Self And Communication In Long-Term Romantic Relationships, Farshad Michael Sadr

Online Theses and Dissertations

The purpose of this study was to further our understanding of how individuals in heterosexual romantic relationships resolve conflict and why the identified persuasion attempts are occurring. This study proposes a two-pathway model of how socialization predicts conflict communication strategies through self-construal and relationship goals. It is hypothesized that a) gender socialization and romantic relationship power influence the dominate type of self-construal an individual holds, b) parenting goals are more strongly predicted by relational interdependent self-construal than physical self-construal and that mating goals are more strongly predicted by physical self-construal than relational interdependent self-construal, c) direct conflict communication strategies are …

Human-Like Nsg Mouse Glycoproteins Sialylation Pattern Changes The Phenotype Of Human Lymphocytes And Sensitivity To Hiv-1 Infection, Raghubendra S. Dagur, Amanda Branch-Woods, Saumi Mathews, Poonam S. Joshi, Rolen M. Quadros, Donald W. Harms, Yan Cheng, Shana M. Miles, Samuel J. Pirruccello, Channabasavaiah B. Gurumurthy, Santhi Gorantla, Larisa Y. Poluektova

Journal Articles: Munroe-Meyer Institute

BACKGROUND: The use of immunodeficient mice transplanted with human hematopoietic stem cells is an accepted approach to study human-specific infectious diseases such as HIV-1 and to investigate multiple aspects of human immune system development. However, mouse and human are different in sialylation patterns of proteins due to evolutionary mutations of the CMP-N-acetylneuraminic acid hydroxylase (CMAH) gene that prevent formation of N-glycolylneuraminic acid from N-acetylneuraminic acid. How changes in the mouse glycoproteins' chemistry affect phenotype and function of transplanted human hematopoietic stem cells and mature human immune cells in the course of HIV-1 infection are not known.

RESULTS: We mutated mouse …

Social Anxiety, Quality Of Life, And Healthy Lifestyle Behaviors Of Women With Infertility Problems, Esra Savaş

Walden Dissertations and Doctoral Studies

Not having a child has significant psychosocial effects on women experiencing infertility problems. There is a gap in research on social anxiety, quality of life, and healthy lifestyle behaviors of women during infertility, fertility treatment, and subsequent pregnancy. The purpose of this quantitative comparative study was to investigate the social anxiety, quality of life, and healthy lifestyle behaviors of Turkish women with infertility issues and Turkish women who conceived after infertility treatment, as measured by the Liebowitz Social Anxiety Scale, the Fertility Quality of Life Questionnaire, and the Healthy Lifestyle Behavior Scale II. The social support and stress buffering theory …

Learned Helplessness In Industrial-Organizational Psychology: Relationships With Locus Of Control, Self-Efficacy, And Feedback-Seeking Behavior, Nicholas Kovacs

Browse all Theses and Dissertations

Researchers have suggested that self-efficacy and feedback-seeking behavior (FSB) are effective in enhancing performance. To improve performance in the workplace, research should focus on how psychologists can enhance these constructs in employees. Though locus of control (LOC) relates to self-efficacy and increased FSB, research has revealed issues in LOC (e.g., failure to predict performance, range restriction, failure to predict behaviors). The current study examined the effects of perceived “lack of control”, learned helplessness, over LOC on both self-efficacy and FSB in two different samples: a student sample (N = 321) and a work sample (N = 794). Learned helplessness accounted …

The Development Of A Lexicon For The Communication Of Action In Cooperative Work, Claire Supriya Shah

Browse all Theses and Dissertations

This research expands upon the research conducted by Clark and Wilkes-Gibbs (1986) on how individuals collaborate and reach common ground in the domain of objects into the domain of action. Pairs of participants (N = 22) were asked to complete a set of six maneuvers with a remote-control car. Dialogue was transcribed and analyzed for total word count, verb phrase count, number of turns taken, number of errors committed, and selected other linguistic characteristics. Total word count, verb phrase count, number of turns taken, and number of errors committed all significantly decreased over time, either linearly or logarithmically. This research …

Using Eeg To Examine The Top Down Effects On Visual Object Processing, Joseph D. Borders

Browse all Theses and Dissertations

Object recognition entails a complex interplay between top-down and bottom-up signals. Yet, limited research has investigated the mechanisms through which top-down processes, such as task context and behavioral goals impact the neural basis of visual object processing. Using electroencephalography (EEG), we studied the temporal dynamics of task and object processing to identify how early the impact of task can be observed. We recorded ERPs from participants as they viewed object images from four categories spanning animacy (Inanimate: roller-skate, motorbike; Animate: cow, butterfly) and size (Large: motorbike, cow; Small: roller-skate, butterfly) dimensions under four task conditions comprising conceptual (naturalness, size) and …

Octopus Sentience: Three Criteria, Alix Noël-Guéry

Animal Sentience

The first question to ask is whether octopuses are sentient, so that, if so, they can be protected. Three consensual criteria to evaluate animal sentience can be applied to the octopus. Octopuses meet all three of them.

