Immersive Cultural Plunge: How Mental Health Trainees Can Exercise Cultural Competence With African American Descendants Of Chattel Slaves A Qualitative Study, Clandis V. Payne

Antioch University Dissertations & Theses

This qualitative study utilized ethnographic techniques to explore the potential for change in mental health trainees resulting from the participation in an in vivo Immersive Cultural Plunge (ICP) within the African American Descendant of Chattel Slave community. The ICP combined Multicultural Immersions Experiences (MIE) of Cultural Immersion (CI) and Cultural Plunge (CP) to contribute to the developing body of research utilizing MIEs that incorporate contextual, experiential, and historical knowledge to teach the skill of cultural sensitivity. During the 12- hour ICP the participants experienced an orientation, a lecture, a tour/community interaction, a multimedia presentation within an African American community. In …

Reconsolidating: The Effect Of Spatial Context And Expectations, Chris R. Kiley

UNLV Theses, Dissertations, Professional Papers, and Capstones

Consolidation is the process by which memories become stable over time. Accessing a previously consolidated memory trace brings it back into a labile state where it must then undergo a re-stabilization process known as reconsolidation. During this process memories are again susceptible to interference and may be updated with new information. Reconsolidation has been demonstrated in animals as well as in the procedural and episodic human memory systems. The exact boundary conditions for reconsolidation are not yet known. Some studies suggest that reconsolidation is only necessary when new information is presented in a spatial context that is indistinguishable from the …

Nonmonotonicity In Absolute And Relative Preferences For Real And Imagined Rewards, Nicholas Carfagno

UNLV Theses, Dissertations, Professional Papers, and Capstones

A key assumption in many studies examining valuation of reward is that participants’ preferences for various rewards are meaningfully, monotonically ordered with respect to other possible rewards. However, this assumption has not been systematically tested. Two studies consisting of 74 undergraduates from the University of Nevada, Las Vegas and 122 community members demonstrated nonmonotonic reward preferences when provided with parametrically varied reward magnitudes. Although deficits in reward processing are believed to be a key feature of depression, depressed participants were more willing to work hard for rewards and exhibited more monotonic reward preferences than non-depressed participants. Relative to imaginary rewards, …

The Relationship Between Mood And Implicit Learning, Kathleen Larson

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation investigates whether a person’s current mood state influences their ability to learn implicitly. Implicit learning refers to learning about regularities in the environment without having conscious access to the information (e.g., Reber, 1967). According to the affect-as-information hypothesis, a positive mood increases global processing of incoming information and negative mood leads to local processing (e.g., Clore & Storbeck, 2006); however, most previous studies that investigated mood and cognition have focused on more explicit types of learning and decision making, but few have examined implicit processes. Thus, the current experiments examined how varying levels of mood and arousal affect …

Replicability And Reproducibility In Comparative Psychology, Jeffrey R. Stevens

Jeffrey Stevens Publications

Psychology faces a replication crisis. The Reproducibility Project: Psychology sought to replicate the effects of 100 psychology studies. Though 97% of the original studies produced statistically significant results, only 36% of the replication studies did so (Open Science Collaboration, 2015). This inability to replicate previously published results, however, is not limited to psychology (Ioannidis, 2005). Replication projects in medicine (Prinz et al., 2011) and behavioral economics (Camerer et al., 2016) resulted in replication rates of 25 and 61%, respectively, and analyses in genetics (Munafò, 2009) and neuroscience (Button et al., 2013) question the validity of studies in those fields. Science, …

Psychophysical Analysis Of Three Separate Anisotropic Patterns In Vision : Putting Visual Reference Frames In Conflict To Study The Class 1 And 2 Oblique Effects And The Horizontal Effect., Eleanor O'Keefe

Electronic Theses and Dissertations

This dissertation describes and investigates a debate about differences in the visual system’s anisotropic sensitivity to orientation as well as where and how the brain encodes visual orientation information. Three different visual perceptual patterns are discussed: the Class 1 and 2 oblique effects and the horizontal effect. The oblique effect is the ability to perceive cardinal orientations more easily than oblique orientations, and is found using narrowband stimuli. In the horizontal effect, oblique orientations are perceived most easily, horizontal orientations are perceived worst, and vertical orientations fall in-between, and is found using broadband stimuli. While the majority of authors refer …

