Playing With Fire Or Arson? Identifying Predictors Of Juvenile Firesetting Behavior, Mary Ellen Britt

UNLV Theses, Dissertations, Professional Papers, and Capstones

Firesetting is a complex behavior that spans a wide range of developmental stages in childhood and adolescence and involves varying motivations and intents. A better understanding of this destructive behavior is critical to developing strategies to control its devastating effects. The purpose of this research project was to identify potential predictors of juvenile firesetting behavior by studying youth who were enrolled in a regional firesetting intervention program. Data collected from firesetting assessment instruments completed by parents or guardians of program participants were examined. In the analyses, special emphasis was placed on evaluating associations between juvenile firesetting behavior and the socioeconomic …

The Effect Of Early Environmental Manipulation On Locomotor Sensitivity And Methamphetamine Condition Place Preference Reward, Emily Hensleigh

UNLV Theses, Dissertations, Professional Papers, and Capstones

Early life stress has drastic effects on neurological development, affecting health and well-being later in life. Instances of child abuse and neglect are associated with higher rates of depression, risk taking behavior, and an increased risk of drug abuse later in life (Chapman,D.P. 2004; Dube,S.R. 2003). This study used repeated neonatal separation of rat pups as a model of early life stress. Rat pups were either handled and weighed as controls or separated for 180 minutes per day during postnatal days 2-8. In adulthood, rats were tested for methamphetamine conditioned place preference reward and methamphetamine induced locomotor activity. Tissue samples …

Personality, Presence, And The Virtual Self: A Five-Factor Model Approach To Behavioral Analysis Within A Virtual Environment, Michael Patrick Mccreery

UNLV Theses, Dissertations, Professional Papers, and Capstones

For several decades, researchers have explored the existence of the virtual self, or digital embodiment of self found within an avatar. It was surmised that this new component of one’s overall identity not only existed in conjunction with the public and private persona, but was replete with the necessary physical and psychological characteristics that facilitate a broad range of cognitive, cultural, and socio-emotional outcomes found within a virtual environment (e.g., Second Life, World of Warcraft). However, little is known with regard to whether these characteristics do indeed impact behavioral outcomes. For this reason, this study employed an observational assessment method …

Common Core Thesis And A Qualitative And Quantitative Analysis Of Mysticism In Chinese Buddhist Monks And Nuns, Zhuo Chen

Masters Theses and Doctoral Dissertations

This study explored the phenomenological structure of mystical experience among 139 Chinese Pure Land and Chan Buddhist monks and nuns. Semi-structured interviews, thematic coding, and statistical analyses identified Hood’s Mysticism Scale as a valid tool for studying mysticism across religions and cultures. Stace’s common facets of mysticism as measured by Hood’s scale successfully described Buddhist experience as modified by Buddhist doctrines. Confirmatory factor analysis demonstrated that these facets could be formed into Stace’s three-factor structure. A mystical introvertive unity hypothesized to be separate from an extrovertive unity appeared instead to converge in the Chinese Buddhist context. These results lent strong …

The Structure Of Equine Personality, Rachel Etta Kristiansen

Dissertations

The current study was designed to investigate the structure of equine personality. Two personality questionnaires were replicated from previous studies and implemented simultaneously to test the theory that different questionnaires may extract different personality structures. Breed and sex differences were also hypothesized to be significantly different for some personality dimensions. A total of 827 horses were rated on a 90-item personality questionnaire. Participants were recruited online via email and completed the survey at their own convenience. An additional 121 respondents rated a horse that had already been rated; these results were used to calculate inter-rater reliability.