Reconciling Just Preservation, Shelley M. Alexander

Animal Sentience

Treves et al.’s target article can play an important role in reconciling the needs of future generations and non-human animals in conservation. Human capacities are adequate for interpreting and defining many non-human animal needs. Worldviews are more complex, however, and conservation science, like the target article itself, suffers from a lack of diversity and inclusiveness. This may pose practical impediments to realizing just preservation.

The Mental Lives Of Sheep And The Quest For A Psychological Taxonomy, Carrie Figdor

Animal Sentience

Research into nonhuman cognition has broadened and deepened in recent years. It supports and motivates a shift toward an ecological rather than an anthropocentric approach to cognition.

Five-Minute Cognitive Test As A New Quick Screening Of Cognitive Impairment In The Elderly, Jie Zhang, Lijun Wang, Xia Deng, Guoqiang Fei, Lirong Jin, Xiaoli Pan, Liuhan Cai, Anthony D. Albano, Chunjiu Zhong

Department of Educational Psychology: Faculty Publications

This study aims to develop a new evaluation method for quickly and conveniently screening cognitive impairment in the elderly. The five-minute cognitive test (FCT) was designed to capture deficits in five domains of cognitive abilities, including episodic memory, language fluency, time orientation, visuospatial function, and executive function. Subsequently, FCT efficiencies in differentiating normally cognitive ability from cognitive impairment were explored and compared with that of the Mini-Mental Status Evaluation (MMSE). Equipercentile equating method was utilized to create a crosswalk between scores of the FCT and MMSE. Further, the association of scores of the FCT and MMSE with hippocampal volumes was …

How People Make Sense Of Drones Used For Atmospheric Science (And Other Purposes): Hopes, Concerns, And Recommendations, Janell C. Walther, Lisa M. Pytlikzillig, Carrick Detweiler, Adam L. Houston

Lisa PytlikZillig Publications

Unmanned aerial systems (UAS) can advance understanding of the atmosphere and improve weather prediction, but public perceptions of drone technologies need to be assessed to ensure successful societal integration. Our qualitative study examines public perceptions of UAS technology, and the associated risks and benefits, for such civilian purposes. We examine how people form perceptions, and discuss the implications of these perceptions for UAS design and regulation. Our study finds the public to be favorable toward UAS used for “noble” purposes. Participant views are informed by popular media, personal experiences, comparisons between technologies, and consideration of the trustworthiness of the users, …

Batman's Animated Brain(S), Lisa Kort-Butler

Department of Sociology: Presentations

Much of the analysis of Batman’s brain – whether by scholars, writers, or other comic characters – focuses on his psychological make‐up. That is, what makes Bruce Wayne psychologically motivated to be The Batman? His childhood trauma is often poised as the answer, the tireless pursuit of “justice” in an attempt to regain control from the trauma of his parents’ murders (Sanna 2015). The same could be said for his nemeses. Madness, psychopathy, and insanity are centered in the corrupted minds of Gotham’s ghastliest, some of whom have also had psychological or physical traumas (Langley 2012; Lytle 2008). A psychological …

Access To The Healthcare System For Acb People Living In Waterloo Region, Ontario: A Racial And Socio-Ecological Examination, Tiyondah Fante-Coleman

Theses and Dissertations (Comprehensive)

Little research has investigated the barriers and facilitators to accessing healthcare for African, Caribbean, and Black people in Canada. This thesis identifies barriers and facilitators using a socio-ecological framework in two papers. Five focus groups were held with 22 ACB participants in Waterloo, Ontario. Thematic analysis guidelines informed the analysis of focus group data. The first paper identified barriers at the social (racism and employment, immigrant status) and institutional (wait times, out-of-pocket expenses) levels. Community connections was the sole facilitator at the social level. The second paper identified four barriers at the interpersonal level: physicians’ style of care, lack of …

Connectedness To Nature And Pro-Environmental Behaviour From Early Adolescence To Adulthood: A Comparison Of Urban And Rural Canada, Daniel Anderson

Theses and Dissertations (Comprehensive)

Previous research has demonstrated that emotional connectedness to nature (ECN) is one of the strongest predictors of pro-environmental behaviour (PEB). This study investigated the influence of age, gender and living context on ECN and PEB in two Canadian samples.

