The Role Of Mindfulness In Self-View Investment: Neural And Subjective Indicators, Hadley Rahrig
The Role Of Mindfulness In Self-View Investment: Neural And Subjective Indicators, Hadley Rahrig
Theses and Dissertations
Self-concept is strongly influenced by beliefs about one’s personal psychological attributes, and these beliefs are held with varying degrees of confidence and consequence. Hence, it is investment in self-views of those attributes that helps to regulate and maintain stable self-concept. Self-view investment is relevant to numerous self-related functions, but high self-view investment can also contribute to maladaptive self-views. Theory suggests that mindfulness cultivates a less personal, more objective perception of one’s thoughts, emotions and behaviors, and training in mindfulness has been shown to alter self-referential processing. The current pilot study (N=21) investigates the possible role of dispositional mindfulness in two …
Integrating Genetics And Neuroimaging To Study Subtypes Of Binge Drinkers, Megan E. Cooke
Integrating Genetics And Neuroimaging To Study Subtypes Of Binge Drinkers, Megan E. Cooke
Theses and Dissertations
Risky alcohol use is a major health concern among college students, with 40.1% reporting binge drinking (5 or more drinks in one occasion) and 14.4% reporting heavy drinking (binge drinking on 5 or more occasions) in the past month. Risky alcohol use is thought to be the result of a complex interplay between genes, biological processes, and other phenotypic characteristics. Understanding this complex relationship is further complicated by known phenotypic heterogeneity in the development of alcohol use. Developmental studies have suggested two pathways to risky alcohol use, characterized by externalizing and internalizing characteristics, respectively. However, the underlying biological processes that …
Acute And Chronic Effects Of Inhalants In Intracranial Self-Stimulation, Matthew Tracy
Acute And Chronic Effects Of Inhalants In Intracranial Self-Stimulation, Matthew Tracy
Theses and Dissertations
Inhalants are a loosely defined diverse group of volatile substances which people abuse. Despite widespread misuse of inhalants, there are limited preclinical methods available to study the reinforcement-like properties of inhalants. One procedure which has demonstrated substantial promise as a tool to investigate inhalant pharmacology is the intracranial self-stimulation (ICSS) procedure. ICSS utilizes pulses of electrical stimulation to the mesolimbic reward pathway to serve as a temporally defined and controlled operant reinforcer with a highly adjustable efficacy. The first aim of the project was to characterize the effects of commonly abused inhalants: including toluene, trichloroethane, nitrous oxide, isoflurane and R134a …
