The Endowment Effect And Temporal Discounting Of Drug And Non-Drug Commodities, Sean D. Regnier, Mark J. Rzeszutek, Justin C. Strickland, Thomas Shellenberg, William W. Stoops

Behavioral Science Faculty Publications

Objectives: Despite a rich history of behavioral economic research on substance use there remains a need for further exploration of behavioral mechanisms that may underlie the etiology or persistence of substance use disorder. The purpose of this study was to measure the association between delay discounting and the endowment effect in people who smoke cigarettes, use cocaine, and controls, using online crowdsourcing. Methods: Participants were categorized to a cocaine group (n = 36), cigarette group (n = 48), or control group (n = 47) based on recent reported drug use. Based on group, participants completed up to three delay discounting …

The Moderating Effect Of Physical Activity On The Relationship Between Bullying And Mental Health Among Sexual And Gender Minority Youth, Sally J. Kirklewski, Ryan J. Watson, Carolyn Lauckner

Behavioral Science Faculty Publications

Background: Sexual and gender minority youth frequently experience bullying, which often contributes to higher depressive symptoms and lower self-esteem. Given that physical activity (PA) can mitigate depressive symptoms and improve self-esteem, we examined the moderating effect of PA on the relationship between bullying and mental health among sexual and gender minority youth.

Methods: Data from the Lesbian, Gay, Bisexual, Transgender, and Queer National Teen Survey (n = 9890) were analyzed. Hierarchical regression analyses examined the influence of history and frequency of being bullied, PA, and the interaction of these variables on depressive symptoms and self-esteem. Simple slopes analyses were used …

Effects Of Combined Ethanol And Nicotine Administration On Delay Discounting In Male And Female Sprague-Dawley Rats, Rebecca Lillian Chalme

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ethanol (EtOH) and nicotine (NIC) are among the most commonly used and co-used drugs in the world. Co-use occurs in people who use one or both drugs chronically, but also in people who only consume one or both drugs acutely, often in a “bingeing and chipping” pattern. Given that each drug on its own has previously been shown to affect impulsive choice in delay-discounting procedures, with some indication that drug effects could vary by sex, the purpose of the present experiments was to investigate effects of combined EtOH and NIC at a range of dose combinations on delay discounting in …

Effects Of Social Isolation And Adolescent Ethanol Exposure On Adult Drinking And Nicotine Co-Use, Jakob Shaykin

Theses and Dissertations--Psychology

Alcohol use often begins in adolescence and can lead to increased susceptibility to AUD in adulthood. Stress in the form of social isolation during adolescence can also prompt substance use disorders later in adulthood. This thesis determined if exposure to ethanol (EtOH) during adolescence and social isolation alters the trajectory of alcohol and nicotine intake during adulthood. In Experiment 1, adolescent male and female Sprague-Dawley rats were administered intermittent injections of EtOH (2g/kg 20% EtOH, IP) or saline (PND 28-41). EtOH consumption was measured in adulthood (PND 49-55) using a 2-bottle choice procedure where one bottle contained a 0.2% saccharin/15% …

Prenatal Ethanol Exposure Impairs Performance On Spatial And Tactile Sequential Discrimination Task In Juvenile Rats, Caleb S. Bailey

Theses and Dissertations--Psychology

Fetal alcohol spectrum disorders (FASDs) are a set of cognitive and behavioral abnormalities that arise in ~5% of children who have been prenatally-exposed to alcohol. Prenatal alcohol exposure (PAE) can cause impairments in learning acquisition, working memory, response inhibition, and attentional-set shifting that result in exaggerated deficits in executive function and impairments in goal-seeking behavior. There are standard procedures used in rodent research to address some components of these deficits, but few procedures are sensitive enough to comprehensively assess such deficits. To address this issue in FASDs research techniques, we developed a procedure that requires prolonged executive function in a …

Psychopathy And Insight Within An Incarcerated Population, Courtney Steinorth

Graduate Theses/Dissertations

The clinical construct of psychopathy has been researched extensively relative to incarceration. Cognitive insight has shown to be related to prognosis and treatment outcomes with severe psychopathologies. There has been, however, limited research on both psychopathy and cognitive insight in relation to incarceration. The purpose of the present study was to examine the moderation of cognitive insight levels on rates of incarceration (the number of times someone has been incarcerated in a government detention facility) based on their level of self-reported psychopathic traits. A brief demographic questionnaire, the Beck Cognitive Insight Scale, and the Levenson Self-Report Psychopathy Scale were administered …

