Literature Review And Proposal: Yoga As Group Exercise Involving Oxytocin Release For Positive Mood Improvement, Rachel Fenton

Honors Projects

A literature review discusses yoga and health involving oxytocin creates the premise for a proposal combining the knowledge of yoga and its health benefits along with oxytocin's potential involvement during group exercise, yoga specifically. The proposed study's results of oxytocin measures and questionnaires have the potential to develop an understanding of the possible impacts of yoga on mood, particularly relationships between group exercise and yoga, which may help develop forms of group exercise or implement group yoga to assist or replace treatment for stress-caused or stress-related disorders.

Social Work Trauma Interventions: Dialectical Behavioral Therapy, Kassie Baumann

Senior Honors Theses

According to Lynne Weilart (2013), in her article on the reasons why people seek out therapy, trauma is the number one reason people attend counseling. Many different trauma-informed approaches are designed specifically to address the consequences of trauma and to facilitate healing. Some of these approaches are as follows: Cognitive Behavioral Therapy (CBT); Dialectical Behavioral Therapy (DBT);Mentalization Based Therapy (MBT); Trauma Systems Therapy (TST); Trauma Assessment Pathway (TAP); and Attachment, Self-Regulation, and Competency (ARC) (de Arellano, Danielson, Ko, & Sprauge, 2008). The effectiveness of each trauma intervention will be examined. DBT is one of these trauma interventions that is growing …

Treating Adhd With Suggestion: Neurofeedback And Placebo Therapeutics, Robert T. Thibault, Samuel Vassière, Jay A. Olson, Amir Raz

Psychology Faculty Articles and Research

Objective: We propose that clinicians can use suggestion to help treat conditions such as ADHD. Methods: We use EEG neurofeedback as a case study, alongside evidence from a recent pilot experiment utilizing a sham MRI scanner to highlight the therapeutic potential of suggestion-based treatments. Results: The medical literature demonstrates that many practitioners already prescribe treatments that hardly outperform placebo comparators. Moreover, the sham MRI experiment showed that, even with full disclosure of the procedure, suggestion alone can reduce the symptomatology of ADHD. Conclusion: Non-deceptive suggestion-based treatments, especially those drawing on accessories from neuroscience, may offer a safe complement and potential …

Effort-Related Decision Making In Comt Variant Mice: Pharmacological Studies And Genetic Susceptibility To Motivational Dysfunction, Suzanne Cayer

Honors Scholar Theses

Effort-related decision making tasks in animals can model motivational symptoms in humans, which are a set of symptoms spanning a multitude of neuropsychiatric disorders, such as major depressive disorder and the negative symptoms of schizophrenia. The present studies aimed to evaluate the effort-related effects of the Val158Met polymorphism of human catechol-methyltransferase (COMT), by testing mice carrying either the human COMT Val (n=8) or Met allele (n=8) with Wild-Type control mice (n=15) by using concurrent FR2 and FR4/pellet choice tasks in a touchscreen operant conditioning apparatus. The Val158Met polymorphism has been repeatedly associated with neuropsychiatric disorders, and the Val allele has …

Memory Complaint Profiles In Dementia Populations Utilizing The Memory Complaints Inventory, Becca N. Johnson

Graduate Theses/Dissertations

The Memory Complaints Inventory (MCI) is a self-report questionnaire developed by Paul Green to provide further effort-related evidence in neuropsychiatric practice. It is comprised of nine subscale scores, in addition to the imbedded Plausible and Implausible symptom validity scales. The current study utilized archival MCI scores in dementia populations to determine the presence of, and difference between, genuine memory impairment profiles in separate subgroups of cognitive impairment. The study sample consisted of 244 adults presenting to an outpatient neuropsychology practice for evaluation of memory impairment. The diagnostic categories of the sample consisted of Alzheimer’s Disease (n = 21), Vascular …

Facebook As A Social Outreach And Advocacy Tool In Intersex/Dsd Groups, Emelie J. Ali Ms

Publications and Research

My project includes a netnography of a Facebook intersex group called Families and Friends of Intersex People. I observed the group’s forms of communication within the group and which topics they discussed. It appears one of the major concerns the group has is the use of nonconsensual, sex assignment surgery on infants to “correct” their body to match a gender identity. I have also discovered a link between being intersex and affiliated with the LGBT+ community. Since the 20th century, intersex people have been stigmatized due to their assumed ability to engage in sexual, same-sex relations. I have concluded that …

The Ush2a Gene: An Analysis Of Ultrasonic Vocalizations In A Mouse Model Of Usher Syndrome Type 2, Kiana R. Akhundzadeh

