Rapid Golgi Stain For Dendritic Spine Visualization In Hippocampus And Prefrontal Cortex, Maya Frankfurt, Rachel E. Bowman

Psychology Faculty Publications

Golgi impregnation, using the Golgi staining kit with minor adaptations, is used to impregnate dendritic spines in the rat hippocampus and medial prefrontal cortex. This technique is a marked improvement over previous methods of Golgi impregnation because the premixed chemicals are safer to use, neurons are consistently well impregnated, there is far less background debris, and for a given region, there are extremely small deviations in spine density between experiments. Moreover, brains can be accumulated after a certain point and kept frozen until further processing. Using this method any brain region of interest can be studied. Once stained and cover …

Third Culture Kids - Playing To Heal, Amna Sana

Theses and Dissertations

With increased globalization and a large expat population, Qatar is home to increasing numbers of Third Culture Kids (TCKs). TCKs are children who live in a country where their parents are non-native, children who grow up between cultures. Young TCKs, especially children between the ages of three and seven, do not possess the skills to adequately vocalize their feelings, but fortunately, play therapy allows them to articulate problems and feelings on their own terms. This thesis addresses the emotional hurdles facing TCKs, using concepts derived from play therapy and offering a series of interactive objects designed to reflect emotional expression …

The Role Of Memory-Based Processing And Coherence Building In Retrieval Interference, Ryan D. Kopatich

Graduate Research Theses & Dissertations

Characters in narratives often behave in ways that are inconsistent with their beliefs, values, and previous actions. What effect do these contradictions have on a reader’s memory of character’s prior beliefs? One model, the Knowledge Revision Components framework (KReC) argues that a passive memory-based process is responsible for reducing access to information that is no longer true (e.g., when a character who is afraid of heights gets help facing her fears, it is harder to recall that she was afraid of heights). This possibility is called the general interference hypothesis. Subsequent research on KReC has shown that this process only …

Exploring The Causal Role Of Inferences Elicited By Accompanying Text In Aesthetic Experiences, Christian C. Steciuch

Graduate Research Theses & Dissertations

Appreciating paintings has been shown to be partly based on the viewer’s knowledge of the artwork. One technique that provides background knowledge to viewers is through text that is shown alongside artwork. Knowledge of the artwork can also arise from inferential processes regarding the artwork. Relatively little research has explored the role of accompanying text and inferential processes on aesthetic responses. The current study assessed the causal role of accompanying text and inference-making across cognitive (e.g., understanding) and emotional (e.g., positive affect) aesthetic responses. It was hypothesized that aesthetic responses would increase with the amount of accompanying text paired with …

A Proposed Return-To-Ride Protocol For United States Jockeys Following Concussion, Carolina Quintana, Kimberly I. Tumlin, Matthew C. Hoch, Nicholas R. Heebner, Bianca L. Grimshaw, Carl G. Mattacola

Clinical Practice in Athletic Training

Professional horse racing jockeys participate in a high-risk sport, however there is limited research and policies regarding welfare and safety. Despite the high incidence and risk of concussions, there are not standardized protocols for returning these unique athletes to participation following concussion. A return-to-ride concussion protocol for thoroughbred horse racing athletes must take into account the unique considerations and practices of the sport. Current concussion management strategies suggest removal from riding and activity when a concussion is suspected. This is followed by further evaluation for diagnosis, a period of both cognitive and physical rest before a gradual return-to-activity prior to …

The Effect Of Test Difficulty On Perceived Memory Performance, Phoebe S. Bean

Graduate Student Theses, Dissertations, & Professional Papers

Neuropsychological testing is a critical element of the assessment and treatment of a host of neurological disorders, such as Alzheimer’s Disease, stroke, and traumatic brain injury. Certain non-neurological variables may also affect an individual’s test performance. Such secondary factors may include current psychiatric issues, chronic pain, sleep, and the effort put forth during testing. Little is known, however, about the effect the testing process itself has on people’s actual and perceived cognitive abilities. For example, the process of undergoing memory testing may, through a variety of mechanisms, influence memory performance and impact the person such that their view of their …

