Sex Differences In Stress Reactivity, Brain Morphology, And Oxytocin In The Hypothalamus Of The Gray Short-Tailed Opossum (Monodelphis Domestica), Esperanza I. Zacarias, Daniela Rodriguez, Alexandra Chalons, Sasawan Heingraj, Nicole Altamirano, Joseph Rafac, John L. Vandeberg, Mario Gil

Research Colloquium

Understanding the effects of stress on behavior and cognition is important due to its impact on mental health and wellbeing (Schneiderman et al. 2005). Translational animal research can contribute to the development of new treatments that can improve therapeutic outcomes and our understanding of the neurobiology of stress. In the present study, we complement behavioral stress reactivity with immunohistochemical localization of oxytocin in the hypothalamus, a neuropeptide that regulates stress (Neumann & Slattery, 2016). Oxytocin has potential therapeutic use for mental health disorders (Neumann & Slattery, 2016), and the effects of oxytocin seem to be sexually dimorphic (Love, 2018). Using …

Behavioral Economic Demand: Investigation Of Sex Differences In Four Core Genotype Model Of Oral Oxycodone Self-Administration, Michelle Elsmore, David Jentsch, Joshua Peck, Anushree Karkhanis

Undergraduate Honors Theses

Opioid misuse has been identified to be related to problematic release of dopamine in the brain that is otherwise satiated by other alternative rewards. As mediated by patterns of positive and negative reinforcement, prolonged opioid use may transition into misuse and development of opioid use disorder. In human populations, men and women differ in their acquisition of drug use and escalation to drug misuse. Women quickly surpass their male counterparts in their transition from use to misuse in what is coined the telescoping effect. In this four core genotype model of oral oxycodone self administration, males were hypothesized to consume …

The Effects Of Screen Time On Children, Jacqueline Valdepenas

Nursing | Senior Theses

With the development of technology continuing to grow at a fast-paced pace in society, children are now becoming exposed to such technology at a younger age. The introduction of smartphones and tablets, which is defined as screen time in this paper, are being introduced to children as young as 6 months of age. Instead of children playing with toys recommended for their age, they use screen time for their play needs and entertainment. Some parents use screen time as a distraction and/or relief for their own needs when the child is upset or they’re unable to tend to the child. …

Buprenorphine Effects On Anxiety-Like Behavior In B6 Mice, Megan K. Thibert

Select or Award-Winning Individual Scholarship

Buprenorphine, a semi-synthetic opioid prescribed for the treatment of opioid use disorder (OUD), has been suggested as a potential pharmacological treatment for anxiety. Some preclinical and clinical studies provide support for the anxiolytic effects of buprenorphine, but research in this area is scarce, and findings to date have been mixed. The present study was designed to test the hypothesis that buprenorphine alters anxiety-like behavior in C57BL/IJ (B6) mice measured using the elevated zero maze (EZM). Adult, male mice (n=10) were given subcutaneous injections of saline (control) and three doses of buprenorphine (0.3, 1, and 10 mg/kg). One hour following injection, …

Educational Intervention Program For Young Voters: Improving Political Knowledge And Voting Behavior In The 2020 Simultaneous Local Elections, Muhammad Abdan Shadiqi, Gusti Ernawati, Rima Hariati, Khaerullah Fadhli Hasan Arasy, Noor I’Anah, Wita Al Istiqomah, Ulfiyah Nanda Firman, Neka Erlyani

Jurnal Politik

Young voters' low level of political knowledge, which impacts political participation, is still a phenomenon today. The influence of political knowledge on young voters' behavior is still being debated, and there is little empirical evidence, especially regarding political knowledge and voting behavior enhanced through specific educational programs. Therefore, an effective education program is needed to increase political knowledge and the desire of young voters to participate in general elections. This study aims to determine the effectiveness of educational programs in increasing political knowledge and shaping voting behavior among young voters in South Kalimantan Local Elections (Pilkada). We used a quasi-experimental …

Unresolved Issues Of Behavioral Analysis In Invertebrates, Charles I. Abramson, Paco Calvo

Animal Sentience

Crump et al. (2022) provide a framework for determining the presence of sentience in organisms. Their target article is interesting and thought-provoking, but it does not consider the many unresolved issues related to behavioral analysis – especially when it concerns invertebrates. We feel that no real progress can be made until such fundamental issues as the need for a consistent definition of conditioning phenomena, the lack of a generally accepted behavioral taxonomy, and the use of cognitive terms to explain invertebrate behavior are examined critically.