Effects Of Ethanol And Nicotine Co-Administration On Risky Choice In Rats, Erin E. Wylie

Graduate Theses, Dissertations, and Problem Reports (ETD)

Individuals often engage in the comorbid use of alcohol (ethanol) and nicotine, leading to further-escalated health consequences than the use of either drug in isolation. Given the poor health outcomes resulting from the combined administration of ethanol and nicotine, some of which may be due to increased risky choice, more basic research is needed to better characterize drug/dose interactions on risky choice. Probability-discounting procedures involve a series of discrete choices between a smaller, certain reinforcer (i.e., a safer choice) and a larger, increasingly uncertain reinforcer (i.e., a riskier choice). Probability-discounting procedures allow for the assessment of …

Filipino Physical Therapists’ Practice And Perspectives On Non-Treatment Physical Activity For Older Adults, Frances Rom M. Lunar, Attilah Mae B. Alog, Alexa Ds Tanchuling, Kristen Mari Andal, Beatrice Camille Chan, Daniel C. Chua, Claire Beatrice Martinez, Ma. Anna Carmina D. Orlino, Jem Bettina G. Tan, Koji A. Katakura Jr., Marvin Louie S. Ignacio

Philippine Journal of Physical Therapy

Introduction:

Studies have already investigated the practice of physical therapists (PTs) in promoting non-treatment physical activity (NTPA). However, these were done in the context of mostly western settings or were not specific to older adult practice. It is still unclear if a similar level of practice and perspectives on NTPA promotion exists in a setting where physical therapy is more associated with rehabilitation than health promotion, such as in the Philippines. Therefore, this study aimed to describe Filipino PTs' knowledge of WHO physical activity (PA) guidelines and their use of behavioral change techniques (BCTs) and theories when promoting PA in …

Assessing The Mental Health Of Women At The Intersection Of Intimate Partner Violence And Animal Cruelty: Personal And Population Level Risk Factors For Co-Victimization, Alaina M. Beauchamp

Dissertations and Theses (Open Access)

One predictor of intimate partner violence (IPV) occurring in the home is pet abuse. The high prevalence of pet cruelty among IPV relationship can create a significant barrier to seeking help due to the inability to bring the pet or concern for the pet’s wellbeing. This human-animal bond is a more common source of emotional support among victims with experiences of pet abuse, as opposed to women whose pets had not been abused. This study 1) explored the relationship between victims of IPV and their pets, the dynamics and characteristics of situations of co-victimization (i.e., abuse of both a human …

Mental Health Benefits Of Physical Activity In Older Adults, Adrian Kurt Zitzmann

Master of Science in Nursing Family Nurse Practitioner

Physical activity is the fountain of youth, strengthening both the physical body as well as the mind, leading to better emotional stability and a general sense of well-being. The population over age 65 is nearing retirement age and are transitioning from a high paced work and family life to a slower and less active “empty nest” lifestyle. Among adults over age 65, will implementing an exercise program for 30 minutes per day increase mental well-being? The benefits of physical activity will be supported by gathering a group of older adults ages 65 and up from a local retirement community to …

Testing Wickelgren's Model Of Interference And Decay, Gabriel Hull, Isabella Lacy

Undergraduate Research Symposium Posters

Two explanations have been proposed to explain forgetting: decay (forgetting occurs as a function of time) and interference (the mental activity can impinge on the consolidation of a recently acquired memory). Wickelgren (1974) proposed a model of forgetting which suggests that forgetting is a function of both decay and interference, best expressed as a power-exponential function. The present research will be the first to directly examine whether Wickelgren’s model accurately predicts the observed effects of these two components on forgetting. This research will further the study of human memory by improving current models, and helping to resolve the debate surrounding …

Self-Blame Associated With Sexual Maltreatment, Jessica Castillo, Mallory Constantine

