Project Summary When faced with a difficult problem, people often rely on their past experiences. Healthy aging impairs both episodic memory and everyday problem solving. Dr. Nadia Brashier, a postdoctoral fellow in the Psychology Department at Harvard University, and her mentor, Dr. Daniel Schacter, will use the Research Supplement to Promote Diversity in Health-Related Research (PA-20-222) to investigate whether altered connectivity between large-scale brain networks underlies older adults’ deficits. This supplement will enhance the training of Dr. Brashier, an early career scientist from a disadvantaged background. She will develop expertise in the cognitive neuroscience of aging, with a focus on using functional magnetic resonance imaging (fMRI) methods in older adults.
