Smoking And Exercise: Mechanisms And Effects During Simulated And Genuine Quit Attempts, Stefanie De Jesus Dec 2015

Smoking And Exercise: Mechanisms And Effects During Simulated And Genuine Quit Attempts, Stefanie De Jesus

Electronic Thesis and Dissertation Repository

Cigarette smoking is a leading agent for premature morbidity and mortality among the global community. Most individuals surrender to tobacco use disorder due to the inability to cope with cravings and withdrawal symptoms. Exercise appears to provide acute relief. Currently, it is unclear how exercise attenuates these reductions. Furthermore, the available evidence has focused on acute outcomes besides smoking behaviour and is limited to simulated quit attempts. Three experimental studies were designed to address these outstanding issues. Not surprisingly, a bout of moderate intensity exercise was found in study 1 (chapter 2) to reduce cravings associated with a temporary period …


The Effects Of Alpha Stimulation On Induced Anxiety, Nolan Thomas Hill Dec 2015

The Effects Of Alpha Stimulation On Induced Anxiety, Nolan Thomas Hill

Electronic Theses and Dissertations

Anxiety is defined as an emotional and physical reaction that prepares us to confront a feared stimulus. Among the many measureable changes induced by anxiety are changes in facial electromyography (EMG), heart rate (HR), and sweat gland activity (EDG). At a pathological level anxiety interferes with cognitive processes. Currently, when anxiety crosses into the pathological level, it is treated with a variety of therapies that share in their use of periods of exposure to anxiety-inducing stimuli. Several devices have been developed to alter brain activity by transcranial electrical stimulation (TCES). One such device, Alpha-Stim®, has been shown to …


Implicit And Explicit Self-Esteem As Predictors Of Reactive And Proactive Aggression In Adolescent Boys And Girls, Maya Suter, Sebastien Urben, Sandrine Pihet, Cybele Bertoni, Jill De Ridder, Philippe Stephan Sep 2015

Implicit And Explicit Self-Esteem As Predictors Of Reactive And Proactive Aggression In Adolescent Boys And Girls, Maya Suter, Sebastien Urben, Sandrine Pihet, Cybele Bertoni, Jill De Ridder, Philippe Stephan

Journal of Adolescent and Family Health

This study aims at examining gender differences and their association with implicit and explicit self-esteem (SE), and reactive and proactive aggression in adolescents. Hundred and eighteen adolescents (60 boys and 58 girls) performed the Implicit Association Test assessing implicit SE. The Rosenberg Self-Esteem scale was used to measure explicit SE. Reactive and proactive aggression were assessed with the self-report Reactive and Proactive Aggression Scale. Results showed that girls characterized by both low explicit and implicit SE (insecure SE), or by high explicit but low implicit SE (defensive SE), showed more reactive aggression than girls reporting high explicit and implicit SE …


Executive Function Predictors Of Children's Talk, Jacqlyne D. Weber Jul 2015

Executive Function Predictors Of Children's Talk, Jacqlyne D. Weber

Undergraduate Honors Theses

Relatively few studies have investigated the relationship between executive functioning (EF) and language development, and even fewer have researched hot and cool EF as a predictor language development. This study is an investigation into the relationship between EF and language development in preschool aged children. More specifically, the ability for hot or cool EF to predict language, this will be the focus of the study. It was found that hot EF was a better predictor of language development in preschool aged children.

Belief About Nicotine Selectively Modulates Value And Reward Prediction Error Signals In Smokers, Xiaosi Gu, Terry Lohrenz, Ramiro Salas, Philip R. Baldwin, Alireza Soltani Feb 2015

Belief About Nicotine Selectively Modulates Value And Reward Prediction Error Signals In Smokers, Xiaosi Gu, Terry Lohrenz, Ramiro Salas, Philip R. Baldwin, Alireza Soltani

Dartmouth Scholarship

Little is known about how prior beliefs impact biophysically described processes in the presence of neuroactive drugs, which presents a profound challenge to the understanding of the mechanisms and treatments of addiction. We engineered smokers' prior beliefs about the presence of nicotine in a cigarette smoked before a functional magnetic resonance imaging session where subjects carried out a sequential choice task. Using a model-based approach, we show that smokers' beliefs about nicotine specifically modulated learning signals (value and reward prediction error) defined by a computational model of mesolimbic dopamine systems. Belief of "no nicotine in cigarette" (compared with "nicotine in …


Assessment Of Competence Restoration: Determining The Threshold, Andrea L. Dinsmore Jan 2015

Assessment Of Competence Restoration: Determining The Threshold, Andrea L. Dinsmore

Andrea L. Dinsmore

Discusses the legal precedent and research basis of evaluating a defendant's mental competency to stand trial, the variables that contribute to non-restorable incompetence to stand trial, and the differences between patients who are restorable to competency versus those who are not restorable to competency.


