Participants are needed for a study of mental function. This study involves taking one of two FDA-approved medications for anxiety and/or muscle spasms: diazepam or baclofen. Both drugs cause sedation similar to that which you might experience in a minor surgical procedure. Participants will be paid $20/hour, and each of two sessions will last approximately six hours. After contacting us, we will provide you with more details and ask you some questions to see if you can participate. You must be 18-30 years old. Contact costudies@gmail.com