Honors Scholar Theses

Usher syndrome type 2 is a complex autosomal recessive genetic disorder that is characterized by moderate to severe congenital sensorineural hearing loss, the onset of retinitis pigmentosa in the second decade of life, and in some cases, vestibular dysfunction. Mutations in the USH2A gene account for 85% of cases of type 2. The USH2A gene is responsible for encoding the protein usherin, which has an important role in the development and function of inner ear hair cells and retinal photoreceptors. Until recently, it has been believed that carriers of the USH2A mutation were phenotype free. However, recent data has suggested …

Detecting Suicide Risk From Wristworn Activity Tracker Data Using Machine Learning Approaches, Pallavi Atluri

Electrical Engineering Theses

Suicide is a prevalent cause of death worldwide and depression is a primary concern of many suicidal acts. It is possible that an individual during depression never has any suicidal thoughts at all. On the other hand, some individuals in stable condition with no apparent symptoms of depression feel urges to commit suicide (suicidal ideation). Many such individuals never let anyone know what they are feeling or planning. Suicidal ideation considered an important precursor to suicidal acts.

Detecting the suicide risk in individuals with mood disorders is a major challenge. The current clinical practice to assess suicide risk in these …

Heart Rate Variability: The Effects Of Self-Compassion, John Beckius

Psychology Student Work

Psychologists are interested in self-compassion and its effects on our biopsychological well-being. A common method found throughout much research in assessing this is through heart rate variability. In the present study, we attempt to see whether or not self-compassion has an impact on one’s heart rate variability as a higher HRV indicates one is better able to adapt to stress. Self-compassion was measured through a self-compassion survey and we hypothesized that heart rate variability would then be prone to change across three 5-minute test intervals. We unfortunately found no significant change in HRV predicted by our hypothesis. Given the results …

Heart Rate Variability: Impact Of Neuroticism And Social Isolation, John Beckius

Psychology Student Work

Psychologists are interested in self-compassion and its effects on our biopsychological well-being. A common method found throughout much research in assessing this is through heart rate variability. In the present study, we attempt to see whether or not self-compassion has an impact on one’s heart rate variability as a higher HRV indicates one is better able to adapt to stress. Self-compassion was measured beforehand through an online self-compassion survey that contained subscales measuring neuroticism. We also tested to see if social isolation would have an impact on HRV. Social isolation was implemented through a computer program game titled CyberBall, …

Effects Of Social Isolation On Heart Rate Variabilty, Hailey Tanner, Jason Omann, Nathaniel T. Lutmer, John Beckius

Celebrating Scholarship and Creativity Day (2018-)

The present study looked at the interaction and effects of social isolation on
heart rate variability (HRV). Participants in this study included
undergraduate (N=20) students from St. Johns University and the College
of Saint Benedict. This study included an online survey that measured
neuroticism as well as an online program participants played called
CyberBall. After participants took the neuroticism survey they were
attached to a BioPac machine using electrodes that monitored their heart
rate variability while they played two rounds CyberBall. Heart rate
variability was collected for a total of twenty minutes. We hypothesized that
social isolation would decrease heart …

Aging And The Perception Of Coherent Motion, Lindsey Marie Shain

Masters Theses & Specialist Projects

The aperture problem describes an effect by which a contoured stimulus, moving behind an aperture with both ends occluded, appears to move in a direction perpendicular to its own orientation. Mechanisms within the human visual system allow us to overcome this problem and integrate many of these locally ambiguous signals into the perception of globally coherent motion. In the current experiment, younger and older observers viewed displays composed of either 64 or 9 straight contours, arranged in varying orientations and moving behind circular apertures. Because these lines moved behind apertures, their individual local motions were ambiguous with respect to direction …

The Convergence Of Psychology And Neurobiology In Flavor-Nutrient Learning, Kevin P. Myers

Faculty Journal Articles

Flavor evaluation is influenced by learning from experience with foods. One main influence is flavor-nutrient learning (FNL), a Pavlovian process whereby a flavor acts as a conditioned stimulus (CS) that becomes associated with the postingestive effects of ingested nutrients (the US). As a result that flavor becomes preferred and intake typically increases. This learning powerfully influences food choice and meal patterning. This paper summarizes how research elucidating the physiological and neural substrates of FNL has progressed in parallel with work characterizing how FNL affects perception, motivation, and behavior. The picture that emerges from this work is of a robust system …

Vmpfc Activation During A Stressor Predicts Positive Emotions During Stress Recovery, Xi Yang, Katelyn M. Garcia, Youngkyoo Jung, Christopher T. Whitlow, Kateri Mcrae, Christian E. Waugh

