An Analysis Of Extended Strings Of Hits And Misses In A Mental Telepathy Task, Gregory R. Peck Jan 2018

An Analysis Of Extended Strings Of Hits And Misses In A Mental Telepathy Task, Gregory R. Peck

Masters Theses

The current study was designed to reanalyze archival data from the Eastern Illinois University parapsychology lab to determine the frequency of strings of hits and misses. Four datasets were included in the analyses, comprising a total of 348 participants. It was hypothesized that there would be more strings of hits and/or misses than expected by chance; there would be a difference between the number of strings of hits and the number of strings of misses; and participant scores on a 7-point belief in psi scale would be related to the frequency of hits and misses. Results indicated that no significant …

Subjective-Objective Discrepancies Among Patients With Sleep Complaints In The Patient-Centered Medical Home, Keri Bayley Jan 2018

Subjective-Objective Discrepancies Among Patients With Sleep Complaints In The Patient-Centered Medical Home, Keri Bayley

Electronic Theses and Dissertations

Sleep misperception – the discrepancy between objective and subjective measures of sleep – has been shown to be prevalent among patients with insomnia and may be a promising target for sleep intervention. This study examined sleep misperception in a diverse outpatient medical sample using consumer-grade wearable actigraphs (i.e., Fitbit Charge HR™). Forty-four self-identified problem sleepers aged 20 to 79 participated in the study. Participants completed sleep diaries for one week while also tracking their sleep using the Fitbit Charge HR™. After receiving a personalized sleep report based on these data, participants repeated another week of sleep assessment. Sleep misperception was …

Dissecting The Components Of Neuropathic Pain, Dale George Jan 2018

Dissecting The Components Of Neuropathic Pain, Dale George

Electronic Theses and Dissertations

Pain is a public health issue affecting the lives of nearly 116 million adults in the US, annually. Understanding the physiological and phenotypic changes that occur in response to painful stimuli is of tremendous clinical interest, but, the complexity of pain and the lack of a representative in vitro model hinders the development of new therapeutics. Pain stimuli are first perceived and transmitted by the neurons within the dorsal root ganglia (DRG) which become hyperexcitable under these conditions. It has now been established that satellite glial cells (SGCs) that ensheathe the DRG cell body actively contribute to this neuronal dysregulation. …

Attitudes Toward Anonymous Public Nudes, Marianna Wendt Jan 2018

Attitudes Toward Anonymous Public Nudes, Marianna Wendt

All Master's Theses

While technologically-mediated expressions of sexuality have been previously studied, there is very little research regarding anonymous public nudes (APNs). APNs are nude photographs which are taken or cropped so as not to include the face or other identifying characteristics, and posted on the Internet. This differs from sexting in that the photographs are meant to be seen by an audience of strangers online, rather than one or a few trusted individuals. The purpose of this study was to examine perceptions of APNs. Sixty-seven male and 160 female students over the age of 18 were recruited from Central Washington University to …

Gender Differences In Task Switching: An Event-Related Potential Study, Briana M. Bratcher Jan 2018

Gender Differences In Task Switching: An Event-Related Potential Study, Briana M. Bratcher

All Master's Theses

The current study examined the possible differences in several brainwaves and behavioral reaction times between males and females in relation to task switching. Previous research has shown gender differences in various aspects of cognition including task switching. Task switching refers to the ability to cognitively switch from processing one task to processing another, completely different task. The current study utilized a color-shape target switching paradigm and event-related potentials to analyze possible gender differences. The results of the study showed no gender differences in relation to reaction times, P2 and P3b brainwave latencies or amplitudes. However, the study found a difference …

Engaging Undergraduates In Comparative Psychology: A Case Study, Lauren Highfill, Deirdre Yeater Jan 2018

Engaging Undergraduates In Comparative Psychology: A Case Study, Lauren Highfill, Deirdre Yeater