Man/Boy., Nick Hartman

Electronic Theses and Dissertations

Verisimilitude, or the appearance of being true, is a concept I turn upside down; relating it to a guise I wear as a contemporary male in a society dictated by learned social behavior and gender norms. Cultural iconography and expected gender norms are tropes I confront within my artwork. Drawings of seemingly everyday objects act as meditations or a fetishized repetition of supposed unobtainable objects and ideals that deal with masculine societal norms. Manliness, machismo, masculinity… it is all a culturally learned and expected pose placed on all men. Coming to the realization that I do not necessarily fit …

The Influence Of Stimuli Proximity On Hedonic Context Effects, Christine Madurski

Theses, Dissertations and Culminating Projects

The context in which stimuli are presented can lead to hedonic judgments moving in two opposing directions. The movement of judgments toward the context is known as assimilation, and the movement of judgments away from the context is called contrast. Some factors that tend to lead to differences in these outcomes include whether the stimuli belong to the same category or not and if similarities or differences are made salient. The Gestalt principle of proximity may have the same effect as other grouping manipulations found in studies of hedonic context effects and cause people to perceive the context and target …

The Relationship Between Depressive Symptomology, Motivational Deficits And Striatal Activity In Traumatic Brain Injury (Tbi), Angela Spirou

Theses, Dissertations and Culminating Projects

Individuals with traumatic brain injury (TBI) have been shown to have high prevalence rates of depression. Reward processing and motivational deficits have been shown to be associated with depression, since both constructs rely on the ffonto-striatal network. In this study, we examined depressive symptomology, motivational tendencies and striatal activation during wins and losses in individuals with TBI. Participants (TBI and healthy controls [HC]) completed a gambling task composed of wins and losses in an MRI scanner. Depressive symptomology was assessed with the Chicago Multiscale Depression Inventory (CMDI), while motivational tendencies were assessed with the Behavioral Inhibition/Behavioral Activation (BIS/BAS) scale. Significant …

Stereotype Threat In Higher Education: The Role Of Psychological Capital On Student Satisfaction And Commitment, Lei J. Shirase

Graduate Theses/Dissertations

Stereotype threat refers to being at risk or confirming, as self-characteristic, a negative group stereotype about one's group. Past research has linked stereotype threat to a multitude of detrimental outcomes including decreased test performance, the drainage of cognitive resources, and increased stress levels. However, many of these findings were confined to laboratory settings and focused only on immediate effects. Research on stereotype threat framed as a macro-level product in a non-laboratory setting is limited at this time. In an attempt to bridge this gap, the present study examined the lingering effects of stereotype threat on minority satisfaction / commitment in …

Sexual Dimorphism In 2d:4d Digit Ratio Is Linked To Anxiety In Rhesus Macaques (Macaca Mulatta), Alexander Baxter, E. K. Wood, J. P. Capitanio, J. D. Higley

FHSS Mentored Research Conference

In humans, administering androgens exogenously reduces anxiety. Because prenatal androgen exposure (PAE) has organizational effects on the brain, and because it is higher in males, this may explain why, on average, females are more likely than males to develop anxiety. To assess PAE, the pointer-to-ring-finger digit ratio (2D:4D ratio) is frequently used. Though this phenotype is sexually dimorphic across primate species, preliminary research in a small number of species indicates that PAE's effect on digit ratio may be in the opposite direction when comparing nonhuman primates and humans. in humans, males typically show lower 2D:4D ratios than do females, whereas …

A Large-Scale Horizontal-Vertical Illusion Produced With Small Objects Separated In Depth, Z. Li, Frank H. Durgin

Psychology Faculty Works

We conducted two experiments (total N = 81) to investigate the basis for the large-scale horizontal-vertical illusion (HVI), which is typically measured as 15%–20% and has previously been linked to the presence of a ground plane. In a preliminary experiment, vertical rods of similar angular extents that were either large (4.5–7.5 m) and far, or small (0.9–1.5 m) and near, were matched to horizontal extents in a virtual environment by adjustment of horizontal gaps or rods. Large/far objects showed a larger HVI (∼13%) than did small objects (∼7%), as has been shown before, but the horizontal gap normally used to …

Bk Channels Mediate Synaptic Plasticity Underlying Habituation In Rats., Tariq Zaman, Cleusa De Oliveira, Mahabba Smoka, Chakravarthi Narla, Michael O Poulter, Susanne Schmid

Brain and Mind Institute Researchers' Publications

Habituation is a basic form of implicit learning and represents a sensory filter that is disrupted in autism, schizophrenia, and several other mental disorders. Despite extensive research in the past decades on habituation of startle and other escape responses, the underlying neural mechanisms are still not fully understood. There is evidence from previous studies indicating that BK channels might play a critical role in habituation. We here used a wide array of approaches to test this hypothesis. We show that BK channel activation and subsequent phosphorylation of these channels are essential for synaptic depression presumably underlying startle habituation in rats, …