Development And Testing Of Remote Facilitation Of Prevent-Teach-Reinforce For Families To Address Challenging Behavior In Young Children (Ptr-F:R), Abby Hodges

Electronic Theses and Dissertations

As children advance through developmental stages, they often present behavioral difficulties such as tantrums, lack of cooperation, and aggression. For some children, behaviors are serious enough that they interfere with the child’s ability to engage in positive relationships, participate in necessary routines, and learn new skills, warranting behavioral intervention (Dunlap et al., 2017). Being responsive to the needs of the family and appreciation for the central role that they play is crucial to the success of behavioral interventions and the maintenance of positive outcomes (Bailey, 2013; Campbell, 1995), thus, their input should be at the center of all recommendations and …

Sugar Glider (Petaurus Breviceps) Behavior In Red Vs Blue Lighting, Elisa Hillman

Honors Thesis

Sugar gliders are an exotic pet that is increasing in popularity in households as well as in zoos. One challenge that caregivers have to manage is their nocturnal circadian rhythm. In order for people to view or interact with sugar gliders during their active time, many zoos will reverse their diurnal cycle with lights. The discovery of intrinsically photosensitive retinal ganglion cells (ipRGCs) which seems to have an increased sensitivity to blue light and how these cells affect the hypothalamic suprachiasmatic nucleus (SCN) and circadian rhythm has led to an increase in awareness on the health effects of being exposed …

America's Newest Boogeyman For Deviant Teen Behavior: Violent Video Games And The First Amendment, Joseph C. Alfe, Grant D. Talabay

Pace Intellectual Property, Sports & Entertainment Law Forum

Are violent video games harming America’s youth? Is it possible a series of interconnected circuit boards can influence children (or even adults) to become, themselves, violent? If so, how should our society-- and government-- respond?

To properly answer this last query, violent video games must be viewed through the lens of the First Amendment. Simply put: do games depicting grotesque acts of depravity so profound as to negatively influence the psyche warrant the full constitutional protections ordinarily guaranteed under the mantle of free speech and expression? Are these guarantees without limit? If not, how far may the government go in …

Alternatives: The Video Game. An Assessment Of Bias And Preferences In Uncertain Situations, Vincent Edwards

Electronic Theses and Dissertations

Going against working assumptions of what is "natural", animals have been observed to "gamble" when choosing between a high-risk choice with a high reward, and a consistent alternative with a low reward that feeds them more over time. The Energy Budget Rule (EBR) claims that animals have a foraging goal they must reach to survive, and each attempt to forage has a cost; under certain conditions, a high risk "gamble" is the best option for survival. The present study attempts to observe human choice behavior in a task that tests EBR and assesses shifts in behavior over time as an …

Behavioural Risks In Female Dogs With Minimal Lifetime Exposure To Gonadal Hormones, Melissa J. Starling, Anne Fawcett, Bethany Wilson, James Serpell, Paul Mcgreevy

Physiology Collection

Spaying of female dogs is a widespread practice, performed primarily for population control. While the consequences of early spaying for health are still being debated, the consequences for behaviour are believed to be negligible. The current study focused on the reported behaviour of 8981 female dogs spayed before 520 weeks (ten years) of life for reasons other than behavioural management, and calculated their percentage lifetime exposure to gonadal hormones (PLGH) as a proportion of their age at the time of being reported to the online Canine Behavioral Assessment and Research Questionnaire (C-BARQ). We found that 23 behaviours differed between entire …

Behavioral Impairment Following Gestational Exposure To Titanium Dioxide Nanomaterial Aerosols In Male And Female Rats, Matthew Leland Eckard

