The Role Of Dopamine Signaling In Prairie Vole Peer Relationships, Nicole S. Lee, Annaliese K. Beery

Psychology: Faculty Publications

Dopamine signaling mediates the formation of some types of social relationships, including reproductive pair bonds in the socially monogamous prairie vole (Microtus ochrogaster). In addition to these pair bonds with mates, prairie voles demonstrate selective preferences for familiar same-sex peers. The dependence of peer relationships on dopamine signaling has not been tested, and the mechanisms supporting these relationships may differ from those underlying pair bonds. We examined the effects of pharmacological manipulations of dopamine signaling on peer partner preference and socially conditioned place preference in female prairie voles. Haloperidol blockade of dopamine receptors at multiple doses did not alter selective …

Integrating Storytelling Into The Theory And Practice Of Contextual Behavioral Science, Carter H. Davis, Brandon A. Gaudiano, Louise Mchugh, Michael E. Levin

Psychology Student Research

The practice of generating and interpreting stories can be examined through a behavioral lens and has many potential implications for clinical practice. However, storytelling has for the most part yet to be integrated into the field of contextual behavioral science (CBS). A bedrock of human culture, storytelling has influenced both individual behavior and intergroup cooperation for millennia. Basic principles of relational frame theory, such as those pertaining to coherence, perspective-taking, and the transformation of stimulus function, may help to reveal how stories derive their psychological impact. In turn, understanding storytelling from a CBS perspective can facilitate the broader integration of …

A Comprehensive Study To Delineate The Role Of An Extracellular Vesicle-Associated Microrna-29a In Chronic Methamphetamine Use Disorder, Subhash Chand, Austin Gowen, Mason Savine, Dalia Moore, Alexander Clark, Wendy Huynh, Niming Wu, Katherine Odegaard, Lucas Weyrich, Rick A. Bevins, Howard S. Fox, Gurudutt Pendyala, Sowmya V. Yelamanchili

Department of Psychology: Faculty Publications

Extracellular vesicles (EVs), which express a repertoire of cargo molecules (cf. proteins, microRNA, lipids, etc.), have been garnering a prominent role in the modulation of several cellular processes. Here, using both non-human primate and rodent model systems, we provide evidence that brain-derived EV (BDE) miRNA, miR- 29a-3p (mir-29a), is significantly increased during chronic methamphetamine (MA) exposure. Further, miR-29a levels show significant increase both with drug-seeking and reinstatement in a rat MA self-administration model. We also show that EVassociated miR-29a is enriched in EV pool comprising of small EVs and exomeres and further plays a critical role in MA-induced inflammation and …

Do You Copy? Post-Traumatic Stress Disorder, Auditory Processing, And Heart Rate Variability, Lyndsey Johnson

UNF Graduate Theses and Dissertations

Self -report measures used in PTSD research have the potential to limit the degree of symptom severity in military veterans, especially as there is often underreporting in this population (Kline, Falca-Dodson, Susner et al., 2010). Polyvagal Theory provides a framework assessing if physiological measures can tap into PTSD Symptomology (Porges, 1995). It is therefore hypothesized that lower scores on auditory processing tests will be positively correlated with higher scores on Stress and PTSD measures. Additionally, it is thought that lower scores on auditory processing tedts as well as higher scores on PTSD and Stress Measures will be positively correlated with …

Inside The Zoo: Captive Giraffes’ Changes In Social Ties Throughout Membership Variations, Morgan Paige Howard

UNF Graduate Theses and Dissertations

Many animals live in gregarious, fission-fusion societies where group size and composition are continually changing. Despite this, many studies have suggested that captive animals are capable of maintaining long term social bonds with others. In captive giraffes, effects on their social bonds during membership transitions have not been studied thoroughly, however, prior research does show that social bonds are a defining factor in non-captive animals. Captive giraffe social network patterns were investigated at the Jacksonville Zoo and Botanical Gardens using all occurrence behavioral data. Based on previous research, I hypothesized that when one of the individuals in the group was …

