Study Summary

This trial will study whether electric stimulation of speech and non-speech regions can improve speech motor learning and help treat speech impairments.

Who is the study for?
This trial is for native English speakers who learned the language from birth at home and have not been exposed to certain languages with specific consonant clusters. Participants must pass a hearing test and have no history of speech, language, or hearing disorders. They should also not have any tDCS risk factors like skin damage where the device attaches, implants that react to electricity or magnets, or metal in their body.Check my eligibility
What is being tested?
The study tests how different types of electrical brain stimulation affect learning new speech sounds. Healthy adults will practice nonwords while receiving one of six treatments: positive or negative stimulation over speech motor areas, positive or negative stimulation over frontal regions, negative stimulation over non-speech motor areas (positive already done), or sham (fake) treatment.See study design
What are the potential side effects?
tDCS can cause mild side effects such as itching, tingling, headache during application; fatigue after sessions; nausea; and discomfort on scalp under electrode placement. Serious side effects are rare but may include seizures and mood changes.
