However, there are marked individual differences in these age-related changes. The investigators' proposal will help characterize factors that contribute to this variability.\n\nParticipants will be pseudorandomly assigned to stress-manipulated or control groups. The investigators will give both groups a novel immersive navigation task, validated by the PI in healthy young adults. This paradigm gives participants the opportunity to either (a) flexibly draw on spatial memory in order to plan efficient routes to goal locations, or (b) fall back on inefficient, but cognitively less-demanding, stimulus-response associations (i.e., habits). Using neuroimaging and behavioral measures, the investigators' protocol will test whether experimentally-induced stress leads individuals to bring fewer details about future locations to mind when route planning, and whether such restricted prospective thought ultimately biases participants towards relatively inflexible, habitual actions.",[87,88,89],"Aging","Anxiety","Memory Impairment",[87,91,92,93],"Spatial Memory","Stress","fMRI","2026-04-16",{"date":96,"type":97},"2026-04-17","ACTUAL",{"date":99,"type":97},"2019-09-24",{"date":101,"type":81},"2026-09-01",{"name":5,"class":6},1]
