Effects of brain stimulation on beat perception and motor performance

For this study we are seeking healthy individuals with no hearing problems between the ages of 18-45. Please check that none of the following exclusion criteria apply to you: use of psychoactive drugs/medication, use of hearing aid, pacemaker or any metal implants in body, susceptible to headaches or migraines, blackouts or seizures, is pregnant, or susceptibility to skin irritation due to eczema.

In this study, you will come to the lab for up to three sessions. Each session lasts about 1-1.5 hours. During each session, you will complete different musical tasks on a computer. Before you begin the experimental tasks, the researcher will complete the tDCS setup, which involves attaching one electrode to your scalp and another electrode to your forehead. A weak current is passed through the electrodes once the tDCS is turned on – some participants report an itching sensation, although most individuals adjust to the sensation quickly. You will then complete various tasks assessing your musical rhythm skills, including tapping along to the beat of musical clips and tapping a rhythm stored in memory. You may also be asked to complete surveys as a part of this study, asking questions about your demographics and musical background.