Graduate Theses, Dissertations, and Problem Reports

Engineered nanomaterials (ENMs) are beginning to be recognized as hazardous to human and animal health. Titanium dioxide (TiO2) is primarily used as a whitening agent in paints, plastics, and sunscreens. While relatively inert in its bulk form, nano-TiO2 (diameter) can produce prolonged inflammation and oxidative stress in target tissue. Recently, the potential for nano-TiO2 to cause neuroinflammation and damage has heightened concerns about its continued use. One important concern is that nano-TiO2, and other metal oxide ENMs, may affect fetal neurodevelopment. Accordingly, it is imperative to screen ENMs, like TiO2, for possible neurotoxicity following developmental exposures. The current set of …

Bubble Stream Production By Belugas (Delphinapterus Leucas), Megan Slack

Theses

Bubble stream production in belugas has been poorly characterized and its function is not well understood. I examined behavioral states when producing bubble streams (“bubbling”), and when bubbling calls, to determine whether bubbling was significantly associated with a particular call category or behavioral state. Using 19 hours of video and audio recordings collected over a two-day period, I quantified bubble streams of a 4-month old calf and an unrelated adult female housed together. Based on the overall activity budgets and pool of vocalizations for both animals, I calculated the expected counts of bubble streams with and without vocalizations, assuming that …

The Effects Of Gateway Width On Driver Yielding To Pedestrians: A Systematic And Parametric Analysis, Jonathan M. Hochmuth

Masters Theses

The gateway in-street sign treatment has been demonstrated to be a cost-effective method for increasing driver yielding behavior at crosswalks. In the present study, wide and narrow gateway widths were compared at two sites to determine if there was a differential effect on driver yielding behavior. Then, the relationship between width and yielding was refined with a parametric analysis at one of these sites. Gateway width was varied in two-foot intervals from 12ft to 18ft. The results indicated an inverse relationship between gateway width and driver yielding behavior. There are likely two variables related to this effect. First, because drivers …

Neurochemistry, Physiology, And Behavior In A Model Of Gulf War Illness, Victoria A. Macht

Theses and Dissertations

Upon returning from the first Gulf War, soldiers cited a plethora of unexplained physical and cognitive deficits which have since been termed Gulf War Illness (GWI). Presentation of GWI is positively correlated with pyridostigmine bromide (PB) use, which was prophylactically administered to soldiers in response to threats of chemical warfare. To test the overarching hypothesis that PB interacted with stress of deployment to alter neural, endocrine, and immune systems, the following studies used a 2×2 rodent model with 14 days of drug treatment (vehicle; PB) and 10 days of repeated restraint stress (stressed) or non-stressed-control conditions. Results indicate that PB …

Alcohol-Induced Impairment Of Simulated Driving Performance And Behavioral Impulsivity In Dui Offenders, Nicholas A. Van Dyke

Theses and Dissertations--Psychology

Licensed drivers arrested for driving under the influence (DUI) of alcohol have increased rates of vehicle crashes, moving violations, traffic tickets, and contribute to an estimated 120 million occurrences of impaired driving per year (Evans, 2004; Jewett et al., 2015). Survey research on DUI offenders indicates traits of impulsivity (e.g., sensation seeking). Together, these pieces of evidence suggest that DUI offenders display patterns of impulsive action and risk-taking while driving. However, to-date DUI offenders are rarely studied in a laboratory setting, and not much is known about how they respond to a dose of alcohol. The present study examined the …

An Evaluation Of Traffic Control Devices And Driver Distraction On Driver Behavior At Railway-Highway Grade Crossings, Radhameris A. Gomez Gabriel

Doctoral Dissertations

At-grade crossings (grade crossings) are those crossings in which any part of a roadway intersects with railroad tracks. Safety at these railroad-highway grade crossings is a major concern, with traffic control warning devices serving as the main mechanisms for improving safety. There are three factors that influence a driver’s behavior at a given crossing. First, traffic control devices, including warning devices at the railroad-highway grade crossings, provide the driver with information whose impact will depend in part on the likelihood that the driver knows whether to glance in the direction of the device based on prior experience, and in part …

