Examining The Effects Of Stress And Age On Neural Reward Processing: Considerations For The Role Of Individual Differences In Autonomic Reactivity, William Mccuddy

Dissertations (1934 -)

Acute stress is unavoidable and may hinder basic reward processing underlying adaptive decision-making. Additionally, older adults may be at an increased risk of poor decision-making after exposure to acute stress due to age-related changes in cognitive and autonomic functioning. The current study assessed the influence of acute stress, autonomic reactivity, and age on a simple behavioral task during fMRI. Specifically, old and young adults completed a basic reward processing paradigm (i.e., where participants received monetary rewards and punishments) after exposure to acute stress (i.e., social evaluative cold pressor) or control procedure between-subjects. In the young group, differential responses for monetary …