Exposure To Kynurenic Acid During Adolescence Increases Sign-Tracking And Impairs Long-Term Potentiation In Adulthood, Nicole E. Deangeli, Travis P. Todd, Stephen E. Chang, Hermes H. Yeh, Pamela W. Yeh, David J. Bucci Jan 2015

Exposure To Kynurenic Acid During Adolescence Increases Sign-Tracking And Impairs Long-Term Potentiation In Adulthood, Nicole E. Deangeli, Travis P. Todd, Stephen E. Chang, Hermes H. Yeh, Pamela W. Yeh, David J. Bucci

Dartmouth Scholarship

Changes in brain reward systems are thought to contribute significantly to the cognitive and behavioral impairments of schizophrenia, as well as the propensity to develop co-occurring substance abuse disorders. Presently, there are few treatments for persons with a dual diagnosis and little is known about the neural substrates that underlie co-occurring schizophrenia and substance abuse. One goal of the present study was to determine if a change in the concentration of kynurenic acid (KYNA), a tryptophan metabolite that is increased in the brains of people with schizophrenia, affects reward-related behavior. KYNA is an endogenous antagonist of NMDA glutamate receptors and …


Developing Executive Functions Through Mindfulness Training In School-Aged Children, Ashley Black Adams Jan 2015

Developing Executive Functions Through Mindfulness Training In School-Aged Children, Ashley Black Adams

PCOM Psychology Dissertations

Well-developed executive functions are necessary for successful classroom functioning. Students with executive function deficits can fall behind academically as well as socially and emotionally, relative to their same-aged peers. Effective interventions for developing executive functions within the school environment are essential for addressing this issue. This study examines changes in students’ executive functions as a result of their participation in a mindfulness training intervention. Participants included four ten-year old elementary school boys who took part in a ten-week mindfulness training intervention. The data were generated through pre and post assessments with an executive function teacher rating scale and a Goal-Attainment …


The Effectiveness Of A Computer-Assisted, Cognitive-Behavior Program For Treating Anxiety Symptoms In Children With Autism Spectrum Disorder, Jennifer A. Zabel Jan 2015

The Effectiveness Of A Computer-Assisted, Cognitive-Behavior Program For Treating Anxiety Symptoms In Children With Autism Spectrum Disorder, Jennifer A. Zabel

PCOM Psychology Dissertations

Autism Spectrum Disorder (ASD) is a complex and multifaceted, neurodevelopmental disorder that severely impacts children and families across a variety of settings. Prevalence rates of ASD are continuing to increase rapidly, with sizeable intervention and treatment costs placed on families and society. Further complicating the matter, many individuals with ASD also evidence co-occurring anxiety symptoms or disorders and tend to be at a higher risk for developing such problems when compared to other clinical populations or typically developing children. This study investigated the effectiveness of a computer-assisted CBT program, Camp Cope-A-Lot (CCAL), in regards to reducing anxiety symptoms in four …


Impact Of Group Cognitive Behavior Therapy On Adolescents With Deficits In Inhibition, Jessica L. Morley Jan 2015

Impact Of Group Cognitive Behavior Therapy On Adolescents With Deficits In Inhibition, Jessica L. Morley

PCOM Psychology Dissertations

Existing literature connects impulse control dysfunction to high-risk behaviors and negative life outcomes. Evidence-based interventions for children and adolescents who are at-risk or who are displaying significant levels of impulsive behavior are necessary in order to promote self-control, and in turn, positive life outcomes. This study investigated the impact of an eight-week, school-based GCBT intervention on cognitive inhibition and behavioral impulsivity in adolescent participants. The intention of the study was to evaluate the trend in inhibition and impulsivity from baseline to post-intervention assessments across five middle school students dually enrolled in a residential treatment facility and a center-based emotional support …


Adhd Children And Mental Health Service Use: Maternal Determinants, Katarina Krizova Jan 2015

Adhd Children And Mental Health Service Use: Maternal Determinants, Katarina Krizova

Theses and Dissertations--Family Sciences

The current study investigated maternal determinants of mental health service use, namely, individual child therapy, among preadolescent children diagnosed with ADHD. The Behavioral Model of Health Care Utilization (Andersen, 2008) was used as a theoretical framework for the study. Data from the last three rounds of ECLS-K dataset were employed to test a longitudinal model using Bayesian analysis. Socio-demographic variables and maternal mental health were tested as exogenous variables and mother-child relationship variables, discipline variables, and perceived maternal concern about child’s overall behavior and child’s emotional symptoms were tested as intervening variables. Results showed that only maternal mental health remained …


A Narrative Study Of Emotions Associated With Negative Childhood Experiences Reported In The Adult Attachment Interview, Lynne Hartman Jan 2015

A Narrative Study Of Emotions Associated With Negative Childhood Experiences Reported In The Adult Attachment Interview, Lynne Hartman

Antioch University Dissertations & Theses

Attachment patterns, which tend to be stable over time, are passed from one generation to the next. Secure attachment has been linked to adaptive social functioning and has been identified as a protective factor against mental illness. The parents’ state of mind with regard to attachment—as measured with the Adult Attachment Interview (AAI) (Main, Goldwyn, & Hesse, 2002)—predicts the attachment classification for the infant in Ainsworth’s Strange Situation Procedure (Ainsworth, Blehar, Waters, & Wall, 1978). Earned-secure individuals have overcome negative childhood experiences to achieve a secure state of mind in adulthood. Earned security, like continuous security, strongly predicts infant security …
