Continuous Theta Rhythm During Spatial Working Memory Task In Rodent Models Of Streptozotocin-Induced Type 2 Diabetes, Stephanie Hernandez, Ryan A. Wirt, James M. Hyman

McNair Poster Presentations

Alzheimer’s disease is a neurodegenerative disorder altering memory loss thought to be due to neuropathological symptoms such as the buildup of beta amyloid plaques (Ab) and neurofibrillary tangles (NFT). The etiology of Alzheimer’s is still unknown; however, potential risk factors such as diabetes may lead to its development. The most common form of diabetes is type 2 diabetes known for persistent insulin resistance leading to a state of hyperglycemia. Insulin resistance has been shown to affect cognitive abilities such as learning, memory and also alters synaptic plasticity. Neural connections between the hippocampus (HC) and anterior cingulate cortex (ACC) are known …

Anti-Queer Microaggressions Towards Queer Black Men, Camisha D. Fagan, Anna Smedley-López

McNair Poster Presentations

Microaggressions are reoccurring derogatory messages that degrade and/ or discredit one’s identity. While invisible and unknown to many, they remain visible and apparent to those impacted by them. The research questions for this project are: (1) What microaggressions do Queer Black men experience within larger society? (2) To contrast with larger society, what microaggressions do Queer Black men experience within Black communities? By conducting focus groups, I will examine the intersectional microaggressions that Queer Black males experience in their own community, as well as document microaggression that they experience in larger society. After conducting my focus groups, I will be …

Decoding The Neural Circuitry Of Reward Behavior, Ernesto H. Bedoy, James M. Hyman

McNair Poster Presentations

Classical conditioning demonstrates that rewards can be used to train behavior by pairing a stimulus, known as a prompt, with reinforced behavior. At a neuronal level, this association strengthens the connections between the neurons involved, making communication easier the next time. Enhanced communication is identified with learning, allowing an organism to anticipate a reward with a prompt so that it can perform the desired behavior to successfully obtain the reward (Noonan et al., 2011). In this study, we created a computational model to represent a neural circuit with synaptic plasticity during reward, no-reward and anticipation states. Our results confirmed our …

The Interaction Between Nicotine And Negative Symptoms In Schizophrenia And Bipolar Disorder, Bernajane Palisoc, Daniel N. Allen

McNair Poster Presentations

• Individuals with psychiatric conditions, such as schizophrenia (SZ) and bipolar disorders (BD), have a higher rate of smoking and have lower quit rates compared to the general population.
• As a dopamine agonist, nicotine may help alleviate negative symptoms by increasing abnormally low levels of dopamine in the prefrontal cortex and mesolimbic system consistent with the dopamine deficit hypothesis
• The purpose of the study is to further explore the interactions of nicotine and negative symptoms in a diverse population of individuals with serious mental illness.
• Furthermore, research examining interactions of nicotine and negative symptoms for individuals with schizophrenia compared to individuals …

Mrs. Agentic: Perceptions Of Women Who Sustain Their Birth Surname After Marriage, Ashley C. Lee, Rachael D. Robnett

McNair Poster Presentations

As more women earn higher education degrees every year, it is clear gender roles are becoming more egalitarian within Western society. More common than ever before, women are earning more degrees than men and are taking on different roles then what was once expected of them. With this new freedom, women have shifted from playing a supportive role within society to branching out and creating their own established identity. Not only are women maintaining a separate identity in the professional world, but they are also maintaining a separate identity in their marriages. Correlating with the increased number of women in …

Alzheimer’S In America: Effective Physical Activity Methods For Brain Health Reviewed, Royale Cannon, Laurel M. Pritchard

The alarming rise in rates of Alzheimer’s disease indicates that there is an immediate need for a solution. According to the Centers for Disease Control and Prevention (2014) Alzheimer’s is currently the sixth leading cause of death in the United States. Over 400,000 new cases are diagnosed each year and these numbers are only expected to rise (Centers for Disease Control, [CDC] 2014). One out of nine people are living with the disease and 84,000 people succumb to this disease every year in America; currently there is no cure or direct treatment plan for the disease (Alzheimer’s Association, [AA] 2010; …

