This study examined the effect of tic-related talk on the vocal and motor tics of 2 boys with Tourette's syndrome. Using ABAB withdrawal designs, the boys were alternately exposed to conditions with and without talk of their tics. For both boys, vocal tics markedly increased when talk pertained to tics and decreased when talk did not pertain to tics, but motor tic covariance was less consistent.
本研究考察了与抽动相关的谈话对两名患有妥瑞氏综合征男孩的发声和运动抽动的影响。采用ABAB撤药设计，让这两名男孩交替暴露于有和没有提及他们抽动的情境中。对两名男孩而言，当谈话涉及抽动时，发声抽动明显增加，而当谈话不涉及抽动时则减少，但运动抽动的相关性不太一致。