Psychology Faculty Publications

With many comparative psychologists teaching at small colleges and universities where resources are limited, maintaining a traditional animal laboratory housing rats or pigeons is not realistic for many of these researchers. One way to overcome this lack of overhead costs and extensive lab space, is to forge collaborations with local zoos and aquariums. Zoo and aquarium research projects provide a way to examine a wide range of species, which is an important tenet within the field of comparative psychology. Furthermore, many undergraduates are innately attracted to the prospect of working with exotic animals. Here, we propose utilizing visitor behavior research …

Does Infant Negative Affect Moderate The Impact Of Parenting On Effortful Control? A Test Of The Differential Susceptibility Hypothesis, Anton Petrenko Jan 2018

Does Infant Negative Affect Moderate The Impact Of Parenting On Effortful Control? A Test Of The Differential Susceptibility Hypothesis, Anton Petrenko

Graduate Research Theses & Dissertations

Parenting and early temperament characteristics have previously been shown to impact development of children’s self-regulation, which is in turn linked to a variety of developmental outcomes. However, few studies have evaluated interactions between difficult temperament and parenting, and only four published studies have specifically tested whether infants’ difficult temperament serves as a maker of differential susceptibility to parenting on self-regulatory development. The current study evaluated whether infant negative affectivity (NA) serves as a marker of differential susceptibility to positive and negative parenting on levels of effortful control (EC) at 18 months, which is at an earlier time point than has …

The Role Of Contact And Empathy In Stigma Toward Individuals With Mental Illness Among Mental Health And Non-Mental Health Professionals, Quincy A. Knolhoff Jan 2018

The Role Of Contact And Empathy In Stigma Toward Individuals With Mental Illness Among Mental Health And Non-Mental Health Professionals, Quincy A. Knolhoff

Masters Theses

This study was designed to help identify the factors that predict people's stigmatized attitudes toward individuals with mental illness. Corrigan (2002) suggested that stigmatized beliefs about individuals with mental illness may be detrimental to the potential recovery of these individuals, their self-esteem, empowerment, and their integration into society. One factor that has been found to reduce this stigma is personal contact with mentally ill individuals (Corrigan et al., 2002). Additionally, research has shown that empathy and principled moral reasoning are negatively correlated with prejudice, or stigma (McFarland, 2010). The current study examined level of contact, employment in a mental health …

Social Anxiety And Problematic Drinking In College Students: Examining Potential Mediators, Carissa Gutsmiedl Jan 2018

Social Anxiety And Problematic Drinking In College Students: Examining Potential Mediators, Carissa Gutsmiedl

Masters Theses

Social anxiety and problematic drinking are among the most prevalent disorders present in the college population. Having one or both of these disorders while in college can be detrimental to academic performance and can increase dropout rates. Social anxiety has been found to precede problematic drinking in previous research. The purpose of this study was to help determine what variables may explain this relationship (i.e., mediators). The current study tested whether emotion regulation difficulties, drinking motives, alcohol outcome expectancies, and self-discrepancy mediated the relationship between social anxiety and problematic drinking among college undergraduates (N = 135). Results indicated that emotion …

Digit Ratio As A Predictor Of Risk Taking And Sensation Seeking Personality Traits And Behaviors, Hanna Elizabeth Hobson Jan 2018

Digit Ratio As A Predictor Of Risk Taking And Sensation Seeking Personality Traits And Behaviors, Hanna Elizabeth Hobson

Masters Theses

Digit ratio is the difference in length between the pointer finger and the ring finger on either hand. Commonly referred to as the 2D:4D ratio, this ratio is determined prior to birth, and serves as an indicator of prenatal hormone exposure. Digit ratio has been found to correlate with fundamental personality and behavior characteristics in adulthood. Digit ratio is also thought to be a determinate of sexual orientation in both men and women, but has been debated in the literature. This study examined multiple 2D:4D relationships. Men who were found to have a more masculinized (ie. lower) digit ratio had …

Is The Relationship Between College Drinking Behaviors And Social Anxiety Mediated By Alcohol Expectancies And Traumatic Life Experiences?, Cortney Lin Kingsmill Jan 2018

