Effort, Avolition And Motivational Experience In Schizophrenia: Analysis Of Behavioral And Neuroimaging Data With Relationships To Daily Motivational Experience, Adam Culbreth
Arts & Sciences Electronic Theses and Dissertations
Recent research has suggested an association between motivational impairment in those with schizophrenia and reduced willingness to expend effort on experimental tasks. However, few studies have examined the neural correlates of effort-based decision-making in those with schizophrenia. In the current study, we aimed to examine willingness to expend effort, the associated neural circuitry of effort-based decision-making, and the impact of experimentally-defined effort-based decision-making on daily motivational experience in schizophrenia. We recruited 28 individuals with schizophrenia and 30 healthy controls to perform an effort-based decision-making task while undergoing fMRI scanning. In order to assess whether willingness to expend effort was associated …

Social Networking Website Use And Eating Pathology: Relations, Moderators, And Motivation To Improve, Michelle S. St. Paul
Social Networking Website Use And Eating Pathology: Relations, Moderators, And Motivation To Improve, Michelle S. St. Paul
Arts & Sciences Electronic Theses and Dissertations
Social networking website (SNW) use has been found to be associated with decreased body image or esteem and increased eating disorder (ED) symptoms. In turn, SNW use may also be associated with decreased motivation to improve body image (BI) and reduced self-efficacy in one’s ability to do so. However, the impact of SNW use on motivation or self-efficacy to improve BI has not yet been studied. Also, particular moderators of the relationships between SNW and eating pathology have not yet been evaluated. This study aimed to: 1) replicate past literature by examining the relation between SNW use and eating pathology, …
