The goal of this clinical study is to learn more about the timing of tics (sudden, fast movements and sounds that people do and make without meaning to) in people who have multiple tics that have been going on for more than one year. The main questions it aims to answer are: 1. See whether a tic's timing is related to other characteristics of the tic, like how long it has been happening and how well the person can control/stop that tic 2. See whether the timing of a tic can tell us how well the person can control/stop that tic 3. See whether tic treatment changes the timing of tics, and if the timing of a tic has anything to do with how well treatment will work to stop it Participants will meet with a study researcher to learn more about the study, ask questions, and decide whether or not they would like to be involved. If they decide to do the study, they will meet with the researcher 6 times: 1. During the first visit, the study researcher will ask questions about the participant's life, tics, and other psychological symptoms. The researcher will watch the participant's tics for 10 minutes. The participant will do a computer task where they follow instructions to tic or not tic. 2. During the second visit, the study researcher will treat one of the participant's tics. 3. During the third visit, the study researcher will treat another one of the participant's tics. 4. During the fourth visit, the study researcher will treat another one of the participant's tics. 5. During the fifth visit, the study researcher will treat another one of the participant's tics. 6. During the sixth visit, the study researcher will ask questions about the participant's tics and other psychological symptoms. The participant will do a computer task where they follow instructions to tic or not tic.