Is The Relationship Between College Drinking Behaviors And Social Anxiety Mediated By Alcohol Expectancies And Traumatic Life Experiences?, Cortney Lin Kingsmill

Masters Theses

The relationship between alcohol consumption and social anxiety is difficult to understand, as there have been mixed findings in the research. In general, a positive correlation has been found between the two, with a focus on the mediating effect of alcohol outcome expectancies. Both positive expectancies and trauma have been correlated positively with social anxiety and drinking behavior. This paper reviews the literature and examines the relationship between social anxiety and alcohol consumption. A mediated model between these two variables with the mediators being alcohol expectancies and traumatic experiences was proposed, but this model did not fit the date. Specifically, …

Linguistic Correlates Of The Quiet Ego In Narratives About The Self, Katherine Maurer Jan 2018

Linguistic Correlates Of The Quiet Ego In Narratives About The Self, Katherine Maurer

Masters Theses

Increasingly, research has shown that the drive to elevate the self and the excessive pursuit of self-esteem have negative effects on well-being and mental health. In addition, many of the defensive and aggressive tendencies seen in psychological research can be seen as efforts to defend and elevate the self. In contrast to these tendencies, the quiet ego construct describes a state of ego balance characterized by an inclusive sense of identity, perspective-taking, detached awareness (mindfulness), and growth orientation. The quiet ego and related qualities have been associated with many positive outcomes. A body of research using the Linguistic Inquiry and …

Effects Of Task Goals On Processing Causal Explanations In Science Texts, Kathryn E. Rupp Jan 2018

Effects Of Task Goals On Processing Causal Explanations In Science Texts, Kathryn E. Rupp

Graduate Research Theses & Dissertations

Previous research has shown that students experience difficulty understanding scientific texts that explain physical systems (e.g., how coral bleaching occurs; how speakers work). Explanatory texts about physical systems depict causally connected components and events that change across time and space. Readers incrementally build a mental representation of the system often called a mental model. The primary goal of the present experiment was to explore the possibility that one reason why explanatory texts are difficult to comprehend is that students adopt reading goals that do not facilitate the construction of a coherent mental model of the explanation. In the present experiment, …

Tracing The Evolution Of The Tarasoff Duty In California, Benjamin A. Swerdlow Jan 2018

Tracing The Evolution Of The Tarasoff Duty In California, Benjamin A. Swerdlow

The Journal of Sociology & Social Welfare

Since the first Tarasoff decision in 1974, the question of mental health professionals’ “duty to protect” third-parties has been a topic of vigorous debate. The ensuing forty-three years witnessed considerable shifts in the statutory and legal landscape in the United States, including several significant changes in California state law over the past decade alone. In this historical review, I trace the evolution of the Tarasoff duty with a specific focus on the state in which that duty originated, California, with the intention of elucidating the major policy, ethical, and practical questions that have followed in the wake of the Tarasoff …

College Student Alcohol Use And Engagement In Prevention Programming, Alexis H. Branch, Shimona Kumar, Christina Mcgrath Jan 2018

College Student Alcohol Use And Engagement In Prevention Programming, Alexis H. Branch, Shimona Kumar, Christina Mcgrath

UROP Posters

Social problems and adverse consequences have been associated with risky alcohol use (Paschall et al, 2015). Personalized Normative Feedback (PNF) has been utilized to address these problems (White and Hingson, 2014) by comparing students’ alcohol use to campus or national norms (Butler et al, 2009). The current investigation sought to understand differences in alcohol use behaviors in freshmen who did and did not report completion of a personalized feedback intervention (PFI) in a diverse sample of college students from the Spit for Science (S4S) project. S4S is a campus-wide, longitudinal study on the genetic and environmental factors that contribute to …

Adolescent Expressive Reluctance Exacerbates Risk For Substance Use Following Daily Hassles, Chad M. Hensberger, David W. Sosnowski M.S., Wendy Kliewer Ph.D, Kristina Mcguire M.S. Jan 2018

Adolescent Expressive Reluctance Exacerbates Risk For Substance Use Following Daily Hassles, Chad M. Hensberger, David W. Sosnowski M.S., Wendy Kliewer Ph.D, Kristina Mcguire M.S.