Examining The Impact Of Mental Health Education On Bias And Stigma In Cit Trained Officers, Jennifer L. Krause

Walden Dissertations and Doctoral Studies

The purpose of this quantitative, correlational nonexperimental research was to examine the relationship between the mental health education received through Crisis Intervention Team (CIT) training and the perceptions of public mental health stigma, self-stigma, and attitudes toward seeking mental health services among law enforcement officers. The study’s theoretical framework integrated gender-role conflict theory and Goffman’s stigma theory in explaining the influence of the police culture on officers’ adoption of more traditional masculine roles. This research used three instruments: the Attitudes to Mental Illness questionnaire to measure perceptions of public stigma, the Self-Stigma of Seeking Help Scale to measure self-stigma, and …

Using Chess As An Intervention To Improve Executive Functioning Among Youth, Anandita Oberoi

Walden Dissertations and Doctoral Studies

Youth represent a vulnerable segment of the population and may have underdeveloped levels of executive functioning (EF), which is important in both daily life and is shown to have far-reaching effects. This research study aimed to decipher if lessons in the game of chess could be used as an efficacious intervention for accelerating EF development in youth. The three research questions focused on determining whether there was a difference in the chosen indices of EF before and after a 14-session chess intervention. The theoretical framework used for this study was Piaget’s cognitive development theory. This quantitative, single group pretest–posttest design …

Differences In Attitudes Among Therapists In Suburban Versus Urban Settings Regarding Evidence-Based Treatments, Bennie Lamont Kyle

Walden Dissertations and Doctoral Studies

AbstractPrevious research has indicated that evidence-based treatments have proven effective in clinical trials. However, the transfer of desired outcomes from research settings to practice settings reflects a gap in the literature. Therefore, the purpose of this study was to examine whether differences exist between the attitudes of therapists who work in suburban versus urban settings and who do and not use evidence-based treatments in their attitudes toward evidence-based treatments and perceptions of treatment characteristics. The theoretical framework for this study was the theory of planned behavior. This quantitative study used the evidence-based practice attitude scale to assess therapist attitudes toward …

Chronic Pain, Malingering, And The Word Memory Test, Dawn Marie Emmett Bishop

Walden Dissertations and Doctoral Studies

AbstractThe importance of using scientifically grounded strategies to detect malingering has been established in the literature and past research. Many reliable tools have been established for the detection of malingered neurocognition; however, research on how pain may affect these tools is sparse. The purpose of this study was to investigate the effect of pain on cognitive symptom validity testing and to establish the validity of the Word Memory Test (WMT), a cognitive symptom validity test with good sensitivity and specificity, when the test taker is feigning pain (simulating) or remembering pain. The biopsychosocial model and the gate theory of pain …

The Relationship Between Programming After Critical Incidents, Shootings, And Resilience In Police, Michelle Lise Vincent

Walden Dissertations and Doctoral Studies

AbstractThe purpose of this study was to examine whether there was a relationship between resilience, posttraumatic growth, and reintegration programming after a critical incident and/or line of duty shooting through the cognitive, self-efficacy and resiliency theoretical lenses. The research aimed to determine if police officers, who participated in reintegration programming, specifically in this study, Edmonton Police’s Reintegration After Critical Incident programming, produced higher scores in resilience as measured on the Connor-Davidson Resilience Scale (CD-RISC) and posttraumatic growth, as measured on the Post Traumatic Growth Inventory scale (PTGI), with Canadian police officers compared to police officers who do not participate in …

Mental Health Provider Experiences Among Juvenile Offenders With Attention Deficit Hyperactivity Disorder, Vanessa West

Walden Dissertations and Doctoral Studies

Research has indicated various treatment options available such as medication management or family therapy for juvenile offenders struggling with a diagnosis of, or symptoms of, attention deficit hyperactivity disorder (ADHD). Exploring mental health clinicians’ perceptions may provide insight into treatment needed for this population to contribute positively to society. Past researchers refrained from obtaining mental health clinicians’ perspectives on treatment when working with this population. Rational choice theory indicates that individuals examine the costs and benefits of their actions prior to making decisions. Gestalt/feature-intensive processing theory promotes the inclusion of necessary information to help with processing when making decisions. Youth …

