Cerebellum-Seeded Functional Connectivity Changes In Trait-Anxious Individuals Undergoing Attention Bias Modification Training, Katherine Elwell
Cerebellum-Seeded Functional Connectivity Changes In Trait-Anxious Individuals Undergoing Attention Bias Modification Training, Katherine Elwell
All NMU Master's Theses
Anxiety and anxiety related disorders are increasing at a drastic rate in the past decade, with the NIMH reporting that 31.1% of U.S. adults will experience an anxiety disorder at some point in their lives. Anxiety is commonly characterized by increased attention bias to threat. Attention Bias Modification (ABM) is a new treatment used to reduce individual’s attention bias towards threat. The extent to which ABM leads to underlying neural changes is still unknown. The cerebellum is a neglected brain structure, with new research provides evidence that cerebellum’s functional connectivity and shared networks with threat processing regions has a direct …
Attention Deficit Hyperactivity Disorder With Comorbid Anxiety/Depression In Adults: Impacts On Neuropsychological Functioning, Cristina Valdivieso Bain
Attention Deficit Hyperactivity Disorder With Comorbid Anxiety/Depression In Adults: Impacts On Neuropsychological Functioning, Cristina Valdivieso Bain
Psychology Theses & Dissertations
ADHD comorbidity with other disorders is high in the adult population (over 44% of individuals carry a second diagnosis, 25% anxiety, 18.6% in depression). Separately, these disorders can impact scores on neuropsychological assessments. Little research has investigated how comorbidity among ADHD and other disorders impacts test scores collectively. Given high rates of comorbidity between ADHD and anxiety/depressive disorders and the potential impact on neuropsychological functioning, the current study examined how these comorbid disorders collectively impact cognition. Specifically, the present study investigated differences in full scale intelligence, general ability, and cognitive proficiency on the WAIS-IV between those diagnosed with ADHD only …
Characterization Of Somatosensory Processing In Relation To Schizotypal Traits In A Sample Of Nonclinical Young Adults, Maureen Patricia Daly
Characterization Of Somatosensory Processing In Relation To Schizotypal Traits In A Sample Of Nonclinical Young Adults, Maureen Patricia Daly
Dissertations, Theses, and Capstone Projects
A core feature of schizophrenia spectrum disorders (SSDs) is a basic sensory (e.g., visual, auditory) processing disruption, yet few studies have examined somatosensation. The current dissertation project examined somatosensory processes among individuals at varying degrees of psychometric risk for psychosis using tactile texture and spatial discrimination and letter recognition tasks. Differential patterns of associations of somatosensory abilities with schizotypal trait dimensions (positive, negative, disorganized), independent of anxiety and depressive symptoms, and the relative contributions of bottom-up (peripheral and morphologic features) versus top-down (error types) processing were examined. It was hypothesized that: 1) performance on somatosensory tasks would account for significant …