Study participants completed an environmental survey, which assessed demographic data as well as their levels of ECN and PEB. Project I, which contained 1251 participants, investigated what group factors (age, urban vs. rural living context, male vs. female) contributed to ECN and PEB, as well as whether ECN mediated the relationship between age and PEB. Project II, which contained 84 adolescents, …

Helping Those Who Are Like Me: Highlighting Similarities To Elicit Empathy In Narcissists, Alys Yijun Zhao, Christian H. Jordan

Theses and Dissertations (Comprehensive)

Previous research suggests that narcissists (compared to less narcissistic individuals) lack empathy toward others unless specifically instructed to take others’ perspectives. But are narcissists capable of spontaneously empathizing with others without the need for instructed perspective-taking? Three studies addressed this question. Study 1 (Study 1a; N = 232 & Study 1b; N = 488) examined whether manipulating a target person’s level of narcissism (i.e., non-narcissistic, moderately-narcissistic, or highly-narcissistic) encouraged more empathy toward more narcissistic targets, who described a difficult romantic breakup, from more narcissistic participants. Study 2 (N = 590) used the same procedure and further examined whether target …

The Influences Of Culture And The Self On Children’S Memory Encoding And Delayed Retrieval, Hongyuan Qi

Theses and Dissertations (Comprehensive)

Culture and the self form a dynamic system that shapes children’s memories. However, how these two constructs influence specific memory processes still requires further investigation. The present dissertation contains four studies that examined the influences of cultural backgrounds and self-views on children’s memory encoding and delayed retrieval. Participants across four studies were recruited in the year range of 2016 to 2018. A total of 243 Grade 1 and 2 (the younger group) and Grade 3 and 4 (the older group) children participated, with an age range of seven to ten years.

Stress, Cognitive Distortions, Engagement In Self-Care, And Burnout In Psychology Graduate Students, Lauren Matturro

PCOM Psychology Dissertations

Psychology graduate students are tasked with finding a balance between academic responsibilities, clinical training, home life, time constraints, and financial concerns. These competing demands lead to stress, which is well documented in medical students with similar workloads, but understudied in psychology graduate students. Previous studies indicate that perceived stress can be linked to prevalence of an individual’s cognitive distortions. Additionally, stress within the human service fields often leads to burnout. Self-care is widely recognized as a preventative effort against developing burnout. However, as students have limited time, they may find engaging in self-care activities to be difficult. The purpose of …

Attraction Among Late-Adolescents, C. Nathalie Yuen, Tom Koziol, Jonathan Santo

Psychology Faculty Publications

Using a within-subjects experimental design, this study assessed the association between age and level of attraction in 514 male and female participants 19 years of age or older when rating photographs of individuals 19-22. The hypotheses were formulated to test the evolutionary perspective of attraction, that males prefer a younger female mate while females prefer an older male mate. Additionally, this theory suggests that initial attraction is influenced largely by reproductive factors. To test these hypotheses, 320 different pictures for each sex were used to measure perceived attractiveness. Multilevel modeling was used to test the proposed hypotheses which were partially …

Understanding Sexual Prejudice: The Role Of Political Ideology And Strategic Essentialism, Crystal L. Hoyt, Thekla Morgenroth, Jeni L. Burnette

Jepson School of Leadership Studies articles, book chapters and other publications

Despite the increased visibility and acceptance of the LGBTQ community, sexual minorities continue to face prejudice and discrimination in many domains. Past research has shown that this prejudice is more prevalent among those holding conservative political views. In two studies, we merge strategic essentialism and motivated ideology theoretical perspectives to empirically investigate the link between political orientation and sexual prejudice. More specifically, we examine how conservatives strategically use different forms of essentialism to support their views of gay individuals and their reactions to messages aimed at changing essentializing beliefs. In Study 1 (N = 220), we demonstrate that conservatives endorse …

Lifetime History Of Concussions And Behavioral Measures Of Anhedonia, John O'Donnell

Electronic Theses and Dissertations

Concussions are the most common neuropsychological problem in the United States and are associated with sequelae such as cognitive complaints and depression-related symptoms. Recent research suggests that head trauma is associated with anhedonia and that concussions have the potential to damage axons and postsynaptic connections in neural circuits that play a role in reward processing. Anhedonia may be better understood as an overarching construct with multiple subtypes including motivational, decisional, and consummatory. The current study examines the relationship between lifetime concussion history and subtypes of anhedonia using behavioral measures of reward processing: the Effort Expenditure for Rewards Task (EEfRT), Probabilistic …

If A Virtual Tree Falls In A Simulated Forest, Is The Sound Restorative? An Examination Of The Role Of Level Of Immersion In The Restorative Capacity Of Virtual Nature Environments, Jessica Michaelis