Examining The Relationship Between Emotion Perception And Bullying: A Proposal, Marielle Leo, Kimberly A. Barchard

McNair Poster Presentations

Bullying and aggressive behaviors have adverse effects on many children. Violent behavior among children occurs most commonly in the school setting and may lead to negative emotional outcomes later in life (Kub & Feldman, 2015). According to a study conducted by Baroncelli et al. (2014), boys who have been found to be high in aggression have a difficult time perceiving relevant social cues such as fear and anger. However, boys were prone to frequently identify happiness and fear in faces when a different emotion was expressed. For girls, Baroncelli and colleagues did not find any significant relationships. The purpose of …

Stress And Coping In Women Of Color, Elizabeth Ochoa, Marya Shegog

McNair Poster Presentations

• Stress and coping research has identified stress and lack of coping mechanisms as contributors to the onset of chronic disease, as well as contributing to a low quality of life among women of color in comparison to their Caucasian counterparts (Mays, Yancey, Cochran, Weber, & Felding, 2002; Andrews, Felton, Wewers, & Heath, 2004).

• The research examining health disparities in African American women, a subset of women of color, have found that African American women do not have the effective skills to cope with stress, which may contribute to the onset of disease (Donovan & West, 2014; Woods- Giscombé, 2010; Mullings, …

A Computational Perspective Of Schizophrenia, Ernesto H. Bedoy, Geoff Powell, Jefferson Kinney

McNair Poster Presentations

The etiology of schizophrenia remains largely elusive, thus dampening the effectiveness of current treatment strategies. Abnormal neural migration and neurogenesis in the hippocampus have been suggested to be involved in schizophrenia (Jakob & Beckmann, 1994). A few approaches, including computational modeling, have investigated schizophrenia as a network disorder. Computational modeling uses mathematics to predict the behavior of biological systems based on the input of a set of parameters collected from laboratory experiments. In this study, we constructed a computational model to explore the ramifications of additional PV neurons migrating to an aberrant location in the hippocampus and interfering with a …

Modulatory Effects Of Gaba(B) Receptor Facilitation In A Model Of Chronic Inflammation, Michael A. Langhardt, Jefferson Kinney

McNair Poster Presentations

Inflammation within the brain (neuroinflammation) has been associated with a number of neurodegenerative diseases, including Alzheimerʼs disease (AD) (Solito et al., 2012). Within the brain, inflammation is defined broadly as prolonged activation of the brainʼs immune cells, known as glial cells. Excessive activation of glial cells within the brains of AD patients is a hallmark of the disease, however the mechanism by which this contributes to disease pathology is relatively unclear (Jo et al., 2014). Recently, studies have shown that glial cells, known as astrocytes, are able to synthesize and release the inhibitory neurotransmitter GABA (Charles et al., 2003). Further, …

Quality Of Peer Relationships Among Children With Selective Mutism, Marielle Leo, Rachele Diliberto, Christopher A. Kearney

McNair Poster Presentations

The current study examined the quality of peer relationships among children with selective mutism. Previous research suggests that children who are selectively mute have difficulty making friends and have poor outcomes in treatment. Participants were derived from the UNLV Child School Refusal and Anxiety Disorders Clinic. An initial assessment was conducted by the Clinic therapist. The study utilized a demographic form, the Child Behavior Checklist, and the Anxiety Disorders Interview Schedule—Parent Version. The current study found that children who are selectively mute ranged in the quality of friendships, and this knowledge may be used to help treatment outcome.

McNair Poster Presentations

This paper examined and synthesized the (limited) available literature on the pre-traumatic predictors of PTSD, specifically targeting populations in which traumatic events are experienced frequently because of the requirements of their positions, i.e., firefighters, police, and military personnel. A total of 21 articles were included in the final literature review and were used to assess the current available knowledge of the pre-traumatic traits of career-related PTSD, and address potential gaps in the literature. The culmination of this research was used to create specific risk profiles for each of the high risk careers included in this review, firefighters, police, and military …

Correlates Of Compulsive Buying, Brittaney Benson-Townsend, N. Clayton Silver

McNair Poster Presentations

Compulsive buying is a chronic issue for shoppers exacerbated by a nation obsessed with consumption. To predict compulsive buying behavior, a survey was administered to 283 college students in southern Nevada. The results suggested that the compulsive buyer exhibits am ex­ternal consumer locus of control and purchases goods with the intent to increase social status or quell anxiety. Given that responsible financial behavior changes as a function of age, college students are particularly vulnerable to compulsive purchasing behavior, as it is exacerbated by irresponsible credit spending behaviors.