Data Modeling Of Cognitive Structure In Physiotherapy Students Learning Gross Anatomy, William Allan Besselink

Walden Dissertations and Doctoral Studies

Cognitive structures that promote deep learning of gross anatomy are integral to musculoskeletal physiotherapy practice yet poorly understood. This quantitative, criterion-related validation study addressed two data modeling strategies (multidimensional scaling and Pathfinder networks) as a potential visual and quantitative representation of the cognitive structures of physiotherapy students learning gross anatomy. The study was grounded in the Adaptive Control of Thought-Rational theory of cognition. The research questions addressed the agreement (reliability, accuracy, and association) between student and expert cognitive structures and included the derived quantitative parameters as predictor variables in multiple regression to examine potential relationships with unit grades. An online …

Integration Of Morphine And Virtual Reality: Pain Management For Adult Hospice Cancer Patients, Arlisa Hurd

Walden Dissertations and Doctoral Studies

There is currently a problem in that cancer patients engaging in hospice may experience an excessive amount of perceived pain and a decreased quality of life. The purpose of this study was to explore an intervention that could lessen the perceived pain experienced by, and increase the quality of life of, cancer patients engaging in hospice. Immersion music virtual reality (IMVR) allows a user to interact with a realistic, computer-generated environment. 3D music (IMVR) is likely suited for pain management with patients in hospice and was used for this study. The theory for the study is the gate control theory. …

Memory Strategy Instruction With Goal-Setting And Positive Feedback: Impact On Memory, Strategy Use, And Task Commitment, Mercedes E. Ball

University of the Pacific Theses and Dissertations

Strategy instruction can improve memory performance, but some training programs are more effective than others. Some scholars propose that a key element to boosting the benefits from training programs is enhancing or emphasizing self-regulatory factors, such as knowledge about memory, beliefs about ability, or motivational factors. Research supporting this claim evidence adds that programs that enhance trainees’ confidence in their abilities improve memory performance and that multifactorial programs are more effective than strategy-training-only programs. Setting performance goals and receiving feedback are two self-regulatory factors known to relate to memory performance that may sometimes be included in some training programs. However, …

Influence Of Increased Options On Performance Generalization Across Two Variations Of The Monty Hall Dilemma, Robert A. Southern

College of Graduate Studies: Theses & Dissertations

The Monty Hall dilemma (MHD) is a probability puzzle at which humans consistently fail to adopt the optimal winning strategy. The participant chooses between three identical doors, behind one of which is a valuable prize. After the participant makes their initial decision, the host reveals that there is nothing behind one of the two remaining doors, then asks the participant if they would like to stay with their originally selected door or switch to the remaining unopened door. The optimal choice is to switch to the previously unchosen door, which increases the probability of winning from 33% to 67%. Despite …

Altering The Distance: Using Construal Level Theory To Examine Conciliatory Policy Support, Brandon Reinkensmeyer

Theses and Dissertations--Psychology

Distancing—a cognitive reappraisal strategy—increases conciliatory policy support (i.e., policies redressing inequity) by reducing anger. Related but distinct research has used construal level theory (CLT), which explains the relationship between psychological distance and mental representations (e.g., events and attitudes), to explore intergroup relations. CLT demonstrates increased psychological distance induces abstract thinking, which leads to high-level construal (HLC) mindsets. HLC mindsets, like distancing, decrease political polarization and prejudice toward out-groups. As both distancing (an appraisal technique) and HLC mindsets (a potential outcome of appraisal techniques) may decrease political polarization and prejudice toward outgroups, across two experiments, the present work investigated whether …

Video Meetings In A Pandemic Era: Emotional Exhaustion, Stressors, And Coping, Betty J. Johnson