Undergraduate Research Symposium Posters

Sexually maltreated youth are at increased risk for developing thoughts of self-blame associated with their traumatic experiences (Melville et al., 2014). Self-blame increases risk of maladaptive emotion regulation strategies and self-harming behaviors (Gorgi et al., 2019). Self-blame can cause negative side effects in development and adulthood, changing the trajectory of the child who was affected by sexual assault (Ullman et al., 2014). Recent studies suggest we must continue to investigate the role in shame in producing meaning making progress, and how it affects other emotions, cognitive learning, and emotion regulating strategies (McElvaney et al., 2022). In order to continue to …

You're So Harsh On Me: Meanness In Psychopathy And Perceived Family Criticism, Jordan E. Hayes, Kayla Mcginty

Undergraduate Research Symposium Posters

Overall, the lack of research on percieved criticism, especially within populations that display meanness, show a need for research because just like mood, percieved criticism may change throughout the day. Understanding the relationship between psychopathic meanness and momentary patterns of percieved criticism among family members could provide helpful insight into social interactions and elucidating patterns of family dysfunction involved in the most antagonistic features of psychopathy.

Understanding The Contributions Of Hormonal Contraceptives And Cortisol Levels To Fear Learning In Women, Sahil Bardai

Symposium of Student Scholars

Women are twice as likely to be diagnosed with an anxiety disorder than men. Eighty-five percent of women in the US will use hormonal contraceptives at some point in their lifetime. Women who use hormonal contraceptives show heightened startle reactivity to a threatening stimulus. Previous results from our lab showed a significant increase in fear-potentiated startle (FPS) in women who were on hormonal contraceptives compared to women who were naturally cycling. These results stayed consistent throughout three acquisition trials. Others have shown that the use of OCPs (oral contraceptive pills) is related to the dysregulation of the HPA-axis and elevated …

Blind Spot: Implicit Bias In Health Care And Its Awareness Among Nursing Students At The University Of Southern Mississippi, Debora Skaliks

Doctoral Projects

While prejudice and bias are eminent topics in our society, implicit bias or unconscious bias is not as easily detected. Even though implicit bias may be a familiar concept to many, numerous healthcare workers frequently do not recognize the extent of harm such biases can impose on patients' health and outcomes. The Blind Spot DNP project exposed in this research paper explores the relentless question of the correlation between implicit bias awareness, implicit bias education, and its impact on health care. This Doctor of Nursing Project (DNP) project aimed to analyze whether implicit bias education and testing could increase unconscious …

The Impact Of Video-Taped Social Modeling On Alcohol Outcome Expectancies Of Young Adults And The Role Of Social Anxiety, Kyle Kevin Jackson

Graduate Theses and Dissertations

Alcohol outcome expectancies (AOEs) represent people’s ideas about the effects of alcohol (Fromme, 1993). Positive AOEs particularly have been identified as a potential risk factor for hazardous drinking (e.g., Brown et al., 1985). The exact mechanisms that modify AOEs are not fully understood. Further, people higher in social anxiety may be especially receptive to social modeling due to attentional bias shift towards others in social contexts (Rapee & Heimberg, 1997). The current study examined how social anxiety and social modeling associate with AOEs. It was hypothesized that 1) those in the social modeling treatment condition would have higher social anxiety-adjacent …

Corporations spend billions of dollars annually on hiring and training salespeople; yet, salespeople often quit or miss their quota targets. Considering this industry-wide business problem, the purpose of this dissertation study was to determine how sales competencies influence customer satisfaction and account profitability while taking into consideration the duration of …

Customer Willingness To Pay For All-Inclusive Resorts: A Choice-Based Conjoint Analysis, Liheng Zhang

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation examined customers’ willingness to pay for all-inclusive resorts using choice theory, the theory of bundling, and prospect theory. This dissertation also contributed to the current research by determining (a) the attributes that affect customers’ willingness to pay for an all-inclusive resort and (b) whether a reference price will affect customers’ willingness to pay. We also take into account the effect of the COVID-19 pandemic on customers and whether the pandemic will influence customers’ purchase behavior at this particular time. The choice-based conjoint analysis results showed that all eleven attributes—price, hotel star rating, type of room, location, food options, …

Individual Differences In Lpp Amplitude And Theta Power Predict Cue-Induced Eating During A Cued Food Delivery Task, Kyla Gibney

Dissertations and Theses (Open Access)

