目的：许多神经精神障碍都涉及注意加工的异常。缺乏关于注意力如何影响抽动秽语综合征患者抽动频率的系统研究。方法：患者进行有节奏的手指运动，大约每2秒一次。每一个动作都会触发一个独特的视觉颜色刺激。患者被要求监测和记住他们的手指动作，由他们的动作引起的外部颜色，或他们的抽搐。16名成人抽动秽语综合征患者将每项任务执行两次：一次在抑制抽搐时，一次在不抑制抽搐时。结果如下：在“自由抽搐”的情况下，患者在注意手指运动或随后的颜色时，与注意他们的抽搐时相比，抽搐明显减少。注意手指产生的抽搐最少。在抽搐抑制过程中，抽搐频率在所有条件下都降低到相同的水平。结论：将注意力从抽搐上移开，可以显著降低抽搐频率。这种注意力过程可以通过调节运动噪声来进行。
Objective: Many neuropsychiatric disorders involve abnormal attentional processing. Systematic investigations of how attention may affect tic frequency in Tourette syndrome are lacking. Method: Patients performed rhythmic finger movements, approximately once every 2 s. Each movement triggered a unique visual color stimulus. Patients were asked to monitor and remember their finger actions, the external colors caused by their actions, or their tics. Sixteen adult Tourette syndrome patients performed each task twice: once while inhibiting tics, and once without inhibiting tics. Results: During the “freely tic” condition, patients had significantly fewer tics when attending to finger movements, or to the ensuing colors, compared with when attending to their tics. Attention to fingers produced the fewest tics overall. During tic suppression, tic frequency was reduced to an equal level in all conditions. Conclusions: Focusing attention away from tics significantly reduces tic frequency. This attentional process may operate by regulating motor noise.