After data collection was …

Hand Preference For Coordinated Bimanual Actions In 777 Great Apes: Implications For The Evolution Of Handedness In Hominins, William D. Hopkins, Kimberley A. Phillips, A. Bania, S. E. Calcutt, M. Gardner, J. Russell, J. Schaeffer, E. V. Lonsdorf, S. R. Ross, S. J. Schapiro

Psychology Faculty Research

Whether or not nonhuman primates exhibit population-level handedness remains a topic of considerable scientific debate. Here, we examined handedness for coordinated bimanual actions in a sample of 777 great apes including chimpanzees, bonobos, gorillas, and orangutans. We found population-level right-handedness in chimpanzees, bonobos and gorillas, but left-handedness in orangutans. Directional biases in handedness were consistent across independent samples of apes within each genus. We suggest that, contrary to previous claims, population-level handedness is evident in great apes but differs among species as a result of ecological adaptations associated with posture and locomotion. We further suggest that historical views of nonhuman …

Ultrasound As An Aversive Stimulus For Use With Rats: A Novel Model Of Aversive Control, Brandon Norlund

Undergraduate Honors Capstone Projects

Negative reinforcers serve to maintain or increase behavior through the removal of an aversive stimulus. The primary method of studying negative reinforcement in non-humans has been through the use of electrical shock. While this method has proven to be reliable, many negative reinforcers that humans and non-humans encounter do not elicit tactile pain. Therefore, the purpose of this study was to explore a novel, non-human animal model of aversive control without the use of electrical shock as the negative reinforcer. A considerable amount of research has shown that various strains of rats find ultrasonic tones of certain frequencies and amplitudes …

Nondrug Reinforcement Loss And Relapse To Alcohol Seeking In Another Context, Adam D. Pyszczynski

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Extinguished alcohol-maintained responding has been shown to relapse in a
resurgence preparation when food-reinforced responding is subsequently extinguished within the same context. However, drug and nondrug reinforcers are often specific to different contexts. Accordingly, the present experiments sought to determine whether loss of an alternative source of nondrug reinforcement in one context could produce relapse to drug seeking in a separate context. In one experiment, rats made topographically different responses for food or alcohol in alternating components of a multiple schedule. Both reinforcers were delivered during baseline, alcohol was withheld during the second phase of the experiment, and finally both …

Preventative Behavioral Parent Training: A Preliminary Investigation Of Strategies For Preventing At-Risk Children From Developing Later Conduct Problems, Jessica L. Malmberg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Children exhibiting conduct problems comprise the largest source of referrals to children's mental health services in this county. Significant research has been conducted in an attempt to identify specific risk factors that result in increased vulnerability of a child developing conduct problems. Knowledge of these factors increases our ability to identify young children who are at greater risk for developing conduct problems. The treatment for conduct problems that possesses the greatest amount of empirical support is behavioral parent training. Yet behavioral parent training fails to address behaviors and risk factors that are present during a child's early development. Preventative behavioral …

What is a Human Person? An Exploration and Critique of Physicalist Perspectives

Emmanuel Cumplido

Faculty Sponsor: Donald Zeyl, Philosophy

Answers to the question “What is a human person?” that have garnered the allegiance of people throughout millennia fall under two broad categories: “physicalism” and “dualism”. One of the earliest renditions of physicalism was the philosophy of the ancient Greek atomists. In their view, all of reality could be explained through two principles: atoms and empty space. As a consequence, people were thought to be nothing but assemblages of atoms in space. Plato’s Phaedo presents one of the earliest philosophical endorsements …

Designing A School Garden Space That Emphasizes Children's Wants And Uses Permaculture Design Methods, Mikhaela Mullins

Department of Environmental Studies: Undergraduate Student Theses

A case study was organized at Saratoga Elementary school in Lincoln, Nebraska to obtain data on what children desire in a garden space. To collect this data a school garden space was constructed and an after school garden club was implemented. Students who participated in the after school garden club partook in the study by drawing their ideal garden. Elements that the subjects drew were identified and categorized into ‘highly desired’ and ‘somewhat desired’.

These elements were then incorporated into a proposed garden design plan for Saratoga. The proposal plan uses Permaculture design methods to emphasize sustainability.