Due to individual differences in the brain’s reward system, some individuals are more vulnerable than others to maladaptive, reward-seeking behaviors, such as substance use or compulsive eating. A body of research has demonstrated that individuals who attribute higher levels of incentive salience to reward-associated cues than to pleasant images (termed “C>P group” throughout) are more vulnerable to compulsive eating than those who attribute higher incentive salience to pleasant images than reward- associated cues (P>C group). Meanwhile, a separate body of research has demonstrated that cognitive control also regulates eating by enabling top-down attentional control. This dissertation aims to …

Hiv And Early Life Stress On Neuroimaging And Risky Behavior, Paola Garcia Egan

Dissertations

This study examined the interactive effects of early life stress (ELS) and HIV on brain morphometry, diffusion-basis-spectrum-imaging (DBSI), risky decision-making, and sex-risk behavior. 122 people with HIV (PWH) and 113 people without HIV (PWoH), free of major psychiatric illness and neurological confounds, were stratified into high (≥ 3 events) vs. low (< 3 events) ELS [PWoH/low ELS (n = 57), PWoH/high ELS (n =56), PWH/low ELS (n = 43), PWH/high ELS (n = 79)] and underwent structural magnetic resonance imaging, DBSI, neuropsychological, and risky-behavior assessment; all PWH were virologically controlled. Compared to PWoH, PWH had smaller orbitofrontal cortex (OFC), parietal lobes, insula, caudate and anterior cingulate. No ELS effects were detected in volumetric measures. Significant interactions were found between HIV serostatus and ELS on the OFC and on cellularity of the inferior fronto-occipital fasciculus after multiple comparisons adjustment. Specifically, PWH/high ELS exhibited significantly smaller OFC and PWoH/high ELS show significantly larger OFC than the other groups. PWoH/high ELS exhibited higher DBSI cellularity (neuroinflammation proxy) of the inferior-occipital-fasciculus compared to PWoH/high ELS. Regardless of HIV status, executive function moderated the relationship between the OFC and sex-risk behavior such that individuals within the sample who performed above average on a measure of executive function and had a larger OFC reported fewer sex partners in past six months than individuals with smaller volumes. No interaction was found between HIV serostatus and ELS on risky behavior measures. Clustering analyses defined ELS subgroups in PWH that were determined by demographic characteristics, duration of infection, recent CD4+ T-cell count, nadir CD4+ T-cell count and high/low ELS.Even in PWH that are virologically controlled, without major current psychiatric comorbidities, there is evidence of a synergistic impact of ELS and HIV on OFC volumes. Higher volumes in the OFC were detrimental when associated with lower executive function scores or advantageous when associated with higher executive function. Findings suggest that ELS is associated with different brain signatures among PWoH and virally suppressed PWH. However, ELS was not directly associated with risky behaviors, and subgroups in PWH were characterized by demographic variables, past substance use and HIV clinical variables.

Adaptation And Study Protocol Of The Evidence-Based Make Better Choices (Mbc2) Multiple Diet And Activity Change Intervention For A Rural Appalachian Population, Nancy E. Schoenberg, Deanna Sherman, Angela Fidler Pfammatter, Michelle K. Roberts, Ming-Yuan Chih, Sarah Cornelia Vos, Bonnie Spring

Behavioral Science Faculty Publications

Background: Rural Appalachian residents experience among the highest prevalence of chronic disease, premature mortality, and decreased life expectancy in the nation. Addressing these growing inequities while avoiding dupli‑ cating existing programming necessitates the development of appropriate adaptations of evidence-based lifestyle interventions. Yet few published articles explicate how to accomplish such contextual and cultural adaptation.

Methods: In this paper, we describe the process of adapting the Make Better Choices 2 (MBC2) mHealth diet and activity randomized trial and the revised protocol for intervention implementation in rural Appalachia. Deploying the NIH’s Cultural Framework on Health and Aaron’s Adaptation framework, the …

Workplace violence is a common challenge seen in the healthcare settings across the world. This problem is steadily increasing in all types of hospitals, including a level one trauma center located in an urban area. There has been a steady rise in the number of assaults and workplace violence reported from bedside staff at this hospital. The leadership of the organization formed a work group to help combat the workplace violence and staff assaults that were occurring. In this process, a behavior response team was created to help nursing staff with escalating behavior in patients, and to help de-escalate the …

Dental Fear, Anxiety, And Phobia; Causes, Diagnostic Criteria And The Medical And Social Impact, Nadya Avramova

Journal of Mind and Medical Sciences

Despite technological advances in modern medical science and practice, many people still associate dental treatment with unpleasant emotional sensations and pain. According to the current literature, dental fear and anxiety are psychological barriers that negatively affect frequency of patient attendance which results in avoidant behavior and poorer oral health-related quality of life.

