Brief Summary
This research is being done to determine whether transcranial direct current stimulation (tDCS) can improve certain mental abilities. In this research, a 9 volt battery is used to deliver very weak electrical current to the surface of the scalp while participants complete cognitive tasks. Our aim is to find out whether tDCS will improve task performance in adults over the age of 55.

Outcome Measures
Primary Outcomes (1)
Cognitive Test Performance
Cognitive test performance by subjects will be evaluated upon completion of enrollment to determine if tDCS improved performance on cognitive tests
The average time frame is 2 hours
Study Arms (2)
Sham Stimulation
SHAM COMPARATORtranscranial direct current stimulation that is ramped up and ramped down providing the sensation of tDCS without delivering the full amount of tDCS
Anodal Stimulation
EXPERIMENTALtranscranial direct current stimulation using Anodal stimulation over the area of interest
Interventions
delivery of transcranial direct current stimulation or sham stimulation for 20 to 60 minutes