UROP Posters

Previous research has established a link between adolescent’s perceived daily hassles and subsequent adjustment, but less is known about factors that exacerbate this relationship. The purpose of the present study was to identify if adolescent’s reluctance to express emotions moderated the association between their perceived daily hassles and subsequent substance use (i.e., alcohol, marijuana, tobacco). Cross-sectional data were obtained from a larger study that examined the effects of exposure to community violence among low-income, urban adolescents (N = 260, Mage = 14.14, SD = 1.62 years; 92% African American; 54% female). Linear regression analyses controlling for adolescent age, …

Effects Of Chemogenetic Inhibition Of Dopamine Transporter- Or A2a-Expressing Neurons On Spontaneous Activity And Motivation To Consume A Palatable Food Reward, James D. Wherry Jan 2018

Effects Of Chemogenetic Inhibition Of Dopamine Transporter- Or A2a-Expressing Neurons On Spontaneous Activity And Motivation To Consume A Palatable Food Reward, James D. Wherry

Graduate Dissertations and Theses

Dopamine (DA) transmission in the striatum influences the motivated pursuit of rewarding stimuli. Pharmacological and opto- and chemo-genetic studies have suggested that the release of DA onto D2+/A2A+-expressing striatopallidal neurons, plays a role in this process. To determine the potentially dissociable roles of DA-releasing ventral midbrain and striatopallidal neurons on motivational processes, we employed double transgenic mice that expressed inhibitory DREADDs—designer receptors that are activated only by otherwise inert ligands—only in dopamine transporter (DAT) or A2A adenosine receptor (A2A) expressing neurons, allowing us to transiently inhibit either DA-releasing neurons (DATcre/DREADD) or striatopallidal neurons (A2Acre/DREADD) during various tests. In the first …

Heritable Variation In Reward Sensitivity And Impulsive Cction And Choice In A Genetically Diverse Inbred Mouse Panel, Lauren S. Bailey Jan 2018

Heritable Variation In Reward Sensitivity And Impulsive Cction And Choice In A Genetically Diverse Inbred Mouse Panel, Lauren S. Bailey

Graduate Dissertations and Theses

Research in animal models and human subjects points towards reward sensitivity and impulsivity as being characteristics that predict greater positive subjective responses to stimulant drugs. The Collaborative Cross (CC) recombinant inbred mouse strains and their inbred founders are a powerful genetic reference panel that has potential as a tool for revealing genetic correlations. The CC/DO founder strains were used to examine the heritability of reward sensitivity and impulsivity traits. Founder strains were tested for activity in an open field, reward sensitivity, and reversal learning (impulsive action) or delay discounting (impulsive choice). Significant heritability for anticipatory responding within the reversal task, …

Analyzing The Use Of Expressive Writing Among College Students, Grace Ann Wilbanks Jan 2018

Analyzing The Use Of Expressive Writing Among College Students, Grace Ann Wilbanks

Honors Theses

This is among the first studies to investigate the naturalistic use of expressive writing in college students. To do so, 255 undergraduate students from the University of Mississippi anonymously completed an online survey. Participants first answered basic demographic questions followed by questions assessing their sadness or depression, happiness, and overall adjustment in college. Next, participants responded to questions concerning expressive writing and ways in which they handled demands of college. Finally, respondents then completed a well-researched, standardized measure of depression, anxiety, and stress. Independent-samples t tests revealed that students who engaged in expressive writing demonstrated lower mean levels of sadness …

Extraversion And Person-Environment Fit: Towards Consideration Of Jungian Theory In Organizational Psychology, Nicholas Rosemarino Jan 2018