Want To Hookup?: Sex Differences In Short Term Mate Attraction Tactics, T. Joel Wade, Maryanne L. Fisher, Catherine Salmon, Carly Downs

Faculty Journal Articles

While a great deal of psychological research has been conducted on sex-specific mate choice preferences, relatively little attention has been directed toward how heterosexual men and women solicit short-term sexual partners, and which acts are perceived to be the most effective. The present research relied on an act nomination methodology with the goal of determining which actions are used by men and women to solicit a short-term “hook-up” partner (study 1) and then determine which of these actions are perceived as most effective by men and women (study 2). Using sexual strategy theory, we hypothesized that actions that suggest sexual …

Primed For Addiction: A Critical Review Of The Role Of Microglia In The Neurodevelopmental Consequences Of Adolescent Alcohol Drinking, Jennifer K. Melbourne, Cassie M. Chandler, Catherine E. Van Doorn, Michael T. Bardo, James R. Pauly, Hui Peng, Kimberly Nixon

Psychology Faculty Publications

Alcohol is one of the most widely used recreational substances worldwide, with drinking frequently initiated during adolescence. The developmental state of the adolescent brain makes it vulnerable to initiating alcohol use, often in high doses, and particularly susceptible to alcohol-induced brain changes. Microglia, the brain parenchymal macrophages, have been implicated in mediating some of these effects, though the role that these cells play in the progression from alcohol drinking to dependence remains unclear. Microglia are uniquely positioned to sense and respond to central nervous system insult, and are now understood to exhibit innate immune memory, or “priming,” altering their future …

Effects Of Social Isolation On Perineuronal Nets In The Amygdala Following A Reward Omission Task In Female Rats, Dolores B. Vazquez-Sanroman, G. Arlington Wilson, Michael T. Bardo

Psychology Faculty Publications

Negative urgency is a facet of impulsivity associated with negative affect and risky behavior that may involve the amygdala. The current study determined if social isolation during development alters negative urgency and c-Fos activity in the basolateral amygdala (BLA). Female Sprague-Dawley rats were raised in an isolated condition (IC), a standard social condition (SC), or an enriched condition (EC) and then were tested for locomotor activity, novelty place preference, and negative urgency using a reward omission task. Following performance on the reward omission task, the brains were analyzed for c-Fos expression in Ca2+ /calmodulin kinase II (CaMKII) and calbindin (CB) …

Effects Of The Glucocorticoid Receptor Antagonist Pt150 On Stress-Induced Fentanyl Seeking In Male And Female Rats, Lindsey R. Hammerslag, Emily D. Denehy, Benjamin A. Carper, Tracy L. Nolen, Mark A. Prendergast, Michael T. Bardo

Psychology Faculty Publications

Rationale Opioid use disorder (OUD) is highly comorbid with stress-related disorders, and stress can serve as a trigger for reinstatement of drug seeking. Glucocorticoid receptor (GR) antagonists such as mifepristone (RU-486) may be effective against stress-induced drug seeking. In the current study, PT150 (formerly ORG-34517), a more selective GR antagonist, was tested using two models of stress-induced drug seeking, namely footshock and yohimbine.

Methods Adult male and female Sprague-Dawley rats were trained to self-administer fentanyl (2.5 μg/kg/infusion, i.v.) in a model of escalation. Rats then received 7 days of abstinence, followed by extinction; PT150 (0, 50 or 100 mg/kg in …

Developing A Nomological Network To Incorporate Learned Helplessness Into Industrial-Organizational Psychology, Nicholas Kovacs

Browse all Theses and Dissertations

Employees are facing personal traumas, higher stress, and work pressures that are likely to result in both short- and long-term impacts. To mitigate these negative impacts, organizations should focus on applying research related to employees’ responses to trauma and stress. Learned helplessness, which is well-established within clinical psychology and less established within the industrial-organizational literature, occurs as a direct response to perceived control over trauma and could thus relate to the ability to overcome trauma. In relation to control-related constructs, industrial-organizational researchers have focused on resilience, hardiness, and work locus of control (LOC). However, each of these constructs account for …

