Dental Fear, Anxiety, And Phobia – Behavioral Management And Implications For Dentists, Nadya Tsetsova Avramova

Journal of Mind and Medical Sciences

Clinical management of patients with dental fear, anxiety, and phobia could be a major challenge to daily practice of dental professionals. The aim of the current review was to expand the modern consideration with respect to these issues, and therefore to discuss basic approaches and psychological techniques for management of oral health behaviors that should be employed in dentistry. This paper presents detailed description of the characteristics of dentist-patient therapeutic relationship as well as the most used techniques to cope with dental fear, anxiety, and phobia - relaxation techniques, cognitive-behavioral therapy (CBT), hypnosis and melotherapy. We can still argue that …

Low-Dose Psilocybin Enhances Novel Object Recognition But Not Inhibitory Avoidance In Adult Rats, Claire E. Miller, Colin R. Del Valle, Margaret M. Naylor, Heather R. Sparkman, Connor M. Cruea, Rachel E. Rice, Brooke E. Bramlage, Lillianna P. Puppel, Madison L. Brown, Aleece K. Al-Olimat, Elizabeth S. Dietz, Phillip R. Zoladz

ONU Student Research Colloquium

Given the recently renewed interest in using psychedelics to aid in the treatment of psychological disorders, we aimed to examine the impact of psilocybin, a 5-HT_2A agonist, on learning and memory in rodents. Previous work has demonstrated that psilocybin and other 5-HT_2A agonists can enhance fear conditioning, fear extinction, and novel object recognition (NOR). Thus, we predicted that low doses of psilocybin would enhance inhibitory avoidance (IA) and NOR memory. In the first experiment, adult male and female Sprague-Dawley rats underwent step-through IA training (involving 0.45, 0.65, or 1 mA scrambled footshock) and were injected intraperitoneally (i.p.) with …

Tunnel Vision, False Memories, And Intrusive Memories Following Exposure To The Trier Social Stress Test, Chloe N. Cordes, Cassidy L. Pfister, Kayla M. Boaz, Taylor D. Niese, Sydney L. Parker, Kristen E. Long, Mercedes L. Stanek, Matthew S. Risner, John G. Blasco, Koen N. Suzelis, Kelsey M. Siereveld, Shannon B. Carnes, Boyd R. Rorabaugh, Phillip R. Zoladz

ONU Student Research Colloquium

Most research examining the impact of stress on learning and memory has exposed participants to a stressor and measured how it affects learning and memory for unrelated material (e.g., list of words). Such work has been helpful, but it has not been the most translational to the human condition. When considering phenomena such as intrusive memories in post-traumatic stress disorder (PTSD) or an eyewitness's memory for a crime, it is most useful to know what an individual remembers about the stress experience itself, not unrelated information. In prior work, investigators used a modified version of the Trier Social Stress Test …

Impact Of Acute Stress, Sex, And Childhood Maltreatment On Fear Learning And Fear Generalization In A Fear-Potentiated Startle Paradigm, Kayla M. Boaz, Chloe N. Cordes, Cassidy L. Pfister, Taylor D. Niese, Sydney L. Parker, Kristen E. Long, Mercedes L. Stanek, Boyd R. Rorabaugh, Seth D. Norrholm, Phillip R. Zoladz

ONU Student Research Colloquium

Many researchers approach the etiology of trauma-, stressor-, and anxiety-related mental disorders from the perspective of classical conditioning processes gone awry. According to this view, abnormal associative relationships between conditioned and unconditioned stimuli may underlie pathological anxiety and result in unusually intense fear memories or fear memories that cannot be properly extinguished. Recent work has expanded on this view by showing that many psychological disorders involving pathological anxiety are associated with an exaggerated form of stimulus generalization, leading individuals with such disorders to respond with fear and anxiety to a variety of contexts and cues that should not be threatening. …

Psilocybin Prevents Symptoms Of Hyperarousal And Enhances Novel Object Recognition In Rats Exposed To The Single Prolonged Stress Paradigm, Colin R. Del Valle, Heather R. Sparkman, Margaret M. Naylor, Connor M. Cruea, Rachel E. Rice, Claire E. Miller, Brooke E. Bramlage, Lillianna P. Puppel, Madison L. Brown, Aleece K. Al-Olimat, Elizabeth S. Dietz, Phillip R. Zoladz

ONU Student Research Colloquium

Pharmacotherapy for stress-related psychological disorders remains inadequate. Patients who are treated with conventional pharmacological agents frequently report negligeable symptom reduction, and, in most cases, less than 50% experience full remission. Clearly, there is a need for additional pharmaceutical research into both established and novel approaches to alleviate these conditions. Over the past several years, there has been a renewed interest in the use of psychedelics to aid in the treatment of psychological disorders. Several studies have reported promising results in patients with major depression, anxiety disorders, and post-traumatic stress disorder (PTSD) following treatment with psychedelic agents such as lysergic acid …