Psychology: Faculty Scholarship

Despite accruing evidence showing that positive emotions facilitate stress recovery, the neural basis for this effect remains unclear. To identify the underlying mechanism, we compared stress recovery for people reflecting on a stressor while in a positive emotional context with that for people in a neutral context. While blood–oxygen-level dependent data were being collected, participants (N = 43) performed a stressful anagram task, which was followed by a recovery period during which they reflected on the stressor while watching a positive or neutral video. Participants also reported positive and negative emotions throughout the task as well as retrospective thoughts …

Findings Of An Effect Of Gender, But Not Handedness, On Self-Reported Motion Sickness Propensity, Ruth E. Propper, Frederick Bonato, Leanna Ward, Kenneth Sumner

Department of Psychology Faculty Scholarship and Creative Works

Discrepant input from vestibular and visual systems may be involved in motion sickness; individual differences in the organization of these systems may, therefore, give rise to individual differences in propensity to motion sickness. Non-right-handedness has been associated with altered cortical lateralization of vestibular function, such that non-right-handedness is associated with left hemisphere, and right-handedness with right hemisphere, lateralized, vestibular system. Interestingly, magnocellular visual processing, responsible for motion detection and ostensibly involved in motion sickness, has been shown to be decreased in non-right-handers. It is not known if the anomalous organization of the vestibular or magnocellular systems in non-right-handers might alter …

Biological Signatures Of Emotion Regulation In Children, Sarah Myruski

Dissertations, Theses, and Capstone Projects

Emotion regulation (ER) is a key predictor of positive adjustment throughout the lifespan. Despite decades of research on discrete ER strategy use, ER may be more appropriately measured in terms of the breadth of emotional range, or the degree to which one can flexibly modulate emotional responses. Yet little is known about ER flexibility in childhood. Also, given the crucial role of caregiver support in children’s emotional lives, ER may be most accurately measured in developmentally appropriate and ecologically valid social contexts. Further, few developmental studies have capitalized on the growing evidence base surrounding biological signatures of ER. This study …

Neural Hypervigilance In Trauma-Exposed Women, Seungyeon A. Yoon

Dissertations, Theses, and Capstone Projects

Trauma-exposed people often experience hypervigilance, which is a tonic condition of elevated alertness and excessive scanning for potential threat. A cardinal feature of hypervigilance is that no actual threat is needed to evoke or maintain the over-alertness and heightened affective response. However, most neuroimaging research in trauma to date has only focused on reactivity to an actual threat. Thus, the overarching aim of this dissertation was to investigate neural signatures and salivary markers of post-trauma hypervigilance in the absence of threat that can cause impairment in daily functioning and contribute to developing other trauma-related symptoms such as heightened threat reactivity. …

Analysis Of Endocrine Response To Perceived Difference In Cross-Cultural Interactions, Carole Woolford-Hunt, Marlene Murray, Tevni Grajales Guerra, Kristina Beenken-Johnson

Faculty Publications

We live in a world where awareness of ethnic and cultural diversity is an ever increasing reality. Business and education turn to the social sciences to inform them about how to manage and optimize cross-cultural interactions. Although much research has been done on the impact of cross-cultural interactions on a wide range of variables, one less researched area is the endocrine response to cross-cultural interactions. In this study we set out to investigate the endocrine response to cross cultural interactions and the impact of these interactions on perceived differences. To do so we measured the pre and post levels of …

The Influence Of A Positive Or Negative Mindset On Affect And Heart Rate Variability, Alexa Ronayne

All College Thesis Program, 2016-2019

The purpose of this study was to see whether the induction of a positive or negative mindset could influence measures of health and happiness, specifically heart rate variability and affect. 43 participants completed two short writing exercises intended to place them in either a positive or a negative mindset. During the entirety of the study, I measured their heart rate and calculated the variability between beats. Participants reported their affect before and after the manipulation. The results showed a clear relationship between mindset condition and heart rate variability and a possible link between mindset and affect. The positive mindset condition …

Arousal Reappraisal And Interoceptive Awareness: How Awareness Of Bodily Changes Facilitates Heightened Performance And Ability To Reappraise, Wyndham Chalmers

All College Thesis Program, 2016-2019

The physiological arousal induced by a stressful situation has historically been viewed as bad; however, recent research has challenged this perspective, arguing that stress-related arousal can be beneficial. Arousal reappraisal is a coping technique that encourages individuals to reinterpret their physiological stress response as a means to help improve performance. Conversely, suppression, a common, yet ineffective coping technique, involves the active effort to stop oneself from expressing an emotional behavior. The current research examined the relationship between coping techniques and interoceptive awareness (IA), the degree to which individuals are aware of their own physiological changes. Comparing arousal reappraisal to both …