Food Porn & A Snack: Investigating The Effect Of Mindset On A Taste Test, Kingshuk Mazumdar

Honors Theses

The hot/cool system framework represents a dichotomy within cognitive functioning that moderates the exertion of self-control. While the cool system can be described as a cognitive and emotionally stable construct that serves as the center for self-regulation and control, the hot system forms the basis for emotionality, passion, and impulsivity. Research evidence suggests that attentional priming towards hot or cool cognitions may have a direct and measureable influence on behavior in a variety of social psychological domains. The present study investigated the effect of attentional priming towards hot or cool systems on snack food consumption in 142 college students. Participants …

Towards A Better Understanding Of Zebrafish Sleep Behavior, Kanza Musarrat Khan

Master's Theses

Sleep serves many vital functions in humans, ranging from energy restoration to memory consolidation and information integration. Sleep deprivation is linked to worsened physiological states and psychological conditions. Zebrafish are an emerging model in neurobehavioral research and have recently demonstrated great utility in the study of sleep. This teleost species possesses several of the same neurotransmitter and neuropeptide systems that are involved in the regulation of sleep and waking rhythms in higher order mammals. Previous study of these animals has revealed a differential gene and proteomic expression following sleep deprivation through changes in environmental stimuli. The present study sought to …

Culture Of Gentleness: A Behavioral Approach, Stevie Parcell

Honors Theses

The purpose of this paper is to explain the fundamentals of an ideological framework for caregivers providing services to people with disabilities called a Culture of Gentleness. The material is traditionally taught within the two-day Working with People training, and the efforts to spread this theory is headed by the Center for Positive Living Supports located in Clinton Township, Michigan. The material is then analyzed through a behavior analytic perspective. Each segment of the initial training will be discussed through both a Culture of Gentleness and behavioral perspective, rooted in Applied Behavior Analysis. Although established in the practice of Positive …

A Survey Of Rewards For Teens: Extension, Replication, And 25-Year Follow-Up, Hunter King

All Graduate Theses, Dissertations, and Other Capstone Projects

Changes in our immediate environment--as well as our virtual--have great potential to decrease the reinforcing effects of stimuli once identified as potent and reliable in past generations. Extant reinforcement surveys and item preferences assessments alike have shown to be a reliable mode of ascertaining potent reinforcers for various populations; however, many are outdated and may comprise of items or rewards that contemporary populations may not value. Considering the substantial environmental changes that have occurred over recent decades, in tandem with the availability of outdated reward surveys, efforts should be directed towards obtaining empirical evidence demonstrating that contemporary adolescents hold different …

Comparing The Effects Of Menthol Status On The Behavioral Pharmacology Of Smoking Reduced Nicotine Content Cigarettes, Danielle Davis

Graduate College Dissertations and Theses

Introduction: An active area of tobacco regulatory science research focuses on examining the effects of varying the nicotine content of cigarettes as part of a potential national policy to lower their nicotine content levels to reduce addiction potential. The present study examines differences in the behavioral effects of reduced nicotine content cigarettes related to their menthol status. Menthol is the only cigarette flavoring that is still legally permissible according to Food and Drug administration regulations.

Methods: Participants were 26 current adult smokers from three populations especially vulnerable to tobacco use and addiction (economically disadvantaged women, opioid-dependent individuals, individuals with affective …

Habitat Use By Bottlenose Dolphins, Tursiops Truncatus, In Roanoke Sound, North Carolina, Shauna Marisa Mcbride

Dissertations

Information on the habitat use of a species is important to develop conservation efforts and management strategies for that species. Roanoke Sound, North Carolina is primarily a seasonal habitat for bottlenose dolphins, Tursiops truncatus, from late spring to early fall, but little information is known about how dolphins use this area. Transect survey data and opportunistic survey data collected by the Outer Banks Center for Dolphin Research from 2009 to 2015 were used to analyze dolphin habitat use. The objectives of this project were to: 1) identify areas that were important to dolphins, 2) determine which behaviors were observed …

The Effect Of Auditory Stimulation On Sleep Disruption In West Indian Manatee (Trichechus Manatus Latirostris), Natalija Lace

Dissertations

Florida manatees inhabit waterways where motorized boats are common. Although manatee mortalities resulting from boat strikes are well documented, the effect of boat noise on some manatee behaviors, including rest, has not been investigated. This study focuses on rest behavior and used a playback experiment with four manatees at the Lowry Park Zoo in Florida. We tested their responses to playback stimuli of either boat noise, silence, or manatee calls. A playback trial was initiated when the focal animal showed behavioral characteristics of rest.