Which Data Checking Method Is More Accurate?, Sarah Cobb, Kimberly A. Barchard

McNair Poster Presentations

Researchers use multiple methods for data checking. Each method can help identify and fix errors that were introduced during the data entry process. Fixing the errors that were introduced during the data entry process increases the accuracy of the research results. Accuracy is impor­tant because if a researcher publishes inaccurate results other researchers would not be able to replicate those results and draw the same conclusions. The purpose of this study is to compare the accuracy of four different data checking methods: double entry with one person, double en­try with two people, visual checking, and solo read aloud. So far, …

The Effect Of Experience On Infants’ Visual Preferences, Jennifer Bolick, Jennifer L. Rennels

McNair Poster Presentations

Research has shown that 3 to 4-month-olds with female primary caregivers show visual preferences for female relative to male faces (Quinn, Yahr, Kuhn, Slater, & Pascalis, 2002). Facial experience is likely an important influence on these preferences. From birth, infants’ experiences guide face processing skills. This processing ability influences the development of efficient face recognition later in life. The following study investigated (1) How visual pref­erences are influenced by real world experience with males and females, and (2) How experi­ence affects older infants’ visual preferences (i.e., 10-month-olds).

Effects Of Restraint Stress And Allopregnanolone Inhibition On Amphetamine Locomotor Sensitivity, Kelly Abuali, Laurel M. Pritchard

McNair Poster Presentations

The chronic, recurring nature of addiction remains a worldwide problem. Even after apparently successful clinical treatment and long term abstinence, individuals may still relapse many months or years later. Although many individual differences exist among substance abusers, relapse tends to occur during periods of high stress (Sinha et al., 2006). Behavioral training and therapy can help cope during these high stress times, but pharmacological interventions have not been shown to be effective (Ross & Peselow, 2009). Although some therapeutic options decrease relapse rates, more effective treatments for relapse need further consideration.

The effect of stress on use of and relapse …

An Acute Inflammatory Response In A Diabetic Alzheimer’S Disease Model, Krystal Courtney D. Belmonte, Jefferson Kinney

McNair Poster Presentations

Alzheimer’s disease (AD) is the most common form of dementia, accounting for 50 to 80 percent of all dementia cases. This neurodegenerative disease leads to neuronal death and tissue loss in the brain, resulting in the slow deterioration of memory, thinking skills, and eventually even the ability perform daily tasks. While it is not a normal part of aging, AD is mostly diagnosed in people over the age of 65; thus, the main risk factor for Alzheimer’s disease is increased age, though it is most likely other additional factors also contribute (Heese & Akatsu, 2006). Neuropathological hallmarks of AD include …

Ketamine Induced Deficits In Working Memory With Relevance To Schizophrenia, Michael A. Langhardt, Jefferson Kinney

McNair Poster Presentations

Schizophrenia is a chronic debilitating brain disorder, which affects approximately one per­cent of the adult population worldwide. The symptoms of schizophrenia are commonly divided into three broad classes: positive symptoms, negative symptoms, and cognitive disturbances (Kay, et al., 1987). The positive symptoms of schizophrenia include hallucinations, delusions, and dis­organized thinking, while the negative symptoms include affective flattening, social withdrawal, and an inability to plan and carry out future activities. The cognitive disturbances exhibited in schizophrenia include deficits in spatial reference and working memory as well as difficulties with focus and attention (Lewis et. al., 2007). Several models have been proposed …