Reactivation Of Negated Concepts Over Time, Kevin Autry

Graduate Theses and Dissertations

Research on the mental representation of negated concepts in written texts has yet to reach a consensus about the effects of negation. MacDonald and Just (1989) reported that after reading a sentence with a negation, negated words took longer to recognize than non-negated words, which suggests that the negated concepts became less active. However, Hasson and Glucksberg (2006) found that after reading negative metaphors (e.g., This surgeon isn't a butcher), lexical decisions about words consistent with the affirmative sense of the negated word (e.g., clumsy) took less time than for control words. To reconcile these (and other) incompatible findings, two …

An Exploratory Investigation On The Effects Of An Electronic Recording System For Repeated Reading, Seajae Calvin Hartness

Dissertations

Repeated Reading is a common reading intervention that has been used to help students read fluently since 1979. There are many variations of Repeated Reading that have been investigated and found to be effective. However, there is a relative research deficit on the effectiveness of software programs for administering Repeated Reading. This exploratory research project examined the effectiveness of Repeated Reading with an electronic recording system. The performance of the electronic Repeated Reading group was compared to the performance of participants who received traditionally administered Early Intervention Program services. The results suggest that electronically scored Repeated Reading is as effective …

Discriminative Stimulus Properties Of 3-Substituent Rimonabant Analogs, D. Matthew Walentiny

Theses and Dissertations

Cannabinoid agonists (e.g., THC) dose-dependently decrease locomotor activity and body temperature and produce antinociception and catalepsy. Drugs that produce this tetrad of effects within a limited dose range are likely to function as CB1 receptor agonists. A structure activity relationship study from our laboratory investigating analogs of the CB1 antagonist rimonabant revealed that certain alterations in the 3-substituent of rimonabant’s pyrazole core conferred agonist-like properties in the tetrad. Interestingly, these effects were present in CB1 -/- mice, and were not reversed by rimonabant in wild-type mice. The present study evaluated two novel 3-substituent rimonabant analogs, O-6629 and O-6658 in the …

Debrazza’S Monkeys (Cercopithecus Neglectus) In A Mixed-Taxa Zoo Exhibit: Effects On The Behavior Of A Breeding Group Of Debrazza’S Monkeys After The Birth Of An Infant, Rachel Diamond

Psychology Honors Projects

Historically, zoos rarely feature mixed taxa exhibits including multiple primate species; the Minnesota Zoo opened such a unique four-species exhibit featuring Rock hyraxes, Red River hogs, Colobus monkeys, and DeBrazza’s monkeys in May, 2010. Because of potential problems associated with territoriality and aggression, primates in mixed-taxa exhibits are generally non-breeding. However, the DeBrazza’s monkeys at the MN Zoo are a breeding pair with a juvenile offspring. The intent of this study was to design an ethogram with the purpose of calculating the effects of a mixed taxa exhibit on the behavior of this breeding group, and to compare their behavior …

Cyberostracism And Social Monitoring: Social Anxiety's Effects On Reactions To Exclusion And Inclusion Online, Claire E. Karlen, Jennifer R. Daniels Ph. D.

Honors Projects

Previous research has shown that ostracism –the equivalence of exclusion in a social situation –improves social monitoring abilities – a natural practice by which individuals gather information through social cues about what is happening in their social worlds (Pickett, Gardner, & Knowles, 2004). Current knowledge on social anxiety, defined as a chronic fear of social situations that put one in the position of evaluation by others, describes hypersensitivity in those individuals in cases of social monitoring others (Barlow, 2002; Craske, 1999). The current study investigated how those two constructs interacted in a cyberostracism paradigm. After measuring their social anxiety levels, …

Neural Activity During Social Exclusion: An Exploratory Examination, Stephanie Khatcherian

Honors Projects

Social exclusion has been brought to the forefront of media attention in recent years due to the recent tragedies like campus shootings and cyberbullying on social networking websites. In order to gain a deeper understanding of social exclusion, this study examined the relation between social exclusion and event-related brain potential (ERP) activity. ERPs were collected while participants completed three blocks of the Cyberball paradigm during which they experienced situations of social inclusion, exclusion, and re-inclusion. This well-established paradigm mimics actual social behavior experienced in real-world situations. Results showed larger N2 and smaller P3 amplitudes during throws where participants were excluded …

