Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Grant permission for the researchers to view medical records associated with their language/cognitive difficulties
Complete a questionnaire, provide a health history, and take some pencil-and-paper tests of problem-solving and memory in order to verify eligibility to participate and to able to safely undergo the experimental procedures.
Complete several tasks (e.g., saying words out loud, naming objects, drawing designs, remembering lists of words, searching for images or letters, and/or completing puzzles) based upon a number of cognitive functions such as language, memory, vision, processing, and perception.
Wear electrodes that will be placed on the scalp with a large rubberized band. These electrodes will administer very weak electrical current (tDCS) from a 9 volt battery for 20 to 60 minutes.
Participation in several study conditions. The exact conditions and their order will be randomized. Under some conditions, participants may receive active stimulation (tDCS) and under other conditions, they may receive sham stimulation.
The experimental sessions will last approximately 2 hours and participants may be asked to have more than one testing session in a day or to return for additional sessions.
Have a Magnetic Resonance Imaging (MRI) brain scan.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Anodal Stimulation
transcranial direct current stimulation using Anodal stimulation over the area of interest
transcranial direct current stimulation
delivery of transcranial direct current stimulation or sham for 20 to 60 minutes
Cathodal
transcranial direct current stimulation using cathodal stimulation over the brain area of interest
transcranial direct current stimulation
delivery of transcranial direct current stimulation or sham for 20 to 60 minutes
Sham Stimulation
transcranial direct current stimulation that is ramped up and ramped down providing the sensation of tDCS without actually delivering tDCS
transcranial direct current stimulation
delivery of transcranial direct current stimulation or sham for 20 to 60 minutes
