Ptsd From Childhood Trauma As A Precursor To Attachment Issues, Christy Owen Sep 2016

Ptsd From Childhood Trauma As A Precursor To Attachment Issues, Christy Owen

Fidei et Veritatis: The Liberty University Journal of Graduate Research

The past 20 years have been turbulent regarding Reactive Attachment Disorder (RAD), with conflicting research about its causes, effects, treatment, and prognosis. The current diagnostic criteria in the DSM-5 fails to adequately address this disorder. A number of deviant and maladaptive behaviors common amongst children with RAD are not even mentioned in the diagnostic criteria. As such, the diagnostic definition is almost unidentifiable or incompatible with real-life conduct manifestations of the disorder. Rather, this author contends that RAD is foundationally a unique and extreme form of Posttraumatic Stress Disorder (PTSD) from Early Childhood Trauma. The child endured unspeakable neglect and/or …


“My Logic Is Undeniable”: Replicating The Brain For Ideal Artificial Intelligence, Samuel C. Adams Apr 2016

“My Logic Is Undeniable”: Replicating The Brain For Ideal Artificial Intelligence, Samuel C. Adams

Senior Honors Theses

Alan Turing asked if machines can think, but intelligence is more than logic and reason. I ask if a machine can feel pain or joy, have visions and dreams, or paint a masterpiece. The human brain sets the bar high, and despite our progress, artificial intelligence has a long way to go. Studying neurology from a software engineer’s perspective reveals numerous uncanny similarities between the functionality of the brain and that of a computer. If the brain is a biological computer, then it is the embodiment of artificial intelligence beyond anything we have yet achieved, and its architecture is advanced …


Understanding Mental Toughness And Stress: The Role Of Cortisol, Alexis K. Satterwhite Ms. Jan 2016

Understanding Mental Toughness And Stress: The Role Of Cortisol, Alexis K. Satterwhite Ms.

Honors Program Theses

Mental toughness research aims to understand how two people of the same skill level, experience, and background react to pressure and stress, with one succumbing to the pressure while another succeeds (Clough & Strycharczyk, 2012). This study used Clough, Earle, and Sewell’s (2002) four C’s of mental toughness (commitment, challenge, control, and confidence) as a theoretical framework. The current study aims to explore physiological aspects of mental toughness through cortisol, a stress hormone that is released as an internal reaction to some type of threat occurring externally to the body (Kottler & Chen, 2011). The relationships between mental toughness and …

The Effects Of Pet Ownership On Anxiety And Depression Among Trauma-Exposed College Students, Dung N. Nguyentran, Marlene A. Michniak, James J. Jung, Christine Q. Do

Undergraduate Research Posters

Rates of anxiety and depression are prevalent in college students and can be attributed in part to stress and trauma-related events. However, studies suggest that pet ownership has the possibility of alleviating symptoms of anxiety, depression, negative emotions, and suicide. The purpose of this study was to determine the relationship between pet ownership and levels of anxiety and depression among those who have experienced a traumatic event. The sample was comprised of five hundred and forty-seven VCU students who completed an online survey from Spit for Science during their junior year. Linear regressions were performed to determine the nature and …
