研究概览
简要总结
UCLA researchers looking for healthy older adults (aged 65+) to participate in a study investigating how writing about experiences can affect your brain and body.
Once a week for 6 weeks, participants will write about their experiences and fill out online questionnaires. Participants will also come to the UCLA campus to complete a neuroimaging session (fMRI), provide a blood spot sample, and fill out questionnaires 2 times: once prior to the 6-week writing period and once immediately after the 6-week writing period.