Is Everybody Doing It? Sex In The College Freshman Female Population, Alexandra I. Zelin

Departmental Honors & Graduate Capstone Projects

Descriptive and injunctive norms have been shown to influence people’s perceptions of what actions are considered appropriate. Social norms research with sexual behaviors has shown that women perceived other women to be highly sexually active when, in reality, these norms were not accurate. We anticipated the same pattern of misperceptions and wanted to see if perceived number of partners and permissive attitudes of best friends and the typical freshman could predict women’s own number of partners controlling for their own attitudes. Participants included 156 heterosexual, freshman women from a liberal arts university. We found that women perceived their friends and …

Understanding Client Imagery In Art Therapy, Erica K.M. Curtis

Journal of Clinical Art Therapy

This study offers a preliminary investigation into the question: How do art therapists make meaning from viewing client-made art? Art therapy literature on making meaning from client art is reviewed. The Visual Thinking Strategies (VTS) model used in art education and museum education is also briefly discussed for its parallels to this study’s findings. An adapted form of grounded theory for data collection and analysis was used, leading to emergent themes that suggest that understanding client art requires more than analyzing content and aesthetic elements. More specifically, this inquiry offers the consideration that viewing client art is a dynamic practice …

Analysis Of Morris Water Maze Data With Bayesian Statistical Methods, Maxym V. Myroshnychenko, Anton Westveld, Jefferson Kinney

Festival of Communities: UG Symposium (Posters)

Neuroscientists commonly use a Morris Water Maze to assess learning in rodents. In his kind of a maze, the subjects learn to swim toward a platform hidden in opaque water as they orient themselves according to the cues on the walls. This protocol presents a challenge to statistical analysis, because an artificial cut-off must be set for those experimental subjects that do not reach the platform so as they do not drown from exhaustion. This fact leads to the data being right censored. In our experimental data, which compares learning in rodents that have chemically induced symptoms of schizophrenia to …

Pulsed Radiofrequency Neuromodulation Of Peripheral Nerve Injury, Alex Willett, Joseph Williams, Faculty Advisor

John Wesley Powell Student Research Conference

Pulsed-radiofrequency neuromodulation (PRF) is a pain management technique that involves placing a needle electrode near nerves and generating electrical current pulses in order to modulate the transduction of somatosensory information through those nerves. This technique evolved from a similar radiofrequency (RF) procedure in which constant current is distributed to a nerve or neural structure. RF interrupts nerve conduction and prevents somatosensory information from reaching the brain. In the case of continuous radiofrequency, however, the destructive lesion can cause further complications and unwanted side effects. According to research, PRF, unlike RF, is non-destructive yet still induces analgesia and consequently represents a …

Assortative Mating In Fallow Deer Reduces The Strength Of Sexual Selection, Mary E. Farrell, Elodie Briefer, Alan G. Mcelligott

Veterinary Science and Medicine Collection

Background: Assortative mating can help explain how genetic variation for male quality is maintained even in highly polygynous species. Here, we present a longitudinal study examining how female and male ages, as well as male social dominance, affect assortative mating in fallow deer (Dama dama) over 10 years. Assortative mating could help explain the substantial proportion of females that do not mate with prime-aged, high ranking males, despite very high mating skew. We investigated the temporal pattern of female and male matings, and the relationship between female age and the age and dominance of their mates.

