By definition, children with Tourette syndrome (TS) have had tics for over a year. They can often suppress their tics briefly and they do so more effectively when rewarded for successful suppression. It has not been known whether the ability to suppress tics develops only with practice over the years of having tics or whether the ability to suppress tics is present when tics initially occur. \citet{Greene_2015_NTsuppress} addressed this question in children whose tics had developed within the past few months. When children received tokens with monetary value for tic-free intervals, they had significantly more of these intervals compared to a baseline, unrewarded condition. This result suggests the possibility that behavior therapy for tics may work, at least for some children, even before TS can be diagnosed.   Most tic patients frequently try to suppress tics, but find suppressing them uncomfortable and distracting. However, those who are more satisfied with their ability to control suppress  their tics also report a higher quality of life \cite{26360257}. ### Sensory phenomena