Electronic Theses and Dissertations

Stress and cognitive fatigue have become a pervasive problem, especially in Western society. Stress and cognitive fatigue can have deleterious effects not only on performance, but also on one's physical and mental health. This dissertation presents a study in which the aim is to investigate the effects of virtual nature on stress reduction and cognitive restoration. Specifically, this study assessed the effects of Immersion (Non-immersive, Semi-immersive, Fully-immersive) and Exploration (Passive vs Active) on stress reduction and cognitive restoration. Additionally, restoration from the most effective virtual nature environment was compared to that of taking an active coloring break. Eighty-three university students …

Temporal Dynamics Of Human Emotional Response To Aversive Stimuli, Joseph Lawence Kempel

Graduate Research Theses & Dissertations

Emotions are an integral part of human expression and are often communicated nonverbally through behavioral actions. With advancements in electroencephalography (EEG) technology it is now possible to measure the dynamics of emotion generation in an individual on the basis of patterns in their brain activity. This thesis aims to model the temporal dynamics of human emotion generation upon exposure to aversive stimuli and measure the effect of external distractions as a viable emotion regulation strategy.

This research builds on previous work in the literature that has shown that the ability of humans to regulate their emotions intrinsically (based on their …

The Development Of Scientific Reasoning: Children’S Evaluation Of Experiments And Evidence, Taneisha Vilma

Graduate Research Theses & Dissertations

This investigation examines scientific reasoning among elementary school students by assessing experiment and evidence evaluation. Previous studies have not fully distinguished these two abilities. The present study directly compared experiment and evidence evaluation within the same task and also examined the recognition of confounded variables.

Using a modified version of a science reasoning procedure, students in first-, third-, and fifth-grade (N = 54) were presented with two sets of problems: (a) 1-Variable problems examined recognition of the difference between conclusive and inconclusive tests, and (b) 2-Variable problems further assessed recognition that confounded variables make an experiment inconclusive. For the 1-Variable …

An Experimental Examination Of Intolerance Of Uncertainty In Obsessive-Compulsive Disorder, Hannah Faleer Martyn

Graduate Research Theses & Dissertations

Anxiety is considered a fear response to threat, driven by the absence of certainty and elevated perceptions of the cost of harm. It has been suggested that exaggerated responding to uncertainty underlies all anxiety disorders. Although no longer classified under the anxiety disorders section of the Diagnostic and Statistical Manual (DSM), anxiety still is considered a primary component of obsessive-compulsive disorder (OCD). OCD is a chronic, debilitating condition that affects multiple domains of functioning. The current gold standard of treatment for OCD is exposure and response prevention (ERP), a form of cognitive-behavioral psychotherapy. However, ERP is not effective for all …

The Role Of Sensory And Affective Systems In The Semantic Processing Of Abstract Concepts, Jane Elizabeth Neal

Graduate Research Theses & Dissertations

The role of modal, or embodied, systems in the semantic representation of abstract concepts, which are by nature not experienced by the senses, remains unclear. The experiments presented in this dissertation investigated the extent to which the activation of visual or affective systems may be modulated by context. Experiment 1 examined whether a verbal or visual memory load interfered with the semantic processing of abstract concepts paired with either a low or highly imageable adjective, and whether processing was similarly affected for concrete concepts. While the cognitive loads were effectively maintained, neither load type affected processing times for either concept …

This research addresses the use of canine animals in substance abuse treatment. There is research that addresses the importance of animals regarding therapy and mental illness, as well as research on the comorbidity of severe mental illness and substance abuse disorder. However, there is no research that looks at utilizing canines in substance abuse therapy. The purpose of this research was to examine the utilization of canine animals in rehab for those with substance abuse issues. The theoretical foundation for this study is the theory of contextualism. This theory focuses on humans with animals. To address the gap in research, …

Attention Deficit Hyperactivity Disorder And Psychopathy In The General Adult Population, Kathryn Richelle Wilson

Walden Dissertations and Doctoral Studies

Attention deficit hyperactivity disorder (ADHD) is one of the fastest growing mental disorders in the United States. More children are being diagnosed than ever before, and many of these individuals are finding that at least one other emotional, behavioral, or mental disorder often accompanies ADHD (including psychopathy). The number of individuals in the prison population with both ADHD and psychopathy is on the rise. Because of these increases, including what is being seen in the prison population, this study aimed to identify if there was a relationship between ADHD and psychopathy in the general population, and if there were specific …

An Exploration Of The Experiences Of Equine Therapy Specialists, Jaime Lyn Battestella-Williams

Walden Dissertations and Doctoral Studies

Horses have been an integral part of human history and progress for centuries. Horses and humans have united in diverse ways, including farming, war, construction, racing, and other areas of sports. Researchers have indicated that the use of horses for mental health and wellness is a growing trend that continues to lack strong, empirical evidence. Currently, there is limited research available on the experiences of certified equine specialists incorporating horses into mental health and wellness. It is essential to gain further insight into the incorporation of horses into psychology and counseling for therapists, as well as potential clients, interested in …