Results showed that rest was interrupted in response to the playback of boat noise for each …

Examining The Effectiveness Of A Training Video On The Lmplementation And Lnterpretation Of A Functional Analysis, Alissa Anne Conway

Masters Theses

Functional behavior assessment (FBA), and more specifically functional analysis (FA), refer to structured assessment processes designed to identify the controlling variables for challenging behaviors across children, adolescents, and adults. The results from a functional analysis are used to match therapy techniques to unique causal variables for challenging behaviors and also to select more adaptive replacement behaviors that produce similar functions as the challenging behaviors. As functional analysis techniques, in all variations, have become more commonplace in applied behavior analysis (ABA), attention has turned to how to train practitioners to implement FAs, interpret the results, and use the FAs to inform …

The Neurobehavioral Consequences Of Gestational And Chronic Atrazine Exposure In Male And Female Sprague Dawley Rats, Jennifer L. Walters

Dissertations

The adverse health risks of exposure to the herbicide, atrazine, in humans are not fully understood. Although numerous studies have demonstrated atrazine to be an endocrine disrupter, the neurobehavioral consequences of atrazine exposure have not been thoroughly examined. The aim of this study was to investigate the effects of environmentally-relevant levels

of gestational followed by continued chronic atrazine exposure on motor function, learning and memory, anxiety, and striatal dopamine content in rodents. Pregnant Sprague Dawley rats were treated by gavage with 100 µg/kg atrazine (ATZ low), 10 me/kg atrazine (ATZ high), or vehicle on

gestational day l through postnatal day …

Does Nicotine Alter What Is Learned About Non-Drug Incentives?, Tarra L. Baker

Undergraduate Honors Theses

Nicotine is one of the most addictive drugs known to man, yet it has limited reinforcing effects in humans and non-human animals when it is not self-administered in tobacco products. One hypothesis for these paradoxical effects of nicotine is that the effects of the drug in the brain alter acquisition of incentive learning. The hypothesis for this study is that nicotine will increase the value of cues paired with a reward. To test this hypothesis, 26 Sprague Dawley Male rats were randomly assigned to one of three groups Pre-NIC (the critical experimental group), Post-NIC and SAL. Each group received a …

Effects Of Proton Radiation And Pomegranates On Hippocampus And Behavior, Melissa S. Dulcich

Loma Linda University Electronic Theses, Dissertations & Projects

Exposure to ionizing radiation may have deleterious effects on physical and mental health, with an increased risk of proton radiation for astronauts traveling outside Earth's atmosphere into lower earth orbit. In animal models, radiation has been shown to suppress neurogenesis in the subgranular zone of the hippocampus, a key area for learning and memory. Furthermore, some evidence suggests that compounds found in fruits and vegetables (e.g. polyphenols) may offer some protection against the cellular effects of radiation. Few studies have looked at the effects of proton radiation on the central nervous system, even though proton radiation is the most prevalent …

A Punishment-Free, Toilet-Training Protocol For Children With Developmental Disabilities, Chelsea Lynn Pearsall

All Master's Theses

The present investigation adapted a behaviorally-based toilet-training protocol for use with two male children with developmental disabilities. Positive practice and verbal reprimands were eliminated, and reinforcement, scheduled sits, and a urine alarm were utilized. Data were collected on the number of intoilet urinations, urinary accidents, and self-initiations. Results show that both participants exhibited significant improvement in their toileting skills and met the final success criteria rapidly. These results were maintained through follow-up. Implications for the elimination of punishment procedures in future toilet training protocols are discussed.
