Study Summary
This study will investigate the extent to which tDCS to dorsolateral prefrontal cortex (or dlPFC) impacts memory performance as a function of time-of-day in younger and older adults.
Primary Outcome
To measure episodic memory performance, participants will perform a recollection task. They will first study picture and word stimuli (encoding phase). On the subsequent memory test (retrieval phase), participants will be asked to differentiate between studied and non-studied items, as well as recollecting the previous format for studied items (i.e. recollecting the picture or word). For each tested item, participants will also be asked to make a confidence judgement about their response. The pr
Interventions
- DEVICE Sham tDCS
- DEVICE Active tDCS
