Resting State Functional Connectivity In The Default Mode Network: Relationships Between Cannabis Use, Gender, And Cognition In Adolescents And Young Adults, Megan Ritchay Aug 2021

Resting State Functional Connectivity In The Default Mode Network: Relationships Between Cannabis Use, Gender, And Cognition In Adolescents And Young Adults, Megan Ritchay

Theses and Dissertations

Introduction: Cannabis is the most commonly used illicit substance in the United States, and nearly 1 in 4 young adults are current cannabis users. The psychoactive component of cannabis, THC, is active at cannabinoid receptors, type 1, or CB1 receptors. CB1 receptors play a critical role in neural development, and chronic cannabis use causes desensitization and downregulation of these receptors. Chronic cannabis use is associated with changes in resting state functional connectivity (RSFC) in the default mode network (DMN) in adolescents and young adults, although results are somewhat inconsistent across studies, likely due to differing methodologies. Additionally, cannabis effects appear …


Negative Urgency's Influence On State-Level, Emotion-Based Changes In Alcohol-Related Cognitions, Noah Wolkowicz Jul 2021

Negative Urgency's Influence On State-Level, Emotion-Based Changes In Alcohol-Related Cognitions, Noah Wolkowicz

Graduate Theses and Dissertations

This project expanded on the Acquired Preparedness Model of Risk (APMR) by examining how Negative Urgency (NU), the tendency to act rashly in negative emotional states, affects emotion-based changes in alcohol cognitions to produce risk for alcohol use. The APMR prioritizes the role of outcome expectancies as the means through which traits such as NU, convey alcohol use risk. However, this model treats these cognitions as static and often fails to assess their valence; further, alcohol-cognitions fluctuate in response to negative emotions and may become more salient during these states. Therefore, this study examined: 1) how NU impacts negative emotion-based, …


Differences In Internalizing Symptoms And Cognitive Functioning In Adults With Attention-Deficit/Hyperactivity Disorder And Sluggish Cognitive Tempo, Avery B. Ducey Jan 2021

Differences In Internalizing Symptoms And Cognitive Functioning In Adults With Attention-Deficit/Hyperactivity Disorder And Sluggish Cognitive Tempo, Avery B. Ducey

PCOM Psychology Dissertations

Sluggish cognitive tempo (SCT) is a recently identified mental health construct. Currently, no widely accepted diagnostic criteria for SCT exist, and it is not recognized in the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5). There is debate in the psychological community as to whether SCT is better conceptualized as an atypical presentation of attentiondeficit/ hyperactivity disorder (ADHD) or a unique symptom cluster comprised of ADHD and additional psychological and neurocognitive symptoms. When controlling for ADHD symptomatology, SCT has been found to be associated with internalizing symptoms, such as anxiety and depression, as well as …


Occupational Depression, Cognitive Performance, And Task Appreciation: A Study Based On Raven’S Advanced Progressive Matrices, Renzo Bianchi, Irvin Sam Schonfeld Jan 2021

Occupational Depression, Cognitive Performance, And Task Appreciation: A Study Based On Raven’S Advanced Progressive Matrices, Renzo Bianchi, Irvin Sam Schonfeld

Publications and Research

The Occupational Depression Inventory (ODI) was recently developed to assess depressive symptoms that individuals specifically attribute to their work. Research on the criterion validity of the instrument is still in its infancy. In this study, we examined whether the ODI predicted performance on, and appreciation of, a cognitively challenging test. In light of the link established between clinical depression and neuropsychological impairment, and considering that individuals with depressive symptoms are more likely to feel helpless under challenging circumstances, we hypothesized that occupational depression would be associated with poorer cognitive performance and a darkened appreciation of the task undertaken. We relied …