Results: The peak of …

Development And Validation Of The Minnesota Borderline Personality Disorder Scale, Marina Bornovalova, Brian M Hicks, Christopher J. Patrick, William G Iacono, Matt Mcgue

Psychology Faculty Publications

Although large epidemiological data sets can inform research on the etiology and development of borderline personality disorder (BPD), they rarely include BPD measures. In some cases, however, proxy measures can be constructed using instruments already in these data sets. In this study, the authors developed and validated a self-report measure of BPD from the Multidimensional Personality Questionnaire (MPQ). Items for the new instrument—the Minnesota BPD scale (MBPD) —were identified and refined using three large samples: undergraduates, community adolescent twins, and urban substance users. The authors determined the construct validity of the MBPD scale by examining its association with (a) diagnosed …

Longitudinal Changes In The Corpus Callosum Following Pediatric Traumatic Brain Injury As Assessed By Volumetric Mri And Diffusion Tensor Imaging, Trevor Chuang Kuo Wu

Theses and Dissertations

Atrophy of the corpus callosum (CC) is a documented consequence of moderate-to-severe traumatic brain injury (TBI), which has been expressed as volume loss using quantitative magnetic resonance imaging (MRI). Other advanced imaging modalities such as diffusion tensor imaging (DTI) have also detected white matter microstructural alteration following TBI in the CC. The manner and degree to which macrostructural changes such as volume and microstructural changes develop over time following pediatric TBI and their relation to a measure of processing speed is the focus of this longitudinal investigation. As such, DTI and volumetric changes of the CC in participants with TBI …

Deficits In Adults With Autism Spectrum Disorders When Processing Multiple Objects In Dynamic Scenes, Kirsten O'Hearn, Laura Lakusta, Elizabeth Schroer, Nancy Minshew, Beatriz Luna

Department of Psychology Faculty Scholarship and Creative Works

People with autism spectrum disorders (ASD) process visual information in a manner that is distinct from typically developing individuals. They may be less sensitive to people's goals and, more generally, focus on visual details instead of the entire scene. To examine these differences, people with and without ASD were asked to detect changes in dynamic scenes with multiple elements. Participants viewed a brief video of a person or an inanimate object (the "figure") moving from one object to another; after a delay, they reported whether a second video was the same or different. Possible changes included the figure, the object …

Cognitive Behavioral Therapy For Anxiety Disorders In Youth, Laura D. Seligman, Thomas H. Ollendick

Psychological Science Faculty Publications

Cognitive behavioral therapies (CBTs) have been shown to be efficacious for the treatment of anxiety disorders in children and adolescents. Randomized clinical trials indicate that approximately two-thirds of children treated with CBT will be free of their primary diagnosis at posttreatment. Although several CBT treatment packages have been investigated in youth with diverse anxiety disorders, common core components have been identified. A comprehensive assessment, development of a good therapeutic relationship and working alliance, cognitive restructuring, repeated exposure with reduction of avoidance behavior, and skills training comprise the core procedures for the treatment of anxiety disorders in youth.

Touching A Teddy Bear Mitigates The Negative Effects Of Social Exclusion, Kenneth Tai, Xue Zheng, Jayanth Narayanan

Research Collection Lee Kong Chian School Of Business

There is little empirical research to date that looks at how the deleterious effects of social exclusion can be mitigated. We examined how touching an inanimate object—a teddy bear—might impact the effect of social exclusion on prosocial behavior. Across two studies, we found that socially excluded individuals who touched a teddy bear acted more prosocially as compared to socially excluded individuals who just viewed the teddy bear from a distance. This effect was only observed for socially excluded participants and not for socially included (or control) participants. Overall, the findings suggest that touching a teddy bear mitigates the negative effects …

Ovulation, Female Competition, And Product Choice: Hormonal Influences On Consumer Behavior, Kristina M. Durante, Vladas Griskevicius, Sarah E. Hill, Carin Perilloux, Norman P. Li

Research Collection School of Social Sciences

Recent research shows that women experience nonconscious shifts across different phases of the monthly ovulatory cycle. For example, women at peak fertility (near ovulation) are attracted to different kinds of men and show increased desire to attend social gatherings. Building on the evolutionary logic behind such effects, we examined how, why, and when hormonal fluctuations associated with ovulation influenced women's product choices. In three experiments, we show that at peak fertility women nonconsciously choose products that enhance appearance (e.g., choosing sexy rather than more conservative clothing). This hormonally regulated effect appears to be driven by a desire to outdo attractive …