Comparison Of Differential Effects Of Interpolated And Intermittent Reinforcement On Extinction Resistance: A Simulated Study, Cara D. Baxter

Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

Schedules of reinforcement explain when a reinforcer may be delivered. Among the different schedules exists continuous (CRF), intermittent (INT), and extinction (EXT). When employing a CRF, reinforcement is delivered following every occurrence of the target response. An INT schedule includes varying the delivery of reinforcement. While both of these schedules include the delivery of reinforcement, EXT means that reinforcement is no longer delivered for the target response (Lee & Belfiore, 1997). Studies have shown that behaviors may be less resistant to extinction if moved from an INT schedule to a CRF schedule than if EXT followed the INT schedule alone. …

The Relationship Between Insomnia, Sleep Continuity Disturbance, Sleep-Related Daytime Dysfunction, Problem Endorsement, And Aging In A Community-Based Sample, Julia T. Boyle

PCOM Psychology Dissertations

Although older adults experience greater difficulty initiating sleep, maintaining sleep, or waking up earlier than intended, they are less likely to report that they perceive this to be a problem. The discordance between sleep disorder symptoms and the reported perception that they are troubling is unusually prevalent among older adults. This may be problematic, in that individuals who do not perceive their sleep continuity disturbances (SCDs; difficulty falling asleep, staying asleep, or waking up earlier than intended) to be problems are less likely to seek treatment. Untreated SCD has been shown to be a risk factor for the development or …

The Role And Implications Of Executive Functions During The Transition To Middle School, Susan Niznik

PCOM Psychology Dissertations

The current study analyzed the relationship between executive functions and academic performance in middle school. In particular, this study analyzed the relationship between BRIEF Index and Scale scores that were compiled on a group (N = 54) of seventh graders by two seventh-grade ELA teachers and the students’ final grades in ELA, Math, Science, and Social Studies. The results showed statistically significant correlations between most of the BRIEF Indexes and Scales and the final grades, with the Metacognitive Scales showing the highest correlations. In contrast, the results showed much higher incongruence index values than expected, given the high correlations that …

This study expands the COVID-19 and Latino Immigrants in Rural California (CLIMA) Study at UC Merced by exploring how the mental health of young adult Latinos in rural CA has been affected by the COVID-19 pandemic and comparing the experiences of US-born Latinos to those of Latino immigrants to investigate an Immigrant Health Paradox. A convergent mixed methods design was first employed whereby qualitative and quantitative data was collected concurrently, and then merged. Then, the data collected from young adult Latinos was compared to that from Latino immigrants collected by CLIMA Study to explore the Immigrant Health Paradox in the …

Mapping Specific Mental Content During Musical Imagery, Mor Regev, Andrea R. Halpern, Adrian Owen, Aniruddh Patel, Robert J. Zatorre

Faculty Journal Articles

Humans can mentally represent auditory information without an external stimulus, but the specificity of these internal representations remains unclear. Here, we asked how similar the temporally unfolding neural representations of imagined music are compared to those during the original perceived experience. We also tested whether rhythmic motion can influence the neural representation of music during imagery as during perception. Participants first memorized six 1-min-long instrumental musical pieces with high accuracy. Functional MRI data were collected during: 1) silent imagery of melodies to the beat of a visual metronome; 2) same but while tapping to the beat; and 3) passive listening. …

Individual Differences In Social Responsiveness, Social Experiences, And Oxytocin System Genetic Variation In Depression Symptom Severity, Grace Sullivan

Department of Psychology: Dissertations, Theses, and Student Research

Social experiences including discrimination, low social support, and interpersonal conflict are reliable predictors of depression symptom severity (Costello, 1982; Monroe, Rohde, Seeley, & Lewinsohn, 1999; Phifer & Murrell, 1986). However, individual differences may buffer against or exacerbate risk (Pluess & Belsky, 2015). A more holistic and dimensional approach, in line with modern perspectives on mental health (Kircanski, LeMoult, Ordaz, & Gotlib, 2017), requires an investigation of individual differences that moderate associations of positive and negative social experiences with depression symptom severity. This dissertation assesses relative contributions of social experiences (low social support, discrimination, childhood trauma, and sexual objectification) to variation …