My Story: A Doctoral Candidate's Journey, John D'Aguanno

CUP Ed.D. Dissertations

This study seeks to understand my doctoral journey. Meaning for my journey was drawn from the intersection of shared program experiences with 13 other study participants who had either already earned or were in the midst of retaining doctoral degrees of their own. Common thoughts, feelings, and behaviors associated with earning the doctoral degree were discovered during open-ended professional conversations centered on the framework of my research study: self-efficacy, motivation, perseverance or grit, and change or transformation. The shared description of my journey helped me understand my experience in a different more meaningful way. Through my narrative, I hope a …

Increasing Shared Attention In Children With Developmental Delays, Shelby Esman

Honors Theses

Joint attention behaviors may be essential to the development of language and social interaction skills (Whalen and Schreibman, 2003). Children with autism spectrum disorder (ASD) often lack these behaviors which may explain the difficulty many of them have communicating appropriately with others (American Psychiatric Association, 2013). Previous research has shown that prompting procedures and social reinforcement have been successful in teaching children with ASD to shift their eye gaze between an adult and the object of interest when prompted to do so (Taylor and Hoch, 2008). This present study set out to create and test a procedure designed to teach …

Teaching A Scanning Response To A Child With Autism, Katherine Burnham

Honors Theses

Children with autism have been known to exhibit abnormal scanning responses, or lack them entirely, as shown by the results of various studies (Sasson et al., 2008; Landry & Bryson, 2004). Studies have indicated that scanning may be a behavioral cusp and the lack of a normal scanning response in children with autism may be inhibiting the acquisition of many other subsequent skills (Bosch & Fuqua, 2001). By implementing an intervention to teach the scanning response, it was hypothesized that our participants would develop the prerequisite scanning skill, and therefore performance on a matching-to-sample procedure would improve. Through a basic …

Integrating Spatial Working Memory And Remote Memory: Interactions Between The Medial Prefrontal Cortex And Hippocampus, Ryan A. Wirt, James M. Hyman

Psychology Faculty Research

In recent years, two separate research streams have focused on information sharing between the medial prefrontal cortex (mPFC) and hippocampus (HC). Research into spatial working memory has shown that successful execution of many types of behaviors requires synchronous activity in the theta range between the mPFC and HC, whereas studies of memory consolidation have shown that shifts in area dependency may be temporally modulated. While the nature of information that is being communicated is still unclear, spatial working memory and remote memory recall is reliant on interactions between these two areas. This review will present recent evidence that shows that …

The Modulation Of Reward To Nicotine And Ethanol By Sex And Stage Of Exposure, Kyle L. Dixon

Psychology ETDs

Tobacco and alcohol are among the most widely used and abused drugs in America, resulting in disastrous health consequences and a massive resource drain on society. Nicotine (the primary reinforcing component in tobacco) and alcohol are often used together, though there is limited research on exposure to both drugs at the same time. The present study attempted to fill this gap in knowledge by examining the reward for a cocktail of nicotine and alcohol in male and female Long-Evans rats with differing histories of drug exposure. The conditioned place preference paradigm was used to examine the effects of sex as …

Functional Neural Connectivity Associated With Moral Processing In Healthy And Antisocial Samples, Samantha Jean Fede

Psychology ETDs

Although research finds that brain abnormalities during moral decisions underlie traits that lead to crime, understanding of these neural dynamics is limited. Here we use two samples to explore the role network engagement and components during moral processing. We used independent component analysis and functional network connectivity analysis to examine hemodynamic response during an fMRI task of moral processing. Eighty-four community and 539 incarcerated adult men and women participated; MANCOVA and machine learning algorithms were used to identify individual and group differences in both samples. We found patterns of neural engagement and connectivity consistent with proposed models of moral cognition …

Relationship Between Structure And Functional Connectivity Within The Default Mode Network, Andrei A. Vakhtin

Psychology ETDs

We proposed a novel measure of conceptualizing dynamic functional network connectivity (FNC) in the human brain using flexibility of functional connectivity (fFC), which captures the variance of functional connectivity across time. In task-free fMRI scans (N = 122), this measure was demonstrated to correspond to the underlying structural connectivity (SC) within the default mode network (DMN), while static functional connectivity (sFC) did so to a relatively low degree. As SC likely does not develop to facilitate task-free brain function, but rather to integrate information during cognitive engagement, we argue that fFC can estimate the potential functional connectivity exhibited outside of …

