A Randomized Controlled Trial Of Psychological Outcomes Of Mobile Guided Resonant Frequency Breathing In Young Adults With Elevated Stress During The Covid-19 Pandemic, Al Amira Safa Shehab Sep 2021

A Randomized Controlled Trial Of Psychological Outcomes Of Mobile Guided Resonant Frequency Breathing In Young Adults With Elevated Stress During The Covid-19 Pandemic, Al Amira Safa Shehab

Dissertations, Theses, and Capstone Projects

Deep breathing practices have shown promise in reducing stress, anxiety, and depression in different populations, including young adults. Specifically, resonant frequency breathing can exert an impact on stress response systems through the vagus nerve and the hypothalamo-pituitary-adrenal (HPA) axis. This may induce reductions in stress and improvement in emotion regulation. Young adults, including college students, tend to be at a higher risk for psychological distress, as they face several psychosocial challenges. The COVID-19 pandemic has imposed new and unique stressors that resulted in higher levels of stress and emotional symptoms and it has been shown that this may have placed …


The Impact Of A Single Session Of Mindfulness Meditation On The Attentional Blink In Non-Meditators, Arielle L. Klopsis Jun 2020

The Impact Of A Single Session Of Mindfulness Meditation On The Attentional Blink In Non-Meditators, Arielle L. Klopsis

Dissertations, Theses, and Capstone Projects

Attentional resources are limited therefore a stimulus can go undetected if it closely follows another target by 200-500ms. This phenomenon is known as the attentional blink. Mindfulness meditation has been shown to be beneficial in target detection and in decreasing the attentional blink. Since there is no standard for the type of meditation or duration of practice that leads to attention benefits, this study compares the two most popular types of meditation in a group of non-meditators: focused attention and open monitoring meditation. This study utilized an attentional blink paradigm to measure if a single session of mindfulness meditation can …


Emotion Processing Deficits In Psychopathy: Does Cueing To Relevant Facial Features Increase Cognitive And Emotional Empathy?, Shawn E. Fagan Sep 2019

Emotion Processing Deficits In Psychopathy: Does Cueing To Relevant Facial Features Increase Cognitive And Emotional Empathy?, Shawn E. Fagan

Dissertations, Theses, and Capstone Projects

Psychopathy is a multifaceted disorder characterized by a lack of cognitive and emotional empathy. The traditional model of psychopathy divides the disorder into two factors: Factor 1 consists of the interpersonal and affective traits of psychopathy while Factor 2 measures antisocial behaviors and lifestyle choices. The attention-to-the-eyes hypothesis argues that psychopathic individuals have impaired emotion recognition (specifically for fear) due to deficits in orienting attention to salient facial features like the eyes. Psychopathic individuals also display blunted autonomic responding to emotional stimuli, though whether this is due to attention-orienting deficits remains to be clarified. The present project investigated whether empathy-related …


The Neurophysiology Of Intersensory Selective Attention And Task Switching, Jeremy W. Murphy Feb 2015

The Neurophysiology Of Intersensory Selective Attention And Task Switching, Jeremy W. Murphy

Dissertations, Theses, and Capstone Projects

Our ability to selectively attend to certain aspects of the world and ignore others is fundamental to our day-to-day lives. The need for selective attention stems from capacity limitations inherent in our perceptual and cognitive processing architecture. Because not every elemental piece of our environment can be fully processed in parallel, the nervous system must prioritize processing. This prioritization is generally referred to as selective attention. Meanwhile, we are faced with a world that is constantly in flux, such that we have to frequently shift our attention from one piece of the environment to another and from one task to …


Using Otoacoustic Emissions To Evaluate Efferent Auditory Function In Humans, Simon Henin Feb 2014

Using Otoacoustic Emissions To Evaluate Efferent Auditory Function In Humans, Simon Henin

Dissertations, Theses, and Capstone Projects

The auditory system continually adapts to changes in the acoustic environment over short periods of time. This fine-tuning of its dynamics is mediated in part by the medial olivocochlear (MOC) bundle, a neural feedback loop which aids in the regulation of cochlear micro-mechanics. The ability to measure the response of the MOC system in humans may provide significant insight into unique cochlear functions, such as its sharp frequency selectivity and wide dynamic range. In humans the efferent system can be investigated non-invasively using otoacoustic emissions (OAEs). However, how OAEs can best be used to evaluate efferent function, the pitfalls associated …
