Do Gender, Anxiety Sensitivity Level, And Timing Of Anxiety Sensitivity Assessment Predict Heart Rate Variability?, Jordan Sieja Jan 2021

Do Gender, Anxiety Sensitivity Level, And Timing Of Anxiety Sensitivity Assessment Predict Heart Rate Variability?, Jordan Sieja

Master's Theses and Doctoral Dissertations

Anxiety sensitivity (AS), or the fear/belief that anxiety symptoms and sensations will have negative outcomes, is a strong predictor of future psychopathology. AS is divided into three factors: physical, cognitive, and social. Reduced heart rate variability (HRV), or the variation in intervals between heartbeats, is associated with various psychological disorders. Current research findings disagree as to whether AS predicts HRV outcomes. The present study sought to examine data from a previous research project as results of relationships between AS and HRV were contrary to expectations. The current study examined potential predictors of HRV, such as the relationship between high-frequency (HF) …


Examining The Effects Of Stress And Age On Neural Reward Processing: Considerations For The Role Of Individual Differences In Autonomic Reactivity, William Mccuddy Jul 2019

Examining The Effects Of Stress And Age On Neural Reward Processing: Considerations For The Role Of Individual Differences In Autonomic Reactivity, William Mccuddy

Dissertations (1934 -)

Acute stress is unavoidable and may hinder basic reward processing underlying adaptive decision-making. Additionally, older adults may be at an increased risk of poor decision-making after exposure to acute stress due to age-related changes in cognitive and autonomic functioning. The current study assessed the influence of acute stress, autonomic reactivity, and age on a simple behavioral task during fMRI. Specifically, old and young adults completed a basic reward processing paradigm (i.e., where participants received monetary rewards and punishments) after exposure to acute stress (i.e., social evaluative cold pressor) or control procedure between-subjects. In the young group, differential responses for monetary …


Pilot Study: Heart Rate Variability Analysis And Mental Health Outcomes In University Female Hockey Players, Kaitlyn Jacobs Aug 2018

Pilot Study: Heart Rate Variability Analysis And Mental Health Outcomes In University Female Hockey Players, Kaitlyn Jacobs

Electronic Thesis and Dissertation Repository

Exercise improves anxiety and depression, both of which are associated with impaired autonomic regulation of heart rate (HR). In turn, HR variability (HRV) is a reliable physiological indicator of external stressors. The following research tested the hypothesis that HRV is indicative of chronic resilience towards mental stress in female varsity hockey players. Seventeen varsity hockey players (HOCK, age 21 ± 1.5) and fifteen healthy controls (CTRL, age 21 ± 2.2) at Western University participated three times throughout a 7-month season. Participants completed questionnaires (brief resilience scale, BRS; generalized anxiety scale, GAD-7; mental health inventory, MHI; visual analog scale, VAS; short …


Effects Of A 2-Week Exercise Intervention On Heart Rate Variability In Individuals With Low And High Anxiety Sensitivity, Hannah M. Kotarski Jan 2018

Effects Of A 2-Week Exercise Intervention On Heart Rate Variability In Individuals With Low And High Anxiety Sensitivity, Hannah M. Kotarski

Theses and Dissertations

Anxiety Sensitivity (AS), the belief that anxiety-related sensations may have harmful implications, can alter autonomic nervous system (ANS) function. Exercise has previously been shown to reduce AS; however, the effects of an exercise intervention on heart rate variability (HRV), a measure of ANS function, has not been evaluated in individuals with high AS. This study sought to 1) compare resting HRV in individuals with either low (LAS) or high AS (HAS) and 2) evaluate the effects of a 2-week exercise intervention on HRV and AS. Using the Anxiety Sensitivity Index (ASI-3), participants were identified as LAS (n=9; ASI-3=5.89±1.39) or HAS …


Deep Brain Stimulation For Parkinson's Disease: An Investigation Of Post-Surgical Self-Regulation And Executive Functioning, Hannah L. Combs Jan 2016

Deep Brain Stimulation For Parkinson's Disease: An Investigation Of Post-Surgical Self-Regulation And Executive Functioning, Hannah L. Combs

Theses and Dissertations--Psychology

Parkinson’s Disease (PD) is a common neurodegenerative disorder that attacks the basal ganglia and contributes to a range of motor, cognitive, and behavioral impairments (e.g., tremor, rigidity, and executive dysfunction). This dysfunction may contribute to self-regulatory impairment across several domains, including cognitive skills, thought processes, and emotion. Deep Brain Stimulation (DBS) is a neurosurgical procedure that allows for direct and reversible manipulation of brain activity in patients with PD. The procedure is growing in popularity and is commonly used as an adjunct or in some instances an alternative to dopaminometic medications. Preliminary studies suggest mild executive dysfunction follows DBS but …


