The Neural Correlates Of Emotion Reactivity And Regulation In Young Children With Adhd, Claudia I. Lugo-Candelas
The Neural Correlates Of Emotion Reactivity And Regulation In Young Children With Adhd, Claudia I. Lugo-Candelas
Doctoral Dissertations
Attention-deficit hyperactivity disorder (ADHD) is the most frequently occurring pediatric neurobehavioral disorder. Although emotion reactivity and regulation are frequently impaired in ADHD, few studies have examined these factors in preschool aged children with ADHD, and none have explored the neural correlates of emotion reactivity and regulation in this group though event-related potentials (ERPs). Children aged 4 to 7 with (n = 24) and without (n = 30) ADHD symptoms completed an attention task composed of four blocks: baseline, frustration, suppression, and recovery. In the frustration and suppression blocks, negative affect was induced by false negative feedback. During the …
The Effects Of Lipopolysaccharide-Induced Neuroinflammation On Learning And Forgetting In Juvenile Rats, Michele Barry
The Effects Of Lipopolysaccharide-Induced Neuroinflammation On Learning And Forgetting In Juvenile Rats, Michele Barry
Seton Hall University Dissertations and Theses (ETDs)
The inability to remember events experienced very early in life is referred to as Infantile Amnesia (IA) and has been observed in both humans and animals. Over the years interest in the phenomenon waned, but has recently increased with the discovery of new neurobiological methods to study brain function (e.g., Callaghan, Li & Richardson, 2014). The neurobiological mechanism behind IA has yet to be determined, but several innovative theories have been developed with these new research methods. The neurogenesis hypothesis theorizes that increased neurogenesis during early development disrupts previously established memories. The hippocampus, an area that mediates both the memory …
Working Memory Impairments In Chromosome 22q11.2 Deletion Syndrome: The Roles Of Anxiety And Stress Physiology, Ashley F. P. Sanders
Working Memory Impairments In Chromosome 22q11.2 Deletion Syndrome: The Roles Of Anxiety And Stress Physiology, Ashley F. P. Sanders
University of New Orleans Theses and Dissertations
Stress and anxiety negatively impact the working memory system by competing for executive resources. Broad memory deficits have been reported in individuals with chromosome 22q11.2 deletion syndrome (22q11.2DS). We investigated anxiety and physiological stress reactivity in relation to visuospatial working memory impairments in 20 children with 22q11.2DS and 32 typically developing children (M = 11.10 years, SD = 2.95). Results indicate reduced post-stress RSA recovery and overall increased levels of cortisol in children with 22q11.2DS. Additionally, anxiety mediated the relationship between 22q11.2DS and visuospatial working memory impairment. However, there was no indication that stress response physiology mediated this association. …
“My Logic Is Undeniable”: Replicating The Brain For Ideal Artificial Intelligence, Samuel C. Adams
“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 …
Using Spiral Dynamic Theory For Adult Civic Engagement Research And Social Justice Education, Lisa R. Brown
Using Spiral Dynamic Theory For Adult Civic Engagement Research And Social Justice Education, Lisa R. Brown
Adult Education Research Conference
Empirical civic engagement research based in a South American context. Participants included adult learner populations engaged in revolutionary protests that opposed private for-profit education in Chile. Findings were higher order Spiral Dynamic Theory thinking at the for-profits and lower civic engagement.
Does The Pain Of Rejection Promote The Pleasure Of Revenge? A Neural Investigation Of Cingulo-Striatal Contributions To Violence, David Chester
Does The Pain Of Rejection Promote The Pleasure Of Revenge? A Neural Investigation Of Cingulo-Striatal Contributions To Violence, David Chester
Theses and Dissertations--Psychology
Aggression is a dynamic and costly feature of human behavior. One reliable cause of aggression is social rejection, though the underlying mechanisms of this effect remain to be fully understood. Previous research has identified two psychological processes that are independently linked to aggressive retaliation: pain and pleasure. Given recent findings that pain magnifies the experience of pleasure, I predicted that the pain of rejection would promote the pleasure of aggression and thus, aggression itself. I also expected that this indirect effect of aggressive pleasure would only be observed among individuals with weaker self-regulatory abilities that are necessary to cope with …