Social Risks As Costly Trait Signals, Ruth E. Sarafin

Psychology ETDs

Costly signaling theory posits that people will sometimes engage in seemingly irrational behavior to show off attractive qualities about themselves. These behaviors may end in or incur a cost to the actor such that only individuals who are highly fit are able to succeed at the behavior, and therefore behavior success is an honest signal of fitness. Previous research has used costly signaling to explain human physical risk taking behaviors such as rock climbing, but the current study seeks to apply them to social risk taking, such as raising one’s hand in class. Should social risk taking prove to be …

"Siren's Song of Sapiosexuality" by Emma Tabei

Abstract: Gender and male and female communications is discussed just as much if not more than politics currently. As we get more and more interested in understanding communication between genders, perhaps we need to look at where we came from instead of guessing what will happen next. Homer's, "Odyssey," specifically the "Siren's Song," pits male and female gender roles and perspectives against each other resulting in an untraditional look at modern female and male communications far ahead of Homer’s time; departing from the stereotypical gender looking glass. …

The Effects Of Comorbid Mild Traumatic Brain Injury And Alcohol Use Disorder, Brandi Seaman

Psychology ETDs

Objective: Sustaining a mild traumatic brain injury (mTBI) may influence alcohol consumption. The current study investigated the impact of self-reported mTBIs on alcohol use in a sample of individuals with alcohol use disorder (AUD) or a history of seeking treatment.

Participants and Methods: 173 individuals recruited for a neuroimaging/genetic study of alcohol abuse completed the Alcohol Use Disorders Identification Test (AUDIT) to assess consequences of consumption, and the Time Line Follow-back to assess average drinks per drinking day (DPDD). The Rivermead Concussion Scale was completed for each injury reported. The effects of the number of mTBIs (0,1, more than one) …

Framework For Ethical Decision Making: How Various Types Of Unethical Clothing Production Have Different Impacts On People, Ebru Pinar

Siegel Institute Ethics Research Scholars

The purpose of this study was to evaluate how various types of unethical clothing manufacturing impacts peoples’ shopping attitude in different ways. The study also focused on if there was an effect on how people decided what they find more important and if there was a change in their decision making after being informed. Using an online survey, Kennesaw State University college students, faculty, staff, and community members (n=78) were conducted randomly. As a result, Fair trade (p=0.032), Sweatshop or Child labor (p=0.007), and Sustainable Material (p=0.020) had statistically significant differences after being informed. …

Cognitive Maps Of Educators' Attitudes Toward Unauthorized Immigrants: A Multidimensional Scaling Perspective, Kerry Pecho

Theses and Dissertations

Legislative acts, political discourse, and social movements have highlighted how who immigrants are and where they are from play a substantial role in how they are received. Ewing (2012) noted that decisions regarding the U.S. immigration system are “often shaped more by public fears and anxieties than by sound public policy” (p. 2). The media often ignore the multiple challenges faced by immigrants and instead focus solely on their legal status (Nittle, 2012). Experiencing prejudice, on an individual and institutional level, has detrimental effects on the individual’s physical well-being, emotional well-being, and achievements and success in life. Research has indicated …

A New Rehabilitation Method For Stroke Patients: A Comparative Study Between The Pasta Matrix Reaching Task And The Novel Reaching Task, Shannon Maloney, Abigail Kerr, Faculty Advisor

John Wesley Powell Student Research Conference

Stroke is a leading cause of disability worldwide. To promote better outcome for stroke survivors, scientists use animal models to understand basic mechanisms of stroke, rehabilitation, and recovery. Rodent models have revealed that skilled reach training (e.g., coordinated use of digits and limbs) promotes improved functional outcome following stroke. The single-pellet task (SPT) is widely used in rats; however, it can be an insensitive measure in other species, such as mice. The pasta matrix task (PMT) has been effectively implemented in mice; however, the task is limited by its required strength component. This study introduces a novel-reaching task aimed at …

The Effects Of Studying Abroad On Second Language Acquisition, Laura Albert

Student Scholar Showcase

An increasing number of college students are participating in study abroad programs across the United States. The effectiveness of these study abroad trips on second language acquisition is an important topic for research. Previous studies have shown that there are differences for second language acquisition when it comes to the context of language learning (eg. classroom vs. abroad) as well as the duration of study abroad trips. The present study examined the effects of studying abroad versus formal classroom instruction on second language acquisition. In addition, the purpose of the study abroad trip was examined (e.g. learning Spanish, teaching ESL). …