Child Abuse Reporting By Mandated Reporters In Schools, Kliche Adebanjo

Walden Dissertations and Doctoral Studies

Child maltreatment has proven to be a mainstream issue in the United States, with millions of children being referred to state welfare systems for investigation or alternative response intervention. Research has identified mandated reporters as being responsible for reporting the majority of these cases. Amongst those identified as mandated reporters, education personnel refer the greatest number of children for suspicion of child abuse or neglect, partly because of their ongoing contact daily; however, many of the cases they report are unsubstantiated. Past research findings have concluded that mandated reporters in schools lacked proper child abuse training. The purpose of this …

Relationship Between Social Support And Childhood Trauma On Resilience, Carol Krieger

Walden Dissertations and Doctoral Studies

People who have not overcome childhood trauma and who have developed mental illnesses have difficulties dealing with life challenges. The purpose of this quantitative study used a correlational design to test any relationship between childhood trauma experience levels and resilience against life challenges in adulthood. The theoretical framework used for this study was Barnes’ social support theory. Data were collected from 104 participants over a 7-week period. Participants voluntarily answered the ACE questionnaire, 2-way support scale, and resilience scale. Key results indicate that people with mental illness who receive social support are positive impacted by that support. Receiving adequate levels …

Time Spent Gaming And Marital Quality: The Effect Of Mmorpgs, Kimberly J. Walker

Walden Dissertations and Doctoral Studies

It is not known if, or to what degree, time spent playing massive multi online roleplaying games (MMORPGs) and adult attachment style affect marital quality. This study attempts to deliver a clearer image about the statistical links between MMORPGs and marital quality to better understand how MMORPGs can affect this relational area. Attachment theory is the theoretical model used in this study. The Hayes mediation analysis was used to answer the research questions. However, correlations were performed initially, to evaluate the suitability of the mediation analysis. The 240 respondents were selected using a convenience sampling approach, through the use of …

Volunteer Motivation Of Individuals In Rural Pacific Northwest, Lenea Kindred Pierzchanowski

Walden Dissertations and Doctoral Studies

Volunteering is a selfless social action in which an individual chooses to participate through personal motivations. These actions of public service are a combination of need-based vacancies within organizations and unpaid compensation for filling those needs. The purpose of this research was to identify motivational attributes of individuals who volunteer in the identified rural area using one-on-one semi-structured interviews through the lens of the volunteer process model, in addition to the social identity, ecological, and social capital theories. The 15 participants for this study were over the age of 18, fluently spoke and read English, and had been a volunteer …

Evaluating Antecedents To Treatment Success In Juveniles With Sexually Problematic Behavior, Alexandra P. Pappas

PCOM Psychology Dissertations

The impact of rape and other sexual offenses represents a major problem in society and can lead to chronic and harmful physical, psychological, and social consequences. Juveniles (younger than 18 years old) account for 20% of sexual offense arrests in the United States, with 96% of reported cases committed by male perpetrators. Risk indicators and characteristics of juveniles who sexually offend include demographic factors (e.g., history of sexual abuse), personality factors (e.g., antisocial behavior), and below average intelligence and cognitive functioning. Treatment of problematic sexual behavior in juveniles varies in intensity, structure, and level of supervision, though research investigating unsuccessful …

Medical Knowledge As A Recalcitrant Epistemological System: An Application Of Standpoint Epistemology In The Analysis Of Marginalization Within U.S Healthcare, Abby Deshazo

CMC Senior Theses

Research on healthcare disparities outside the field of epistemology tend to miss the true origins of oppressions imposed on marginalized individuals by the U.S healthcare system. This happens because of the false belief that these oppressions are reducible to social or political oppressions. By employing the perspective of a standpoint epistemologist, we can better identify the origins of these oppressions and subsequently consider more appropriate solutions. The standpoint epistemologist’s perspective (1) provides an intuitive case for the role individuals’ schemas play in the evaluation of what healthcare professionals know; (2) situates medical knowledge within epistemology, leading us to …

