Complex Trauma In Childhood And Its Relationship To Emotion Regulation And Distress Tolerance In College Students, Elizabeth Lombardo

USC Aiken Psychology Theses

Objective: The influence of childhood trauma has been found to be related to difficulties in emotion regulation and distress tolerance in young adulthood (Berenz et al., 2018a, 2018b). Research has shown that childhood abuse and adversities such as neglect or emotional abuse results in impaired processes related to the development of emotion regulation and efficient interpersonal skills, while also resulting in symptoms reflecting disordered affective self-regulation (Cloitre et al., 2009; Shipman, Edwards, Brown, Swisher, & Jennings, 2005; Shipman, Zeman, Penza, & Champion, 2000). Research has examined emotional regulation and distress tolerance in the context of childhood trauma but has not …

The Relationship Of Executive Function And Alpha Band Activity During The Eriksen Flanker Task: An Eeg Study, Destiny A. Willis

USC Aiken Psychology Theses

Objective: Neural frequencies, measured by electroencephalogram, can be indicative of certain cognitive states. One oscillation, called the alpha wave, has become a proxy for the cognitive ability related to attention. Research suggests that anxiety may result in atypical alpha oscillations when engaging in an attention task, thereby also resulting in potentially dysfunctional attentional abilities. The current study aimed to investigate the relationship between alpha wave frequency, executive function, trait anxiety symptoms, depressive symptoms, and response selection.

Method: The Eriksen flanker task was used to measure response selection, while an electroencephalogram recorded alpha brainwave activity (N = 47). This study incorporated …

The Influence Of Depressive Symptoms On Frn Amplitude: An Eeg Study, Jonathan Burton

USC Aiken Psychology Theses

Background: Individuals diagnosed with depression demonstrate differences in neural activation patterns detectable using electroencephalogram (EEG). One of these differences has been specifically linked with the event-related potential (ERP) component called feedback-related negativity (FRN). In participants diagnosed with depression, the FRN has been shown to have larger amplitudes in response to negative feedback. However, previous research has only specifically looked at the difference of this amplitude between groups, specifically those with and those without a diagnosis of depression. Objective: The goal of the current study was to examine whether a continuous range of depressive symptoms in participants can predict FRN amplitudes, …

The Impact Of Childhood Trauma As Moderated By Ptsd, Relationship With Caregiver, And Rumination, Aislyn M. Allen

USC Aiken Psychology Theses

The current study explored the relationship between childhood trauma and deliberate rumination, as well as PTSD symptomology, psychological and physiological functioning. Participants consisted of 55 undergraduate students, ages 18-23; who completed measures about a specific traumatic event, psychological functioning, parental attachment, PTSD symptoms, deliberate rumination, childhood maltreatment, and a demographics questionnaire. Reported childhood trauma was a specifically identified traumatic life event, child maltreatment, or having a parent with a substance abuse or mental disorder. Following completion of measures, participants were asked to answer questions while heart rate, heart rate variability, and electrodermal activity were monitored. Results indicated there was relation …

Interactions With Horses Is Associated With Higher Mindfulness And Heart Rate Variability And Lower Electrodermal Response In College Students, Sarah Mary Wach

USC Aiken Psychology Theses

A wealth of research has revealed psychological and physiological benefits of interactions with animals. As yet, research is limited to smaller animals such as dogs and cats and has not examined the benefits of human-horse interactions. The present study examined the effects of video-simulated human-horse interactions compared with simulated interactions with a car and a person on state mindfulness and physiological arousal. The relationship between trait mindfulness and horse experience was also examined. Undergraduate students with (n = 16) and without experience with horses (n = 26) were recruited with the exclusion criteria of a fear of horses. …