Childhood-Onset Attention-Deficit/Hyperactivity Disorder Exacerbates Opioid Use Disorder Consequences: Mediation By Impulsive Phenotypes, Liam R. Browning, Ciara Cannoy, Tabitha E. H. Moses, Leslie H. Lundahl Phd, David M. Ledgerwood Phd, Mark K. Greenwald Phd

Medical Student Research Symposium

Background: Attention deficit hyperactivity disorder (ADHD) is highly prevalent and associated with opioid use disorder (OUD). Yet, little is known about the mechanisms by which ADHD (which is a heterogeneous construct/diagnosis) might alter the trajectory of OUD outcomes.

Aim: This cross-sectional study examines relationships between childhood ADHD (inferred as predating substance use) and the extent to which the effects of ADHD on lifetime heroin-use consequences are mediated by foreshortened time perspective and drug-use impulsivity.

Methods: Individuals who report heroin use (N=214) were screened using the Assessment of Hyperactivity and Attention (AHA), Impulsive Relapse Questionnaire (IRQ), Stanford Time Perception Inventory (STPI), …

The Influence Of Early Childhood Parental Feeding Behaviors On Self-Regulation & Food Decision-Making In Young Adults, Natasha Singareddy

CMC Senior Theses

This study used data from a diverse set of undergraduates from the Claremont Colleges to examine the relationship between cognitive control (impulsivity and response inhibition) and self-regulatory ability as an indicator of sustained early childhood parental feeding behaviors in adulthood. In addition, the current study explored if early childhood parental feeding behaviors predicted food decision-making in adulthood as a result of perceived taste and nutritional value of food items. It was hypothesized that heightened impulsivity and impaired response inhibition as measures of cognitive control would correlate to poorer self-regulation, in turn reflecting a particular mode of early childhood parental feeding …

Physiological Responses Regarding Stress And Trauma: The Freeze Response, Emma Arie Von Holten

UNF Graduate Theses and Dissertations

Fight-or-flight is a commonly known response to threatening situations, but the freeze response is another defensive mechanism that might arise in such situations. There is also evidence that exposure to trauma can impact physiological reactions when defensive mechanisms are not required, such as freezing in response to non-threatening situations. The current study aimed to replicate and expand upon a limited number of previous studies on the human freeze response by implementing measurements of postural sway, heart rate, and infrared thermography while valenced images were shown to participants. Ninety-two participants were recruited from the University of North Florida and participants were …

Neurobiology Of Ptsd In Adults And Children: The Impact Of Stress-Induced Brain Abnormalities Across The Lifespan, Catherine Clover

Undergraduate Honors Theses

In the scholarly community, there is disagreement about the effects of PTSD or chronic stress on the brain of adults and children. Though PTSD or chronic stress are known to negatively affect neurobiological structures, specifically due to prolonged glucocorticoid excess, volumetric discrepancies between traumatized and control groups are not unanimously confirmed. This review sought to address the common understandings in academia of the effects of PTSD on the brains of adults and children. Literature on this topic indicated that, in adults, the hippocampus, cingulate gyrus, and prefrontal cortex bilaterally appeared to decrease in gray matter volume and the corpus callosum …

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 …

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 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 …

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 …

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 …

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.

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 …

Suicide Numbers During The First 9-15 Months Of The Covid-19 Pandemic Compared With Pre-Existing Trends: An Interrupted Time Series Analysis In 33 Countries, Jane Pirkis, David Gunnell, Sangsoo Shin, Marcos Del Pozo-Banos, Vikas Arya, Pablo Analuisa Aguilar, Louis Appleby, S. M. Yasir Arafat, Ella Arensman, Murad Khan

Department of Psychiatry

Background: Predicted increases in suicide were not generally observed in the early months of the COVID-19 pandemic. However, the picture may be changing and patterns might vary across demographic groups. We aimed to provide a timely, granular picture of the pandemic's impact on suicides globally.
Methods: We identified suicide data from official public-sector sources for countries/areas-within-countries, searching websites and academic literature and contacting data custodians and authors as necessary. We sent our first data request on 22nd June 2021 and stopped collecting data on 31st October 2021. We used interrupted time series (ITS) analyses to model the association between the …

A Survey Study Of Speech-Language Therapists’ Experiences With Teletherapy At The Onset Of The Covid-19 Crisis, Jason A. Rosas