Antioch University Dissertations & Theses

In the first quarter of 2020, societal upheavals related to the COVID-19 pandemic included employers’ work-from-home mandates and an almost overnight adoption of video meetings to replace in-person meetings no longer possible due to contagion fears and social distancing requirements. This exploratory study aimed to address, in part, the scientific knowledge gap about video meetings as a source of emotional labor. The study used mixed methods to explore three hypotheses concerning how the contemporary use of video meetings related to emotional exhaustion, stressors, and coping. Data were gathered through an online survey questionnaire. Emotional exhaustion, the dependent variable in the …

Holding On To Who They Are: Pathways For Variations In Response To Toxic Workplace Behavior Among U.S. Intelligence Officers, Greta Creech

Antioch University Dissertations & Theses

The U.S. intelligence community is a critical mission industry responsible for protecting lives and safety in ways that impact the global security environment. Research on the deleterious impact of toxic workplace behavior on other critical mission fields, such as health care and the U.S. military, is robust. However, intelligence scholars publishing within the unclassified arena have been silent on the phenomenon, how personnel respond to it, and how it may impact the intelligence function. This lack of scholarship has afforded an opportunity to understand what constitutes toxic behavior in the intelligence environment and how it may affect U.S. national security …

Investigating The Use Of Mental-State Talk In Parent-Child Joint Reminiscing And Storytelling On Children’S Source Monitoring, Holly Autumn Nelson

Theses and Dissertations (Comprehensive)

Source monitoring is the process of identifying and analyzing sources of information (Johnson et al., 1993). The ability to monitor source improves with age which places children at a greater risk for blending and misattributing information from different sources. Experiencing source confusions has academic, legal, and social implications, and thus understanding how source monitoring develops is important. Research exploring factors that impact source monitoring have predominantly focused on maturational aspects such as at which ages children learn to monitor source and neurological factors such as executive functioning. However, the impact of age and executive functioning may vary across the type …

Investigating The Inhibition Of The Return Of Attention In The Tactile Domain, Robert Plax

Theses and Dissertations (Comprehensive)

Purpose: The time-course needed to elicit tactile inhibition of return (IOR) has not been well-defined due to the paucity of research in this area especially studies investigating spatial discrimination. Reportedly tactile IOR uses higher-order mental representations to orient attention spatially yet the properties of low-level dermatomal maps may better account for how IOR orients tactile attention in space although its contribution is unclear. The present study sought to establish a time-course that evokes IOR in a unimodal tactile spatial discrimination task and decouples the contribution of the dermatome from higher-order representations. Methods: Two conditions containing distinct tactile cue-target paradigms designed …

How To Improve Dynamic Decision Making: Evaluation Of A Brief Training Program On Human Error, Yoannis Hermida

UNF Graduate Theses and Dissertations

Current work environments require leaders to make effective and sound decisions in unpredictable situations. How can leaders improve their dynamic decision-making (DDM) skills? The current studies explored the effects of a training program on improving DDM in two computer-simulated tasks with different task characteristics. This study was comprised of two experiments. The first experiment included 83 undergraduate students who independently managed a computer simulated chocolate factory (ChocoFine). The second experiment included 111 students who played the role of a fire rescue chief overseeing a forest fire (WinFire). Half of the participants in each simulation group received a brief training on …

Jurors' Perceptions Of False Confessions, Madison G. Gallimore

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study examined the effect of mock jurors’ perceptions of a defendant’s false confession vs. no confession (false confession presence), coercive interrogation techniques vs. panic-escape (false confession reason), and expert witness testimony vs. defendant explanation vs. expert witness testimony plus defendant explanation for his false confession (source). The four hypotheses and one research question pertained to main effects and interaction effects of false confession presence, false confession reason, and source (separately) and expert witness conditions combined on five outcome variables. Outcome variables were defendant’s guilt, trustworthiness, suggestibility, susceptibility to external influences, and juror’s likelihood of changing their verdict. Using Amazon …

Fostering Music Performers In The 21st Century: A Contemporary Professional Perspective Toward A New Curricular Agenda For Graduate Study In Music, Andre Januario

Graduate Theses, Dissertations, and Problem Reports (ETD)

What if the core curriculum for graduate students in music performance were designed to prepare students to succeed in the world of the Fourth Industrial Revolution?