Extraversion And Person-Environment Fit: Towards Consideration Of Jungian Theory In Organizational Psychology, Nicholas Rosemarino

Theses and Dissertations

Historically, the field of Industrial/Organizational (I/O) Psychology has relied on the Big 5 taxonomy of personality. The purpose of this study was to examine the value of a Jungian conception of extraversion in the context of the relationship between the physical work environment and person-environment (PE) fit. The MBTI and the NEO-IPIP, representing a Jungian and a taxonomic conception of personality, respectively, were hypothesized to predict the within-person relationship between extraverted environment and PE fit. PE fit was hypothesized to predict perceived satisfaction and perceived performance. To examine these hypotheses, 110 participants were recruited from Mturk and responded to 18 …

Influence Of Poverty, Parental Substance Use, Ethnicity, And Employment On Reactivation Following Family Reunification, Judith Anne Cornell Jan 2018

Influence Of Poverty, Parental Substance Use, Ethnicity, And Employment On Reactivation Following Family Reunification, Judith Anne Cornell

Walden Dissertations and Doctoral Studies

The maltreatment of children impacts individuals, communities, states, and societies. One response to the problem is the removal of children from their families, which can cause significant trauma for all involved. Moreover, the financial, legal, and emotional costs increase exponentially when subsequent re-removal, known as reactivation, occurs. Nationwide, the rate of reactivation averages just over 6%; in Arizona, the rate is significantly higher, with 11% of children being reactivated within 2 years of initial reunification. The purpose of this quantitative, non-experimental study was to determine whether poverty, ethnicity, parental substance use, parental employment, marital status, and number of children in …

Seeking Health Information In The Diabetes Online Community (Doc); The Role Of Health Literacy, Social Support And Community Interaction On Treatment Adherence, Allyson Hughes Jan 2018

Seeking Health Information In The Diabetes Online Community (Doc); The Role Of Health Literacy, Social Support And Community Interaction On Treatment Adherence, Allyson Hughes

Open Access Theses & Dissertations

Social support, being valued and cared for by others (Wills, 1991), is a critical construct for disease management and often includes providing advice and information to peers online. Approximately 83% of individuals with chronic disease search for health information online and there are more than 500,000 active social media users in the Diabetes Online Community (DOC) who have varying levels of disease management expertise. Due to the strenuous nature of Type 1 Diabetes (T1D), members of the DOC are continuously asking for and receiving anecdotal health information, yet very few studies have evaluated the impact of the DOC on treatment …

The Role Of Emotion Regulation Difficulties In The Connection Between Childhood Emotional Abuse And Borderline Personality Features, Lia Rosenstein, William D. Ellison, E. Walsh, Iwona Chelminski, Kristy Dalrymple, Mark Zimmerman Jan 2018

The Role Of Emotion Regulation Difficulties In The Connection Between Childhood Emotional Abuse And Borderline Personality Features, Lia Rosenstein, William D. Ellison, E. Walsh, Iwona Chelminski, Kristy Dalrymple, Mark Zimmerman

Psychology Faculty Research

In the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services project, we examined the role of emotion dysregulation as a mediator between childhood abuse and borderline personality disorder (BPD) feature severity among a sample of 964 adults presenting for treatment at an outpatient clinic. A structural equation model suggested that emotional abuse relates to BPD features both directly and through difficulties with emotion regulation, whereas physical abuse showed only a weak indirect relation with BPD features. There was no link between sexual abuse and BPD feature severity in the model. Results add specificity to etiological …

Fluoxetine Exposure Results In Decreased Sensitivity To Cocaine And Sucrose Later In Life: A Study In Female C57bl/6 Mice, Francisco Javier Flores Ramirez Jan 2018

Fluoxetine Exposure Results In Decreased Sensitivity To Cocaine And Sucrose Later In Life: A Study In Female C57bl/6 Mice, Francisco Javier Flores Ramirez