Dissertations, Theses, and Capstone Projects

The present study aimed to understand how delivering pediatric treatment services via ‘teletherapy’ affected speech-language therapists (SLTs) during the initial outbreak of the COVID-19 pandemic crisis in 2020. SLTs reported on their experiences with the change from in-person to remote service delivery via two national surveys distributed at the start of the pandemic between April 2020 and July 2020. To explain SLTs’ survey responses, this dissertation introduced the Professional Adaptation Model (PA Model). The PA Model facilitated evaluation of the SLTs’ professional environment and the psychological constructs of their professional identity believed to influence the transition to speech-language teletherapy. Specifically, …

Mentors In Violence Prevention: Differential Impacts On Adolescent Bystander Intentions About Bullying, Dating Violence, And Sexual Harassment, Ayla Mapes

Graduate Theses and Dissertations

Bystander approaches are promising interventions that can engage bystanders as prosocial allies to intervene in interpersonal violence situations among youth within school settings. The Mentors in Violence Prevention (MVP) bystander intervention program targets interpersonal violence using a peer-to-peer mentoring model to engage students in a discussion about violence prevention. Research on the MVP program is promising but limited. The current study examined the specificity of MVP intervention effects in two high school samples. The first was a pre/post-test design that included a smaller sample of high school students who participated in the MVP program in the 2013-2014 academic year. The …

An Evaluation Of The Convergent Construct Validity Of The Boldness Inventory Of Psychopathy Using A Five-Minute, 10% Carbon-Dioxide-Enriched Air Challenge, Morgan Alexandra Hill

Graduate Theses and Dissertations

Psychopathy is a constellation of maladaptive interpersonal, affective, and behavioral features, including grandiosity, manipulativeness, emotional detachment, and impulsivity (Hare, 2003). Fearlessness, immunity to stress, self-assurance, and social dominance are considered to be adaptive features of psychopathy. Patrick and colleagues (2009) sought to reconcile differences between opposing conceptualizations of psychopathy by formulating a triarchic model of the condition. One core construct in this model, boldness, captures an ability to remain calm in the face of threat, an appetite for dangerous or risky activities, and an increased tolerance for uncertainty and danger. Boldness is believed to originate from differences in the brain’s …

Simulated Owl Predation During Foraging Differentially Alters Choice And Fear Behavior Between Sex In Rats, Meghan M. Olsen

Research Psychology Theses

Existing research on the predator cue circuit has indicated there are observed differences between sexes of animals either directly or indirectly exposed to a predator stimulus. Exposure increases predator directed attention, and overrides other motivational systems (hunger, pain, reproductive behavior). Little research has explored whether exposure to predation is associated with differential responses to non-predator related decision-making across a variety of tasks. Therefore, understanding the prioritization of motivational states when a predator stressor is present can aid in understanding sex differences in these processes in both adaptative and maladaptive conditions. To determine how repeated exposure to a predator stressor differentially …

Cannabis Sleep Aid Use In Daily College Life: An Intensive Longitudinal Assessment Approach, Patricia A. Goodhines

Dissertations - ALL

Objective: Emerging evidence suggests that college cannabis sleep aid use may increase vulnerability to diurnal impairment, despite proximal sleep-related benefits. In contrast, relatively little is known about proximal precipitants of cannabis sleep aid use in daily college life. The identification of modifiable, situational intervention points preceding cannabis sleep aid use in daily college life is critical to accelerate the development of college harm reduction efforts. This 14-night mixed methods study tested temporal associations of THC-based cannabis sleep aid use with cognitive arousal-based precipitants (consistent with cognitive theory of insomnia) and sleep outcomes.

Method: Daily diary (pre-sleep and waking) and actigraphy …

Effects Of Chronic Stress On Safety Processing And Physiology In The Medial Prefrontal-Amygdala-Basal Forebrain Circuit, Itamar S. Grunfeld

Dissertations, Theses, and Capstone Projects

Chronic stress increases generalization of fear to non-threatening cues, a key symptom in numerous psychiatric mood disorders. However, the mechanisms through which stress impacts safety learning remain poorly understood. To probe the relationship between stress and safety learning, this dissertation employed multiple behaviors, in conjunction with in-vivo multisite physiology during explicit safety and fear discrimination learning. In Chapter 1, I outline the role of chronic stress in driving neurological adaptations that result in generalized fear and highlight how this occurs because of impaired safety cue encoding. In Chapter 2, I show that chronic stress in the form of social defeat …

The Significance Of Sonic Branding To Strategically Stimulate Consumer Behavior: Content Analysis Of Four Interviews From Jeanna Isham’S “Sound In Marketing” Podcast, Ina Beilina

Student Theses and Dissertations
