Detailed Description
This study will look at the effects of a painless, non-invasive form of brain stimulation, called transcranial direct current stimulation, or tDCS. tDCS is thought to increase the brain's ability to change. Participants will be assigned to one of three groups by chance. Two groups will receive tDCS at a level expected to increase the brain's ability to change, while the other group will receive tDCS at a level not thought to affect the brain's ability to change.
