Neurocorrelates Of The Mirror Neuron System In Children With Chromosome 22q11.2 Deletion Syndrome, Ade Marais
Neurocorrelates Of The Mirror Neuron System In Children With Chromosome 22q11.2 Deletion Syndrome, Ade Marais
University of New Orleans Theses and Dissertations
Activation of brain regions that make up the mirror neuron system (MNS) is thought to reflect processing and perceiving behavior, action, and intentionality of other organisms. Sensing and perceiving motor behavior in others is an important component of understanding and participating in social interactions. Children with chromosome 22q11.2 deletion syndrome (22q11.2DS) are diagnosed with serious medical, cognitive, and socio-emotional symptoms. Atypical development and function of the MNS may underpin some aspects of socio-emotional impairment and autism spectrum disorder (ASD)-like symptomology reported. This study of the MNS investigates differences in activation in the operculum, sensorimotor areas, and basal ganglia (BG) in …
Effects Of Nicotine Exposure On Methamphetamine Oral Self-Administration, Extinction, And Reinstatement In Adolescent Rats, Zachary Robert Harmony
Effects Of Nicotine Exposure On Methamphetamine Oral Self-Administration, Extinction, And Reinstatement In Adolescent Rats, Zachary Robert Harmony
Electronic Theses, Projects, and Dissertations
Adolescence is a vulnerable developmental period in regards to drug initiation and use. The gateway hypothesis suggests that adolescent cigarette smoking may result in a heightened risk for methamphetamine use. However, little is understood about the role of nicotine on adolescent methamphetamine addiction. The aim of the present study was to determine whether early, late, or continuous adolescent nicotine exposure would alter oral methamphetamine self-administration, extinction, or reinstatement. A total of 164 male and female Sprague-Dawley rats were pretreated with saline or nicotine (0.16, or 0.64 mg/kg, sc) beginning on postnatal day (PD) 25 for 10 consecutive days. On PD …
Mediators And Moderators Of Childhood Family Adversity And Adult Cortisol Response: The Role Of Marital Conflict Behavior, Jeffrey P. Winer
Mediators And Moderators Of Childhood Family Adversity And Adult Cortisol Response: The Role Of Marital Conflict Behavior, Jeffrey P. Winer
Doctoral Dissertations
Childhood family adversity influences behavioral and physiological response processes to acute interpersonal stress. Additionally, conflict behaviors in marriage are primary determinants of stress response and related psychological problems in adulthood. As little research has examined these two important literatures simultaneously, further work is warranted to clarify the role of marital conflict behavior in the relation between childhood family adversity and adult cortisol response to conflict. The current study examined relations between childhood family adversity, observed marital conflict behaviors, and salivary cortisol in response to acute marital conflict among 228 different-sex newlywed couples. We examined intrapersonal “actor” effects as candidate mediators …
Emotion Dysregulation And Functional Connectivity In Children With And Without A History Of Major Depressive Disorder, Katherine Lopez
Emotion Dysregulation And Functional Connectivity In Children With And Without A History Of Major Depressive Disorder, Katherine Lopez
Arts & Sciences Electronic Theses and Dissertations
Recent interest has emerged in understanding the neural mechanisms by which deficits in emotion regulation (ER) may relate to the development of depression. Cortico-limbic alterations reported in emotion dysregulation and depression may be one possible link. We examined the relationships between emotion dysregulation in school age, corticolimbic resting state functional connectivity (rs-FC) in preadolescence, and depressive symptoms in adolescence. Participants were 143 children from a longitudinal preschool onset depression study who completed the Children Sadness Management Scale (CSMS), Child Depression Inventory (CDI), and two resting state MRI scans. We examined rs-FC between four primary regions of interest (ROIs; bilateral dorsolateral …
The Relationship Of Early Class Start Times On Sleepiness And Driving Behaviors In An Emerging Adult Population, Jessica L. Fry
The Relationship Of Early Class Start Times On Sleepiness And Driving Behaviors In An Emerging Adult Population, Jessica L. Fry
Psychology Theses & Dissertations
Teenage driver sleepiness is a recent concern for preventing motor vehicle fatalities. Early school start times limit the amount of sleep teenage high school students acquire during the week and have been related to increased crash risk. The current study extends this finding to teenage and emerging adult college students. The author examined the link between sleepiness and teenage driving behaviors, including the relationship between school start times and sleepiness. In all, 536 participants were recruited to participate in an online survey assessing driving and sleep behaviors. Correlations and path analysis found that sleepiness fully mediated the relationship between early …