This paper was therefore aimed at discussing basic theoretical aspects concerning diagnostic criteria, causes, and impacts of dental fear, anxiety, and phobia. Clarifying their differential diagnostic characteristics, clinical features and specific causes may play an important role in proper diagnosing, positive influencing, and management of this group of …

Early Life Exposure To Unpredictable Parental Sensory Signals Shapes Cognitive Development Across Three Species, Elyssia Poggi Davis, Kari Mccormack, Hina Arora, Desiree Sharpe, Annabel K. Short, Jocelyne Bachevalier, Laura M. Glynn, Curt A. Sandman, Hal S. Stern, Mar Sanchez, Tallie Z. Baram

Psychology Faculty Articles and Research

Exposure to early life adversity has long term consequences on cognitive function. Most research has focused on understanding components of early life adversities that contribute to later risk, including poverty, trauma, maltreatment, and neglect. Whereas these factors, in the aggregate, explain a significant proportion of emotional and cognitive problems, there are serious gaps in our ability to identify potential mechanisms by which early life adversities might promote vulnerability or resilience. Here we discuss early life exposure to unpredictable signals from the caretaker as an understudied type of adversity that is amenable to prevention and intervention. We employ a translational approach …

Media Multitasking And Sustained Attention: An Experimental Investigation, Ryan Nix

Student Theses and Dissertations

Research exploring the cognitive effects of media multitasking show a lack of convergent findings among studies that utilize the Media Multitasking Index (MMI) and behavioral measures of sustained attention. All these studies approached media multitasking as a linear construct with solely cumulative effects. To investigate the possibility that media multitasking may have immediate, direct effects on sustained attention, a laboratory media multitasking simulation was implemented alongside the MMI and the Sustained Attention to Response Task (SART). Eighty-one participants completed all measures; half experienced the media multitasking simulation. It was predicted that experimental participants would exhibit more post-simulation SART NOGO errors …

A Paraventricular Thalamo-Accumbal Circuit Necessary For Behavioral Inhibition Is Dysfunctional During Opioid Use And Dependence, Kelsey M. Vollmer

MUSC Theses and Dissertations

Suppression of dangerous or inappropriate reward-motivated behaviors is critical for survival, whereas therapeutic or recreational opioid use can unleash detrimental behaviors and opioid use disorder (OUD). Nevertheless, the neuronal systems that suppress maladaptive motivated behaviors remain unclear, and whether opioids disengage those systems is unknown. Here, we investigate the posterior paraventricular thalamus (pPVT) as a behavioral mediator due to its strong connectivity with brain structures important for reward processing, such as the nucleus accumbens (NAc). We and others have found pPVT-NAc neuronal activity is inhibited during reward seeking, but activated when such behaviors would be inappropriate, such as during stress …

Prevalence And Outcomes Of The Use Of Telemedicine For Psychiatry Patients In The Outpatient Setting, Amberly Ray, Madison Dew, Udema Millsaps, Adeolu Funso Oladunjoye, Anna Fuchs, Danielle Hovington, Alexa Primavera, Aakash Padodara, Maria Yee, Eduardo Espiridion

Transformative Medicine

OBJECTIVE: With the recent surge in telepsychiatry utilization, it is important to study the effectiveness of this virtual modality. METHODS: To determine if telemedicine visits were effective in keeping psychiatric patients stable, a retrospective study was performed in an outpatient behavioral health setting using the OQ®45.2/Y-OQ® 30.2 assessment tool, which assesses patient reported outcomes across areas of functioning. To qualify for this study, patients needed at least two OQ scores with one being prior to the onset of telepsychiatry care and one being after returning to in-person care. RESULTS: 51.1% of adults (n=176) improved or remained the same, whereas 48.8% …
