Effort, Avolition And Motivational Experience In Schizophrenia: Analysis Of Behavioral And Neuroimaging Data With Relationships To Daily Motivational Experience, Adam Culbreth Aug 2019

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 …

Dissociable Effects Of Monetary, Liquid, And Social Incentives On Motivation Across The Adult Life Span, Jennifer Crawford Aug 2019

Dissociable Effects Of Monetary, Liquid, And Social Incentives On Motivation Across The Adult Life Span, Jennifer Crawford

Arts & Sciences Electronic Theses and Dissertations

Humans are social creatures and, as such, can be motivated by aspects of social life, like approval from others, to guide decision-making in everyday life. Indeed, a common view in the aging literature is that older adults have a stronger orientation towards socioemotional goals or incentives, relative to other incentive modalities, like money, because of changing motivational priorities in older adulthood. In prior work, however, we found that older adults actually showed greater effects of monetary relative to primary (liquid) incentives, suggesting alternative interpretations of impaired motivational integration and/or slower adaptation to incentive conditions. The current study tested these alternatives, …