A Foray Into The Interval Timing Capabilities Of Tufted Capuchin Monkeys (Cebus [Sapajus] Apella), Gryff Griffin

Honors Theses

Time is a critical part of life and timing on the range from milliseconds to minutes has proven to be critical for several behaviors such as foraging and movement. While the exact neurological structures of interval timing are currently undefined, several studies have been completed comparing the interval timing capabilities of humans and nonhuman primates. However, these studies have unanimously utilized members of Macaca, which limits the abilities for researchers to make apt comparisons between humans and all nonhuman primates. This study sought to investigate whether tufted capuchins (Cebus [Sapajus] apella) have the capability to measure time …

Uncovering Object Categories In Infant Views, Naiti S. Bhatt

Scripps Senior Theses

While adults recognize objects in a near-instant, infants must learn how to categorize the objects in their visual environments. Recent work has shown that egocentric head-mounted camera videos contain rich data that illuminate the infant experience (Clerkin et al., 2017; Franchak et al., 2011; Yoshida & Smith, 2008). While past work has focused on the social information in view, in this work, we aim to characterize the objects in infants’ at-home visual environments by modifying modern computer vision models for the infant view. To do so, we collected manual annotations of objects that infants seemed to be interacting within a …

Comparing Common Procedures Used To Manipulate Reinforcer Magnitude, Michael Steele Yencha

Graduate Theses, Dissertations, and Problem Reports (ETD)

Reinforcer magnitude is one of several parameters of reinforcement. In the present study, it referred to the quantitative value of the reinforcer in terms of duration of access to a finite supply of grain pellets. Pigeons responded on concurrent-chain schedules earning one of several reinforcer durations depending on response allocation and experimental conditions. Experiment 1 consisted of relatively long reinforcer durations available for completing one chain compared to relatively short durations available on the other. Response allocation in the initial link determined the reinforcer duration, but responses in the terminal link produced no change in the upcoming reinforcer. This arrangement …

The Effects Of Priming On Framing Bias: An Integrative Study Examining Mortality Salience, Self-Affirmation, And Emotional Intelligence, Kyle Klaassen

All Master's Theses

The framing effect is a cognitive bias in which the way a choice is presented influences decision-making. Individuals avoid risk when a scenario or choice is presented in a positive light or as a gain (e.g., lives will be saved, money will be gained). In contrast, because losses are more salient than gains, people will select more risky options in order to avoid potential losses when choices are framed negatively (e.g., lives lost, money lost). Another method of influencing decision-making is priming in which interactions with a specific stimulus predisposes individuals toward certain behaviors or thoughts. The current study examined …

Corticostriatal Pathway Inactivation And Connections To Associative Learning With Nicotine Stimulus In Rats, Anna Kalinowski

Honors Theses and Capstones

The main concern of this study is looking into the neural mechanisms of associative learning with a nicotine stimulus. The goal of this study was to find out if inactivating the corticostriatal pathway through DREADDs (Designer Receptors Exclusively Activated by Designer Drugs) inhibited goal-tracking behavior in rats. In this experiment, rats underwent two surgeries. One was to inject DREADDs into the infralimbic cortex and the other in the dorsomedial caudate-putamen (dmCPu). Rats were initially trained on levers through water deprivation. Once they reached the criterion, they moved on to the self-administration phase. After the rats were trained in self-administration sessions …

Utilizing Virtual Reality Therapy In The Treatment Of Generalized Anxiety Disorder In College Counseling Centers, Kaitlyn Barker

Psychology Doctoral Specialization Projects

Anxiety is a leading mental health concern among college students. A growing number of students are presenting with symptoms of generalized anxiety disorder (GAD), which is one of the most common anxiety disorders. As demands for treatment of this disorder increase, counseling centers are also facing limited funding for providing such services. The result is that there is a need to provide more cost effective, and empirically supported approaches to treatment. Therefore, implementing a program that will allow students to utilize already accessible technology to teach themselves how to combat anxiety is merited. Virtual reality therapy (VRT), is one such …