Open Access Theses & Dissertations

Preclinical evidence indicates that exposure to psychotropic medications, during early development, results in long-lasting altered responses to stress- and reward-related stimuli. However, these animal studies have been conducted, primarily, using male subjects. This is surprising, given that clinical data suggests that females have a higher likelihood, than their male counterparts, to be diagnosed with mood-related illnesses, and thus, be prescribed with psychotropic medications, mostly antidepressants. Therefore, to examine whether enduring reward-related alterations are exhibited as a result of antidepressant exposure, in female subjects specifically, we exposed C57BL/6 female mice to fluoxetine (FLX; 250 mg/l in their drinking water). Specifically, separate …

Epigenetic mechanisms result in persistent changes at the cellular level that can lead to long-lasting behavioral adaptations. Nucleosome remodeling is a major epigenetic mechanism that has not been well explored with regards to drug-seeking behaviors. Nucleosome remodeling is performed by multi-subunit complexes that interact with DNA or chromatin structure and possess an ATP-dependent enzyme to disrupt nucleosome-DNA contacts and ultimately regulate gene expression. Calcium responsive transactivator (CREST) is a transcriptional activator that interacts with enzymes involved in both histone acetylation and nucleosome remodeling. Here, we examined the effects of knocking down CREST in the nucleus accumbens (NAc) core on drug-seeking …

Nutrition Label Accuracy And The Theory Of Triadic Influence: The Impact Of Knowledge On Healthy Food Choices In A Predominantly Hispanic Sample, Mosi Staudt Dane'el Jan 2018

Nutrition Label Accuracy And The Theory Of Triadic Influence: The Impact Of Knowledge On Healthy Food Choices In A Predominantly Hispanic Sample, Mosi Staudt Dane'el

Open Access Theses & Dissertations

Unhealthy food choices and the outcomes of those choices are a significant concern in the United States. Multiple governmental agencies recommend using nutrition labels to promote healthier food choices. This study investigated this claim using the theory of triadic influence to examine the efficacious use of nutrition labels on food choices. The theory of triadic influence presents a model of variables that affect food choice, including knowledge pathways on which this study focuses. Within the model, we expected increased scores on two measures of health knowledge to predict nutrition label understanding, which predict healthy food attitudes. Next, we expected that …

Attitudes Of Clinical Psychologists Towards The Reporting Of Nonhuman Animal Abuse, Laetitia Geoffroy-Dallery Jan 2018

Attitudes Of Clinical Psychologists Towards The Reporting Of Nonhuman Animal Abuse, Laetitia Geoffroy-Dallery

Antioch University Dissertations & Theses

Research consistently demonstrates that nonhuman animals are capable of cognition and complex emotions, but their legal status in the United States remains similar to that of property. As such, they are not protected under laws mandating psychologists to report suspicions of abuse of populations that are judged to be vulnerable and unable to protect themselves, such as children, the elderly and people with disabilities (American Psychological Association [APA], 2010). Findings from previous research suggest that animal abuse is a relatively common topic encountered in therapy and the majority of clinicians are in favor of allowing voluntary reporting of nonhuman animal …

Delirium Predicts Three-Month Mortality In Critically Ill Patients: A New Model, Katharine E. Hartnack Jan 2018

Delirium Predicts Three-Month Mortality In Critically Ill Patients: A New Model, Katharine E. Hartnack

Antioch University Dissertations & Theses

Delirium is a neurocognitive disorder defined as an acute disturbance in attention, awareness, and cognition with a fluctuating course not better explained by a preexisting condition (American Psychiatric Association, 2013). It is prevalent in up to 70% of hospital patients and 82% of patients in the intensive care unit (ICU; Ely, Speroff, Gordon, & Bernard, 2004; Kavanagh & Gottfried, 2007; Mcnicoll, Pisani, Ely, Gifford, & Inouye, 2005). The impact of delirium on mortality is inconsistent in the literature. Many studies have concluded that delirium prevalence is associated with increased risk of mortality (Cole, 2004; Kavanagh & Gottfried, 2007; Moskowitz et …