Evaluating The Discriminant Validity Of The Metaphors Test, Daniel N. Erosa

McNair Poster Presentations

The Metaphors Test (Barchard, Hensley, Anderson, & Walker, 2013) is a new test of emotion per­ception in which test takers indicate the extent to which various emotions are conveyed by metaphors. In order for the Metaphors Test to be considered a valid test of emotion perception, it must have dis­criminant validity. The Five-Factor Model (McCrae & John, 1992), also known as the Big Five Model, is one of the most well-known frameworks for personality. Based upon theory and previous research, the Metaphors Test should have low correlations with the Big Five. Conscientiousness had a moder­ate correlation with the Metaphors Test. …

The Effect Of Spiritualism On The Cognitive Functions On Learning And Memory, Carla Antonieta Farcello

McNair Poster Presentations

Last summer I conducted a pilot study which researched whether better working memory would be documented among an experimental group (individuals who report being spiritual) as compared to the control group (individuals who report being non-spiritual).Total scores showed a significantly higher sense of spiritualism among the spiritual participants vs. the non spiritual participants (p < .001) along with a significant improvement in working memory for spiritual participants vs. non spiritual participants (p = .027). The results of this study documented significantly better performance on a task measuring emotional learning and memory among individuals who reported being spiritual as opposed to individuals who reported being non-spiritual. These findings build on prior studies suggesting the effect of positive emotions on broadening cognitive processes (Strauss & Allen, 2003).

My current study is building on what my prior findings have suggested and studies the effect of spiritualism on the cognitive functions of learning and memory. In addition to the Daily Spiritual Experiences Scale (DSES) used in the pilot study, I am including the Spirituality Index …

Evaluating The Convergent Validity Of The Measure Of Emotional Connotations, Daniel N. Erosa

McNair Poster Presentations

The Measure of Emotional Connotations (MEC; Barchard, Kirsch, Anderson, Grob, & Anderson, 2012) is a new test that has been developed to measure the ability to perceive the emotional connotations of written language. To examine its convergent validity, the MEC will be correlated with the two emotion perception tasks on the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT; Mayer, Salovey, Caruso, & Sitarenious, 2003). These MSCEIT tasks are valid tests of emotion perception; thus, strong correlations would provide support for the MEC as a valid test of emotion perception.

This study will review the current literature on the psychological and emotional implications associated with human sex trafficking, and analyze the components of narrative therapy and its previous application in treating domestic abuse trauma. This paper will explore the viability of narrative therapy as a method to treat the complicated traumas and stress developed as a victim of sexual trafficking. The ultimate goal of this literature analysis is to propose a study that utilizes narrative therapy as an approach that …

Post-Traumatic Stress Disorder: A Look Into The Cause, Gender Differences, And Treatment, Barbara Wallen

McNair Poster Presentations

Posttraumatic stress disorder, better known as PTSD came to light during the Vietnam Era. Throughout history, this stress disorder has been called various things in the 150 years since it was first recognized. However, each new word had several characteristics in common, such as re-experiencing, numbing and physiological arousal.

The process of Darwinian “natural selection” corroborated the evolution of people with highly developed stress responses. Those pre-historic people with the most useful “fight or flight” reflexes became our ancestors. An example of this is that during the 19^th Century, PTSD was called “Railway Spine” and was associated with what …

McNair Poster Presentations

The prevalence of Female Genital Mutilation and the difficulty in preventing its practice call for a fresh way of resolving the problem. As the availability of medical professionals equipped with the ability to correct clitoral mutilation grows, there is also an increasing need for professionals that can help the victims after the reconstructive surgery. Post-operative therapy for victims that have opted to receive reconstructive surgery is necessary in order to fully recover. Furthermore, more research in this area is needed to support the findings of this review and will fill the physical and emotional gap exhibited in prior studies related …

Influence Of Rap And Hip-Hop Lyrics On Male Body Image And Attitudes Toward Wwomen, Lorena Munoz

McNair Poster Presentations

Rap and hip-hop music are a widely popular and accessible genre of media. Its popularity and controversial lyrics raise questions as to the effects it may have on its audience. This study proposes to investigate the influence of rap and hip-hop music will be correlated with higher mean levels of thin-ideal appearance internalization (INT-GEN), negative attitudes towards women, and cultural expectations of masculinity compared to published normative data. Participants will complete online measures addressing questions about their body image (e.g. drive for muscularity) and attitudes toward women (e.g. objectification and misogyny). Future research should compare the influence of rap and …