This dissertation offers a hypothetical answer: a structured and systematic academic curricular framework for music graduate students of performance of concert music (especially those in terminal degrees, such as doctoral students), along with music instructors, professional music performers, school administrators, and college professors, seeking to prepare such students for achieving and maintaining a music career more in keeping with the current work environment, especially those skills demanded by the Fourth Industrial Revolution and the …

A Review Of The Effects Of Dietary Restriction, Dehydration, And Caffeine Withdrawal On Cognition: Implications For A Disabled Submarine Scenario, Sarah Chabal

Journal of Human Performance in Extreme Environments

In the event that submariners become trapped aboard a disabled submarine (DISSUB), they must perform a multitude of cognitively demanding tasks in order to maximize their likelihood of survival. During this time, submariners will also be forced to endure poor living conditions, including drastic changes to their nutrition. These nutritional changes have the potential to impair submariners’ cognitive functioning and affect operational performance, which could jeopardize survival; however, the effects of DISSUB nutrition on cognitive performance are not well understood. This review first describes the unique nutritional conditions that submariners will experience in a DISSUB scenario, including the change to …

Are Giant Pandas (Ailuropoda Melanoleuca) Averse To Inequity?, Miranda R. Trapani

Theses and Dissertations

Inequity aversion, a negative response to situations of unequal reward distribution, is a cognitive trait usually seen in social species. This capacity is thought to regulate cooperative relationships in intelligent, cognitively flexible animals. Giant pandas are a unique case in that wild populations are characterized as nonsocial, however captive populations are socially housed until sexual maturity. This allows for the study of a nonsocial species in a social context and thus the assessment of socio-cognitive flexibility across evolutionarily distant taxa. Here, we assessed whether the giant panda (Ailuropoda melanoleuca) displays inequity aversion by testing ten juveniles living at …

Variation In Personality Among Semi-Wild Myanmar Timber Elephants, Sateesh Venkatesh

Theses and Dissertations

This study examines two personality traits: exploration and neophobia, which could influence human-elephant conflicts. Thirty-one semi-wild elephants were tested over two trials using a custom novel puzzle tube containing three tasks and three rewards. Our studies show that elephants do vary significantly between individuals in both exploration and neophobia.

Examining The Association Between Trait Mindfulness And How Positively An Exercise Bout Is Remembered, Bree Geary

Psychology Theses and Dissertations

Introduction: Remembered affect is associated with future exercise behavior. Research suggests that trait mindfulness is associated with better emotion regulation, more positive affective memory of negative stimuli, and less rumination. Therefore, the purpose of this study was to examine the relation between trait mindfulness and remembered affect of an exercise bout. Methods: Undergraduate students from Southern Methodist University (N=94) completed baseline measures of trait mindfulness and physical activity, a 15-minute vigorous-intensity exercise bout, and post-exercise measure (remembered affect at 15 minutes post exercise session, 1-2 days post, and 1-week post). Multilevel modeling was used to test the association with remembered …

Measuring Intelligence With The Sandia Matrices: Psychometric Review And Recommendations For Free Raven-Like Item Sets, Alexandra M. Harris, Jeremiah T. Mcmillan, Benjamin Listyg, Laura E. Matzen, Nathan Carter

Personnel Assessment and Decisions

The Sandia Matrices are a free alternative to the Raven’s Progressive Matrices (RPMs). This study offers a psychometric review of Sandia Matrices items focused on two of the most commonly investigated issues regarding the RPMs: (a) dimensionality and (b) sex differences. Model-data fit of three alternative factor structures are compared using confirmatory multidimensional item response theory (IRT) analyses, and measurement equivalence analyses are conducted to evaluate potential sex bias. Although results are somewhat inconclusive regarding factor structure, results do not show evidence of bias or mean differences by sex. Finally, although the Sandia Matrices software can generate infinite items, editing …