The Relationship Between Vagal Tone, A Marker Of Parasympathetic Activity, And Pro-Social Behavior, Emily A. Goodlin Jan 2015

The Relationship Between Vagal Tone, A Marker Of Parasympathetic Activity, And Pro-Social Behavior, Emily A. Goodlin

Scripps Senior Theses

Vagal tone, a measure of parasympathetic activity via the vagus nerve, is known to be associated with positive emotion because it promotes social engagement and self-soothing behavior. Heart rate variability (HRV), especially high frequency oscillation, is a direct measure of vagal tone, and has been used in previous studies to test the correlation between vagal tone and positive emotion. This study aims to determine if the two major oscillations of heart rate variability, high frequency (HF-HRV) and low frequency (LF-HRV) can predict pro-social behavior, which is classified as giving donations to charities. Baseline LF- and HF-HRV levels were recorded, and …


Self-Regulation In Older Adults: The Prioritization Of Emotion Regulation, Daniel R. Evans Jan 2014

Self-Regulation In Older Adults: The Prioritization Of Emotion Regulation, Daniel R. Evans

Theses and Dissertations--Psychology

Despite having fewer cognitive resources, older adults regulate their emotions as well as, if not better than, younger adults. This study aimed to (1) test the limits of older adults’ emotion regulation capacity and (2) gain a better understanding of how older adults use their more limited resources to regulate their emotions. Participants included 48 healthy older adults aged 65-85 from the community and 50 healthy younger adults aged 18-25 from the student population. They were randomly assigned to one of four experimental groups involving an initial activity that was high or low in self-regulatory demand followed by a test …


Physiological And Evaluative Differences Between Internet-Based And In-Person Interview Techniques, Joseph R. Castro Aug 2013

Physiological And Evaluative Differences Between Internet-Based And In-Person Interview Techniques, Joseph R. Castro

Psychology - Theses

A growing trend in job selection is the use of automated online interviews as a cheap and easy tool for gaining many applicants. The use of the Internet for selection interviews may have ramifications on the interviewer's perception of the candidate's personality and performance. It can also affect the candidate's physiological responses and ability to process information. Two types of interviews were conducted, a face-to-face interview and a computer-mediated interview. Comparisons between the two conditions were made for ratings of performance, the accuracy of an observer's estimation of the participant's personality, cognitive interference, and physiological reactivity. There was no difference …


Relationships Among Pain Threshold, Self-Regulation, Executive Functioning, And Autonomic Activity: A General Inhibitory System Perspective, Ian Andres Boggero Jan 2013

Relationships Among Pain Threshold, Self-Regulation, Executive Functioning, And Autonomic Activity: A General Inhibitory System Perspective, Ian Andres Boggero

Theses and Dissertations--Psychology

Chronic pain patients have poorer pain inhibition, self-regulatory ability, executive functioning and autonomic inhibition than those without pain, supporting the view that suppressing pain is mentally taxing. In the current study, an alternate explanation was proposed; namely, that pain inhibition, self-regulation, executive functions, and heart rate variability (HRV) are all controlled by the same general inhibitory system. To test this hypothesis, participants came into the laboratory for three sessions. At the first session, individual differences in pain thresholds, self-regulatory strength, executive functioning, and HRV were measured. At the second and third sessions, self-regulatory persistence and within-session changes in pain thresholds …


Executive Deficits In Amyotrophic Lateral Sclerosis: Examining The Consequences Of Self-Regulatory Impairment On Quality Of Life, Abbey R. Roach Jan 2010

Executive Deficits In Amyotrophic Lateral Sclerosis: Examining The Consequences Of Self-Regulatory Impairment On Quality Of Life, Abbey R. Roach

University of Kentucky Doctoral Dissertations

Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease that attacks the motor system and contributes to a range of cognitive and behavioral impairments (e.g., behavioral and emotional disinhibition, planning and problem solving difficulties, impulsivity, attention, and personality change). This executive dysfunction may contribute to selfregulatory impairment across several domains, including cognitive skills, thought processes, emotion regulation, interpersonal skills, and physiology, that may be crucial to the quality of life (QOL), or well being, of patients and their caregivers. Given the relentless course and prognosis of ALS, palliative treatments for ALS should target the full range of self-regulatory deficits. Thirty-seven …
