review of current explanatory models of NSSI suggested that underlying individual sensory preferences may contribute substantial explanations for the self-regulatory functions of NSSI, as well as have implications for treatment approaches. In the context of integrating sensory processing models with prominent functional NSSI models, this dissertation research compared sensory preferences in youth who engaged in NSSI to sensory preferences of youth who did not engage in NSSI.

OBJECTIVE: NSSI-engaging youth were hypothesized to have lower threshold sensory …

Investigation Into The Specificity Of Angiotensin Ii-Induced Behavioral Desensitization, Peter J. Vento, Kevin P. Myers, Derek Daniels

Faculty Journal Articles

Angiotensin II (AngII) plays a key role in maintaining body fluid homeostasis. The physiological and behavioral effects of central AngII include increased blood pressure and fluid intake. In vitro experiments demonstrate that repeated exposure to AngII reduces the efficacy of subsequent AngII, and behavioral studies indicate that prior icv AngII administration reduces the dipsogenic response to AngII administered later. Specifically, rats given a treatment regimen of three icv injections of a large dose of AngII, each separated by 20 min, drink less water in response to a test injection of AngII than do vehicle-treated controls given the same test injection. …

Social Experience, Depression, And Alcohol Abuse In College Age Females, Ann Cooper

HIM 1990-2015

Past research has explored social experience in relation to depression among college females. Other studies have investigated the relationship between social experience and alcohol use among college students. However, there is a lack of research on the relationship among all the three variables, social experience, depression, and alcohol use, in female college students. In the present study, 132 traditional age female college students completed a Brief Social Experience Rating Scale, the Beck Depression Inventory (BDI), and the Alcohol Use Disorder Identification Test (AUDIT). The results did not show a relationship between AUDIT scores and social experience ratings, but individuals who …

Effects Of Early Intervention Services On Adaptive Functioning, Osslyn Sam

PCOM Psychology Dissertations

In 1986, Congress enacted Public Law 99-457, Part H of the Individuals with Disabilities Education Act (IDEA). This law, currently referred to as Part C, was established in response to the growing number of children born with developmental delays. Infants born prematurely, addicted to drugs, or with conditions such as Down Syndrome face challenging lives. Part C allows for eligible infants, ages birth to three years to receive free early intervention services to address their individual delays. Previous studies have shown that children who have participated in early intervention programs have benefited in various areas of their overall development. The …
